Description

Technical Field

[0001] The present application relates to the technical field of concrete construction, and in particular to a concrete temperature control circulation system and a temperature control circulation control method. Background Art

[0002] During the concrete pouring process, the heat generated by the hydration reaction is difficult to dissipate quickly, resulting in heat accumulation inside the concrete, causing the internal temperature to rise abnormally. When the external ambient temperature is low, the temperature difference between the inside and outside of the concrete further increases, and the resulting thermal stress may exceed the concrete's crack resistance, causing cracks, which in turn affects the stability and durability of the concrete structure.

[0003] The traditional method is to control the temperature difference inside a large volume of concrete by arranging cooling pipe groups inside the concrete. After the concrete is poured, its temperature will undergo dynamic changes. Therefore, the water temperature in the cooling pipe group also needs to be adjusted accordingly to achieve effective control of the temperature inside the concrete. Usually, the control of the water temperature in the cooling pipe group requires the setting of a circulation pipeline and a refrigeration device or a heat pump device, and the refrigeration device or the heat pump device is used to adjust the temperature of the medium passing through the cooling pipe group.

DETAILED DESCRIPTION

[0034] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0035] See also Figures 1 to 3The concrete temperature control circulation system 10 in one embodiment of the present application can at least reduce energy consumption and improve the temperature difference control efficiency. Specifically, the concrete temperature control circulation system 10 includes a water storage component 100, a water return control valve 200, a drainage box 300, a refrigeration device 400 and a refrigeration control valve 500. A water storage chamber 110 is formed in the water storage component 100. A drainage hole 120 and a water inlet hole 130 connected to the water storage chamber 110 are provided on the water storage component 100. A water inlet pipe 600 is connected to the drainage hole 120. The end of the water inlet pipe 600 away from the water storage component 100 is used for docking and communication with the first pair of joints 202 of the cooling pipe group 20. A water return hole 140 connected to the water storage chamber 110 is also provided on the water storage component 100. The water return control valve 200 is arranged at the water return hole 140; the drainage box 300 is connected with a drainage pipe 700, and the end of the drainage pipe 700 away from the drainage box 300 is used to connect with the second joint 204 of the cooling pipe group 20. The drainage box 300 is also provided with a water outlet 310, and the water outlet 310 is connected with a circulation pipe group 320, and a first circulation channel and a second circulation channel are formed in the circulation pipe group 320, and the first circulation channel connects the water outlet 310 and the water return hole 140; the second circulation channel is connected to the refrigeration equipment 400, and the refrigeration outlet of the refrigeration equipment 400 is connected with the water return hole 140; the refrigeration control valve 500 is used to control the opening and closing of the second circulation channel.

[0036] When in use, the current drainage temperature of the water in the drainage box 300 is obtained. If the current drainage temperature is less than or equal to the current temperature of the normal temperature water, the refrigeration control valve 500 is controlled to open the second circulation channel, so that the water in the drainage box 300 enters the water storage chamber 110 of the water storage assembly 100 through the refrigeration device 400, and the water in the water storage chamber 110 is pumped to the cooling pipe group 20. If the current drainage temperature is greater than the current temperature of the normal temperature water, the refrigeration control valve 500 is controlled to close the second circulation channel, and the normal temperature water is controlled to enter the water storage chamber 110 through the refrigeration device 400, and the water in the water storage chamber 110 is controlled to be pumped to the cooling pipe group 20. In the early stage of concrete pouring, the temperature inside the concrete is not very high. At this time, the refrigeration device 400 can be used to quickly cool the cooling water to achieve the purpose of rapid cooling. When the drainage temperature is lower than the normal temperature water, the water in the drainage box 300 can be recycled to reduce the consumption of refrigeration energy of the refrigeration device 400 or improve the refrigeration effect.

[0037] Continue to obtain the current concrete temperature of the concrete and the current inlet water temperature of the water storage chamber 110, and judge that the temperature difference between the current concrete temperature and the current inlet water temperature is greater than the safety temperature difference threshold, then control the refrigeration equipment 400 to stop running, and control the normal temperature water and / or the water in the drainage box 300 to be transported to the water storage chamber 110, so that the temperature difference between the current concrete temperature and the current inlet water temperature is less than or equal to the safety temperature difference threshold. As the construction continues, the temperature of the concrete gradually increases. If the temperature difference between the temperature of the cooling pipe group 20 and the temperature of the concrete is too large, it will cause the fission of the concrete. Therefore, the temperature difference between the current concrete temperature and the current inlet water temperature is greater than the safety temperature difference threshold, and there is no need to refrigerate the circulating cooling water. By controlling part or all of the water in the drainage box 300 to be transported to the water storage chamber 110, it is convenient to recover the heat of the discharged circulating cooling water and maintain the temperature difference between the current inlet water temperature and the current concrete temperature. By arranging and connecting the components and pipelines in the concrete temperature control circulation system 10, it is possible to reduce the energy consumption of the refrigeration equipment 400, improve the efficiency of energy recovery and utilization, and improve the efficiency of temperature difference control.

