Description

Technical Field

[0001] This application relates to the field of refrigeration system regulation, and in particular to a dynamic power regulation device for refrigeration systems. Background Technology

[0002] In the field of refrigeration technology, refrigeration systems have extremely wide applications, playing a vital role in people's production and daily lives, from household refrigerators and air conditioners to large-scale industrial refrigeration equipment. As people's demands for quality of life increase and industrial production places stricter demands on environmental conditions, the performance and efficiency of refrigeration systems are receiving increasing attention. Refrigeration systems must not only meet the basic requirement of lowering air temperature but also adapt to different environmental conditions, such as humidity changes, to achieve more precise and efficient cooling effects, thereby creating a more comfortable and stable environment for people.

[0003] In traditional refrigeration operations, various methods have been conventionally employed to cope with different environmental conditions. One common method is to adjust the compressor's operating frequency and power output based on the difference between the ambient temperature and the set temperature to meet refrigeration demands. Another method is to change the refrigerant flow rate, using a throttling device to control the amount of refrigerant entering the evaporator, thereby affecting the refrigeration effect. Some refrigeration systems employ a combination of multiple compressors, selectively operating different numbers based on the actual load to achieve energy savings and regulate refrigeration capacity. Furthermore, some refrigeration equipment adjusts the ventilation system by changing the fan speed to regulate air circulation, thus affecting refrigeration efficiency.

[0004] However, in environments with high humidity and high water vapor content, the refrigeration system not only has to lower the air temperature, but also increases the proportion of the total cooling capacity used for dehumidification and decreases the proportion used for cooling, ultimately resulting in a poorer cooling effect. To ensure the cooling effect, it is often necessary to increase the power of the refrigeration system. Utility Model Content

[0005] To reduce the increase in power consumption caused by high humidity, this application provides a dynamic power adjustment device for the refrigeration system.

[0006] The dynamic power adjustment device for the refrigeration system provided in this application adopts the following technical solution:

[0007] A dynamic power adjustment device for a refrigeration system includes an adjustment housing with an air inlet and an air outlet connected to different areas of the refrigeration system. A negative pressure fan is installed inside the adjustment housing. A dehumidification component is also installed inside the adjustment housing, located on the side of the negative pressure fan away from the air inlet. The dehumidification component dehumidifies the air drawn in by the negative pressure fan from the air inlet and discharges it from the air outlet.

[0008] By adopting the above technical solution, the air inlet and outlet of the regulating shell are connected to different areas of the refrigeration system. The negative pressure fan draws air in from the air inlet, and after being dehumidified by the dehumidification component, it is discharged from the air outlet. This reduces the humidity of the air in the refrigeration system and reduces the increase in refrigeration system power caused by high humidity, thus realizing dynamic adjustment of the refrigeration system power.

[0009] Preferably, the dehumidification assembly includes a condenser plate, a water collection tank, and a scraper. The condenser plate is installed inside the regulating housing, dividing the regulating housing into two areas, with the air inlet and air outlet located in different areas. A water collection port is provided at the bottom of the regulating housing, and the water collection tank is detachably installed at the water collection port of the regulating housing to collect liquid on the condenser plate. The scraper is installed at the top of the regulating housing to scrape off the condenser plate.

[0010] By adopting the above technical solution, the interior of the regulating shell is divided into two areas using a condenser plate. Air enters from the air inlet, is dehumidified by the condenser plate, and is discharged from the air outlet, thus dehumidifying the air entering the regulating shell. The water collection tank is detachably installed at the water collection port of the regulating shell to collect liquid on the condenser plate and facilitate cleaning. The water scraper is installed on the top of the regulating shell to scrape the condenser plate, which promotes the flow of condensate into the water collection tank. This reduces the need for the refrigeration system to provide a lower evaporation temperature due to high air humidity, thereby reducing the power increase caused by high humidity and improving the cooling effect.

[0011] Preferably, the wiper component includes a wiper blade and a drive component. The drive component is installed and embedded in the top of the adjustment housing. The drive component is connected to the wiper blade, and the drive component drives the wiper blade to scrape off the liquid condensed on the condenser blade.

[0012] By adopting the above technical solution, the negative pressure fan inside the regulating shell draws air in through the air inlet, the condenser plate of the dehumidification component dehumidifies the air, and the drive component of the scraper drives the scraper to scrape off the liquid condensed on the condenser plate. The liquid flows into the water collection tank and is collected, which can avoid the accumulation of liquid on the condenser plate from affecting the dehumidification effect and reduce the situation where the power of the refrigeration system increases due to high ambient humidity.

