PSH compressor a “game-changer” for heat pumps
28th February 2024
USA: The new Danfoss PSH scroll compressor with vapour injection allows for a wider range of operating temperatures and could be a potential “game-changer” for heat pump adoption.
Its ability to operate in a wider range of ambient temperatures allows for an effective and efficient heat pump in colder climates, Danfoss says.
An R454B optimised dedicated heat pump compressor with higher allowable discharge gas temperature limits, the PSH 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 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 economiser heat exchanger which simplifies the system design and offers greater flexibility. The same compressor can be used for both R410A and R454B and in both liquid and vapour injection operating modes.
It is available in all required voltages and frequencies, which allows it to be used both in the United States and globally.
