Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of temperature control equipment, in particular to a temperature control system, a control method and device, and a storage medium. BACKGROUND

[0002] Machine room temperature control system requires refrigeration throughout the year and uninterrupted operation for 24 hours a day. With the continuous deepening of network application in production and life as well as industry, the server installation quantity presents explosive growth, which also brings huge heat dissipation demand, and the energy efficiency of precision temperature control system is paid more and more attention. The market of high energy efficiency means low carbon and economy.

[0003] Since the fluorine pump double-cycle temperature control system can use the fluorine pump to replace the compressor to drive the refrigerant circulation for natural cooling when the ambient temperature is low, it has an innate installation advantage in the energy-saving reconstruction of data centers, and has an energy efficiency advantage, so that its proportion in the precision temperature control system gradually increases. At present, in the fluorine pump double-cycle temperature control system, the condenser is a wind-cooled finned condenser, and the condenser inlet air temperature is positively correlated with the system condensing temperature. As long as the condenser inlet air temperature is reduced, the condensing temperature can be reduced, and the reduction of the condensing temperature means the reduction of the power consumption when the compressor is running and the early cut-in of natural cooling, thereby shortening the running time of the compressor.

[0004] In related technologies, the condensing temperature can be reduced by increasing the heat exchange area of the condenser, increasing the heat dissipation air volume, etc., but the cost of this scheme is high and the efficiency is low. SUMMARY

[0076] Figure 1 A schematic diagram of a temperature control system 100 is shown. The temperature control system 100 comprises a wet film 101, a water delivery pipeline 106, a fan 103, a condenser 102, a compressor 104, a throttling mechanism 127 and an evaporator 105.

[0077] As Figure 2As shown, the air inlet face 109 of the wet membrane 101 intersects the air inlet direction of the fan 103;

[0078] The air inlet face 111 of the condenser 102 intersects the air inlet direction of the fan 103;

[0079] The air outlet face 110 of the wet membrane 101 is adjacent to the air inlet face 111 of the condenser 102;

[0080] The water outlet 107 of the water supply pipeline 106 is directed to the water inlet face 113 of the wet membrane 101;

[0081] The condenser 102, the compressor 104, the throttling mechanism 127 and the evaporator 105 are connected to form a temperature control device (for example, an air conditioning device).

[0082] The wet membrane 101 can be a high-molecular composite material formed by sintering a plant fiber-based substrate treated with resin into a corrugated plate shape. The wet membrane 101 has the characteristics of strong water absorption, excellent self-cleaning ability, non-toxicity, acid and alkali resistance, mold resistance, and flame resistance. The corrugated plate structure of the wet membrane 101 can provide the maximum contact area between air and its surface, and the flow channel angle of the membrane body is 45 degrees. When hot air passes through the wet membrane 101, water (i.e., cooling liquid) fully absorbs the heat of the air to vaporize and evaporate, thereby achieving the purpose of cooling the air.

[0083] Optionally, the wet membrane 101 can use a drop-in soaking liquid supply mode. The filtered water (i.e., cooling liquid) is sent to the water outlet 107 (which can be a water shower or a sprayer) at the top of the wet membrane 101 through the water supply pipeline 106. Under the action of gravity, the water penetrates downward along the surface of the wet membrane 101 and is fully absorbed by the wet membrane 101. Due to the excellent water absorption of the wet membrane 101, a uniform water film is formed. When air passes through, the water evaporates and absorbs heat, reducing the temperature of the air.

[0084] The water supply pipeline 106 is used to supply cooling liquid to the wet membrane 101. The water supply pipeline 106 connects the water tank 108 and the wet membrane 101 to spray the cooling liquid in the water tank 108 onto the wet membrane 101.

[0085] Optionally, the water supply pipeline 106 has a water outlet 107, which can be directed to the water inlet face 113 of the wet membrane 101. The water outlet 107 can be connected to a water shower or a sprayer to uniformly spray the cooling liquid (for example, water) to the water inlet face 113 of the wet membrane 101. The water inlet face 113 of the wet membrane 101 can be the upper top surface of the wet membrane 101, and the cooling liquid penetrates the entire wet membrane 101 under the action of gravity. Of course, the water inlet face 113 of the wet membrane 101 can also be the side surface of the wet membrane 101.

[0086] Optionally, as shown in FIG. 2, the water supply pipeline 106 has a water outlet 107, which is directed to the water inlet face 113 of the wet membrane 101. The water outlet 107 can be connected to a water shower or a sprayer to uniformly spray the cooling liquid (for example, water) to the water inlet face 113 of the wet membrane 101. The water inlet face 113 of the wet membrane 101 can be the upper top surface of the wet membrane 101, and the cooling liquid penetrates the entire wet membrane 101 under the action of gravity. Of course, the water inlet face 113 of the wet membrane 101 can also be the side surface of the wet membrane 101. Figure 2As shown, the air inlet face 109 of the wet film 101, the air outlet face 110 of the wet film 101, and the air inlet face 111 of the condenser 102 can all be perpendicular to the air inlet direction of the fan 103, so that outdoor air first passes through the wet film 101 and then enters the condenser 102.