[0013] Preferably, a snap-fit ​​assembly is provided between the water collection tank and the regulating shell. The snap-fit ​​assembly includes a connecting frame, a snap-fit ​​block, and a sealing element. The connecting frame is disposed on the outer wall of the regulating shell and located at the water inlet. A snap-fit ​​groove with one closed end and one open end is formed on the side wall of the connecting frame away from the regulating shell. The snap-fit ​​groove is a dovetail groove. The snap-fit ​​block can be inserted into the snap-fit ​​groove. The end of the snap-fit ​​block away from the connecting frame is connected to the water collection tank. The sealing element is disposed on the side of the water collection tank near the regulating shell. The sealing element is used to seal the gap between the water collection tank and the regulating shell.

[0014] By adopting the above technical solution, the negative pressure fan inside the regulating shell draws air in from the air inlet, dehumidifies it through the dehumidification component, and then discharges it to different areas of the refrigeration system from the air outlet, which can reduce the power increase of the refrigeration system due to handling high humidity air; the condenser plate in the dehumidification component condenses and dehumidifies the air, the water collection tank collects the condensate, and the scraper removes the liquid on the condenser plate; the connecting frame and the snap-fit ​​block of the snap-fit ​​component cooperate to connect the water collection tank to the regulating shell, the dovetail-shaped snap-fit ​​slot facilitates the insertion of the snap-fit ​​block and ensures a stable connection, and the sealing component can seal the gap between the water collection tank and the regulating shell to prevent liquid leakage and ensure the airtightness of the regulating shell except for the air inlet and air outlet.

[0015] Preferably, the sealing element includes at least four active sealing strips, and the active sealing strips are disposed on the top wall of the water collection tank near the regulating shell, and the active sealing strips are disposed along the groove of the water collection tank to surround the groove of the water collection tank.

[0016] By adopting the above technical solution, the air inlet and outlet on the regulating shell are connected to different areas of the refrigeration system. The negative pressure fan inside the regulating shell draws in air from the air inlet, and the dehumidification component dehumidifies the air and discharges it from the air outlet, which can reduce the increase in refrigeration system power caused by high humidity. The condenser plate of the dehumidification component divides the regulating shell into two areas. The water collection tank collects the liquid on the condenser plate, and the scraper removes the liquid from the condenser plate, which helps the dehumidification work. The snap-fit ​​component connects the water collection tank to the regulating shell, and multiple active sealing strips are set around the groove of the water collection tank to effectively seal the gap between the water collection tank and the regulating shell.

[0017] Preferably, the sealing element further includes at least one passive sealing positioning strip, which is disposed at the bottom of the connecting frame near the water collection tank. The top wall of the water collection tank has a positioning groove for the passive sealing positioning strip to be embedded in, and the passive sealing positioning strip is located on the side of the water collection tank near the closed end of the connecting groove.

[0018] By adopting the above technical solutions, the configuration of the regulating shell, air inlet, air outlet, negative pressure fan, and dehumidification components allows the surrounding air of the refrigeration system to be drawn in, dehumidified, and then discharged, reducing the increase in power consumption caused by high humidity. The configuration of the condenser plate, water collection tank, and scraper allows the condenser plate to condense water vapor in the air, the water collection tank to collect condensate, and the scraper to remove liquid from the condenser plate. The connecting frame and snap-fit ​​block of the snap-fit ​​component enable the snap-fit ​​between the water collection tank and the regulating shell, and the active sealing strip of the sealing component can seal the gap between the water collection tank and the regulating shell. The configuration of the passive sealing locking strip and locking groove can further enhance the sealing effect between the water collection tank and the regulating shell, while ensuring the connection stability between the water collection tank and the regulating shell, better guaranteeing the dehumidification effect, and further reducing the increase in power consumption of the refrigeration system caused by high humidity.

[0019] Preferably, the water collection tank has a guide slope on the side near the positioning slot, and the guide slope is used to guide the passive sealing positioning strip into the positioning slot.

[0020] By adopting the above technical solution, during the installation of the water collection tank, the guide slope can guide the passive sealing locking strip to smoothly enter the locking groove, which facilitates the installation of the water collection tank and the regulating shell.

[0021] Preferably, the regulating shell is also equipped with a humidity monitoring component at the air inlet. The humidity monitoring component is used to monitor the humidity of the air around the refrigeration system. When the humidity of the air around the refrigeration system exceeds a preset humidity threshold, the negative pressure fan and dehumidification component are controlled to start to dehumidify the air.

[0022] By adopting the above technical solution, the humidity monitoring component can monitor the air humidity around the refrigeration system. When the humidity exceeds the preset threshold, it controls the negative pressure fan and dehumidification component to start, dehumidify the air, and reduce the increase in power caused by high humidity.

