Thermodynamic Analysis of a Two Stage Vapour Compression Refrigeration System Utilizing the Waste Heat of the Intercooler for Water Heating

[摘要] This article focuses on the various aspect of use of waste heat from intercooler of a multi-stage vapor compression refrigeration system using ammonia as a refrigerant. Energy and exergy analysis of the multi- stage refrigeration system having an intercooler is performed. The COP of such a system is found to be increased by 4 to 5%, and calculated to be approximately 3.24. Heat recovery through the intercooler proved to be beneficial as the COP of the system is improved along with heat recovery of 20 kJ/s. The analysis can represent a physical system where water can be heated through the heat extracted from the intercooler.
