Description

Technical Field

[0001] The present application belongs to the technical field of drying equipment, and more specifically, to a temperature control device and a drying system. Background Art

[0002] Industrial dryers are a common type of equipment in industrial production processes. Currently, some industrial dryers use a heat pump structure for heating. However, the amount of refrigerant actually involved in the work of the existing heat pump structure of the industrial dryer cannot be adjusted. That is, under normal circumstances, all refrigerants in the system of the temperature control device will be fully involved in the work at all times, which limits the regulation efficiency of the output heat of the condenser and the operating reliability of the temperature control device under more extreme conditions. Summary of the invention

[0003] The purpose of the present application is to provide a temperature control device and a drying system to solve the technical problem of low efficiency in regulating the output heat of the temperature control device in the prior art.

[0004] To achieve the above purpose, the technical solution adopted in this application is:

[0005] In one aspect, a temperature control device is provided, the temperature control device comprising:

[0006] A compressor, the compressor comprising an air inlet end and an air outlet end;

[0007] An evaporator, the evaporator comprising an inlet end and an outlet end, the outlet end being connected to the air inlet end;

[0008] A heat supply passage, one end of which is connected to the air outlet, the heat supply passage comprising a condenser, and the condenser is used to output heat to the target area;

[0009] A main circulation passage, one end of which is connected to an end of the heat supply passage away from the air outlet, and the other end of which is connected to the inlet;

[0010] The auxiliary circulation passage has two ends connected to the main circulation passage, and the auxiliary circulation passage includes a liquid storage component, and the liquid storage component can store refrigerant.

[0011] Specifically, by setting an auxiliary circulation passage on the main circulation passage and setting the liquid storage component for storing refrigerant on the auxiliary circulation passage, the auxiliary circulation passage can store part of the refrigerant in stages, thereby changing the actual amount of refrigerant passing through the heating passage. On the one hand, it can realize rapid adjustment of the output heat of the condenser, and can capture or inject refrigerant according to the temperature state of the target area to achieve efficient control of the temperature of the target area; on the other hand, it can enable the temperature control device to be applied to more severe external environment scenes, thereby improving the versatility of the temperature control device; on the other hand, it can adjust the air pressure of the compressor more significantly and faster, thereby stabilizing the refrigerant pressure of the temperature control device, thereby improving the operating reliability of the temperature control device. Furthermore, when the required temperature of the target area is very low and the ambient temperature of the application scenario is also very low, the condenser needs to output less heat to the target area, that is, the heat exchange amount of the condenser is small. At this time, the storage amount of the refrigerant is increased by the liquid storage component, and the actual amount of refrigerant passing through the condenser can be quickly reduced, thereby significantly reducing the heat exchange amount of the condenser, thereby not only meeting the lower temperature demand of the target area, but also enabling the temperature control device to operate reliably in application scenarios with lower ambient temperatures; when the required temperature of the target area is very high and the ambient temperature of the application scenario is also very high, the condenser needs to output more heat to the target area. At this time, the storage amount of the refrigerant is reduced by the liquid storage component, and the actual amount of refrigerant passing through the condenser can be quickly increased, thereby significantly increasing the heat exchange amount of the condenser, thereby not only meeting the higher temperature demand of the target area, but also enabling the temperature control device to operate reliably in application scenarios with higher ambient temperatures.

[0012] As an embodiment, the liquid storage assembly includes a first liquid reservoir, a first control valve and a second control valve, the first control valve is arranged on a side of the first liquid reservoir away from the inlet end, the second control valve is arranged on a side of the first liquid reservoir close to the inlet end, and the first liquid reservoir is used to store refrigerant.

[0013] Specifically, by respectively arranging the first control valve and the second control valve on both sides of the first liquid reservoir, the conduction control between the first liquid reservoir and the main circulation passage can be reliably realized, thereby controlling the increase or decrease of the refrigerant storage amount of the first liquid reservoir, thereby realizing effective control of the actual refrigerant amount flowing through the condenser. Further, when it is necessary to increase the actual refrigerant amount flowing through the condenser, the opening of the first control valve is adjusted to be smaller than the opening of the second control valve, or the first control valve is directly closed and the second control valve is opened, so that the refrigerant in the first liquid reservoir is injected into the main circulation passage, thereby realizing the regulation of the output heat of the condenser; when it is necessary to reduce the actual refrigerant amount flowing through the condenser, the opening of the first control valve is adjusted to be larger than the opening of the second control valve, or the first control valve is directly opened and the second control valve is closed, so that the first liquid reservoir captures and stores the refrigerant in the main circulation passage, thereby realizing the regulation of the output heat of the condenser.

