[0048] Figure 1 shows a schematic diagram of a wind wall device provided by an embodiment of the present application. The wind wall device 1 includes a cooling water coil 11, a condenser 12, a compressor 13, an evaporator 14, a fan 15, a pipe inlet 16, and a pipe outlet 17.

[0049] The wind wall device 1 is used to reduce the temperature of the heat source device 4 through air cooling. Specifically, the fan 15 in the wind wall device 1 is used to reduce the temperature of the heat source device 4 through air cooling based on the air cooled by the cooling water coil 11 and / or the evaporator 14. In one example, the fan 15 pumps cold air toward the heat source device 4. The cold air is the result of ambient air being cooled by the fan 15 as it passes through the cooling water coil 11 and / or the evaporator 14.

[0050] For example, the heat source device 4 can be a server or server cluster in a computer room, or a terminal that generates heat due to operation. In some examples, the heat source device can also be implemented as equipment that generates heat during industrial production, such as machine tools, power generation equipment, etc. Any device with heat dissipation requirements can be called a heat source device, and this application does not limit the type of heat source device.

[0051] Furthermore, the wind wall device 1 also includes a filter 18, which is used to filter dust from the ambient air to prevent dust and other particles from entering the wind wall device 1. In one example, when the ambient air is subjected to the force of the fan 15, it is first filtered by the filter 18 before entering the wind wall device 1 and then cooled by the cooling water coil 11 and / or the evaporator 14. A first solid arrow 301 shows the direction in which ambient air flows into the wind wall device 1, and a second solid arrow 302 shows the direction in which the cooled air flows out of the wind wall device 1.

[0052] The condenser 12 , the compressor 13 , and the evaporator 14 in the wind wall device 1 are connected in pairs in sequence.

[0053] The compressor 13 is used to pressurize the fluid flowing out of the evaporator 14; the evaporator 14 is used to convert the liquid flowing out of the condenser 12 into a gas state, and evaporates and absorbs heat during the process of converting the liquid into a gas state to achieve cooling of the air outside the evaporator 14.

[0054] The fluids in the first branch and the second branch inside the condenser exchange heat, and the two sides of the second branch are respectively connected to the compressor 13 and the evaporator 14. The two sides of the first branch are respectively connected to the pipeline inlet 16 and the pipeline outlet 17.

[0055] Both sides of the cooling water coil 11 are connected to the pipeline inlet 16 and the pipeline outlet 17 respectively. The fluid in the cooling water coil 11 absorbs the heat of the air outside the cooling water coil 11 to cool the air outside the cooling water coil 11.

[0056] In one example, the wind wall device 1 is connected to the cooling tower 3; specifically, the pipe inlet 16 is connected to the output end of the cooling tower 3, and the pipe outlet 17 is connected to the input end of the cooling tower 3. The cooling tower 3 is a thermal device used to cool the incoming fluid and discharge the cooled fluid.

[0057] The cooling water coil 11, condenser 12, compressor 13, evaporator 14, fan 15, pipe inlet 16, and pipe outlet 17 in the wind wall device 1 can be collectively referred to as hardware components. The connection relationship between the various hardware components of the wind wall device 1 in FIG. 1 will be described separately below as an example, and the connection relationship between the wind wall device 1 and the cooling tower 3 will also be described separately below as an example; these connections are not shown in FIG. 1 .

[0058] FIG2 shows a structural block diagram of a wind wall device provided in one embodiment of the present application.

[0059] The wind wall device 1 includes a cooling water coil 11, a condenser 12, a compressor 13, an evaporator 14, a fan 15, a pipeline inlet 16, a pipeline outlet 17, and a first pipeline section 21, a second pipeline section 22, a third pipeline section 23, a fourth pipeline section 24, a fifth pipeline section 25, and a sixth pipeline section 26. In the various structural block diagrams of this application, the solid triangular arrows drawn on the pipeline sections are only used to exemplify the flow direction of the fluid in the pipeline sections and do not limit the pipeline sections in any way.

[0060] The first pipe portion 21 is used to connect the pipe inlet 16 and the first end of the cooling water coil 11;

[0061] The fluid in the cooling water coil 11 absorbs heat from the air outside the cooling water coil 11 to cool the air outside the cooling water coil 11. This embodiment does not impose any restrictions on parameters such as the material, bending method, length, and diameter of the cooling water coil 11.

[0062] Exemplarily, the first end of the cooling water coil 11 is the input end of the cooling water coil 11 , and correspondingly, the second end of the cooling water coil 11 is the output end of the cooling water coil 11 .

[0063] The second end of the cooling water coil 11 is connected to the pipe outlet 17. In one example, the second end of the cooling water coil 11 and the pipe outlet 17 can be directly connected via a pipe section. For example, as shown in FIG2 , the wind wall device 1 further includes a ninth pipe section 29; the ninth pipe section 29 is used to connect the second end of the cooling water coil 11 and the pipe outlet 17. In another example, the second end of the cooling water coil 11 and the pipe outlet 17 can also be connected via multiple pipe sections and at least one hardware component (such as the condenser 12, etc.), which will be separately explained below through an embodiment.

[0064] It can be seen that the present application does not limit the communication method between the second end of the cooling water coil 11 and the pipe outlet 17. The ninth pipe portion 29 shown in Figure 2 is only one implementation method of the communication between the second end of the cooling water coil 11 and the pipe outlet 17.

[0065] A second pipe portion 22 is used to connect the pipe inlet 16 and the first input end of the condenser 12;

[0066] The third pipe portion 23 is used to connect the first output end of the condenser 12 with the pipe outlet 17;

[0067] The condenser 12 includes a first input end, a first output end, a second input end, and a second output end; the pipeline between the first input end and the first output end inside the condenser 12 is a first branch 121, and the pipeline between the second input end and the second output end inside the condenser 12 is a second branch 122.

[0068] The first branch 121 and the second branch 122 inside the condenser 12 are two independent branches. The fluids carried in the two branches are independent of each other and will not mix. The fluids in the first branch 121 and the second branch 122 inside the condenser 12 exchange heat.

[0069] In one example, the temperature of the fluid in the first branch 121 is lower than the temperature of the fluid in the second branch 122, and the fluid in the first branch 121 cools the fluid in the second branch 122. Furthermore, the fluid in the first branch 121 is a liquid (such as water), and the fluid in the second branch 122 is a liquid or a gas (such as a liquid or gaseous refrigerant, liquid water, or water vapor).

