Mitsubishi launches CO2 heat pump

Mitsubishi has launched an air-to-water CO2 heat pump aimed at commercial markets. The pump uses a compressor to heat water to 90°C and works even when outdoor temperatures fall to -25°C. The Q-Ton is able to reach 90°C without additional energy from a conventional boiler, reducing running costs and environmental impact.

The Q-Ton has a high efficiency two-stage combined scroll-rotary compressor and uses natural R744 (CO2) refrigerant, which has zero Ozone Depletion Potential.

The model cuts running costs by 58% and lowers carbon emissions by 44% compared to a gas boiler. It consumes 76% less energy than an electric water heater and boats the lowest possible Global Warming Potential, scoring one, as R744 is a naturally occurring gas.

It has a high Coefficient of Performance of up to 4.3 when the outdoor temperature is above 7°C and almost 2.0 when -25°C. A single Q-Ton 30 kW unit weighs in at 365kg – the lightest in the industry.

The Q-Ton features a touch screen operations panel and a user-friendly graphic display indicating production and availability of hot water.  A precise controller senses need, preventing heating water constantly.


Mitsubishi Heavy Industries (MHI) sales manager Des Franklin said: "MHI is accurately assessing future needs with the launch of the Q-Ton. The Q-Ton is revolutionary as it allows businesses to supply hot water far more efficiently, which is cost-effective and eco-friendly."

MHI estimates that the capital investment will be less than an equivalent output gas boiler and on-going costs will decrease year on year.
