Description

Technical Field

[0001] The embodiments of the present application relate to the field of air conditioning technology, and in particular, to a computer room air conditioner and a control method and a control device thereof. Background Art

[0002] Heat pipe energy-saving technology is widely used in the field of computer room air conditioning, but the cooling capacity of the heat pipe system is easily affected by the outdoor temperature of the computer room. The higher the outdoor temperature, the worse the cooling capacity of the heat pipe system will be. When the temperature difference between the indoor and outdoor of the computer room is too small or even negative, the heat pipe system will not be able to effectively cool. Therefore, the heat pipe system alone cannot meet the continuous cooling needs of the computer room.

[0003] In order to solve the problem that the heat pipe system cannot operate continuously throughout the year, a compression refrigeration system is usually added. According to the outdoor temperature conditions, a compression refrigeration system or a heat pipe system is selected to provide cooling for the computer room. For example, when the outdoor temperature is high (such as in summer), a conventional compression refrigeration system is used to cool the air conditioner, and when the outdoor temperature is low (such as in winter), a heat pipe system is used to cool the computer room to meet the temperature and humidity requirements of the computer room. However, this operation mode still requires the operation of a conventional compression refrigeration system to provide cooling for the computer room during transitional seasons (such as spring and autumn), and cannot maximize the use of outdoor natural cold sources, resulting in excessive energy consumption of the air conditioning system throughout the year. Summary of the invention

[0008] The controller is used to obtain the outdoor temperature of the data center computer room.

In addition, the term "comprising" and any of their variations are intended to cover non-exclusive protection. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0060] In the technical solution of this application, the collection, dissemination, and use of data are in compliance with the requirements of relevant national laws and regulations.

[0061] Before introducing a computer room air conditioner provided by an embodiment of the present application, in order to facilitate understanding, the technical background of the embodiment of the present application is first introduced in detail below.

[0062] IDC computer rooms, due to their characteristics of continuous operation throughout the year, pose severe challenges to the energy consumption and reliability of the cooling system. IDC refers to a platform with complete equipment (including high-speed Internet access bandwidth, high-performance local area network, safe and reliable computer room environment, etc.), professional management, and complete application service platform. ICT refers to a new concept and new technical field formed by the integration of information technology and communication technology. With the development of technology, these two technologies have gradually become inseparable and gradually merged into one category.

[0063] Heat pipe energy-saving technology is widely used in the field of computer room air conditioning, but the cooling capacity of the heat pipe system is easily affected by the outdoor temperature of the computer room. The higher the outdoor temperature, the worse the cooling capacity of the heat pipe system will be. When the temperature difference between the indoor and outdoor of the computer room is too small or even negative, the heat pipe system will not be able to effectively cool. Therefore, the heat pipe system alone cannot meet the continuous cooling needs of the computer room.

[0064] In order to solve the problem that the heat pipe system cannot operate continuously throughout the year, a compression refrigeration system is usually added. According to the outdoor temperature conditions, a compression refrigeration system or a heat pipe system is selected to provide cooling for the computer room. For example, when the outdoor temperature is high (such as in summer), a conventional compression refrigeration system is used to cool the air conditioner, and when the outdoor temperature is low (such as in winter), a heat pipe system is used to cool the computer room to meet the temperature and humidity requirements of the computer room. However, this operation mode still requires the operation of a conventional compression refrigeration system to provide cooling for the computer room during transitional seasons (such as spring and autumn), and cannot maximize the use of outdoor natural cold sources, resulting in excessive energy consumption of the air conditioning system throughout the year.

[0065] In order to solve the above problems, the present application proposes a computer room air conditioner and a control method and a control device thereof, so as to make full use of outdoor natural cold sources in transition seasons and reduce the energy consumption of the computer room air conditioning system throughout the year.

