Description

Technical Field

[0001] This utility model relates to the field of air conditioning unit technology, specifically to an improvement in the structure of a direct-cooling air conditioning unit. Background Technology

[0002] Outdoor energy storage cabinets suffer from poor heat dissipation due to the large number of batteries installed and solar radiation. High temperatures can reduce battery life, prevent normal charging, and even cause explosions; low winter temperatures can lead to severe battery drain, inability to charge and discharge properly, and reduced lifespan.

[0003] To regulate the temperature of batteries in the energy storage cabinet, a temperature control system is usually configured. Common types of temperature control systems include direct cooling, air cooling, and liquid cooling.

[0004] The direct cooling type is mainly achieved by setting up a direct cooling air conditioning unit. The direct cooling air conditioning unit circulates the refrigerant directly to the direct cooling plate that is in contact with the battery through the circulation pipe. The direct cooling plate is in close contact with the battery and absorbs the heat generated by the battery during charging and discharging more directly, resulting in higher heat exchange efficiency.

[0005] The existing direct-cooling air conditioning unit structure includes: a casing and refrigeration system components, heat exchange module components, electrical control box components, and fan modules arranged inside the casing. The electrical control box components are fixedly assembled inside the casing. If it is necessary to disassemble the electrical control box components for maintenance, the unit must be treated to recover refrigerant, and then the refrigerant pipes connected to the direct cooling plate of the energy storage cabinet must be disconnected. The entire direct-cooling unit must be removed from the energy storage cabinet, and finally the casing must be disassembled for maintenance of the electrical control box components. The entire maintenance process is complicated, time-consuming, and inconvenient. Utility Model Content

[0006] In response to the problems pointed out in the background art, this utility model proposes a direct-cooling air conditioning unit, in which the electrical control box module is removably arranged on the casing, which can be easily disassembled and maintained.

[0007] In some embodiments of this application, an air conditioning unit is proposed, comprising:

[0008] The casing has an opening formed thereon;

[0009] The refrigeration system components are housed within the casing.

[0010] A heat exchange module, connected to the refrigeration system components, is disposed inside the housing and is used to exchange heat with the airflow flowing into the housing.

[0011] A fan module, disposed inside the housing, is used to draw in airflow, allowing it to flow through at least the heat exchange module and the refrigeration system components before being discharged.

[0012] The electrical control box module is arranged side by side with the refrigeration system components and is removable inside the housing, having a first state and a second state;

[0013] When the electronic control box module is in the first state, it is housed inside the casing.

[0014] When in the second state, it is at least partially dislodged from the housing through the opening.

[0015] The above embodiments have the following advantages and effects:

[0016] In this embodiment of the direct-cooling air conditioning unit, the electrical control box module is removably mounted on the casing, and an opening is provided on the casing at a corresponding position. When the electrical control box module needs to be disassembled for maintenance, it can be pulled out from the opening by pulling it relative to the casing, without having to disassemble the surrounding components and the refrigerant piping of the entire unit, making installation and maintenance operations more convenient.

[0017] When the electrical control box module does not require maintenance, it can be pulled to switch to the first state, so that the electrical control box module is built into the housing and the opening is sealed at the same time, thus ensuring the consistency and overall aesthetics of the entire unit.

[0018] In some embodiments of this application, the housing has a first panel portion located on one side of the opening;

[0019] The electrical control box module includes:

[0020] The main body of the electrical control box;

[0021] And the second panel is fixed to the main body of the electrical control box;

[0022] When the electrical control box module is in the first state, the second panel and the first panel are flush.

[0023] When the electrical control box module is in the second state, the second panel and the first panel are separated.

[0024] The above embodiments have the following advantages and effects:

[0025] The electrical control box module is configured as an electrical control box body and a second panel. When disassembly is required, the electrical control box body can be pulled out by applying force to the second panel, which facilitates the pulling out of the electrical control box body.

