California ‘Likely’ to Limit GWP for Heat Pump Water Heaters

Electrification of buildings is expected to grow demand for heat pumps, which are currently HFC-based, according to CARB.

The deal is the largest order to date for the young company, launched in the summer of 2020.

CO₂ is the best available technology for air-to-water heat pumps in the 0.5 to 5MW capacity range, according to Fenagy CEO Kim G Christensen.

The air-source Heat2O is said to deliver a COP up to 4.11.

After a forced cancellation in 2021, the event is scheduled to take place in Las Vegas from January 31 to February 2.

Introduced in Europe, MHI’s central control consoles can manage up to 16 Q-ton CO2 units and 128 air conditioners.

The 300kW unit uses cold gas defrost and an expander instead of an ejector.

Vestervig Fjernvarme’s 1.2MW heat pump, to be delivered by Danish CO₂ specialist Fenagy, will replace oil and wood-chip boilers.

Lync’s air- and water-source models are among the few such CO₂ water heaters in North America.

The updated HXSim design and simulation tool can address small-diameter copper tubes in heat exchangers.
