Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, specifically to a waste heat recovery energy-saving combined air conditioning unit. Background Technology

[0002] An air conditioner, or air conditioner, consists of four parts: a refrigeration (heating) cycle system, an air circulation and ventilation system, an electrical control system, and a housing. The refrigeration cycle system works by the compressor compressing gaseous refrigerant into a high-temperature, high-pressure gaseous state, which is then sent to the condenser for cooling. After cooling, it becomes a medium-temperature, high-pressure liquid refrigerant, which enters a dryer for filtration and dehumidification. The medium-temperature liquid refrigerant then passes through an expansion valve (throttling device) to reduce its pressure, resulting in a low-temperature, low-pressure gas-liquid mixture (more liquid). This mixture then absorbs heat from the air and vaporizes, returning to a gaseous state. The vapor then returns to the compressor for further compression, continuing the refrigeration cycle.

[0003] Condensers are divided into air-cooled and water-cooled cooling systems. The waste heat emitted by the refrigerant cannot be recovered, making it difficult to convert the heat energy into electrical energy for use, resulting in resource waste and high operating costs. Therefore, it is necessary to propose a waste heat recovery energy-saving combined air conditioning unit. Summary of the Invention

[0004] The purpose of this invention is to provide a waste heat recovery energy-saving combined air conditioner to solve the problem mentioned in the background art that the waste heat generated by the air conditioner cannot be converted into usable energy and is not energy-efficient.

The circulation pump is installed on the left end of the upper surface of the condenser box. The inlet of the circulation pump is connected to the top of the hot water tank, and the outlet of the circulation pump is connected to the top of the condenser box. The suction of the circulation pump allows circulating water in the hot water tank to be transported into the condenser box, allowing the circulating water to circulate between the condenser box and the hot water tank. The water replenishment mechanism is fixedly connected to the middle of the upper surface of the hot water tank. The energy conversion mechanism is fixedly connected to the upper surface of the bracket. The power generation mechanism is installed on the right side of the front of the energy conversion mechanism.

When the steam piston moves back and forth, the connecting rod converts the linear motion into rotational motion, causing the turntable to rotate; the crossbeam is installed horizontally on the top of the right side wall of the piston cylinder; there are two levers, which are installed on the left and right ends of the front of the crossbeam through pins respectively.

[0009] As a further embodiment of the present invention, a slide rail is provided at the top of the lever.

[0010] As a further embodiment of the present invention, the reversing assembly includes a second valve body, an elbow, a moving rod, a second valve core, and a plug rod.

There are two plug rods, both installed on the front of the moving rod, and the plug rods are inserted into the lever slide.

[0011] As a further embodiment of the present invention, the second valve core is bowl-shaped.

[0012] As a further aspect of the present invention, the objective is to convert mechanical energy into electrical energy, which has the advantage of saving electrical energy. The power generation mechanism includes a power generation box, a third rotating shaft, a first bevel gear, a second spur gear, a generator, a third spur gear, a partition, a fourth rotating shaft, fan blades, a second bevel gear, and a heat dissipation pipe. The power generation box is installed on the right side of the front of the drive box, and through holes are provided in the middle of both the front and rear sides of the power generation box. The third rotating shaft is installed at the bottom of the inner cavity of the power generation box and can rotate around its own axis through bearings. The first bevel gear and the second spur gear are installed on the outer wall of the third rotating shaft from front to back, and the second spur gear is meshed with the first spur gear. The generator is installed on the top of the front of the power generation box. The generator is electrically connected to the lithium battery, and a rectifier and transformer are installed between the generator and the lithium battery. A third spur gear is installed at the input end of the generator and meshes with the second spur gear. A partition is vertically installed at the center of the generator box cavity. A fourth rotating shaft is installed on the outer wall of the partition and can rotate around its own axis through bearings. Fan blades and a second bevel gear are respectively installed at the left and right ends of the fourth rotating shaft, and the second bevel gear meshes with the first bevel gear. A heat dissipation pipe is installed on the left side of the generator box cavity.

[0014] As a further embodiment of the present invention, the heat dissipation pipe is wavy in shape and tilted downwards.

