The general characteristics of an ice storage system have been studied and reported in this paper, together with the fundamental concepts behind the system which should be developed. Experiments were conducted on these concepts, and following results were obtained : (1) In the ice making process, uniform water temperature distribution appears in the storage tank when the water temperature drops below 4℃. (2) In the ice melting process, stored ice melts completely until the temperature of the water pumped up from the tank reaches the critical temperature θ_<LM>, which is the highest temperature usable for space cooling. This shows that the latent heat of stored ice can be used completely and effectively. (3) The amount of sensible heat which is pumped up and used effectively for space cooling is closely related to the Froude number Fr at the water inlet to the tank, critical temperatureθ_<LM>, and the" equivalent diameter of water inlet pipe, together with the method of controlling supplemental operation of heat pump.
