[0001] The present disclosure relates to the field of container machine rooms, and more specifically to a container machine room air supply and return system and method. Background Art

[0002] The temperature in the container room needs to be maintained within a certain range so that the power distribution equipment and IT equipment can operate normally. However, the operating environment temperature of the power distribution equipment is usually higher than that of the IT equipment, and in order to ensure equipment safety and maximize the capacity of IT equipment, these power distribution equipment and IT equipment should not be placed together. Therefore, the power distribution equipment and IT equipment are generally physically isolated, with batteries and power distribution equipment placed in the power distribution room and IT equipment placed in the cabinet room.

[0003] Since container machine rooms are usually placed outdoors, they need to be equipped with refrigeration equipment to prevent the equipment inside the container machine room from being heated, especially in the high temperature outdoor environment in summer, the distribution room may have the risk of overheating. In the existing method, refrigeration equipment can be configured for the distribution room alone, but the refrigeration equipment will occupy space and cause waste of resources. Summary of the invention

[0004] In view of the above problems, the present disclosure provides a container machine room air supply and return system and method.

[0031] It should be noted that the container machine room air supply and return system and method of the embodiments of the present disclosure can be applied to the financial field, for example, for ventilation and heat dissipation of the container machine room, and can also be used in any field other than the financial field. The application field of the container machine room air supply and return system and method of the embodiments of the present disclosure is not limited.

[0032] The embodiment of the present disclosure provides a container machine room air supply and return system, including: a box body 1; a cabinet room 2, located in the box body 1; a refrigeration device 3, arranged in the box body 1, and the refrigeration device 3 is connected to the cabinet room 2; a power distribution room 4, located in the box body 1, and the power distribution room 4 is connected to the cabinet room 2 through a first air duct 5 and a second air duct 6, so that the cabinet room 2, the first air duct 5, the power distribution room 4 and the second air duct 6 are connected in sequence to form a loop; and a heat exchange device 7, arranged outside the box body 1, the air outlet duct 71 of the heat exchange device 7 is connected to the first air duct 5, and the air inlet duct 72 of the heat exchange device 7 is connected to the second air duct 6. Through the above design, the refrigeration device 3 inherent in the container machine room and the heat exchange device 7 located outside the container machine room can be used to coordinate and cooperate to achieve cooling of the internal environment of the container machine room, and avoid excessive temperature affecting the operation of equipment in the power distribution room 4 and the cabinet room 2.

[0033] Figure 1 The top view of the structure of the container room air supply and return system according to the embodiment of the present disclosure is schematically shown. Figure 2 A side structural diagram of a container machine room supply and return air system according to an embodiment of the present disclosure is schematically shown.

[0034] like Figure 1 and Figure 2 As shown, according to this embodiment, the container room air supply and return system may include a box body 1, a cabinet room 2, a refrigeration device 3, a power distribution room 4 and a heat exchange device 7, which are used to cool down the batteries, power distribution equipment and IT equipment in the container room.

[0035] The box 1 may be a conventional container shell for accommodating various devices. The box 1 is generally arranged in an outdoor environment and used as a data center. A floor overhead space may be provided at the bottom of the box 1 for routing cables.

[0036] The cabinet room 2 is a part of the internal space of the box 1 and is used to store IT equipment such as servers. The temperature in the cabinet room 2 should not be too high to avoid affecting the IT equipment.

[0037] The refrigeration equipment 3 is arranged in the box body 1 and is separated from the cabinet room 2. The refrigeration equipment 3 is connected to the cabinet room 2 through different channels. Among them, the channel through which the refrigeration equipment 3 provides cold air to the cabinet room 2 is the cold channel 21, and the channel through which the hot air in the cabinet room 2 enters the refrigeration equipment 3 is the hot channel 22. The cold channel 21 and the hot channel 22 form a loop for cooling the cabinet room 2.

[0038] For example, the refrigeration device 3 may be an air conditioner, which is used to provide uninterrupted cold air to the cabinet room 2, so as to adjust the temperature of the cabinet room 2. Specifically, the cold air generated by the air conditioner enters the cabinet room 2 through the cold channel 21, passes through the cabinet room 2 and cools down the IT equipment such as servers therein, and the newly generated hot air enters the hot channel 22 through the back of the IT equipment, and finally enters the air conditioner for circulation cooling.

