For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. The embodiments of the present invention will be described below according to the overall structure of the present invention.

[0020] Refer to Figures 1 to 4 , in the embodiment of the present invention, a water-cooled scroll industrial chiller includes: a connection end 1, a solenoid valve 2 is fixedly connected to the side of the connection end 1, a filter 3 is fixedly connected to the side of the solenoid valve 2, a compressor 4 is fixedly connected to the side of the filter 3, a compressor base 5 is fixedly arranged below the compressor 4, a gas transmission pipeline 6 is fixedly connected to the other side of the compressor 4, and a condenser 7 is fixedly connected to the side of the gas transmission pipeline 6.

[0021] Adopting the above solution: The settings of the solenoid valve 2 and the filter 3 ensure the purity and flow control of the refrigerant gas entering the compressor 4, effectively preventing impurities from entering and protecting the compressor from damage. The stable installation of the compressor base 5 provides good support for the compressor, while the gas transmission pipeline 6 efficiently transports the compressed high-temperature and high-pressure gas to the condenser 7, preparing for the next stage of the refrigeration cycle.

[0022] Above the condenser 7, a water pump 8 is fixedly connected. Above the water pump 8, a return water pipeline 9 is fixedly connected. On the other side of the return water pipeline 9, a water cooling tower 10 is fixedly connected. Below the water cooling tower 10, a water cooling tower base 11 is fixedly arranged. On the side of the water cooling tower base 11, a water pump 12 is fixedly arranged. On the side of the water pump 12, a water transmission pipeline 13 is fixedly connected. On the other side of the water transmission pipeline 13, one side of the condenser 7 is fixedly connected. On the other side of the condenser 7, an expansion valve 14 is fixedly connected. On the side of the expansion valve 14, an evaporator 15 is fixedly connected. On the side of the evaporator 15, a cooling chamber 16 is fixedly arranged

[0023] Adopting the above solution: The cooperation of the water pump 8 and the return water pipeline 9 ensures that the high-temperature cooling water can smoothly flow back to the water cooling tower 10 for cooling. Through its cooling function, the water cooling tower 10 dissipates heat into the atmosphere, and then the cooled water is re-transported to the condenser 7 by the water pump 12 and the water transmission pipeline 13 to complete the heat exchange process.

[0024] On the other side of the cooling chamber 16, an air extraction pump 17 is fixedly arranged. On one side of the air extraction pump 17, a return pipeline 18 is fixedly connected. On the other side of the return pipeline 18, a connection end 1 is fixedly connected. On one side of the surface of the return pipeline 18, a control valve 20 is fixedly connected. On the side of the control valve 20, a liquid supplement chamber 19 is fixedly connected.

[0025] Adopting the above solution: The air extraction pump 17 re-transports the refrigerant vapor generated in the evaporator 15 back to the connection end 1 through the return pipeline 18, realizing the recycling of the refrigerant.

[0026] The compressor 4 can compress the low-temperature and low-pressure refrigerant gas and convert it into high-temperature and high-pressure gas. The solenoid valve 2 can control the capacity of the refrigerant gas entering the compressor 4. The high-temperature and high-pressure refrigerant gas then enters the condenser 7, where the refrigerant gas condenses into high-pressure liquid by releasing heat to the cooling medium.

[0027] Adopting the above solution: By compressing the low-temperature and low-pressure refrigerant gas and converting it into high-temperature and high-pressure gas, this process provides the necessary energy conditions for the subsequent condensation and evaporation of the refrigerant. At the same time, the precise control of the solenoid valve 2 ensures that the capacity of the refrigerant gas entering the compressor is appropriate, avoiding overload or insufficient situations.

[0028] The water pump 8 can pump the high-temperature water liquid into the inlet cooling tower 10 through the return water pipe 9. The water cooling tower 10 inputs the cooling water into the condenser 7 through the water pump 12. Then, the high-pressure liquid refrigerant is throttled and depressurized through the expansion valve 14, and its temperature and pressure drop sharply, turning into a low-temperature and low-pressure refrigerant liquid or a gas-liquid mixture. The low-temperature and low-pressure refrigerant enters the evaporator 15, absorbs the heat of the substance to be cooled in the evaporator 15 and vaporizes into steam, and the steam then enters the cooling chamber 16 for cooling.

[0029] Adopting the above solution: The combined action of the water pump 8 and the water cooling tower 10 provides a continuous supply of cooling water for the condenser 7, ensuring that the refrigerant gas can fully release heat and condense into a high-pressure liquid during the condensation process. Subsequently, the high-pressure liquid refrigerant is throttled and depressurized by the expansion valve 14, absorbs heat and vaporizes in the evaporator 15, achieving the cooling effect on the substance to be cooled.

[0030] The air extraction pump 17 inputs the refrigerant gas into the connection end 1 again through the return pipe 18 to form a cycle, and the liquid supplement chamber 19 supplements the refrigerant to the return pipe 18 through the control valve 20.

[0031] Adopting the above solution: The existence of the liquid supplement chamber 19 provides a necessary refrigerant supplement path for the system, ensuring the long-term stable operation of the cycle. Through the precise adjustment of the control valve 20, precise control of the liquid supplement volume can be achieved, avoiding waste and over-supplementation.

[0032] The working principle of the present utility model is as follows: First, the refrigerant gas at low temperature and low pressure enters through the connection end 1, and the solenoid valve 2 controls the capacity of its entry into the compressor 4. The compressor 4 is installed on the compressor base 5 and compresses the entering refrigerant gas, converting it into a high-temperature and high-pressure gas. Subsequently, the high-temperature and high-pressure refrigerant gas enters the condenser 7 through the gas transmission pipeline 6. In the condenser 7, the high-temperature and high-pressure refrigerant gas releases heat and condenses into a high-pressure liquid refrigerant through heat exchange with the cooling medium, usually the cooling water provided by the water cooling tower 10. In this process, the cooling water is pumped out from the water cooling tower 10 by the water pump 8 through the return pipeline 9, pressurized by the water pump 12 beside the water cooling tower base 11, and then sent back to the condenser 7 through the water transmission pipeline 13 for heat exchange. After completing the heat exchange, the cooling water flows back to the water cooling tower 10 for recycling. After the high-pressure liquid refrigerant flows out of the condenser 7, it passes through the expansion valve 14 for throttling and pressure reduction, and its temperature and pressure both drop sharply, converting into a low-temperature and low-pressure refrigerant liquid or a gas-liquid mixture. These low-temperature and low-pressure refrigerants then enter the evaporator 15, absorb the heat of the substance to be cooled in the evaporator 15 and vaporize into steam. In this process, the evaporator 15 is usually adjacent to the cooling chamber 16, and the heat in the cooling chamber 16 is absorbed by the refrigerant, thereby achieving the cooling effect. Finally, the refrigerant steam generated in the evaporator 15 is transported back to the connection end 1 along the return pipeline 18 under the action of the air extraction pump 17, forming a refrigerant cycle. On the return pipeline 18, there are a control valve 20 and a liquid replenishing chamber 19. The liquid replenishing chamber 19 replenishes the refrigerant for the system through the control valve 20 to ensure the stability and efficiency of the cycle.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