[0026] Meanwhile, the part that constitutes the panel component is set on the electrical control box module, making the entire panel component a split structure. When the electrical control box module needs to be disassembled for maintenance, it is only necessary to slide the electrical control box module and the second panel part out relative to the housing, without having to disassemble the first panel part, which simplifies the maintenance operation steps and improves the convenience of maintaining the electrical control box module.

[0027] In some embodiments of this application, a guide rail component is provided on the electrical control box module, which includes a guide rail forming part formed by bending, and a support slide is provided on the housing, the support slide being disposed between the electrical control box body and the guide rail forming part.

[0028] The above embodiments have the following advantages and effects:

[0029] By cooperating with the support slide and guide rail forming part on the housing, not only is the sliding of the electrical control box module relative to the housing realized, but also the support of the electrical control box module is realized, ensuring that the electrical control box module can slide smoothly and steadily into and out of the housing.

[0030] In some embodiments of this application, a limiting component is formed on the housing, and a limiting fitting component that cooperates with the limiting component is provided on the electronic control box module;

[0031] When the control box module is in the first state, the limiting component on the housing cooperates with the limiting mating component on the control box body to limit the control box module.

[0032] The above embodiments have the following advantages and effects:

[0033] By using the limiting fitting parts and limiting components on the main body of the control box, the control box module can be fixed in place, thus preventing the control box body from shaking inside the casing.

[0034] Meanwhile, the limiting components set inside the housing can also be used to push the control box module against the column when it is slid into place, allowing the control box module to be quickly pushed into place.

[0035] In some embodiments of this application, the electrical control box module includes:

[0036] The reactor unit, assembled at the end of the electrical control box body opposite to the second panel, includes:

[0037] The reactor protection component is fixed to the outside of the electrical control box body and forms a protective space with the electrical control box body;

[0038] The reactor is assembled within the protected space.

[0039] The above embodiments have the following advantages and effects:

[0040] By installing the reactor separately at the rear of the electrical control box, the high heat generated by the reactor can be effectively prevented from affecting other components inside the box. The reactor is also protected by an external reactor protective cover.

[0041] In some embodiments of this application, the first panel portion is provided with: a first operation portion;

[0042] The refrigerant inlet / outlet valve assembly is connected to the refrigerant inlet / outlet in the refrigerant piping of the refrigeration system components;

[0043] The first wind section is set up through the first panel section.

[0044] In some embodiments of this application, the electrical control box body is provided with:

[0045] The circuit breaker control cover is detachably connected to the main body of the electrical control box;

[0046] The interface section connects to the electrical control components inside the electrical control box body;

[0047] The second panel is provided with:

[0048] The second operating section is used to pull out the electronic control box module; and

[0049] The second return air section is arranged on one side of the interface section, close to the first return air section;

[0050] A clearance section is arranged between the second operating section and the second return air section to avoid the circuit breaker operating cover and the interface section.

[0051] The above embodiments have the following advantages and effects:

[0052] By providing a notch on the second panel and an interface and circuit breaker operation cover on the electrical control box module at the corresponding notch, the circuit breaker component and interface can be easily operated.

[0053] The electrical control box module can be easily pulled out for maintenance via the second operating section on the second panel.

[0054] By increasing the area of ​​the return air section on the second panel, the overall return air volume of the unit is improved.

[0055] In some embodiments of this application, the end face area of ​​the second panel is larger than the end face area of ​​the electrical control box module connected to it. The second panel extends from the electrical control box body to the first panel, and a wiring space is formed on the side of the electrical control box body close to the first panel.

[0056] The above embodiments have the following advantages and effects:

[0057] There are a large number of connecting wires connected to the upper side of the electrical control box body. The wiring space set on the side of the electrical control box body can be used to accommodate a large number of connecting wires, so as to avoid interference from the connecting wires on the side of the electrical control box module when the electrical control box module is pulled out.

