[0021] The present invention will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and thus only show the components related to the present invention.

[0022] Please refer to Figure 1-5 A compressor cooling and heating recovery device comprises an equipment body 1 and a base 5 at the bottom of the equipment body 1, wherein a horizontal support plate 2 is arranged in the equipment body 1, and the support plate 2 divides the equipment body 1 into a lower box body 3 and an upper box body 4, wherein a cold water tank and a hot water tank are arranged in the lower box body 3, and an upper partition 6 is arranged above the upper box body 4, and an air compressor 21 and a heat exchanger 22 are arranged on one side of the upper partition 6, and a heat exchanger (not shown in the figure) is arranged on one side of the air compressor 21, and a heating pipe 23 connected to the heat exchanger is arranged on the other side of the upper partition 6, and the heating pipe 23 extends downward to be connected with the heating pipe 2 24 in the hot water tank, and the heat exchanger 22 is connected with a refrigeration pipe 221 through a pipeline, and the refrigeration pipe 2221 is arranged in the cold water tank.

[0023] When hot water is produced in the hot water tank, the air compressor 21 runs, and the internal energy and temperature are increased by compressing the molecular gaps of the air. At the same time, in the process of converting electrical energy into mechanical energy, part of the electrical energy is also converted into internal energy, which increases the temperature inside the compressor. At this time, the heat generated by the temperature increase is transferred through the heat exchanger, heating pipe 1 23 and heating pipe 2 24, so as to heat the water in the hot water tank, and the heated water can be used for hot water for life or production. When cooling water in the cold water tank, the heat exchanger realizes water cooling through the internal refrigerant circulation. The liquid refrigerant vaporizes in the water heat exchanger and absorbs the heat in the water to lower the water temperature. As the state of the refrigerant changes, the heat is transferred from the water to the air, thereby achieving the purpose of water cooling. The cooled water can be used for base station heat dissipation. The equipment can realize energy recovery, meet the cooling and heating of water, and can save a lot of energy while meeting the needs of life and production. It is highly practical.

[0024] In this embodiment, a cold water tank partition 11 is provided in the cold water tank, and the cold water tank partition 11 divides the cold water tank into a refrigeration water tank 13 and a refrigeration return water tank 14, and the refrigeration water tank 13 is connected to the refrigeration return water tank 14 at the bottom. A hot water tank partition 12 is provided in the hot water tank, and the hot water tank partition 12 divides the hot water tank into a hot water tank 15 and a heating return water tank 16, and the hot water tank 15 is connected to the heating return water tank 16 at the bottom; that is to say, the bottom of the cold water tank partition 11 and the hot water tank partition 12 are not sealed with the bottom of the equipment, ensuring that the cold and hot water tanks are internally connected, which is convenient for the subsequent water circulation.

[0025] Among them, two cold water outlets 132 are provided on the back of the refrigeration water tank 13, a cold water drain port 134 is provided at the front bottom of the refrigeration water tank 13, a float valve 142 and a return water port 143 are provided at the back of the refrigeration return water tank 14, a hot water outlet 152 is provided at the back of the heating water tank 15, a hot water drain port 153 is provided at the front bottom of the heating water tank 15, and a float valve 2 161 and a return water port 2 162 are provided at the back of the heating return water tank 16.

[0026] The cold water outlet 132 is set to facilitate the smooth discharge of internal cold water to dissipate heat for the base station, and the cold water drain port 134 is set to facilitate the complete discharge of water in the cold water tank; the float valve 142 is connected to the external tap water, which can replenish water into the water tank in time, and the return water port 143 is connected to the air-conditioning condensate water, and the tap water and the air-conditioning condensate water are used to replenish water into the cold water tank together, and then the water is discharged for refrigeration after replenishment, and the cycle continues; similarly, the hot water outlet 152 is used to discharge hot water for life and production use, and the temperature is between 40-50°C. The hot water drain port 153 is set to facilitate the complete discharge of water in the hot water tank. In addition, the functions of the float valve 161 and the return water port 162 are the same as those of the above-mentioned float valve 142 and the return water port 143, so they will not be elaborated here.

