[0007] Furthermore, the water tank is a double-coil water tank.

[0008] Furthermore, a valve and a circulation pump are provided on the heating end inlet pipeline.

[0009] Furthermore, the compressor is connected to the four-way valve and then to the condenser, and the condenser is connected to a valve seat, and the valve seat includes valve part one and valve part two, and two pipelines are connected in parallel in the valve part one and valve part two, one pipeline is provided with a capillary and a solenoid valve, and the other pipeline is provided with a one-way valve; the valve part one is connected to a pipeline to the valve part two; in the valve part two, the capillary is connected to the indoor unit of the air conditioner; the one-way valve is connected to the water tank heat exchange coil.

[0010] Beneficial effects of the utility model:

[0011] According to calculation, the hot water air conditioning and heating multifunctional system provided by the utility model can produce 4-5 tons of hot water per day under standard working conditions. According to the water consumption of each room of 80-100L, it can provide bathing water for 40-60 rooms, and can also provide cooling for a living room of 100 square meters, so the air conditioning is energy-saving and free hot water. The reason why the hot water air conditioning and heating multifunctional system provided by the utility model is more energy-saving than using solar energy is that: when using air conditioning, the indoor heat is recovered and replaced with hot water, the hot air is not discharged, and there is no air pollution; you can bathe at the same time when heating, and solar energy cannot be used for heating and bathing on rainy days, but this system can be used.

[0012] Therefore, this system can save more energy and recover heat more efficiently than solar energy. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solution of the present invention is further explained below through specific implementation methods. Example

[0017] A hot water air conditioning and heating multifunctional system, characterized in that it includes a heating end 1, a water tank 2, an air conditioning outdoor unit 3, an air conditioning indoor unit 4, and a domestic water end 5; the water tank 2 is a double-coil water tank.

[0018] The water tank 2 is provided with an inner tank and an outer tank; the inner tank is connected to the domestic water end 5; the outer tank of the water tank is connected to the heating end 1; the heat exchange coil in the water tank 2 is connected to the compressor pipeline of the air conditioner outdoor unit 3; the compressor pipeline is also connected to the air conditioner indoor unit 4. The domestic water end 5 is connected to the water supply end, and the water supply end is also connected to the bottom of the water tank inner tank.

[0019] The compressor is connected to the four-way valve 6 and then to the condenser 7. The condenser 7 is connected to a valve seat 8. The valve seat 8 includes a valve part 1 and a valve part 2. Two pipelines are connected in parallel in the valve part 1 and the valve part 2. A capillary tube 9 and a solenoid valve 10 are arranged in one pipeline, and a one-way valve 11 is arranged in the other pipeline. The valve part 1 is connected to a pipeline to the valve part 2. In the valve part 2, the capillary tube 9 is connected to the indoor unit 4 of the air conditioner. The one-way valve 11 is connected to the water tank heat exchange coil.

[0020] The utility model provides a hot water air conditioning and heating multifunctional system with multiple working modes:

[0021] 1. Indoor cooling and hot water making mode:

[0022] Close the heating end, the heat generated by the compression of the refrigerant is used to heat the small inner tank in the water tank through the heat exchange coil. The water in the small inner tank is hot water for bathing. The refrigerant is converted into low-temperature and low-pressure gas after heat exchange in the double-tank coil water tank. Figure 2 The valve seat system generates cold energy after throttling, and the cold energy is discharged into the room through the indoor unit of the air conditioner to cool the room.

[0023] After the hot water is fully heated, the heat is exhausted through the air conditioner's outdoor unit.

[0024] Cooling mode only

[0025] The heat generated by the compressed refrigerant is discharged to the outside through the condenser. Figure 2 The valve seat system generates cold energy after throttling, and the cold energy is discharged into the room through the indoor unit of the air conditioner to cool the room.

[0026] 3. Indoor heating and hot water production:

[0027] The heat generated by the compression of the refrigerant is used to heat the small inner tank in the water tank through the heat exchange coil. The water in the small inner tank is hot water for bathing. At the same time, the heat generated by the coil also heats the water in the large inner tank. Turn on the heating control system, and the radiator is heated through the circulation pump. The refrigerant is converted into low-temperature and low-pressure gas after heat exchange in the double-tank coil water tank. Figure 2 The cold energy generated by the valve seat system after throttling is discharged to the outside through the outdoor unit.

[0028] When only hot water is used, just close the valve on the heating side.