[0066] Reference below Figure 1 The structural diagram of a computer room air conditioner is shown to illustrate the technical solution provided by the embodiment of the present application. Figure 1 As shown, the computer room air conditioner includes: a heat pipe natural cooling circuit, a cooling tower natural cooling circuit and a controller 100;

[0067] The heat pipe natural cooling circuit includes a circuit consisting of a first evaporator 101, a first electric valve 109, a condenser 103 and a second electric valve 110 connected in sequence;

[0068] The cooling tower natural cooling circuit includes a circuit consisting of a second evaporator 102, a third electric valve 119, a cooling tower 106, a cooling water pump 107 and a fourth electric valve 120 connected in sequence;

[0069] The controller 100 is used to obtain the outdoor temperature of the data center computer room. If the outdoor temperature is greater than a set first temperature threshold and less than a set second temperature threshold, the first electric valve 109, the second electric valve 110, the third electric valve 119 and the fourth electric valve 120 are controlled to be in an open state to utilize the heat pipe natural cooling circuit and the cooling tower natural cooling circuit to cool the data center computer room, wherein the first temperature threshold is less than the second temperature threshold.

[0070] The first temperature threshold and the second temperature threshold can be set according to actual conditions. The condenser 103 includes a module heat pipe host 1031 and a condensing fan 103. The controller 100 obtains the outdoor temperature detected by a temperature sensor placed outside the data center computer room. The first evaporator 101 can also be called a natural cold source fluorine coil, and the second evaporator 102 can also be called a chilled water coil. The computer room air conditioner includes N outdoor units, where N is a positive integer greater than 0.

[0071] Since the indoor unit of a traditional computer room air conditioner is usually equipped with only one set of cooling coils, in order to improve the reliability of the computer room air conditioner refrigeration, the indoor unit generally adopts an N+1 or 2N backup method, which not only increases the initial investment in the computer room air conditioner, but also occupies the cabinet space of the data center computer room, reducing the space utilization rate of the data center computer room.

[0072] In order to solve the above problems, each indoor unit of the computer room air conditioner in the embodiment of the present application includes a first evaporator and a second evaporator. Figure 2 A schematic diagram of the structure of an indoor unit of a computer room air conditioner provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the first evaporator 101 and the second evaporator 102 are stacked front and back and share the same set of cooling fans. The airflow direction is from left to right, and the airflow passes through the first evaporator 101 first and then through the second evaporator 102.

[0073] In an embodiment of the present application, a first evaporator and a second evaporator are provided in each indoor unit to improve the reliability and redundancy of the operation of the computer room air conditioner, reduce the space occupied by the data center computer room, and improve the space utilization rate of the data center computer room.

[0074] In the embodiment of the present application, Figure 3 A schematic diagram of a heat pipe natural cooling circuit and a cooling tower natural cooling circuit provided in an embodiment of the present application is shown in FIG. Figure 3As shown, when the outdoor temperature is greater than the first temperature threshold and less than the second temperature threshold, it indicates that the current season is transitional, i.e., spring or autumn, and the condenser 103 starts working, but the cooling capacity is reduced and cannot fully meet the cooling demand of the computer room. At this time, the cooling tower 106 needs to provide part of the cooling capacity, i.e., the condenser 103 and the cooling tower 106 work at the same time to meet the cooling demand of the computer room. Therefore, the controller 100 controls the first electric valve 109, the second electric valve 110, the third electric valve 119 and the fourth electric valve 120 to be in an open state, and controls the fifth electric valve 111, the sixth electric valve 112, the seventh electric valve 113, the eighth electric valve 114, the ninth electric valve 115, the tenth electric valve 116, the eleventh electric valve 117 and the twelfth electric valve 118 to be in a closed state, so as to use the heat pipe natural cooling circuit and the cooling tower natural cooling circuit to cool the data center computer room.