[0070] The fourth pipe section 24 is used to connect the output end of the evaporator 14 and the input end of the compressor 13;

[0071] The fifth piping section 25 is used to connect the output end of the compressor 13 and the second input end of the condenser 12; illustratively, in FIG2 , the first input end and the second input end of the condenser 12 are arranged on both sides of the condenser 12; it is understandable that in different implementations, the two input ends of the condenser 12 can also be arranged on the same side. Similarly, the two output ends of the condenser 12 can be arranged on the same side or on both sides. Exemplarily, the same side position is used to indicate that they are arranged on the same outer surface of the condenser. It can be seen that this embodiment does not limit the position at which the input end and the output end of the condenser 12 are arranged, and the position of the input end and the output end on the condenser 12 can be adjusted to ensure the convenience of connection between the condenser and the piping section or other hardware components.

[0072] A sixth pipe portion 26 is used to connect the second output end of the condenser 12 and the input end of the evaporator 14;

[0073] Compressor 13 is used to pressurize the fluid flowing out of evaporator 14 to produce a high-pressure fluid. As described above, the high-pressure fluid produced by compressor 13 can be, for example, a liquid or a gas. Evaporator 14 is used to convert the liquid flowing out of the second output port of condenser 12 into a gaseous state. During this conversion, the liquid evaporates and absorbs heat, thereby cooling the air outside evaporator 14.

[0074] The fan 15 in the wind wall device 1 is used to reduce the temperature of the heat source device in an air-cooling manner based on the air cooled by the cooling water coil 11 and / or the evaporator 14 .

[0075] It should be noted that in the various structural block diagrams of the present application, the pipeline portion can be implemented as a fluid pipeline to connect two hardware components. In one example, the fluid pipeline is an air-tight or liquid-tight pipeline to avoid leakage of the fluid carried in the fluid pipeline; the present application does not limit the material, length, and connection method between the pipeline portion and the hardware component, nor does it exclude the situation where the pipeline portion can be implemented as other physical devices other than the fluid pipeline. In the various structural block diagrams of the present application, the solid triangular arrow drawn on the pipeline portion is only used to exemplarily show the flow direction of the fluid in the pipeline portion, and does not impose any limitation on the pipeline portion.

[0076] In summary, the method provided in this embodiment provides multiple ways to cool the air through the cooling water coil and the evaporator, expanding the way to obtain cooled cold air when lowering the temperature of the heat source equipment by air cooling; through the condenser, it can achieve the cooling of the fluid output by the compressor based on the fluid flowing into the pipeline inlet, creating favorable evaporation conditions for the evaporator to cool the ambient air; and improves the efficiency of lowering the temperature of the heat source equipment by air cooling based on the wind wall device.

[0077] FIG3 shows a structural block diagram of a wind wall device provided in one embodiment of the present application.

[0078] Wind wall equipment 1 includes a cooling water coil 11, a condenser 12, a compressor 13, an evaporator 14, a fan 15, a pipe inlet 16, a pipe outlet 17, and a first pipe section 21, a second pipe section 22, a third pipe section 23, a fourth pipe section 24, a fifth pipe section 25, and a sixth pipe section 26. Wind wall equipment 1 also includes a seventh pipe section 27.

[0079] In the embodiment shown in FIG3 , for descriptions of the cooling water coil 11 to the pipe outlet 17 and the first pipe section 21 to the sixth pipe section 26 , please refer to the descriptions in the embodiment corresponding to FIG2 above, which will not be repeated here.

[0080] A seventh pipe section 27 is used to connect the second end of the cooling water coil 11 and the first input end of the condenser 12;

[0081] In the embodiment, the second end of the cooling water coil 11 passes through the seventh pipe portion 27 , the first branch in the condenser 12 , and the third pipe portion, and is communicated with the pipe outlet.

[0082] That is, the second end of the cooling water coil 11 and the pipe outlet 17 in this embodiment are connected to at least one hardware component (such as the condenser 12) through multiple pipe sections (such as the seventh pipe section 27 and the third pipe section 23).

[0083] In summary, the method provided in this embodiment provides a seventh pipeline section, enriching the connection method between the second end of the cooling water coil and the pipeline outlet; provides a variety of ways to cool the air through the cooling water coil and the evaporator, and expands the method of obtaining cooled cold air when the temperature of the heat source equipment is lowered by air cooling; through the condenser, it can be achieved based on the fluid flowing into the pipeline inlet, the fluid output by the compressor is cooled, and favorable evaporation conditions are created for the evaporator to cool the ambient air; and the efficiency of lowering the temperature of the heat source equipment by air cooling based on the wind wall device is improved.

[0084] FIG4 shows a flow chart of a method for controlling a wind wall device provided by an exemplary embodiment of the present application. The method can be executed by a computer device. The computer device refers to an electronic device with data calculation, processing and storage capabilities. The method for controlling a wind wall device can be executed by a terminal (such as a client of a target application installed and running in a terminal executing the method for controlling a wind wall device), or by a server, or by a terminal and a server interacting and cooperating to execute the method, which is not limited by the present application.

[0085] The terminal may be an electronic device such as a mobile phone, a tablet computer, a vehicle-mounted terminal (vehicle computer), a wearable device, a PC (Personal Computer), an access control device, an unmanned vending terminal, etc. The terminal may be installed with a client that runs a target application. The target application may be a control application for a wind wall device, or other application that provides the control function of a wind wall device. This application does not limit this. In addition, this application does not limit the form of the target application, including but not limited to an App (Application) installed in the terminal, a mini-program, etc., and may also be in the form of a web page.

[0086] The server can be a standalone physical server, a server cluster or distributed system consisting of multiple physical servers, or a cloud server providing cloud computing services. The server can be the backend server of the target application, used to provide backend services to the client of the target application.

[0087] The method is applied to a wind wall device. FIG5 shows a structural block diagram of a wind wall device provided by an embodiment of the present application. That is, based on the embodiment shown in FIG3 , the wind wall device 1 further includes: a first three-way valve 275 .

[0088] The second pipeline portion 22 is used to connect the pipeline inlet 16 with the first input end of the first three-way valve 275, and to connect the output end of the first three-way valve 275 with the first input end of the condenser 12;

[0089] The seventh pipe section 27 is used to connect the second end of the cooling water coil 11 with the second input end of the first three-way valve 275 , and to connect the output end of the first three-way valve 275 with the first input end of the condenser 12 .

