IIR documentSummary
This paper presents a theoretical model for a specific seasonal cold storage system with separate heat pipes. A quasi-steady state simulation model is established to analyze the charging performance of the system. The charging experiment has been carried out in Beijing to verify the theoretical model. The influences of various factors such as meteorological data, the length and radius of evaporating section and the fin coefficient of condenser section on the charging performance are analyzed with the model. It is shown that the atmosphere temperature is the most important factor affecting the charging capacity, the tube dimension of evaporator section should not be too long or too large, and the enhancement of heat transfer in condenser section is an effective way to increase the charging capacity of the cold storage system.
