Low ambient temperature EVI air to water (air source) heat pump three in one unit(HVAC central air conditioner 12kW 15kW)

Apply to sanitary hot water,heating,cooling EVI compressor Heating normally in - 25deg C Get free hot water when cooling

Product Features:1.Applied range:sanitary hot water,heating,cooling.2.Enhanced vapor injection compressor,Ambient condition:-25~43 C.3.Five modes:   Hot water;Heating;Cooling;Heating + Hot water;Cooling + Hot water.4.In summer,On the cooling+hot water model,unit will be cooling,or hot water,or two at the same time automatically.5.In winter,On the heating+hot water model,unit will be heating,or hot water,or two at the same time automatically.6.Heat recovery technology,get free sanitary hot water when cooling.7.Three heat exchangers. The sanitary hot water and the heating (cooling) water is completely separated.8.Eco-friendly refrigerant: R407C .9.Two speed fan motor:further improve unit operation(hot water model)under high ambient temperature.10.Expansion valve regulates the flow of refrigerant precisely.11.Galvanized plate shell, powder coating.12.LCD display wire controller.13.Can set the operating time freely. 14.Unit runs or stop automatically according to water temperature.15.Compatibility of indoor signal control(10~12V).16.Can control the auxiliary heating (e.g. electric heating).17.With hot water return control, to keep the water warm in supplying pipe.18.Water flow protection control.19.Automatic prevent freezing in the winter.20.Automatic defrosting.21.Failure diagnosing function.
