404 Development of high efficiency heating tower

Abstract

Heating tower system, which is used for both cooling and heating by using water-cooled heat pump chiller, is not so widespread up to now because of the reasons as follows ; necessity of complex defroster, large space required for installation, and expensiveness. Therefore, we developed the compact and economical closed-type heating tower with the simple built-in defroster. The efficiency of the developed heating tower system is on the highest level in various air-conditioning methods.