[0027] In order to ensure the water flow power inside each water tank, a first pump 131 is provided in the refrigeration water tank 13, a second pump 141 is provided in the refrigeration return water tank 14, and a third pump 151 is provided in the hot water tank 15. The output end of the first pump 131 is connected to the two cold water outlets 132 through a tee 133, and the outlet of the second pump 142 is connected to the upper heat exchanger 22. The refrigeration pipe 221 connected to the heat exchanger 22 is provided in the refrigeration water tank 13, the float valve 142 is connected to the external tap water, the return water port 143 is connected to the external air-conditioning cooling water, the output end of the third pump 151 is connected to the hot water outlet 152, the float valve 2 161 is connected to the external tap water, and the return water port 2 162 is connected to the external air-conditioning cooling water.

[0028] Please refer to the water cooling principle Figure 6 When preparing cold water, first inject external tap water or air-conditioning condensate into the refrigeration return water tank 14. After the injection, the second pump 142 starts to input water into the heat exchanger. The heat exchanger realizes water refrigeration through the internal refrigerant circulation. The liquid refrigerant vaporizes in the water heat exchanger and absorbs the heat in the water to reduce the water temperature. With the change of the refrigerant state, the heat is transferred from the water to the air, thereby achieving water refrigeration. The prepared cold water flows out from the refrigeration pipe and enters the refrigeration water tank; since the refrigeration water tank is connected to the refrigeration return water tank, circulating refrigeration can be realized to reduce the water temperature to a greater extent; after the cold water preparation is completed, the first pump 131 is started, and after starting, the prepared cold water is transported to the base station to cool and dissipate the heat. After the cold water is transported, the liquid level in the cold water tank decreases. At this time, external tap water or air-conditioning condensate is replenished through the float valve 142 and the return water port 143.

[0029] Please refer to the water heating principle Figure 7 When preparing hot water, first let external tap water or air-conditioning condensate enter the hot water return tank 16 through the float valve 161 and the return port 162. After injection, the air compressor 21 is operated to increase the internal energy and the temperature through the molecular gap of the compressed air. At the same time, in the process of converting electrical energy into mechanical energy, part of the electrical energy will also be converted into internal energy, which will increase the temperature inside the compressor. At this time, the heat generated by the temperature increase is transferred through the heat exchanger, the heating pipe 1 23 and the heating pipe 2 24, so as to heat the water in the hot water tank. The heated water can be used for hot water for life or production.

[0030] As a preferred solution, the heating pipe 1 23 is arranged in a U-shaped circuitous manner in the vertical direction, and the heating pipe 2 24 is arranged in a spring shape in the hot water tank 15. The heating pipe 1 23 is connected to the heating pipe 2 24 to achieve heat transfer to heat the water.

[0031] In addition, the bottom surface of the upper partition 6 does not contact the support plate 2, which is convenient for the heating pipe 23 to pass through. A heat dissipation fan 61 is provided on the upper partition 6, and the heat dissipation fan 61 is directly opposite to the heating pipe 23. When the water temperature is too high and exceeds a predetermined temperature, the heat dissipation fan 61 starts and blows the heating pipe to lower its temperature, thereby indirectly lowering the water temperature. Heat dissipation grooves are provided around the upper box body 4, and a removable top cover is provided on the top of the upper box body.

[0032] Based on the above embodiment, liquid level sensors are provided in the refrigeration water tank 13 (refrigeration return water tank 14) and the heating water tank 15 (heating return water tank 16); when the liquid level is lower than the set value, the sensor sends a signal and external tap water is automatically replenished; when the liquid level is higher than the set value, the sensor sends a signal to start the corresponding pump to discharge.

[0033] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