[0038] In one embodiment, the return water control valve 200 is a three-way control valve, and the circulation pipe group 320 includes a circulation main pipe 321 and two circulation branches 322. One end of the circulation main pipe 321 is connected to the water outlet hole 310, and the other end is connected to the two circulation branches 322. One end of a circulation branch pipe 322 away from the circulation main pipe 321 is connected to the refrigeration equipment 400, and the other end of the circulation branch pipe 322 away from the circulation main pipe 321 is connected to a pair of interfaces of the return water control valve 200. The other two interfaces of the return water control valve 200 are respectively connected to the return water hole 140 and the refrigeration outlet of the refrigeration equipment 400. The return water control valve 200 is controlled to connect the circulation branch pipe 322 with the return water hole 140 or connect the refrigeration equipment 400 with the return water hole 140. By setting the return water control valve 200 as a three-way control valve, it is possible to facilitate effective connection between the water storage component 100, the drainage tank 300 and the refrigeration equipment 400, and it is possible to selectively control the connection between the drainage tank 300 and the water storage chamber 110 of the water storage component 100 or control the water storage chamber 110 to be directly connected to the refrigeration equipment 400, thereby achieving regulation of the two circulation states of the system.

[0039] In other embodiments, the return water control valve 200 may also have other types of valve body structures, as long as it can selectively connect the drainage box 300 with the water storage chamber 110 of the water storage assembly 100 or control the water storage chamber 110 to be directly connected with the refrigeration equipment 400.

[0040] In one embodiment, the water inlet of the refrigeration device 400 is also connected to an external water inlet pipe 600, and external tap water or other cooling media can enter the refrigeration device 400 for cooling. At this time, the water passing through the concrete is discharged into the drainage box 300, realizing external circulation control of cooling and improving the cooling efficiency.

[0041] In one embodiment, the refrigeration control valve 500 is a three-way control valve, and the circulation main pipe 321 and the two circulation branches 322 are respectively connected to the three docking ports of the refrigeration control valve 500, and the refrigeration control valve 500 is controlled to select one of the circulation branches 322 to be connected to the circulation main pipe 321. By setting the refrigeration control valve 500 as a three-way control valve, it is convenient to realize the connection between the circulation main pipe 321 and the two circulation branches 322, and to realize the communication between the circulation main pipe 321 and one of the circulation branches 322. In other embodiments, the refrigeration control valve 500 can be set at the connection between the refrigeration equipment 400 and the circulation branch 322 or on the circulation branch 322 connected to the refrigeration equipment 400, and is used to control the connection and disconnection between the refrigeration equipment 400 and the drainage tank 300.

[0042] In this embodiment, the concrete temperature control circulation system 10 further includes a heater 800, which is disposed in the water storage chamber 110, and the heater 800 is used to heat the water in the water storage chamber 110. When the concrete is poured to the middle and late stages, the temperature inside the concrete is relatively high. In order to avoid a large temperature difference between the cooling pipe and the concrete, the water entering the concrete needs to be heated to control the temperature difference. After the heater 800 is turned on, the water in the drainage box 300 can be controlled to be transported to the water storage chamber 110, thereby reducing or even avoiding the addition of new water resources, and at the same time, the heat of the drained water can be effectively recovered to reduce energy consumption.

[0043] In one embodiment, the concrete temperature control circulation system 10 further includes a first temperature detector, a second temperature detector and a temperature control module, wherein the first temperature detector is used to detect the outlet temperature of water from the water storage chamber 110, the second temperature detector is used to detect the temperature of concrete, the first temperature detector, the second temperature detector, the heater 800 and the refrigeration device 400 are all electrically connected to the temperature control module, and the temperature control module is used to control the operation of the heater 800 and the refrigeration device 400 according to the monitoring results of the first temperature detector and the second temperature detector. The current temperature of the concrete can be obtained through the second temperature detector, in order to control the temperature difference between the cooling pipe group 20 and the concrete temperature to be not greater than the safe temperature difference threshold, and then the operation of the heater 800 or the refrigeration device 400 can be controlled according to the result detected by the second temperature detector, so as to control the data detected by the first temperature detector and ensure the cooling effect on the concrete.

