Storage technology has the advantage to solve the problem of the not matching in time and space of energy's supply and demand, making it an effective way to the rational use of resources and reducing environmental pollution. What is used in this paper is a regular flat phase change heat storage module packaging with capillary network and phase change material. In this paper, the software Fluent was used to simulate the impact factors and the ways to enhance heat transfer in the process of phase change. The simulation result indicates that: 
During the melting process, because of the influence of natural convection, the top of phase change regional melts faster, the temperature contour ramp to top. The higher the horizon is, the temperature contour is more stable. Natural convection play different role in the melting and solidification process, which accelerated melting rate in the melting process, and slowed down in solidification. The surface temperature of phase change thermal storage panel will be maintained at 26.5°C, within the limits of human body comfort and is able to improve the air temperature within a certain space.