[0039] The power distribution room 4 is a part of the internal space of the box 1, and is used to store batteries and power distribution equipment, such as various equipment cabinets such as battery cabinets, UPS cabinets, incoming line cabinets, inverter cabinets, high-voltage DC cabinets, etc. The power distribution room 4 is separated from the cabinet room 2 by a partition, and the refrigeration equipment 3 is arranged on the side of the cabinet room 2 away from the power distribution room 4. The box 1 is provided with a first air duct 5 and a second air duct 6. The power distribution room 4 is connected to the cold channel 21 of the cabinet room 2 through the first air duct 5, and the power distribution room 4 is connected to the hot channel 22 of the cabinet room 2 through the second air duct 6, so that a circulation loop can be formed between the power distribution room 4 and the cabinet room 2. As a result, the cold air generated by the refrigeration equipment 3 can reach the power distribution room 4 after passing through the cold channel 21 and the first air duct 5, and the hot air after cooling and heat exchange can return to the refrigeration equipment 3 after passing through the second air duct 6 and the hot channel 22, so that the cabinet room 2 and the power distribution room 4 can be cooled and cooled by the refrigeration equipment 3 at the same time, saving space and avoiding equipment safety risks caused by high temperature.

[0040] The heat exchange device 7 is arranged outside the box 1, and is used to coordinate with the refrigeration device 3 to cool down the internal environment of the container room and maintain the stable operation of the equipment. The heat exchange device 7 includes an outlet duct 71 and an inlet duct 72. The hot air with a higher temperature enters the heat exchange device 7 through the inlet duct 72, and the cold air with a lower temperature after heat exchange and cooling is discharged from the heat exchange device 7 through the outlet duct 71. Specifically, the inlet duct 72 of the heat exchange device 7 is connected to the second air duct 6, and the outlet duct 71 of the heat exchange device 7 is connected to the first air duct 5. As a result, the hot air in the box 1 can enter the heat exchange device 7 through the second air duct 6 and the inlet duct 72, and the cold air after heat exchange and cooling can flow back to the box 1 through the outlet duct 71 and the first air duct 5, thereby forming a circulation loop for cooling the inside of the box 1.

[0041] In the embodiment of the present disclosure, the first air duct 5 and the second air duct 6 are arranged so that the internal spaces of the cabinet room 2 and the power distribution room 4 are interconnected, and the refrigeration equipment 3 can be used to simultaneously deliver cold air to the cabinet room 2 and the power distribution room 4, which can save space and solve the problem of excessively high internal ambient temperature of the outdoor container room in summer. In addition, a heat exchange device 7 is arranged outside the box body 1, and the heat exchange device 7 is connected to the power distribution room 4 and the cabinet room 2 through the first air duct 5 and the second air duct 6. The heat exchange device 7 can be used to supply cooling to the power distribution room 4 and the cabinet room 2, maintain the temperature in the power distribution room 4 and the cabinet room 2, and reduce the energy consumption of the refrigeration device 3.

[0042] The container room air supply and return system according to the embodiment of the present disclosure further includes a heat exchange room 8 disposed between the cabinet room 2 and the power distribution room 4, and the first air duct 5 and the second air duct 6 both pass through the heat exchange room 8. The heat exchange room 8 is a part of the internal space of the box body 1, and the two sides of the heat exchange room 8 are separated from the power distribution room 4 and the cabinet room 2 by partitions.

[0043] For example, Figure 1 As shown, from left to right in the figure are the power distribution room 4, the heat exchange room 8, the cabinet room 2 and the refrigeration equipment 3, respectively, and the first air duct 5 and the second air duct 6 extend from left to right. The first air duct 5 runs through the heat exchange room 8, one end of the first air duct 5 is connected to the power distribution room 4, and the other end of the first air duct 5 is connected to the cold channel 21 in the cabinet room 2. The second air duct 6 runs through the heat exchange room 8, one end of the second air duct 6 is connected to the power distribution room 4, and the other end of the second air duct 6 is connected to the hot channel 22 in the cabinet room 2. As a result, the cold air of the refrigeration equipment 3 can enter the power distribution room 4 through the cold channel 21 and the first air duct 5, and the hot air formed by the cold air after heat exchange can return to the refrigeration equipment 3 through the second air duct 6 and the hot channel 22, so as to achieve cooling of the cabinet room 2 and the power distribution room 4 at the same time.