[0044] In this embodiment, the concrete temperature control circulation system 10 further includes a third temperature detector, which is used to detect the temperature of the cooling medium in the drainage box 300, and the temperature control module is used to control the return water control valve 200 and the refrigeration control valve 500 according to the monitoring result of the third temperature detector. By detecting the temperature in the drainage box 300 by the third temperature detector, it is possible to easily implement and decide whether to recycle the water in the drainage box 300. For example, when the temperature in the drainage box 300 is lower than the normal temperature, the water in the drainage box 300 is controlled to enter the refrigeration device 400. When the refrigeration device 400 is turned off, the proportion of the water in the drainage box 300 transported to the water storage chamber 110 is adjusted according to the water temperature in the drainage box 300 and the water temperature of the normal temperature water, so as to adjust the appropriate outlet water temperature. When the required inlet water temperature entering the cooling pipe group 20 is higher than the water temperature in the drainage box 300, the water in the drainage box 300 can be controlled to be transported to the water storage chamber 110, and the heater 800 is started for heating. Specifically, a flow meter is provided on the pipe connecting the drainage box 300 and the water storage chamber 110 , and a flow meter is provided at the water inlet 130 of the water storage assembly 100 .

[0045] In one embodiment, the concrete temperature control circulation system 10 further includes a water return pipe 210 , one end of the water return pipe 210 is connected to the water return hole 140 , and the other end is connected to the water return control valve 200 .

[0046] In one embodiment, the concrete temperature control circulation system 10 further includes a water pump 610 , which is disposed on the water inlet pipe 600 , and is used to provide power for the cooling medium in a direction from the water storage chamber 110 to the water inlet pipe 600 .

[0047] See also Figure 1 and Figure 4 In one embodiment, the concrete temperature control circulation system 10 further includes a first water distributor, a second water distributor and a plurality of cooling tube groups 20. The plurality of cooling tube groups 20 are divided into at least two layers and laid in the concrete. The cooling tube groups 20 of different layers are arranged at intervals from top to bottom. The first pair of joints 202 of the cooling tube groups 20 of different layers are connected to the water inlet pipe 600 through the first water distributor, and the second pair of joints 204 of the cooling tube groups 20 of different layers are connected to the drain pipe 700 through the second water distributor. A water inlet control valve is arranged on each layer of the cooling tube groups 20. Since the concrete casting has a certain thickness, the cooling effect of the concrete can be improved by arranging at least two layers of cooling tube groups 20.

[0048] For example, in this embodiment, the concrete temperature control circulation system 10 is used in the foundation casting construction. Three layers of cooling pipe groups 20 are arranged in a section of the foundation to be cast. Each layer of cooling pipe group 20 controls whether the water inlet control valve is opened.

[0049] See also Figure 3 , Figure 5 and Figure 6 In one embodiment, the water storage assembly 100 includes a water storage tank 150, a partition 160 and a switch unit 170. The water storage tank 150 is hollow. The partition 160 is disposed in the water storage tank 150 and divides the space in the water storage tank 150 to form a water storage chamber 110 and a water storage chamber 152. The water inlet 130 is connected to the water storage chamber 152. The partition 160 is provided with a connecting hole 162. The switch unit 170 is openably covered on the connecting hole 162, and the size of the connecting hole 162 is larger than the size of the water inlet 130. Since the cooling tube group 20 is provided with at least two layers, when another layer of the cooling tube group 20 is started, the water supply flow rate suddenly increases, and the water storage capacity in the water storage chamber 110 is limited, which will cause the water in the water storage chamber 110 to decrease rapidly. Therefore, some water can be stored in the water storage chamber 152 in advance. Since the size of the connecting hole 162 is larger than the size of the water inlet hole 130, when the water in the water storage chamber 110 decreases rapidly, the water in the water storage chamber 152 is quickly replenished into the water storage chamber 110 through the connecting hole 162 to meet the sudden increase in flow requirement.

[0050] In this embodiment, the water storage chamber 152 is located above the water storage chamber 110. When the water in the water storage chamber 110 decreases, the water in the water storage chamber 152 can be automatically replenished into the water storage chamber 110 through the connecting hole 162 under the action of its own weight. Specifically, the space of the water storage chamber 152 is smaller than the space of the water storage chamber 110, and the depth of the water storage chamber 152 is smaller than the depth of the water storage chamber 110. Under the premise of meeting the requirement of rapid water replenishment, the volume of the water storage box 150 is prevented from being too large.

