Below is the article with translation titled, “DEHUMIDIFYING, AIR CONDITIONING BY EVAPORATION HALF THE RUNNING COST OF AIR-CONDITIONING THREE VENTURE BUSINESS OF JAPAN AND THE U.S.”

Three venture businesses of Japan and the U.S. have jointly developed the dehumidifying cooling system. The air goes through the layers of water saturated paper to be cooled by evaporation. Efficiency rate to be heightened when the air is dehumidified first. No refrigerant and compressor is needed, the cooling cost would be cut in half of the conventional air conditioning.

The equipment is developed by Earth Clean Tohoku, the air conditioning units venture (President Kenichi Konno, Sendai city), Idalex, the U.S. engineering co. (Denver, Colorado), and Novel Air, the dehumidifier equipment manufacturer (Louisiana, New Orleans). It is named ‘Megacool’ and will be introduced on 26th at the U.S. Academy of Heating, Air-Conditioning and Refrigeration planned to be held in Chicago.

It is equipped with the multiple layered filter made of special paper coated with plastic. The air temperature is to be reduced while going through the filter with the effect of evaporation. However the Japanese humidity is so dense that enough reduction of heat cannot be expected only by evaporation. So they set the dehumidifier up front to utilize the maximum effect of evaporation. 40C can be cooled down to 12C.

In case of a factory to cool the 10,000 m3 air for an hour in the mid summer heat in Tokyo, it costs 17,000 yen for a day (10 hours) for its running cost of conventional absorption type of freezing equipment, while 8,000 yen (47% less) with this newly developed cooling system.
