All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application shall fall within the scope of the protection of the embodiments in the present application.
The following further describes specific implementations of embodiments of the present application with reference to the drawings of the embodiments of the present application.
An embodiment of the present application provides a cooling cycle control system, which is used for a cooling cycle system, where the cooling cycle system includes at least one heat exchange unit and a cooling tower, and the cooling tower is provided with a first fan and a second fan, where, as shown in fig. 1, fig. 1 is a schematic structural diagram of the cooling cycle control system provided in the embodiment of the present application, and the cooling cycle control system includes:
the system comprises at least one temperature early warning unit 101 used for detecting the temperature of the heat exchange unit or the outlet water of the cooling tower, and a fan monitoring unit 102 used for monitoring the working state of at least one first fan and at least one second fan arranged on the cooling tower; the temperature early warning unit is arranged on a water outlet pipeline of the at least one heat exchange unit 10 and/or the cooling tower 11, so that when the fan monitoring unit 102 monitors that the at least one first fan or the second fan fails and the temperature early warning unit 101 monitors that the water outlet temperature of the at least one heat exchange unit 10 is greater than a first temperature threshold value, the cutting machine control unit controls the cutting machine of the cooling circulation system;
or, when the fan monitoring unit 102 monitors that the at least one first fan or the second fan has a fault and the temperature of the outlet water of the cooling tower is greater than a second temperature threshold, the generator tripping control unit is enabled to perform generator tripping control on the cooling circulation system.
In a practical application scenario of the embodiment, the cooling tower is often used in a use environment of cooling of a data center room. Data center's cooling circulation system generally divide into refrigerating system and cooling system, refrigerating system is responsible for providing the cold source for the computer lab, and let the refrigerated water take away the heat of computer lab exchange, when the heat exchange unit, refrigerated water and cooling water exchange heat, make the refrigerated water temperature reduce, the cooling water carries the heat of refrigerated water release and sends to the cooling tower, the cooling water evaporation in the cooling tower is accelerated to at least one first fan and the second fan through the setting of cooling tower, with heat release to the nature in, consequently, at this in-process, at least one first fan and second fan on the cooling tower play very important effect.
In an actual application scenario of this embodiment, a refrigeration system (also called a refrigeration side) in a cooling circulation system of a data center machine room generally further includes an air conditioner 12, a refrigeration water pump 13, and the like, which are connected by a water pipe, and chilled water is provided in the water pipe; the cooling system (also referred to as cooling side) generally includes a cooling tower 11, a cooling water pump 14, and the like, which are also connected by water pipes in which cooling water is contained. Since at least one heat exchange unit provided in the refrigeration system is a place where the chilled water and the cooling water exchange heat, the heat exchange unit belongs to both the refrigeration side and the cooling side. The direction of the frozen water flow in the freezing side forms a closed loop, and concretely, if the frozen water flows out of the air conditioner, the frozen water flows to the frozen water pump, then flows to the heat exchange unit, exchanges heat with cooling water in the heat exchange unit, and finally flows to the air conditioner after heat exchange is finished, so that the closed loop flowing to the air conditioner is formed. The direction of the cooling water flow in the cooling side forms a closed loop, and specifically, if the cooling water firstly flows out from the water outlet of the cooling tower, then flows to the cooling water pump, then flows from the cooling water pump to the heat exchange unit, exchanges heat with the chilled water in the heat exchange unit, and then flows to the cooling tower, so that a flowing closed loop is formed.
In the application, because most of the cooling circulation systems mainly used in the industry are in a group control working state, and a plurality of fans are often arranged on a cooling tower, wherein a fault of any one fan can cause system shutdown, thereby generating a generator tripping control instruction and affecting the safety of a data center machine room, in the embodiment, in order to reduce the generation of the generator tripping instruction, the working state of the fan is monitored by arranging a fan monitoring unit, and a temperature early warning unit is arranged to monitor the temperature of a water outlet of the cooling tower or the temperature of a water outlet of a heat exchange unit, so that when a single fan fault occurs on a first fan or a second fan on the cooling tower, the generator tripping control unit can carry out generator tripping control according to whether the temperature of the water outlet of the cooling tower or the temperature of the water outlet of the heat exchange unit can meet the cooling requirement at the current moment, thereby avoiding the generator tripping control phenomenon caused by the single fan fault in the group control state, the frequency of cutting the machine is reduced, and the working stability of the cooling circulation system is effectively improved.
Optionally, in order to better improve the stability of the operation of the cooling system, a fan adjusting unit may be further disposed in the cooling circulation control system, and the fan adjusting unit is communicatively connected to the fan monitoring unit and configured to adjust the operating frequency of the second fan to a predetermined frequency when the fan monitoring unit monitors that the at least one first fan fails; or when the fan monitoring unit monitors that the second fan has a fault, the working frequency of the at least one first fan is adjusted to the preset frequency.