[0058] In some embodiments of this application, the housing has a first assembly area and a second assembly area arranged along the length of the housing, and an electronic control component is disposed in the second assembly area.

[0059] A partition is provided in the first assembly area to divide the first assembly area into a first space, and a main control board is provided in the first space;

[0060] The second space is connected to the external space through a connecting part. A drive board is installed in the second space, and a heat dissipation component is installed on the outside of the housing corresponding to the connecting part.

[0061] The above embodiments have the following advantages and effects:

[0062] When arranging the internal structure of the electrical control box, the internal space of the shell is divided into a first assembly area and a second assembly area along the length of the shell. Electrical control components are set in the second assembly area, and partitions are set in the first assembly area, dividing the first assembly area into two layers. The drive board and the main control board are stacked and arranged separately, which realizes the compact layout of the entire electrical control box structure and reduces the space occupied.

[0063] In some embodiments of this application, the housing includes a first mounting area, a second mounting area, and a third mounting area. The refrigeration system components are arranged in the first mounting area, the electrical control box module is arranged side by side with the refrigeration system components, the heat exchange module is assembled in the second mounting area, and the fan module is assembled in the third mounting area.

[0064] The above embodiments have the following advantages and effects:

[0065] In this embodiment, the direct-cooling air conditioning unit divides the interior of the casing into a first installation area, a second installation area, and a third installation area, thus realizing the partitioned layout of the casing. This allows different functional modules to be installed in different areas, facilitating production wiring, piping and circuit design, and subsequent maintenance.

[0066] Meanwhile, multiple components used for direct cooling were modularly assembled. Before the whole unit was assembled, the heat exchanger, fan and electrical control box were pre-assembled into separate heat exchange modules, fan modules and electrical control box modules. During assembly, each module only needs to be assembled with the casing, without the need for each component to be installed and fixed separately. This not only simplifies the structure of the whole unit, but also makes the assembly of the whole unit simpler and more convenient.

[0093] In some embodiments of this application, an air conditioning unit is proposed, including a casing 100 and a refrigeration system assembly 500, a heat exchange module 300, a fan module 400, and an electrical control box module 200 arranged inside the casing 100.

[0094] The refrigeration system component 500 mainly transmits refrigerant to the direct cooling fins located in the energy storage cabinet through refrigerant pipelines to regulate the temperature of the batteries in the energy storage cabinet.

[0095] The heat exchange module 300 is connected to the refrigeration system component 500 and is disposed inside the housing 100 to exchange heat with the airflow flowing in from the air inlet.

[0096] A return air section and an air outlet section 180 are formed on the housing 100. The return air section is a return air inlet used to introduce airflow into the housing 100, and the air outlet section 180 is an air outlet used to discharge airflow from the housing 100.

[0097] The return air section is the return air inlet, and the air outlet section 180 is the air outlet, arranged opposite to the return air inlet.

[0098] The fan module 400 is installed inside the housing 100 and is used to draw airflow from the return air section, so that it flows through at least the heat exchange module 300 and the refrigeration system components 500 before being sent out from the air outlet 180. The main function of the fan module 400 is to drive the circulation of airflow.

[0099] In some embodiments of this application, an opening 150 is formed on the housing 100.

[0100] The electrical control box module 200 is removably installed inside the housing 100.

[0101] Specifically, the control box module 200 extends out of the opening 150 or slides into the housing 100 through the opening 150, and the opening 150 is the inlet and outlet for the control box module 200 to enter and exit the housing 100.

[0102] The electrical control box module 200 has a first state and a second state;

[0103] When the electrical control box module 200 is in the first state, it is located inside the housing 100 and blocks the opening 150.

[0104] When in the second state, it is at least partially dislodged from the housing 100 through the opening 150.

