The packed-bed conditioner has been the focus of many R&D projects on Desiccant De-humidifiers. More recent R&D on packed-bed heat and mass exchangers includes the work of [9] in which the performance of packed-bed heat and mass exchangers flooded with lithium chloride solutions were experimentally measured. The researchers first implemented their conditioner and regenerator as internally cooled units using either copper tubes or polypropylene tubes as the contact surface. However, the copper tubes were too easily corroded by the desiccant, and the polypropylene tubes were too difficult for wetting.

[10] modelled and experimentally measured the performance of packed-bed, lithium chloride heat, and mass exchangers that used a random, polypropylene packing with a volumetric surface area of 210 m2 per m3. They reported that the lithium chloride solution did not uniformly wet the packing because of its high surface tension.

High flooding rates are necessary to keep the desiccant cool and complete wetting. But High flooding rates may cause carryover of liquid desiccant droplets into air stream and also is responsible for pressure drop in air flow. Conditioners that are internally cooled do not have to operate at the high flooding rates of packed-bed units as the desiccant temperature is maintained close to coolant temperature [11]. A cross flow heat exchanger is shown   inthe Fig. 5 which is internally cooled by  coolant  where  the process air flow and desiccant flow contact at right angles. A coolant liquid provided from a cooling tower or chilled water enters through the pipe section throughout the heat exchanger and hence internally cooling desiccant.

Cross flow heat exchanger

At low liquid desiccant temperature the vapour pressure also remains low and thus allowing more moisture absorption into the liquid desiccant.

6. Solar Hybrid Desiccant Cooling System

[12] has investigated the solar hybrid desiccant air cooler (SHDCS) shown in Fig. 7 for its applicability and performance in commercial premises with high latent cooling load in subtropical Hong Kong. Vapour compression chiller was used to provide chilled water to a supply air cooling coil. Desiccant wheel was adopted and its regenerating heat primarily came from the solar thermal gain of the evacuated tubes. The desiccant wheel dehumidified the fresh air to the required level and the supply air coil provided the sensible cooling. For commercial premises with high latent cooling load (60% RH) It is observed that SHDCS had more superior cooling and energy performances than the conventional centralized air-conditioning (AC) system in the subtropical Hong Kong. The annual primary energy consumption saving could be around 49.5% in comparison to conventional vapour compression systems.

 

Figure 7. Solar Hybrid Desiccant Cooling system with solar heating for desiccant regeneration, Desiccant Dehumidification and compression based cooling

[13] simulated a hybrid desiccant cooling system comprising the conventional vapour compression air conditioning system coupled with a liquid desiccant dehumidifier which was regenerated by solar energy. The study suggested that, when the latent load constitutes 90% of the total cooling load, the system can generate up to 80% of energy savings. [14] conducted a comparative study of a standalone VAC, the desiccant-associated VAC, and the desiccant and evaporative cooling associated VAC as shown in following figure. The authors found an increase of cold production by 38.8–76% and that of COP by 20–30%. [15] have studied the performance of three possible hybrid system configurations in supermarket applications and have compared their performance with traditional VAC system. As reported, a total air conditioning saving ranging from 56.5% to 66% could be achieved for specified design conditions (ambient conditions: 30 °C, 16 g/kg.da; indoor conditions: 24 °C, 10.4 g/kg.da; room sensible heat ratio: 0.35). [16] have modelled the performance of a desiccant integrated hybrid VAC system. The waste heat rejected from a VAC cycle is utilized to activate a solid desiccant dehumidification cycle directly. The performance sensitivity of a first generation prototype hybrid VAC system to variable outdoor conditions has been studied and compared to the performance of conventional VAC systems. Results showed that the performance improvement over VAC systems could be 60% at the same level of dehumidification under ARI summer conditions. [17] have simulated the transient performance of a hybrid desiccant VAC system for the ambient conditions of Beirut. The annual energy consumption of the hybrid system in comparison with the conventional VAC system has been studied for the entire cooling season. A payback period less than five years was achieved.

[18] has reviewed various thermally activated cooling technologies and has tabulated a summary of the main features of up-to-date thermally activated cooling technologies which is shown in table 1. It is observed that of all the technologies liquid desiccant cooling technologies has lowest regeneration temperatures and has better COP value compared to other technologies.

