Volumetric Refrigeration Capacity

A Natural Refrigeration System For Supermarkets Using CO 2 As ...
R-744 systems have a high volumetric refrigeration capacity, as a result of their very high vapour density when compared to other refrigerants. As a consequence, refrigeration compressors using R-744 are 6-8 times smaller than those of R22 ... Content Retrieval

POSSIBILITY TO INTORODUCE HFO-1234ze(E) AND ITS MIXTURE WITH ...
But its volumetric refrigeration capacity is quite low. As adding HFC-32 as the second component into HFO-1234ze(E) in order to make the mixture of HFC-1234ze(E) and HFC-32, the volumetric refrigeration capacity is improved with keeping the COP value higher than that of R410A. ... Fetch Doc
