The world’s first, Development and sales of the Liquid Based Humidity
Controlling Air Conditioning Unit for adopted Ionic Liquid in the Humidity Control
Agent～Achieve energy savings air conditioning for hospitals and factories～
Chubu Electric Power Co., Inc. (Headquarters: Higashi-ku, Nagoya-shi; President &Director: Satoru Katsuno) and Dyna-Air Co., Ltd.(Headquarters: Chiyoda-ku, Tokyo;
Representative Director & President: Hikoo Miyauchi; hereafter, “Dyna-Air”) havedeveloped the liquid type humidity controlling air conditioning unit “Moist Processor”(hereafter, “developed product”) adopted ionic liquid for the humidity control agent for thefirst time in the world. Our company and Chubu Electric Power Co., Inc. will start selling.
Both companies have already developed a new technology that utilizes ionic liquid as thehumidity control agent in the liquid type humidity controlling air conditioning unit realizing highenergy savings at low cost for the first time in the world, in September 2018.
The newly developed product has reduced the manufacturing cost by about 20% and theinstallation area by about 25% compared to the conventional model. We have also succeeded insignificantly reducing the amount of humidity control agent used, and the power consumption of
the humidity control agent circulation pump has been reduced by about 90%.Furthermore, wehave confirmed the same sterilization performance as the conventional machine.
The liquid type humidity controlling air conditioning unit can not only either dehumidify
and cool or humidify and warm at the same time but also can purify outside air so it has
been introduced primarily in hospitals and in food factories. The agent is circulated
between the outside air processing unit and the regeneration unit where the temperatureand concentration is adjusted so that air with the appropriate temperature and humidity
can be supplied to buildings.
In the future, we will help reducing the cost of introducing air conditioning equipment,
solving hygiene issues, and saving space and energy mainly in hospitals and foodfactories by proposing developed products.

【Features of the developed product】
1 Adopting ionic liquid for the humidity control agent（The world’s first）
By using a liquid that does not easily dissolve metals for the humidity control agent, themanufacturing cost can be reduced approximately 20% compare to conventional products
because general purpose metal (iron, stainless steel, aluminum, etc.) can be used.
In addition, installation area is reduced by approximately 25% by adopting a newly developed
heat exchanger.

High energy efficiency
Power consumption of humidity control agent circulation pump has reduced
approximately 90% compared to conventional products by reducing the amount ofhumidity control agent.
3 Integration of developed liquid desiccant module into AHU
By modularizing the humidity control unit of the developed product and incorporating it
inside air handling units (AHU) used for general building air conditioning, it is possible torespond to a wide range of air conditioning conditions (air volume, capacity, etc.) according
to customer needs. (Refer to figure3)