7. Conclusion

Liquid Desiccant dehumidification systems although limited to industrial applications, but could exhibit huge potential energy and economic savings for HVAC industry by

• Reducing the peak electricity demand created by compressor – based AC’s
• Improving the indoor air quality and reduce the indoor humidity levels that could be difficult to be controlled by conventional air conditioners.

Hybrid liquid desiccant cooling technology has demonstrated its superior performance for hot and humid climatic conditions and could save more that 50% operational energy saving compared to conventional vapour compression cooling technology. One of most important advantages of desiccant cooling systems undoubtedly lies in the possibility of using solar energy which can be effectively utilized to regenerate saturated liquid desiccants by using relatively low-cost solar thermal collectors. LDAC’s have low regeneration temperatures (60 - 90°C) and have high COP values (0.5 – 1.2) compared to other thermally activated cooling technologies.

Future research should include development of non corrosive desiccant materials having lesser regeneration temperatures, developing control strategies to prevent mixing of liquid desiccant droplets in the process air stream and design of small and compact systems for application in residential buildings.

Solar energized Liquid Desiccant Air Conditioning – A review (Part I)

Abstract

A review on Liquid Desiccant based cooling technologies with special focus on advances in
liquid desiccant materials and configurations of heat and mass exchangers have been
discussed. Performance comparison and energy saving potential of a hybrid liquid desiccant
cooling system based on vapour compression based sensible cooling and liquid desiccant
based dehumidification in comparison to conventional vapour compression system has been
reviewed. Hybrid liquid desiccant cooling system has enormous energy and cost saving
potential especially in hot and humid regions like India. The ability of Liquid Desiccant
cooling technology to be energized by Solar thermal makes it an attractive alternative to high
electrical energy intensive conventional vapour compression based cooling for residential and
commercial HVAC applications.

Keywords: Liquid Desiccant, Dehumidification, Vapour Compression, Solar Thermal.

1. Introduction

India is a tropical country and more than 80% of Indian Sub continental area falls under
Warm humid or Composite Climatic zone [1]. These climatic zones are characterized by high
annual average temperatures and high humidity. With rapid urbanization and industrialization
in India, there is sharp rise in air conditioning load in Industrial, commercial as well as
residential buildings.

 The Air conditioning load could be broadly classified as sensible load and latent load.
Conventional vapour compression Air conditioners (VAC) meet the total air conditioning
load by cooling the air below the dew point temperature and thus condensing the moisture.
These systems require evaporator temperatures to be maintained much lower than required to
achieve sensible cooling alone. The dew point temperature is much below the set temperature
level and hence process air requires further heating to bring its temperature to set temperature
level. This requirement increases the capacity rating of the compressors and requires high
electricity and consequently operates at reduced coefficient of performance (COP) [2].

There is a necessity to separate the latent cooling load and sensible cooling load and handle
them separately so as to improve the COP of the air conditioners. The desiccant cycles can be
used to reduce the moisture content of air by partially converting latent cooling load to
sensible cooling load and then meeting the load by VAC’s. These systems with vapour
compression cycle for meeting sensible cooling load and liquid – desiccant cycle for latent
cooling load are called hybrid systems.

2. Liquid desiccant dehumidification and air conditioning

A desiccant material has a strong attraction for water vapour. Desiccants are commonly used
in industrial applications where low dew-point air is needed. The strength of a desiccant can
be measured by its equilibrium vapour pressure (i.e., pressure of water vapour that is in
equilibrium with the desiccant). This equilibrium vapour pressure increases roughly
exponentially with the temperature of the desiccant/water system. It also increases as the
desiccant absorbs water (a dilute liquid desiccant will have a higher equilibrium vapour
pressure than a concentrated liquid desiccant). When the absolute humidity of air that has
come into equilibrium with a liquid desiccant of fixed concentration is plotted on a
psychometric chart, the equilibrium line closely follows a line of constant relative humidity
and the Fig1. illustrates this behaviour for solutions of lithium chloride.


