Description

Technical Field

[0001] This invention relates to the field of industrial temperature control technology, and more particularly to an industrial temperature control system. Background Technology

[0002] A refrigeration and heating temperature control system is a device or system that can simultaneously achieve refrigeration, heating, and precise temperature control. It is widely used in industrial and scientific research fields requiring strict temperature control. Its core function is to maintain the temperature of a target object or environment within a set range through heating and cooling modules.

[0003] To address the issue of slow switching speed between cooling and heating in current air conditioning temperature control systems, existing technology incorporates a heating plate within the air duct to heat the air and deliver hot air. When cooling is required, cold water plates positioned on both sides of the heating plate converge to form a cylindrical coolant flow channel, enclosing the heating plate between the cylindrical cold water plates and introducing coolant into the cold water plates, thus achieving rapid switching between cooling and heating.

[0004] However, the applicant has found that the prior art has at least the following problems:

[0005] In existing technologies, when switching from heating to cooling, the residual heat of the heating plate causes the coolant to be heated rapidly, reducing the cooling rate. Similarly, when switching from cooling to heating, the lower temperature of the cooling plate causes it to absorb a large amount of heat generated by the heating plate, reducing the heating rate. Therefore, in existing technologies, temperature control feedback is not rapid enough during temperature conversion. Summary of the Invention

[0006] In view of this, the purpose of this invention is to provide an industrial temperature control system to solve the problem of insufficient temperature control feedback during temperature transitions.

[0007] To achieve the above objectives, the present invention provides an industrial temperature control system, including a ducted air supply module, wherein a filter, a blower, a temperature conversion unit, and an air conditioning unit are sequentially arranged within the duct, comprising:

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0040] like Figures 1 to 8As shown in the figure, a specific embodiment of the present invention provides an industrial temperature control system, including a duct air supply module 100 for cooling or heating air and supplying it to a target environment through a duct. The duct contains a filter 101, a blower 102, a temperature conversion unit 103, and an air conditioning unit 104 arranged sequentially. The temperature conversion unit 103 includes a rotating base 201 installed inside the duct. Guide rails are respectively formed on two adjacent surfaces of the rotating base 201. A heating component and a cooling component are respectively installed in the guide rails. The heating component includes at least one heating rod 302, and first water-passing plates 301 are respectively installed on both sides of the heating rod 302. The first water-passing plate 301 is arc-shaped, and when closed, it forms a cylinder that encloses the heating rod 302. The refrigeration component includes two sets of second water-passing plates 401, which are also arc-shaped and form a cylinder when closed. The first water-passing plate 301 and the second water-passing plate 401 are set at 90°. During refrigeration, the two sets of second water-passing plates 401 are separated and vertically arranged on the air passage of the pipe, while the two sets of first water-passing plates 301 are closed and attached to the bottom wall of the pipe. During heating, the rotating seat 201 rotates 90°, the two sets of first water-passing plates 301 are separated and vertically arranged on the air passage of the pipe, while the two sets of second water-passing plates 401 are closed and attached to the bottom wall of the pipe.

[0041] The control module 107 is used to control the flow direction of the coolant based on the temperature of the coolant when it flows through the temperature conversion unit 103 during the switching between cooling and heating.

[0042] Coolant storage unit 105 is used to store coolant for refrigeration;

[0043] The heat recovery storage unit 106 is used to recover the coolant heated by waste heat when switching from cooling to heating.

[0044] During cooling, coolant is introduced into the second water-passing plate 401 and flows through the first water-passing plate 301. If the temperature of the coolant flowing out of the first water-passing plate 301 is higher than the high temperature threshold, it is introduced into the waste heat recovery storage unit 106; otherwise, it enters the coolant storage unit 105. During heating, coolant heated by waste heat is introduced into the first water-passing plate 301 and flows through the second water-passing plate 401. If the temperature of the coolant flowing out of the second water-passing plate 401 is lower than the low temperature threshold, it is introduced into the coolant storage unit 105; otherwise, it enters the heat recovery storage unit 106.