[0087] The fan 103 is used to promote air flow, so that air passes through the condenser 102, reduces the temperature of the condenser 102, and promotes cooling of the refrigerant in the condenser 102. Optionally, the position of the fan 103 can be arbitrary, such as Figure 2 As shown in FIG. 1, the fan 103, the wet film 101, and the condenser 102 can be arranged in this order along the air inlet direction of the fan 103; the fan 103, the wet film 101, and the condenser 102 can be arranged in this order along the air inlet direction of the fan 103; or the fan 103, the wet film 101, and the condenser 102 can be arranged in this order along the air inlet direction of the fan 103.

[0088] The condenser 102, the compressor 104, the throttling mechanism 127, and the evaporator 105 constitute a temperature control device, such as an air conditioner. The refrigerant in the condenser 102 circulates between the condenser 102, the compressor 104, the throttling mechanism 127, and the evaporator 105 to regulate the indoor temperature.

[0089] The compressor 104 is the heart of the temperature control device and plays a qualitative role in the performance of the unit. It is responsible for compressing the refrigerant into high-pressure gas and driving the refrigeration cycle. The condenser 102 is a heat exchange device that cools the high-temperature and high-pressure gaseous refrigerant discharged by the compressor into liquid refrigerant, while dissipating heat to the outdoors. The throttling mechanism 127 (or "expansion valve") functions as a pressure-reducing throttle to regulate the flow of refrigerant into the evaporator 105, allowing the refrigerant to fully evaporate and absorb heat in the evaporator 105. The evaporator 105 is used to absorb indoor heat, causing the liquid refrigerant to evaporate into gas, thereby reducing the indoor temperature. The condenser 102, the compressor 104, the throttling mechanism 127, and the evaporator 105 work together to complete the refrigeration cycle of the temperature control device and achieve the purpose of reducing the indoor temperature.

[0090] In the temperature control device, the condenser 102 and the compressor 104 are located in the outdoor unit, and the evaporator 105 is located in the indoor unit. The throttling mechanism 127 can be located in the outdoor unit or in the indoor unit.

[0091] The devices in the temperature control system provided by the embodiments of the present application, except the evaporator 105 and the control assembly 2300, can be arranged in the outdoor unit. The control assembly 2300 can be arranged in the outdoor unit, or in the indoor unit, or be an independent device independent of the temperature control system. For example, the control assembly 2300 can be wirelessly connected with the sensors, the water pump 114, the water injection valve 119, the water discharge valve 120 and the like in the temperature control system, receive the sensing signals reported by the sensors through the wireless connection, and remotely control the water pump 114, the water injection valve 119, the water discharge valve 120 and the like through the wireless connection.

[0092] In summary, the temperature control system provided by the embodiments of the present application is provided with the wet membrane 101 in front of the air inlet face 111 of the condenser 102, and the condenser liquid is delivered to the wet membrane 101 through the water delivery pipeline 106. The outdoor air first passes through the wet membrane 101 and then passes through the condenser 102. The condenser liquid in the wet membrane 101 can reduce the temperature of the outdoor air through vaporization and heat absorption, and thus the temperature of the air entering the condenser 102 is reduced, and the condensing efficiency of the condenser 102 is improved.

[0093] In an alternative embodiment, based on the embodiments shown in Figure 1 and Figure 2 As shown in Figure 3 , the temperature control system further comprises a water tank 108; the water delivery pipeline 106 is provided with a water pump 114;

[0094] The water delivery pipeline 106 is used to extract the cooling liquid in the water tank 108 through the water pump 114;

[0095] The water tank 108 is provided with an opening 115 above the water tank 108;

[0096] The wet membrane 101 is located above the opening 115, and the water tank 108 is used to collect the cooling liquid flowing out of the wet membrane 101 through the opening 115.

[0097] For example, the water tank 108 can be an open-top container. For example, the water tank 108 can be a barrel-shaped container. The wet membrane 101 is prevented from being above the opening 115 of the water tank 108, so that the condenser liquid permeated out of the wet membrane 101 can naturally fall into the water tank 108. Alternatively, the vertical projection area of the opening 115 of the water tank 108 on the horizontal plane is not less than the vertical projection area of the water outlet surface (for example, the lower surface) of the wet membrane 101 on the horizontal plane.

[0098] In an alternative embodiment, the temperature control system further comprises a water tank 108; the water tank 108 is connected with at least one of the water injection pipeline 116, the water discharge pipeline 117 and the overflow pipeline 118;

[0099] The water injection pipeline 116 is provided with a water injection valve 119;

[0100] The water draining pipe 117 is provided with a water draining valve 120.

