Abstract
Description
Technical Field
[0001] This application relates to the field of refrigeration, and in particular to an adjustable refrigeration device. Background Technology
[0002] Traditional refrigeration systems typically employ multiple sets of solenoid valves and multi-segment capillary tubes to maintain a fixed evaporation temperature and meet varying cooling energy demands. Excess cooling capacity must be offset by a heater. Disadvantages include: 1. Limited to fixed evaporation temperatures; 2. Inability to automatically adjust evaporation temperature based on actual dynamic cooling capacity; 3. Excess energy can only be offset by a heater; 4. High energy consumption; 5. Numerous components, increasing installation difficulty; 6. Numerous components, making installation time-consuming and labor-intensive. Utility Model Content
[0003] To facilitate automatic adjustment of the evaporation temperature based on actual dynamic cooling capacity, simplify installation, reduce device components, and shorten installation time, this application provides an adjustable refrigeration device.
[0004] This application provides an adjustable refrigeration device, which adopts the following technical solution:
[0005] An adjustable refrigeration device includes an evaporator, a compressor, a condenser, and a solenoid valve disposed between the condenser and the evaporator. The evaporator outlet is provided with a first pipe, the end of which is away from the evaporator is connected to the compressor intake port. The compressor exhaust port is provided with a second pipe, the end of which is away from the compressor is connected to the condenser inlet. The condenser outlet is provided with a third pipe, the end of which is away from the condenser is connected to the solenoid valve inlet. The solenoid valve outlet is provided with a fourth pipe connected to the evaporator inlet. An adjustment component is provided on the fourth pipe.
[0006] By adopting the above technical solution, the compressor compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant, which is then discharged through the exhaust port. The high-temperature, high-pressure gaseous refrigerant enters the condenser, where it releases heat and condenses into a liquid state. The high-temperature, high-pressure liquid refrigerant then enters the regulating component through a solenoid valve, where it is depressurized and cooled, becoming a low-temperature, low-pressure liquid refrigerant. The low-temperature, low-pressure liquid refrigerant enters the evaporator, where it absorbs heat and evaporates into a gaseous state. The low-temperature, low-pressure gaseous refrigerant flows out of the evaporator and enters the compressor's suction port through a pipeline, where it is drawn in and compressed again.
[0007] Preferably, the regulating component includes a valve body disposed on the pipe four, a valve needle disposed within the valve body, and a drive motor for driving the valve needle to control the flow rate of the valve body. The valve body has a fluid hole communicating with the pipe four, the valve needle is located within the fluid hole, and the drive motor is used to drive the valve needle to control the flow rate within the fluid hole.
[0008] By adopting the above technical solution, the drive motor drives the valve needle to control the flow rate in the valve body, thereby facilitating the automatic adjustment of the evaporation temperature according to the actual dynamic cooling capacity.
[0009] Preferably, the compressor is equipped with a gas-liquid separator at its air intake.
[0010] By adopting the above technical solution, the gas-liquid separator is used to separate the liquid and gaseous portions of the refrigerant, preventing liquid refrigerant from entering the compressor.
[0011] Preferably, the third pipe is equipped with a drying filter.
[0012] By adopting the above technical solution, the dryer filter is used to remove moisture and impurities from the refrigerant, thereby extending the service life of the refrigerant.
[0013] In summary, this application allows for adjustment of the evaporation temperature according to actual needs, effectively reducing the number of accessories, lowering equipment costs, reducing installation difficulty, and improving installation efficiency. The flow rate through the flow orifice on the valve body is controlled by controlling the rotation of the valve needle via the drive motor, thereby controlling the actual evaporation temperature. When the refrigerant enters the valve body, the flow rate increases sharply due to the narrowing of the channel, causing a sudden drop in pressure. The refrigerant changes from a high-pressure liquid to a low-pressure liquid, and its temperature also drops significantly due to the reduced pressure. At this point, the low-temperature, low-pressure refrigerant liquid enters the evaporator. Inside the evaporator, the refrigerant absorbs heat from the surrounding environment and evaporates, further reducing the refrigerant temperature and achieving a cooling effect.

[0016] The following is in conjunction with the appendix Figure 1 The present invention will be further described below. The following embodiments are only used to more clearly illustrate the technical solution of this application, and should not be used to limit the protection scope of the present invention.
[0017] In the description of this application, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0018] This application discloses an adjustable cooling device. (Refer to...) Figure 1 The system includes an evaporator 1, a pipe 5 connected at one end to the outlet of the evaporator 1, a compressor 2 connected at the other end of the pipe 5, a pipe 6 connected at one end to the exhaust port of the compressor 2, a condenser 3 connected at the other end of the pipe 6, a pipe 7 connected at one end to the outlet of the condenser 3, a solenoid valve 4 connected at the other end of the pipe 7, a pipe 8 connected at one end to the outlet of the solenoid valve 4 and to the inlet of the evaporator 1, and an adjusting assembly 9 installed on the pipe 8. The suction port of the compressor 2 is connected to the pipe 5. The compressor 2 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. The high-temperature, high-pressure gaseous refrigerant flows out from the exhaust port of the compressor 2 and enters the condenser 3, where it releases heat and condenses into a liquid state. At this time, the high-temperature, high-pressure liquid refrigerant enters the regulating component 9 through the solenoid valve 4. The regulating component 9 reduces the pressure and temperature, forming a low-temperature, low-pressure liquid refrigerant. The low-temperature, low-pressure liquid refrigerant enters the evaporator 1 through pipe 4 8 from the inlet of the evaporator 1. Inside the evaporator 1, it absorbs heat and evaporates into a gaseous state, forming a low-temperature, low-pressure gaseous refrigerant that flows out from the outlet of the evaporator 1 and enters the suction port of the compressor 2 through pipe 5. It is then sucked into the compressor 2 and compressed again, thus completing the cycle. This application eliminates multiple capillary tubes, effectively reducing the number of accessories and lowering the cost of the device; the evaporation temperature can be dynamically adjusted through the regulating component 9 without increasing energy consumption, thus improving energy efficiency.
[0019] Reference Figure 1 The regulating component 9 includes a valve body 91 mounted on pipe 4 8, a valve needle 92 mounted inside the valve body 91, and a drive motor 93. The valve body 91 has a fluid orifice 10 communicating with pipe 4 8. The drive motor 93 controls the valve needle 92 to open and close the fluid orifice 10 and controls the flow rate of the fluid orifice 10. The output shaft of the drive motor 93 is connected to the valve needle 92 via a coupling. In this embodiment, a controller is provided, electrically connected to the drive motor 93. The controller can control the drive motor 93 to activate the valve needle 92, thereby controlling the flow rate within the fluid orifice 10, thus facilitating the adjustment of the evaporation temperature by the operator.
[0020] Reference Figure 1In this embodiment, pipe 8 is made of copper, which has good corrosion resistance and thermal conductivity. A gas-liquid separator is installed at the suction port of compressor 2. The gas-liquid separator is used to separate the liquid and gaseous portions of the refrigerant, effectively reducing the possibility of liquid refrigerant entering compressor 2 and affecting its operation. A dryer filter is also installed on pipe 7. The dryer filter is used to remove moisture and impurities from the refrigerant, extending the service life of the refrigerant. It can also reduce the possibility of impurities clogging the solenoid valve 4 and regulating assembly 9, thus affecting their operation.
[0021] This application can effectively control the evaporation temperature by adjusting component 9, reducing energy waste and improving the environmental performance of the device; at the same time, this application has fewer structural components, is easy to install, and effectively improves the installation efficiency of the device.
[0022] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
