An Experimental Study on an Ice Storage System by a Two-Phase Closed Thermosyphon

2상 밀폐 서모사이폰을 이용한 빙축열 시스템의 성능

A two-phase closed thermosyphon is applied to an ice storage system. The thermosyphon is used to freeze the water in a storage tank. The experiment has been performed to investigate the effects of the important parameters such as the quantity of the fluid filled with, the ratio of the length of the evaporator to the condenser, and the temperature and the mass flow rate of the brine. It is found that the higher thermal performance of the thermosyphon is obtained as the ratio of the length of the evaporator section to that of the condenser section is decreased and the temperature of the brine is lowered. The increase of the quantity of the working fluid also favors the performance of the system. The experimental data can be utilized for the basic design of ice storage systems with thermosyphons.