[0051] In one embodiment, the switch unit 170 includes a floating plug body 172 and a guide portion 174. The floating plug body 172 is located in the water storage chamber 110. The guide portion 174 is connected to the floating plug body 172. A matching portion 112 is provided in the water storage chamber 110. The guide portion 174 and the matching portion 112 are guided and matched along the direction from the water storage chamber 110 to the water storage chamber 152. The floating plug body 172 can float in the water storage chamber 110 and can be plugged into the communication hole 162. When the water in the water storage chamber 110 is relatively full, under the guidance and cooperation of the guide portion 174 and the matching portion 112 and the buoyancy of the floating plug body 172, the floating plug body 172 floats up and can be plugged into the communication hole 162, thereby separating the water storage chamber 152 from the water storage chamber 110. When the water level in the water storage chamber 110 drops, the buoyancy of the floating plug 172 decreases, and the floating plug 172 disengages from the connecting hole 162 to connect the water storage chamber 152 with the water storage chamber 110, so that the water in the water storage chamber 152 can be quickly replenished into the water storage chamber 110.

[0052] See also Figures 5 to 7In one embodiment, the upper surface of the floating plug body 172 is a spherical crown surface, and the upper surface of the floating plug body 172 can abut against the inner wall of the connecting hole 162.

By providing at least two guide portions 174, it is convenient to improve the stability of the floating plug body 172 so that the floating plug body 172 can be stably inserted into the communicating hole 162.

The water storage assembly 100 allows water to enter the concrete through the balanced cooling module 900. After passing through the concrete, the cooling water passes through the balanced cooling module 900 and is discharged into the drainage box 300. By providing the balanced cooling module 900, the uniformity of cooling the concrete can be improved, and excessive local temperature differences can be reduced or avoided.

[0056] Specifically, the balanced cooling module 900 includes a first water outlet pipe group 910, a second water outlet pipe group 920, a first control valve 930, a drain pipe 940 and a second control valve 950. The first water outlet pipe group 910 includes a first main water outlet pipe 912 and at least two first water outlet branches 914. One end of each first water outlet branch pipe 914 is connected to the first main water outlet pipe 912, and the other end is respectively connected to the first pair of joints 202 of each cooling pipe group 20; the second water outlet pipe group 920 includes a second main water outlet pipe 922 and at least two second water outlet branches 924. One end of each second water outlet branch pipe 924 is connected to the second main water outlet pipe 922, and the other end is respectively connected to the second pair of joints 204 of each cooling pipe group 20. One end of the first main water outlet pipe 912 away from the first water outlet branch pipe 914 and one end of the second main water outlet pipe 922 away from the second water outlet branch pipe 924 are both connected to the first control valve 930. The first control valve 930 is used to control the cooling medium in the water storage chamber 110 of the water storage assembly 100 to flow into the first main water outlet pipe 912 or into the second main water outlet pipe 922. One end of the drain pipe 940 is connected to the first water outlet pipe group 910; one end of the drain pipe 700 away from the drain box 300 is connected to the second water outlet pipe group 920 through the second control valve 950, and the other end of the drain pipe 940 is connected to the second control valve 950. The second control valve 950 is used to control the second water outlet pipe group 920 to be connected to the drain pipe 700 or to control the drain pipe 940 to be connected to the drain pipe 700.