[0075] In the process of cooling the data center computer room by using the heat pipe natural cooling loop and the cooling tower natural cooling loop, the low-temperature cooling water in the cooling tower 106 enters the second evaporator 102 through the cooling water pump 107 and the fourth electric valve 120 in turn; after the low-temperature cooling water absorbs part of the heat generated by the electronic equipment in the data center, it enters the cooling tower 106 through the third electric valve 119 to dissipate heat to the atmosphere, generating low-temperature cooling water, and re-enters the second evaporator 102 to absorb heat. At the same time, the refrigerant in the first evaporator 101 absorbs part of the heat generated by the electronic equipment in the data center and turns into refrigerant vapor; under the action of the height difference between the indoor and outdoor units, the refrigeration machine vapor enters the module heat pipe host 1031 through the first electric valve 109, condenses into liquid under the action of the condensing fan 1032, and re-enters the first evaporator 101 through the second electric valve 110 to absorb heat.

[0076] In an embodiment of the present application, the computer room air conditioner includes a heat pipe natural cooling circuit, a cooling tower natural cooling circuit and a controller. The heat pipe natural cooling circuit includes a circuit consisting of a first evaporator, a first electric valve, a condenser and a second electric valve connected in sequence, and the cooling tower natural cooling circuit includes a circuit consisting of a second evaporator, a third electric valve, a cooling tower, a cooling water pump and a fourth electric valve connected in sequence. The controller is used to compare the obtained outdoor temperature of the data center computer room with the set first temperature threshold and the set second temperature threshold respectively to determine the current season. If the outdoor temperature is greater than the first temperature threshold and less than the second temperature threshold, it indicates that the current season is in transition, that is, spring or autumn, then the first electric valve, the second electric valve, the third electric valve and the fourth electric valve are all controlled to be in an open state, so as to use the heat pipe natural cooling circuit and the cooling tower natural cooling circuit to cool the data center computer room, that is, the first evaporator and the second evaporator are enabled to work at the same time, increase the heat exchange area of ​​the evaporator, increase the cooling capacity, and realize that the outdoor natural cold source can be fully utilized in the transition season, reduce the energy consumption of the air conditioning system throughout the year, and improve the efficiency of the air conditioning system throughout the year.

[0077] Optionally, the controller is further configured to:

[0078] If the outdoor temperature is less than or equal to the first temperature threshold, the first electric valve 109 and the second electric valve 110 are controlled to be in an open state to utilize the heat pipe natural cooling circuit to cool the data center room, or the third electric valve 119 and the fourth electric valve 120 are controlled to be in an open state to utilize the cooling tower natural cooling circuit to cool the data center room.

[0079] In the embodiment of the present application, Figure 4 A schematic diagram of a heat pipe natural cooling circuit provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, when the outdoor temperature is less than or equal to the first temperature threshold, it indicates that it is winter and the outdoor temperature is low, and the condenser 103 starts working to meet the cooling demand of the computer room. Therefore, the controller 100 controls the first electric valve 109 and the second electric valve 110 to be in an open state, and controls the third electric valve 119, the fourth electric valve 120, the fifth electric valve 111, the sixth electric valve 112, the seventh electric valve 113, the eighth electric valve 114, the ninth electric valve 115, the tenth electric valve 116, the eleventh electric valve 117 and the twelfth electric valve 118 to be in a closed state, so as to use the heat pipe natural cooling loop to cool the data center computer room.

[0080] In the process of cooling the data center computer room using the heat pipe natural cooling loop, the refrigerant inside the first evaporator 101 absorbs part of the heat generated by the electronic equipment in the data center and turns into refrigerant vapor; under the action of the height difference between the indoor and outdoor units, the refrigeration machine vapor enters the module heat pipe host 1031 through the first electric valve 109, is condensed into liquid under the action of the condensing fan 1032, and re-enters the first evaporator 101 through the second electric valve 110 to absorb heat.

[0081] In the embodiment of the present application, Figure 5 A schematic diagram of a natural cooling circuit of a cooling tower provided in an embodiment of the present application, such as Figure 5 As shown, when the outdoor temperature is less than or equal to the first temperature threshold, it indicates that it is winter and the outdoor temperature is low, and the cooling tower 103 starts working to meet the cooling demand of the computer room. Therefore, the controller 100 controls the third electric valve 119 and the fourth electric valve 120 to be in an open state, and controls the first electric valve 109, the second electric valve 110, the third electric valve 119, the fourth electric valve 120, the fifth electric valve 111, the sixth electric valve 112, the seventh electric valve 113, the eighth electric valve 114, the ninth electric valve 115, the tenth electric valve 116, the eleventh electric valve 117 and the twelfth electric valve 118 to be in a closed state, so as to use the natural cooling circuit of the cooling tower to cool the data center computer room.

