The High-Efficiency Ice-Storage Multi Air-Conditioner for New Refrigerant (R 407 C)

摘要

A new ice-storage multi air-conditioner, HiCOP-ICE 90, reduces integral power consumption thanks to HFC (R407C), whose an ozone destruction coefficient is zero. The air-conditioner uses are peak shaving pattern decreasing peak power consumption more than 90 percent in summer daytime. This pattern is typical of our firm's enterprising R&D techniques. This improved daily cooling COP 18 percent compared to the previous model. Hot water storage is added for winter to increase the heat pumps heating capacity. This paper reports features and techniques used to improve performances of the new air-conditioner.