[0101] The water tank 108 comprises a water filling port, a water draining port and an overflow port, and the overflow port is higher than the water draining port.

[0102] The water filling pipe 116 is connected to the water filling port of the water tank 108.

[0103] The water draining pipe 117 is connected to the water draining port of the water tank 108.

[0104] The overflow pipe 118 is connected to the overflow port of the water tank 108.

[0105] For example, as shown in FIG. 1, the water filling valve 119 can comprise a set of water filling electric ball valves and water filling manual ball valves. Figure 3 The water filling electric ball valves and the water filling manual ball valves are connected in parallel in the water filling pipe 116, and water can be filled into the water tank 108 as long as any one of the two valves (the water filling electric ball valves and the water filling manual ball valves) is opened, and the water filling can be stopped when both valves are closed.

[0106] Similarly, as shown in FIG. 1, the water draining valve 120 can comprise a set of water draining electric ball valves and water draining manual ball valves. Figure 3 The water draining electric ball valves and the water draining manual ball valves are connected in parallel in the water draining pipe 117, and water in the water tank 108 can be drained as long as any one of the two valves (the water draining electric ball valves and the water draining manual ball valves) is opened, and the water draining can be stopped when both valves are closed.

[0107] Optionally, the water filling valve 119 can be replaced by a water filling pump, and the water filling and stopping of the water filling pipe 116 can be controlled by the water filling pump, and the water filling efficiency can be improved by the water filling pump. Similarly, the water draining valve 120 can also be replaced by a water draining pump, and the water draining and stopping of the water draining pipe 117 can be controlled by the water draining pump, and the water draining efficiency can be improved by the water draining pump.

[0108] Optionally, the water filling port of the water tank 108 can be arranged at any position of the water tank, for example, at the top area of the side of the water tank 108. The water draining port of the water tank 108 can be arranged at the bottom area of the water tank, for example, at the bottom area of the side of the water tank 108, or at the bottom of the water tank 108. The overflow port of the water tank 108 can be arranged at the top area of the water tank 108, for example, at the top area of the side of the water tank 108.

[0109] For example, the water tank 108 corresponds to a high water level (i.e., a first water level and / or a second water level) and a low water level (i.e., a third water level), the high water level is used to determine that the cooling liquid in the water tank 108 is sufficient, and the low water level is used to determine that the cooling liquid in the water tank 108 is empty. The overflow port is higher than the high water level, and the water draining port is lower than the low water level.

[0110] In an alternative embodiment, the water tank 108 is connected with the water injection pipeline 116 and the water discharge pipeline 117; the temperature control system further comprises a control assembly 2300 and a sensor;

Control assembly 2300 automatically controls the temperature control system based on the sensor signals transmitted by each sensor, ensuring efficient and stable operation of the system.

[0165] Figure 4A flow chart of a control method of a temperature control system according to an example embodiment of the present application is shown. The method can be performed by a control component 2300 in the temperature control system, which can be a computer device, a processor or a chip. The computer device refers to an electronic device with data computing, processing and storage capabilities.

[0166] Optionally, the control component 2300 can be a server. The server can be a standalone physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and basic cloud computing services such as big data and artificial intelligence platforms. The terminal can be a smartphone, a tablet computer, a notebook computer, a desktop computer, a smart speaker, a smart watch, etc., but is not limited thereto. The terminal and the server can be directly or indirectly connected through wired or wireless communication, which is not limited in the present application.

[0167] The method includes the following steps.

[0168] Step 210: receiving a sensing signal transmitted by a sensor.

[0169] For example, the control component 2300 is electrically connected to the sensors, the water pump 114, the water valves (e.g., the water inlet valve 119 and the water outlet valve 120), etc. in the temperature control system. The control component 2300 can receive the sensing signals reported by the sensors and automatically control the switching of the water pump 114 and the water valves according to the sensing signals, thereby realizing the automatic control of the temperature control system.

[0170] For example, the sensors include at least one of the following: an air inlet temperature sensor 121, an outdoor temperature and humidity sensor 125, a water level sensor 122, an electrical conductivity sensor 124, a water pressure sensor 123, and an air pressure difference sensor 126.

[0171] The sensing signals include at least one of the following: an air inlet temperature signal reported by the air inlet temperature sensor 121, an environmental temperature and humidity signal reported by the outdoor temperature and humidity sensor 125, a water level signal reported by the water level sensor 122, an electrical conductivity signal reported by the electrical conductivity sensor 124, a water pressure signal reported by the water pressure sensor 123, and an air pressure difference signal reported by the air pressure difference sensor 126.

[0172] Optionally, the sensors can periodically report the sensing signals to the control component 2300, the sensors can report the sensing signals to the control component 2300 at a fixed time, or the sensors can report the sensing signals to the control component 2300 in response to a reporting instruction from the control component 2300.

