The Japanese company Panasonic has developed an aerothermal heat pump that uses propane (R290) as a refrigerant.
Panasonic has introduced the Aquarea K and L series of heat pumps, which use R32 and propane (R290) as refrigerants, respectively.
The propane L-series is “ideal for retrofit applications when renovating a home with existing radiators,” Panasonic said in a statement. He noted that the K series is designed for new construction applications. Propane heat pumps have a heating capacity of 5 kW to 8 kW, measure 996mm x 980mm x 430mm and weigh 98kg.
They have a coefficient of performance (COP) of up to 5, according to the companys technical data sheet. The air source temperature can range from -25ºC to 35ºC for heating and 10ºC to 43ºC for cooling. Heat pumps can produce hot water up to 75°C.
Its seasonal coefficient of performance (SCOP) for heating water at 35ºC in “medium climate” varies between 5.06 and 4.84, while the SCOP for applications at 35ºC in “cold climates” varies between 4.25 and 4.31. For 55ºC applications, the SCOP is up to 3.67 and 3.33, respectively. The heat pumps are also photovoltaic “smart grid ready”, according to Panasonic.
“The new generations Aquarea K and L benefit from a reduced noise level, up to 8dB(A) less than the previous models”, said the manufacturer. "This advantage makes installation more flexible by offering more placement possibilities."
The two models share the same design, with an outdoor unit in anthracite gray and a white indoor unit. |
