For example, after the power consumption of the equipment is instantly reduced, the liquid inlet temperature of the equipment is suddenly reduced, so that the supercooling degree of a two-phase working medium entering the equipment is high, and the heat exchange capability of the equipment is poor. In addition, even under the condition that the power consumption fluctuation is not large, due to the safety requirement of a pump in pump-driven two-phase equipment, the supercooling degree of more than 5 ℃ is generally required to be ensured in front of the pump, and the problem that the heat exchange capacity of the equipment is reduced due to the high supercooling degree of the two-phase working medium entering the equipment also exists.

However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solutions claimed in the claims of the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.
A first embodiment of the present invention is directed to a temperature control system 100, as shown in FIG. 1. The core of this embodiment lies in, temperature control system 100 includes working medium liquid reserve tank 1, drain pipe 4, return liquid pipeline 8, liquid outlet 6 and return liquid mouth 7, the export of working medium liquid reserve tank 1 is connected to the one end of drain pipe 4, liquid outlet 6 is connected to the other end, return liquid pipeline 8 one end is connected return liquid mouth 7, the entry of working medium liquid reserve tank 1 is connected to the other end, working medium direction of delivery along drain pipe 4 has set gradually first pressure and temperature sensor 2, circulating pump 3, and regenerator 5, working medium direction of delivery along return liquid pipeline 8 has set gradually regenerator 5, and cooling device 10, drain pipe 4 and return liquid pipeline 8 exchange heat and each other intercommunication in regenerator 5 department, liquid outlet 6 and return liquid mouth 7 are used for connecting the entry and the export of waiting to control the temperature equipment respectively.
The temperature control system of the embodiment can detect the pressure and the temperature of the working medium before entering the circulating pump by arranging the first pressure and temperature sensor in front of the circulating pump, and calculate the supercooling degree according to the pressure and the temperature, so that the heat exchange of the cooling device on the working medium can be controlled according to the supercooling degree, and the supercooling degree of the working medium before entering the circulating pump is adjusted to meet the safety requirement of the circulating pump; in addition, the heat regenerator is arranged behind the circulating pump, so that the working medium flowing into the equipment to be controlled in front of the equipment to be controlled and the working medium flowing out of the equipment to be controlled are subjected to heat exchange at the heat regenerator, the supercooling degree of the working medium is reduced, the working medium is ensured to enter the equipment to be controlled in a saturated state, and the heat exchange capacity of the equipment is improved.
The following is a detailed description of the implementation details of the temperature control system of the present embodiment, and the following is provided only for the convenience of understanding and is not necessary for implementing the present embodiment.
As shown in fig. 1, the liquid outlet 6 and the liquid return port 7 of the temperature control system 100 of this embodiment are used for connecting with an inlet and an outlet of a device to be controlled, so that the temperature control system 100 and the device to be controlled form a working medium circulation loop, and a conveying direction of the working medium is shown by an arrow in fig. 1. A gas-liquid two-phase working medium flowing in a circulation loop is stored in the working medium liquid storage tank 1, and the working medium flows out of the working medium liquid storage tank 1, is pressurized by a circulating pump 3 and then is sent into a liquid outlet pipeline 4, and then flows through a heat regenerator 5 and a liquid outlet 6 to enter the temperature control equipment to be controlled; after heat exchange is carried out in the temperature control equipment, the working medium enters the liquid return pipeline 8 through the liquid return port 7, then flows through the heat regenerator 5 and the cooling device 10, and finally returns to the working medium liquid storage tank 1, so that the circulation of the working medium is completed.
The working medium liquid storage tank 1 is used for compensating the two-phase working medium and controlling the saturation temperature of the two-phase working medium. The interior of the working medium liquid storage tank 1 is always in a gas-liquid two-phase saturated state, so that the temperature and the pressure of the working medium in the working medium liquid storage tank 1 correspond to each other one by one. By controlling the temperature of the working medium in the working medium liquid storage tank 1, the pressure of the working medium in the working medium liquid storage tank 1 can be controlled, and further the pressure of each position of the temperature control system 100.
