Panasonic Heating & Cooling Solutions, a unit of Japan's Panasonic, has presented a new air-to-water reversible heat pump for commercial, industrial, and multi-dwelling residential applications.
Called ECOi-W Aqua-G Blue, the new product has a variable speed pump that automatically adjusts its speed according to the required capacity and, according to the manufacturer, enables a 70% reduction in annual energy consumption.
The heat pump is available in four versions with a rated power of 50 kW, 60 kW, 70 kW and 80 kW, respectively. “By seamlessly connecting up to 8 units in cascade, the range can efficiently boost capacity up to 640 kW, ensuring adaptability to various project requirements,” the manufacturer said in a statement.
The smallest device measures 1,730 mm x 2,215 mm x 1,032 mm without tank and the largest has a size of 2,030 mm x 2,180 mm x 1,160 mm without tank. The water tank has a capacity ranging from 200 L to 300 L.
The heat pumps feature a cooling capacity of 48.2 kW to 74.1 kW and a heating capacity spanning from 49.2 kW to 83.6 kW. Their coefficient of performance (COP) ranges from 3.2 to 3.4 and their seasonal coefficient of performance (SCOP) is between 3.70 and 3.80.
The new products use propane (R290) as a refrigerant and a highly optimized heat exchanger design, which the company said enables a refrigerant charge reduction.
“Aqua-G Blue can reach up to 70 C leaving water temperature making heat pump systems a sustainable and energy-efficient solution for providing hot water in residential and commercial buildings,” the company said, adding the heat pump has an energy efficiency rating of A++ and a silent mode with a sound power level of 79.9 dB(A). “An optional compressor box is available to provide an additional level of noise reduction.”

I not understanding about your products how I can use the product for steam the water upto 200 digress temperature without any kind of boiling water, if your products can do this type of work then we can accept this for my industry.
Suited for any really very cold weather 12 storey construction… That’s good and huge. I don’t understand the water loop use given the propane coolant but even so the CoP didn’t go under 3? Ah, the water loop’s the indoor one, the outside can tap very cold air to go colder (or warmer and still have that CoP.) Hm.
How hot does water get with these systems and how do they produce a high enough supply temp for heating a house in single to below zero temps outside? Just curious, do the compressors produce hotter refrigerant with the type of refrigerant the system requires? I just don’t understand how this is possible without some kind of backup heat source like electric heat or natural gas heat.
Propane boils at -42C (-44F) at standard pressure. When you let the liquid propane boil is soaks up heat from the outside air. When you compress the gas again it will be hot. How hot depends on the pressure on the liquid side. At 42 bar you can have liquid propane at 100 C.
…Their coefficient of performance (COP) ranges from 3.2 to 3.4 and their seasonal coefficient of performance (SCOP) is between 3.70 and 3.80.
Is it possible for SCOP to be higher than COP??
