LG presents residential air-to-water heat pump

The system uses difluoromethane (R32) as the refrigerant and has reportedly a seasonal coefficient of performance of up to 4.69.

South Korean electronics manufacturer LG has launched its G R32 Air-to-Water Heat Pump Monobloc residential heat pump at the Canadian Mechanical and Plumbing Expo (CMPX), taking place this week in Toronto, Canada.

“The LG R32 Air-to-Water Heat Pump Monobloc system provides ease of installation by seamlessly integrating hydronic components, using water pipes to eliminate the need for refrigerant piping,” the company said in a statement. “Powered by LG’s advanced heat pump technology, the R32 Air-to-Water Heat Pump Monobloc efficiently produces hot water for various applications, including space heating and domestic hot water.”

The system uses difluoromethane (R32) as the refrigerant, which has a global warming potential (GWP) of 675. It has a size of 1,239 mm x 1,380 mm x 330 mm and has a weight of 115.5 kg.

LG is offering the heat pump in four versions with nominal capacities of 5 kW, 7 kW, 9 kW, 12 kW, 14 kW, and 16 kW. Its seasonal coefficient of performance (SCOP) can reportedly reach up to 4.68.

The heat pump can operate within versatile leaving water temperature ranges, covering cooling up to 27 C and heating up to 65 C. The manufacturer also claims the new system can maintain 100% of its heating capacity at -15 C outdoor temperature, with leaving water temperature reaching up to 55 C.

“Incorporated noise reduction technology, such as an encapsulated compressor and vibration decoupling, operates at audio levels as low as 49dB at a 1m distance,” the manufacturer added. “The product sets a new standard in heating, ventilation, and air conditioning (HVAC) innovation with reduced defrost cycles, extended operation time and intervals.”

This new LG R32 Air-to-Water Heat Pump Monobloc sounds like a significant advancement in HVAC technology. The use of R32 refrigerant with a lower global warming potential is a great step toward sustainability. I’m particularly impressed by its ability to maintain 100% heating capacity even at -15°C, which makes it suitable for colder climates. The noise reduction features and high SCOP rating further highlight its efficiency and user-friendly design. It’s exciting to see innovation that combines energy efficiency with practical usability. Are there any plans to expand its availability beyond Canada in the near future?

I thought years ago on car a/c R32 use was stopped and 134a used instead, as it was better for the environment.

No, that was R12.