[0014] As an embodiment, the main circulation passage is provided with a heat rejection condenser.

[0015] Specifically, by arranging the heat rejection condenser in the main circulation passage, the refrigerant that has not fully released heat and condensed in the heat supply passage can be subjected to secondary heat rejection condensation, thereby improving the reliability of the refrigerant heat rejection condensation, thereby improving the operational effectiveness of the temperature control device. Furthermore, although the temperature control device is provided with the auxiliary circulation passage for changing the actual amount of refrigerant passing through the heat supply passage, which effectively improves the matching degree between the amount of refrigerant and the operating conditions and the output heat, there is still a situation of excessive refrigerant at certain stages during the dynamic adjustment of the amount of refrigerant. By arranging the heat rejection condenser, the state of the refrigerant can be adjusted more efficiently during the dynamic adjustment of the amount of refrigerant, thereby improving the operational stability of the temperature control device.

[0016] As an embodiment, the main circulation passage includes a first main passage and a second main passage, the auxiliary circulation passage is connected in parallel with the second main passage, and the heat rejection condenser is arranged in the first main passage.

[0017] Specifically, by arranging the heat rejection condenser on the first main passage, all the refrigerant flowing through the heating passage can flow through the heat rejection condenser, ensuring that the heat rejection condenser can perform secondary heat release on all the refrigerant, thereby improving the effectiveness of the heat rejection condenser in regulating the temperature control device.

[0018] As an embodiment, the heating passage includes a first heating passage and a second heating passage, and the condenser includes a first condenser and a second condenser, one end of the first heating passage is connected to the air outlet, and the other end of the first heating passage is connected to the main circulation passage, and the first condenser is arranged in the first heating passage, and the first condenser is used to output heat to a first target area; one end of the second heating passage is connected to the air outlet, and the other end of the second heating passage is connected to the main circulation passage, and the second condenser is arranged in the second heating passage, and the second condenser is used to output heat to a second target area.

[0019] Specifically, by setting the first heating passage and the second heating passage, one compressor is matched with two heating passages to work, which can not only fully utilize the processing capacity of the compressor, but also improve the use flexibility of the temperature control device, so that the temperature control device can control the temperature of multiple different target areas.

[0020] As an embodiment, the temperature control device includes a first switching passage, one end of the first switching passage is connected to a side of the first condenser away from the air outlet end, the other end of the first switching passage is connected to a side of the second condenser close to the air outlet end, and the first switching passage includes a first switching solenoid valve, which can control the refrigerant flow of the first switching passage.

[0021] Specifically, by setting the first switching passage connected to the downstream of the first condenser and the upstream of the second condenser, the first switching solenoid valve on the first switching passage is used to realize the conduction or isolation between the downstream of the first condenser and the upstream of the second condenser. When the output heat required by the second condenser is lower than the output heat required by the first condenser, the first switching passage is used to form a series structure between the first condenser and the second condenser, so that the refrigerant discharged from the compressor can flow through the first condenser and the second condenser in sequence, which can not only meet the different output heat requirements of the first condenser and the second condenser, but also enable the refrigerant to have more sufficient heat exchange, thereby improving the utilization rate of the energy carried by the refrigerant, thereby helping to improve the energy efficiency of the temperature control device, as well as improve the adjustment flexibility and adaptability of the temperature control device for different application scenarios. Furthermore, the refrigerant discharged from the compressor flows through the first condenser and the second condenser in sequence, and the refrigerant undergoes a first heat exchange in the first condenser. The first condenser obtains relatively large amounts of heat and outputs relatively high amounts of heat to the outside. These higher amounts of heat output are used to meet the temperature requirements of the first target area. At the same time, the refrigerant temperature drops for the first time. After the first temperature drop, the refrigerant enters the second condenser and undergoes a second heat exchange in the second condenser. The second condenser obtains relatively small amounts of heat and outputs relatively low amounts of heat to the outside. These lower amounts of heat output are used to meet the temperature requirements of the second target area. At the same time, the refrigerant temperature drops for the second time. During the entire process, the temperature control device not only meets the output heat requirements of the first condenser and the second condenser, but also fully utilizes the refrigerant energy, thereby improving the energy efficiency of the temperature control device.

