In winter, an evaporator of the heat pump is connected with the ground source side, and heat in soil is extracted and heated to supply heat to a room. In summer, a condenser of the heat pump is connected with the ground source side, and heat in a room is transferred to soil through the heat pump. The indoor end system that the ground source heat pump system heats or cools the room is typically a fan coil.
A tail end control system of a traditional heat pump air conditioning system is shown in figure 1, fan coils 11-1 n at the tail end are controlled through respective fan coil temperature controllers 31-3 n, the fan coils and the heat pump host 4 are independent and do not affect each other, and the heat pump host 4 is independently controlled through a host temperature controller 5 and is not affected by the fan coils. When the fan coil is completely closed, the heat pump host 4 is still running, so that energy is not saved; such a control system is not preferable because when the fan coil is turned on, if the heat pump main unit 4 is not turned on, there is no air conditioning effect.
