Description

[0002] Currently, refrigeration equipment generally requires anti-condensation design. This is mainly to address the trend of pursuing high energy efficiency, thin walls, metallic appearance, and embedded design. The equipment casing is more prone to excessively low temperatures due to internal cold bridging. When encountering high-temperature and high-humidity environments, its surface temperature will drop below the dew point temperature of the air, resulting in condensation. This not only affects user experience and poses safety concerns, but may also damage the electrical components and product structure within the refrigeration equipment.

[0003] In related technologies, the anti-condensation pipe of refrigeration equipment is usually connected after the condenser outlet and embedded in a pre-reserved groove in the inner lining of the refrigeration equipment. It relies on the high temperature of the compressor during operation to heat the inner lining opening and achieve the anti-condensation effect. However, the temperature of the anti-condensation pipe in this type of refrigeration equipment is relatively fixed, and it cannot automatically adjust the temperature when the ambient temperature and humidity change. For example, when the humidity increases, the condensation effect becomes relatively poor. Utility Model Content

[0024] It should be noted that, where there is no conflict, different features in the embodiments of this utility model can be combined with each other.

[0025] Currently, refrigeration equipment generally requires anti-condensation design. This is mainly to address the trend of pursuing high energy efficiency, thin walls, metallic appearance, and embedded design. The equipment casing is more prone to excessively low temperatures due to internal cold bridging. When encountering high-temperature and high-humidity environments, its surface temperature will drop below the dew point temperature of the air, resulting in condensation. This not only affects user experience and poses safety concerns, but may also damage the electrical components and product structure within the refrigeration equipment.

[0026] The inventors discovered through investigation that in related technologies, the anti-condensation pipe of refrigeration equipment is typically connected after the condenser outlet and embedded in a pre-reserved groove in the inner lining of the refrigeration equipment. It relies on the high temperature of the compressor during operation to heat the inner lining opening, thus achieving the anti-condensation effect. However, the temperature of the anti-condensation pipe in this type of refrigeration equipment is relatively fixed, and it cannot automatically adjust the temperature when the ambient temperature and humidity change. For example, when the humidity increases, the condensation effect becomes relatively poor.

[0027] In view of this, please refer to Figure 1 This utility model provides a refrigeration device 10, including a refrigeration module 100, a detection and control module 200, and an anti-condensation execution module 300.

[0028] Optionally, the refrigeration device 10 in this embodiment includes an air-cooled refrigerator.

[0029] In this embodiment, the anti-condensation execution module 300 is used to perform anti-condensation operation by adjusting the surface temperature of the condenser 120 by enhancing its heat dissipation efficiency, thereby preventing frost from forming on or around the casing of the refrigeration equipment 10. The refrigeration equipment 10 also includes an anti-condensation pipe 130, the temperature of which increases as the temperature of the condenser 120 increases, thereby realizing the anti-condensation function of the refrigeration equipment 10.

[0030] The refrigeration module 100 includes at least a compressor 110 and a condenser 120, and the refrigerant flows sequentially through the compressor 110 and the condenser 120.

[0031] In this embodiment, the refrigeration module 100 further includes a filter device 140, a capillary tube 150, and an evaporator 160, and the refrigerant forms a complete refrigeration cycle loop between the compressor 110, the condenser 120, the filter device 140, the capillary tube 150, and the evaporator 160.

[0032] The detection and control module 200 is electrically connected to the refrigeration module 100 and is used to detect the temperature and humidity of the environment and control the refrigeration module 100 to refrigerate the refrigeration equipment 10.

[0033] In this embodiment, the refrigeration device 10 detects the temperature and humidity of the environment in which the refrigeration device 10 is located through the detection and control module 200, and controls the operation of the anti-condensation execution module 300 based on the detected temperature and humidity. Specifically, when the detected ambient humidity is higher than a set value, the detection and control module 200 adjusts the execution strategy of the anti-condensation execution module 300 to increase the temperature of the condenser 120, thereby preventing its surface temperature from being too low and causing condensation.

[0034] Please refer to Figure 2 The anti-condensation execution module 300 includes at least a first fan 310 and a second fan 320. The first fan 310 is located between the compressor 110 and the condenser 120, and the second fan 320 is located on the side of the condenser 120 away from the compressor 110. The anti-condensation execution module 300 is electrically connected to the detection and control module 200. The first fan 310 and the second fan 320 are used to supply air to the condenser 120 under the control of the detection and control module 200.