[0045] When in use, if cooling is required in an industrial area, the second water-passing plate 401 of the refrigeration unit is vertically deployed in the air duct, and the coolant in the coolant storage unit 105 is introduced into the second water-passing plate 401. The second water-passing plate 401 cools the air flowing through it and sends it to the air conditioning unit 104 via the blower 102. The air conditioning unit 104 adjusts the airflow direction, allowing the cold air to enter the workplace for cooling. The coolant in the water plate 401 flows through the first water plate 301, and the temperature of the coolant flowing out of the first water plate 301 is monitored. If the temperature is higher than the high temperature threshold, it is introduced into the heat recovery storage unit 106. When it is necessary to switch from cooling to heating, the rotating seat 201 is driven to rotate 90°, so that the first water plate 301 is vertically unfolded in the air duct, and the second water plate 401 is closed into a cylinder and attached to the inner wall of the air duct. The heating rod 302 is energized for heating, and the heat recovery storage unit 106... The waste heat coolant in section 6 flows sequentially through the first water-passing plate 301 and the second water-passing plate 401. This not only helps the first water-passing plate 301 heat up quickly, reducing the absorption of heat radiation from the heating rod 302, but also heats up the second water-passing plate 401, which is at a lower temperature, reducing its impact on air cooling. When the temperature of the coolant flowing out of the second water-passing plate 401 is lower than the low temperature threshold, it is introduced into the coolant storage unit 105; otherwise, it is introduced into the heat recovery storage unit 106. Once the temperature of the second water-passing plate 401 is not lower than the air inlet temperature, the introduction of waste heat coolant is turned off. At this point, the cooling effect of the second water-passing plate 401 has been eliminated. During this process, not only can the heating and cooling processes be switched quickly, but the waste heat from the heating process can also be recovered. When switching from cooling to heating again, the waste heat is used to quickly heat up the cooling components at a low temperature, reducing their impact on the heating process. This improves the response speed of the temperature control system and reduces energy consumption.

[0046] In some optional specific embodiments, such as Figures 4 to 8 As shown, the first water-passing plate 301 is connected to a first connecting pipe 303 at both ends, and a first movable block 305 is connected to the end of the first connecting pipe 303. The first movable blocks 305 at both ends of the first water-passing plate 301 are adapted to connect the rotating seat 201 and the first connecting seat 304 respectively. The guide rail of the rotating seat 201 is provided with a first pair of interfaces 205 and a second pair of interfaces 206, which correspond to the two positions of the first water-passing plate 301 when it is closed and when it is unfolded. A flexible hose is connected between the first water-passing plate 301 and the first connecting seat 304. The first connecting seat 304 is provided with a first docking end 307 at both ends, and the first docking end 307 is adapted to connect a first water outlet 501 and a second water inlet 504 respectively. The first water outlet 501 is used to draw out the refrigerant during cooling, and the second water inlet 504 is used to introduce the waste heat coolant during heating.

[0047] In some optional specific embodiments, such as Figures 4 to 8 As shown, the second water-passing plate 401 is connected to two ends of a second connecting pipe 402, and the second connecting pipe 402 is connected to a second movable block 403. The second movable blocks 403 at both ends of the second water-passing plate 401 are connected to a rotating seat 201 and a second connecting seat 405, respectively. The guide rail of the rotating seat 201 is provided with a first pair of interfaces 205 and a second pair of interfaces 206, which correspond to the two positions of the second water-passing plate 401 when it is closed and when it is unfolded. A flexible hose is connected between the second water-passing plate 401 and the second connecting seat 405. The two ends of the second connecting seat 405 are provided with second docking ends 406, and the second docking ends 406 are adapted to be connected to a first water inlet 502 and a second water outlet 503, respectively. The first water inlet 502 is used to introduce refrigerant during refrigeration, and the second water outlet 503 is used to draw out residual heat coolant during heating.

[0048] In some optional specific embodiments, such as Figures 4 to 8 As shown, the first water outlet 501, the second water inlet 504 and the first docking end 307 are connected by pneumatic quick connectors, as are the second water outlet 503, the first water inlet 502 and the second docking end 406. When aligned, they are connected by pneumatic pressing, and when separated, they are closed and sealed respectively.

[0049] In some optional specific embodiments, such as Figures 4 to 8 As shown, the first movable block 305, the second movable block 403, the first interface 205, and the second interface 206 are connected by abutting valves. Taking the cooperation between the second interface 206 and the second movable block 403 as an example, the second movable block 403 has a partition cavity 4031, which is connected to the second connecting pipe 402. The partition cavity 4031 is connected to a moving cavity 4032, and the moving cavity 4032 is connected to an installation cavity 4034. A partition valve 4033 is adapted to be installed in the moving cavity 4032, and a stepped moving valve is adapted to be installed in the installation cavity 4034. A spring-loaded drive rod 4035 is connected between the stepped surface of the stepped moving cylinder 4037 and the mounting cavity 4034. A top rod 4036 is installed inside the stepped moving cylinder 4037 and is connected to the isolation valve 4033. A ball bearing 4038 is provided on the contact surface between the stepped moving cylinder 4037 and the guide rail. When the stepped moving cylinder 4037 is opposite to the guide rail, the isolation valve 4033 is in the moving cavity 4032 to achieve sealing. When the stepped moving cylinder 4037 is opposite to the second pair of interfaces 206, the isolation valve 4033 moves out of the moving cavity 4032 to achieve passage.

