[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] As shown in the drawing, Figures 1-4 The present application provides a cold water machine circulating filter system with modular design, which realizes efficient refrigeration, circulating filtration and easy maintenance functions through independent compressor, condenser passage, evaporator and water tank and filter. The structure of the cold water machine circulating filter system mainly comprises a rack 1, and key components such as a compressor body, a condenser 2, an evaporator body, a water tank 4 and a filter 7 installed on the rack.

[0031] The compressor body includes a first compressor 101 and a second compressor 102, which operate independently and are responsible for two refrigeration cycles respectively. This structure not only improves the refrigeration capacity of the system, but also increases the reliability and stability of the system.

[0032] The condenser 2 is provided with independent first and second condensing channels 201 and 202, each of which is equipped with an inlet and an outlet. This structure allows the high-temperature and high-pressure refrigerant gas output by the two compressors to enter the corresponding condensing channels for cooling without interfering with each other, improving the condensing efficiency. A number of cooling fans 10 are installed at the top of the condenser 2 to blow air into the condenser and enhance the cooling effect. A detachable cover 11 is provided above the cooling fans for easy cleaning and maintenance. In addition, medium injection inlet 203 and medium discharge outlet 204 are provided on the outside of the condenser to allow users to inject or discharge cooling medium as needed to adapt to different working environments and refrigeration needs.

[0033] The evaporator body includes a first evaporator 301 and a second evaporator 302, each of which is provided with a refrigerant inlet 303, a refrigerant outlet 304, a water inlet 305, and a water outlet 306. The refrigerant exchanges heat with the water inside the evaporator 3 to achieve the refrigeration effect. The water inlet 305 is connected to the water tank 4 through the filter 7 and the water pump to ensure the purity of the water entering the evaporator. The water outlet 306 is connected back to the water tank 4, forming a closed circulation system. This structure not only improves the refrigeration efficiency of the system, but also realizes the recycling and filtration of water.

[0034] The first compressor 101 and the second compressor 102 operate independently and are responsible for two refrigeration cycles respectively. The structure of the two cycle bodies is mainly as follows: the output end of the first compressor 101 is connected to the inlet of the first condensing channel 201, the outlet of the first condensing channel 201 is connected to the refrigerant inlet 303 of the first evaporator 301 through the first expansion valve 5, the refrigerant outlet 304 of the first evaporator 301 is connected to the input end of the first compressor 101, forming the first cycle body; the output end of the second compressor 102 is connected to the inlet of the second condensing channel 202, the outlet of the second condensing channel 202 is connected to the refrigerant inlet 303 of the second evaporator 302 through the second expansion valve 6, and the refrigerant outlet 304 of the second evaporator 302 is connected to the input end of the second compressor 102, forming the second cycle body.

[0035] The water tank 4 is used to store circulating water, and a filter 7 is arranged on the outer side of the water tank 4. The filter 7 is embeddedly installed on the outer side of the water tank 4, and is used to remove impurities in the water. The filter 7 has a first water outlet 701 and a second water outlet 702, which are respectively connected to the water inlets of the first evaporator 301 and the second evaporator 302 through the first water pump 8 and the second water pump 9. In order to ensure the stability and purity of the water quality, the first control valve 12 and the first water pump 8 are arranged between the first water outlet 701 and the water inlet of the first evaporator 301, and the second control valve 13 and the second water pump 9 are arranged between the second water outlet 702 and the water inlet of the second evaporator 302. By adjusting the opening degree of the control valve, the water flow entering the evaporator can be accurately controlled to meet different refrigeration requirements. At the same time, the circulating filtering effect of the filter 7 ensures the continuous stability of the water quality, prolonging the service life of the system.

[0036] When filtering, the filter 7 circulates and filters the water in the water tank 4 through the filtering medium inside it, such as activated carbon, sandstone, etc., to remove impurities and suspended solids in the water, ensuring the purity of the water entering the evaporator. Moreover, the water tank 4, filter 7, evaporator and water pump and other components jointly constitute a closed circulation system, and the flow is unidirectional. Water is continuously used in the system, which not only saves water resources, but also avoids pollution of external impurities to the system. Users can observe the water quality, replace the filtering medium in the filter 7 regularly, or adjust the opening degree of the control valve to maintain the stability and purity of the water quality.

[0037] The end of the water tank 4 away from the filter 7 is provided with a plurality of water inlets 401, which are connected to the third water pump 14 for injecting water into the water tank 4 and the third control valve 15 for controlling the water flow. This structure allows the system to supplement fresh water source as needed during operation, maintaining the stability of the water quality. At the same time, the rack 1 is also provided with an electric control box 16 for centralized control of the power supply and operation of the entire system. Various sensors, controllers and actuators are integrated inside the electric control box to realize automatic control and monitoring of the system.

[0038] The operation process of the entire system is as follows:

[0039] The refrigerant is compressed into high-temperature and high-pressure gas in the first compressor 101 or the second compressor 102, and then enters the corresponding first condensing channel 201 or the second condensing channel 202 for cooling. The cooled refrigerant is throttled and pressure-reduced by the first expansion valve 5 or the second expansion valve 6, and enters the first evaporator 301 or the second evaporator 302 to exchange heat with water. The water exchanged with heat is cooled and flows back to the water tank 4 from the water outlet 306, forming a closed circulation. At the same time, the refrigerant evaporates in the evaporator to absorb heat, and returns to the compressor again for the next cycle.

[0040] The water in the water tank 4 is pumped into the evaporator for recycling after impurities are removed by the filter 7. The recycling filtering effect of the filter 7 ensures the continuous stability of the water quality. The electric control box 16 is responsible for monitoring the running state of the whole system, ensuring the safe and efficient operation of the system.

[0041] Compared with the conventional technology, the circulating filtering system of the water chiller provided by the technical scheme forms two independent refrigeration filtering circulation structures by the cooperation of the independent compressor, the condenser 2, the evaporator 3, the water tank 4 and the filter 7, realizes the efficient operation and the circulating filtering of the system, improves the refrigeration capacity of the whole system, and increases the reliability and stability of the system. Meanwhile, the system is convenient to maintain, has strong expansibility, and is suitable for various industrial cooling, commercial refrigeration and air conditioning systems and the like occasions.

[0042] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims should be included in the present application, and any reference signs in the claims should not be regarded as limiting the claims.