As shown in the Fig 2., the brine-bulb temperature for a 43% solution of lithium chloride and
air at 30.0/25.6°C dry-bulb/wet-bulb will be 47.8°C. With an ambient wet-bulb temperature of
25.6°C, a typical cooling tower might supply water at29.4°C. It’s impractical to cool the
ambient air using this cooling water in a conventional heat exchanger, because the cooling
water is only one degree below the air temperature. However, a strong cooling effect could be
achieved by wetting the surfaces of the heat exchanger with the 43% lithium chloride. Of
course, one does not get this enhanced cooling for free. If the cooling process is to be
continuous, energy must be expended to regenerate the desiccant back to its original
concentration. If ambient air from the preceding example is brought into equilibrium with
43% lithium chloride at 85°F (29.4°C), the air will have a dew point of 33.5°F (0.8°C), a wetbulb
of 57.8°F (14.3°C), and its enthalpy will be reduced from 41.5 Btu/lb (96.3 kJ/kg) to
24.9 Btu/lb (57.8 kJ/kg). This large cooling effect, both in terms of latent cooling and total
cooling, and low dew point—both of which are achieved without a compressor—demonstrate
the potential for liquid desiccants to become an important part of HVAC systems. Liquid
desiccants have been successfully used to produce dry air for a surprisingly long time. Dr.
Russell Bichowsky, working for the Frigidaire Division of General Motors, first used
solutions of lithium chloride to dry air in the 1930s. Also in the 1930s, the Niagara Blower
Company introduced a liquid desiccant technology that used glycol solutions to prevent frost
from forming on low-temperature evaporators. Both lithium chloride and glycol continue to
be used today in liquid-desiccant dehumidifiers, but their use is limited primarily to industrial
applications[3].

3. Hybrid configuration: desiccant de-humidification and vapour compression based
cooling

An example of desiccant cooling application is represented in fig. 3 [4].


Figure 3.Schematic of Hybrid Liquid Desiccant aided Vapour compression air conditioning

Here, the cool strong desiccant solution is sprayed onto the top of the dehumidifier through
spraying nozzles. By gravitation, it trickles through the structure of the dehumidifier where it
gets contact with the process air stream blown perpendicularly to its trickling flow direction.
Since, the cool and strong desiccant solution vapour pressure is less than that of the air vapour
pressure, water vapour migrates from the air stream to the desiccant solution and condenses
therein. Consequently, the heat of condensation and mixing are liberated causing an increase
in the solution’s temperature. The process air stream is slightly cooled down due to its contact
with the cold desiccant solution. The dehumidified and rather warm process air stream then
passes successively through the evaporative cooler and the evaporator of the traditional
refrigerant vapour compression air conditioner, before being delivered into the conditioned
space. The diluted desiccant solution, exited from dehumidifier, is circulated through the
regenerator where it is heated and the moisture absorbed in the dehumidifier is now lost to the
scavenger air stream. In order for the system to keep functioning continuously and effectively,
an equal amount of water vapour absorbed from the humid air and condensed to the desiccant
solution in dehumidifier must be evaporated from the desiccant solution in the regenerator.
The hot and strong desiccant solution is thereafter cooled down in the pre-cooler and then
cooled further in the heat exchanger (HX) before being ready again to dehumidify the
incoming process air.

The lowest limit temperature attainable by the evaporative cooler is the process air wet bulb
temperature which decreases with the decrease of the relative humidity and increases with the
elevation of the dry bulb temperature. The essential role of the desiccant solution in this example is to lower the relative humidity of the incoming air stream in order to enable the
evaporative cooler to function more effectively.
Here, the desiccant assisted evaporative cooling is associated with the traditional vapour
compression air conditioning to reduce its size and enhance its coefficient of performance.
Because the latent load is handled independently by the desiccant dehumidifier, the need of
cooling the ventilation air below its dew point is obviated. The temperature of evaporation can
thus be lifted up to 15 °C from its generally practiced level of 5 °C for the traditional vapour
compression system. The increase in evaporation temperature will entail the increase of the
system’s coefficient of performance (COP).

This assemblage can be useful in humid climates where the wet bulb temperature is fairly
high. In such climates, a significantly downsized vapour compression air conditioner can be
supplemented with a desiccant assisted evaporative cooler in order to reach the desired indoor
temperature, thus enabling costs and energy savings and improving the indoor air quality.