[0105] The above embodiments have the following advantages and effects:

[0106] In this embodiment, the air conditioning unit has a removable control box module 200 installed inside the housing 100. An opening 150 is provided on the housing 100 at a corresponding position. When the control box module 200 needs to be disassembled for maintenance, it can be pulled out from the opening 150 by pulling it relative to the housing 100. There is no need to disassemble the surrounding components and the refrigerant piping of the entire unit, making installation and maintenance more convenient.

[0107] When the electrical control box module 200 does not require maintenance, it can be pulled to switch to the first state, so that the electrical control box module 200 is built into the housing 100 and the opening 150 is sealed at the same time, thus ensuring the consistency and overall aesthetics of the entire unit.

[0108] In some embodiments of this application, the housing 100 includes: a first housing member 110, including: a bottom wall portion 111 for forming the bottom wall of the housing 100; and

[0109] Two side wall portions 112 are provided and arranged opposite to each other. They are formed by bending from the bottom wall portion 111 and are used to form the side wall of the housing 100.

[0110] The bottom wall part 111 is the bottom plate, and the side arm part is the side plate formed by bending directly from both sides of the bottom plate.

[0111] The above embodiments have the following advantages and effects:

[0112] The bottom wall and two side walls of the housing 100 are directly formed by the first housing component 110 constituting the housing 100, realizing the integrated processing and forming of the bottom plate and the two side plates.

[0113] Furthermore, when assembling the casing 100, only the front panel components, rear panel, and top panel need to be fixed, saving the assembly time and steps of the left and right side panels and improving the convenience of processing and assembly.

[0114] In some embodiments of this application, the housing 100 has a first panel portion 140 located on one side of the opening portion 150.

[0115] A first panel portion 140 is connected to one of the side wall portions 112 and the bottom wall portion 111, and an opening 150 is formed between the first panel portion 140 and the other side wall portion 112 and the bottom wall portion 111.

[0116] The first panel portion 140 is a first panel that constitutes part of the panel component of the housing 100.

[0117] The electrical control box module 200 includes an electrical control box body 210 and a second panel 220, which is fixed to the electrical control box body 210.

[0118] The second panel 220 is a second panel, which, when docked with the first panel 140, forms the panel component of the entire housing 100.

[0119] The second panel 220 is fixed to one end of the electrical control box body 210, and it fits against the end face of the electrical control box body 210 near the return air section and is locked to it by screws.

[0120] When the electrical control box module 200 is in the first state, the second panel 220 blocks the opening 150 and docks with the first panel 140, eventually becoming flush with the first panel 140.

[0121] When the electrical control box is not disassembled for maintenance, the opening 150 is sealed by the second panel 220 and fixed to the first panel 140 to form a complete panel component, ensuring the overall aesthetic appearance of the unit.

[0122] When the electrical control box module 200 is in the second state, the second panel 220 and the first panel 140 are separated.

[0123] During disassembly and maintenance, the second panel 220 is pulled out of the housing 100 along with the electrical control box body 210.

[0124] The first panel 140 is provided with a first flange, and the second panel 220 is provided with a second flange. When they are joined together, the second flange and the first flange are attached and locked together by screws, wherein the second flange is located on the front side of the first flange.

[0125] When maintenance is required, the screws between the two can be removed to unlock the first panel 140 and the second panel 220, and then the electrical control box module 200 can be slid and stretched.

[0126] The above embodiments have the following advantages and effects:

[0127] The electrical control box module 200 is configured as an electrical control box body 210 and a second panel 220. When disassembly is required, the electrical control box body 210 can be pulled out by applying force to the second panel 220, which facilitates the pulling out of the electrical control box body 210.

[0128] Meanwhile, the part constituting the panel component is set on the electrical control box module 200, making the entire panel component a split structure. When the electrical control box module 200 needs to be disassembled for maintenance, it is only necessary to slide the electrical control box module 200 and the second panel part 220 out relative to the housing 100, without having to disassemble the first panel part 140, which simplifies the maintenance operation steps and improves the convenience of maintaining the electrical control box module 200.

