Résumé

By recent interest in overcoming the heat transfer limitations of phase change materials (PCMs), thermal energy storage process that enhanced by embedded heat pipes has received much attention. Due to coupling with heat pipes, the phase change process of PCMs can be indicated or controlled by the operating conditions of heat pipes. In the present paper, a vacuum insulated cold thermal energy storage panel that embedded with heat pipes and PCMs are investigated experimentally. The evaporator section of heat pipes is exposed in air. By applying different air speed and air temperature, melting process of PCM and air temperature difference through the evaporator section of heat pipes are analysed, so as to help to indicate the amount of cold thermal energy in the panel in real time. The study also provides a framework for designing of portable cold thermal energy storage device with controllable energy supply.
