Abstract

Aiming at the problems of insufficient utilization of cooling capacity and low ice making efficiency in the ice making process of small household ice maker, a new type of water tank was designed by calculating and analyzing the cooling capacity in the ice making process of ice maker. Simulate the ice making process with software AnsysFluent, compare the ice production of ice maker with new and original water tank in the same time, and carry out experimental verification. The simulation result shows that 75.68% of the cooling capacity is wasted in the original water tank, and only 28.85% in the new water tank when ice making time is 9 mins. At the same time, the cold energy consumption in the new water tank is 43.34% lower than that of the original water tank, and the ice production is increased by 65.22%. The experiment result shows that the ice production of ice maker with the new water tank is increased by more than 75% when ice making time is between 8 and 10 mins; the ice production of ice maker with the new water tank is increased by more than 35% when ice making time is between 11 and 12 mins, and the optimization effect is obvious.
