The condenser uses a refrigerant mixture produced on site and processed in a refrigeration loop (not shown). In the loop, the refrigerant mixture removes heat from the process in the condensers of the towers. It is then compressed, cooled, and throttled back to the initial pressure. The ...
Beijing 100835, China)Abstract: The performance of a new refrigerant, R1234yf/R134a (with a mass ratio of 89∶11), was studied as alternative to R134a in automotive air conditioning systems using micro-channel heat exchangers. The results show that the cooling capacity of R1234yf/R134a and...