[0044] It should be noted that the first air duct 5 and the second air duct 6 may be tubular structures such as round tubes and square tubes, and the structures of the first air duct 5 and the second air duct 6 may be the same or different, as long as the air passages can be connected.

[0045] According to an embodiment of the present disclosure, the first air duct 5 has a first vent 53 for communicating with the distribution room 4, and the second air duct 6 has a second vent 63 for communicating with the distribution room 4, and the second vent 63 and the first vent 53 are arranged in sequence along a first direction, wherein the first direction is toward the bottom surface of the box body 1 and is perpendicular to the bottom surface of the box body 1.

[0046] For example, Figure 2 As shown, the first direction L is the gravity direction of the box body 1, the first vent 53 is located near the bottom surface of the box body 1, and the second vent 63 is located near the top surface of the box body 1. When the refrigeration equipment 3 supplies air, the cold air blown in through the first air duct 5 enters from the bottom of the power distribution room 4, and the cold air becomes hot air after heat exchange in the power distribution room 4. Since the density of hot air is smaller than that of cold air, the hot air will gather at the top of the power distribution room 4, so that the hot air is blown into the second air duct 6 from the second vent 63 located at the top of the power distribution room 4. Therefore, arranging the second vent 63 and the first vent 53 up and down can improve the circulation efficiency of cold air and hot air in the power distribution room 4, so that the heat exchange and cooling efficiency is higher.

[0047] According to an embodiment of the present disclosure, the first vent 53 and the second vent 63 are respectively close to the two sides of the box body 1. Figure 2As shown, the first vent 53 is close to the left side of the box body 1, and the second vent 63 is close to the right side of the box body 1. Specifically, the first vent 53 is located at the lower left corner, and the second vent 63 is located at the upper right corner. The cold air input by the first air duct 5 enters from the lower left corner of the power distribution room 4, and the hot air after heat exchange is discharged from the upper right corner of the power distribution room 4 to the second air duct 6. Therefore, the first vent 53 and the second vent 63 are arranged on the left and right, which is more conducive to the air flow in the power distribution room 4, and the cold air can fully cover the space in the power distribution room 4, ensuring the cooling effect in the power distribution room 4.

[0048] According to an embodiment of the present disclosure, the first air duct 5 is parallel to the second air duct 6 and parallel to the bottom surface of the box body 1. Figure 1 As shown, the first air duct 5 and the second air duct 6 are both long straight pipes, and the extension direction of the first air duct 5 and the second air duct 6 is parallel to the length direction of the box body 1. In this way, the connecting air path between the cabinet room 2 and the power distribution room 4 can be made shortest, which can reduce the cooling loss of the cold air in the first air duct 5, and facilitate the use of cold air to cool the power distribution room 4.

[0049] According to an embodiment of the present disclosure, the heat exchange equipment 7 is located between the cabinet room 2 and the power distribution room 4 , and the heat exchange equipment 7 is connected to the outer wall of the heat exchange room 8 . The heat exchange equipment 7 can cooperate with the refrigeration equipment 3 to cool the power distribution room 4 and the cabinet room 2 .

[0050] For example, Figure 1 and Figure 2 As shown, the heat exchange device 7 is located on the top outer wall of the heat exchange room 8, and is used to ventilate and cool the internal environment of the box body 1. The air inlet duct 72 of the heat exchange device 7 is connected to the second air duct 6, and the connecting point between the air inlet duct 72 and the second air duct 6 is located in the heat exchange room 8. Therefore, the hot air from the second air duct 6 can enter the heat exchange device 7 through the air inlet duct 72, and the hot air forms cold air after heat exchange and cooling in the heat exchange device 7. The cold air can enter the first air duct 5 through the air outlet duct 71, thereby achieving heat exchange and cooling of the internal environment of the box body 1.

