INNOVATIVE SOLUTIONS FOR RESIDENTIAL HEAT PUMPS
Heat pumps are a fundamental element in the decarbonisation of the residential heating sector , helping reduce CO 2 emissions . The constant growth in sales of heat pumps in Europe and the United States demonstrates the increasing importance of this technology in the HVAC industry . To address the emerging challenges , CAREL is committed to providing safe and reliable components for managing heat pump refrigerant circuits . A3 ready products guarantee the highest safety , reducing the risk of ignition in the event of contact with flammable refrigerants such as propane ( R-290 ), which are increasingly used in the sector .
E2V-K hermetic expansion valve for high temperatures . The new expansion valve is designed to handle fluid temperatures up to 100 ° C . UL certification and compliance with ATEX regulations ensure safe and reliable operation of heat pumps using natural refrigerants . The numerous sizes available cover a wide range of heating capacities .
3ph inverter with active PFC . The innovative three-phase inverter , already recognised at the recent ICONIC Awards , has
features that make it one of the leaders in the sector . The integrated filtering stage and power factor control allow complete compliance with harmonic emission regulations , ensuring high efficiency and a reduction in energy consumption . Management of variable speed compressors has been optimised compared to traditional drives , consequently extending the operating limits of the envelope . Finally , A3 ready certification means it can be used with natural refrigerants for environmental sustainability .

DANFOSS ’ NEW PSH COMPRESSOR
Danfoss ’ new PSH scroll compressor with vapour injection may be a 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 . Increasing the operating range of heat pumps is essential for achieving decarbonisation .
An R454B optimised dedicated heat pump compressor with higher allowable discharge gas temperature limits , the PSH compressor with vapour injection 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 65 ° C ) 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 vapour 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 can be manifolded and used with a single economiser heat exchanger .
