Cooling in Summer; Heating in Winter; supplying sanitary hot water all the year.
Energy-efficient: The ratio output against input is coefficient of performance (COP). Normally it can be more than 4.
Environmental protection :There is no waste water, waste residue, used heat, the waste gas discharged. It will not produce any pollution to the atmosphere and environment.
Modular controlling function: As per the actual requirements, one or more units can be added to combine a heat water supply system, which are controlled by modular. `
Automatic energy balance: According to ambiguous controlling principle, the unit checks the load dynamically. When the unit reaches the setting temperature, the unit keeps the load in balance.
