Abstract: R410A refrigerant, currently widely used in the heat pump system, is scheduled to be phased out. Based on the “drop in” refrigerant substitution technology, a new ternary environment-friendly mixture is developed. The comprehensive optimization work is done. The saturated vapor pressure...

R-454B is designed to be a drop-in replacement for R-410A in new systems, meaning that it can be used in equipment designed for R-410A with minimal modifications. This simplifies the transition for manufacturers and consumers. 4. Lower Refrigerant Charge: Similar to R-32, R-454B require...
摘要：An environmentally more benign refrigerant for replacing refrigerant R410A includes a majority portion of refrigerant R32 and a minority portion of refrigerant R134the volumetric capacity of the replacement refrigerant permitting it to be used as a near or exact drop-in replacement for ...
In addition，the environmental effect of direct emission before and after replacement of refrigerant was analyzed. The results show that the operating performance of the unit charged with refrigerant R452B was basically equivalent...
These experimental results will be useful for the HVAC community for facilitating the selection of the most promising candidates for drop-in replacement of R410A, R134a and R407C in residential heat pumps. 展开 会议名称: 17th International refrigeration and air conditioning conference at Purdue 2018...
