Experimental Research on the Heat Storage and Discharge Performance of a New Phase Change Material

摘要

The heat storage and discharge performance of a heat storage tank filled with a new phase change material (PCM) SXR-S was studied based on various working conditions, especially on different inlet water temperatures and velocities. The experimental results indicate that the heat storage and discharge process of the heat storage tank with twin involutes configuration are steady-going and symmetrical, and that the speed of heat storage and discharge will be changed by altering the inlet water temperature and velocity On the occasion of heat storage, the higher the inlet water temperature and the greater the speed of flow is, the shorter the process of heat storage is, contrarily longer; and on the occasion of heat discharge, the lower the inlet water temperature and greater the speed of flow is, the shorter the process of heat discharge is, contrarily longer.
