For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] Refer to the following Figure 1 A temperature regulation system according to some embodiments of the present application is described.

[0031] See also Figure 1 As shown, an embodiment of the present application provides a temperature regulation system, comprising: a heating and cooling component 1 and a circulating liquid supply component 2; wherein the heating and cooling component 1 comprises a compressor 101, a condenser 102, an evaporator 103, a first temperature sensor 104, a second temperature sensor 105 and a first pressure sensor 106, the evaporator 103 is formed with a first heat exchange channel and a second heat exchange channel, and the compressor 101, the condenser 102, and the first heat exchange channel are connected in sequence end to end via a pipeline to form a circulating refrigeration structure, and the first temperature sensor 104, the second temperature sensor 105 and the first pressure sensor 106 are sequentially arranged on the pipeline between the condenser 102 and the heat exchange channel;

[0032] The circulating liquid supply component 2 is connected to the second heat exchange channel, and the heating and cooling component 1 is used to cool or heat the liquid in the circulating liquid supply component 2. The circulating liquid supply component 2 is used to provide temperature-control liquid to the equipment to be temperature-controlled, such as equipment for preparing chips, to adjust the working temperature of the equipment to be temperature-controlled. Of course, the equipment to be temperature-controlled can also be other equipment.

[0033] According to the structure described above, in the temperature control system provided in the present application, a circulating refrigeration structure can be used to heat or cool the liquid in the circulating liquid supply component 2, such as water, so that the circulating liquid supply component 2 provides temperature-control liquid to the temperature-controlled equipment to adjust the working temperature of the temperature-controlled equipment to achieve precise temperature control.

[0034] Among them, the first temperature sensor 104 and the second temperature sensor 105 are located in front and back of the same copper tube, and the detected temperature values ​​are basically the same. After the equipment is running, the temperature value detected by the first temperature sensor 104 is T2, the temperature value detected by the second temperature sensor 105 is T3, and the pressure value detected by the first pressure sensor 106 is P1. The saturated evaporation temperature of the refrigerant corresponding to the pressure value P1 is T4. When the equipment is running stably, the temperature difference ΔT2=T3-T2 and the suction superheat ΔT3=T2-T4 of the two temperature sensors are calculated. If ΔT2 and ΔT3 remain unchanged, it is determined that the use of the first temperature sensor 104 and the second temperature sensor 105, that is, the spare temperature sensors, are normal, and the system adjustment does not need to take action;

[0035] If ΔT2 changes greatly instantly, while ΔT3 remains unchanged, it is determined that the spare second temperature sensor 105, i.e., the spare sensor, is abnormal. When the customer shuts down, the second temperature sensor 105, i.e., the spare sensor, is replaced;

[0036] If ΔT2 and ΔT3 change greatly at the same time and become consistent after a delay of several seconds, it is determined that the first temperature sensor 104 is abnormal. At this time, the first temperature sensor 104 is switched to the second temperature sensor 105, which is the backup sensor, and the first temperature sensor 104 is replaced when the customer shuts down.

[0037] It can be seen that the use of dual temperature sensors for detection in this system can effectively prevent refrigeration system failures caused by temperature sensor device failures due to vibration of the compressor 101, thereby preventing sudden shutdowns and ensuring the normal operation of customer equipment, which helps to improve production efficiency and customer satisfaction.

[0038] In this embodiment, preferably, Figure 1 As shown, the heating and cooling assembly 1 further includes a first electronic expansion valve 107 , and the first electronic expansion valve 107 is disposed on a pipeline between the condenser 102 and the first heat exchange channel of the evaporator 103 .

[0039] According to the structure described above, it can be known that the difference between the saturated vapor temperature value T4 of the refrigerant corresponding to the temperature value T2 detected by the first temperature sensor 104 and the pressure value detected by the first pressure sensor 106 is the suction superheat. The suction superheat needs to be stabilized within a certain range, and then it is necessary to adjust the opening of the first electronic expansion valve 107 to ensure that the superheat is within a suitable stable range.

[0040] When ΔT2 and ΔT3 change greatly at the same time and become consistent after a delay of several seconds, it is determined that the device of the first temperature sensor 104 is abnormal. At this time, the first temperature sensor 104 is switched to the second temperature sensor 105, that is, the second temperature sensor 105 is used to detect the temperature and calculate the corresponding intake superheat, and then the first electronic expansion valve 107 is adjusted to operate so that the superheat is within a suitable stable range.

[0041] In this embodiment, preferably, Figure 1 As shown, the heating and cooling assembly 1 further includes a drying filter 108 , and the drying filter 108 is disposed on the pipeline between the condenser 102 and the first electronic expansion valve 107 .

[0042] According to the structure described above, it can be known that the drying filter 108 mainly plays the role of filtering out impurities in the refrigerant, improving the refrigeration effect, and avoiding clogging of other components in the system.

[0043] In this embodiment, preferably, Figure 1 As shown, the heating and cooling assembly 1 further includes a liquid sight glass 109 , and the liquid sight glass 109 is disposed on the pipeline between the drying filter 108 and the first electronic expansion valve 107 .

[0044] According to the structure described above, the sight glass 109 is often made of glass and steel by high temperature sintering process. The sight glass 109 has good strength and high glass transparency, so it is suitable for use in refrigeration structures, which makes it easy to observe whether the amount of refrigerant decreases and whether it needs to be replenished.

[0045] In this embodiment, preferably, Figure 1 As shown, the temperature adjustment system further includes a controller, and the controller is communicatively connected with the first temperature sensor 104 , the second temperature sensor 105 , the first pressure sensor 106 , and the first electronic expansion valve 107 , respectively.

[0046] According to the structure described above, the values ​​detected by the first temperature sensor 104, the second temperature sensor 105 and the first pressure sensor 106 are all transmitted to the controller, and the controller can process, calculate and judge the above data, and finally control the first electronic expansion valve 107 to operate to ensure that the superheat in the system is within a suitable stable range.

[0047] Furthermore, preferably, the controller may be an existing Yokogawa F3 series controller.

[0048] Of course, instead of using a controller for intelligent control, the above process can be judged and operated manually, which is also achievable.

[0051] According to the structure described above, when heating is needed, the second electronic expansion valve 111 is opened, and the high-temperature and high-pressure gas discharged from the compressor 101 directly enters the first heat exchange channel of the evaporator 103 through the hot gas branch pipe 110, and then exchanges heat with the water in the second heat exchange channel to achieve heating operation.

[0052] When cooling is needed, the second electronic expansion valve 111 is closed, and the high-temperature and high-pressure gas discharged from the compressor 101 enters the condenser 102 for condensation, and then forms a high-pressure and low-temperature liquid, which then passes through the electromagnetic expansion valve to form a low-temperature and low-pressure liquid. This low-temperature and low-pressure liquid enters the first heat exchange channel of the evaporator 103, and then exchanges heat with the water in the second heat exchange channel to achieve cooling operation.

[0053] In this embodiment, preferably, Figure 1 As shown, the circulating liquid supply assembly 2 includes a water tank 203, a water pump 204 and a heater 205;