[0015] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows: The present invention circulates water through a circulating pump, and as the water temperature rises, water vapor is gradually generated. A pressure reducing valve releases water vapor at a constant pressure. The water vapor passes through the first valve body and the steam pipe and enters the piston cylinder, pushing the steam piston to move. As the stop rod and the lever collide with each other, the direction of movement of the moving rod can be changed, realizing the switching of the two steam pipes. This causes the piston cylinder to move back and forth, causing the connecting rod to pull the turntable to rotate. Through the transmission between the first spur gear, the second spur gear, and the third spur gear, the generator generates electricity, converting electrical energy into electricity. Stored in a lithium battery, the used water vapor passes through the heat dissipation pipe. Under the transmission of the first and second bevel gears, the fan blades rotate, cooling the water vapor passing through the heat dissipation pipe. The water vapor liquefies to form water, which flows back into the hot water tank, realizing water recycling. The float can rise or fall with the hot water level. When the water level drops, the swing arm drives the first valve core to rotate clockwise, connecting the drainage hole with the drainage pipe. Water stored in the storage tank replenishes the hot water tank. Therefore, waste heat is utilized, and thermal energy is converted into electrical energy for use, saving resources and reducing the cost of air conditioning. Attached Figure Description

One end of the drain pipe 72 is installed at the bottom front of the water storage tank 71, and the other end of the drain pipe 72 is installed with a suspension component 73 embedded in the inner wall of the hot water tank 3.

[0028] The suspension assembly 73 includes a first valve body 731 embedded in the inner wall of the hot water tank 3, with the top front of the first valve body 731 connected to the bottom end of the drain pipe 72. A first valve core 733, capable of rotating around its own axis, is mounted at the center of the inner cavity of the first valve body 731 via a bearing. The first valve core 733 can rotate within the first valve body 731, thus closing the first valve body 731. A drain hole 734 is provided on the outer edge of the front of the first valve core 733. When the drain hole 734 corresponds to the position of the drain pipe 72, a passage is formed, allowing water to flow into the water tank 7. 1.

[0029] Furthermore, the energy conversion mechanism 8 includes a drive box 81 fixedly connected to the upper surface of the bracket 4. A piston cylinder 82 is horizontally mounted on the left inner wall of the drive box 81.

One end of a steam pipe 85 is mounted on each of the left and right ends of the lower surface of the reversing assembly 84. The other end of the steam pipe 85 is mounted on the top outer side of the piston cylinder 82. The reversing assembly 84 allows the two steam pipes 85 to alternately supply steam to the piston cylinder 82, thereby causing the steam pressure to push the piston 83 to move left and right. A stop is mounted on the top right end of the steam piston 83. A second rotating shaft 87, capable of rotating around its own axis, is mounted on the right side of the inner cavity of the drive box 81 via a bearing. A first spur gear 88 and a turntable 89 are respectively mounted on the front and rear ends of the outer wall of the second rotating shaft 87. One end of a connecting rod 810 is connected to the right end of the steam piston 83 via a pin. The other end of the connecting rod 810 is connected to the rear outer edge of the turntable 89 via a pin. As the steam piston 83 moves left and right, the connecting rod 810 pulls the turntable 89 to rotate. A crossbeam 811 is horizontally mounted on the top of the right side wall of the piston cylinder 82. Both the left and right ends of the front of the crossbeam 811 are connected to levers 812 via pins, and a slide is provided on the top of the levers 812.

[0030] The reversing assembly 84 includes a second valve body 841 installed on the top left end of the drive box 81. The bottom of the second valve body 841 is connected to the steam pipe 85, and the top of the second valve body 841 is connected to the pressure reducing valve 10 through a pipe. An elbow 842 is connected to the center of the bottom of the second valve body 841. A movable rod 843 that can slide left and right is inserted into the right side wall of the second valve body 841. A second valve core 844 that is inserted into the inner cavity of the second valve body 841 is installed on the left end of the movable rod 843. The second valve core 844 is cup-shaped and can connect the steam pipe 85 to the elbow 842. Two insert rods 845 that are inserted into the slide of the lever 812 are installed on the right side of the front of the movable rod 843. When the lever 812 is moved by the stop bar 86, the slide provides space for the insert rods 845 to move, and the movable rod 843 moves left and right, so that the second valve core 844 reverses.