[0035] In this embodiment, the first fan 310 and the second fan 320 work together to improve the heat dissipation efficiency of the condenser 120, thereby adjusting the temperature of the anti-condensation pipe 130 to meet the anti-condensation requirements. The first fan 310 can utilize the temperature of the compressor 110 to appropriately raise the temperature of the condenser 120, thereby raising the temperature of the anti-condensation pipe 130. Specifically, in a high-humidity environment, the first fan 310 and the second fan 320 operate alternately. The first fan 310 blows the heat dissipated by the compressor 110 towards the condenser 120, while the second fan 320 exhausts hot air from the other side. The two work together to achieve precise control of the heat dissipation of the condenser 120.

[0036] For example, in a high temperature and high humidity environment, the detection and control module 200 can start the first fan 310 and the second fan 320 to run alternately at maximum air volume, quickly raising the temperature of the condenser 120 to above the dew point temperature; in a low temperature and low humidity environment, only the second fan 320 can be started to run at a lower air speed, achieving a balance between energy saving and anti-condensation while ensuring basic heat dissipation.

[0037] In one possible implementation, the anti-condensation execution module 300 includes at least a first working state and a second working state.

[0038] In this embodiment, in order to achieve targeted heat dissipation and anti-condensation effects for different ambient temperature and humidity conditions where the refrigeration device 10 is located, a variety of different execution strategies can be set.

[0039] In the first operating state, the first fan 310 and the second fan 320 operate alternately; wherein, the first fan 310 is used to send the heat generated by the compressor 110 to the condenser 120.

[0040] Due to the high humidity environment, the heat required for condensation prevention in the refrigeration module 100 increases. The waste heat from the compressor 110, introduced by the first fan 310, can raise the temperature level of the condenser 120, thereby causing the temperature of the connected anti-condensation pipe 130 to rise synchronously, enhancing its ability to prevent condensation on the casing surface. Specifically, in the first operating state, the second fan 320 alternates with the first fan 310, actively transferring the residual heat generated by the compressor 110 to the condenser 120 area. The alternating operation of the two fans prevents the temperature of the condenser 120 from rising too high or too quickly.

[0041] In the second operating state, the second fan 320 continues to operate.

[0042] In normal or low-humidity environments, the system's heat dissipation and anti-condensation requirements are low, and there is no need to introduce additional waste heat from the compressor 110. Therefore, in this embodiment, by simply operating the second fan 320 to provide basic heat dissipation for the condenser 120, the basic cooling requirements can be met while reducing system energy consumption, thus achieving energy-saving operation of the refrigeration equipment 10.

[0043] In this embodiment, the detection and control module 200 analyzes data from the ambient temperature and humidity sensor to dynamically switch the anti-condensation execution module 300 between a first operating state and a second operating state. This execution strategy balances the reliability of anti-condensation in high humidity environments with the economic efficiency of operation under normal conditions.

[0044] It should be noted that, in the first and second working states, the speeds of the first fan 310 and the second fan 320 can be specifically limited according to the ambient temperature and humidity values, so as to improve the heat dissipation efficiency of the condenser 120 while saving energy.

[0045] In one possible implementation, please refer to Figure 3 The detection and control module 200 includes a detection unit 210 and a control unit 220. The detection unit 210 is responsible for collecting temperature and humidity parameters of the external environment, while the control unit 220, as the processing core, issues commands to the anti-condensation execution module 300 according to preset logic. The two work together to form a closed-loop control system.

[0046] The detection unit 210 includes at least a temperature and humidity sensor, which is used to collect the temperature and humidity values ​​of the environment in which the refrigeration device 10 is located. The temperature and humidity sensor can be set outside the refrigeration device 10, for example, it can be set on the top of the refrigeration device 10 to accurately sense the real-time temperature and humidity of the external environment.

[0047] The temperature and humidity sensor is also used to send the temperature and humidity values ​​of the environment where the refrigeration device 10 is located as a first signal to the control unit 220. The first signal can be transmitted via wired or wireless means.

[0048] The control unit 220 is electrically connected to the detection unit 210. The control unit 220 is used to receive the first signal and send a second signal to the anti-condensation execution module 300 according to the first signal to control the opening and closing of the first fan 310 and the second fan 320.