[0090] In the embodiment shown in FIG5 , for details not yet described about the cooling water coil 11 to the pipe outlet 17 and the first pipe section 21 to the sixth pipe section 26 , please refer to the description in the embodiment corresponding to FIG2 above, which will not be repeated here.

[0091] The control method of the wind wall device includes:

[0092] Step 510: Control the fan to be in an activated state, and reduce the temperature of the heat source device by air cooling based on the air cooled by the cooling water coil and / or the evaporator;

[0093] When the fan is in the started state, the fan draws air from the first side to the second side, thereby reducing the temperature of the heat source equipment in an air-cooling manner on the second side of the fan.

[0094] The air is drawn from the first side of the fan to the second side by the fan under the force of the fan, and then blown to the heat source equipment; on either side of the fan, the air is cooled by the cooling water coil and / or evaporator, thereby reducing the temperature of the heat source equipment by air cooling.

[0095] It should be noted that the air is cooled by the cooling water coil and / or evaporator on either side of the fan. Steps 530 to 550 below will respectively introduce the air cooling method of the pipe diameter by one or more hardware components.

[0096] It should be noted that, in this embodiment, step 510 may be performed before, after, or simultaneously with any step in the first step group, which includes steps 520 to 550. This embodiment does not impose any restrictive provisions on the execution.

[0097] It should be noted that step 510 in this embodiment can be implemented independently to form a new embodiment. For example, when step 510 is implemented independently, the control method of the wind wall device can be applied to the wind wall device shown in any of Figures 2, 3, and 5 above, or any wind wall device shown in this application, and this application does not impose any restrictive provisions on this.

[0098] Step 520: Obtain a first temperature at the location of the cooling tower;

[0099] The pipeline inlet is connected to the output end of the cooling tower, and the pipeline outlet is connected to the input end of the cooling tower. The cooling tower is a thermal device that cools the incoming fluid and discharges the cooled fluid. In one example, the cooling tower can be implemented as a closed cooling tower.

[0100] For example, the first temperature may be the ambient temperature at the location of the cooling tower, or the temperature of the fluid at or near the output end of the cooling tower. For example, the first temperature may be a temperature measured using a dry-bulb method or a temperature measured using a wet-bulb method.

[0101] Step 530: When the first temperature exceeds the first threshold, the second input end of the first three-way valve is controlled to be closed, so that the fluid flowing out of the pipeline inlet is guided to sequentially pass through the second pipeline portion, the first input end and the output end of the first three-way valve, and flow out to the first input end of the condenser; and the compressor is controlled to be in an activated state to pressurize the fluid flowing out of the evaporator to obtain high-pressure fluid.

[0102] When the first temperature exceeds the first threshold, the temperature of the environment where the cooling tower is located is relatively high, and the fluid flowing out of the output end of the cooling tower is unable to cool the ambient air even if it flows to the cooling water coil.

[0103] By controlling the second input end of the first three-way valve to be closed (in the embodiment corresponding to FIG5 , this is also referred to as controlling the first three-way valve to be in a full bypass state), the fluid flowing out of the pipeline inlet is prevented from continuously flowing through the cooling water coil.

[0104] The compressor is controlled to be in the starting state, and the fluid flowing out of the evaporator is pressurized to obtain high-pressure fluid; when the second input end of the first three-way valve is closed, the entire amount of fluid flowing out of the pipeline inlet is guided to the first input end that directly flows into the condenser, and the fluid flowing out of the pipeline inlet cools the fluid in the second branch in the first branch inside the condenser.

[0105] In this step, since the fluid flowing to the cooling water coil does not have the ability to cool the ambient air and the compressor is in the starting state, the fan accordingly lowers the temperature of the heat source equipment in an air-cooling manner based on the air cooled by the evaporator.

[0106] Step 540: When the first temperature does not exceed the first threshold value and exceeds the second threshold value, the first input end of the first three-way valve is controlled to be closed, thereby directing the fluid flowing out of the pipeline inlet to sequentially pass through the first pipeline portion, the cooling water coil, and the seventh pipeline portion, and then flow out to the first input end of the condenser; and the compressor is controlled to be in an activated state to pressurize the fluid flowing out of the evaporator to obtain high-pressure fluid.

[0107] When the first temperature does not exceed the first threshold and exceeds the second threshold, the temperature of the environment in which the cooling tower is located is moderate, and the fluid flowing out of the output end of the cooling tower is capable of cooling the ambient air when flowing to the cooling water coil. For example, in this embodiment, the first threshold is greater than the second threshold.

[0108] By controlling the first input end of the first three-way valve to be closed (in the embodiment corresponding to FIG5 , this is also referred to as controlling the first three-way valve to be in the full main state), the fluid flowing out of the pipeline inlet continuously flows through the cooling water coil.

[0109] The compressor is controlled to be in the starting state, and the fluid flowing out of the evaporator is pressurized to obtain high-pressure fluid; when the first input end of the first three-way valve is closed, the fluid flowing out of the pipeline inlet is first fully guided to the cooling water coil to cool the ambient air; and then fully guided to the first input end flowing into the condenser, and the fluid in the second branch is cooled in the first branch inside the condenser.

[0110] In this step, since the fluid flowing to the cooling water coil has the ability to cool the ambient air and the compressor is in the started state, the fan accordingly lowers the temperature of the heat source equipment by air cooling based on the air cooled by the cooling water coil and the evaporator.

[0111] Step 550: When the first temperature does not exceed the second threshold, control the opening and closing ratio between the first input end and the second input end of the first three-way valve according to the first temperature; and control the compressor to be in a stopped state;

[0112] If the first temperature does not exceed the second threshold, the ambient temperature of the cooling tower is relatively low, and the ambient air cooling requirement can be met solely by the cooling capacity of the fluid flowing out of the cooling tower's output end and into the cooling water coil. This means that the ambient air cooling requirement can be met without starting the compressor.

[0113] According to the first temperature, the opening and closing ratio between the first input end and the second input end of the first three-way valve is controlled (in the embodiment corresponding to Figure 5, this is also called controlling the first three-way valve to be in an adjustment state), so that part of the fluid flowing out of the pipeline inlet continues to flow through the cooling water coil.

[0114] As the first temperature decreases, the ability of the fluid flowing out of the output end of the cooling tower to cool the ambient air increases when it flows into the cooling water coil. By controlling the opening and closing ratio between the first input end and the second input end of the first three-way valve to increase, the flow rate of the fluid continuously flowing through the cooling water coil is reduced, so as to achieve a fixed ability to cool the ambient air in the cooling water coil.