During maintenance, the electrical control box module 200 can be pulled to slide between the guide rail forming parts 272 and the electrical control box body 210 through the support slides 160 to achieve the effect of sliding in or out.

[0131] In some embodiments of this application, the electrical control box body 210 includes: a guide rail connecting part 271, and the guide rail connecting part 271 and the electrical control box body 210 are fixed together;

[0132] The guide rail forming part 272 is formed by bending from the guide rail connecting part 271.

[0133] The guide rail connecting part 271 is a guide rail connecting rib plate, which is attached to the bottom of the electrical control box body 210 and extends along the length direction of the electrical control box body 210. When connecting, it is welded and fixed to the bottom of the electrical control box body 210.

[0134] The guide rail forming part 272 is formed by bending downward from the bottom of the control box body 210 relative to the guide rail connecting part 271. It is a guide rail forming rib. After bending, the guide rail forming part 272 has a gap with the bottom of the control box body 210. It and the control box body 210 form a sliding locking groove to facilitate cooperation with the housing 100.

[0135] In some embodiments of this application, the support slide 160 includes:

[0136] Support connection 161; and

[0137] Support part 162 and vertical support connection part 161 are provided;

[0138] A sliding part 163 is connected to the support part 162 and is inserted between the electrical control box body and the guide rail forming part.

[0139] The supporting connection part 161 is a supporting connection plate rib, which fits against the bottom wall of the housing 100 and is welded and fixed to the bottom wall of the housing 100.

[0140] The support part 162 is a support rib, which is formed by bending from the support connection part 161. The vertical support connection part 161 is provided to support the electrical control box body 210.

[0141] The sliding part 163 is formed by bending from the support part 162 and is a sliding rib.

[0142] The Z-shaped support slide is formed by the interconnection of the support connection part 161, the support part 162 and the sliding part 163, which is inserted into the guide rail forming part 272 and the electrical control box body 210.

[0143] The above embodiments have the following advantages and effects:

[0144] The support slide structure is configured as a structure in which the support connection part 161, the support part 162 and the sliding part 163 are interconnected. The support connection part 161 is used to connect and fix it to the housing 100, the support part 162 is used to support the electrical control box body 210, and the sliding part 163 is used to slide and engage with the electrical control box body 210.

[0199] The electrical control box module 200 is assembled in the first installation area 131 and arranged side by side with the refrigeration system component 500 along the vertical return air section to the air outlet section 180.

[0201] The heat exchange module 300 is assembled in the second mounting area 132;

[0202] The fan module 400 is assembled in the third installation area 133.

[0203] The airflow is drawn in through the air inlet by the fan module 400, and then flows through the first installation area 131. When flowing through the first installation area 131, it will simultaneously flow through the electrical control box module 200 and the refrigeration system component 500 to dissipate heat. The airflow flowing through the first installation area 131 enters the second installation area 132 and flows through the heat exchange module 300. Through the heat exchange module 300, the airflow is cooled down or heated up, and then it is sent out from the air outlet 180 by the fan module 400.

[0204] The above embodiments have the following advantages and effects:

[0205] In this embodiment, the direct-cooling air conditioning unit divides the interior of the casing 100 into a first installation area 131, a second installation area 132, and a third installation area 133, thus realizing the partitioned layout of the casing 100. This allows different functional modules to be installed in different areas, facilitating production wiring, pipeline circuit design, and subsequent maintenance.

[0206] Meanwhile, multiple components used for direct cooling were modularly assembled. Before the whole unit was assembled, the heat exchanger 310, the fan 420, and the electrical control box were pre-assembled into separate heat exchange modules 300, fan modules 400, and electrical control box modules 200. During assembly, each module only needs to be assembled with the casing 100, without the need for each component to be installed and fixed separately.

[0221] In some embodiments of this application, the housing 100 includes a second housing member 120 for forming the top wall of the housing 100 and connected to the first housing member 110.

