New Generation Sanitary Hot Water Solution
Mitsubishi Heavy Industries Air-Conditioners Australia (MHIAA) has recently implemented the next stage of the global launch of Q-ton by introducing this air to water CO₂ heat pump to the Australian and New Zealand market.
The recently WaterMark[1] certified product provides sanitary hot water outlet temperatures from 60°C to 90°C for commercial applications. Q-ton is the next generation hot water solution.
“Q-ton 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.” says Trent Miller, Air to Water (A2W) Manager, MHIAA.
Mitsubishi Heavy Industries Thermal Systems design team in Japan launched this innovative and unique 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 utilised in varying applications, such as; hotels, apartment blocks, restaurants, fitness centres, universities, hospitals, care homes and commercial laundries.
With high efficiency rates and low carbon emission, Q-ton recovers heat energy from the air and can perform in extremely cold temperatures right down to -25°C[2].
“Q-ton delivers outstanding performance as a solution based product. Q-ton supplies hot water from 60°C to 90°C at 100% capacity at an outdoor temperature down to -7°C and will continue to produce hot water down to -25°C”- Trent Miller
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 represents the efficient solution to the old boiler type systems found in most commercial settings.
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 utilising the modular configuration availability, 16 x heat pumps can be connected to provide 480kW capacity and approximately 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 for example, 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.
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 (MHIAE) recently connected two Q-ton units to Lancaster Hall Hotel. This system now produces 12,000 litres of water to cater up to 250 people on site. Lancaster Hall Hotel has now reduced their running costs by 40% compared to their existing boiler system and have seen a 45% saving on carbon emissions*[3].
With the launch of Q-ton now being extended to include both Australia and New Zealand, Mitsubishi Heavy Industries is now offering the market a hot water solution to meet the increasing demands of commercial spaces. The Q-ton solution is here.