[0115] Similarly, as the first temperature increases, the opening and closing ratio between the first input end and the second input end is reduced to achieve a constant cooling capacity of the cooling water coil for the ambient air.

[0116] It can be seen from the above that the opening and closing ratio between the first input end and the second input end of the first three-way valve is inversely correlated with the first temperature.

[0117] In this step, since the fluid flowing to the cooling water coil has the ability to cool the ambient air and the compressor is in a stopped state, the fan accordingly lowers the temperature of the heat source equipment in an air-cooling manner based on the air cooled by the cooling water coil.

[0118] It should be noted that any of step 530, step 540 and step 550 in this embodiment can be combined with step 510 and step 520 to form a new embodiment and implemented separately, and this application does not make any restrictive provisions on this.

[0119] In summary, the method provided in this embodiment provides a seventh pipeline portion and a first three-way valve, enriching the connection mode between the second end of the cooling water coil and the pipeline outlet; providing an opening and closing mode of the first three-way valve at different temperatures; providing a variety of ways to cool the air through the cooling water coil and the evaporator, expanding the way to obtain cooled cold air when the temperature of the heat source equipment is lowered by air cooling; through the condenser, it is possible to achieve cooling of the fluid output by the compressor based on the fluid flowing into the pipeline inlet, creating favorable evaporation conditions for the evaporator to cool the ambient air; and improving the efficiency of lowering the temperature of the heat source equipment by air cooling based on the wind wall equipment.

[0120] FIG6 shows a flow chart of a method for controlling a wind wall device according to an exemplary embodiment of the present application. This method can be executed by a computer device. Similar to the computer device in the embodiment shown in FIG4 , the computer device is an electronic device capable of computing, processing, and storing data.

[0121] This method is applied to a wind wall device. FIG7 shows a structural block diagram of a wind wall device provided by an embodiment of the present application. That is, based on the embodiment shown in FIG3 , the wind wall device 1 further includes: a second three-way valve 285 and an eighth pipeline portion 28 .

[0122] a seventh pipe section 27 for connecting the second end of the cooling water coil 11 to the input end of the second three-way valve 285 , and for connecting the first output end of the second three-way valve 285 to the first input end of the condenser 12 ;

[0123] An eighth pipeline portion 28 is used to connect the second output end of the second three-way valve 285 and the pipeline outlet 17;

[0124] The second pipeline portion 22 is used to connect the pipeline inlet 16 and the input end of the second three-way valve 285 , and to connect the first output end of the second three-way valve 285 and the first input end of the condenser 12 .

[0125] In the embodiment shown in FIG7 , for details not yet described about the cooling water coil 11 to the pipe outlet 17 and the first pipe section 21 to the sixth pipe section 26 , please refer to the description in the embodiment corresponding to FIG2 above, which will not be repeated here.

[0126] The control method of the wind wall device includes:

[0127] Step 510: Control the fan to be in an activated state, and reduce the temperature of the heat source device by air cooling based on the air cooled by the cooling water coil and / or the evaporator;

[0128] When the fan is in the started state, the fan draws air from the first side to the second side, thereby reducing the temperature of the heat source equipment in an air-cooling manner on the second side of the fan.

[0129] The air is drawn from the first side of the fan to the second side by the fan under the force of the fan, and then blown to the heat source equipment; on either side of the fan, the air is cooled by the cooling water coil and / or evaporator, thereby reducing the temperature of the heat source equipment by air cooling.

[0130] It should be noted that, in this embodiment, step 510 may be performed before, after, or simultaneously with any step in the second step group, which includes steps 560 to 580. This embodiment does not impose any restrictive provisions on the execution.

[0131] Step 560: Obtain a second temperature at the location of the cooling tower;

[0132] The pipeline inlet is connected to the output end of the cooling tower, and the pipeline outlet is connected to the input end of the cooling tower. The cooling tower is a thermal device that cools the inflowing fluid and discharges the cooled fluid.

[0133] For example, similar to the first temperature mentioned above, this application does not make any restrictive provisions on the measurement method and measurement position of the second temperature.

[0134] Step 570: When the second temperature exceeds a third threshold, obtaining a condensing pressure; and controlling an opening / closing ratio between the first output end and the second output end of the second three-way valve according to the condensing pressure; controlling the compressor to be in an activated state to pressurize the fluid flowing out of the evaporator to obtain a high-pressure fluid;

[0135] When the second temperature exceeds the third threshold, the temperature of the environment where the cooling tower is located is high or medium. When only relying on the fluid flowing out of the output end of the cooling tower to flow to the cooling water coil, the cooling capacity of the ambient air cannot meet the ambient air cooling requirements.

[0136] In an optional example, the third threshold value has the same value as the second threshold value mentioned above. The first threshold value, the second threshold value, the third threshold value and other temperature-related threshold values ​​in each embodiment of the present application can be pre-set. Unless otherwise specified in the embodiment, the settings of different threshold values ​​are usually independent of each other and are not related to each other.

[0137] A condensing pressure is obtained. The condensing pressure indicates the pressure of the pipeline between the second input end and the second output end of the condenser. For example, the condensing pressure can be determined based on the pipeline pressure of the second input end of the condenser, or the pipeline near the second input end. Alternatively, the condensing pressure can be determined based on the pipeline temperature of the second input end of the condenser, or the pipeline near the second input end. Furthermore, the pipeline temperature and the condensing pressure are positively correlated and have a one-to-one correspondence.

[0138] According to the condensing pressure, the opening and closing ratio between the first output end and the second output end of the second three-way valve is controlled (in the embodiment corresponding to Figure 7, this is also called controlling the second three-way valve to be in an adjustment state), so that part of the fluid flowing out from the pipeline inlet continues to flow through the condenser (specifically, part of the fluid continues to flow through the first branch inside the condenser).

[0139] As the condensing pressure increases, the demand for cooling the fluid in the second branch increases. By controlling the opening and closing ratio between the first output end and the second output end of the second three-way valve, the fluid flow rate in the first branch inside the condenser is increased to meet the demand for cooling the fluid in the second branch.

[0140] Similarly, as the condensing pressure decreases, the opening and closing ratio between the first output end and the second output end of the second three-way valve is controlled to decrease, thereby reducing the fluid flow in the first branch inside the condenser to meet the fluid cooling demand in the second branch.