[0222] The second housing component 120 is a top plate, which is connected and fixed to the two side wall portions 112.

[0223] The fan module 400 includes:

[0224] The partition 410 is a partition plate that is vertically arranged inside the housing 100.

[0225] The partition 410 includes: a first connecting portion 411 formed at both ends of the partition 410 and connected to the two side wall portions 112 respectively;

[0226] The second connecting portion 412 is formed at the bottom of the partition member 410 and is connected to the bottom wall portion 111;

[0227] The third connecting part 413 is formed on the top of the partition 410 and is connected to the second housing member 120.

[0232] The fan assembly is mounted on the partition 410.

[0233] During assembly, the fan components are first installed onto the partition 410, and then the entire fan module 400 is assembled onto the first housing component 110 and the second housing component 120 through the first connecting part 411, the second connecting part 412 and the third connecting part 413 on the partition 410, so as to achieve rapid installation.

[0234] In some embodiments of this application, the fan assembly includes at least one fan 420, a fan bracket 430 for mounting the fan 420, a baffle plate 440 arranged between adjacent fans 420, and a guide ring 450 for guiding airflow to the fan 420.

[0235] The wind deflector 440, the air guide ring 450, and the fan bracket 430 are all fixedly connected to the partition 410 by screws.

[0236] The above embodiments have the following advantages and effects:

[0237] The fan module 400 is configured as a partition 410 and a fan assembly structure. During assembly, the fan 420, which constitutes the fan assembly, can be installed on the fan 420 bracket. Then, the fan 420 bracket, the baffle plate 440, and the air guide ring 450 are all fixed to the partition 410, realizing the modular assembly of the fan 420 part and facilitating the overall installation and assembly.

[0238] In some embodiments of this application, the refrigeration system component 500 includes a compressor 510, a heat exchanger 310, a liquid receiver 530, an economizer 540, a refrigerant heater 550, and a valve assembly interconnected by refrigerant pipelines. The valve assembly includes a four-way valve 560, an electronic expansion valve 570, a shut-off valve, and a three-way valve 590.

[0239] Specifically, the compressor 510, four-way valve 560, heat exchanger 310, economizer 540, and direct cooling plate located in the energy storage cabinet are connected by refrigerant pipelines to form a refrigerant circulation loop.

[0240] The shut-off valve includes a first shut-off valve and a second shut-off valve, which together form the refrigerant inlet / outlet valve assembly 143. The first shut-off valve is arranged between the electronic expansion valve 570 and the direct cooling plate.

[0241] The refrigerant heater 550 is connected to the pipeline between the compressor 510 and the direct cooling plate;

[0242] By adding a refrigerant heater 550 to the refrigerant circulation loop, the heating capacity in low-temperature environments is improved, solving the problem of insufficient heating capacity of existing energy storage cabinets in low-temperature environments.

[0243] The electronic expansion valve 570 is connected between the economizer 540 and the direct cooling plate and is used to expand the condensed high-temperature and high-pressure liquid refrigerant into a low-pressure liquid refrigerant.

[0244] The economizer 540 has a first passage that connects the heat exchanger 310 and the direct cooling plate.

[0245] The economizer 540 has a second passage defined within it, and the first passage and the second passage are not connected to each other. One end of the second passage is connected to the end of the direct cooling plate away from the heat exchanger 310, and both ends of the second passage are connected to the compressor 510 through a three-way valve 590.

[0246] The function of the economizer 540 is to absorb heat through the throttling and evaporation of the refrigerant, thereby subcooling another part of the refrigerant. The economizer 540 can provide additional subcooling for the refrigerant and can also limit the superheat of the refrigerant vapor coming out of the direct cooling plate.

[0247] The liquid receiver is connected between the heat exchanger 310 and the economizer 540.