The first pressure and temperature sensor 2 is arranged at the inlet position of the circulation pump 3 or at a position close to the inlet of the circulation pump 3, and is used for detecting a first pressure and a first temperature of the working medium before flowing into the circulation pump 3. According to the detected first pressure and first temperature, the corresponding supercooling degree can be calculated. In general, the supercooling degree before entering the circulating pump 3 should not be less than 5 ℃ in order to ensure the safe operation of the circulating pump. Therefore, if the supercooling degree of the working medium before entering the circulating pump 3 does not meet the safety requirement, the working state of the cooling device 10 in the liquid return pipeline 8 can be controlled, the heat exchange efficiency of the working medium passing through the cooling device 10 is improved, and the temperature of the working medium is further reduced. Therefore, the working medium entering the circulating pump 3 can be ensured to have proper supercooling degree without influencing the safe operation of the circulating pump. Further, the above calculations and control may be performed by a controller, which is in communication with the first pressure and temperature sensor 2 and the cooling device 10. The controller may be a processor or a hardware circuit. The controller can monitor and calculate the supercooling degree of the working medium in real time, and automatically control the heat exchange efficiency of the cooling device to the working medium according to the supercooling degree of the current working medium so as to automatically control the supercooling degree of the working medium.
The regenerator 5 is arranged behind the circulating pump 3, and the liquid outlet pipe 4 and the liquid return pipe 8 both pass through the regenerator 5. Working medium flowing into the liquid outlet pipe 4 from the circulating pump 3 exchanges heat with working medium flowing into the liquid return pipe 8 from the liquid return port 7 at the heat regenerator 5, so that on one hand, the temperature of the working medium flowing to the liquid outlet 6 in the liquid outlet pipe 4 can be increased to reduce the supercooling degree of the working medium entering the equipment to be controlled, and on the other hand, the temperature of the working medium flowing to the cooling device 10 in the liquid return pipe 8 can be reduced to reduce the heat load of the cooling device 10.
In the present embodiment, the cooling device 10 exchanges heat with the working medium in the liquid return line 8 so as to circulate the cooling liquid. However, it should be understood that in other embodiments, the cooling device 10 may also operate in other cooling modes (e.g., air cooling modes). In the present embodiment, please continue to refer to fig. 1, the cooling device 10 includes a cooling liquid storage tank 11, a condenser 13 and a cooling pipeline. The cooling line connects the outlet of the coolant reservoir 11 to the inlet of the condenser 13, and connects the inlet of the coolant reservoir 11 to the outlet of the condenser 13. The return line 8 and the cooling line exchange heat at the condenser 13 and are not in communication with each other. The cooling liquid storage tank 11 stores cooling liquid, the cooling liquid flowing out of the cooling liquid storage tank 11 enters the condenser 13 through the cooling pipeline, exchanges heat with the working medium in the liquid return pipeline 8, absorbs heat to raise the temperature, and then flows back to the cooling liquid storage tank 11 through the cooling pipeline to release heat, so that a cooling liquid circulation loop is formed. Therefore, the heat exchange efficiency of the condenser 13 to the working medium in the liquid return pipeline 8 can be controlled by controlling the flow and/or the flow velocity of the cooling liquid in the cooling pipeline, so that the supercooling degree of the working medium entering the circulating pump 3 can be accurately controlled.
Specifically, the cooling line includes a three-way valve 12 connected to an outlet of the coolant reservoir 11, and a first branch 14 and a second branch 15 provided between the three-way valve 12 and an inlet of the coolant reservoir 11. The inlet of the three-way valve 12 is connected with the outlet of the cooling liquid storage tank 11, and two outlets of the three-way valve 12 are respectively connected with the first branch 14 and the second branch 15 so as to divide the cooling liquid flowing out from the cooling liquid storage tank 11. The condenser 13 can be arranged on the first branch 14 or on the second branch 15. Therefore, the heat exchange efficiency of the condenser 13 to the working medium in the liquid return pipeline 8 can be controlled by controlling the opening degree of the three-way valve 12, and the supercooling degree of the working medium entering the circulating pump 3 is controlled.
Taking the case that the condenser 13 is disposed on the first branch 14 (as shown in fig. 1) as an example, when the supercooling degree of the working medium entering the circulation pump 3 needs to be increased, the heat exchange efficiency of the condenser 13 to the working medium in the liquid return pipeline 8 needs to be improved, and at this time, the opening degree of the three-way valve 12 to the first branch 14 may be increased and/or the opening degree of the three-way valve 12 to the second branch 15 may be decreased, so as to increase the flow rate and/or the flow velocity of the cooling liquid in the first branch 14, so as to improve the heat exchange efficiency. Conversely, the opening degree of the three-way valve 12 to the first branch 14 may be decreased and/or the opening degree of the second branch 15 may be increased, so as to decrease the flow rate and/or the flow velocity of the cooling liquid in the first branch 14, thereby decreasing the heat exchange efficiency. Further, the control of the three-way valve 12 can be automatically achieved by a controller, and as shown in fig. 2, the temperature control system 100 of the present embodiment further includes a controller 16 communicatively connected to the first pressure and temperature sensor 2 and the three-way valve 12. The controller 16 may be a processor or a hardware circuit. The controller 16 can monitor and calculate the supercooling degree of the working medium in real time, and automatically control the three-way valve 12 according to the supercooling degree of the current working medium to control the heat exchange efficiency of the condenser 13 to the working medium, thereby realizing the automatic control of the supercooling degree of the working medium.