[0141] It can be seen from the above that the opening and closing ratio between the first output end and the second output end of the second three-way valve is positively correlated with the condensing pressure.

[0142] In this step, since the ambient air cooling requirement cannot be met solely by the fluid flowing to the cooling water coil, and the compressor is in the starting state, the fan accordingly lowers the temperature of the heat source device by air cooling based on the air cooled by the cooling water coil and the evaporator; or, the fan lowers the temperature of the heat source device by air cooling based on the air cooled by the evaporator.

[0143] Step 580: When the second temperature does not exceed the third threshold, control the first output end of the second three-way valve to close, guide the fluid flowing out of the pipeline inlet and the fluid flowing out of the second end of the cooling water coil to sequentially pass through the input end and the second output end of the second three-way valve and the eighth pipeline portion, and flow out to the pipeline outlet; and control the compressor to be in a stopped state;

[0144] If the second temperature does not exceed the third threshold, the ambient temperature of the cooling tower is relatively low, and the ambient air cooling requirement can be met solely by the cooling capacity of the fluid flowing out of the cooling tower's output end and into the cooling water coil. This means that the ambient air cooling requirement can be met without starting the compressor.

[0145] When the compressor does not need to be started, the fluid in the second branch of the condenser does not need to be cooled. By controlling the first output end of the second three-way valve to be closed (in the embodiment corresponding to Figure 7, this is also called controlling the second three-way valve to be in a full bypass state), the fluid flowing out of the pipeline inlet is prevented from flowing into the condenser, and part or all of the fluid flowing out of the pipeline inlet is guided to flow out to the pipeline outlet after passing through the cooling water coil.

[0146] In this step, since the fluid flowing to the cooling water coil has the ability to cool the ambient air and the compressor is in a stopped state, the fan accordingly lowers the temperature of the heat source equipment in an air-cooling manner based on the air cooled by the cooling water coil.

[0147] It should be noted that step 530 or step 580 in this embodiment can be combined with step 510 and step 560 to form a new embodiment and implemented separately, and this application does not make any restrictive provisions on this.

[0148] In summary, the method provided in this embodiment provides a seventh pipeline portion and a second three-way valve, enriching the connection mode between the second end of the cooling water coil and the pipeline outlet; providing an opening and closing mode of the second three-way valve at different temperatures; providing a variety of ways to cool the air through the cooling water coil and the evaporator, expanding the way to obtain cooled cold air when the temperature of the heat source equipment is lowered by air cooling; through the condenser, it is possible to achieve cooling of the fluid output by the compressor based on the fluid flowing into the pipeline inlet, creating favorable evaporation conditions for the evaporator to cool the ambient air; and improving the efficiency of lowering the temperature of the heat source equipment by air cooling based on the wind wall equipment.

[0149] FIG8 shows a flow chart of a method for controlling a wind wall device according to an exemplary embodiment of the present application. This method can be executed by a computer device. Similar to the computer device in the embodiment shown in FIG4 , the computer device is an electronic device capable of computing, processing, and storing data.

[0150] This method is applied to a wind wall device. FIG9 shows a structural block diagram of a wind wall device provided by an embodiment of the present application. That is, based on the embodiment shown in FIG2 , the wind wall device 1 further includes: a first valve 215, a second valve 225;

[0151] The first pipe portion 21 is used to connect the pipe inlet 16 with the first end of the first valve 215 , and to connect the second end of the first valve 215 with the first end of the cooling water coil 11 ;

[0152] The second pipeline portion 22 is used to connect the pipeline inlet 16 with the first end of the second valve 225 , and connect the second end of the second valve 225 with the first input end of the condenser 12 .

[0153] Furthermore, the wind wall device 1 further includes: an expansion valve 265;

[0154] The sixth pipe portion 26 is used to connect the second output end of the condenser 12 and the first end of the expansion valve 265 , and to connect the second end of the expansion valve 265 and the input end of the evaporator 14 .

[0155] Illustratively, the fluid flowing out of the second branch of the condenser 12 passes through the expansion valve 265 .

[0156] The expansion valve 265 is internally provided with some channels or nozzles with smaller apertures, and when the fluid flowing out of the second branch of the condenser 12 passes through the expansion valve 265, it expands. This expansion effect can reduce the pressure of the fluid and achieve a cooling effect.

[0157] It should be noted that the expansion valve 265 in this embodiment can be combined with any of the wind wall devices shown in Figures 2, 3, 5, and 7. The expansion valve 265 can be deployed on the sixth pipe section 26 to form a new embodiment.

[0158] The control method of the wind wall device includes:

[0159] Step 510: Control the fan to be in an activated state, and reduce the temperature of the heat source device by air cooling based on the air cooled by the cooling water coil and / or the evaporator;

[0160] When the fan is in the started state, the fan draws air from the first side to the second side, thereby reducing the temperature of the heat source equipment in an air-cooling manner on the second side of the fan.

[0161] The air is drawn from the first side of the fan to the second side by the fan under the force of the fan, and then blown to the heat source equipment; on either side of the fan, the air is cooled by the cooling water coil and / or evaporator, thereby reducing the temperature of the heat source equipment by air cooling.

[0162] It should be noted that, in this embodiment, step 510 may be performed before, after, or simultaneously with any step in the third step group, which includes steps 600 to 630. This embodiment does not impose any restrictive provisions on the execution.

[0163] Step 600: Obtain a third temperature at the location of the cooling tower;

[0164] The pipeline inlet is connected to the output end of the cooling tower, and the pipeline outlet is connected to the input end of the cooling tower. The cooling tower is a thermal device that cools the inflowing fluid and discharges the cooled fluid.

[0165] For example, similar to the first temperature mentioned above, this application does not make any restrictive provisions on the measurement method and measurement position of the third temperature.

[0166] Step 610: When the third temperature exceeds the fourth threshold, the first valve is controlled to close and the second valve is controlled to open, guiding the fluid flowing out of the pipeline inlet through the second valve in the second pipeline portion and out to the first input end of the condenser; and the compressor is controlled to be in the starting state to pressurize the fluid flowing out of the evaporator to obtain high-pressure fluid.

[0167] If the third temperature exceeds the fourth threshold, the temperature of the environment in which the cooling tower is located is high, and even if the fluid flowing out of the output end of the cooling tower flows to the cooling water coil, it will not be able to cool the ambient air. In an optional example, the fourth threshold is the same as the first threshold described above.