[0022] As an embodiment, the temperature control device also includes a second switching passage, one end of the second switching passage is connected to the side of the second condenser away from the air outlet end, the other end of the second switching passage is connected to the side of the first condenser close to the air outlet end, and the second switching passage includes a second switching solenoid valve, and the second switching solenoid valve can control the refrigerant flow of the second switching passage.

[0023] Specifically, by setting the second switching passage connected to the downstream of the second condenser and the upstream of the first condenser, the second switching solenoid valve on the second switching passage is used to realize the connection or isolation between the downstream of the second condenser and the upstream of the first condenser. When the output heat required by the first condenser is lower than the output heat required by the second condenser, the second switching passage is used to form a series structure between the second condenser and the first condenser, so that the refrigerant discharged by the compressor can flow through the second condenser and the first condenser in sequence, which can not only meet the different output heat requirements of the first condenser and the second condenser, but also enable the refrigerant to have a more sufficient heat exchange, improve the utilization rate of the energy carried by the refrigerant, thereby helping to improve the energy efficiency of the temperature control device, and improve the adjustment flexibility and adaptability of the temperature control device for different application scenarios. At the same time, the first switching passage and the second switching passage are set, so that the connection relationship between the first condenser and the second condenser is more flexible, and then the use state of the temperature control device is more flexible, which is conducive to the temperature control device to better meet the use requirements of different application scenarios and effectively improve the versatility of the temperature control device. Furthermore, the refrigerant discharged from the compressor flows through the second condenser and the first condenser in sequence, and the refrigerant undergoes a first heat exchange in the second condenser. The second condenser obtains relatively large amounts of heat and outputs relatively high amounts of heat to the outside. These higher amounts of heat output are used to meet the temperature requirements of the second target area. At the same time, the refrigerant temperature drops for the first time. After the first temperature drop, the refrigerant enters the first condenser and undergoes a second heat exchange in the first condenser. The first condenser obtains relatively small amounts of heat and outputs relatively low amounts of heat to the outside. These lower amounts of heat output are used to meet the temperature requirements of the first target area. At the same time, the refrigerant temperature drops for the second time. During the entire process, the temperature control device not only meets the output heat requirements of the first condenser and the second condenser, but also fully utilizes the refrigerant energy, thereby improving the energy efficiency of the temperature control device.

[0024] As an embodiment, the temperature control device also includes a reflux passage, one end of the reflux passage is connected to an end of the heat supply passage away from the air outlet, the other end of the reflux passage is connected to the inlet end, and the reflux passage is provided with a reflux solenoid valve, which is used to control the on and off of the reflux passage.

[0025] Specifically, by providing the reflux passage between the heat supply passage and the evaporator, the refrigerant can directly reflux from the heat supply passage to the evaporator without flowing through the main circulation passage, thereby improving the circulation efficiency of the refrigerant. Furthermore, when the refrigerant achieves sufficient heat release and condensation in the heat supply passage, the refrigerant directly refluxes to the evaporator through the reflux passage and skips the main circulation passage, which helps to improve the circulation efficiency of the refrigerant.

[0026] As an embodiment, the reflux passage includes a reflux main branch, a first reflux branch and a second reflux branch, and the reflux solenoid valve includes a first reflux solenoid valve and a second reflux solenoid valve, one end of the first reflux branch is connected to the side of the first heating passage away from the air outlet, the other end of the first reflux branch is connected to one end of the reflux main branch, the first reflux solenoid valve is arranged in the first reflux branch, and the first reflux solenoid valve is used to control the on-off of the first reflux branch; one end of the second reflux branch is connected to the side of the second heating passage away from the air outlet, the other end of the second reflux branch is connected to the reflux main branch used to connect to one end of the first reflux branch, the second reflux solenoid valve is arranged in the second reflux branch, and the second reflux solenoid valve is used to control the on-off of the second reflux branch; the end of the reflux main branch away from the first reflux branch is connected to the inlet end.

