Description

Technical Field

[0001] This article relates to a refrigeration device based on modular design. Background Technology

[0002] In industrial production, refrigeration units in workshops are key equipment for ensuring a stable production environment. Most existing workshop refrigeration units adopt a decentralized layout, meaning that core components such as compressors, condensers, and evaporators are installed in different locations within the workshop, connected by long pipelines.

[0003] This decentralized layout presents several problems: First, the exposed pipelines are susceptible to damage from workshop dust and mechanical impacts, and the complex pipelines occupy a lot of space, resulting in a cluttered workshop environment. Second, the installation and commissioning process is cumbersome, requiring the calibration of the connection accuracy of each component individually, which is inefficient. Third, maintenance is difficult; when equipment malfunctions, each of the decentralized components must be checked one by one, increasing maintenance costs and downtime. Fourth, energy utilization is low; the heat dissipation efficiency of the decentralized condensers is unstable, and centralized recovery of waste heat cannot be achieved.

[0004] Modular design, by integrating core components, can effectively solve the above problems and has become an important direction for the development of refrigeration equipment. Utility Model Content

[0005] This utility model aims to provide a refrigeration device based on modular design, effectively solving problems such as inconvenient maintenance, scattered installation, impact on the aesthetics of the workshop, and installation of other components in the existing structure. The specific solution is as follows:

[0006] A modularly designed refrigeration unit includes an internal evaporator and an external integrated outdoor unit. The evaporator can be installed in various designated locations within the workshop as needed. The integrated outdoor unit can be installed nearby outside the workshop.

[0007] The integrated outdoor unit includes a frame body, which is a modular integrated core structure, including a bottom frame, side panels, a top panel, and side air-cooling equipment. The side panels have air intake grilles to introduce cooling air into the air-cooling equipment.

[0008] The condenser and air-cooled unit are fixed at both ends of the bottom frame, and multiple compressors are installed in the space between them to achieve centralized compression and pressurization of the refrigerant. The upper surface of the bottom frame has a horizontal main pipeline.

[0009] The main pipeline has multiple connection ports, including refrigerant outlet, refrigerant inlet, hot water pipe and cold water pipe. Each connection port is connected to the compressor's air inlet. The refrigerant outlet is connected to the condenser, the refrigerant inlet is connected to the main pipeline, and the hot water pipe and cold water pipe are both connected to the condenser, thereby achieving centralized distribution of refrigerant.

[0010] To further extend the service life of the integrated outdoor unit, the bottom frame, side panels, and top plate of the main frame are all made of stainless steel with an anti-corrosion coating. This stainless steel frame and anti-corrosion coating significantly improve the service life of the integrated outdoor unit.

[0011] To facilitate refrigerant delivery and the addition or removal of compressors, the main pipeline is made of copper with a diameter of 50-80mm. A sealing joint is provided at the connection point, and the sealing joint is connected to the compressor's inlet end via a flange.

[0012] To facilitate cooling and temperature control in different parts of the workshop, the device includes multiple evaporators. The evaporators are connected to the refrigerant outlet and inlet pipes on the integrated outdoor unit via flexible pipes. The number of compressors is equal to the number of evaporators.

[0013] Furthermore, an electronic expansion valve is installed between the condenser and the refrigerant outlet pipe. This electronic expansion valve is mounted on top of the condenser and is used to regulate the refrigerant flow rate into the evaporator. The electronic expansion valve allows for setting the refrigerant flow rate, thus adapting to different numbers of evaporators and improving the gas-liquid mixing of the refrigerant.

[0014] To further extend the service life of the compressor, the refrigerant inlet pipe is connected to the main pipeline after passing through a gas-liquid separator.

[0015] Beneficial effects:

[0016] 1. Modular integration and simplified structure: Core components such as condensers, multiple compressors, and air-cooled equipment are integrated into the main frame to form an independent integrated outdoor unit. Evaporators are installed inside the workshop as needed, which greatly reduces exposed pipes, beautifies the workshop environment, and saves installation space.

[0017] 2. Easy to maintain and upgrade: The modular design of the integrated outdoor unit allows for centralized layout of components, eliminating the need for scattered inspections during maintenance; and the number of compressors can be increased or decreased or components can be replaced according to cooling needs, enabling flexible upgrades.

[0018] 3. Standardized production enables cost reduction: The standardized design of the main frame and internal components facilitates mass production and reduces manufacturing costs; at the same time, it simplifies the installation and commissioning process and improves construction efficiency.

[0025] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0026] Example 1:

[0027] A refrigeration unit based on modular design includes a finned evaporator 11 installed inside the workshop and an integrated outdoor unit placed outside the workshop.

[0028] The main frame of the integrated outdoor unit is made of 304 stainless steel. The bottom frame 10, side plate 1, and top plate are fixed together by bolts. The air intake grille on the surface of the side plate 1 has a louvered structure, which facilitates air intake and prevents dust.

[0029] The condenser 8 and the air-cooled device 2 are fixed to the left and right ends of the bottom frame 10, respectively, within the main frame. The air-cooled device 2 includes three fans connected in parallel. Three scroll compressors 7 are installed in the space between the condenser 8 and the air-cooled device 2, and the compressors 7 are fixed to the bottom frame 10 by bolts.

[0030] A horizontal copper main pipeline (65mm in diameter) is welded to the upper surface of the bottom frame 10. The main pipeline has three connection ports with sealed joints. The connection ports are connected to the air inlet of the compressor 7 through flanges. A gas-liquid separator 9 is connected in series between the refrigerant inlet pipe 6 and the main pipeline.

[0031] The right side of the integrated outdoor unit is equipped with a refrigerant outlet pipe 5, a refrigerant inlet pipe 6, a hot water pipe 4, and a cold water pipe 3. One end of the refrigerant outlet pipe 5 is welded to the condenser 8 and the electronic expansion valve 12, and the other end is connected to the input end of the evaporator 11. One end of the refrigerant inlet pipe 6 is welded to the input end of the gas-liquid separator 9, and the other end is connected to the output end of the evaporator 11. The hot water pipe 4 connects to the hot water outlet of the condenser 8 to transfer waste heat to the workshop hot water tank. The cold water pipe 3 connects to the cooling water interface of the condenser 8, allowing cooling water to be introduced to assist in heat dissipation during high summer temperatures.

[0032] like Figure 5 The refrigeration process is shown in the flowchart below, and the working process is as follows:

[0033] Evaporator 11 absorbs heat from the workshop, causing the internal refrigerant to evaporate into a gaseous state. The gaseous refrigerant enters the main pipeline via refrigerant inlet pipe 6, which distributes the refrigerant to each compressor 7. Compressor 7 compresses the refrigerant into a high-temperature, high-pressure gaseous state and sends it to condenser 8. Condenser 8 dissipates heat through air-cooled equipment 2 and chilled water pipe 3, causing the refrigerant to condense into a high-pressure liquid state. Simultaneously, hot water pipe 4 recovers the waste heat generated during the heat dissipation process. The liquid refrigerant enters evaporator 11 after being throttled and depressurized by electronic expansion valve 12 and refrigerant outlet pipe 5, completing the refrigeration cycle. Furthermore, the number of compressors 7 and the corresponding evaporators 11 can be increased or decreased according to the workshop's usage, thereby meeting the refrigeration needs of workshops of different sizes.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