[0023] Preferably, the humidity monitoring component includes a humidity monitoring sensor and a controller. The humidity monitoring sensor is installed at the air inlet of the regulating shell, and the controller is installed on the regulating shell. The monitoring sensor, the negative pressure fan, and the dehumidification component are all electrically connected to the controller. The humidity monitoring sensor is used to monitor the humidity of the air around the refrigeration system and send the humidity signal to the controller. When the humidity of the air around the refrigeration system exceeds a preset humidity threshold, the controller controls the negative pressure fan and the dehumidification component to start.

[0024] By adopting the above technical solution, the humidity monitoring sensor can monitor the air humidity around the refrigeration system and transmit the signal to the controller. When the humidity exceeds the preset threshold, the controller controls the negative pressure fan and dehumidification components to start, thereby realizing automatic dehumidification of the air around the refrigeration system and reducing the increase in refrigeration system power caused by high humidity.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The air inlet and outlet of the regulating shell are connected to different areas of the refrigeration system. The negative pressure fan draws air in from the air inlet, and after being dehumidified by the dehumidification component, it is discharged from the air outlet. This can reduce the humidity of the air in the refrigeration system and reduce the increase in refrigeration system power caused by high humidity, thus realizing dynamic adjustment of the refrigeration system power.

[0027] 2. The condenser plate divides the interior of the regulating housing into two areas, allowing air to enter through the air inlet, be dehumidified by the condenser plate, and then be discharged through the air outlet, thus dehumidifying the air entering the regulating housing. The water collection tank is detachably installed at the water collection port of the regulating housing, collecting liquid on the condenser plate for easy cleaning. The scraper is installed on the top of the regulating housing to scrape the condenser plate, promoting the flow of condensate into the water collection tank. This reduces the need for the refrigeration system to provide a lower evaporation temperature due to high humidity, thereby reducing the power increase caused by high humidity and improving the cooling effect.

[0028] 3. The humidity monitoring sensor can monitor the humidity of the air around the refrigeration system and transmit the signal to the controller.

[0035] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0036] This application discloses a dynamic power adjustment device for a refrigeration system. (Refer to...) Figure 1The refrigeration system power dynamic adjustment device includes an adjustment shell 1, a negative pressure fan 2, a dehumidification component 3, and a humidity monitoring component 5. The adjustment shell 1 has an air inlet 11 and an air outlet 12, which are respectively connected to different areas of the refrigeration system. The negative pressure fan 2 is installed inside the adjustment shell 1. The air inlet of the negative pressure fan 2 is connected to the air inlet 11 of the adjustment shell 1, and the air outlet of the negative pressure fan 2 is connected to the air outlet 12 of the adjustment shell 1.

[0037] The dehumidification component 3 is located on the side of the negative pressure fan 2 away from the air inlet 11, and the humidity monitoring component 5 is set at the air inlet 11 on the regulating shell 1. This setting allows the humidity monitoring component 5 to monitor the air humidity around the refrigeration system in real time. When the humidity exceeds the preset threshold, it controls the negative pressure fan 2 and the dehumidification component 3 to start, drawing the air around the refrigeration system into the regulating shell 1 for dehumidification, and then discharging it to the surrounding area of ​​the refrigeration system, thus reducing the increase in refrigeration system power caused by high humidity.

[0038] Reference Figure 1 The regulating housing 1 is the main structure of the entire device, providing installation space and protection for internal components. The air inlet 11 and air outlet 12 of the regulating housing 1 can be circular or square openings. The air inlet 11 draws in undehumidified air from the vicinity of the refrigeration system that exceeds the humidity threshold, while the air outlet 12 discharges dehumidified air back to the vicinity of the refrigeration system, and is located close to the air inlet of the refrigeration system. The placement of the air inlet 11 and air outlet 12 must consider the airflow path to ensure smooth airflow within the regulating housing 1. A negative pressure fan 2 is installed inside the regulating housing 1 to generate suction, drawing air from the vicinity of the refrigeration system into the regulating housing 1 through the air inlet 11. The negative pressure fan 2 can be a centrifugal fan or an axial flow fan.

[0039] The humidity monitoring component 5 includes a humidity monitoring sensor 51 and a controller. The humidity monitoring sensor 51 is installed at the air inlet 11 of the regulating housing 1. The humidity monitoring sensor 51 can be a capacitive humidity sensor or a resistive humidity sensor; in this embodiment, a capacitive humidity sensor is used. The controller is installed on the regulating housing 1; in this embodiment, the controller is a PLC controller. The monitoring sensor, the negative pressure fan 2, and the dehumidification component 3 are all electrically connected to the controller. The humidity monitoring sensor 51 is used to monitor the humidity of the air around the refrigeration system and send the humidity signal to the controller. When the humidity of the air around the refrigeration system exceeds a preset humidity threshold, the controller controls the negative pressure fan 2 and the dehumidification component 3 to start and dehumidify the air.