[0027] Specifically, by providing the first return branch and the second return branch that can be individually connected, the return direction of the refrigerant in the first heating passage and the second heating passage can be independently controlled, which helps to improve the flexibility of the return direction of the refrigerant in the first heating passage and the second heating passage.

[0028] On the other hand, a drying system is provided, which includes a box and any one of the temperature control devices described above, wherein the condenser is arranged in the box.

[0029] Specifically, by arranging the condenser in the box, the condenser is utilized to stably and reliably transfer heat to the workpieces in the box, thereby effectively improving the drying efficiency of the workpieces.

[0030] The beneficial effects of the temperature control device and drying system provided by the present application are:

[0031] By providing an auxiliary circulation passage on the main circulation passage, and providing the liquid storage component for storing refrigerant on the auxiliary circulation passage, the auxiliary circulation passage can store part of the refrigerant in stages, thereby changing the amount of refrigerant actually passing through the heating passage. On the one hand, it can realize rapid adjustment of the output heat of the condenser, and can capture or inject refrigerant according to the temperature state of the target area to realize efficient control of the temperature of the target area; on the other hand, it can enable the temperature control device to be applied to more severe external environment scenes, thereby improving the versatility of the temperature control device; on the other hand, it can adjust the air pressure of the compressor to a greater extent and faster, thereby stabilizing the refrigerant pressure of the temperature control device, thereby improving the operating reliability of the temperature control device.

In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0050] The present application embodiment provides a temperature control device, such as Figure 1 and Figure 2 As shown, the temperature control device includes a compressor 1, an evaporator 2, a heating passage 3, a main circulation passage 4 and an auxiliary circulation passage 5, the compressor 1 includes an air inlet end 11 and an air outlet end 12; the evaporator 2 includes an inlet end 21 and an outlet end 22, and the outlet end 22 is connected to the air inlet end 11; one end of the heating passage 3 is connected to the air outlet end 12, and the heating passage 3 includes a condenser, and the condenser is used to output heat to the target area; one end of the main circulation passage 4 is connected to an end of the heating passage 3 away from the air outlet end 12, and the other end of the main circulation passage 4 is connected to the inlet end 21; both ends of the auxiliary circulation passage 5 are connected to the main circulation passage 4, and the auxiliary circulation passage 5 includes a liquid storage component 51, which can store refrigerant.

[0051] Specifically, by setting an auxiliary circulation passage 5 on the main circulation passage 4 and setting a liquid storage component 51 for storing refrigerant on the auxiliary circulation passage 5, the auxiliary circulation passage 5 can store part of the refrigerant in stages, thereby changing the actual amount of refrigerant passing through the heating passage 3. On the one hand, it can realize rapid adjustment of the output heat of the condenser, and can capture or inject refrigerant according to the temperature state of the target area to achieve efficient control of the temperature of the target area; on the other hand, it can enable the temperature control device to be applied to more severe external environment scenes, thereby improving the versatility of the temperature control device; on the other hand, it can adjust the air pressure of the compressor 1 to a greater extent and faster, thereby stabilizing the refrigerant pressure of the temperature control device, thereby improving the operating reliability of the temperature control device. Furthermore, when the required temperature of the target area is very low and the ambient temperature of the application scenario is also very low, the condenser needs to output less heat to the target area, that is, the heat exchange amount of the condenser is small. At this time, by increasing the storage amount of the refrigerant through the liquid storage component 51, the actual amount of refrigerant passing through the condenser can be quickly reduced, and then the heat exchange amount of the condenser can be significantly reduced, thereby not only meeting the lower temperature demand of the target area, but also enabling the temperature control device to operate reliably in the application scenario with a lower ambient temperature; when the required temperature of the target area is very high and the ambient temperature of the application scenario is also very high, the condenser needs to output more heat to the target area. At this time, by reducing the storage amount of the refrigerant through the liquid storage component 51, the actual amount of refrigerant passing through the condenser can be quickly increased, and then the heat exchange amount of the condenser can be significantly increased, thereby not only meeting the higher temperature demand of the target area, but also enabling the temperature control device to operate reliably in the application scenario with a higher ambient temperature.