[0173] Step 230: controlling the operation of the water supply pipeline 106 according to the sensing signal.

[0174] Optionally, the control component 2300 can control the opening and closing of the water pump 114 in the water supply pipeline 106 according to the sensing signal. The control component 2300 can also control the opening and closing of the water injection valve 119 according to the sensing signal. The control component 2300 can also control the opening and closing of the water discharge valve 120 according to the sensing signal. The control component 2300 can also generate corresponding alarm information according to the abnormal situation indicated by the sensing signal.

[0175] In summary, the method provided by the embodiment can detect the operation of the temperature control system in real time by setting a plurality of sensors in the temperature control system, so as to timely handle and solve the abnormal situation. The control component 2300 can realize automatic control of the temperature control system according to the sensing signal transmitted by each sensor, and ensure efficient and stable operation of the temperature control system.

[0176] In an alternative embodiment, the control component 2300 can control the water pump 114 to be automatically turned on according to the ambient temperature. The control component 2300 can also control automatic water replenishment according to the water level in the water tank 108.

[0177] Figure 5 A flowchart of the control method of the temperature control system provided by an example embodiment of the present application is shown. The method can be performed by the control component 2300 in the temperature control system, which can be a computer device or a processor. The computer device refers to an electronic device with data calculation, processing and storage capabilities. Based on the above description, the control component 2300 can be a computer device or a processor. Figure 4 In the embodiment shown, step 210 includes step 211, and step 230 includes step 231.

[0178] Step 211: receiving the air inlet temperature signal transmitted by the air inlet temperature sensor 121.

[0179] For example, the sensors include the air inlet temperature sensor 121 for detecting the air inlet temperature of the condenser 102, the sensing signal includes the air inlet temperature signal corresponding to the air inlet temperature sensor 121, and the water supply pipeline 106 is provided with the water pump 114.

[0180] When the air inlet temperature of the condenser 102 is high, the condensing efficiency of the condenser 102 is low, at which time the wet membrane 101 needs to be activated to reduce the air inlet temperature of the condenser 102 and improve the condensing efficiency of the condenser 102. If the air inlet temperature of the condenser 102 is low, the wet membrane 101 does not need to be activated.

[0181] Step 231: In the case that the inlet air temperature indicated by the inlet air temperature signal is higher than the temperature threshold, the water pump 114 is controlled to be turned on; the water pump 114 is used to deliver the cooling liquid to the wet membrane 101.

[0182] The temperature threshold can be a preset value, or the temperature threshold can be a value determined by the control component 2300 according to the current running state of the temperature control device, or the temperature threshold can be a value determined by the control component 2300 according to the current running state of the temperature control device and the outdoor temperature.

[0183] For example, when the current target temperature of the temperature control device belongs to the first temperature interval, the temperature threshold is the first value; when the current target temperature of the temperature control device belongs to the second temperature interval, the temperature threshold is the second value.

[0184] Or, when the difference between the current target temperature of the temperature control device and the outdoor temperature is greater than the first threshold, the temperature threshold is the third value; when the difference between the current target temperature of the temperature control device and the outdoor temperature is less than the first threshold, the temperature threshold is the fourth value.

[0185] That is, when the temperature control device needs to run at high load (for example, the target temperature is too high or too low, or the indoor and outdoor temperature difference is large), the temperature threshold can be set to a smaller value to facilitate the use of the wet membrane 101 to improve the running efficiency of the temperature control device. When the temperature control device does not need to run at high load, the temperature threshold can be set to a larger value, and the wet membrane 101 is not used to reduce the energy consumption of the temperature control system.

[0186] When the inlet air temperature of the condenser 102 is high, the remaining amount of the condensate in the water tank 108 needs to be detected when the water pump 114 is turned on. If the remaining amount is too low, it is insufficient to enable the wet membrane 101, and the condensate needs to be supplemented to the water tank 108.

[0187] For example, the sensor further includes a water level sensor 122 for detecting the water level of the condensate in the water tank 108; the sensing signal further includes a water level signal corresponding to the water level sensor 122. The control component 2300 receives the water level signal reported by the water level sensor 122. The control component 2300 controls the water pump 114 to be turned on in the case that the inlet air temperature indicated by the inlet air temperature signal is higher than the temperature threshold, and the water level indicated by the water level signal is higher than a first water level.

[0188] In the case that the water level indicated by the water level signal is not higher than the first water level, the water injection valve 119 is controlled to be turned on; the water injection valve 119 is used to control the injection and stop of the injection of the cooling liquid in the water tank 108; in the case that the water level indicated by the water level signal is higher than a second water level, the water injection valve 119 is controlled to be closed; the water pump 114 is controlled to be turned on. The second water level is not lower than the first water level.

