Mitsubishi Heavy Industries Thermal Systems (MHI Thermal Systems), a division of Mitsubishi Heavy Industries, has announced the addition of two new heat pump models to the Hydrolution EZY series.
The new models have capacities of 6 kW and 7.1 kW and use propane (R290) as a coolant. In contrast, the existing 10 kW and 14 kW models of the series use difluoromethane (R32).
“The R290 refrigerant used in these models has a very low environmental impact, while maintaining high energy efficiency. This is especially important for the European market, where environmental regulations are becoming increasingly strict,” the manufacturer said in a statement.
The new systems are claimed to maintain a supply temperature of 75C in a wide range of conditions, from outdoor temperatures of -25C to 43C.
“These latest models not only offer high-temperature water heating capabilities, but are also quiet and easy to install, requiring only water pipes and electricity supply to the outdoor unit,” the company added. “When used at maximum capacity, the 6 kW model produces a sound pressure level – a measure of sound intensity – of just 34 dB(A).”
The new products are also equipped with a refrigerant leak detection sensor.
The Hydrolution EZY Series was first launched by MHI Thermal Systems in January. It features a coefficient of performance (COP) ranging from 3.45 to 4.50 and a energy efficiency class (EER) from 2.85 to 3.80.
In March 2023, MHI Thermal Systems unveiled a residential air-to-water heat pump that uses propane (R290) as a refrigerant.
