Keeping water costs down while working at full capacity

Keeping costs down, while allowing a facility to work at full capacity, can be difficult. But Mitsubishi Heavy Industries Air-Conditioners Australia (MHIAA) has a solution for all manufacturers wanting consistently hot water without hefty bills.

MHIAA’s air to water CO2 heat pump is a WaterMark certified product that provides sanitary hot water outlet temperatures from 60°C to 90°C for commercial applications. The company’s air to water manager, Trent Miller, said the Q-ton heat pump represents the next generation of hot water production. “The Q-ton utilises CO2, a safe, natural and environmentally responsible refrigerant. The combination of CO2s highly efficient, natural accruing properties, enable the Q-ton to be far superior compared to conventional refrigerant heat pumps,” said Miller.

It is engineered to meet a range of demands including the need for medium to large sanitary hot water generation, low electricity consumption and high environmental responsibility. Q-ton can replace old boiler type systems and help customers spend less on energy bills, he said.

With high efficiency rates and low carbon emission, Q-ton recovers heat energy from the air and can perform in extremely cold temperatures, down to -25°C. “Q-ton delivers outstanding performance as a solution based product. Q-ton supplies hot water from 60°C to 90°C at 100 per cent capacity at an outdoor temperature down to -7°C and will continue to produce hot water down to -25°C.”

Globally, Q-ton is already making its mark on commercial spaces. Located in London’s popular Lancaster Gate and Bayswater, Mitsubishi Heavy Industries Air Conditioning Europe connected two Q-ton units to Lancaster Hall Hotel. The system now produces 12,000 litres of water to cater up to 250 people on site. Lancaster Hall Hotel has reduced its running costs by 40 per cent, compared to the boiler system the hotel was previously using. The hotel has saved 45 per cent on carbon emissions.

Mitsubishi Heavy Industries Thermal Systems design team in Japan launched the air source heat pump to allow for maximum efficiency with a minimal carbon footprint. As an ideal system for serving hot water requirements in commercial buildings, Q-ton can be used in varying applications, such as hotels, apartment blocks, restaurants, fitness centres, universities, hospitals, care homes and commercial laundries. It is available across Australia and New Zealand.

A 30kW Q-ton produces in excess of 600 L per hour. The overall L/hr quantity of hot water production varies, as is dependent on the feed water temperature, the outdoor temperature condition and the water outlet setting temperature. By using the modular configuration availability, 16 heat pumps can be connected to provide 480kW capacity and about 100,000 litres of hot water. This capacity can be maintained even in low ambient temperatures and therefore requires no external heating source. Used as a direct replacement for the old boiler type systems, Q-ton can produce hot water during the off-peak tariff electricity times for cost effectiveness whereby this water is then stored in a tank or tanks to control the water supply for the commercial space at the required timings.
