DC-Inverter Air-Water heat pump Mirai Split
Mirai Split Air-Water DC-Inverter split Heat Pump, composed of an indoor unit with hydronic system and outdoor unit with R32 cooling circuit; thanks to the components, functions, and Twin Rotary compressor, it allows winter heating, summer cooling, and the production of domestic hot water (through a 3-way external valve) in all seasons.
Moreover, the “DC Inverter” technology, in addition to continuous variation of the power to suit demand, also allows optimised management of power consumption, improving the product’s performance so as to ensure compliance with strict energy efficiency criteria.
Refrigerant throttling occurs by means of an electronic expansion valve.
Mirai Split integrates the following main regulation functions: water temperature with proportional and integrative algorithm, dynamic regulation of setpoints by means of the external air probe (temperature regulation), complete management for the integration of auxiliary heating, both by means of a heating element and boiler consent, anti-legionella function, “saving” function for the water circulation pump, defrosting of the external unit exchanger with dynamic de-icing algorithms.
Ease of installation is then combined with the versatility of the machine, which can operate with outside temperatures as low as -20 °C without the use of antifreeze, suitable for different types of systems, radiant (heating/cooling), air terminal units (cassette or fan coils), low temperature radiators, thanks to the wide range of water supply temperature settings, which can reach up to 55 °C.