[0052] In one embodiment, if Figure 1 and Figure 2 As shown, the auxiliary circulation passage 5 further includes a capillary tube 52 , which is disposed on a side of the liquid storage component 51 close to the inlet end 21 .

[0053] In one embodiment, if Figure 1 and Figure 2 As shown, the liquid storage assembly 51 includes a first liquid reservoir 511, a first control valve 512 and a second control valve 513. The first control valve 512 is arranged on a side of the first liquid reservoir 511 away from the inlet end 21, and the second control valve 513 is arranged on a side of the first liquid reservoir 511 close to the inlet end 21. The first liquid reservoir 511 is used to store refrigerant.

[0054] Specifically, by respectively arranging the first control valve 512 and the second control valve 513 on both sides of the first liquid reservoir 511, the conduction control between the first liquid reservoir 511 and the main circulation passage 4 can be reliably achieved, thereby controlling the increase or decrease of the refrigerant storage amount of the first liquid reservoir 511, thereby achieving effective control of the actual amount of refrigerant flowing through the condenser. Furthermore, when it is necessary to increase the actual amount of refrigerant flowing through the condenser, the opening of the first control valve 512 is adjusted to be smaller than the opening of the second control valve 513, or the first control valve 512 is directly closed and the second control valve 513 is opened, so that the refrigerant in the first liquid reservoir 511 is injected into the main circulation passage 4, thereby achieving the output heat adjustment of the condenser; when it is necessary to reduce the actual amount of refrigerant flowing through the condenser, the opening of the first control valve 512 is adjusted to be larger than the opening of the second control valve 513, or the first control valve 512 is directly opened and the second control valve 513 is closed, so that the first liquid reservoir 511 captures and stores the refrigerant in the main circulation passage 4, thereby achieving the output heat adjustment of the condenser.

[0055] In one embodiment, if Figure 1 and Figure 2 As shown, the liquid storage assembly 51 further includes a first filter 514, which is disposed between the first liquid storage tank 511 and the second control valve 513. In a specific implementation, the main circulation passage 4 is provided with a second filter 45, which is connected in parallel with the auxiliary circulation passage 5.

[0056] In one embodiment, if Figure 2 As shown, the main circulation passage 4 is provided with a heat rejection condenser 41. By providing the heat rejection condenser 41 in the main circulation passage 4, the refrigerant that has not been fully heat-dissipated and condensed in the heating passage 3 can be subjected to secondary heat rejection and condensation, thereby improving the reliability of the heat rejection and condensation of the refrigerant, thereby improving the operational effectiveness of the temperature control device. Furthermore, although the temperature control device is provided with an auxiliary circulation passage 5 for changing the actual amount of refrigerant passing through the heating passage 3, which effectively improves the matching degree between the amount of refrigerant and the operating conditions and the output heat, in the process of dynamic adjustment of the amount of refrigerant, there is still a situation where the amount of refrigerant is excessive at certain stages. By providing the heat rejection condenser 41, the state of the refrigerant can be adjusted more efficiently in the process of dynamic adjustment of the amount of refrigerant, thereby improving the operational stability of the temperature control device.

[0057] In one embodiment, if Figure 2As shown, the main circulation passage 4 includes a first main passage 42 and a second main passage 43 , the auxiliary circulation passage 5 is connected in parallel with the second main passage 43 , and the heat rejection condenser 41 is arranged in the first main passage 42 .

[0058] Specifically, by arranging the heat rejection condenser 41 on the first main passage 42, all the refrigerant flowing through the heating passage 3 can flow through the heat rejection condenser 41, ensuring that the heat rejection condenser 41 can perform secondary heat release on all the refrigerant, thereby improving the effectiveness of the heat rejection condenser 41 in regulating the temperature control device.

[0059] In one embodiment, if Figure 2 As shown, the main circulation passage 4 includes a second liquid reservoir 44 , which is arranged in the first main passage 42 , and the second liquid reservoir 44 is located on a side of the heat rejection condenser 41 away from the heat supply passage 3 .

[0060] In one embodiment, if Figure 2 As shown, the second filter 45 is disposed in the second main passage 43 , and the second main passage 43 is further provided with a first expansion valve 46 . The first expansion valve 46 is located on a side of the second filter 45 close to the inlet end 21 .