[0057] When in use, the first temperature of the area near the first joint 202 of the cooling tube group 20 and the second temperature of the area near the second joint 204 of the cooling tube group 20 are obtained, and the first temperature and the second temperature are compared; if the first temperature is greater than the second temperature, the second control valve 950 is controlled to connect the second outlet pipe group 920 and the drain pipe 700, and the first control valve 930 is controlled to connect the first main outlet pipe 912, so that the cooling medium flows into the cooling tube group 20 through the first main outlet pipe 912 and the first outlet branch pipe 914 and the first joint 202, and is discharged from the drain pipe 700 through the second outlet pipe group 920 and the second control valve 950. At this time, the water discharged through the water storage chamber 110 first flows into the cooling tube group 20 from the first joint 202 through the first outlet pipe group 910, and the temperature near the first joint 202 is first reduced. If the first temperature is lower than the second temperature, the second control valve 950 is controlled to connect the drain pipe 940 and the drain pipe 700, and the first control valve 930 is controlled to connect the second main water outlet pipe 922, so that the cooling medium flows into the cooling pipe group 20 through the second main water outlet pipe 922 and the second water outlet branch pipe 924 and the second joint 204, and is discharged from the drain pipe 700 through the first water outlet pipe group 910 and the drain pipe 940. At this time, the water discharged through the water storage chamber 110 first enters the cooling pipe group 20 through the second joint 204 through the second water outlet pipe group 920, thereby reducing the stability near the second joint 204. When switching the water flow mode, the above-mentioned balanced cooling module 900 only needs to control the first control valve 930 and the second control valve 950, and keep the water storage chamber 110 always discharging water, and the drainage box 300 always receives the discharged water. It will not change the temperature control method of the refrigeration equipment 400 or the heater 800 for the circulating water, and there is no need to change the connection control relationship between the water storage component 100, the drainage and the refrigeration equipment 400.

[0058] In this embodiment, the cooling tube group 20 is provided with multiple layers, and a balanced cooling module 900 can be provided for each layer of the cooling tube group 20, or only one balanced cooling module 900 can be provided, or a balanced cooling module 900 can be provided for two or more layers.

[0059] In one embodiment, the first control valve 930 is a three-way control valve, and one end of the water inlet pipe 600 away from the water storage assembly 100, the first main water outlet pipe 912, and the second main water outlet pipe 922 are respectively connected to three interfaces of the first control valve 930. By setting the first control valve 930 as a three-way control valve, it is convenient to control the water inlet pipe 600 to be connected with the first main water outlet pipe 912 or the second main water outlet pipe 922, thereby facilitating the control of the circulation flow direction of the cooling water.

[0060] Specifically, the balanced cooling module 900 further includes a first temperature sensor and a second temperature sensor. The first control valve 930, the first temperature sensor and the second temperature sensor are all electrically connected to the temperature control module. The first temperature sensor is used to be arranged at a position of the cooling tube group 20 close to the first pair of joints 202, and the second temperature sensor is used to be arranged at a position of the cooling tube group 20 close to the second pair of joints 204. The temperature control module is used to collect temperature data of the first temperature sensor and the second temperature sensor, and control the first control valve 930 to connect the water inlet pipe 600 with the first main water outlet pipe 912 or the water inlet pipe 600 with the second main water outlet pipe 922 according to the collected results. The first temperature sensor is arranged to facilitate the detection of the temperature near the first pair of joints 202, and the second temperature sensor is used to facilitate the detection of the temperature near the second pair of joints 204, thereby facilitating the control of the first control valve 930.

[0061] In this embodiment, the first pair of joints 202 of each cooling pipe group 20 are close to each other and are located in the middle of the concrete to be measured or near the middle, the second pair of joints 204 of each cooling pipe group 20 are located near the edge of the concrete to be measured, the middle of the concrete to be measured or near the middle is provided with a first temperature sensor, and the edge of the concrete to be measured is provided with a second temperature sensor. Further, at least two different temperature control areas are formed in the concrete to be measured, each temperature control area is arranged with at least one cooling pipe group 20, and each temperature control area is provided with a regional temperature sensor.

[0062] In one embodiment, the balanced cooling module 900 further includes a proportional distribution valve 960, and each first water outlet branch pipe 914 is connected to the first main water outlet pipe 912 through the proportional distribution valve 960. The balanced cooling module 900 further includes at least two first water temperature sensors and at least two second water temperature sensors, each first water temperature sensor is used to detect the temperature of the cooling medium at the first pair of joints 202 of the cooling pipe group 20, and each second water temperature sensor is used to detect the temperature of the cooling medium at the second pair of joints 204 of the cooling pipe group 20. The temperature control module is used to collect temperature data of the first water temperature sensor and each second water temperature sensor, and control the proportional distribution valve 960 to adjust the flow of each first water outlet branch pipe 914 according to the collected results. In this embodiment, the first water temperature sensor can be the first temperature sensor in the above embodiment, and the second water temperature sensor can be the second temperature sensor in the above embodiment.

