摘要
PURPOSE: Provided is a phase change temperature controlling thermal energy storage system for heating hypocaust and greenhouse. CONSTITUTION: In the thermal energy storage system, 5-15 wt% of urea or glycerol is added to typical phase change material(PCM) having a physical property stabilized by adding a nucleating agent(Na4P2O710H2O) and a thickener(CMC-Na) to CH3COONa 3H2O; heated to 65 deg.C and homogeneously mixed with mixer for 2 hours to control a phase change temperature. Thereafter, the phase change material is liquefied and injected into tube(1) having a flexible structure. And then, the tube is sealed and vacuumized to buffer an expansion pressure of the PCM.
