The oil-free VCR system consisting of oil-free linear compressors, an off-the-shelf condenser and an evaporator with an electric heater avoids the impact of oil lubricant on the heat transfer so that the two refrigerants can be appropriately compared with each other. Experiments for two ...
5. 5 electronic scales for the weight measurement of R134a Tank, R1234yf Tank, PAG oil,POE oil, used oil; 6.Benefit from the deep recovery program, recovery efficiency is up to 95%; 7.HP/LP/HP+LP charge mode is selectable;
This study was to compare the performance characteristics of refrigeration system using R134a and R1234yf in a refrigeration truck. When the refrigerant charging amounts increased from 1.1 to 1.4 kg, COP of R134a system was increased and the maximum COP was 2.63 at the charge of 1.4 kg. ...
Brazed-plate heat exchangers reduce system volume and refrigerant charge. The present invention further relates to a process for producing cooling comprising evaporating the compositions of the present invention in the vicinity of a body to be cooled, and thereafter condensing said compositions. The ...
