As shown in Figure 1, the present invention provides a water-cooled waste heat recovery solar mobile heat pump air conditioner, including an air conditioner housing 20, a solar collector 19, a top water tank 16, a bottom water tank 17, a heat exchange coil 9, and a spiral heat exchange coil 10. Heat exchanger 4, compressor 1, gas-liquid separator 2, four-way valve 3, filter device 5 (8), throttling device 6, three-way valve 7, insulation box 18, float valve 12, axial fan 11. Temperature sensing adjustment device 13, universal wheel 21 and chassis 22; the universal wheel 21 is installed under the chassis 22; one end of the throttling device 6 communicates with the heat exchanger, and the other end communicates with the three-way valve 7 One end communicates with the two ends of the three-way valve 7 , one end communicates with the heat exchange coil 9 , and the other end communicates with the solar collector 19 and the spiral heat exchange coil 10 in series. During refrigeration, the high-temperature and high-pressure gaseous refrigerant passes through the four-way valve 3, exchanges heat with water through the heat exchange coil 9 in the insulated box 18, transforms into a high-pressure and low-temperature liquid refrigerant, and then enters the heat exchanger through the throttling device 6 4. Absorb the excess heat in the room and turn it into a low-temperature and low-pressure gaseous refrigerant. The operation of the axial fan 11 forces the indoor air to continuously enter from the air inlet 15, and release the excess heat to the heat exchanger 4. The temperature drops and becomes cold air. It is sent out through the air outlet 14 to achieve the effect of cooling the air in the room; when heating, the refrigerant is a high-temperature and high-pressure gas passing through the heat exchanger 4, and after releasing heat, it becomes a high-pressure and low-temperature liquid refrigerant, which is throttled and reduced by the throttling device 6. After being compressed, heat is absorbed from the solar collector 19 and the spiral coil 10 through the three-way valve 7, and then enters the compressor 1, where it becomes a high-temperature and high-pressure gaseous refrigerant again, and the heat is continuously passed through the heat exchanger 4 to Indoor heating. The axial flow fan 11 operates to make indoor air enter from the air inlet 15, absorb heat through the heat exchanger 4 and heat up to become hot air, and send it out through the air outlet 14, thereby achieving a heating effect.

In this embodiment, the heat dissipation coil 9 is placed in the heat preservation box 18, and the heat preservation box 18 is located in the middle of the top water tank 16 and the bottom water tank 17. , Bottom water tank 17 is connected in series. When cooling, first add an appropriate amount of water to the top water tank 16, and the water flows into the heat preservation box to soak the heat dissipation coil 9 in the water. When the water in the heat preservation box reaches a certain capacity, the float valve 12 is closed, and the heat dissipation coil 9 is replaced with water. When the heat makes the water temperature rise to a certain temperature, the temperature-sensitive adjusting device 13 opens the valve when setting the matching temperature, and discharges the hot water in the incubator to flow to the bottom water tank 17.

The bottom water tank 17 is provided with an independent alarm device. Once the bottom water tank 17 is full of water, the alarm device will cut off the power supply of the compressor 1 to remind the user to remove the water in the bottom water tank 17 for daily life such as washing hands or clothes. use water.

Since the compressor 1 releases a large amount of heat through the outer shell during heating, the four-way valve 3 and the three-way valve 7 are energized at the same time, and the high-temperature and high-pressure refrigerant is discharged from the compressor 1. It flows into the heat exchanger 4 through the four-way valve 3 for heat exchange, and then flows through the throttling device 6 to transform into a low-temperature and low-pressure liquid refrigerant, and flows into the solar collector 19 and the spiral heat exchange coil 10 through the three-way valve 7 to absorb heat Then it turns into a low-temperature and low-pressure gaseous refrigerant, enters the compressor 1, and turns into a high-temperature and high-pressure gaseous refrigerant to realize a heating cycle system and improve system efficiency.
