[0015] The technical solution of the present invention is further explained below through specific implementation methods.

[0016] The utility model provides a domestic hot water and water cooling and heating air conditioning system, which is characterized by comprising a domestic water end 1, two water tanks, an air conditioning outdoor unit 2 and an air conditioning indoor unit 3;

[0017] The water tank is divided into water tank 1 4 and water tank 2 5. The water tank 1 4 includes an inner tank and an outer tank. The water tank 1 4 is a double-layer inner tank coil water tank. The domestic water end 1 pipeline is connected to the inner tank of the water tank 1. The water tank 1 heat exchanger is connected to the compressor pipeline in the air conditioner outdoor unit 2.

[0018] The water tank 2 5 is a side coil water tank, and the heat exchanger of the water tank 2 5 is connected to the compressor pipeline; the inner tank pipeline of the water tank 2 5 is connected to the air conditioner indoor unit 3, and between the inner tank of the water tank 2 and the air conditioner indoor unit 3.

[0019] The compressor is connected to a four-way valve 13 and then to a condenser 12. The condenser is connected to a valve seat 8. The valve seat 8 includes a valve portion 1 and a valve portion 2. Two pipelines are connected in parallel in the valve portion 1 and the valve portion 2. A capillary tube 9 and a solenoid valve 10 are provided in one pipeline, and a one-way valve 11 is provided in the other pipeline. The valve portion 1 is connected to a pipeline to the valve portion 2. In the valve portion 2, the capillary tube 9 is connected to the heat exchange coil of the water tank 2. The one-way valve 11 is connected to the heat exchange coil of the water tank 1.

[0020] When the utility model is in use:

[0021] 1. In summer: provide hot water and cold air after operation:

[0022] The refrigerant passes through the compressor and the four-way valve, and the heat generated enters the coil heat exchanger in the water tank 1 to exchange heat with the water in the water tank 1. The water in the inner tank of the water tank 1 is connected to the domestic water end, and the water supply end is connected to the domestic water valve to mix the cold and hot water so that the water temperature is suitable for use;

[0023] After the refrigerant passes through the water tank and undergoes heat exchange, it becomes low-temperature and low-pressure gas and enters Figure 2 The valve seat system generates cold energy after throttling, and the cold energy exchanges heat with the heat exchanger of water tank 2 to cool the water in water tank 2. Then, it is brought to the water-cooled air conditioner in each room through the electric three-way valve and the circulation pump, thereby achieving air conditioning refrigeration.

[0024] When the hot water temperature reaches the set value, the air conditioner outdoor unit exhaust fan is started to discharge the heat. At this time, the cooling function is used.

[0025] 2. Provide hot water and hot air in winter:

[0026] Water tank 2 is deactivated; the heat generated by the refrigerant through the compressor and the four-way valve is exchanged with the water in water tank 1 through the coil heat exchanger in water tank 1, and the water in the inner tank of water tank 1 is connected to the domestic water end;

[0027] The electric three-way valve is reversed, and the hot water in the outer tank of the water tank passes through the electric three-way valve and the circulation pump to the indoor unit of the air conditioner, and the indoor unit of the air conditioner starts heating.

[0028] The cold energy generated during the heat exchange process is discharged to the outdoors through the evaporator.

[0029] 3. Hot water supply only mode:

[0030] After the air conditioner system is turned off, the refrigerant passes through the compressor and the four-way valve, and then exchanges heat with the heat exchanger of the water tank 1, and then returns to the compressor through the evaporator. The water in the inner tank of the water tank 1 is connected to the domestic water end.
