Description

Technical Field

[0001] This utility model relates to the field of industrial temperature control equipment technology, and in particular to an integrated chiller unit. Background Technology

[0002] In existing technologies, chiller units are common refrigeration equipment, often used as auxiliary equipment to produce chilled water for cooling other equipment or production processes. Their applications are very wide-ranging: in the rubber and plastics industry, they are used for cooling and temperature control of injection molding machines, vacuum forming machines, extruders, blow molding machines, and rubber mixing mills; in the electronics industry, they are used for cooling and temperature control of laser equipment, ultrasonic cleaning equipment, and electronic component manufacturing equipment; in the chemical industry, they are used for cooling and temperature control of reaction vessels, condensers, and distillation towers; in the food industry, they are used for cooling and temperature control of food processing equipment, milk rapid cooling processes, and fruit and wine production processes; and in the pharmaceutical industry, they are used for cooling and temperature control of pharmaceutical equipment, medical equipment, and laboratory equipment. In general refrigeration equipment, the refrigeration system and the cooling medium circulation system are separate, requiring on-site installation of water circulation pipelines. Even if integrated chiller units exist, they are typically small chiller units below 40HP.

[0003] Chinese utility model patent application number 201921338268.0 discloses an integrated chiller unit combining evaporative refrigeration and mechanical refrigeration, including a housing and mechanical refrigeration components and evaporative refrigeration components disposed within the housing. The housing is divided into an evaporative cooling chamber and an equipment chamber. The mechanical refrigeration component includes a compressor, a first evaporative heat exchanger, a throttling element, and an evaporator. The evaporative refrigeration component includes a water collector, a water pump, a water distributor, a fan, and a second evaporative heat exchanger. The first and second evaporative heat exchangers are disposed inside the evaporative cooling chamber. The water distributor is disposed at the top of the first and second evaporative heat exchangers. The water collector is disposed at the bottom of the first and second evaporative heat exchangers. The water pump is disposed on the water pipe between the water distributor and the water collector. The fan is disposed at the top of the housing. The compressor, evaporator, and control box are disposed at the bottom of the housing. However, in this type of integrated chiller unit that combines evaporative refrigeration and mechanical refrigeration, the refrigeration system and the cooling medium circulation system are separate, requiring on-site installation of water circulation pipes, resulting in low installation efficiency. Furthermore, since it adopts an integrated refrigeration structure, if one of the refrigeration components is damaged, it will affect the overall normal operation of the equipment. In addition, its power cannot reach 100HP, limiting its application scenarios. Summary of the Invention

[0023] An integrated water chiller unit includes a body 1 mounted on the ground, and further includes a refrigeration module for forming a parallel refrigeration structure, a media circulation module for forming an internal cooling structure, and an electronic control module for forming a monitoring and protection structure. The refrigeration module is arranged inside the body 1 on one side, the media circulation module is arranged adjacent to the refrigeration module, and the electronic control module is configured between the media circulation module and the refrigeration module. A schematic diagram of the overall structure of this utility model is shown below. Figure 1 As shown.

[0024] The refrigeration module includes a compressor 2, a condenser 3, and an evaporative cooler 4. The compressor 2 is located at the bottom inner side of the body 1 and is fixedly connected to the body 1. The discharge side of the compressor 2 is connected to the input end of the condenser 3. The condenser 3 is located at the top inner side of the body 1 and is fixedly connected to the body 1, corresponding to the compressor 2. The evaporative cooler 4 is located at the bottom of the body 1 and is fixedly connected to the body 1, corresponding to the compressor 2. The input and output ends of the evaporative cooler 4 are connected to the output end of the condenser 3 and the suction side of the compressor 2, respectively. There are three sets of refrigeration modules, which are arranged adjacent to each other inside the body 1, and each set of refrigeration modules is set independently. The refrigeration module, through the cooperation of compressor 2, condenser 3, and evaporative cooler 4, forms a refrigeration structure to cool the water in the medium circulation module. Compressor 2 compresses the low-temperature, low-pressure gaseous refrigerant from evaporative cooler 4 to discharge high-temperature, high-pressure gaseous refrigerant. Condenser 3 condenses the high-temperature, high-pressure gaseous refrigerant to form liquid refrigerant. Evaporative cooler 4 cools the water by exchanging heat with the liquid refrigerant and discharges the low-temperature, low-pressure gaseous refrigerant into compressor 2, forming a refrigerant circulation channel. A schematic diagram of the refrigeration module and body 1 is shown below. Figure 2 As shown.

[0025] It also includes a cooling fan 5, which is located on the top of the body 1 and fixedly connected to the body 1, corresponding to the condenser 3. The cooling fan 5 is arranged in relation to the condenser 3.

[0026] It also includes a dryer filter 6 and an expansion valve 7, which are sequentially assembled on the pipeline between the condenser 3 and the evaporator 4. The dryer filter 6 is used to filter impurities and absorb residual moisture in the refrigerant to protect the refrigeration system. The expansion valve 7 is used to reduce the pressure of the high-temperature, high-pressure liquid refrigerant from the condenser 3 to a low-temperature, low-pressure mist-like refrigerant through a throttling orifice. The working principle diagram of this utility model is shown below. Figure 3 As shown.

