The embodiment of the utility model provides a cooling system which can be arranged in a data center to refrigerate and dissipate heat of the data center, and of course, the cooling system can also be arranged in other spaces with higher heat generating efficiency to refrigerate and dissipate heat.
As shown in fig. 1, the cooling system includes a fan coil 1, a natural cooling device 2, and a mechanical refrigeration device 3, wherein the fan coil 1 can be disposed in a data center room, and the fan coil 1 has a liquid inlet pipe 11 and a liquid outlet pipe 12, so as to inject and discharge liquid into the fan coil 1 through the liquid inlet pipe 11 and the liquid outlet pipe 12.
The liquid inlet pipe 11 and the liquid outlet pipe 12 are respectively connected to the natural cooling device 2, so that the refrigerant in the fan coil 1 is input into the natural cooling device for heat dissipation, and can enter the fan coil 1 again after the heat dissipation is finished, so as to perform heat exchange in the data center machine room. The mechanical refrigeration equipment 3 can be arranged on the liquid inlet pipe 11, so that when the natural cooling device 2 cannot effectively cool the refrigerant, the mechanical refrigeration equipment can be used for further refrigerating the refrigerant in the liquid inlet pipe 11.
The coolant can be water or a mixed solution of water and glycol, the natural cooling device 2 can be a natural cooling tower, the coolant in the fan coil 1 is input into the natural cooling tower through the liquid outlet pipe 12 for sufficient cooling, and then the coolant enters the fan coil 1 through the liquid inlet pipe 11.
In one embodiment, as shown in fig. 1, the cooling system further includes a measuring chamber 4, the measuring chamber 4 has a water outlet and a water inlet, and a temperature detector 41 is fixedly installed at the water inlet of the measuring chamber 4. The liquid inlet pipe 11 comprises a first portion 111 and a second portion 112, one end of the first portion 111 is connected to the natural cooling device 2, the other end of the first portion is connected to the water inlet of the measuring cavity 4, one end of the second portion 112 is connected to the water outlet of the measuring cavity 4, and the other end of the second portion is connected to the fan coil 1. In this way, the refrigerant cooled in the natural cooling device 2 firstly passes through the measuring cavity 4 and then enters the fan coil 1.
The mechanical refrigeration equipment 3 is provided with a water inlet pipe 31 and a water outlet pipe 32, the water inlet pipe 31 is connected to the bottom of the measurement cavity 4, the water outlet pipe 32 is connected to the second part 112, the water inlet pipe 31 and the second part 112 are respectively provided with a control valve 5, and the control valve 5 on the second part 112 is arranged between the connection point of the water outlet pipe 32 and the second part 112 and the measurement cavity 4.
In this way, when the refrigerant flows into the measurement cavity 4, the temperature detector 41 can detect the temperature of the refrigerant entering the measurement cavity 4, so that whether the refrigerant needs to be input into the mechanical refrigeration equipment for refrigeration can be determined according to the temperature of the refrigerant. For example, when the temperature of the refrigerant is too high, the control valve 5 on the second portion 112 may be closed, the refrigerant on the water inlet pipe 31 may be opened, and the mechanical refrigeration apparatus may be operated, so that the refrigerant in the liquid inlet pipe 11 may enter the mechanical refrigeration apparatus for further refrigeration, and then may be discharged through the water outlet pipe 32.
Wherein, be provided with second water pump 8 on the second portion 112 of feed liquor pipe 11, and this second water pump 8 sets up on fan coil 1 and the second portion 112 of the position between outlet pipe 32 and the second portion 112 tie point to constantly draw the refrigerant through second water pump 8 and enter into fan coil 1 on.
In one embodiment, the cooling system further includes a controller, the control valves 5 disposed on the second portion 112 and the water inlet pipe 31 are electromagnetic valves, and the electromagnetic valves on the water inlet pipe 31 and the second portion 112 are electrically connected to the controller respectively to control the opening and closing of the electromagnetic valves.
In this way, when the water inlet pipe 31 and the control valve 5 on the second part 112 need to be controlled to be opened or closed, the opening or closing can be realized only by the controller, and the use is convenient.