[0189] The first water level can be the lowest working water level of the water tank 108, and if the remaining amount of the coolant in the water tank 108 is lower than the first water level, the wet film 101 cannot be activated. The second water level can be the high water level of the water tank 108, and if the water level is higher than the second water level, there is a risk of overflow of the coolant. The first water level and the second water level can be the same or different.

[0190] Optionally, the water level sensor 122 can periodically report the water level signal to the control component 2300. The control component 2300 can also actively send a reporting instruction to the water level sensor 122 when the wet film needs to be activated (for example, when the air inlet temperature is higher than the temperature threshold), instructing the water level sensor 122 to report the water level signal.

[0191] In summary, the method provided by the embodiment can detect the air inlet temperature of the condenser 102 in real time by arranging the air inlet temperature sensor before the air inlet surface 111 of the condenser 102, and automatically start the water pump 114 to activate the wet film 101 to reduce the air inlet temperature when the air inlet temperature is too high.

[0192] The method provided by the embodiment can also detect the remaining amount of the coolant in the water tank 108 by arranging the water level sensor 122 in the water tank 108 before starting the water pump 114, and start the water pump 114 when the remaining amount of the coolant is sufficient to start the water pump 114, and automatically control the water injection valve 119 to open to supplement the remaining amount of the coolant in the water tank 108 when the remaining amount is insufficient to start the water pump 114. Start the water pump 114 after the remaining amount of the coolant is sufficient to avoid the water pump 114 from idling and avoid the water pump 114 from wearing out.

[0193] In an alternative embodiment, after the water pump 114 is started, the control component 2300 can detect the blockage and flow interruption of the water pump 114 according to the water pressure in the water supply pipeline 106, and control the water pump 114 to stop.

[0194] Figure 6 A flow chart of a control method of a temperature control system provided by an example embodiment of the present application is shown. The method can be performed by a control component 2300 in the temperature control system, which can be a computer device or a processor. The computer device refers to an electronic device with data calculation, processing and storage capabilities. Based on the Figure 4 In the embodiment shown, step 230 includes step 232 and step 233.

[0195] After the water pump 114 is started, the water pressure sensor 123 periodically reports the water pressure signal to the control component 2300. The control component 2300 receives the water pressure signal transmitted by the water pressure sensor 123.

[0196] Step 232: generating a water pump clogging alarm and controlling the water pump 114 to be closed when the water pressure indicated by the water pressure signal is higher than the first pressure value; the water pump 114 is configured to deliver the cooling liquid to the wet membrane 101.

[0197] For example, the sensor includes a water pressure sensor 123 arranged in the water delivery pipeline 106, the water pressure sensor 123 being configured to detect the water pressure in the water delivery pipeline 106; the sensing signal includes a water pressure signal corresponding to the water pressure sensor 123; and the water delivery pipeline 106 is provided with the water pump 114.

[0198] If the water pressure in the water delivery pipeline 106 is too high, the water delivery pipeline 106 and the water pump 114 can be damaged, and the wet membrane 101 system needs to be stopped to check and eliminate the abnormality in time. Therefore, by arranging the water pressure sensor in the water delivery pipeline 106, the water pressure in the water delivery pipeline 106 is detected in real time, and when the water pressure is too high and the water pump 114 is at risk of being clogged, the control component 2300 controls the water pump 114 to be closed and generates a water pump clogging alarm to remind the user that the water pump 114 is abnormal.

[0199] Step 233: generating a water pump clogging alarm and controlling the water pump 114 to be closed when the water pressure indicated by the water pressure signal is lower than the second pressure value.

[0200] If the water pressure in the water delivery pipeline 106 is too low, the water delivery pipeline 106 can be clogged, and the control component 2300 controls the water pump 114 to be closed and generates a water pump clogging alarm to remind the user to check the water pump 114.

[0201] In summary, the method provided in the embodiment can detect the working state of the water pump 114 in real time by arranging the water pressure sensor in the water delivery pipeline 106 during the operation of the wet membrane 101 system, and automatically close the water pump 114 when the water pressure is too high or too low, and generate corresponding alarm information to remind the user to check the abnormality and eliminate the risk in time, thereby ensuring the stable operation of the wet membrane 101 system.

[0202] In an alternative embodiment, after the water pump 114 is turned on, the control component 2300 can detect the water quality of the cooling liquid according to the electrical conductivity, and automatically replace the cooling liquid in the water tank 108 when the water quality is poor.

[0203] Figure 7 A flowchart of a control method of a temperature control system is shown, which is provided in an example embodiment of the present application. The method can be performed by a control component 2300 in the temperature control system, which can be a computer device or a processor. The computer device refers to an electronic device with data calculation, processing and storage capabilities. Based on the example embodiment shown, step 230 includes step 234, and step 230 further includes step 240 and step 250. Figure 4 ​

[0204] After the water pump 114 is turned on, the conductivity sensor 124 periodically reports the conductivity signal to the control component 2300. The control component 2300 receives the conductivity signal reported by the conductivity sensor 124.