[0061] In one embodiment, if Figure 2 As shown, the heat supply passage 3 includes a first heat supply passage 31 and a second heat supply passage 32, and the condenser includes a first condenser 311 and a second condenser 321. One end of the first heat supply passage 31 is connected to the air outlet end 12, and the other end of the first heat supply passage 31 is connected to the main circulation passage 4. The first condenser 311 is arranged in the first heat supply passage 31, and the first condenser 311 is used to output heat to the first target area 101; one end of the second heat supply passage 32 is connected to the air outlet end 12, and the other end of the second heat supply passage 32 is connected to the main circulation passage 4, and the second condenser 321 is arranged in the second heat supply passage 32, and the second condenser 321 is used to output heat to the second target area 102;

[0062] Specifically, by setting the first heating passage 31 and the second heating passage 32, one compressor 1 is matched with two heating passages 3 to work, which can not only fully utilize the processing capacity of the compressor 1, but also improve the use flexibility of the temperature control device, so that the temperature control device can control the temperature of multiple different target areas.

[0063] In one embodiment, if Figure 2As shown, the first heat supply passage 31 includes two first condensers 311, which are arranged in parallel, and the second heat supply passage 32 includes two second condensers 321, which are arranged in parallel. Specifically, by arranging two parallel first condensers 311 and two parallel second condensers 321, the first heat supply passage 31 or the second heat supply passage 32 can simultaneously perform heating control on two different positions of the target area, thereby making the temperature of different positions of the target area more uniform.

[0064] Of course, in other embodiments, the temperature control device may also include a third heating passage or even a fourth heating passage, that is, the number of heating passages may be more than three, such as four or five or six, etc. During application, the specific number of heating passages 3 may be determined according to the number of target areas, so that each heating passage 3 corresponds to a target area, thereby enabling the temperature control device to serve multiple target areas and output heat to multiple target areas.

[0065] In one embodiment, if Figure 2 As shown, the temperature control device includes a first switching passage 6, one end of the first switching passage 6 is connected to the side of the first condenser 311 away from the air outlet end 12, and the other end of the first switching passage 6 is connected to the side of the second condenser 321 close to the air outlet end 12. The first switching passage 6 includes a first switching solenoid valve 61, and the first switching solenoid valve 61 can control the refrigerant flow of the first switching passage 6.

[0066] Specifically, by setting a first switching passage 6 connected to the downstream of the first condenser 311 and the upstream of the second condenser 321, the first switching solenoid valve 61 on the first switching passage 6 is used to realize the conduction or isolation of the downstream of the first condenser 311 and the upstream of the second condenser 321. When the output heat required by the second condenser 321 is lower than the output heat required by the first condenser 311, the first switching passage 6 is used to form a series structure between the first condenser 311 and the second condenser 321, so that the refrigerant discharged from the compressor 1 can flow through the first condenser 311 and the second condenser 321 in sequence, which can not only meet the different output heat requirements of the first condenser 311 and the second condenser 321, but also enable the refrigerant to have a more sufficient heat exchange, thereby improving the utilization rate of the energy carried by the refrigerant, thereby helping to improve the energy efficiency of the temperature control device, as well as improve the adjustment flexibility and adaptability of the temperature control device for different application scenarios. Furthermore, the refrigerant discharged from the compressor 1 flows through the first condenser 311 and the second condenser 321 in sequence, and the refrigerant undergoes a first heat exchange in the first condenser 311. The first condenser 311 obtains relatively large amounts of heat, and outputs relatively high amounts of heat to the outside. These relatively high amounts of heat output are used to meet the temperature requirement of the first target area 101, and at the same time, the refrigerant temperature drops for the first time. After the first temperature drop, the refrigerant enters the second condenser 321 and undergoes a second heat exchange in the second condenser 321. The second condenser 321 obtains relatively small amounts of heat, and outputs relatively low amounts of heat to the outside. These relatively low amounts of heat output are used to meet the temperature requirement of the second target area 102, and at the same time, the refrigerant temperature drops for the second time. During the entire process, the temperature control device not only meets the output heat requirements of the first condenser 311 and the second condenser 321, but also fully utilizes the refrigerant energy, thereby improving the energy efficiency of the temperature control device.

