Abstract
According to the popularization of air conditioners, maximum power consumption in summer is increasing year by year. Ice thermal storage system is expected to level the "maxmums". SANYO Electric Air Conditioning Co., Ltd. And Tokyo Electric Power Company cooperatively developed ice thermal storage commercial air conditioning system ECO ice mini "ECO mini guppy". The feature of the system is integrated outdoor unit which conventional outdoor unit and thermal storage tank are combined into one unit. Since the unit was improved, it is as easy as ordinary commercial air conditioner in installing the unit. By using new refrigerant R410A, the unit is environmental friendly. Comparing with non-ice thermal storage system, the unit is energy-saving and can decrease about 35% of rated power consumption in cooling operation.