[0051] According to an embodiment of the present disclosure, the heat exchange device 7 may be an air heat exchanger, that is, the cold source of the external environment of the box 1 is used as a heat exchange medium to exchange heat and cool the hot air inside the box 1. For example, in an embodiment of the present disclosure, when the temperature of the external environment of the box 1 is low, the cold air of the external environment may be used as a heat exchange medium to exchange heat and cool the hot air inside the box 1. The hot air in the box 1 is exchanged with the cold air of the external environment by the air heat exchanger, and the hot air inside the box 1 is exchanged with heat and cooled by the natural cold air from the outside, thereby realizing the refrigeration function of the heat exchange device 7.

[0052] It should be noted that the specific form of the heat exchange device 7 is not required in the embodiments of the present disclosure, as long as it can exchange heat and cool the hot air in the box 1. For example, in other embodiments, the heat exchange device 7 can also use cold water / ice water as the heat exchange medium to exchange heat and cool the hot air inside the box 1.

[0053] According to the embodiment of the present disclosure, the container room air supply and return system also includes a first temperature sensor and a second temperature sensor. The first temperature sensor (not shown in the figure) is arranged outside the box 1, and is used to monitor the temperature of the external environment of the box 1. The second temperature sensor (not shown in the figure) is arranged in the power distribution room 4, and is used to monitor the temperature inside the power distribution room 4. The external environment temperature of the box 1 and the temperature of the power distribution room 4 are monitored and compared by the first temperature sensor and the second temperature sensor respectively. Therefore, when it is monitored that the external environment temperature of the box 1 is lower than the temperature of the power distribution room 4, the heat exchange device 7 can be turned on to use the external cold air to cool down the power distribution room 4. In addition, the lower the temperature of the external environment of the box 1, the better the heat exchange effect of the heat exchange device 7.

[0054] According to the embodiment of the present disclosure, a first fan 51 is provided at one end of the first air duct 5 close to the cabinet room 2, a second fan 52 is provided at one end of the first air duct 5 close to the power distribution room 4, a connection point between the first air duct 5 and the air outlet duct 71 is located between the first fan 51 and the second fan 52, a third fan 61 is provided at one end of the second air duct 6 close to the power distribution room 4, a fourth fan 62 is provided at one end of the second air duct 6 close to the cabinet room 2, and a connection point between the second air duct 6 and the air inlet duct 72 is located between the third fan 61 and the fourth fan 62. In this embodiment, the first fan 51, the second fan 52, the third fan 61 and the fourth fan 62 provide power for the air flow inside the box 1.

[0055] For example, Figure 1 As shown, the first fan 51 and the second fan 52 are both arranged inside the first air duct 5, and are used to provide power for the cold air inside the box 1. In addition, the connection point between the air outlet duct 71 of the heat exchange device 7 and the first air duct 5 is located between the first fan 51 and the second fan 52. Therefore, when the refrigeration device 3 or the heat exchange device 7 is working, the second fan 52 can blow the cold air from the refrigeration device 3 or the heat exchange device 7 into the power distribution room 4, thereby cooling the internal environment of the power distribution room 4; when the refrigeration device 3 is working, the first fan 51 and / or the second fan 52 can blow the cold air from the refrigeration device 3 into the power distribution room 4 for cooling; when the heat exchange device 7 is working and the refrigeration device 3 is not working, the second fan 52 can blow the cold air from the heat exchange device 7 into the power distribution room 4 for cooling, and at the same time, the first fan 51 can blow the cold air from the heat exchange device 7 into the cabinet room 2, thereby cooling the internal environment of the cabinet room 2.

[0056] In the embodiment of the present disclosure, the third fan 61 and the fourth fan 62 are both arranged inside the second air duct 6 to provide power for the hot air inside the box body 1. In addition, the connection point between the air inlet duct 72 of the heat exchange device 7 and the second air duct 6 is located between the third fan 61 and the fourth fan 62. Therefore, when the refrigeration device 3 and the heat exchange device 7 are working at the same time, the third fan 61 can blow the hot air from the power distribution room 4 into the heat exchange device 7, and the fourth fan 62 can blow the hot air from the power distribution room 4 into the refrigeration device 3 for cooling; when the heat exchange device 7 is working and the refrigeration device 3 is not working, the third fan 61 can blow the hot air from the power distribution room 4 into the heat exchange device 7, and the fourth fan 62 can blow the hot air from the cabinet room 2 into the heat exchange device 7 for cooling.

