Heat pumps

Full range of injection capabilities enables electrification in HVAC 

The Danfoss variable speed scroll compressor range is expanding to include the ability to operate with vapor, liquid, and wet injection. The upcoming injection technology in the Danfoss VZH compressor range will accelerate the flexibility for manufacturers to design units that achieve superior performance in comfort control, cooling, and low ambient heating for cold climates. Used alongside the Danfoss fixed speed compressor range, and combined with the full Danfoss qualified injection package, it is truly a full system solution. 

Breakthrough technology will make heat pumps more effective in cold climates

Reflecting its commitment to decarbonization and the transition to electric heating, Danfoss is excited to introduce an economizer for cold climate heat pumps. A brazed plate heat exchanger coupled with an extra expansion device, the economizer enables scroll compressors with vapor injection, like the Danfoss PSH vapor injection compressor, to operate efficiently at higher operating envelopes.

As the push toward decarbonization and adoption of cleaner heating sources continues, Danfoss is releasing two new compressors for the North American market. The new lineup, which includes the BOCK^® HGX56 CO₂ T 6-cylinder semi-hermetic reciprocating compressor for large-capacity industrial heat pumps and the PSH scroll compressor for reversible rooftop units and hydronic systems in cold climates, offers new and extended compressor ranges to help OEMs accelerate the green transition for comfort and industrial heat pumps.
