The Q-ton Story:
The high efficiency Q-ton is an air-to-water heat pump using CO2 gas as a refrigerant, which can be used in a variety of applications for the supply of sanitary hot water. Q-ton has been featured as the world’s first two-stage compressor (combining rotary and scroll technology). It maintains high efficiency and significantly improves performance at cold outside air temperatures.
MHI’s design team launched this innovative unique air source heat pump to allow maximum efficiency, with minimal carbon footprint all controlled from a comprehensive touch screen panel. Currently with the increasing pressure of the use of low GWP (Global Warming Potential) refrigerant, we believe CO2 heat pump is the way forward to comply with future regulations as well as market trends.
Systems can be set up to meet specific requirements, from one 30kW Q-ton unit providing 6,000 litres of hot water a day, to 16 heat pump units in a modular configuration of 480kW, connected to substantial hot water storage tanks. A touch screen controller makes the system simple to operate, while the user-friendly graphic display enables you to easily monitor hot water production and availability.
How it works:
Q-ton is a heat pump with natural R744 (CO2) refrigerant to be used for high temperature domestic hot water production in residential, commercial, tourist and industrial applications. Q-ton can heat and produce hot water up to 90°C in the presence of an outdoor temperature of -25°C. The new dual stage compressor manufactured and patented by Mitsubishi Heavy Industries is used to achieve this result.
The use of R744 refrigerant gas (CO2) guarantees a very low environmental impact. It in fact has a global warming index (GWP) of 1 , and a potential for ozone layer destruction (ODP) of 0.
Energy savings: up to 78% less than a combustion boiler
The Benefits:
- It generates hot water at up to 90°C without the requirement for an electric immersion heater.
- Its Monobloc unit with CO2 refrigerant has Zero Ozone Depletion Potential (Zero ODP) and a Global Warming Potential (GWP) of 1.0, which is the lowest achievable.
- With an industry leading CoP (Coefficient of Performance) of 4.3, it is the ideal system for serving hot water requirements in commercial buildings like hotels, care homes and leisure centres.
- Sanitary hot water (65-90°C) even in cold temperatures
- Natural refrigerant (CO²)
- No output capacity reduction from -7°C
- Up to 6 times more efficient than a gas boiler
- Up to 50% less carbon emissions than a gas boiler
- 5,000 to 100,000 L/day configurations
- Easy-to-use touchscreen controller
- Very low operational noise
Using a Q-ton heat pump system substantially reduces running costs and carbon emissions by 40 to 75%. It is suitable for installation in new and existing buildings, and does not require a heating back up.
Did you know the Q-ton is approved for Enhance Capital Allowance (ECA)?
The ECA scheme is open to all UK businesses that pay Corporation Tax or Income Tax, providing they have used equipment on the energy technology list.
Heat Pump Systems
There are three types of heat pumps: air-to-air, water source, and geothermal. They collect heat from the air, water, or ground outside your home and concentrate it for use inside.