[0082] In the process of cooling the data center room by using the natural cooling circuit of the cooling tower, the low-temperature cooling water in the cooling tower 106 enters the second evaporator 102 through the cooling water pump 107 and the fourth electric valve 120 in turn; after the low-temperature cooling water absorbs part of the heat generated by the electronic equipment in the data center, it enters the cooling tower 106 through the third electric valve 119 to dissipate heat to the atmosphere, generating low-temperature cooling water, and re-enters the second evaporator 102 to absorb heat.

[0083] In the embodiment of the present application, under low temperature conditions in winter, the heat pipe natural cooling circuit and the cooling tower natural cooling circuit back up each other to improve the reliability and redundancy of the refrigeration system of the computer room air conditioner. Usually, the heat pipe natural cooling circuit is used first to cool the data center computer room. When the heat pipe natural cooling circuit needs maintenance or fails, the cooling tower natural cooling circuit is used to cool the data center computer room.

[0084] Optionally, the computer room air conditioner further comprises a heat exchanger cooling circuit;

[0085] The heat exchanger cooling circuit includes a circuit consisting of a first evaporator 101, a fifth electric valve 111, a water / fluorine heat exchanger 104, a sixth electric valve 112, a chiller 105, a seventh electric valve 113, a cooling tower 106, a cooling water pump 107, an eighth electric valve 114, a chilled water pump 108, a ninth electric valve 115 and a tenth electric valve 116 connected in sequence;

[0086] The controller 100 is also used for:

[0087] If the outdoor temperature is greater than or equal to the second temperature threshold, the fifth electric valve 111, the sixth electric valve 112, the seventh electric valve 113, the eighth electric valve 114, the ninth electric valve 115 and the tenth electric valve 116 are all controlled to be in an open state to utilize the heat exchanger cooling circuit to cool the data center room.

[0088] In the embodiment of the present application, Figure 6 A schematic diagram of a heat exchanger cooling circuit provided in an embodiment of the present application, such as Figure 6 As shown, when the outdoor temperature is greater than or equal to the second temperature threshold, it indicates that it is summer and the outdoor temperature is high. The condenser 103 cannot start working normally. Therefore, the water / fluorine heat exchanger 104, the chiller 105 and the cooling tower 106 are started, and the water / fluorine heat exchanger 104 provides a cold source for the first evaporator 101, thereby meeting the cooling demand of the data center computer room. Therefore, the controller 100 controls the fifth electric valve 111, the sixth electric valve 112, the seventh electric valve 113, the eighth electric valve 114, the ninth electric valve 115 and the tenth electric valve 116 to be in an open state, and controls the first electric valve 109, the second electric valve 110, the third electric valve 119 and the fourth electric valve 120, the eleventh electric valve 117 and the twelfth electric valve 118 to be in a closed state, so as to use the heat exchanger cooling circuit to cool the data center computer room.

[0089] In the process of cooling the data center room by using the heat exchanger cooling loop, the refrigerant inside the first evaporator 101 absorbs the heat generated by the electronic equipment in the data center room and turns into refrigerant vapor; the refrigeration machine vapor enters the water / fluorine heat exchanger 104 through the fifth electric valve 111, and exchanges heat with the low-temperature chilled water provided by the chiller 105 in the water / fluorine heat exchanger 104, and the refrigerant vapor is condensed into liquid and then re-enters the first evaporator 101 through the tenth electric valve 116 to absorb heat. The low-temperature chilled water absorbs the heat of the refrigerant vapor and the temperature rises to obtain high-temperature chilled water. The high-temperature chilled water passes through the sixth electric valve, the chiller 105, the seventh electric valve 113 and the cooling tower 106 in sequence, thereby dissipating the heat of the high-temperature chilled water into the atmosphere to obtain low-temperature chilled water, and the low-temperature chilled water passes through the cooling water pump 107, the eighth electric valve 114, the chiller 105, the chilled water pump 108 and the ninth electric valve 115 in sequence to re-enter the water / fluorine heat exchanger 104.

