[0002] Air conditioning, or air conditioner, is composed of four parts: refrigeration (heat) cycle system, air circulation ventilation system, electrical control system and cabinet. The refrigeration cycle system. The refrigeration principle of air conditioning refers to the compressor compressing the gaseous refrigerant into a high-temperature and high-pressure gas, and sending it to the condenser for cooling. After cooling, it becomes a medium-temperature and high-pressure liquid refrigerant and enters the drying bottle for filtration and dehumidification. The medium-temperature liquid refrigerant is throttled and reduced in pressure by the expansion valve (throttling component) to a low-temperature and low-pressure gas-liquid mixture (more liquid). It absorbs heat from the air through the evaporator and vaporizes into a gaseous state, and then returns to the compressor for further compression, and continues to circulate for refrigeration. The condenser is divided into air cooling and water cooling. The waste heat emitted by the refrigerant cannot be recovered, and it is difficult to convert the heat energy into electrical energy for use, resulting in waste of resources and high cost of use.

A through hole is provided in the middle of the outer wall of the power generation box 91 to allow ventilation of the power generation box 91. A third rotating shaft 92 capable of rotating around its own axis is installed at the bottom of the inner cavity of the power generation box 91 through a bearing. A first bevel gear 93 and a second spur gear 94 are installed on the front and rear sides of the outer wall of the third rotating shaft 92, respectively, and the second spur gear 94 is meshed with the first spur gear 88.

The heat dissipation pipe 911 is made of copper and has good heat exchange performance.

An exhaust hole 912 is provided at the bottom of the heat dissipation pipe 911, so that the gas can be discharged from the exhaust hole 912. The heat dissipation pipe 911 is wavy and tilted downward.

[0023] Working principle: Step 1, under the condition that the circulating pump 6 provides power, let the water circulate between the condenser tank 2 and the hot water tank 3. When the air conditioner is refrigerating, the high-temperature and high-pressure refrigerant is transported to the coil 5 through the compressor for heat exchange, so that the water is heated. As the water temperature in the hot water tank 3 rises, the water vapor gradually increases. Once the water vapor pressure exceeds the set value of the pressure reducing valve 10, the water vapor enters the first valve body 731 along the pipeline. Since the first valve core 733 is on the right side, the water vapor enters from the left side of the piston cylinder 82 along the steam pipe 85. The water vapor pressure pushes the steam piston 83 to move right. Once the stop rod 86 touches the lever 812, the lever 812 pushes the moving rod 843 to the left through the insertion rod 845. The left steam pipe 85 is closed, and the right steam pipe 85 is opened. Water vapor enters the piston cylinder 82 from the right side, causing the piston cylinder 82 to move leftward, and the water vapor on the left side of the piston cylinder 82 is squeezed out. Under the obstruction of the first valve core 733, the water vapor enters the heat dissipation pipe 911 along the elbow 842. When the blocking rod 86 pushes the lever 812 to move leftward, the moving rod 843 moves rightward, so that the two steam pipes 85 are switched back and forth, and the piston cylinder 82 moves back and forth left and right. The connecting rod 810 pulls the rotating disk 89 to make a circular motion. Under the transmission of the first spur gear 88, the second spur gear 94 and the third spur gear 96, the generator 95 can rotate to generate electricity, and the electric energy is stored in the lithium battery 11 after rectification; Step 2: When it is necessary to recover the water vapor, the fan blade 99 is rotated under the transmission of the first bevel gear 93 and the second bevel gear 910 to blow air to the heat dissipation pipe 911, and the water vapor passing through the heat dissipation pipe 911 is cooled and liquefied, and water is accumulated in the heat dissipation pipe and flows into the hot water tank 3, so that water recycling is realized; Step three, as the hot water in the hot water tank 3 is gradually lost, the float 738 drops with the drop of the liquid level, the swing rod 737 drives the first valve core 733 to rotate clockwise, the drainage hole 734 is connected with the drainage pipe 72, and the water stored in the water storage tank 71 is supplemented to the hot water tank 3. As the liquid level rises, the swing rod 737 drives the first valve core 733 to rotate counterclockwise, the drainage hole 734 and the drainage pipe 72 are staggered, and the drainage pipe 72 is closed, so that the amount of hot water in the hot water tank 3 is constant, and the stability of power generation is ensured.

[0024] The above are only preferred embodiments of the present invention. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the protection scope of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
