Summary

A new type of ice-on-coil system is proposed, which consists of a water tank, coils located above the tank, an upper water distributor, and a circulating water pump. Based on numerical analyses using simple models, the estimated characteristics of the new system are as follows: 1) filled water volume can be reduced and consequently the rates increase of water cooling and subsequent ice making; 2) leaving water temperature is kept stably at 0 deg C even at high heat loads, as long as ice remains; 3) the COP is improved in compressor aided operation; 4) agitators are not employed and hence the additional power and heat gain due to agitation are eliminated; 5) ice quantity can be detected more accurately by measuring water level.
