摘要
Abstract
Built a test platform using injection bypass of sub-cooler to study the influence of injection volume on heating thermodynamic characteristics.The test results show that as the injection volume gradually increases,the exhaust temperature of the compressor also decreases,which can ensure the stable operation of the unit in cold regions;when the outdoor temperature is lower than 0℃,the outlet temperature and inlet temperature of the auxiliary road are comparable,the heating capacity and energy efficiency of the unit are the largest,and as the injection amount increases further,the heating capacity and energy efficiency of the unit begin to decrease;when the outdoor temperature is higher than 0℃,when the injection amount is"0",the heating capacity and energy efficiency of the unit are the largest.关键词