[0057] Specifically, the container room air supply and return system of the embodiment of the present disclosure also includes a controller, which is electrically connected to the first fan 51, the second fan 52, the third fan 61 and the fourth fan 62. The rotation speed of the first fan 51, the second fan 52, the third fan 61 and the fourth fan 62 can be adjusted by the controller, and the direction of the first fan 51 and the fourth fan 62 can also be adjusted, so that the first fan 51 and the fourth fan 62 supply air to the left or right. Thus, the first air duct 5 can be used to send the cold air of the cold channel 21 of the cabinet room 2 to the power distribution room 4 or the cold air of the heat exchange equipment 7 to the cold channel 21 of the power distribution room 4 and the cabinet room 2, and the second air duct 6 can be used to send the hot air of the power distribution room 4 back to the hot channel 22 of the cabinet room 2 or send the hot air of the power distribution room 4 and the cabinet room 2 to the heat exchange equipment 7, so that the refrigeration equipment 3 and the heat exchange equipment 7 cooperate to supply cold air to the cabinet room 2 and the power distribution room 4.

[0058] In some optional embodiments, the controller is electrically connected to the first temperature sensor and the second temperature sensor, so that the controller can obtain the external ambient temperature of the box 1 and the temperature of the distribution room 4, and adjust the working conditions of the refrigeration equipment 3 and the heat exchange equipment 7 according to the temperature difference between the external ambient temperature of the box 1 and the temperature of the distribution room 4.

[0059] Based on the above design, the container room air supply and return system of the embodiment of the present disclosure has at least the following four operating modes:

[0060] Mode 1: Heat exchange equipment 7 provides cooling to power distribution room 4 alone

[0061] When the external ambient temperature of the box 1 is lower than the temperature of the distribution room 4 (such as in spring and autumn), the heat exchange device 7 can be used to independently cool the distribution room 4. At this time, the heat exchange device 7 works while the refrigeration device 3 does not work, and the second fan 52 and the third fan 61 work while the first fan 51 and the fourth fan 62 do not work.

[0062] Figure 3The wind flow diagram of the container room supply and return air system in mode 1 according to an embodiment of the present disclosure is schematically shown.

[0063] For example, Figure 3 As shown, the heat exchange device 7 can be an air heat exchanger, which can use the natural cold source outside the box 1 to independently cool the power distribution room 4. Specifically, the second fan 52 blows the cold air from the air heat exchanger into the power distribution room 4. After the cold air is heat-exchanged in the power distribution room 4 and becomes hot air, the third fan 61 blows the hot air in the power distribution room 4 into the air heat exchanger to exchange heat with the cold air outside the box 1 for cooling.

[0064] Optionally, in order to ensure that the cold air from the heat exchange equipment 7 is only used to provide cooling for the distribution room 4, valves such as solenoid valves can be set on the first air duct 5 and the second air duct 6 to block the connection between the first air duct 5 and the second air duct 6 and the cabinet room 2, so that a circulating air path is formed between the heat exchange equipment 7 and the distribution room 4.

[0065] Mode 2: Heat exchange equipment 7 and refrigeration equipment 3 provide cooling to power distribution room 4 at the same time

[0066] When the external environment temperature of the cabinet 1 is slightly lower than the temperature of the power distribution room 4 (such as in late spring and early autumn), the heat exchange device 7 can still work, but the heat exchange device 7 alone cannot maintain the power distribution room 4 at a suitable temperature, so the heat exchange device 7 and the refrigeration device 3 can be used to cool the power distribution room 4 at the same time. At this time, the heat exchange device 7 and the refrigeration device 3 are all working, and the first fan 51, the second fan 52, the third fan 61 and the fourth fan 62 are all working.

[0067] Figure 4 The wind flow diagram of the container room supply and return air system in mode 2 according to an embodiment of the present disclosure is schematically shown.