[0248] The direct cooling system components also include an oil separator connected to the discharge pipe of the compressor 510. The oil separator can separate the lubricating oil in the refrigerant and return it to the compressor 510 to ensure that the compressor 510 has enough lubricating oil for lubrication and cooling, and to prevent the compressor 510 from being damaged due to lack of oil.

[0249] The direct cooling system components also include a gas-liquid separator, which is connected to the suction line of the compressor 510. It can separate the liquid part of the refrigerant and only allow the gaseous refrigerant to enter the compressor 510, thereby effectively preventing liquid slugging.

[0250] During refrigeration, the refrigerant is compressed into a high-temperature, high-pressure gas by the compressor 510. The exhaust gas from the compressor 510 passes through an oil separator for oil-gas separation. The gaseous refrigerant enters the heat exchanger 310 for heat exchange and condensation. The separated oil from the compressor 510 returns to the compressor 510's suction line through the oil return system. The condensed refrigerant is then subcooled by the economizer 540 to increase the subcooling degree and improve the refrigeration effect.

[0251] The subcooled refrigerant is throttled by the electronic expansion valve 570 and enters each direct cooling plate through the first shut-off valve. The refrigerant evaporates and absorbs heat in the direct cooling plate to cool the battery.

[0252] After evaporation, the refrigerant flow rate into the economizer 540 is regulated by the three-way valve 590. The gas-liquid separator separates the return gas from the compressor 510 to prevent liquid from being drawn into the compressor 510.

[0253] During heating, the refrigerant is compressed into a high-temperature, high-pressure gas by compressor 510. The exhaust gas from compressor 510 passes through an oil separator for oil-gas separation. The separated oil from compressor 510 enters the suction line of compressor 510 through the oil return system. Switched by four-way valve 560, the refrigerant discharged from compressor 510 first passes through economizer 540 for condensation, then passes through the second shut-off valve before entering each direct cooling plate to ensure uniform flow. It continues to condense and release heat on the direct cooling plates, heating the battery.

[0254] The flow rate into the economizer 540 is regulated by a three-way valve 590 to ensure that the temperature of the refrigerant entering the direct cooling plate is within a suitable range. After condensation, the refrigerant passes through the first shut-off valve, then through the electronic expansion valve 570 for throttling, and then through the economizer 540 and heat exchanger 310 for evaporation before returning to the suction line of the compressor 510 to complete the heating cycle.

[0255] When heating at low temperatures, the refrigerant heater 550 is turned on to heat the refrigerant. The refrigerant is compressed into a high-temperature and high-pressure gas by the compressor 510. The exhaust gas from the compressor 510 enters the direct cooling plate, where it undergoes condensation and heat exchange. At this time, the electronic expansion valve 570 is fully open, and the gas returns to the intake after passing through the economizer 540 and the heat exchanger 310, completing the low-temperature heating cycle.

[0256] In some embodiments of this application, the compressor 510, refrigerant heater 550 and three-way valve 590 are collinear and close to the return air section, and the liquid storage tank 530, economizer 540, four-way valve 560, electronic expansion valve 570 and shut-off valve are collinear and close to the air outlet section 180.

[0257] The above embodiments have the following advantages and effects:

[0258] The compressor 510, condenser heater, and three-way valve 590 are arranged collinearly in the first mounting area 131. The liquid receiver 530, economizer 540, four-way valve 560, electronic expansion valve 570, and shut-off valve are also arranged collinearly in the first mounting area 131. During assembly, each component can be assembled onto the base in a straight line before the copper pipes are welded together. This facilitates installation and pipe assembly welding, and improves the installation and assembly efficiency of the refrigeration system components 500.

[0259] In some embodiments of this application, drainage sections are provided in the first mounting area 131, the second mounting area 132, and the third mounting area 133. The drainage sections are drainage holes formed on the bottom walls of the first mounting area 131, the second mounting area 132, and the third mounting area 133. The drainage sections facilitate the drainage of condensate and external water in each area, preventing water accumulation in the mounting areas.
