Experimental Study on Heat Storage and Release of the Phase Change Thermal Energy Storage Unit with Bushings between Double Flow

Abstract:

The phase change thermal storage unit With Bushings Between Double Flow was proposed through adopting a kind of new phase change material (PCM), JDJN-60. In addition, the corresponding heating experimental device was built. The study with regard to the heat storage characteristic of JDJN-60 was performed. The results show that the thermal energy storage process has three stages and there is a certain undercooling of the PCM. The effects of natural convection on the heat storage and release process are different. The natural convection accelerates the liquefaction process and alleviates the solidification process.
