The control method is the preferred control method under the first working condition of the invention, namely the preferred control method under the condition of sufficient solar radiation in the daytime, and the function of heating water by solar energy alone (enough without starting the heat pump) can be realized. Firstly, the temperature T set of the solar heat collector is detected, if the T set is more than T heat, the solar heat collector is adopted to produce hot water independently, at the moment, a water way on the hot water circulating side of the first water pump 9 is started, and the second water pump 17 is closed.
Preferably, the first and second electrodes are formed of a metal,

The solar water heater is an optimal control mode under the second working condition, namely, solar energy and air energy can be used for heating water when solar radiation is insufficient in the daytime (the solar water heater is insufficient only, sunlight is insufficient at the time, the temperature of the heat collector is lower than that of the hot water tank, the hot water cannot be heated independently, but is higher than the ambient temperature, and the heat collector can be used as an evaporator). If T set is detected to be T ring < T set and T heat is less than or equal to T set, the solar heat collector and the air-conditioning heat pump unit are linked, the solar heat collector serves as an evaporator at the moment, the evaporation temperature of the whole system is increased, the fan runs through a low windshield, and the unit operation energy efficiency is further improved (the temperature of the heat collector is higher than the ambient temperature, the evaporation temperature of the refrigerant in the heat collector is higher than that of the refrigerant when the refrigerant independently (does not move the heat collector) moves the evaporator, and therefore the evaporation temperature of the whole system is increased). The control is as follows: the hot water electromagnetic valve is opened, the cold water electromagnetic valve is closed, the second water pump 17 is opened, the first water pump 9 is closed, the first control valve 5 (preferably the first electromagnetic valve) is opened, the second control valve 6 (preferably the second electromagnetic valve) is closed, the unit starts to operate in a hot water heating mode, and the fan operates in a low-windshield mode.
Preferably, the first and second electrodes are formed of a metal,
when a fan 10 for radiating heat of the outdoor heat exchanger 11 is further included, the fan 10 is turned on and operated to a low windshield. Because the evaporation temperature of the system is high, the fan does not need to operate a high windshield to improve the evaporation temperature, so that the fan operates at a low level, the power of the whole machine is low, and the energy efficiency of the unit is improved. The larger the general windshield is, the higher the fan power is, the larger the air quantity is, and the better the heat exchange effect of air and fins is.
Preferably, the first and second electrodes are formed of a metal,

Preferably, the first and second electrodes are formed of a metal,
when a fan 10 for radiating heat of the outdoor heat exchanger 11 is further included, the fan 10 is turned on and operated to a medium wind range. If the T set is detected to be T ring-2 < T set is less than or equal to T ring, the linkage mode of the solar heat collector and the air-conditioning heat pump unit is also adopted, but the wind shield is used during the operation of the fan. When the T set of the heat collector is T ring-2 < T set < T ring, although the temperature of the heat collector is less than or equal to the ambient temperature, but higher than the evaporation temperature of the system (the evaporation temperature is generally 6 ℃ lower than the ambient temperature), part of heat in the heat collector can absorb heat for the refrigerating system. At the moment, the heat of the heat collector is not sufficient, the T set is more than T-2 and less than or equal to T ring, but the evaporation temperature of the system can be slightly increased, and the wind gear during the operation of the fan can meet the evaporation requirement of the system.

The control method is the preferred control mode under the fourth working condition of the invention, namely when the solar radiation is more insufficient in the daytime, the temperature of the solar heat collector can not provide the refrigerant for evaporation and heat absorption, and only the heat pump can be operated independently to complete the preparation of the hot water.
Preferably, the first and second electrodes are formed of a metal,
when a fan 10 for radiating heat of the outdoor heat exchanger 11 is further included, the fan 10 is turned on and operated to a high damper.

The refrigerant firstly enters the heat collector for heat dissipation and then enters the condenser for heat dissipation, so that the condensing pressure of the system is reduced, the rotating speed of the fan can be reduced, the power consumption is reduced, and the condensing and heat dissipation requirements of the air conditioner can be met; when the high-pressure temperature is high, the high-pressure side heat exchange effect is poor, the rotating speed of the fan needs to be increased at the moment, the heat dissipation of the condenser is promoted, and if the high-pressure temperature is low, a low windshield can be operated, and the power consumption of the fan is reduced.
When refrigeration water is needed at night (in summer, refrigeration water is used for refrigeration of users at night, and the users can blow cold air by connecting the air disc), the functions of radiation refrigeration and air conditioning refrigeration can be realized.