[0050] In some optional specific embodiments, such as Figures 4 to 8As shown, the second pair of interfaces 206 includes a docking cavity 2061 formed in the guide rail. The docking cavity 2061 is connected to a flow cavity 2062. A sealing ring 2063 is fitted into the docking cavity 2061. The sealing ring 2063 is connected to a support post 2064. The support post 2064 is connected to a valve 2065. The valve 2065 has multiple water flow holes 2066 arranged in an array. A spring rod is connected between the support post 2064 and the flow cavity 2062, so that the valve 2065 is pressed against the end of the flow cavity 2062 under normal conditions, and the water flow holes 2066 are sealed. When the second movable block 403 docks with the second pair of interfaces 206, the stepped moving cylinder 4037 pushes the sealing ring 2063 to move towards the flow cavity 2062, thereby making the two connected.

[0051] In some optional embodiments, the end of the stepped moving cylinder 4037 that contacts the sealing ring 2063 is provided with a bevel, so that when the second movable block 403 moves out of the second pair of interfaces 206, the stepped moving cylinder 4037 retracts into the mounting cavity 4034.

[0052] In some optional specific embodiments, such as Figure 4 As shown, the rotating seat 201 is connected to two rotating shafts 204 at both ends, and the rotating shafts 204 are powered by a rotating motor 202, which is fixedly installed outside the pipe.

[0053] In some optional specific embodiments, such as Figure 4 As shown, a pair of closing guide rails 203 are installed inside the pipe to hold and limit the first connecting pipe 303 and the second connecting pipe 402. Each closing guide rail 203 is formed by two guide rods connected together. The distance between the ends of the paired closing guide rails 203 is less than the distance between the connection points of the guide rods. A first elastic rod 306 is connected between the first movable blocks 305, and a second elastic rod 404 is connected between the second movable blocks 403, causing the first water-passing plate 301 and the second water-passing plate 401 to tend to separate. In use, the two sets of first water-passing plates 301 and two sets of second water-passing plates 401 tend to separate. The closing guide rails 203 control the closing and separation of the first water-passing plates 301 and the second water-passing plates 401 according to their positions.

[0054] In some optional embodiments, the control module 107 includes a temperature acquisition unit 1071 and an instruction generation unit 1072. The temperature acquisition unit 1071 is used to acquire the coolant temperature at the first outlet 501 and the second outlet 503. If the coolant temperature at the first outlet 501 is greater than the high temperature threshold, the instruction generation unit 1072 generates an instruction to introduce the coolant at the first outlet 501 into the heat recovery storage unit 106. If the coolant temperature at the second outlet 503 is lower than the low temperature threshold, the instruction generation unit 1072 generates an instruction to introduce the coolant at the second outlet 503 into the coolant storage unit 105.

[0055] The working principle of this invention is as follows: When cooling is required in an industrial environment, the second water-passing plate 401 of the cooling assembly is vertically deployed in the air duct, and the coolant in the coolant storage unit 105 is introduced into the second water-passing plate 401. The second water-passing plate 401 cools the air flowing through it, and the air is then sent to the air conditioning unit 104 by the blower 102. The air conditioning unit 104 adjusts the airflow direction, allowing the cold air to enter the workplace for cooling. The coolant flows through the second water-passing plate 401 into the first water-passing plate 301, and the temperature of the coolant flowing out of the first water-passing plate 301 is monitored. If the temperature is higher than the high-temperature threshold, it is introduced into the heat recovery storage unit 106. When it is necessary to switch from cooling to heating, the rotating seat 201 is driven to rotate 90°, so that the first water-passing plate 301 is vertically unfolded in the air duct, and the second water-passing plate 401 is closed into a cylinder and attached to the inner wall of the air duct. The heating rod 302 is energized to heat the system, and the heat recovery storage unit 106 is activated. The waste heat coolant in storage unit 106 flows sequentially through the first water-passing plate 301 and the second water-passing plate 401. This not only helps the first water-passing plate 301 heat up quickly, reducing the absorption of heat radiation from the heating rod 302, but also heats up the second water-passing plate 401, which is at a lower temperature, reducing its impact on air cooling. When the temperature of the coolant flowing out of the second water-passing plate 401 is lower than the low temperature threshold, it is introduced into the coolant storage unit 105; otherwise, it is introduced into the heat recovery storage unit 106. Once the temperature of the second water-passing plate 401 is not lower than the air inlet temperature, the introduction of waste heat coolant is turned off. At this point, the cooling effect of the second water-passing plate 401 has been eliminated. During this process, not only can the heating and cooling processes be switched quickly, but the waste heat in the heating process can also be recovered. When switching from cooling to heating in the next cycle, the waste heat is used to quickly heat up the cooling components at a low temperature, reducing their impact on the heating process. This improves the response speed of the temperature control system and reduces energy consumption.
