摘要
高温热泵可以有效回收工业余热,达到节能减排和保护环境的目的。目前,有关高温热泵技术的研究热点在于寻找一种全球变暖潜能值(GWP)低、使用性能良好的工质,以替代现有CFC-114、HFC-245fa工质。对新型环境友好型工质HFO-1234ze(Z)进行了综述,其GWP<1,临界温度高于423K,是一种潜在的高温热泵替代工质。总结了近年来国内外学者对HFO-1234ze(Z)的合成技术、热力学性质、输运性质、传热性能等方面的研究,并分析了HFO-1234ze(Z)在高温热泵系统中应用的可行性,认为HFO-1234ze(Z)在高温热泵中具有较好的工作性能和发展前景。
High temperature heat pump can effectively recover industrial waste heat to achieve the purpose of energy saving,emission reduction and environmental protection.At present,novel working fluids for the high temperature heat pumps are studied to replace CFC-114 and HFC-245fa.The alternative working fluid should have low global warming potential(GWP)and good working performance.The eco-friendly working fluid HFO-1234ze(Z),whose GWP<1 and critical temperature above 423 K,is considered as a potential heat pump replacement working fluid.This paper summarizes the research of HFO-1234ze(Z)including the synthesis technology,thermophysical properties,transport properties,and heat transfer performance.The feasibility of application of HFO-1234ze(Z)in high temperature heat pump system is analyzed.It is considered that HFO-1234ze(Z)has good performance and development prospect in high temperature heat pump.