[0168] By controlling the first valve to be closed and the second valve to be open, the fluid flowing out of the pipeline inlet is prevented from continuously flowing through the cooling water coil.

[0169] The compressor is controlled to be in the starting state, and the fluid flowing out of the evaporator is pressurized to obtain high-pressure fluid; when the first valve is closed and the second valve is opened, the entire amount of fluid flowing out of the pipeline inlet is guided to the first input end that directly flows into the condenser, and the fluid in the second branch is cooled in the first branch inside the condenser.

[0170] In this step, since the fluid flowing to the cooling water coil does not have the ability to cool the ambient air and the compressor is in the starting state, the fan accordingly lowers the temperature of the heat source equipment in an air-cooling manner based on the air cooled by the evaporator.

[0171] Step 620: When the third temperature does not exceed the fourth threshold value and exceeds the fifth threshold value, the first valve and the second valve are controlled to open, thereby diverting the fluid flowing out of the pipeline inlet to flow through the second pipeline portion to the first input end of the condenser and through the first pipeline portion to the first end of the cooling water coil; and the compressor is controlled to be in an activated state to pressurize the fluid flowing out of the evaporator to obtain a high-pressure fluid.

[0172] When the third temperature does not exceed the fourth threshold and exceeds the fifth threshold, the temperature of the environment surrounding the cooling tower is moderate, and the fluid flowing out of the cooling tower's output end, when flowing to the cooling water coil, is capable of cooling the ambient air. For example, the fourth threshold in this embodiment is greater than the fifth threshold. In an optional example, the fourth threshold is the same as the first threshold described above, and the fifth threshold is the same as the second threshold described above.

[0173] By controlling the opening of the first and second valves, a portion of the fluid flowing out of the pipeline inlet continuously flows through the cooling water coil, cooling the ambient air. Another portion of the fluid flowing out of the pipeline inlet is directed to the first input end of the condenser, where it cools the fluid in the second branch in the first branch inside the condenser.

[0174] In this step, since the fluid flowing to the cooling water coil has the ability to cool the ambient air and the compressor is in the started state, the fan accordingly lowers the temperature of the heat source equipment by air cooling based on the air cooled by the cooling water coil and the evaporator.

[0175] Step 630: When the third temperature does not exceed the fifth threshold, control the first valve to open and the second valve to close, guide the fluid flowing out of the pipeline inlet through the first valve in the first pipeline section and out to the first end of the cooling water coil; and control the compressor to be in a stopped state.

[0176] If the third temperature does not exceed the fifth threshold, the ambient temperature of the cooling tower is relatively low, and the ambient air cooling requirement can be met solely by the cooling capacity of the fluid flowing out of the cooling tower's output end and into the cooling water coil. This means that the ambient air cooling requirement can be met without starting the compressor.

[0177] When the compressor does not need to be started, the fluid in the second branch of the condenser does not need to be cooled. By controlling the opening of the first valve and the closing of the second valve, the fluid flowing out of the pipeline inlet is prevented from flowing into the condenser, and all the fluid flowing out of the pipeline inlet is guided to flow out to the pipeline outlet after passing through the cooling water coil.

[0178] In this step, since the fluid flowing to the cooling water coil has the ability to cool the ambient air and the compressor is in a stopped state, the fan accordingly lowers the temperature of the heat source equipment in an air-cooling manner based on the air cooled by the cooling water coil.

[0179] It should be noted that any of step 610, step 620 and step 630 in this embodiment can be combined with step 510 and step 600 to form a new embodiment and implemented separately, and this application does not make any restrictive provisions on this.

[0180] In summary, the method provided in this embodiment provides a ninth pipeline portion, a first valve, and a second valve, enriching the connection mode between the second end of the cooling water coil and the pipeline outlet; providing the opening and closing modes of the first valve and the second valve at different temperatures; providing a variety of air cooling modes through the cooling water coil and the evaporator, expanding the mode of obtaining cooled cold air when the temperature of the heat source equipment is lowered by air cooling; the condenser can realize cooling of the fluid output by the compressor based on the fluid flowing into the pipeline inlet, creating favorable evaporation conditions for the evaporator to cool the ambient air; and improving the efficiency of lowering the temperature of the heat source equipment by air cooling based on the wind wall equipment.

[0181] Next, the wind wall equipment is further introduced.

[0182] The various hardware components and pipelines in the wind wall device of this application can be centrally deployed in a single housing; or they can be separately deployed in at least two housings, with the two housings connected by pipelines. The various structural block diagrams above only define the connection method between the hardware components, but do not restrict the placement of the hardware components or the arrangement of the pipelines when connecting the hardware components.

[0183] This article introduces how the various hardware components and pipeline parts in the wind wall equipment are centrally deployed in a shell.

[0184] In one example, at least one partition is disposed in the shell to separate the interior of the shell into at least two independent spaces; illustratively, there may be holes on the partition for the pipeline to pass through the partition or provide a channel for air flow.

[0185] In another example, the interior of the housing is a continuous space, and various hardware components are deployed inside.

[0186] FIG10 shows a schematic diagram of a wind wall device provided in one embodiment of the present application.

[0187] The first sub-figure (a) shows how a first partition 41 divides the interior of the housing into an independent upper space 42 and lower space 43. In one example, considering the heavy weight of the condenser 12 and compressor 13, the condenser 12 and compressor 13 are located in the lower space 43, while the cooling water coil, evaporator, and fan are located in the upper space 42. This ensures that the overall center of gravity of the wind wall equipment is close to the lower space, ensuring the stability of the center of gravity of the wind wall equipment and reducing the risk of the wind wall equipment tipping over. In the front view, the cooling water coil, evaporator, and fan overlap in the upper space, which is not shown in the figure.

[0188] The second sub-figure (b) shows that a second partition 45 divides the interior of the housing into mutually independent left and right compartments 46 and 47. In one example, the condenser 12 and compressor 13 are located in the right compartment 47, while the cooling water coil, evaporator, and fan are located in the left compartment 46. In the front view, the cooling water coil, evaporator, and fan overlap in the upper compartment, but this is not shown.

[0189] The third sub-figure c shows that the interior of the shell is a continuous space, with the fan 15 deployed on the left, the cooling water coil 11, the evaporator 14, and the filter 18 deployed on the right, and the condenser 12 and the compressor 13 deployed in the middle.

