(4) When a single heating condition is selected, the electromagnetic valve 16 is closed, the four-way valve A3 is electrified and is in a normally open state, the ground source circulating heat pump 23 operates, the air-conditioning circulating pump 24 operates, and the compressor 1 operates; when the air conditioning heat temperature reaches the set temperature or higher, the ground source circulation heat pump 23 stops operating, and the compressor 1 stops operating. (5) When a single refrigeration working condition is selected, the electromagnetic valve 16 is closed, the four-way valve A3 is not electrified and is in a normally closed state, the ground source circulating heat pump 23 operates, the air-conditioning circulating pump 24 operates, and the compressor 1 operates; when the air-conditioning refrigeration temperature reaches the set temperature or above, the ground source circulating heat pump 23 stops operating, and the compressor 1 stops operating.
4. The air source and ground source integrated multisource full-effect heat pump of claim 1, in the working conditions of independent heating water and preferential heating water, the built-in coil 18 is equivalent to the condensation heat of a condenser in a heat pump system, the condensation heat heats cold water in the pressure-bearing heat-preservation water tank 21 to prepare hot water, and whether the preparation of the hot water is realized by opening the electromagnetic valve 16; in the refrigeration working condition, the outdoor coil pipe 5 or the ground source heat exchanger 6 is equivalent to a condenser of the system, the heat of condensation is released to the environment or a soil source through the fan 22 or the ground source circulating pump, the cold and warm air conditioner heat exchanger 14 is equivalent to an evaporator of the system, and the chilled water is delivered to the tail end of a user through the air conditioner circulating pump 24 after being prepared to realize refrigeration; in the heating condition, the outdoor coil 5 or the ground source heat exchanger 6 is equivalent to an evaporator of the system, heat in the environment or the soil source is transmitted to the indoor coil 5 or the ground source heat exchanger 6 through the fan 22 or the ground source circulating pump for absorption by the refrigerant, the air-conditioning heat exchanger 14 is equivalent to a condenser of the system, and hot water is prepared and then sent to the end of a user through the air-conditioning circulating pump 24 to realize heating.