[0090] Optionally, the computer room air conditioner also includes a conventional mechanical compression cooling circuit;

[0091] The conventional mechanical compression cooling circuit includes a circuit consisting of a second evaporator 102, an eleventh electric valve 117, a chiller 105, a seventh electric valve 113, a cooling tower 106, a cooling water pump 107, an eighth electric valve 114, a chilled water pump 108 and a twelfth electric valve 118 connected in sequence;

[0092] The controller 100 is also used for:

[0093] If the outdoor temperature is greater than or equal to the second temperature threshold, the seventh electric valve 113, the eighth electric valve 114, the eleventh electric valve 117 and the twelfth electric valve 118 are all controlled to be in an open state to cool the data center room using a conventional mechanical compression cooling circuit.

[0094] In the embodiment of the present application, Figure 7 A schematic diagram of a conventional mechanical compression cooling circuit provided in an embodiment of the present application is shown in FIG. Figure 7As shown, when the outdoor temperature is greater than or equal to the second temperature threshold, it indicates that it is currently in summer. The chilled water produced by the chiller 105 can not only provide a cold source for the first evaporator through the water / fluorine heat exchanger 104, but also directly enter the second evaporator to directly provide cold capacity for the data center room. This mode is the traditional compression refrigeration mode. That is, the chiller 105 and the cooling tower 106 are started to meet the cooling needs of the data center room. Therefore, the controller 100 controls the seventh electric valve 113, the eighth electric valve 114, the eleventh electric valve 117 and the twelfth electric valve 118 to be in an open state, and controls the first electric valve 109, the second electric valve 110, the third electric valve 119 and the fourth electric valve 120, the fifth electric valve 111, the sixth electric valve 112, the ninth electric valve 115 and the tenth electric valve 116 to be in a closed state, so as to use a conventional mechanical compression cooling circuit to cool the data center room.

[0095] In the process of cooling the data center room using a conventional mechanical compression cooling circuit, the low-temperature chilled water inside the second evaporator 102 absorbs the heat generated by the electronic equipment in the data center room and becomes high-temperature chilled water. The heat of the high-temperature chilled water is dissipated into the atmosphere through the eleventh electric valve 117, the seventh electric valve 113 and the cooling tower 106 to obtain low-temperature chilled water. The low-temperature chilled water then re-enters the second steam engine 102 through the cooling water pump 107, the eighth electric valve 114, the chilled water main unit 105, the chilled water pump 108 and the twelfth electric valve 118 in sequence.

[0096] In the embodiment of the present application, under high temperature conditions in summer, the heat exchanger cooling circuit and the conventional mechanical compression cooling circuit back up each other to improve the reliability and redundancy of the refrigeration system of the computer room air conditioner. Usually, the conventional mechanical compression cooling circuit is used first to cool the data center computer room. When the conventional mechanical compression cooling circuit needs maintenance or fails, the heat exchanger cooling circuit is used to cool the data center computer room.

[0097] In particular, in transitional seasons, depending on the actual outdoor temperature characteristics, there may be a situation where the heat pipe natural cooling loop and the cooling tower natural cooling loop working simultaneously still cannot meet the cooling demand of the computer room. Therefore, the controller 100 in the present application is also used for:

[0098] If the outdoor temperature is greater than the first temperature threshold and less than the set third temperature threshold, the first electric valve 109, the second electric valve 110, the third electric valve 119 and the fourth electric valve 120 are all controlled to be in an open state, so as to utilize the heat pipe natural cooling circuit and the cooling tower natural cooling circuit to cool the data center room, wherein the third temperature threshold is greater than the first temperature threshold and less than the second temperature threshold;

[0099] If the outdoor temperature is greater than or equal to the third temperature threshold and less than the second temperature threshold, the seventh electric valve 113, the eighth electric valve 114, the eleventh electric valve 117 and the twelfth electric valve 118 are all controlled to be in an open state to cool the data center room using a conventional mechanical compression cooling circuit.