[0205] Step 234: In the case that the conductivity indicated by the conductivity signal is higher than the first conductivity value, the water pump 114 is controlled to be turned off, and the drain valve 120 is controlled to be turned on; the water pump 114 is used to deliver the coolant to the wet membrane 101; and the drain valve 120 is used to control the draining and stopping of the draining of the coolant in the water tank 108.

[0206] The control component 2300 detects the water quality of the coolant in the water tank 108 through the conductivity sensor. When the conductivity is high, it indicates that the coolant contains more impurities and the water quality is poor. When the conductivity is low, it indicates that the coolant contains less impurities and the water quality is good.

[0207] Therefore, when the control component 2300 detects that the conductivity is higher than the first conductivity value, it indicates that the coolant in the current wet membrane system contains too many impurities and is not suitable for continued use. Therefore, the control component 2300 controls the water pump 114 to be turned off, and controls the drain valve 120 to be turned on to drain the coolant in the water tank 108.

[0208] For example, the control component 2300 receives the water level signal reported by the water level sensor 122, determines the current water level in the water tank according to the water level signal, and controls the opening and closing of the water injection valve 119 and the drain valve 120 to drain the original coolant in the water tank 108 and re-inject new coolant.

[0209] Step 240: In the case that the water level indicated by the water level signal is lower than the third water level, the drain valve 120 is controlled to be turned off, and the water injection valve 119 is controlled to be turned on; the water injection valve 119 is used to control the injection and stopping of the injection of the coolant in the water tank 108.

[0210] When the remaining amount of the coolant in the water tank 108 is lower than the third water level, it indicates that the coolant in the water tank 108 has been drained, and the control component 2300 controls the drain valve 120 to be turned off and the water injection valve 119 to be turned on to re-inject the coolant into the water tank 108.

[0211] Step 250: In the case that the water level indicated by the water level signal is higher than the second water level, the water injection valve 119 is controlled to be turned off.

[0212] For example, after the water injection valve 119 is turned off, the water pump 114 is controlled to be turned on again.

[0213] When the remaining amount of the coolant in the water tank 108 is higher than the second water level, it indicates that the replenishment of the coolant is complete, and the water injection valve 119 is turned off to stop the injection of the coolant. At this time, the water pump 114 can be turned on again to continue to use the wet membrane system.

[0214] In summary, the method provided by the embodiment can detect the water quality of the condensate in real time through the conductivity sensor arranged in the water tank 108, and the condensate can be automatically replaced when the water quality of the condensate is poor, so that the condensate used in the wet membrane system always has good water quality.

[0215] In an alternative embodiment, after the water pump 114 is turned on, the control component 2300 can calculate the wet membrane efficiency through the temperature signals reported by the air inlet temperature sensor 121 and the outdoor temperature and humidity sensor 125, and generate an alarm information when the wet membrane efficiency is too low.

[0216] Figure 8 A flowchart of a control method of a temperature control system provided by an example embodiment of the application is shown. The method can be performed by a control component 2300 in the temperature control system, which can be a computer device or a processor. The computer device refers to an electronic device with data calculation, processing and storage capabilities. Based on the example embodiment shown, the method further includes step 260. Figure 4 The example embodiment shown, the method further includes step 260.

[0217] After the water pump 114 is turned on, the air inlet temperature sensor 121 periodically reports the air inlet temperature signal to the control component 2300. The control component 2300 receives the air inlet temperature signal reported by the air inlet temperature sensor 121. The outdoor temperature and humidity sensor 125 periodically reports the environmental temperature and humidity signal to the control component 2300. The control component 2300 receives the environmental temperature and humidity signal reported by the outdoor temperature and humidity sensor 125.

[0218] Step 260: generating a wet membrane efficiency abnormality alarm when the wet membrane efficiency is lower than the efficiency threshold, the wet membrane efficiency being calculated according to the air inlet temperature signal and the environmental temperature and humidity signal.

[0219] For example, the air inlet temperature signal includes the air inlet dry-bulb temperature; the environmental temperature and humidity signal includes the environmental dry-bulb temperature and the environmental relative humidity; the control component 2300 calculates a first difference value between the environmental dry-bulb temperature and the air inlet dry-bulb temperature; calculates a second difference value between the environmental dry-bulb temperature and the environmental wet-bulb temperature, the environmental wet-bulb temperature being calculated according to the environmental dry-bulb temperature and the environmental relative humidity; and determines the ratio of the first difference value to the second difference value as the wet membrane efficiency.

[0220] Alternatively, the wet membrane efficiency can also be the ratio of the environmental temperature to the air inlet temperature.