For example, in a specific application scenario of the embodiment, for example, the cooling tower 11 is provided with two fans, and the operating frequency of each fan under a general condition is 24HZ, when the fan monitoring unit detects that one of the fans fails and cannot normally operate, the operating frequency of the other fan that can normally operate can be increased by the fan adjusting unit, for example, to 48HZ, so as to increase the evaporation amount caused by the operation of a single fan, so that the cooling efficiency of the cooling circulation system is more stable, the generator tripping control instruction generated by the generator tripping control unit is reduced, and the stability of the operation of the cooling circulation system is better improved.
Optionally, in an embodiment of the present application, as shown in fig. 2, fig. 2 is a schematic structural diagram of another cooling cycle control system provided in the embodiment of the present application, and is applied to a cooling cycle system further including at least one refrigeration apparatus 15, in which at least one temperature early warning unit 101 is disposed on an outlet pipe of the refrigeration apparatus 15, so that when the fan monitoring unit monitors that the at least one first fan or the second fan fails, and the temperature early warning unit monitors that an outlet water temperature of the at least one refrigeration apparatus is greater than a third temperature threshold, the cutting machine control unit performs cutting machine control on the cooling cycle system.
In a specific application scenario of the present embodiment, as shown in fig. 2, there is also a cooling cycle, in which a refrigeration system is generally provided with at least one refrigeration device 15, such as a refrigeration unit, which is also one of the places where the refrigeration water and the cooling water exchange heat, and therefore, the refrigeration unit and the plate heat exchanger are both on the refrigeration side and the cooling side. Specifically, for example, chilled water flows out from a water outlet of the refrigeration unit, flows to the air conditioner, flows to the chilled water pump from the air conditioner, flows to the plate heat exchanger, exchanges heat with cooling water at the plate heat exchanger, and flows to the refrigeration unit for primary heat exchange after heat exchange is completed, so as to form a closed loop in the flow direction. The cooling water on the cooling side firstly flows out from a water outlet of the cooling tower, flows to the cooling water pump, then flows to the plate heat exchanger from the cooling water pump, exchanges heat with the chilled water at the plate heat exchanger, then flows to the refrigerating unit, exchanges heat with the chilled water once again in the refrigerating unit, and finally flows to the cooling tower after heat exchange is finished, so that a closed loop flowing to the cooling tower is formed. In order to further reduce the frequency of the generator tripping control instruction generated by the cooling circulation system with the structure, a temperature early warning unit can be arranged at the water outlet of the refrigeration equipment such as a refrigeration unit, when the temperature of the water outlet of the refrigeration equipment exceeds a third temperature threshold, the temperature early warning unit only carries out early warning, and the generator tripping control unit does not carry out generator tripping control immediately; and only when the single fan fault occurs on the cooling tower and the water outlet temperature of the refrigeration equipment is greater than a third temperature threshold value, the generator tripping control unit can send a generator tripping control instruction, so that the working stability of the cooling circulation system is further reduced.
In this embodiment, the temperature early warning unit includes that a water temperature sensor closes early warning device, such as bee calling organ etc. this application embodiment here does not limit the structure of temperature early warning unit.
Specifically, as shown in fig. 3, fig. 3 is a schematic structural diagram of another cooling cycle control system provided in an embodiment of the present application, and in a specific implementation manner of this embodiment, the cooling cycle system has three operation modes: in the natural cooling mode, that is, when heat exchange in the cooling cycle system is performed only in a heat exchange unit such as the plate heat exchanger 10, the refrigerating unit 15 is in a working state of being just started, and at this time, the temperature early warning unit 101 is disposed between the plate heat exchanger 10 and the air conditioner 12 to detect the outlet water temperature of the heat exchange unit in the current working state; a pre-cooling mixed mode, namely, when heat exchange in a cooling circulation system is performed twice in the plate heat exchanger 10 and the refrigerating unit 15, because the refrigerating efficiency of the refrigerating unit 15 is generally a constant value when the refrigerating unit 15 works normally, the temperature early warning unit 101 is only required to be arranged at a water outlet position on the freezing side of the plate heat exchanger 10 to monitor the water outlet temperature at the position; in this embodiment, the cooling cycle system further has a working mode, that is, a cooling machine mode, at this time, the plate heat exchanger 10 is in an isolated state, and only performs a heat exchange mode in the refrigerating unit 15, because the water outlet temperature of the refrigerating unit 15 during normal operation is a fixed value, the temperature early warning unit 101 can be arranged at the water outlet position of the cooling tower, and the water outlet temperature at the position can be monitored.
