Problems solved by technology

[0003] The cooling circulation system generally includes a natural cooling tower and a refrigerator. The existing control scheme is a one-size-fits-all method, which simply judges according to the ambient temperature. When the ambient temperature is low, the natural cooling tower is directly used to dissipate the waste heat on the process side. However, when the ambient temperature is high, the waste heat on the process side must be treated with a refrigerator. This control method is too rough and wastes a lot of energy.

Embodiment 1

[0057] For the process side, once the process device 4 is determined, the inlet cooling temperature T of the refrigerant inlet 41 2 , the cooling temperature T of the refrigerant outlet 42 3 are determined, in an exemplary scheme, T 2 can be 12°C, T 3 It can be 18°C. If the ambient temperature is low, only the natural cooling solution can meet the cooling requirements, but if the ambient temperature is high, the refrigerator 3 needs to be used for high-efficiency cooling.

[0058] In the traditional solution, once the natural cooling cannot meet the requirements, the refrigerator 3 will be fully used for cooling. However, the ambient temperature is not constant. It is very large. It is very likely that the temperature in the morning and evening is only a few degrees, but the temperature at noon can reach 20 to 30 degrees. If the cooling source (natural cooling source, refrigerator 3) is switched across the board, it will inevitably lead to natural cooling. The utilization o...

Embodiment 2

[0086] This embodiment also provides a cooling cycle system, including a refrigerant tank 1, a closed cooling device 2 and a refrigerator 3, and the cooling cycle system communicates with the refrigerant inlet 41 and the refrigerant outlet 42 of the process device 4; it also includes a second A temperature sensor, a second temperature sensor and a third temperature sensor, the first temperature sensor is used to monitor the refrigerant temperature T of the refrigerant tank 1 1, the second temperature sensor is located at the refrigerant inlet 41 for monitoring the inlet cooling temperature T in the refrigerant outlet 42 2 , the third temperature sensor is located at the refrigerant outlet 42 for monitoring the cooling temperature T in the refrigerant outlet 42 3 ; Also includes a controller (not shown in the figure), the controller is connected with the first temperature sensor, the second temperature sensor signal, the controller is suitable for cooling temperature T 2 1 3 U...

Abstract

The invention discloses a cooling circulation system and a control method thereof. The cooling circulation system comprises a refrigerant tank, a closed heat dissipation device and a refrigerating machine, the cooling circulation system is communicated with a refrigerant inlet and a refrigerant outlet of the process device, the control method comprises the following steps of S1, acquiring the temperature of the refrigerant in the refrigerant box, the air inlet temperature of the refrigerant inlet and the air outlet temperature at the refrigerant outlet; S2, comparing the refrigerant temperature, the air inlet temperature and the air outlet temperature, and if the air inlet temperature is smaller than the cold temperature of the refrigerant and the cold temperature is smaller than the coldoutlet temperature, executing the step S3; S3, introducing a refrigerant discharged from the refrigerant outlet into a closed heat dissipation device; S4, controlling the refrigerant discharged from the closed heat dissipation device to pass into the refrigerant box; S5, introducing the refrigerant discharged from the refrigerant box into an evaporator of the refrigerator; and S6, controlling therefrigerant discharged by the evaporator to pass into a refrigerant inlet. According to the system and the control method, the system energy consumption can be reduced, the attenuation of the performance of the refrigerating machine can be overcome to a great extent, and the refrigerating efficiency of the refrigerating machine is ensured.

Description

technical field [0001] The invention relates to the technical field of cooling cycles, in particular to a cooling cycle system and a control method thereof. Background technique [0002] In the industrial and information industry process, in order to maintain the continuous progress of the process, it is necessary to adopt a cooling cycle system to undertake the task of taking out and disposing of the "waste heat" generated in the manufacturing equipment (process side) of the industrial and information industry . [0003] The cooling circulation system generally includes a natural cooling tower and a refrigerator. The existing control scheme is a one-size-fits-all method, which simply judges according to the ambient temperature. When the ambient temperature is low, the natural cooling tower is directly used to sell the waste heat on the process side. However, when the ambient temperature is high, the waste heat on the process side must be treated with a refrigerator. This c...