[0221] In summary, the method provided by the embodiment can detect the water quality of the condensate in real time through the conductivity sensor arranged in the water tank 108, and the condensate can be automatically replaced when the water quality of the condensate is poor, so that the condensate used in the wet membrane system always has good water quality.

[0222] In an alternative embodiment, after the water pump 114 is turned on, the control component 2300 can detect the air pressure difference between the air inlet surface 109 and the air outlet surface 110 of the wet membrane 101 in real time through the air pressure difference sensor 126. When the air pressure difference is large, it is determined that the wet membrane 101 is blocked, and an alarm information is generated.

[0223] Figure 9 A flow chart of a control method of a temperature control system according to an example embodiment is shown. The method can be performed by a control component 2300 in the temperature control system, which can be a computer device or a processor. The computer device refers to an electronic device with data computing, processing and storage capabilities. Based on the example embodiment shown, the method further includes step 270. Figure 4

[0224] After the water pump 114 is turned on, the air pressure difference sensor 126 periodically reports the air pressure difference signal to the control component 2300. The control component 2300 receives the air pressure difference signal reported by the air pressure difference sensor 126.

[0225] Step 270: generating a wet membrane blockage alarm when the air pressure difference indicated by the air pressure difference signal is higher than the first air pressure difference.

[0226] For example, by detecting the air pressure difference between the air inlet surface and the air outlet surface of the wet membrane 101, the blockage of the wet membrane 101 can be detected. When the air pressure difference is large, it indicates that the wet membrane 101 is blocked seriously, which will reduce the cooling efficiency of the condenser 102. Therefore, the control component 2300 generates a wet membrane blockage alarm in time to remind the user to clean up.

[0227] In summary, the method provided in the embodiment can automatically detect the blockage of the wet membrane 101 and generate a wet membrane blockage alarm in time when the wet membrane 101 is blocked.

[0228] An example embodiment combining the above Figures 5 to 9 is given.

[0229] Figure 10 A flow chart of a control method of a temperature control system according to an example embodiment is shown. The method can be performed by a control component 2300 in the temperature control system, which can be a computer device or a processor. The computer device refers to an electronic device with data computing, processing and storage capabilities. The method includes the following steps.

[0230] Step 301: The air inlet temperature sensor 121 detects the air inlet temperature of the condenser 102 and reports the air inlet temperature to the control component 2300.

[0231] ​Step 302, the control component 2300 determines whether the inlet air temperature exceeds the set value of the wet condition. If it exceeds the set value, it enters the wet condition operation, and the wet film 101 is enabled to reduce the inlet air temperature of the condenser 102; if it does not exceed, it remains in the current dry condition operation state.

[0232] After the temperature control system is started, the control component 2300 detects the inlet air temperature of the condenser 102. If it exceeds the set value, it enters the wet condition and prepares to start the water pump 114.

[0233] Step 303, the control component 2300 detects whether the water in the water tank 108 exceeds the high water level through the water level sensor 122. If it does not exceed, the water filling valve 119 is opened to supplement the water to the high water level. If it exceeds, the water pump 114 is started to supplement water for the wet film 101, and the wet condition operation is entered.

[0234] Before the water pump 114 is started, the water level in the water tank 108 needs to be determined to prevent the water pump 114 from idling or cavitation. At this time, the water level in the water tank 108 is detected. If the water level exceeds the set high water level (for example, the first water level or the second water level), the water pump 114 is directly started. If the water level is lower than the high water level, the water filling valve 119 is started to supplement the water to the high water level before the water pump 114 is started.

[0235] Step 304, the control component 2300 detects the water pressure of the water pump 114 during the wet condition operation through the water pressure sensor 123. If the pressure is too high, it prompts the water pump blockage alarm and closes the water pump 114 to exit the wet condition. If the pressure is too low, it prompts the water pump flow interruption alarm and closes the water pump 114 to exit the wet condition.

[0236] After the water pump 114 is started, the water pressure on the water pump 114 water delivery pipeline 106 is detected to determine the working state of the water pump 114 at this time. If it is too low, it may be that the water pump 114 has not started or is idling. If it is too high, it may have occurred pipeline blockage. Once the above two situations occur, the water pump 114 needs to be closed to exit the wet condition and wait for manual inspection of the fault cause.

[0237] Step 304, the control component 2300 detects the water level of the cooling liquid in the water tank 108 during the wet condition operation through the water level sensor 122. If the water level is lower than the low water level (for example, the third water level), the water filling valve 119 is opened to supplement the water to the medium water level (for example, the fourth water level).

[0238] As the water evaporates, the water level in the water tank 108 will become lower and lower. If the water level drops to the set low water level (for example, the third water level) during operation, the water filling valve 119 is opened for supplementation until it returns to the medium water level (for example, the fourth water level).

[0239] Among them, the first water level is higher than the fourth water level, and the fourth water level is higher than the third water level.