4. Liquid desiccant materials

Liquid desiccants such as Glycols and solutions of halide salts are routinely used in industrial
de-humidifiers. Commonly used liquid desiccant materials include lithium chloride, lithium
bromide, calcium chloride, triethylene glycol and mixture of salts etc. The choice of desiccant
will have a profound effect on the design of desiccant de-humidifiers.

The desirable properties of liquid desiccants include large saturation absorption capacity, low
regeneration temperature, Low Viscosity, Good heat transfer, non volatile, non – corrosive,
odourless, non toxic, non flammable, stable and inexpensive. Surface Tension of liquid
desiccants is an important parameter of liquid desiccants as it plays important role in static
hold up and wetting of the surface of heat and mass exchanger of Liquid desiccant system.
Halide salts such as lithium chloride and lithium bromide are very strong desiccants. A
saturated solution of lithium bromide can dry air to 6% relative humidity and lithium chloride
to 15% but halide salts are corrosive in nature. Lithium Chloride has good desiccant
characteristics and does not vapourize at ambient conditions but droplet filters are necessary
to prevent any mixing of the liquid droplets with process air. Cost of halide salts are relatively
high except calcium chloride whose cost is comparatively low compared to LiCl, LiBr and
TEG. Another advantage of Calcium chloride is its low viscosity which reduces the pumping
power. But the CaCl2 salt is highly corrosive in nature and can be used in non metallic
systems only [5].

The least expensive alternative to lithium chloride is calcium chloride. Unfortunately, calcium
chloride is a relatively weak desiccant. A 42% solution, which is about as strong as can be
used without encountering crystallization, will dry air to about 35% rh. (For comparison, a
43% lithium chloride solution can dry air to a 15% rh.).

Glycols are the second class of liquid desiccants now used in industrial equipment. Both
triethylene and propylene glycol have low toxicity, and their compatibility with most metals
has led several researchers to use them in LDACs designed for HVAC applications. However,
all glycols have one undesirable characteristic that they are volatile and any evaporation into
the supply air makes it unacceptable for air conditioning for occupied buildings [6]. Salts of weak organic acids, such as potassium or sodium formate and acetate, have been explored as less corrosive alternatives to halide salts that are also not volatile. Although it is a significantly weaker desiccant than lithium bromide or lithium chloride, the ability to dry air below 30% relative humidity could make potassium formate a good alternative desiccant in some applications. Another less expensive alternative is potassium acetate. While potassium acetate could dry air to about 25%, its viscosity becomes very high. At 70% concentration and 27°C, a potassium acetate solution has a viscosity of about 28 cp. This is almost twice has high as a 43% lithium chloride solution at the same temperature. Water at 27°C has a viscosity of close to 1.0. [3].

Studies were also conducted on mixtures of calcium chloride and lithium chloride solutions to
take the advantage of good desiccant properties of LiCl and low cost CaCl2 [7].

4.1 Advantages of using liquid desiccants include

1. Lower air pressure drop in process air stream.
2. Liquid desiccants are capable of providing equivalent dehumidification as solid desiccant
systems with lower regeneration temperature(mostly 70 - 80°C) due to the internal cooling
provided by cooling tower water or chilled water and allowing utilization of solar heat or
waste heat.
3. Pumping of liquid desiccants is possible makes it possible to connect several small
desiccant dehumidifiers to a larger regeneration unit which is especially beneficial for
large multi zonal commercial buildings.
4. Liquid desiccants have high COP’s as highly efficient liquid-liquid exchangers could be
employed.
5. Simultaneous air dehumidification and desiccant regeneration is not necessary as it is
possible to store dilute saturate liquid until regeneration heat is available.
6. Liquid desiccants are highly beneficial for their ability to filter microbial contamination,
bacteria, viruses, and moulds from process air stream.

The Purpose of Using a Fresh Water Generator

While sea water is not edible or can be consumed in any appropriate way, many generators out there are rather helpful in the process of converting sea water into fresh water in a short period of time. The fresh water generator has managed to achieve a huge amount of attention from countless people from all over the globe. This is due to the fact that generators come in handy for many reasons, all of which are unique and what all individuals require in the first place. These are mainly used for the purpose of the conversion of sea water to fresh water.

