Mitsubishi Electric
Mitsubishi Electric is launching a new commercial heating system running on CO2
(R744) to deliver
hot water up to 90°C and help businesses increase the efficiency of hot water production whilst significantly reducing their carbon footprint. The 40kW Ecodan QAHV high temperature air source heat pump is specifically designed for commercial sanitary hot water applications in hotels, leisure centres, hospitals, care homes, restaurants, schools and universities. Traditionally these are areas where gas boilers, combined heat and power systems (CHP) or electric water heating have dominated, but as the national grid has become ‘greener’ and decarbonised, the case for modern, electrically-powered air source heat pumps has become stronger and stronger. Capable of flow temperatures from 55°C up to 90°C, the QAHV can produce large delta T’s when it maintains an inlet water temperature lower than 29°C. This also enables it to achieve a Coefficient of Performance (COP) of 3.88. Seasonal efficiencies of the QAHV when producing sanitary hot water at 65°C have also been calculated to be 3 which, when compared to a typical gas boiler, can equate to overall carbon savings of up to 78%. These high levels of efficiency also provide significant savings in running costs and carbon emissions against direct electric heating systems.
The QAHV is designed to deliver high efficiency at high flow temperatures and uses a unique and patented twisted and spiral gas cooler to enhance energy efficiency. Three connected refrigerant pipes are wound around a twisted water pipe which maximizes heat transfer. The continuous spiral grooves in the twisted pipe accelerates the turbulence effect of water and also helps to reduce pressure loss within the heat exchanger which contributes to enhance efficiency. Equipped with Mitsubishi Electric’s latest inverter scroll compressor technology, the QAHV can significantly increase the annual efficiency of a building. R744 or CO2
has a Global Warming Potential (GWP) of 1,
which is the lowest possible, yet the unit can still provide full heating capacity down to -3°C outdoor temperature and operate efficiently and effectively right down to -25°C. The QAHV delivers significant improvements over current high
temperature heat pumps including superb low noise levels of only 56 dB(A). Up to three BREEAM points can be achieved with the use of the QAHV, with 2 points through the use of CO2
as the refrigerant and
another one point from the fact that the circuit is hermetically sealed.

Trane
Trane has expanded its Airfinity portfolio of rooftop air-to-air heat pumps. The new units feature Adaptive Frequency Drive variable speed compressors and are available in capacities from 20 to 65 kW, addressing the needs of small to medium size commercial or industrial buildings.
Thanks to this technology, the units deliver improved part load efficiency, with Seasonal Energy Efficiency Ratio (SEER) up to 5.57 kW/ kW and Seasonal Coefficient of Performance (SCOP) up to 3.38 kW/ kW. All models exceed Ecodesign Directive Tier 2 (2021) requirements. Adapting seamlessly to the building’s demand, the units deliver reduced energy consumption, tighter temperature control and better comfort for the occupants. The rooftops are also adequate for storage areas and warehouses, providing a stable indoor environment. To further increase sustainability of the buildings’ operations, Trane Airfinity rooftops come with additional energy-saving features such as adaptive airflow with variable speed fans, free cooling and heat recovery. Compatibility with Trane Tracer Concierge building management system allows facility managers to manage multiple rooftops remotely using a tablet or a smartphone, adapting the comfort levels to actual building needs. With these new additions to the portfolio, Trane is extending the range down to 20kW as well as up to 300kW, giving building owners more choice and flexibility.
