A Review of Desiccant Dehumidification Technology. Ahmad A. Pesaran. National Renewable Energy Laboratory.

Prepared for Proceedings of EPRI’s Electric Dehumidification: Energy Efficient Humidity Control for Commercial and Institutional Buildings Conference, New Orleans, Louisiana JuneNational Renewable Energy Laboratory. Handbook of Dehumidification Technology is a handbook of dehumidifiers and how they work.

This manual describes the principles of dehumidification and looks at the domestic and industrial applications of dehumidifiers, along with design considerations for refrigerant dehumidifiers. desiccant to the regeneration air. When the RH of the process air is high, the desiccant can adsorb more moisture from that air stream.

Maintaining an adequate difference between the relative humidities of the process and regeneration air streams is essential to dehumidify effectively using a desiccant wheel.

Note: Total-energy wheels, alsoFile Size: KB. The desiccant dehumidifier was is used to improve the energy efficiency. It is demonstrated that the liquid desiccant-based dryer is techno-economically superior.

The development of an. This article represents a broad perspective in this regard; moreover, by identifying the near-term development goals, it portrays an image Development of an energy efficient desiccant dehumidifier book the next generation desiccant technology that will be capable of handling the hourly variation of cooling load in NZEB in an energy efficient manner.

Figure 1 Two-stage desiccant dehumidification HVAC system for office buildings and shopping centers In actual commercial and institutional applications designed by the author, the energy efficiency of desiccant regeneration has been improved significantly in two ways.

resulting in cost-effective desiccant systems for commer­ cial buildings 1. It was feasible to reduce the energy consumption for this pilot building by 63% compared to a reference building (Fig. 4(b)) after installing Development of an energy efficient desiccant dehumidifier book energy efficient technologies along with the desiccant dehumidifier.

Thus, it is obvious that if a desiccant dehumidifier is installed, it can certainly play a vital role in the energy saving. Munters energy efficient technique - your guarantee The rotating heart of Munters dehumidifiers Energy recovery sectors for enhanced performance available - saving up to 30% energy How the desiccant wheel works The Munters desiccant wheel works on the principle of sorption, which is the adsorption or the absorption process by which a desiccant.

If thermal energy is cheap and power costs are high, a desiccant system will be most economical to remove the bulk of the moisture from the air.

If power is expensive and thermal energy reactivation is costly, a refrigeration system is the most efficient choice. energy efficiency of dehumidifiers. Passive desiccant dehumidifiers aren't really meant for large areas - the E looks like it is sized for a closet ( sq. ft). The Most Energy Efficient Dehumidifiers.

Considering everything we’ve discussed so far (tested power draw, tested moisture removal rate, the fact that higher capacity models are generally more energy efficient than lower capacity units, etc.), the three best most energy efficient dehumidifiers.

The paper describes the development of a hybrid solution that improves air dehumidification. It comprises the integration of a composite desiccant and a nano-woven membrane for air dehumidifcation.

The solution compliments any building HVAC project where the removing moisture from the air via an energy-efficient means is a concern. When the weak desiccant leaves the dehumidifier soaked with water, it moves to the regenerator to be reactivated.

Inside the regenerator, hot air is made in contact with the weak solution, it. A desiccant dehumidifier currently under development could be what the nation’s comfort-seeking homeowners want as they address their indoor air-quality issues.

The DD G hangs out of the way in the basement, comfort-ably warding-off air-borne critters that thrive on humidity. Narayanan, in Clean Energy for Sustainable Development, Desiccant Wheel. A desiccant wheel is a common type of sorption dehumidifier using a solid desiccant.

It is also known as a rotary dehumidifier. The desiccant material is coated, impregnated, or formed in. However, you need to know that energy efficiency and ability don’t often go hand in hand.

Thermo-electric types are among the most cost-effective models but don’t compare to compressor types in terms of moisture removal. Desiccant dehumidifiers are quite energy efficient but fall behind the others in their humidity control abilities.

Desiccant dehumidifiers. We have over 20 years of experience of building and manufacture of industrial dehumidifiers. In all of the industries they control dew point and relative desiccant dehumidifiers are of the highest quality to be found anywhere in the world.

Figure ES Part load efficiency degradation for a ducted dehumidifier (left) and standalone dehumidifier (right) under two cycling scenarios. Both standalone dehumidifiers operated the fan for 3 minutes after the compressor turned off, which resulted in significant latent degradation.

Testing indicated that up to 42% of the moisture. Building for Energy Efficiency, Asian Institute of Technology & Energy Policy and Planning Office, Bangkok, Thailand. Development of Solar Desiccant Dehumidifier Jan Desiccant dehumidifiers can maintain indoor humidity levels between 40 percent and 50 percent, creating a healthier indoor weather, saving energy while improving comfort.

Saving energy saves you money The tips in this book can help you find energy saving opportunities around your home, along with over $ in coupons for energy-efficient. Desiccant dehumidifier versus compressor dehumidifier. If you need to control basement humidity, a desiccant dehumidifier is a good choice.

Desiccant dehumidifiers use a desiccant wheel to remove moisture, rather like the way silica gel keeps food items moisture-free. A built-in heater restores the wheel’s ability to absorb moisture.

air (i.e. liquid desiccant regeneration), and changes back to strong solution. The performance of the dehumidifier directly determines the efficiency of humidity control of THIC system.

And, the liquid desiccant regeneration is an energy-intensive process, which requires external energy sources to heat the weak solution and it is the most. Having a library dehumidifier permanently in place will be one of the most cost-effective and efficient methods to control excessive airborne water vapor.

There are many different models that are well suited for this such as the Phoenix and also the Phoenix D which are portable units. liquid desiccant cooling systems have been developed to dry and cool air that has a large latent load using a more energy-efficient approach.

Taking advantage of the high affinity for water of desiccant solutions, liquid desiccant systems can dehumidify air without cooling it to the dew point temperature. Desiccant dehumidifier is most accepted system across industries for ensuring required humidity conditions.

It is one of the most energy friendly methods of dehumidification. A desiccant dehumidifier has added advantage, it can function equally well at extremely low to very high levels of humidity without regeneration problems and no changes in.

The Commercial Dehumidifier is an ultra-efficient dehumidification system that combines the benefits of desiccant dehumidification and mechanical cooling.

The system design permits the capture of condenser heat (normally rejected as waste) to power desiccant dehumidification. The Dehumidifier units provide low dew point air at space-neutral dry-bulb temperature. 2 days ago  Energy-star rated dehumidifiers will go easy on electricity/power consumption – little to no impact on your utility bills.

The hidden adequacy of the DivinAir Portable dehumidifier truly comes down to the desiccant material that absorbs excess water and dampness in any case.

These % chemical-free, totally taste and odorless free, and ensured to be non-toxic and safe desiccant “beads” work to pull up dampness directly from the air a space. The difference in the costs of electrical power and thermal energy (i.e. natural gas or steam) will determine the ideal mix of desiccant to refrigeration-based dehumidification in a given application.

If thermal energy is cheap and power costs are high, a desiccant based system will be most economical to remove the bulk of the moisture from the. Dehumidifiers are a great way to remove odors, dust, allergens and humidity from the air in your home, but if you’re not careful with your purchase, they can be a real strain on your wallet and the environment.