[0190] Exemplarily, the pipeline inlet 16 and the pipeline outlet 17 are usually arranged on the side of the shell near the bottom; the connection relationship between the various hardware components can be referred to the various structural block diagrams above, which are not shown in Figure 10.

[0191] FIG11 shows a schematic diagram of a wind wall device provided in one embodiment of the present application.

[0192] The fourth sub-figure d shows that the evaporator 14 and the cooling water coil 11 are arranged on a first side of the fan 15;

[0193] The fan 15 is used to pump cold air to the heat source device to reduce the temperature of the heat source device in an air-cooling manner. The cold air is air cooled by the cooling water coil 11 and / or the evaporator 14 .

[0194] The fifth sub-figure e shows that the evaporator 14 and the cooling water coil 11 are arranged on the second side of the fan 15;

[0195] The fan 15 is used to draw ambient air toward the evaporator 14 and the cooling water coil 11, thereby reducing the temperature of the heat source equipment through air cooling. For example, in the fourth sub-figure (d) and the fifth sub-figure (e), a filter 18 is deployed on the air intake side of the fan 15 to prevent debris from being drawn into the wind wall equipment.

[0196] Figure 12 shows a block diagram of a refrigeration system according to an embodiment of the present application. The refrigeration system includes at least one wind wall device 1 and a cooling tower 3;

[0197] In the embodiment shown in Figure 12, the wind wall device 1 includes a cooling water coil 11, a condenser 12, a compressor 13, an evaporator 14, a fan 15, a pipeline inlet 16, a pipeline outlet 17, and the first pipeline section to the sixth pipeline section, as well as the seventh pipeline section, the eighth pipeline section, the expansion valve 265, the first three-way valve 275, and the second three-way valve 285.

[0198] For an introduction to the cooling water coil 11 to the pipe outlet 17, a total of seven hardware components, as well as an introduction to the first to sixth pipe sections, please refer to Figures 1 to 3 above. For an introduction to the seventh and eighth pipe sections, the first three-way valve 275, and the second three-way valve 285, please refer to Figures 3, 5, and 7 above. For an introduction to the expansion valve 265, please refer to Figure 9 above. The introduction to each hardware component and pipe section in the wind wall device 1 will not be repeated in this application.

[0199] It should be noted that FIG12 is only an exemplary introduction, and the wind wall device included in the refrigeration system can be implemented as any one of the wind wall devices in FIG2, FIG3, FIG5, FIG7, and FIG9 above.

[0200] The cooling tower 3 is a thermal device that cools incoming fluid and discharges the cooled fluid. The cooling tower 3 can be implemented as a closed cooling tower. The pipe inlet 16 of the wind wall device 1 is connected to the output end 31 of the cooling tower 3, and the pipe outlet 17 of the wind wall device 1 is connected to the input end 32 of the cooling tower 3.

[0201] In an optional example, the system further includes at least one liquid cooling device 2;

[0202] The first end of the liquid cooling device 2 is connected to the output end 31 of the cooling tower 3, and the second end of the liquid cooling device 2 is connected to the input end 32 of the cooling tower 3. The liquid cooling device 2 is used to reduce the temperature of the heat source device by liquid cooling according to the inflowing fluid.

[0203] Furthermore, a third valve 2a is deployed at the first end of the liquid cooling device 2, and a fourth valve 2b is deployed at the second end of the liquid cooling device 2; illustratively, the third valve 2a and the fourth valve 2b are inspection valves of the liquid cooling device 2. In one example, the third valve 2a and the fourth valve 2b remain in a normally open state.

[0204] In a further optional example, the cooling tower 3 includes a first pump body 33;

[0205] The input end 32 of the cooling tower 3 is connected to the input end of the first pump body 33; the first output end of the first pump body is connected to the pipeline inlet 16 of the wind wall device 1; the second output end of the first pump body is connected to the first end of the liquid cooling device 2.

[0206] Further introduction to liquid cooling equipment 2 and cooling tower 3:

[0207] In one example, the cooling tower 3 further includes a second pump body 34, which is used to spray the liquid in the water collection tray 35 of the cooling tower 3 onto the pipeline between the input end 32 and the output end 31 of the cooling tower 3. Furthermore, the liquid is sprayed onto the first pipeline 3a between the input end 32 and the output end of the cooling tower 3. The first pipeline 3a can be implemented as an evaporation pipe row. The liquid in the water collection tray 35 of the cooling tower 3 flows through the second pump body 34 (also called a spray pump) to the nozzle at the top of the cooling tower 3 and is sprayed out. The spray water evaporates and absorbs heat under the interaction with the air, cooling the fluid in the first pipeline 3a. The heated spray water is evaporated and cooled in the cooling tower filler 36, and then returns to the water collection tray 35. The cooling tower 3 also includes a second pipeline 3b, which can be implemented as a tube-fin dry cooler. The fluid in the second pipeline 3b is cooled by the cold air outside. Exemplarily, the pipeline between the input end 32 and the output end 31 of the cooling tower 3 is at least one of the first pipeline 3a and the second pipeline 3b.

[0208] In one example, the liquid cooling device 2 further includes a chilled distribution unit (CDU) for distributing liquid cooling water, which passes through a plate heat exchanger in the liquid cooling device 2 and then flows back to the cooling tower 3 through a fourth valve 2 b.

[0209] It should be noted that the number of liquid cooling devices 2 can be one or more; similarly, the number of air wall devices 1 can also be one or more. The ratio of the number of liquid cooling devices 2 to air wall devices 1 can be determined based on the size of the space where the heat source equipment is located (such as a computer room), the heat dissipation requirements of the heat source equipment, etc.

[0210] FIG13 shows a flow chart of a method for controlling a refrigeration system according to an exemplary embodiment of the present application. This method can be executed by a computer device. Similar to the computer device in the embodiment shown in FIG4 , the computer device is an electronic device capable of computing, processing, and storing data.

[0211] The method is applied to a refrigeration system shown in FIG12 above. The control method of the refrigeration system includes:

[0212] Step 710: Control the fan of the wind wall device to be in the starting state, and reduce the temperature of the heat source device in an air cooling manner based on the air cooled by the cooling water coil and / or evaporator of the wind wall device.

[0213] When the fan is in the started state, the fan draws air from the first side to the second side, thereby reducing the temperature of the heat source equipment in an air-cooling manner on the second side of the fan.

