Tokyo Gas Company, together with Mayekawa Manufacturing Company, and Waseda University, has developed a gas driven hybrid air conditioning system that utilises a natural refrigerant (ammonia and water), and features prevention of both ozone layer damage and global warming, and whose gas consumption is reduced by 45% compared with conventional counterparts.
The cooling capacity has an energy coefficient of performance rating of COP 2. (COP is defined as the ratio of input energy to output energy and represents the heating or cooling capacities per unit consumption of gas or electricity). It indicates the calorific ratio with respect to volume energy input into a chiller or ...