Easy Installation
When it comes to the important matter of installation, a fresh water generator hardly takes up a lot of time. This means that people can have it installed without having to struggle too much in the matter, making it a great choice for the conversion of sea water to fresh water within a little amount of time. Usually these generators are not as huge as one may expect them to be, making them rather portable and easy to install due to their compact size that is most unlikely for a generator.

Less Maintenance Required 
What makes a fresh water generator worth its cost is the fact that it requires very low maintenance. While many people think that it is not simply true, these generators require no extra cleaning or an addition of other machines and equipment in order to run the generator on a daily basis in the future. Any ship crew or an individual on ships and boats can actually use it daily and save time on the low maintenance for this particular generator. The generator offers very easy access to anyone who wishes to use it. It does not require a good amount of maintenance for long periods of time.

Production of Low Salinity Water
The production of low salinity water is the result of using these generators; thus, those who are looking for acquiring this particular feature should definitely go for these generators as they can surely bring out their desired results in the near future. These generators are usually equipped with electric motors as well as water pumps, which come in handy in the job the machine has to carry out. Some of these generators also have steam heating systems built in inside them. The usage of these generators these days has already helped a great deal of people in the process of converting sea water into fresh water; and those who have not yet brought it should really do so now.

Cost Efficient 
The operational costs are also rather low in comparison and this makes it cost efficient. This is due to the fact that less fuel is used in the process of converting sea water to the fresh one. A fresh water generator is usually the kind of machinery which is used for a long period of time and even in short, it lasts for more than ten years. Different brands offer generators which are unique in their own way; therefore, the choice is completely up to people and they can always decide according to whatever they prefer more.

User-Friendly
A fresh water generator is something that everyone needs, especially for people who travel a lot and spend a lot of time on ships. The process of converting sea water to fresh water can be simply impossible and had it not been for these generators, people would still be looking for various other ways to carry out the task. These generators are easy to use on a day to day basis. This means that everyone can use it without having to have any prior technical knowledge. On the other hand, there is nothing difficult about these generators also because they are made for general use.

People can go here to read the new information about fresh water generator.

The Purpose of Using a Fin Tube

Amongst many other uses, a fin tube is also responsible for the transfer of heat and due to that these are being used for many top notch industrial applications in the present times. These are beneficial for anyone who wishes to indulge in the process of successful heat transfer through heat exchangers or other equipment. Here are different types of these tubes which are different in their own way and have various benefits that differ. Due to their high usage, these are available easily within the market at reasonable prices these days and interested buyers should invest in these for good.

Numerous Sizes
The fin tube is available in different sizes, all of which are different from one another. Choosing the best size may be difficult but the process can be made rather easy by selecting the size that is best for any task which a person is wants to complete in the long run. While the sizes range from short, medium and long, others sizes such as extremely short or extremely large ones can also be found without having to struggle too much. Since a lot of sizes of these tubes are currently being created, people can just go on and purchase whichever they prefer.

Rate of Conduction
The fin tube is known to be a high conductor of heat and because of its high conductivity, it is definitely recommended for all those people that require a smooth transfer of heat to take place on a day to day basis. Many other devices and equipment may have heat conductivity rate but none of them matches up to these tubes, which really do make them something worth it. On the other hand, these are also safe from any kind of corrosion that may occur in them in the long run. The high end resistance from corrosion also makes these tubes a great investment in the near future.

Steel & Carbon 
The fin tube has various types and these are made of different materials. The stainless steel and carbon steel tubes are amongst one of the highest sold ones due to the fact that they have a high heat rate in general. Metals are great conductors of heat, which is precisely why these materials of used while making these tubes to be used for high end industrial applications in the near future. The stainless and carbon steel tubes are both equally beneficial but individuals should always purchase the one which tends to fulfill their needs the most.

Other Special Materials
On the other hand, the other types of materials of a fin tube include copper as well as aluminum. These may not be as popular as the steel ones, but they are quite good on their own and still used for a wide variety of reasons. Aluminum and copper are great conductors of heat as well and this truly makes the transfer of heat easy and smooth with the help of these tubes. The best part is the fact that all of these materials used in these tubes make them different from each other, which makes it easy for people to pick out the best ones without having to waste too much time.