[0100] In the present application embodiment, Figure 3 As shown, when the outdoor temperature is greater than the first temperature threshold and less than the set third temperature threshold, it indicates that the condenser 103 and the cooling tower 106 work simultaneously and can meet the cooling demand of the computer room. Therefore, the controller 100 controls the first electric valve 109, the second electric valve 110, the third electric valve 119 and the fourth electric valve 120 to be in an open state, and controls the fifth electric valve 111, the sixth electric valve 112, the seventh electric valve 113, the eighth electric valve 114, the ninth electric valve 115, the tenth electric valve 116, the eleventh electric valve 117 and the twelfth electric valve 118 to be in a closed state, so as to utilize the heat pipe natural cooling circuit and the cooling tower natural cooling circuit to cool the data center computer room.

[0101] When the outdoor temperature is greater than or equal to the third temperature threshold and less than the second temperature threshold, it indicates that the condenser 103 and the cooling tower 106 work simultaneously and cannot meet the cooling demand of the computer room. Therefore, the controller 100 controls the seventh electric valve 113, the eighth electric valve 114, the eleventh electric valve 117 and the twelfth electric valve 118 to be in an open state, and controls the first electric valve 109, the second electric valve 110, the third electric valve 119 and the fourth electric valve 120, the fifth electric valve 111, the sixth electric valve 112, the ninth electric valve 115 and the tenth electric valve 116 to be in a closed state, so as to cool the data center computer room using a conventional mechanical compression cooling circuit.

[0102] The specific steps of the computer room air conditioning control method provided above are described in detail below. Figure 8 As shown:

[0103] Step 801, obtaining the outdoor temperature of the data center room;

[0104] Step 802, if the outdoor temperature is greater than the set first temperature threshold and less than the set second temperature threshold, the first electric valve, the second electric valve, the third electric valve and the fourth electric valve are all controlled to be in an open state to utilize the heat pipe natural cooling circuit and the cooling tower natural cooling circuit to cool the data center room.

[0105] The first temperature threshold is smaller than the second temperature threshold, and the first temperature threshold and the second temperature threshold can be set according to actual conditions.

[0106] Specifically, Figure 3As shown, if the outdoor temperature is greater than the set first temperature threshold and less than the set second temperature threshold, the first electric valve 109, the second electric valve 110, the third electric valve 119 and the fourth electric valve 120 are all controlled to be in an open state, and the fifth electric valve 111, the sixth electric valve 112, the seventh electric valve 113, the eighth electric valve 114, the ninth electric valve 115, the tenth electric valve 116, the eleventh electric valve 117 and the twelfth electric valve 118 are all controlled to be in a closed state, so as to utilize the heat pipe natural cooling circuit and the cooling tower natural cooling circuit to cool the data center computer room.

[0107] In the embodiment of the present application, after obtaining the outdoor temperature of the data center room, if the outdoor temperature is less than or equal to the first temperature threshold, it indicates that it is currently winter, and the data center room can be cooled by the following two methods:

[0108] The first method controls the first electric valve and the second electric valve to be in an open state, so as to utilize a heat pipe natural cooling loop to cool the data center room.

[0109] Specifically, Figure 4 As shown, when the outdoor temperature is less than or equal to the first temperature threshold, the first electric valve 109 and the second electric valve 110 are controlled to be in an open state, and the third electric valve 119, the fourth electric valve 120, the fifth electric valve 111, the sixth electric valve 112, the seventh electric valve 113, the eighth electric valve 114, the ninth electric valve 115, the tenth electric valve 116, the eleventh electric valve 117 and the twelfth electric valve 118 are controlled to be in a closed state, so as to utilize the heat pipe natural cooling circuit to cool the data center room.