Optionally, in an implementation manner of this embodiment, the cooling cycle control system further includes: the delay control unit is in communication connection with the cutter control unit;
the delay control unit is used for delaying a first preset time for carrying out switching control on the cooling circulation system when the fan monitoring unit detects that the at least one first fan or the second fan has a fault and the temperature early warning unit monitors that the outlet water temperature of the at least one heat exchange unit is greater than a first temperature threshold;
or, when the fan monitoring unit detects that the at least one first fan or the second fan fails and the temperature early warning unit monitors that the outlet water temperature of the cooling tower is greater than a second temperature threshold value, the generator tripping control unit delays a second preset time to carry out generator tripping control on the cooling circulation system;
or when the fan monitoring unit monitors that the at least one first fan or the second fan breaks down and the temperature early warning unit monitors that the outlet water temperature of the at least one refrigeration device is higher than a third temperature threshold value, the switching control unit delays a third preset time to carry out switching control on the cooling circulation system.
In the embodiment of the application, the delay control module can play a role in delaying the time for the cutter control unit to send the cutter control instruction, so that the frequent cutter control of the system caused by the fact that the water temperature monitored by the detection points of the temperature early warning units in different working states fluctuates up and down at the preset temperature is avoided, the refrigeration effect is ensured, and the working stability of the cooling circulation system is further improved.
Of course, in this embodiment, the first preset time, the second preset time, and the third preset time may be set by a user according to own experience, or may be obtained in other manners, which is not limited in this embodiment of the present application.
In another implementation scenario of this embodiment, the first preset time, the second preset time, and the third preset time may also be equal to or longer than the first preset time, in this case, when a single-fan fault occurs in the cooling tower and in the corresponding operating mode, each temperature early warning unit detects that the temperature of the corresponding detection point exceeds the preset temperature threshold, and the time for sending the generator tripping control instruction by the generator tripping control unit in a delayed manner is the same, so that the user can set the time.
The present embodiment is exemplified herein as an example for easy understanding, for example, the first preset time, the second preset time and the third preset time may be set to 30s, that is: when the fan monitoring unit detects that at least one fan of the cooling tower breaks down, and the temperature of the water monitored by the temperature early warning unit is always higher than the preset temperature within the preset time, the delay control module delays for 30s to enable the generator tripping control unit to send a generator tripping control instruction, and marks the current cooling circulation system as unavailable, so that the generator tripping control unit generates the generator tripping control instruction.
Of course, the above is only an example convenient for understanding, and the first preset time, the second preset time and the third preset time are all set to be 30S, which may sufficiently meet the start-stop requirement of the cooling tower in some cases, but it should be understood that the present embodiment is not limited thereto, for example, the first preset time is set to be 20S, the second preset time is set to be 30S, the third preset time is set to be 40S, and the like, which should be considered to be within the protection scope of the embodiment of the present application, and the present embodiment is not described herein again.
In order to facilitate setting or adjusting the above parameters, such as at least one of the first temperature threshold, the second temperature threshold, the third temperature threshold, the first preset time period, the second preset time period, the third preset time period, and the like, the cooling cycle control system of the embodiment of the present application may further include a setting unit;
specifically, the setting unit is in communication connection with the record cutting control unit, and the record cutting control unit performs record cutting control through the parameter values set by the setting unit.
The embodiment of the application does not limit the specific structure of the setting unit, and the setting unit can be a fixed setting key which is directly used for setting. In an alternative embodiment, the setting unit comprises a human-machine display interface. That is to say, the user can visually set the first temperature threshold, the second temperature threshold, the third temperature threshold, the first preset time, the second preset time and the third preset time in the human-computer display interface, and the current set value, other system parameters and the like can be displayed on the human-computer display interface, so that the operation of the user and the checking and setting of the states of the cooling circulation system and the cooling circulation control system can be facilitated.
In one embodiment, the setting unit is a computer, and the computer includes a human-computer display interface, wherein the human-computer display interface is a host computer control interface corresponding to the refrigeration system. Of course, the upper computer control interface may not be a computer, such as a terminal device like a PAD, a touchable screen on a refrigeration device, and the like, and the application is not limited either.

The specific type is not limited in this application.
It should be noted that the temperature and humidity sensor is used for determining the outdoor wet bulb temperature. The outdoor wet bulb temperature is an important parameter of the cooling tower, generally changes along with the change of the outside weather, and the physical significance of the outdoor wet bulb temperature is that the outdoor wet bulb temperature can reflect the limit temperature to which water can be cooled in the cooling tower. That is to say, the preset water temperature of the cooling tower is associated with the preset water temperature of the cooling tower, and the value of the preset water temperature of the cooling tower is determined according to the outdoor wet bulb temperature determined by the outdoor temperature and humidity, for example, when the outdoor wet bulb temperature is lower, the working efficiency of a single fan of the cooling tower can meet the working requirement of cooling the data center machine room of the cooling circulation system, at this time, the setting unit can relatively prolong the first preset time, the second preset time and the second preset time, or adjust the temperature value range of the first temperature threshold, the second temperature threshold or the third temperature threshold, so that the frequency of generating the generator tripping control instruction by the generator tripping control unit is reduced, and the stability of the working state of the cooling circulation system is improved.
