Abstract
Vapor compression refrigeration system (VCRS) is a cooling system that has high COP and high cooling capacity. The research emphasizes on the characteristics of a miniature VCRS and how the experimental factors affect it. This research can be divided into two parts: steady state experiments and VCRS simulations. In steady state experiments, a VCRS has been designed and assembled. The whole system is about 6 kg weight, and the size of the system is about 160?350?150 mm3. Experimental investigations are conducted to analyze that how the orifice of the expansion valve, heating watt and the rotational speed of the compressor affect the system performances. The results show that the system has a maximum cooling capacity 150W, and the COP of the system varies from 1.36 to 4.25. In VCRS simulation, a program is written to analyze and predict its performances. The program is used to analyze that how the size of the condenser and the evaporator influences the system performances. The errors of the simulations are less than 10%.
