[0001] The present invention relates to an improved invention in the field of air conditioning technology, and in particular to an improved invention of an air conditioning combination system. Background Art

[0002] When the air conditioner is running in cooling mode, the indoor hot air is cooled by cold exchange with the air conditioner, effectively meeting people's requirements for temperature comfort. However, the high-temperature and high-pressure refrigerant medium generated by compression by the compressor directly discharges the heat to the outside, and cannot be reasonably recycled and utilized, resulting in energy loss. In addition, because the generation of waste heat is affected by the season and the air conditioner working mode, the recycling and utilization is intermittent and cannot meet the continuous use needs. Summary of the invention

[0005] The waste heat recovery heat exchange component is a coil-type heat exchange tube arranged in the lower inner tank, or a coil-type heat exchange tube arranged on the outer periphery of the lower inner tank, or a belt-type microchannel heat exchanger arranged on the outer periphery of the lower inner tank.

[0006] The air energy heat exchange component is a coil-type heat exchange tube arranged in the upper inner tank, or a coil-type heat exchange tube arranged on the outer periphery of the upper inner tank, or a belt-type microchannel heat exchanger arranged on the outer periphery of the upper inner tank.

[0007] The upper inner tank is also provided with an electric heating tube, a temperature probe and a temperature control system. The temperature control system is connected to the temperature probe signal, and the electric heating tube is controlled to be on and off by the temperature control system.

When the air conditioner is heating or not working, the air energy is used to heat the upper inner tank, and the upper inner tank supplies hot water to the outside. When the weather is extremely cold and the heating temperature is too low, the electric heating tube is involved in the work to assist in heating to reach the required temperature.

[0018] The accompanying drawings show the structure of the present invention, and the relevant details are further described below in conjunction with the accompanying drawings. Figure 1 and 2In this embodiment, the air conditioning combined system includes an air conditioning indoor unit 1, an air conditioning outdoor unit 2, a refrigerant pipe 3 and a capillary tube 4. The air conditioning indoor unit 1 includes an evaporator, the air conditioning outdoor unit 2 includes a compressor and a condenser, the refrigerant pipe 3 is connected in series with the evaporator, the compressor and the condenser in sequence, the capillary tube 4 is connected in series with the condenser and the evaporator, and the refrigerant pipe 3 between the compressor and the condenser is connected in series with an insulation water tank 5, and the insulation water tank 5 is provided with an upper inner tank 6 and a lower inner tank 7 distributed up and down, and the lower end of the upper inner tank 6 is connected to the lower inner tank The upper end of the lower inner tank 7 is connected through a circulation pipe 8, and the circulation pipe is located in the insulated water tank. The lower inner tank 7 is equipped with a waste heat recovery heat exchange component 9 for heat exchange with the lower inner tank, and the waste heat recovery heat exchange component 9 is connected in series with the refrigerant pipe 3. The upper inner tank 6 is equipped with an air energy heat exchange component 10 for heat exchange with the upper inner tank, and the air energy heat exchange component 10 is connected to an air energy heating device 11. The insulated water tank 5 is provided with a cold water inlet 12 and a hot water outlet 13 connected to the upper inner tank 6. The cold water inlet 12 is connected to the water inlet pipe, and the hot water outlet 13 is connected to the shower head. The air energy heating device 11 is a prior art and will not be described in detail here. The circulation pipe is located in the insulated water tank, which can prevent the circulation pipe from freezing in cold weather. When the air conditioner is used for heating in cold weather, the low-temperature refrigerant medium passing through the waste heat recovery heat exchange component will transfer the low temperature to the lower inner tank, causing the water in the lower inner tank to freeze and expand, and some of the water can be squeezed through the circulation pipe into the upper inner tank to prevent the lower inner tank from expanding and rupturing.

[0019] The working principle of the present invention is that cold water enters the upper inner tank 6 through the cold water inlet 12, and enters the lower inner tank 7 through the circulation pipe 8. When cooling in summer, the compressor compresses the refrigerant medium into a high temperature and high pressure state, enters the thermal insulation water tank 5 through the refrigerant pipe 3, and heats the water in the lower inner tank 7 through the waste heat recovery heat exchange component 9 of the lower inner tank 7. The heated water in the lower inner tank 7 uses the lift of hot water to enter the upper inner tank 6 through the circulation pipe 8, and hot water is supplied to the outside through the hot water outlet 13. The refrigerant medium after heat exchange continues to dissipate heat through the condenser, and the cooled high-pressure refrigerant medium flows back to the evaporator through the capillary 4 to absorb heat, thereby cooling the room. When heating in winter or not working, the heat generated by the air energy heating device 11 directly heats the upper inner tank 6 through the air energy heat exchange component 10, and hot water is supplied to the outside through the hot water outlet 13.

[0020] As a further improved specific implementation method, the waste heat recovery heat exchange component 9 transfers the air-conditioning waste heat carried by the refrigerant to the lower inner tank. It can be a coil-type heat exchange tube arranged in the lower inner tank, or a coil-type heat exchange tube arranged on the outer periphery of the lower inner tank, or a belt-type microchannel heat exchanger arranged on the outer periphery of the lower inner tank.

[0021] As a further improved specific implementation method, the air energy heat exchange component 10 transfers the air energy carried by the refrigerant to the upper inner tank, and can be a coil-type heat exchange tube arranged in the upper inner tank, or a coil-type heat exchange tube arranged on the outer periphery of the upper inner tank, or a belt-type microchannel heat exchanger arranged on the outer periphery of the upper inner tank.

[0022] As a further improved specific implementation, the upper inner tank 6 is further provided with an electric heating tube 14, a temperature probe and a temperature control system, the temperature probe includes a high temperature probe tube 15 and a low temperature probe tube 16, the temperature control system is connected to the temperature probe signal, and the electric heating tube 14 is controlled on and off by the temperature control system. When the temperature of the hot water generated by the upper inner tank 6 does not meet the requirements, the temperature control system receives the temperature signal of the temperature probe to control the electric heating tube 14 to perform auxiliary heating.

[0023] As a further improved specific implementation method, the air energy heating device 11 is arranged in the air-conditioning outdoor unit 2 to perform structural integration, thereby reducing space occupancy and reducing costs, and facilitating installation.

[0024] As a further improved specific implementation method, the air-conditioning outdoor unit 2 can be detachably installed on the upper end of the thermal insulation water tank 5, so that the structural layout is more reasonable and the space occupation is reduced. At the same time, it can be detachably connected for easy transportation.

[0025] As a further improved specific implementation, the upper end of the circulation pipe 8 is connected to the center of the lower end of the upper inner tank 6, and the lower end of the circulation pipe is connected to the center of the upper end of the lower inner tank 7. Preferably, a hot water conduit and a cold water conduit are provided in the circulation pipe 8, and the upper end of the hot water conduit is higher than the upper end of the cold water conduit, and the lower end of the hot water conduit is higher than the lower end of the cold water conduit, so as to improve the circulation efficiency of hot water rising from the lower inner tank 7 into the upper inner tank 6 and cold water descending from the upper inner tank 6 into the lower inner tank 7.

[0026] As a further improved specific implementation method, an air filter 17 is provided at the air inlet of the air-conditioning indoor unit 1 to filter and purify the indoor air to achieve multi-functions.

[0027] As a further improved specific implementation, a magnesium rod installation opening 18 is further provided on the upper inner shell for installing a magnesium rod.