[0063] The temperature difference between the outlet water temperature and the inlet water temperature of different cooling tube groups 20 can be obtained by the first water temperature sensor and the second water temperature sensor, and the cooling tube group 20 with a temperature difference greater than or equal to the preset difference and the cooling tube group 20 with a temperature difference less than the preset difference can be judged. For example, when two cooling tube groups 20 are compared, the flow rate of the cooling tube group 20 with a small temperature difference is adjusted to reduce the flow rate of the cooling tube group 20 with a large temperature difference, and the flow rate of the cooling tube group 20 with a large temperature difference is increased to reduce the temperature difference of the cooling tube group 20 with a large temperature difference, thereby improving the temperature balance in the concrete. For example, when the difference between the outlet water temperature and the inlet water temperature of the two cooling tube groups 20 is greater than 10°C, and the temperature difference on both sides is unbalanced, the distribution ratio of the water entering the two sides is controlled to reduce the temperature difference and improve the temperature balance.

[0064] In another embodiment, at least two different temperature control areas are formed in the concrete to be tested, at least one cooling pipe group 20 is arranged in each temperature control area, and a regional temperature sensor is arranged in each temperature control area. Each of the regional temperature sensors is electrically connected to the temperature control module, and the temperature control module is used to collect the temperature of each of the regional temperature sensors, and control the proportional distribution valve to adjust the flow of each of the first water outlet branches 914 according to the collected results. By detecting the temperature of each temperature control area, when the temperature difference between the temperature control areas is large, it proves that the temperature reduction inside the concrete is uneven, and the flow of the cooling pipe group 20 in the high temperature area can be increased to improve the heat exchange efficiency and reduce the flow of the low temperature area.

[0065] In one embodiment, the second control valve 950 is a three-way control valve, and the second main water outlet pipe 922, the drain pipe 940 and the drain pipe 700 are respectively connected to the three interfaces of the second control valve 950. The second control valve 950 is controlled to connect the drain pipe 940 and the drain pipe 700 or the second main water outlet pipe 922 and the drain pipe 700; and the connection position of the second outlet branch pipe 924 and the second main water outlet pipe 922 is located between the first control valve 930 and the second control valve 950. By setting the second control valve 950 as a three-way control valve, it is convenient to control the on-off of the drain pipe 940, and then it can control the drainage to be effectively discharged through the drain pipe 700.

[0066] In the above embodiment, in the process of adjusting the cooling medium flow direction to adjust the cooling balance of concrete, the temperature difference between the inlet temperature of the cooling medium and the maximum temperature of the concrete needs to be controlled within the safe temperature difference threshold. For example, the safe temperature difference threshold can be 25°C or 20°C to avoid excessive temperature difference between the inlet temperature and the maximum temperature of the concrete, which may cause fission of the concrete.

[0068] In one embodiment, the temperature control cycle control method further includes: Obtain the current water inlet temperature range based on the current concrete temperature and the safe temperature difference threshold; If the current drainage temperature is within or lower than the current water inlet temperature range, the water in the drainage box 300 is controlled to be transported to the water storage chamber 110 .

[0069] In this embodiment, the difference between the inlet water temperature and the internal temperature of the concrete is set to 25°C during the temperature rise period, that is, when the inlet water temperature and the highest temperature of the concrete are within 25°C, the refrigeration device 400 continues to work to reduce the inlet water temperature. When the inlet water temperature and the highest concrete temperature are greater than 25°C, the refrigeration device 400 stops working, and then controls the heater 800 to start and the water volume delivered to the water storage chamber 110 by the drainage tank 300 according to the temperature detection result. For example, the safe temperature difference threshold can also be 20°C.

[0070] In one embodiment, the temperature control cycle control method further includes: Acquire a first temperature of an area near the first pair of joints 202 of the cooling tube assembly 20 and a second temperature of an area near the second pair of joints 204 of the cooling tube assembly 20; comparing the first temperature and the second temperature; If the first temperature is greater than the second temperature, the second control valve 950 is controlled to connect the second water outlet pipe group 920 and the drain pipe 700, and the first control valve 930 is controlled to connect the first main water outlet pipe 912, so that the cooling medium flows into the cooling pipe group through the first main water outlet pipe 912 and the first water outlet branch pipe 914 and the first joint 202, and is discharged from the drain pipe 700 through the second water outlet pipe group 920 and the second control valve 950; If the first temperature is lower than the second temperature, the second control valve 950 is controlled to connect the drain pipe 940 and the drain pipe 700, and the first control valve 730 is controlled to connect the second main water outlet pipe 924, so that the cooling medium passes through the second main water outlet pipe 922 and the second water outlet branch pipe 924 and flows into the cooling pipe group 20 through the second joint 204, and is discharged from the drain pipe 700 through the first water outlet pipe group 910 and the drain pipe 940.