[0110] The second method is to control the third electric valve and the fourth electric valve to be in an open state, so as to utilize the natural cooling circuit of the cooling tower to cool the data center room.

[0111] Specifically, Figure 5 As shown, when the outdoor temperature is less than or equal to the first temperature threshold, the third electric valve 119 and the fourth electric valve 120 are both controlled to be in an open state, and the first electric valve 109, the second electric valve 110, the third electric valve 119, the fourth electric valve 120, the fifth electric valve 111, the sixth electric valve 112, the seventh electric valve 113, the eighth electric valve 114, the ninth electric valve 115, the tenth electric valve 116, the eleventh electric valve 117 and the twelfth electric valve 118 are all controlled to be in a closed state, so as to utilize the natural cooling circuit of the cooling tower to cool the data center room.

[0112] In the embodiment of the present application, under low temperature conditions in winter, the heat pipe natural cooling circuit can be used preferentially to cool the data center room. When the heat pipe natural cooling circuit needs maintenance or fails, the cooling tower natural cooling circuit can be used to cool the data center room. The cooling tower natural cooling circuit can also be used preferentially to cool the data center room. When the cooling tower natural cooling circuit needs maintenance or fails, the heat pipe natural cooling circuit can be used to cool the data center room.

[0113] In the embodiment of the present application, after obtaining the outdoor temperature of the data center room, if the outdoor temperature is greater than or equal to the second temperature threshold, it indicates that it is currently summer, and the data center room can be cooled by the following two methods:

[0114] The first method controls the fifth electric valve, the sixth electric valve, the seventh electric valve, the eighth electric valve, the ninth electric valve and the tenth electric valve to be in an open state, so as to utilize the heat exchanger cooling circuit to cool the data center computer room.

[0115] Specifically, Figure 6 As shown, when the outdoor temperature is greater than or equal to the second temperature threshold, the fifth electric valve 111, the sixth electric valve 112, the seventh electric valve 113, the eighth electric valve 114, the ninth electric valve 115 and the tenth electric valve 116 are all controlled to be in an open state, and the first electric valve 109, the second electric valve 110, the third electric valve 119 and the fourth electric valve 120, the eleventh electric valve 117 and the twelfth electric valve 118 are all controlled to be in a closed state, so as to utilize the heat exchanger cooling circuit to cool the data center room.

[0116] The second method is to control the seventh electric valve, the eighth electric valve, the eleventh electric valve and the twelfth electric valve to be in an open state, so as to cool the data center room by using a conventional mechanical compression cooling circuit.

[0117] Specifically, Figure 7 As shown, when the outdoor temperature is greater than or equal to the second temperature threshold, the seventh electric valve 113, the eighth electric valve 114, the eleventh electric valve 117 and the twelfth electric valve 118 are all controlled to be in an open state, and the first electric valve 109, the second electric valve 110, the third electric valve 119 and the fourth electric valve 120, the fifth electric valve 111, the sixth electric valve 112, the ninth electric valve 115 and the tenth electric valve 116 are all controlled to be in a closed state, so as to utilize a conventional mechanical compression cooling circuit to cool the data center room.

[0118] In the embodiment of the present application, under high temperature conditions in summer, the conventional mechanical compression cooling circuit can be used preferentially to cool the data center room. When the conventional mechanical compression cooling circuit needs maintenance or fails, the heat exchanger cooling circuit is used to cool the data center room. The heat exchanger cooling circuit can also be used preferentially to cool the data center room. When the heat exchanger cooling circuit needs maintenance or fails, the conventional mechanical compression cooling circuit is used to cool the data center room.