[0049] In this embodiment, the control unit 220 has preset logic and determines the execution strategy of the anti-condensation execution module 300 according to the preset logic. Specifically, the control unit 220 determines the execution strategy of the condensation execution module according to the received first signal and sends the corresponding second signal to the condensation execution module. In low temperature and low humidity or medium temperature and medium humidity environments, the second fan 320 operates normally and the fan speed corresponds to different values ​​of humidity and temperature; in high temperature and high humidity environments, the first fan 310 and the second fan 320 operate alternately.

[0050] For example, the preset logic can be as follows: when the temperature value in the first signal does not exceed 10℃ and the humidity value does not exceed 50%, the first fan 310 is kept running at a low speed; when the temperature value in the first signal is between 10℃ and 25℃ and the humidity value is between 50% and 75%, the first fan 310 is kept running at a medium speed; when the temperature value in the first signal is not lower than 25℃ and the humidity value is not lower than 75%, the first fan 310 and the second fan 320 are kept running at high speed alternately; when the temperature and humidity sensor data is abnormal three times in a row, the emergency mode is triggered, and the first fan 310 is kept running at a medium speed.

[0051] In one possible implementation, please refer to Figure 4 The refrigeration module 100 also includes a filter device 140, a capillary tube 150 and an evaporator 160, and the refrigeration unit flows sequentially through the compressor 110, the condenser 120, the filter device 140, the capillary tube 150 and the evaporator 160.

[0052] Specifically, the high-temperature and high-pressure refrigerant gas discharged from the compressor 110 is condensed and released heat in the condenser 120 to become a high-pressure liquid. Then, the refrigerant flows through the filter device 140 to remove moisture and impurities. After being depressurized through the capillary tube 150, the refrigerant becomes a low-temperature and low-pressure gas-liquid mixture. Finally, it absorbs heat and evaporates in the evaporator 160 to achieve refrigeration of the refrigeration equipment 10. After that, the refrigerant returns to the compressor 110 to complete the refrigeration cycle.

[0053] The bottom of the refrigeration equipment 10 includes a compressor compartment, and the compressor 110 and the condenser 120 are located inside the compressor compartment.

[0054] In this embodiment, the main heat-generating and vibration-generating components, such as the compressor 110 and the condenser 120, are located in the compressor compartment at the bottom of the refrigeration equipment 10, which is beneficial to the overall structural stability and sound insulation of the refrigeration equipment 10.

[0055] Optionally, the compressor 110 and condenser 120 can also be configured as external components to further improve the heat dissipation performance of the refrigeration module 100, without specific limitations here.

[0056] In one possible implementation, please refer to Figure 2 and Figure 4 The refrigeration module 100 also includes an anti-condensation pipe 130, which is connected in series between the outlet end of the condenser 120 and the inlet end of the filter device 140. The refrigerant flows sequentially through the condenser 120, the anti-condensation pipe 130 and the filter device 140 to prevent condensation on the surface of the refrigeration module 100.

[0057] In this embodiment, the anti-condensation pipe 130 is a coiled or specifically shaped pipe, typically embedded in locations such as the door frame of the refrigeration equipment 10 where the surface temperature is prone to drop due to low internal temperatures. When the high-temperature, high-pressure liquid refrigerant flowing from the condenser 120 passes through the anti-condensation pipe 130, it provides auxiliary heating to the area where it adheres, raising the surface temperature of that location above the ambient dew point temperature, thereby preventing condensation.

[0058] In one possible implementation, the temperature and humidity sensor is located outside the refrigeration device 10.

[0059] The shortest distance between the temperature and humidity sensor and the compressor 110 is greater than a set threshold.

[0060] In this embodiment, the temperature and humidity sensor is placed outside the refrigeration equipment 10 and away from heat-generating components such as the compressor 110. This allows the sensor to detect the actual temperature and humidity of the external environment, thereby driving the control unit 220 to make optimal decisions. This avoids interference from the localized high temperatures generated by the compressor 110 and condenser 120 during the operation of the refrigeration equipment 10, ensuring that the temperature and humidity sensor collects accurate external environmental parameters. Based on this data, the control unit 220 can adjust the start / stop and speed of the first fan 310 and the second fan 320, preventing condensation on the refrigeration equipment 10 while avoiding frequent start / stop of the first fan 310 and the second fan 320 due to misjudgment, thus saving energy and reducing consumption.

[0061] In one possible implementation, the set threshold is 1 meter.