[0068] For example, Figure 4 As shown, the first fan 51 delivers the cold air from the refrigeration equipment 3 into the first air duct 5, the second fan 52 delivers the cold air from the heat exchange equipment 7 and the refrigeration equipment 3 into the distribution room 4, and the third fan 61 delivers the hot air from the distribution room 4 into the second air duct 6. A part of the hot air entering the second air duct 6 enters the heat exchange equipment 7 through the air inlet pipe 72, and the other part is sent back to the refrigeration equipment 3 by the fourth fan 62, thereby realizing the heat exchange equipment 7 and the refrigeration equipment 3 together supplying cooling to the distribution room 4.

[0069] Mode 3: Refrigeration equipment 3 supplies cooling to power distribution room 4 alone

[0070] When the external ambient temperature of the box body 1 is higher than the temperature of the distribution room 4 (such as in summer), the heat exchange device 7 cannot cool. At this time, the heat exchange device 7 is shut down and the refrigeration device 3 works normally, and the first fan 51, the second fan 52, the third fan 61 and the fourth fan 62 are all working.

[0071] Figure 5 The wind flow diagram of the container room supply and return air system in mode three according to an embodiment of the present disclosure is schematically shown.

[0072] For example, Figure 5 As shown, the first fan 51 and the second fan 52 send the cold air from the refrigeration equipment 3 into the distribution room 4, and the third fan 61 and the fourth fan 62 send all the hot air from the distribution room 4 back to the refrigeration equipment 3, so that the refrigeration equipment 3 can cool the cabinet room 2 and the distribution room 4 separately.

[0073] Optionally, the temperature of the distribution room 4 can also be monitored by a second temperature sensor. When the temperature is high in summer, the rotation speed of the first fan 51 and the second fan 52 or the power of the refrigeration equipment 3 can be adjusted in real time, thereby adjusting the supply and return air speeds in the first air duct 5 and the second air duct 6 and the cold air temperature of the refrigeration equipment 3, thereby ensuring that the temperature of the distribution room 4 is maintained within a certain temperature range.

[0074] Mode 4: Heat exchange equipment 7 provides cooling to both power distribution room 4 and cabinet room 2

[0075] When the ambient temperature of the cabinet 1 is much lower than the temperature of the power distribution room 4 (such as in winter), the cooling effect of the heat exchange device 7 is the best. At this time, the heat exchange device 7 can not only meet the cooling demand of the power distribution room 4, but also send part of the cold air into the cabinet room 2 to cool the IT equipment, that is, the heat exchange device 7 can be used to cool the power distribution room 4 and the cabinet room 2 at the same time. At this time, the heat exchange device 7 works while the refrigeration device 3 does not work, and the first fan 51, the second fan 52, the third fan 61 and the fourth fan 62 are all working.

[0076] Figure 6 The wind flow diagram of the container room supply and return air system in mode 4 according to an embodiment of the present disclosure is schematically shown.

[0077] For example, Figure 6 As shown, the second fan 52 blows the cold air from the heat exchange device 7 into the power distribution room 4 to cool the power distribution room 4, the first fan 51 blows the cold air from the heat exchange device 7 into the cabinet room 2 to cool the cabinet room 2, the third fan 61 blows the hot air from the power distribution room 4 into the heat exchange device 7, and the fourth fan 62 blows the hot air from the cabinet room 2 into the heat exchange device 7. As a result, part of the cold air generated by the heat exchange device 7 is sent to the power distribution room 4 through the second fan 52, and the other part is sent to the cabinet room 2 through the first fan 51. The heat exchange device 7 not only provides cooling for the power distribution room 4, but also delivers cold air to the cabinet room 2, which can reduce the time of starting the refrigeration device 3, reduce the energy consumption of the refrigeration device 3, and save resources.

[0078] Based on the container machine room air supply and return system of the above embodiment, the embodiment of the present disclosure also provides a container machine room air supply and return method. Figure 7 The method is described in detail.

[0079] Figure 7 The flowchart of the container machine room air supply and return method according to the embodiment of the present disclosure is schematically shown.

[0080] like Figure 7 As shown, according to the container machine room return air method of this embodiment, it includes: determining whether the temperature of the power distribution room 4 exceeds a preset value, wherein the preset value may be a set temperature critical value of the power distribution room 4 (the temperature critical value may be set according to the actual operation conditions of the equipment, for example, the preset value may be 30°C, 32°C, etc.). When the temperature of the power distribution room 4 exceeds the preset value, the equipment in the power distribution room 4 may have safety risks caused by high temperature, so it is necessary to control the temperature of the power distribution room 4 not to exceed the preset value.

