跨临界CO2热泵系统性能的试验性研究
Experimental Research of Trans-critical CO2 Heat Pump System Performance
摘要
Abstract
In order to promote the efficiency of trans-critical CO2 heat pump water heater,by building a trans-critical CO2 heat pump system experimental units,to study its performance and find its operating regular pattern. The results show that:when the termination temperature of water is constant, the heat of cooling water absorbs from the gas cooler increases first and then reduce as the high-pressure in an evaporation temperature; the COP of system exsists a maximum value, that is , there is an optimal high-pressure Popt; and the COP of system rises with evaporation temperature going up; after replacing the tube with spiral in inner tube of coaxial heat exchanger,the system works more stable and COP has been improved.关键词