[0067] In one embodiment, if Figure 2 As shown, the temperature control device also includes a second switching passage 7, one end of the second switching passage 7 is connected to the side of the second condenser 321 away from the air outlet end 12, and the other end of the second switching passage 7 is connected to the side of the first condenser 311 close to the air outlet end 12. The second switching passage 7 includes a second switching solenoid valve 71, and the second switching solenoid valve 71 can control the refrigerant flow of the second switching passage 7.

[0068] Specifically, by setting up a second switching passage 7 connected to the downstream of the second condenser 321 and the upstream of the first condenser 311, the second switching solenoid valve 71 on the second switching passage 7 is used to realize the conduction or isolation between the downstream of the second condenser 321 and the upstream of the first condenser 311. When the output heat required by the first condenser 311 is lower than the output heat required by the second condenser 321, the second switching passage 7 is used to form a series structure between the second condenser 321 and the first condenser 311, so that the refrigerant discharged from the compressor 1 can flow through the second condenser 321 and the first condenser 311 in sequence, which can not only meet the different output heat requirements of the first condenser 311 and the second condenser 321, but also enable the refrigerant to have a more sufficient heat exchange, thereby improving the utilization rate of the energy carried by the refrigerant, thereby helping to improve the energy efficiency of the temperature control device, as well as improve the adjustment flexibility and adaptability of the temperature control device for different application scenarios. The first switching passage 6 and the second switching passage 7 are provided at the same time, so that the connection relationship between the first condenser 311 and the second condenser 321 is more flexible, thereby making the use state of the temperature control device more flexible, which is conducive to the temperature control device being able to better meet the use requirements of different application scenarios and effectively improve the versatility of the temperature control device. Furthermore, the refrigerant discharged from the compressor 1 flows through the second condenser 321 and the first condenser 311 in sequence, and the refrigerant undergoes a first heat exchange in the second condenser 321. The second condenser 321 obtains relatively large amounts of heat, and outputs relatively high amounts of heat to the outside. These relatively high amounts of heat output are used to meet the temperature requirements of the second target area 102. At the same time, the refrigerant temperature drops for the first time. After the first temperature drop, the refrigerant enters the first condenser 311 and undergoes a second heat exchange in the first condenser 311. The first condenser 311 obtains relatively small amounts of heat, and outputs relatively low amounts of heat to the outside. These relatively low amounts of heat output are used to meet the temperature requirements of the first target area 101. At the same time, the refrigerant temperature drops for the second time. During the entire process, the temperature control device not only meets the output heat requirements of the first condenser 311 and the second condenser 321, but also fully utilizes the refrigerant energy, thereby improving the energy efficiency of the temperature control device.

[0069] In one embodiment, if Figure 2 As shown, the first heating passage 31 also includes a first heating solenoid valve 312, which is arranged between the first condenser 311 and the air outlet end 12, and the first heating solenoid valve 312 can disconnect the connection between the air outlet end 12 and the first condenser 311; the second heating passage 32 also includes a second heating solenoid valve 322, which is arranged between the second condenser 321 and the air outlet end 12, and the second heating solenoid valve 322 can disconnect the connection between the air outlet end 12 and the second condenser 321.

[0070] Specifically, on the one hand, by setting the first heating solenoid valve 312 and the second heating solenoid valve 322 that can control the on and off of the first heating passage 31 and the second heating passage 32, the refrigerant flow through the first condenser 311 and the second condenser 321 can be controlled, thereby achieving effective control of the output heat of the first condenser 311 and the second condenser 321. On the other hand, by setting the first heating solenoid valve 312 on the side of the first condenser 311 close to the gas outlet end 12, and setting the second heating solenoid valve 322 on the side of the second condenser 321 close to the gas outlet end 12, the refrigerant communication between the first condenser 311, the second condenser 321 and the compressor 1 can be more effectively isolated, so that the amount of refrigerant flowing through the first condenser 311 and the second condenser 321 is more accurate and controllable.

