Sanyo launches R410A heat-pump range
Sanyo has introduced a range of R410A air-to-water heat pumps to complement its successful Eco CO2 series as part of the company’s Heating Solutions range. The new split system is available with capacities from 5 to 24 kW and provides hot water at up to 50°C for underfloor heating and radiators. It can also provide hot and chilled water for heating and cooling via fan-coil units.
The use of DC inverter-driven rotary compressors enables heating COPs of around 4 to be achieved. Starting currents are also low, at around 2 A.
The outdoor unit can be up to 30 m from the indoor unit. The compact indoor unit contains a high-efficiency plate heat exchanger, back-up electric heaters, water pump and central control panel. The indoor and outdoor units are connected by two small refrigerant pipes, which must be installed by a suitably qualified installer
The control system uses a combination of room and water temperature sensors to optimise energy performance and comfort.