[0081] If it is monitored that the temperature of the power distribution room 4 exceeds a preset value and a larger cooling capacity is required, the heat exchange device 7 and the refrigeration device 3 can be used to cool the power distribution room 4 at the same time.

[0082] If the temperature of the power distribution room 4 does not exceed the preset value, at least one of the heat exchange device 7 and the refrigeration device 3 can be considered for cooling. Specifically, the temperature difference between the ambient temperature of the cabinet 1 and the temperature of the power distribution room 4 can be determined, and it can be determined whether the temperature difference exceeds the preset temperature range. The preset temperature range can be a set temperature range (which can be set according to actual conditions), for example, the preset temperature range can be 10°C, 12°C, etc.

[0083] If the temperature difference between the external environment temperature of the box 1 and the temperature of the distribution room 4 exceeds the preset temperature range, it means that the external environment temperature of the box 1 is much lower than the temperature of the distribution room 4. At this time, the heat exchange efficiency between the heat exchange equipment 7 and the external environment of the box 1 is relatively high, and the heat exchange equipment 7 can be used to provide cooling for the distribution room 4 and the cabinet room 2 at the same time.

[0084] If the temperature difference between the external ambient temperature of the cabinet 1 and the temperature of the power distribution room 4 does not exceed the preset temperature range, and the external ambient temperature of the cabinet 1 is lower than the temperature of the power distribution room 4, the heat exchange equipment 7 can still be used. At this time, the heat exchange equipment 7 can be used to cool the power distribution room 4 alone.

[0085] When the temperature of the power distribution room 4 is lower than a preset value, the refrigeration equipment 3 and the heat exchange equipment 7 are stopped from sending back air.

[0086] Through the above method, according to the temperature of the distribution room 4 and the external environment temperature of the box 1, at least one of the heat exchange equipment 7 and the refrigeration equipment 3 can be reasonably selected for cooling, which can not only ensure the cooling capacity of the distribution room 4, but also save energy consumption.

[0087] According to an embodiment of the present disclosure, when the temperature of the power distribution room 4 exceeds a preset value, and after the heat exchange device 7 and the refrigeration device 3 are used to cool the power distribution room 4 at the same time, it is determined whether the temperature of the power distribution room 4 is lower than the external ambient temperature of the cabinet 1.

[0088] If the temperature of the power distribution room 4 is lower than the external environment temperature of the cabinet 1 , the heat exchange device 7 is unavailable, and the refrigeration device 3 can be used to cool the power distribution room 4 and the cabinet room 2 separately.

[0089] If the temperature of the power distribution room 4 is higher than the external environment temperature of the cabinet 1 , the heat exchange device 7 can be used at this time, and the heat exchange device 7 and the refrigeration device 3 can continue to be used to cool the power distribution room 4 at the same time.

[0090] When the temperature of the power distribution room 4 is lower than a preset value, the refrigeration equipment 3 and the heat exchange equipment 7 are stopped from sending back air.

[0091] Through the above method, the switch of the heat exchange device 7 can be reasonably adjusted according to the temperature difference between the temperature of the distribution room 4 and the external ambient temperature of the box 1. The heat exchange device 7 can be used to supply cold air to the box 1, thereby reducing the power consumption of the refrigeration equipment 3.

[0092] According to an embodiment of the present disclosure, if the temperature of the power distribution room 4 is lower than the external environment temperature of the cabinet 1, and after the power distribution room 4 is cooled by the refrigeration device 3 alone, it is determined whether the wind speed in the first air duct 5 and the second air duct 6 reaches a threshold value. The threshold value is the maximum value of the wind speed, and when the wind speed reaches the maximum value, the rotation speeds of the first fan 51, the second fan 52, the third fan 61 and the fourth fan 62 are the maximum.

[0093] If the wind speed in the first air duct 5 and the second air duct 6 reaches a threshold value, and the temperature of the distribution room 4 still exceeds a preset value, the cold air temperature of the refrigeration equipment 3 can be reduced. For example, the refrigeration power of the refrigeration equipment 3 can be increased, so that the temperature of the cold air generated by the refrigeration equipment 3 is low enough to meet the cooling demand.

