Sentence examples for less refrigerant from inspiring English sources

As a results of tests, it was found that the performance was obtained in the heat pump unit using coil-2 design with less refrigerant circuit and a higher length of circuit with a superheat of around 6 K in both modes of operation.

Higher superheat or less system refrigerant charge could help mitigate the risk.

But, when using a less common refrigerant such as CO2, the designer faces new challenges.

In most applications it is a less expensive refrigerant than helium.

As the MR J T cryocooler uses a commercial scroll compressor developed for air-conditioning systems, compressor overheating due to the use of less optimized refrigerants may not be negligible, and could cause compressor malfunction due to burn-out of scroll tip seals.
