Scientists in China have developed a PV-driven direct-drive refrigeration system for electronic device cooling. The proposed system has so far provided low exergy levels, but its costs are much lower ...

Dimethyl ether (DME) and its blend of refrigerants (R429A, R435A, and R510A) are considered in this study's second law analysis as potential replacements for R134a. The performance of various ...

As the heart of a refrigeration system, the compressor is a vapor pump that creates the system’s required pressure differences between the low and high sides of the system. In addition, it raises the ...

A large percentage of compressor failures in low-temperature vapor-compression refrigeration system applications originate from overheating. Typical compressor capacity rating data is based on an ...

Vapor compression cycles are predominantly used in air-conditioning, heat pump and refrigeration equipment. A good understanding of transient behaviors of vapor compression systems is critical to ...