[0094] If the wind speed in the first air duct 5 and the second air duct 6 does not reach the threshold, the wind speed in the first air duct 5 and the second air duct 6 can be increased, for example, by increasing the rotation speed of the first fan 51, the second fan 52, the third fan 61 and the fourth fan 62, so that the wind speed of the cold air in the first air duct 5 and the hot air in the second air duct 6 is large enough to meet the heat exchange demand.

[0095] When the temperature of the power distribution room 4 is lower than a preset value, the refrigeration equipment 3 stops supplying return air.

[0096] The following combination Figure 7The operation steps of the container machine room air supply and return method of the embodiment of the present disclosure are described in detail with Mode 1, Mode 2, Mode 3, and Mode 4, among which Mode 1, Mode 2, Mode 3, and Mode 4 have been introduced in the previous text and will not be repeated here.

[0097] Step 1: Determine whether the temperature of the distribution room 4 exceeds the preset value. When the temperature of the distribution room 4 exceeds the preset value, proceed to step 2, otherwise determine whether the external ambient temperature of the cabinet 1 is lower than the temperature of the distribution room 4 by more than 10°C (that is, the temperature difference between the external ambient temperature of the cabinet 1 and the temperature of the distribution room 4 exceeds 10°C). If the external ambient temperature of the cabinet 1 is lower than the temperature of the distribution room 4 by more than 10°C, mode 4 is used for operation, otherwise mode 1 is used for operation.

[0098] Step 2: Operate in mode 2, and then determine whether the temperature of the distribution room 4 is lower than the external ambient temperature of the cabinet 1. If the temperature of the distribution room 4 is lower than the external ambient temperature of the cabinet 1, proceed to step 3, otherwise continue to operate in mode 2.

[0099] Step three: operate in mode three. If the temperature of the distribution room 4 is still greater than the preset value, determine whether the rotation speeds of the first fan 51, the second fan 52, the third fan 61 and the fourth fan 62 have reached the maximum value. If the rotation speeds have reached the maximum value, proceed to step four; otherwise, proceed to step five.

[0100] Step 4: Lower the supply air temperature of the refrigeration equipment 3 (for example, it can be lowered according to the set value, such as lowering 1°C or 2°C each time), so that the temperature of the cold channel 21 is lowered, thereby lowering the temperature of the cold air sent into the distribution room 4 through the first air duct 5, thereby lowering the temperature of the distribution room 4, and then proceed to step 6.

[0101] Step five: Increase the rotation speeds of the first fan 51, the second fan 52, the third fan 61 and the fourth fan 62 to increase the air volume of the return air flow, thereby reducing the temperature of the power distribution room 4, and then proceed to step six.

[0102] Step 6: Determine whether the temperature of the distribution room 4 is lower than the preset value. If the temperature is lower than the preset value, end the return air supply, otherwise proceed to step 7.

[0103] Step seven: Determine whether the air supply temperature of the refrigeration equipment 3 has reached the minimum value (since the air supply temperature of the refrigeration equipment 3 cannot be continuously reduced, there will be a minimum value according to the actual situation. When the minimum value is reached, the temperature cannot be further reduced). If the air supply temperature of the refrigeration equipment 3 has reached the minimum value, it can no longer be automatically adjusted to lower the temperature of the distribution room 4. An alarm can be issued to request manual processing, otherwise return to step three.

[0104] When the temperature of the distribution room 4 is lower than the preset value, the return air supply is stopped.

[0105] The container machine room air supply and return method of the embodiment of the present disclosure can utilize the refrigeration equipment 3 and the heat exchange equipment 7 to cooperate in cooling the internal environment of the box body 1, and adjust the switch of the heat exchange equipment 7 in real time according to the temperature difference between the external environment temperature of the box body 1 and the temperature of the power distribution room 4, and utilize the heat exchange equipment 7 to exchange heat with the external environment of the box body 1 to reduce the cooling capacity of the refrigeration equipment 3 and reduce the power consumption of the refrigeration equipment 3, while ensuring that the temperature of the power distribution room 4 is lower than the preset value to prevent the temperature from being too high and affecting the safe operation of the equipment in the box body 1.
