The refrigerant gas leakage through the radial clearance is one of the main sources of volumetric efficiency loss in rolling piston compressors. Therefore, the understanding of the flow characteristics through this clearance is essential in order to improve its volumetric efficiency. Although it seems ...
power. The refrigerant evaporates by absorbing heat from the outside air at8\deg C and transfers it to the house to maintain a constant temperature of25\deg C. Find a)Heat supplied to house b)MAX COP and actual COP

COOL COMFORT The race to find a replacement auto refrigerant heats up in Europe as a BAN ON HFC-134A looms 喜欢 0 阅读量: 14 作者: MARC S. REISCH 摘要: BECAUSE OF European Union (EU) regulations that will take effect in 2011, German carmakers will substitute carbon dioxide for the ...
The EPA, MACS and SAE all say that the only acceptable replacement refrigerant for newer R-134a system is R-134a. Nothing else should be used to avoid cross-contamination problems and cooling performance issues. Older vehicles with R-12 can be retrofitted with R-134a or other approved ...
As a result, a number of alternative refrigerants including HFC-134a have emerged as promising chlorine free alternatives to CFC-12 in domestic refrigerators and freezers. The proper size of a capillary tube with a new refrigerant is a critical factor for the optimum performance of a refrigeration...
thanks to its straightforward design and compatibility with the R134a refrigerant system. The connector's interchange part number, R134a, ensures that it is a perfect match for your vehicle's existing AC components. Its placement on the vehicle's air conditioning system is crucial for maintaining...
