The PSH compressor with vapor Injection is a R454B optimized dedicated heat pump compressor with higher allowable discharge gas temperature limits. It is also multi-refrigerant qualified for R410A and R454B and simplifies the transition to R454B, which has a lower global warming potential. It is designed for medium and high-temperature applications (up to 65ºC) and low ambient operation. A large range of compressor capacities are available from 7.5-40 tons of refrigeration and individual compressors can be manifolded together to further increase system capacity.
To continue the increase of the market transition into heat pumps and extend the use into colder climates, the PSH compressor combines the ability to use both liquid and vapor injection in the same product. Tandems and trios can also be used with a single economizer heat exchanger which simplifies t The product has been designed with simplicity in mind; the same compressor can be used for both R410A and R454B and in both liquid and vapor injection operating modes. It can be manifolded and used with a single economizer heat exchanger. There is a wide capacity range available from 7.5 to 40 tons of refrigeration with larger capacities possible in manifolded configurations.
It is available in all required voltages and frequencies which allows it to be used both in the United States and globally. The PSH compressor with vapor and liquid injection can be used in heat pumps in mild climate zones to areas where very cold climates are normal and expected. Increasing this operating range, will further drive the market adoption of heat pumps and decrease the need to burn fossil fuels for heating.