A second embodiment of the present invention is directed to another temperature control system 100', as shown in fig. 3. The temperature control system 100 ' provided in the second embodiment is substantially the same as the temperature control system 100 provided in the first embodiment, except that the temperature control system 100 ' further includes a preheater 9 disposed on the liquid outlet pipe 4 and a second pressure and temperature sensor 2 '. The preheater 9 and the second pressure and temperature sensor 2' are respectively arranged between the regenerator 5 and the liquid outlet 6 in the working medium conveying direction of the liquid outlet pipe 4.
When the power consumption of the equipment to be controlled is changed violently, the heat regenerator 5 can not ensure that the two-phase working medium is heated to the saturation state completely, so that the supercooling degree of the working medium entering the equipment to be controlled still exists. Thus, the provision of the preheater 9 and the second pressure and temperature sensor 2' may avoid such problems. The second pressure and temperature sensor 2' is arranged at a position close to the liquid outlet 6 and is used for detecting the second pressure and the second temperature of the working medium before flowing into the temperature control device to be controlled. And calculating the corresponding supercooling degree according to the detected second pressure and second temperature. If the supercooling degree still exists before the working medium enters the temperature-controlled equipment, namely the calculated supercooling degree is not zero, the preheater 9 can be controlled to be opened or the heating power of the preheater is increased, and the temperature of the working medium is further increased. Therefore, the supercooling degree of the working medium can be eliminated, and the working medium is ensured to enter the temperature control equipment to be controlled in a saturated state. Further, the above calculations and control may be automated by a controller, as shown in FIG. 4, where the controller 16 is communicatively connected to the second pressure and temperature sensors 2' and the preheater 9. The controller 16 may be a processor or a hardware circuit. By arranging the controller 16, in addition to the effects described in the first embodiment, the supercooling degree of the working medium can be automatically controlled according to the heating power of the automatic preheater 9 for the supercooling degree of the current working medium.
It should be noted that the design schemes of the structures, materials, and the like of the components provided in the first embodiment of the present invention can also be applied to the temperature control system 100' provided in the second embodiment, and are not described herein again.

Evaporator 200 includes an inlet connected to outlet 6 of temperature control system 100(100 ') and an outlet connected to return 7 of temperature control system 100 (100').
The fourth embodiment of the present invention also relates to a temperature control method 400, as shown in fig. 6. The temperature control method 400 in this embodiment can be applied to the temperature control system 100 according to the first embodiment or the temperature control system 100' according to the second embodiment. The temperature control method 400 in this embodiment includes the following steps.
401: a first temperature and a first pressure of the working medium before entering the circulation pump are detected. In this step, a first temperature T of the working fluid before entering the circulation pump 3 may be measured by means of a first pressure and temperature sensor 2 arranged at a position close to the inlet of the circulation pump 3 (or at the inlet of the circulation pump 3)1And a first pressure P1。

In this step, the first degree of subcooling Δ T may be determined by a controller 16 communicatively coupled to the chiller 101The degree of cooling of the working fluid flowing through the cooling device 10 by the cooling device 10 is controlled. In some of the embodiments described above, the controller 16 may be based on the first degree of subcooling Δ T1The three-way valve 12 is controlled to increase the opening degree of the first branch 14 and/or to decrease the opening degree of the second branch 15, or to decrease the opening degree of the first branch 14 and/or to increase the opening degree of the second branch 15.
The fifth embodiment of the present invention is also directed to another temperature control method 500, as shown in fig. 7. Steps 501-503 of the temperature control method 500 provided in the fifth embodiment are substantially the same as steps 401-403 of the temperature control method 400 provided in the fourth embodiment, and are not repeated herein. The difference is that the fifth embodiment provides a temperature control method 500 further comprising the following steps.
504: and detecting a second temperature and a second pressure of the working medium after flowing out of the heat regenerator.

It should be noted that the saturation temperature mentioned in the present application refers to the temperature that the gas phase and the liquid phase of the working fluid have in a dynamic equilibrium state (i.e. saturation state). When the working medium is in a saturated state, the temperature and the pressure of the working medium are not independent but are in one-to-one correspondence, and the correspondence is related to the physical property of the working medium. Therefore, in the case of a given pressure value, a saturation temperature value corresponding to the working medium under the pressure can be obtained, for example, by looking up a table (for example, physical data of different materials are described in a chemical and chemical physical data handbook published by a chemical industry publisher).
It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples for carrying out the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in practice.