[0119] In particular, in the transition season, depending on the actual outdoor temperature characteristics, there may be a situation where the heat pipe natural cooling loop and the cooling tower natural cooling loop working at the same time still cannot meet the cooling needs of the computer room. Therefore, after obtaining the outdoor temperature of the data center computer room, this application is divided into the following two situations:

[0120] In the first case, if the outdoor temperature is greater than the first temperature threshold and less than the set third temperature threshold, the first electric valve, the second electric valve, the third electric valve and the fourth electric valve are all controlled to be in an open state to utilize the heat pipe natural cooling circuit and the cooling tower natural cooling circuit to cool the data center room.

[0121] The third temperature threshold is greater than the first temperature threshold and less than the second temperature threshold. The third temperature threshold can be set according to actual conditions.

[0122] Specifically, Figure 3 As shown, when the outdoor temperature is greater than the first temperature threshold and less than the set third temperature threshold, it indicates that the condenser 103 and the cooling tower 106 work simultaneously and can meet the cooling load demand of the computer room. Therefore, the first electric valve 109, the second electric valve 110, the third electric valve 119 and the fourth electric valve 120 are all controlled to be in an open state, and the fifth electric valve 111, the sixth electric valve 112, the seventh electric valve 113, the eighth electric valve 114, the ninth electric valve 115, the tenth electric valve 116, the eleventh electric valve 117 and the twelfth electric valve 118 are all controlled to be in a closed state, so as to utilize the heat pipe natural cooling circuit and the cooling tower natural cooling circuit to cool the data center computer room.

[0123] In the second case, if the outdoor temperature is greater than or equal to the third temperature threshold and less than the second temperature threshold, the seventh electric valve, the eighth electric valve, the eleventh electric valve and the twelfth electric valve are all controlled to be in an open state to use a conventional mechanical compression cooling circuit to cool the data center room.

[0124] Specifically, when the outdoor temperature is greater than or equal to the third temperature threshold and less than the second temperature threshold, it indicates that the condenser 103 and the cooling tower 106 work simultaneously and cannot meet the cooling load demand of the computer room. Therefore, the seventh electric valve 113, the eighth electric valve 114, the eleventh electric valve 117 and the twelfth electric valve 118 are all controlled to be in an open state, and the first electric valve 109, the second electric valve 110, the third electric valve 119 and the fourth electric valve 120, the fifth electric valve 111, the sixth electric valve 112, the ninth electric valve 115 and the tenth electric valve 116 are all controlled to be in a closed state, so as to cool the data center computer room using a conventional mechanical compression cooling circuit.

[0125] For example, in winter, the natural cooling loop of heat pipes is used first, and in summer, the conventional mechanical compression cooling loop is used first to cool the computer room of the data center.

[0128] Step 903, control the first electric valve and the second electric valve to be in an open state, so as to utilize the heat pipe natural cooling loop to cool the data center room.

[0129] Step 904, determine whether the heat pipe natural cooling circuit fails or needs maintenance, if so, execute step 905, otherwise, execute step 906.

[0130] Step 905, control the third electric valve and the fourth electric valve to be in an open state, so as to utilize the natural cooling circuit of the cooling tower to cool the data center room.

[0131] Step 906, keep the first electric valve and the second electric valve both in an open state to utilize the heat pipe natural cooling loop to cool the data center room.

[0132] Step 907, determine whether the outdoor temperature satisfies a second temperature threshold, if so, execute step 908, otherwise execute step 909.

[0133] Step 908, control the first electric valve, the second electric valve, the third electric valve and the fourth electric valve to be in an open state, so as to utilize the heat pipe natural cooling loop and the cooling tower natural cooling loop to cool the data center room.

[0134] Step 909 , control the seventh electric valve, the eighth electric valve, the eleventh electric valve and the twelfth electric valve to be in an open state, so as to cool the data center room by using a conventional mechanical compression cooling circuit.

[0135] Step 910, determining whether the conventional mechanical compression cooling circuit fails or is undergoing maintenance, if so, executing step 911, otherwise executing step 912.

[0136] Step 911, control the fifth electric valve, the sixth electric valve, the seventh electric valve, the eighth electric valve, the ninth electric valve and the tenth electric valve to be in an open state, so as to utilize the heat exchanger cooling circuit to cool the data center room.
