The desiccant air conditoning system

The desiccant air conditioning sytem shows a very high energy efficiency

Desiccant air conditioning system is the energy-saving air conditioning system by controlling the temperature and the humidity separatly.

In the conventional air conditioning system using the refrigerator and the cold water, the system has the method which reheat after super cooling to lower the humidity.

But in this method, the system consumes the wasted energy and the system cannot respond to changes the outside air flexibly.

The desiccant air conditioning sytenm has the method which is removing the moisture in the air by the defumidification rotor, and this system shows a very high energy efficiency.

And the system responds flexibly to changes the outside air conditions and can contorols appropriately the inside air.

For that reason, it is best applied to a space that requires a large amount of outside air or a space that requires dehumidification management.

Feature of the desiccan air conditoning system regenerated at low temparatures

Do not use the energy of super cooling and reheat for dehumidification.
Since it is dry air after dehumidification, it is comfortable even if the cooling setting temperature is high.
Suppress indoor pollutants such as mold for 100% ventilation (air supply volume = exhaust volume)
Reduce the cost of the combined air conditioning equipment
Use the exhaust heat at low temperature(50～60℃) as a heat source for regeneration of the dehumidifying rotor, which was a problem of the conventional system.
. Achieves non-fluorocarbon air conditioning without using refrigerant.

We propose the best type according to the environment, such as the dehumidification requirements and the availability of exhaust heat.

We can incorporate "the Mega cool" in "the desiccant air conditioner"

Effect of the desiccant air conditionin

The moisture removal rate of the high efficiency desiccant air conditioner is four times that of the conventional air conditioner.

By using the desiccant air conditioner together, the operating efficiency of the other air conditioning system can be improved. Therefore, it contributes to the reduction of the required refrigeration capacity and energy costs.

In addition, the desiccant air conditioner dehumidified by the desiccant is non-fluorocarbon type that does not use refrigerant. Therefore, it is an earth-friendly system.

As hot water, heat pump exhaust heat and natural energy are used as heat sources (Regenerative heat source temperature:50～60℃) for regeneration of the dehumidification rotor, it contributes to CO2 emission control.

Principle of the desiccant

Traditional desiccant air conditioning units used the heating source from electric heat, steam, direct gas combustion, hot water boiler, etc. in order for desorption (recycling) of the moisture attached to the dehumidification rotor. The heating pump and desiccant air conditioning units that our company have developed utilizes the ultra low temperature recycling dehumidification rotor that have been newly developed at our company. This ultra low temperature recycling dehumidification rotor is possible to recycle at 113ﾟＦ of warm air. That is how the ondenser exhaust heat (condensed exhaust heat) of the compressor is able to be recycled and used. 　Since food supermarkets utilize refrigerator units for display cases, the exhaust heat from this refrigerator unit can be effectively used, and greatly lower the running costs.

Difference from conventional cooling method

Humidity control is the focal point behind saving energy in air conditioners.

In a traditional air conditioning systems utilizing refrigerators or cold water, in order to lower humidity after chilling the air, a method to re-heat to the specified temperature was employed.

However, in addition to this method wasting energy, it was not flexible in supporting outside conditions.

In contrast, a desiccant air conditioning system, which can separately control temperature and humidity, exhibits incredibly high energy-efficiency by employing a method to chill to a specified temperature by directly removing the moisture in the air using a dehumidifying rotor coated with desiccant, and afterwards exchanging heat by using a sensible heat rotor.

In addition, due to being flexible in accommodating to any changes in outside conditions and appropriately control the internal air, it is optimal for any environments that require large-volume incorporation of outside air or strict dehumidification controls.
