Mitsubishi unveils propane heat pump for residential applications


Mitsubishi Electrical presents an air-source warmth pump that makes use of propane (R290) as a refrigerant. It will possibly produce between 5 kW and eight.5 kW of warmth and home scorching water as much as a temperature of as much as 75 C.

Japan-based electronics producer Mitsubishi Electrical has unveiled an air-source warmth pump primarily designed for changing warmth turbines in current buildings. It makes use of propane (R290) as a refrigerant, which has a worldwide warming potential (GWP) of three.

“Our specialist commerce companions in Germany repeatedly approached us with requests for such an answer,” mentioned Dror Peled, deputy division supervisor of Mitsubishi Electrical in an announcement. “With our Ecodan fashions with R290 refrigerant as a monoblock variant, we now provide our prospects entry into the regeneration market with comparatively excessive circulation temperatures primarily based on pure refrigerants .”

The R290 Ecodan monoblock can be utilized with heating capacities of 5 kW, 6 kW, and eight kW. There are additionally plans to develop the mannequin sequence with increased warmth outputs of as much as 14 kW within the coming years, Mitsubishi mentioned in an announcement.

The warmth pump can supposedly produce scorching water as much as 75 C with exterior air right down to -15 C, or as much as 65 C for air temperatures right down to -25 C. “In comparison with standard units , it represents a big growth of areas. of utility,” claims Mitsubishi, including that for optimum energy-efficient operation, the really helpful circulation temperature is 55 C.

The brand new system is designed as a monoblock system with the choice of including a hydro module as an inside unit or a buffer tank for decent water storage with a capability of 200 or 300 liters.

Mitsubishi sells the warmth pump solely as a monoblock attributable to particular security necessities for warmth pumps utilizing propane as refrigerant for residential functions.