[0062] This avoids the large-scale heat interference generated during the operation of compressor 110. The hot air discharged from the compressor compartment creates a localized high-temperature field, and the air temperature and humidity within this area are not accurate compared to the external environment. Maintaining a safe distance of more than one meter between the temperature and humidity sensor and compressor 110 ensures that the temperature and humidity sensor is located in an area with natural air circulation, thereby collecting temperature and humidity values ​​that represent the true state of the environment.

[0063] It should be noted that, in addition to the 1-meter threshold set in this embodiment, the threshold can also be set according to the actual size of the refrigeration equipment 10 and the position of the compressor 110. No specific limitation is made here.

[0064] In one possible implementation, the temperature and humidity sensor includes a capacitive temperature and humidity sensor.

[0065] In this embodiment, a capacitive temperature and humidity sensor is used to detect ambient temperature and humidity. The capacitive temperature and humidity sensor utilizes a miniature capacitor composed of a hygroscopic polymer dielectric, offering advantages such as high accuracy, long-term stability, low power consumption, and ease of integration. When ambient humidity changes, the polymer film adsorbs or releases water molecules, causing a change in its dielectric constant and consequently a proportional change in capacitance. An ambient temperature sensor, also integrated on the chip, is then used to detect the ambient temperature. Finally, the microprocessor processes the data and outputs the humidity and temperature values.

[0066] It should be noted that, in addition to capacitive temperature and humidity sensors, other types of sensors can also be used as temperature and humidity sensors in this embodiment, and no specific limitation is made here.

[0067] In one possible implementation, the control unit 220 further includes a main control circuit and a relay.

[0068] Optionally, the main control circuit can be a microcontroller or a programmable logic device, responsible for running the control algorithm in the preset logic. The relay, as a switching actuator, is driven by the main control circuit to control the on / off state of the first fan 310 and the second fan 320.

[0069] The temperature and humidity sensor is electrically connected to the main control circuit to continuously transmit the collected ambient temperature and humidity values ​​to the main control circuit for processing. The main control circuit is electrically connected to the first fan 310 and the second fan 320 via relays to control the start, stop, and speed of the first fan 310 and the second fan 320.

[0070] Specifically, when the main control circuit determines that the first fan 310 or the second fan 320 needs to be started according to the preset logic, it will output a low-voltage control signal to the corresponding relay coil to make the relay contacts close. The main control circuit can also control the duty cycle of the relay on and off through pulse width modulation technology, thereby realizing the start-up, shutdown and speed control of the first fan 310 or the second fan 320.

[0071] In one possible implementation, the refrigeration device 10 further includes an electrical box located on its top or back, with the main control circuitry integrated within the electrical box.

[0072] Thus, the electrical box located on the top or back of the refrigeration equipment 10 can reduce the impact of the high temperature and vibration of the compressor compartment on the lifespan and accuracy of the electronic components in the main control circuit; it also achieves physical isolation between the main control circuit and other components of the refrigeration equipment 10, improving the safety of the equipment; in addition, the integrated design of the main control circuit also facilitates centralized wiring and subsequent maintenance of the refrigeration equipment 10.

[0073] In summary, this utility model provides a refrigeration device 10, including a refrigeration module 100, a detection and control module 200, and an anti-condensation execution module 300. The refrigeration module 100 includes at least a compressor 110 and a condenser 120, with refrigerant flowing sequentially through the compressor 110 and the condenser 120. The detection and control module 200 is electrically connected to the refrigeration module 100 and is used to detect the ambient temperature and humidity and control the refrigeration module 100 to refrigerate the refrigeration device 10. The anti-condensation execution module 300 includes at least a first fan 310 and a second fan 320. The first fan 310 is located between the compressor 110 and the condenser 120, and the second fan 320 is located on the side of the condenser 120 away from the compressor 110. The anti-condensation execution module 300 is electrically connected to the detection and control module 200, and the first fan 310 and the second fan 320 are used to supply air to the condenser 120 under the control of the detection and control module 200. This solution improves the heat dissipation efficiency of the condenser 120 by having the first fan 310 and the second fan 320 work together, thereby adjusting the temperature of the anti-condensation pipe 130 to meet the anti-condensation requirements; the first fan 310 can use the temperature of the compressor 110 to appropriately increase the temperature of the condenser 120, thereby increasing the temperature of the anti-condensation pipe 130.