[0240] That is, before the water pump 114 is turned on, the control assembly 2300 needs to replenish the condensed liquid in the water tank 108 to a high water level (e.g., the first water level or the second water level); during the operation of the water pump 114, if the condensed liquid level is lower than the low water level (e.g., the third water level), the control assembly 2300 automatically replenishes water to the medium water level (e.g., the fourth water level).

[0241] In step 306, the control assembly 2300 detects whether the water quality in the water tank 108 exceeds the standard during the operation of the wet working condition through the conductivity sensor 124. If it exceeds the standard, the water pump 114 is turned off; the drain valve 120 is opened to drain water to the low water level (e.g., the third water level), the drain valve 120 is closed; the water filling valve 119 is opened to fill water to the high water level (e.g., the first water level or the second water level), the water filling valve 119 is closed; and the water pump 114 is turned on. If it does not exceed the standard, the normal operation of the wet working condition is maintained.

[0242] Salt in water and dust in air can accumulate in the water tank 108, high salt can poison the wet film 101 material, and too much silt can cause pipeline blockage and dirty blockage of the wet film, so it is necessary to detect the water quality in the water tank 108, and replace the water by draining and then filling water, during which the water pump 114 needs to stop running.

[0243] During the water quality replacement process, the control assembly 2300 needs to drain the condensed liquid in the water tank 108 to the low water level (e.g., the third water level), and then replenish the liquid to the high water level (e.g., the first water level or the second water level).

[0244] In step 307, the control assembly 2300 detects whether the wet film efficiency of the wet film 101 is normal during the operation of the wet working condition through the inlet air temperature sensor 121 and the outdoor temperature and humidity sensor 125. If it is not normal, the wet film efficiency is abnormal. If it is normal, the normal operation of the wet working condition is maintained.

[0245] In step 308, the control assembly 2300 detects whether the pressure difference before and after the wet film 101 is abnormal during the operation of the wet working condition through the wind pressure difference sensor 126. If it is abnormal, the wet film blockage alarm is prompted. If it is normal, the normal operation of the wet working condition is maintained.

[0246] During the operation of the wet film system, the temperature / humidity sensor and the wind pressure difference sensor 126 always detect the wet film efficiency and the wind pressure difference before and after the wet film. If the wet film efficiency is too low, it may be that the water distribution has a problem, causing part of the wet film to not work normally. If the wet film efficiency is too high, it may be that the temperature / humidity sensor has been damaged, giving incorrect data. If the wind pressure difference before and after the wet film 101 is too large, it may be that foreign matter is adhered to the wet film 101 or that too much dust has accumulated. These situations can cause the system efficiency to decrease but do not affect the safety of the system, so an alarm is given to remind manual inspection, without the need for further action.

[0247] Step 309, the control component 2300 detects whether there is other condition for exiting the wet working condition during the wet working condition operation, and exits the wet working condition and closes the water pump 114 if there is; otherwise, the wet working condition is normally operated.

[0248] During the wet working condition operation, the control component 2300 can cyclically execute steps 304 to 309 to detect the running condition of the wet working condition in real time.

[0249] In summary, the method provided by the embodiments of the present application is that the air inlet of the condenser 102 first passes through the wet membrane 101, the water in the wet membrane 101 is evaporated to absorb heat, and then the temperature of the air is reduced and the humidity is increased; the temperature of the air out of the wet membrane 101 is directly reduced to reduce the condensing temperature in the condenser 102, so as to achieve the purpose of reducing the energy consumption of the unit, and the nearly saturated air out of the wet membrane 101 will not carry liquid water to the condenser 102, the air passing through the condenser 102 absorbs heat to increase the temperature, and the humidity relatively decreases to keep the condenser 102 and the fan 103 dry, so that the corrosion risk of the condenser 102 and the fan 103 is greatly reduced.

[0250] The method provided by the embodiments of the present application is that the wet membrane assembly is designed for the fluorine pump double-circulation unit, the condenser 102 inlet air temperature is reduced, the purpose of reducing the compressor power consumption and reducing the compressor operation time is achieved, so that the energy consumption is saved to the greatest extent, and the safe and efficient operation of the system is ensured through auxiliary control.

[0251] The method provided by the embodiments of the present application can effectively reduce the condenser 102 inlet air temperature, so as to greatly reduce the power consumption of the compressor during operation and reduce the compressor operation time. The corrosion risk of the unit caused by the condensing liquid spray system is effectively avoided. The damage risk of the water pump 114 due to idling / locked rotor is effectively avoided. The detection of the wet membrane efficiency and the air resistance can effectively remind the maintenance personnel to pay attention to the working state of the wet membrane, and timely human intervention is performed, so that the efficiency and service life of the wet membrane are effectively improved. The detection and replacement of the water quality can effectively reduce the toxicity of salt and alkali to the wet membrane and the dirt and blockage of the wet membrane and the pipeline caused by the silt.