[0027] The media circulation module includes a chilled water return port 8, a buffer tank 9, a circulating water pump 10, and a chilled water outlet 11. The chilled water return port 8 is located on the evaporative cooler 4 and is connected to the inlet of the evaporative cooler 4. The buffer tank 9 is located on the lower inner side of the body 1 and is fixedly connected to the body 1. The outlet of the evaporative cooler 4 is connected to the buffer tank 9 through a pipeline. The circulating water pump 10 is located at the lower part of the body 1 and is fixedly connected to the body 1. The input end of the circulating water pump 10 is connected to the buffer tank 9. The chilled water outlet 11 is located at the output end of the circulating water pump 10. It is connected to the output end of the circulating water pump 10. The medium circulation module cooperates with the chilled water return port 8, the buffer water tank 9, the circulating water pump 10 and the chilled water outlet 11 to form the medium circulation structure in the integrated chiller. The chilled water return port 8 is used as the return water structure on the evaporative cooler 4 to meet the return water requirements of the chilled water. The buffer water tank 9 is used to store the chilled water after it has been frozen by the evaporative cooler 4. The circulating water pump 10 is used to discharge the chilled water in the buffer water tank 9 into the machine body 1. The chilled water outlet 11 is used as the outlet structure on the circulating water pump 10.

[0028] It also includes a water tank level gauge 12, which is installed on one side of the buffer water tank 9 and fixedly connected to the buffer water tank 9. The water tank level gauge 12 is used to display the remaining water volume in the buffer water tank 9 in real time.

The electrical control box 13 is located on the lower side of the body 1 and is fixedly connected to the body 1. A protection alarm is installed inside the electrical control box 13. The refrigeration protection component is assembled in the refrigeration module, and the circulation protection component is assembled in the medium circulation module. The electrical control module, through the cooperation of the electrical control box 13, the refrigeration protection component, and the circulation protection component, constitutes an electrical control structure with protection functions. The electrical control box 13 is used to control the integrated chiller, the refrigeration protection component is used to protect the refrigeration module, and the circulation protection component is used to protect the medium circulation module.

[0030] The refrigeration protection assembly includes an exhaust pressure controller 14, an exhaust pressure indicator 15, a return gas pressure indicator 16, a high-pressure protector 17, and a low-pressure protector. The exhaust pressure controller 14 is mounted on the pipeline connecting the exhaust side of the compressor 2 to the condenser 3. The exhaust pressure indicator 15 and the high-pressure protector 17 are sequentially mounted on the pipeline connecting the output end of the condenser 3 to the dryer filter 6. The return gas pressure indicator 16 and the low-pressure protector are sequentially mounted on the pipeline connecting the output end of the evaporator 4 to the suction side of the compressor 2. The refrigeration protection assembly, through the cooperation of the exhaust pressure controller 14, the exhaust pressure indicator 15, the return gas pressure indicator 16, the high-pressure protector 17, and the low-pressure protector, protects the refrigeration module. Specifically, the exhaust pressure controller 14 is used for high-pressure protection of the condenser 3, the exhaust pressure indicator 15 is used to display the pressure of the gas discharged from the condenser 3, the return gas pressure indicator 16 is used to display the pressure of the gaseous refrigerant discharged from the evaporator 4 into the compressor 2, and the high-pressure protector 17 and the low-pressure protector are used to prevent damage to the equipment due to abnormal pressure.

[0031] The circulation protection component includes a water flow protector 19, a water tank level protector 20, and a target-type flow switch 21. The water flow protector 19 is installed on the pipeline connecting the outlet of the evaporative cooler 4 to the buffer water tank 9. The water tank level protector 20 is located inside the buffer water tank 9 and is fixedly connected to it. The target-type flow switch 21 is installed at the chilled water outlet 11. The circulation protection component, through the cooperation of the water flow protector 19, the water tank level protector 20, and the target-type flow switch 21, protects the medium circulation module. Specifically, the water flow protector 19 is used to monitor the water flow status and trigger system protection actions when the water flow is abnormal. The water tank level protector 20 is used to monitor and control the water tank level to prevent equipment damage caused by excessively high or low water levels. The target-type flow switch 21 is used to monitor the water flow status to achieve equipment protection and control.

[0032] The electrical control components in the cooling protection component and the circulation protection component are all electrically connected to the electrical control box 13. The working principle and assembly method of each protection device are existing technologies, so they will not be described in detail here.

[0033] Working principle:

[0034] The circulating water pump 10 draws water from the buffer tank 9 into the evaporative cooler 4 for heat exchange, and then returns to the buffer tank 9, forming an internal medium circulation. The compressor 2, condenser 3, expansion valve 7, and evaporative cooler 4 in the refrigeration module form a refrigerant circulation channel. The high-temperature and high-pressure gaseous refrigerant discharged by the compressor 2 enters the condenser 3 to dissipate heat and condense into liquid refrigerant. After flowing through the dryer filter 6, it passes through the expansion valve 7 and is throttled into low-temperature and low-pressure liquid refrigerant. It then enters the evaporative cooler 4 to absorb heat from the water to be cooled and completely evaporates and vaporizes, before returning to the suction port of the compressor 2. This cycle continues. During operation, the protection devices in the integrated chiller monitor the working status of the refrigeration module and the medium circulation module in real time to ensure the normal operation of the equipment. The three sets of refrigeration modules in the integrated chiller are independent of each other and form a backup relationship. The failure of any one refrigeration module will not affect the normal operation of the other two sets of refrigeration modules. Furthermore, due to the linkage of the three sets of refrigeration modules, the power of this integrated chiller can reach 100HP.

[0035] The beneficial effects of this utility model are that it is equipped with a refrigeration module, which consists of multiple refrigeration systems, each of which operates independently and serves as a backup for each other. If one refrigeration system fails, it will not affect the normal operation of the other refrigeration systems. The medium circulation module and the refrigeration module adopt an integrated design, eliminating the need for on-site water circulation pipeline installation, making installation and use convenient. No external hydraulic module is required, and its power can reach 100HP, making it widely applicable. It is also equipped with an electrical control module, which can work with multiple sets of protection devices through the electrical control box to monitor and protect the unit's operating status, ensuring the normal operation of the unit.

[0036] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