The Verdict
Apart from the kinds of these tubes, there are several types which are being used these days by many people. These are inclusive of welded, integral, plate and spiral fin tubes. The uses and benefits of all of these types are different from each other and choosing the best one solely depends on the requirements and needs of an individual. They are not exactly costly and have long-term durability which definitely makes them a high end investment that all individuals must do so as it offers so many benefits.

Reasons for Investing in a Steam Condenser

For those who are not aware, a steam condenser is used for a many different reasons and one of the most important ones includes the condensation of steam to water. These are used for other reasons too but majorly, they come in handy for condensing steam to water in the long run. The process may take up a lot of time but it is exceptionally effective and efficient. These are used by many high end industries as well as plants in the present times. Therefore, investing in these surely is the best way for anyone to convert condensed steam into water without having to face any issue. There are a number of reasons why people should – and are – investing in steam condensers and here are a few of them.

High End Affordability 
While these condensers may seem rather high end, their prices are not as much and these days, individuals can purchase these at reasonable prices. However, prices are always linked to the kind of condensers and that means their quality. Therefore, it is highly essential to be aware of the fact that a steam condenser is most likely to have a variable price range, all of which depends solely on the type and kind of the condenser. High quality ones are more towards the costly side and the average quality ones should be attainable for a fairly less price. The fact that it is so affordable has led many enthusiastic people to the shops to purchase the product. Most customers are impressed with the fact that it costs so less and yet is able to perform to such high standards. Better quality combines with high end affordability has really helped the product.

Easy to Install & Use 
The best part about setting up a steam condenser is the fact that it enables people to do any kind of installation. While a lot of equipment requires fixed installation, these condensers can be installed in a number of different ways which are all beneficial on their own. It all depends on either the requirement or the type of installation which is required by a person in the first place. These condensers can be installed both vertically as well as horizontally – choosing from both of these truly does depend on the person who is setting up these condensers for major applications of various kinds. It does not require hard labor to install the product and it also does not require experts to teach people how to use it. It is quite customer and user friendly in all senses of the word. It makes work simpler and easier to do.

Vast Variety
The condensation tends to take place in containers, which are all unique in their own way. Mostly, the containers are either shell shaped or tube-shaped, for that matter. A steam condenser can have any of these containers or chambers for the matter of condensing steam to water. However, everyone’s requirements tend to vary, which is why choosing the right chamber for the process is exceptionally important and should be thoroughly considered by an individual who is about to go ahead with the overall process of condensing heat to water. By choosing the right container, the procedure is most likely to go smoothly and be successful later on. There are a number of different options and varieties to choose from. Really, the customers can simply go crazy over the choice. It can be made using a number of different materials to suit each individual’s style or requirement as well.

So there it is, these are all the reasons why steam condensers are considered to be such industry winners and are selling like hot cakes in the markets. Go and buy one now!

Pros of Ultrasonic Cleaning

There are many cleaning techniques available in today’s world. However, most of those are not as effective as ultrasonic cleaning, whichis currentlyon the top of the list as it really is the most effective. It is considered to be one of the most efficient and effective types of cleaning that are available for everyone in the present times. With all of its short as well as long-term benefits, investing in it is something that all individuals must pay attention to in order to have any sort of cleaning down according to their needs. There is little doubt there is about the effectiveness as well as ease of usage of this exclusive method as it really has become one of the most famous ones these days.

Dirt & Grease Elimination 
Ultrasonic cleaning is something that removes all kinds of contaminants such as grease, oil, pigments, wax, dirt, dust and so many more. These are usually found on many items which are available within homes. Hence, the only proper and fast way for getting rid of these contaminants is to indulge in this cleaning as is truly does the work done swiftly and does not require many efforts in the process. In comparison with manual cleaning, this works best since the removal of such contaminants can otherwise be very difficult and sometimes, it can even be pretty much near impossible. However, with this sort of cleaning, it definitely can be taken care of. Usually, people will have to make an effort themselves by scrubbing hard for many an hour in order to get rid of the said grease. However, with ultrasonic cleaning, they will simply get over the task in a matter of minutes, at the most.

Saves Time
Through ultrasonic cleaning, cleaning off equipment as well as many other things has now become possible.
