Recently large capacity of electric equipment and increasing in atomic power generation are shown. One of the reason is shortage of the electric power supply for air conditioning load during summer. And every consumer is concerning about economical refrigeration and air conditioning system to decreases electric power consumption and decrease in global warming. For these necessities, ice making thermal storage system is required. Therefore, in this paper, the possibility of continuous slurry ice making using flowing organic water solution in cooled circular tube has been investigated. The experiments was carried out under some parameters of concentration and velocity of water solution, temperature of cooled tube wall, and control pressure in tube, As a result, four types of operating conditions in the pipe, that was supercooling, continuous ice making, intermittent ice making and ice blockage, were classified . And it was found that the critical condition for continuous ice making was acquired as a function of these experimental parameters.

In the present study, the possibility of continuous slurry ice making using flowing water solution in a cooled tube has been investigated. The experiments were carried out at various concentration and velocity of water solution, temperature of cooled tube wall, and control pressure in a tube. As a result, four types of operating conditions, that is super-cooling, continuous ice making, intermittent ice making and ice blockage, were classified. And it was found that the critical condition for the continuous ice making was acquired as a function of these experimental parameters.