[0040] Reference Figure 1 and Figure 2Air exceeding the humidity threshold is drawn into the regulating housing 1 through the air inlet 11 by the negative pressure fan 2, and then discharged to the dehumidification assembly 3 for dehumidification via the air outlet 12 of the negative pressure fan 2. The dehumidification assembly 3 includes a condenser plate 31, a water collection tank 32, and a scraper 33. The condenser plate 31 is installed inside the regulating housing 1, dividing the regulating housing 1 into two areas, with the air inlet 11 and the air outlet 12 located in different areas. When air containing water vapor passes through the condenser plate 31, the water vapor condenses into water droplets on the surface of the condenser plate 31 upon cooling.

[0041] The wiper component 33 includes a wiper blade 331 and a drive component 332. The drive component 332 is embedded in the top of the adjusting housing 1 and is connected to the wiper blade 331. In this embodiment, the drive component 332 employs a motor and a linkage mechanism, which is connected to the wiper blade 331 to drive the wiper blade 331 to slide on the surface of the condensation plate 31, scraping away the condensed liquid on the condensation plate 31 and making it easier for water droplets to flow into the water collection tank 32. The wiper blade 331 is generally made of rubber or silicone, which have good flexibility and wiping effect.

[0042] Reference Figure 2 and Figure 3 The water collection tank 32 is used to collect water condensed on the condenser plate 31. The inner bottom wall of the regulating shell 1 is inclined downwards towards the water collection tank 32 so that the liquid can flow smoothly into the water collection tank 32. A snap-fit ​​assembly 4 is provided between the water collection tank 32 and the regulating shell 1. The water collection tank 32 is detached and installed on the regulating shell 1 through the snap-fit ​​assembly 4. The snap-fit ​​assembly 4 includes a connecting frame 41, a snap-fit ​​block 42, and a sealing element 43. The connecting frame 41 is integrally formed on the outer wall of the regulating shell 1 and is located at the water inlet 13. A snap-fit ​​groove 411 with one end closed and the other end open is opened on the side wall of the connecting frame 41 away from the regulating shell 1. The snap-fit ​​groove 411 is a dovetail groove. The snap-fit ​​block 42 can be inserted into the snap-fit ​​groove 411. The end of the snap-fit ​​block 42 away from the connecting frame 41 is integrally formed on the water collection tank 32. This dovetail groove snap-fit ​​method makes the water collection tank 32 firmly installed and not easy to fall off.

[0043] Reference Figure 3 , 45. A sealing element 43 is disposed on the side of the water collection tank 32 near the adjusting shell 1 to seal the gap between the water collection tank 32 and the adjusting shell 1. The sealing element 43 includes at least four active sealing strips 431 and at least one passive sealing locking strip 432. Multiple active sealing strips 431 are glued to the top wall of the water collection tank 32 near the adjusting shell 1, arranged along the opening of the water collection tank 32 to surround the opening of the water collection tank 32. The active sealing strips 431 can be made of rubber, possessing good elasticity and sealing performance. In this embodiment, a pair of active sealing strips 431 aligned with the installation direction of the water collection tank 32 are located between the top wall of the water collection tank 32 and the bottom wall of the connecting frame 41, and another pair of active sealing strips 431 are located between the top wall of the water collection tank 32 and the side wall of the connecting frame 41.

[0044] The passive sealing locking strip 432 is glued to the bottom of the connecting frame 41 near the water collection tank 32. A locking groove 321 for the passive sealing locking strip 432 is provided on the top wall of the water collection tank 32. The passive sealing locking strip 432 is located on the side of the water collection tank 32 near the closed end of the locking slot 411. A guide slope 322 is provided on the side of the water collection tank 32 near the locking groove 321 to guide the passive sealing locking strip 432 into the locking groove 321, facilitating the installation of the water collection tank 32. During installation, the locking block 42 end on the side of the water collection tank 32 with the guide slope 322 is inserted into the locking slot 411.

[0045] The implementation principle of the dynamic power adjustment device for a refrigeration system according to this application embodiment is as follows: The humidity monitoring component 5 monitors the humidity of the air surrounding the refrigeration system in real time. When the humidity exceeds a preset threshold, the controller controls the negative pressure fan 2 to start, drawing the air around the refrigeration system into the regulating shell 1 through the air inlet 11. When the air passes through the condenser plate 31 in the regulating shell 1, water vapor condenses into water droplets on the surface of the condenser plate 31 upon cooling. The water scraper 33 scrapes the water droplets off the condenser plate 31, causing them to flow into the water collection tank 32. The dehumidified air is discharged into the refrigeration system through the air outlet 12, thereby reducing the humidity of the air around the refrigeration system, reducing the increased power consumption of the refrigeration system due to high humidity, and realizing dynamic power adjustment of the refrigeration system.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
