Abstract

In the age of global warming, energy saving features and overall reduction of environmental impact are critical components that must be addressed when developing new HVAC units. We chose the R32 refrigerant, with its lower LCCP as a more sustainable choice than the R410A. However, R32 has its drawbacks. Due to its smaller molecular weight, internal leakage loss is higher for the R32. Moreover, high discharge gas temperature decrease the reliability of the compressor, and make a large overheating loss increase. In this study, we will describe the technologies that were developed to overcome these drawbacks. We will also present the performance and reliability of the newly developed high efficiency swing compressor series for R32 refrigerants.