[0071] In one embodiment, if Figure 2 As shown, the first heat supply passage 31 also includes a third heat supply solenoid valve 313, which is located on the side of the first condenser 311 away from the air outlet end 12, and there is a first node 314 between the first condenser 311 and the third heat supply solenoid valve 313, and one end of the first switching passage 6 is connected to the first node 314; there is a second node 324 between the second condenser 321 and the second heat supply solenoid valve 322, and the other end of the first switching passage 6 is connected to the second node 324; the second heat supply passage 32 also includes a fourth heat supply solenoid valve 323, which is located on the side of the second condenser 321 away from the air outlet end 12, and there is a third node 325 between the second condenser 321 and the fourth heat supply solenoid valve 323, and one end of the second switching passage 7 is connected to the third node 325; there is a fourth node 315 between the first condenser 311 and the first heat supply solenoid valve 312, and the other end of the second switching passage 7 is connected to the fourth node 315.

[0072] Specifically, on one hand, by connecting the first switching passage 6 to the first node 314 and the second node 324, the first switching solenoid valve 61 cooperates with the second heating solenoid valve 322 and the third heating solenoid valve 313, so that the first condenser 311 and the second condenser 321 can be connected in series more reliably, so that the refrigerant can reliably flow through the first condenser 311 and the second condenser 321 in sequence and perform heat exchange, effectively improving the energy utilization rate of the refrigerant. On the other hand, by connecting the second switching passage 7 to the third node 325 and the fourth node 315, the second switching solenoid valve 71 cooperates with the first heating solenoid valve 312 and the fourth heating solenoid valve 323, so that the second condenser 321 and the first condenser 311 can be connected in series more reliably, so that the refrigerant can reliably flow through the second condenser 321 and the first condenser 311 in sequence and perform heat exchange, effectively improving the energy utilization rate of the refrigerant. Furthermore, under normal use conditions, the first switching solenoid valve 61 and the second switching solenoid valve 71 are closed, the first heat supply passage 31 and the second heat supply passage 32 are connected in parallel, the first heat supply passage 31 and the second heat supply passage 32 divert the refrigerant discharged from the compressor 1, and the refrigerant only flows through one of the first condenser 311 and the second condenser 321; when the output heat required by the second condenser 321 is lower than the output heat required by the first condenser 311, the second heating solenoid valve 322 and the third heating solenoid valve 313 can be closed, and the first switching solenoid valve 61 can be opened at the same time, so that the first node 314 is connected to the second node 324. At this time, the first condenser 311 and the second condenser 321 form a series structure, and the refrigerant discharged from the compressor 1 can flow through the first condenser 311 and the second condenser 321 in sequence, which can satisfy the first condenser 311 and the second condenser 321 has different output heat requirements, and can make the refrigerant more fully heat exchanged, improve the utilization rate of the energy carried by the refrigerant, thereby helping to improve the energy efficiency of the temperature control device; when the output heat required by the first condenser 311 is lower than the output heat required by the second condenser 321, the first heating solenoid valve 312 and the fourth heating solenoid valve 323 can be closed, and the second switching solenoid valve 71 can be opened at the same time, so that the third node 325 is connected to the fourth node 315. At this time, the second condenser 321 and the first condenser 311 form a series structure, and the refrigerant discharged from the compressor 1 can flow through the second condenser 321 and the first condenser 311 in turn, which can not only meet the different output heat requirements of the first condenser 311 and the second condenser 321, but also make the refrigerant more fully heat exchanged, improve the utilization rate of the energy carried by the refrigerant, thereby helping to improve the energy efficiency of the temperature control device.

[0074] Specifically, by providing a reflux passage 8 between the heating passage 3 and the evaporator 2, the refrigerant can directly reflux from the heating passage 3 to the evaporator 2 without flowing through the main circulation passage 4, thereby improving the circulation efficiency of the refrigerant. Furthermore, when the refrigerant achieves sufficient heat release and condensation in the heating passage 3, the refrigerant directly refluxes to the evaporator 2 through the reflux passage 8 and skips the main circulation passage 4, which helps to improve the circulation efficiency of the refrigerant.

[0076] Specifically, by providing the first return branch 82 and the second return branch 83 which can be separately connected, the return direction of the refrigerant in the first heating passage 31 and the second heating passage 32 can be independently controlled, which helps to improve the flexibility of the return direction of the refrigerant in the first heating passage 31 and the second heating passage 32.

Specifically, by arranging the condenser in the box 100, the condenser is used to stably and reliably transfer heat to the workpiece in the box 100, thereby effectively improving the drying efficiency of the workpiece. In the specific implementation process, the drying system can be applied to the production of the shoe industry.
