| Abstract: | 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. |
