Air-to-Water Heat Pump Combines Energy Efficiency with Sub-Zero Heating Capacities

Johnson Controls-Hitachi has launched the Yutaki M R32 monobloc air-to-water heat pump. This all-in-one solution can deliver heating, cooling and even serve as a domestic water heater with an external tank. The three-ton and four-ton systems are engineered to deliver a consistent, 140 F heating capacity even within sub-zero ambient temperatures and can generate up to four times more thermal energy than electrical energy used.

These capabilities are achieved through a newly designed, vapor injection twin-rotary compressor. The design enables the economizer to control the discharge of temperature prior to it being injected into the compression chamber. The process enhances performance within cold climates, enabling the Yutaki M R32 heat pump to supply 131 F water even within -4 F ambient temperatures.
