Experimental Investigation and The Development of Phase Change Heat Storage Device Adapted to The Solar Energy Heat Pump

摘要

on the basis of the working principle of solar heat pump system is introduced in this paper. Focuses on the structure of the heat storage device and the selection of phase change materials, structure, The influence of phase change materials the size of the diameter to heat-exchange, The influence of phase change materials piled up form to heat-exchange, The influence of thermal fluid flow velocity to heat exchange , In-depth analysis of phase change materials and thermal fluid accumulation of heat and heat release process , Solve the problem of supercooling and dialysis of phase change heat storage materials. The use of phase change have a positive reference value.
