AN EXAMINATION ON ADEQUATE CAPACITY FOR MULTI-SPLIT TYPE AIR CONDITIONING USING CENTRALIZED CONTROLLER WITH A FUNCTION OF GAS RATE PROPORTIONAL DIVISION

Abstract

This paper discusses about an examination on adequate capacity for multi-sprit type air conditioner using centralized controller with a function of gas rate proportional division. The objective system is a gas heat pump air-conditioner of an agricultural research building. The effect of energy saving was analyzed by LCEM tool using the estimated actual thermal load under the assumption of retrofit / renewal for air-conditioning equipment. The energy savings from the current situation was that the case of proper capacity repair is 5% reduction, and the case of renewal can be reduced 15% of the operation energy consumption.