[0214] It should be noted that, in this embodiment, step 710 may be performed before, after, or simultaneously with any step in the fourth step group, which includes steps 720 to 746. This embodiment does not impose any restrictive provisions on the execution.

[0215] It should be noted that step 710 can be implemented independently as a new embodiment; accordingly, the above new embodiment is applied to a refrigeration system, which includes at least one wind wall device and a cooling tower. The wind wall device can be implemented as any of the wind wall devices in Figures 2, 3, 5, 7, and 9 above; please refer to the description of the cooling tower in Figure 12.

[0216] It should be noted that step 710 and step 520 described above can be combined with at least one of steps 530, 540, and 550 to form a new embodiment and be implemented separately. Step 710 and step 560 described above can be combined with at least one of steps 570 and 580 to form a new embodiment and be implemented separately. Step 710 and step 600 described above can be combined with at least one of steps 610, 620, and 630 to form a new embodiment and be implemented separately. This application does not limit this.

[0217] Step 720: Control the liquid cooling device to be in an activated state, and reduce the temperature of the heat source device by liquid cooling based on the fluid flowing into the liquid cooling device;

[0218] For example, when the liquid cooling device is in the startup state, the refrigeration distribution unit in the liquid cooling device distributes liquid cooling water, which exchanges heat through the plate heat exchanger in the liquid cooling device to reduce the temperature of the heat source device in a liquid cooling manner.

[0219] It should be noted that, in this embodiment, step 720 may be performed before, after, or simultaneously with any step in the fifth step group, which includes steps 732 to 746. This embodiment does not impose any restrictive provisions on the execution.

[0220] It should be noted that steps 710 and 720 can be implemented separately as a new embodiment; accordingly, the above new embodiment is applied to a refrigeration system, which includes at least one wind wall device, a cooling tower, and a liquid cooling device. The wind wall device can be implemented as any of the wind wall devices shown in Figures 2, 3, 5, 7, and 9 above; please refer to the description of the cooling tower and liquid cooling device in Figure 12.

[0221] Step 732: Obtain a fourth temperature at the location of the heat source device;

[0222] For example, the fourth temperature may be the ambient temperature at the location of the heat source device, or the device temperature on the surface or inside the heat source device. For example, the fourth temperature may be a temperature measured using a dry-bulb method or a temperature measured using a wet-bulb method.

[0223] Step 734: Control the opening and closing ratio between the first output end and the second output end of the first pump body according to the fourth temperature.

[0224] For example, the liquid cooling device can usually be placed close to the heat-generating panels of the heat source device, etc., inside or near the heat source device, to reduce the temperature of the heat source device by liquid cooling.

[0225] For example, when the same flow rate of cooling fluid is obtained from the cooling tower, the liquid cooling device is more effective in reducing the temperature of the heat source device than the wind wall device.

[0226] The fourth temperature can indicate the heat dissipation demand of the heat source device. As the fourth temperature increases, the heat dissipation demand of the heat source device increases. By controlling the opening and closing ratio between the first output end and the second output end of the first pump body, the fluid flow rate flowing into the wind wall device is reduced, and the fluid flow rate flowing into the liquid cooling device is increased; thereby improving the ability to dissipate heat for the heat source device to match the heat dissipation demand of the heat source device.

[0227] On the contrary, as the fourth temperature decreases, the heat dissipation demand of the heat source device decreases. By controlling the opening and closing ratio between the first output end and the second output end of the first pump body, the fluid flow rate flowing into the wind wall device is increased, and the fluid flow rate flowing into the liquid cooling device is reduced; thereby reducing the ability to dissipate heat to the heat source device to match the heat dissipation demand of the heat source device.

[0228] It can be seen from the above that the opening and closing ratio between the first output end and the second output end of the first pump body is inversely correlated with the fourth temperature.

[0229] It should be noted that step 710, step 720, step 732, and step 734 can be implemented separately as a new embodiment; accordingly, the above-mentioned new embodiment is applied to a refrigeration system, which includes at least one wind wall device, a cooling tower and a liquid cooling device, and the cooling tower includes a first pump body.

[0230] Step 742: Acquire a fifth temperature;

[0231] For example, the first temperature may be the ambient temperature at the location of the cooling tower, or the temperature of the fluid at or near the output end of the cooling tower. The fifth temperature is the dry-bulb temperature at the location of the cooling tower;

[0232] Step 744: When the fifth temperature exceeds the sixth threshold, control the second pump to start;

[0233] The cooling tower includes a second pump body, which is used to spray the liquid in the water collection tray of the cooling tower onto the pipeline between the input end and the output end of the cooling tower; the spraying water evaporates and absorbs heat under the interaction with the air, cooling the fluid in the pipeline between the input end and the output end of the cooling tower.

[0234] When the fifth temperature exceeds the sixth threshold, cooling the fluid in the internal pipes of the cooling tower by relying solely on the outdoor cold air where the cooling tower is located cannot meet the need to cool the heat source equipment.

[0235] By controlling the start-up of the second pump body, the fluid in the internal pipeline of the cooling tower is further cooled by spraying water.

[0236] Step 746: When the fifth temperature does not exceed the sixth threshold, control the second pump to stop; and control the compressor to be in a stopped state.

[0237] When the fifth temperature exceeds the sixth threshold, the need to cool the heat source equipment can be met by cooling the fluid in the internal pipes of the cooling tower only by relying on the outdoor cold air where the cooling tower is located.

[0238] By stopping the second pump and controlling the compressor to be in a stopped state, spray water is no longer used to further cool the fluid in the cooling tower's internal pipes. In this step, because the fluid flowing through the cooling water coil has the ability to cool the ambient air, and the compressor is in a stopped state, the fan, based on the cooled air passing through the cooling water coil, cools the heat source equipment through air cooling.

[0239] It should be noted that step 710, step 742, step 744, and step 746 can be implemented separately as a new embodiment; accordingly, the above-mentioned new embodiment is applied to a refrigeration system, which includes at least one wind wall device and a cooling tower, and the cooling tower includes a second pump body.

[0240] In summary, the method provided in this embodiment provides multiple ways to cool the air through the cooling water coil and the evaporator, expanding the way to obtain cooled cold air when lowering the temperature of the heat source equipment by air cooling; through the condenser, it can achieve the cooling of the fluid output by the compressor based on the fluid flowing into the pipeline inlet, creating favorable evaporation conditions for the evaporator to cool the ambient air; and improves the efficiency of lowering the temperature of the heat source equipment by air cooling based on the wind wall device.