[0031] Furthermore, the power generation mechanism 9 includes a power generation box 91 installed on the right side of the front of the drive box 81. A through hole is provided in the middle of the outer wall of the power generation box 91 to allow ventilation. A third rotating shaft 92, capable of rotating around its own axis, is mounted on the bottom of the inner cavity of the power generation box 91 via bearings. A first bevel gear 93 and a second spur gear 94 are respectively mounted on the front and rear sides of the outer wall of the third rotating shaft 92, and the second spur gear 94 meshes with the first spur gear 88. A generator 95, electrically connected to the lithium battery 11, is installed on the top of the front of the power generation box 91. A third spur gear 96, meshing with the second spur gear 94, is installed at the input end of the generator 95. The generator 95 rotates and generates electricity through continuous transmission via the first spur gear 88, the second spur gear 94, and the third spur gear 96. A rectifier and a transformer are also installed between the generator 95 and the lithium battery 11, allowing the generated electrical energy to be rectified and stored in the lithium battery 11. A partition 97 is vertically installed in the middle of the inner cavity of the power generation box 91. The outer wall of the partition 97 is equipped with a fourth rotating shaft 98 that can rotate around its own axis via bearings. The left and right ends of the fourth rotating shaft 98 are respectively equipped with fan blades 99 and second bevel gears 910, and the transmission ratio between the first bevel gear 93 and the second bevel gear 910 is greater than 1, which accelerates the rotation of the fan blades 99 and increases the airflow speed of the fan blades 99. A heat dissipation pipe 911 is installed on the left side of the inner cavity of the generator box 91. The upper and lower ends of the heat dissipation pipe 911 are connected to the elbow 842 and the hot water tank 3 through pipes, respectively. The heat dissipation pipe 911 is made of copper and has good heat exchange performance. The airflow carries away the heat of the heat dissipation pipe 911, which cools the water vapor passing through the heat dissipation pipe 911 and turns it into water. An exhaust hole 912 is opened at the bottom of the heat dissipation pipe 911, which allows the gas to be discharged from the exhaust hole 912. The heat dissipation pipe 911 is wavy and inclined downward. The bottom of the heat dissipation pipe 911 is higher than the first valve body 731, which allows the water accumulated in the heat dissipation pipe 911 to flow into the hot water tank 3, so that the water can be reused.

[0032] Working principle: Step 1, with the power provided by the circulating pump 6, water circulates between the condenser box 2 and the hot water tank 3. During air conditioning cooling, high-temperature and high-pressure refrigerant is delivered to the coil 5 by the compressor for heat exchange, heating the water. As the water temperature rises in the hot water tank 3, 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 pipe. 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 the right. Once the stop lever 86 touches the lever 812, the lever 812 moves the moving lever 843 to the left via the insert lever 845. When the piston cylinder 82 is moved, the left steam pipe 85 is closed and the right steam pipe 85 is opened. Steam enters the piston cylinder 82 from the right side, causing the piston cylinder 82 to move to the left. The steam on the left side of the piston cylinder 82 is squeezed out. Under the obstruction of the second valve core 844, the steam enters the heat dissipation pipe 911 along the bend 842. When the stop lever 86 pushes the lever 812 to move to the left, the moving lever 843 moves to the right, thereby switching the two steam pipes 85 back and forth, causing the piston cylinder 82 to move back and forth. The connecting rod 810 pulls the turntable 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. The electrical energy is rectified and stored in the lithium battery 11.

[0033] Step 2: When water vapor needs to be recovered, the fan blade 99 rotates under the transmission of the first bevel gear 93 and the second bevel gear 910, blowing air onto the heat dissipation pipe 911. The water vapor passing through the heat dissipation pipe 911 is cooled and liquefied, forming water in the heat dissipation pipe and flowing into the hot water tank 3, thus realizing water recycling.

[0034] Step 3: As hot water in hot water tank 3 gradually decreases, float 738 descends with the liquid level. The swing arm 737 drives the first valve core 733 to rotate clockwise, connecting the drainage hole 734 to the drainage pipe 72. Water from storage tank 71 is then added to hot water tank 3. As the liquid level rises, the swing arm 737 drives the first valve core 733 to rotate counterclockwise, displacing the drainage hole 734 from the drainage pipe 72. The drainage pipe 72 is then closed, ensuring a constant amount of hot water in hot water tank 3 and guaranteeing stable power generation.

[0035] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these should also be considered within the scope of protection of the present invention. These will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