Further, the temperature detector 41 is a temperature sensor electrically connected to the controller, and the temperature detector 41 is configured to detect temperature information of the refrigerant entering the measurement chamber 4 and transmit the temperature information to the controller. And the mechanical refrigeration equipment is also electrically connected with the controller, and the controller can control the operation or the closing of the mechanical refrigeration equipment.
The controller is internally provided with a preset temperature threshold, when the temperature information transmitted to the controller by the temperature sensor is greater than the preset temperature threshold, the controller controls the electromagnetic valve on the water inlet pipe 31 to be opened, controls the electromagnetic valve on the second part 112 to be closed, and controls the mechanical refrigeration equipment to operate, so that the refrigerant enters the mechanical refrigeration equipment through the water inlet pipe 31 for refrigeration. That is, when the temperature of the refrigerant entering the measurement cavity 4 is too high, the temperature sensor transmits the temperature information to the controller, and compares the temperature information with the preset temperature information, so as to determine whether the refrigerant is input into the mechanical refrigeration equipment for refrigeration. Correspondingly, when the temperature sensor detects that the temperature information of the refrigerant is lower than the preset threshold value, the electromagnetic valve on the water inlet pipe 31 is closed, the electromagnetic valve on the second portion 112 is opened, and the mechanical refrigeration equipment stops running, so that the refrigerant directly enters the fan coil 1 through the second portion 112.
In another embodiment, the cooling system may further include a timer (not shown) electrically connected to the controller, and the controller may control the timer to start timing when the temperature information detected by the temperature sensor is greater than the preset temperature threshold, so as to calculate a time when the temperature information transmitted by the temperature sensor is greater than the preset temperature threshold, and transmit the time information to the controller.
The controller is internally provided with preset time information, and when the time information is greater than a preset time threshold and the temperature information is continuously greater than a preset temperature threshold, the controller controls the electromagnetic valve on the water inlet pipe 31 to be opened, controls the electromagnetic valve on the second part 112 to be closed, and controls the mechanical refrigeration equipment to operate.
That is to say, when the temperature sensor detects that the temperature information of the refrigerant is greater than the preset temperature threshold, and after the controller receives the information, the controller may control the timer to operate to time, so as to start to detect the time that the temperature of the refrigerant is continuously greater than the preset temperature threshold, and when the time information timed by the timer is greater than the preset time information and the temperature information is continuously greater than the preset temperature threshold, the controller may control the electromagnetic valve on the water inlet pipe 31 to open, so that the electromagnetic valve on the second portion 112 is closed, and the mechanical refrigeration device is controlled to operate. For example, the preset time information is 30 seconds, and the operation of the mechanical refrigeration equipment is controlled only if the temperature information detected by the temperature sensor is always greater than the preset temperature threshold value within the timed 30 seconds. Correspondingly, if the temperature information detected by the temperature sensor is lower than the preset temperature threshold value when the timed time information does not exceed the preset time threshold value, the operation of the mechanical refrigeration equipment does not need to be controlled, so that the refrigerant continuously flows into the fan coil 1 through the second portion 112. By the method, the over-high temperature of the refrigerant can be relatively accurately determined, and the refrigerant needs mechanical refrigeration equipment to refrigerate, so that the waste of resources caused by randomly starting the mechanical refrigeration equipment is further avoided.
In an embodiment, as shown in fig. 1, a first water pump 7 is disposed on a water inlet pipe 31 of the mechanical refrigeration device, the first water pump 7 is electrically connected to the controller, and through the arrangement of the first water pump 7, when the temperature of the refrigerant is too high and needs to be input into the mechanical refrigeration device for refrigeration, the controller immediately controls the first water pump 7 to operate, so as to quickly pump the refrigerant into the mechanical refrigeration device.
In an embodiment, the water outlet pipe 32 of the mechanical refrigeration apparatus 3 is provided with the check valve 33, by the arrangement of the check valve 33, it is avoided that the refrigerant in the second portion 112 enters the mechanical refrigeration apparatus through the water outlet pipe 32 under the condition that the mechanical refrigeration apparatus is not turned on, and meanwhile, the check valve 33 does not influence the refrigerant in the mechanical refrigeration apparatus to enter the second portion 112.

When the controller controls the mechanical refrigeration equipment to operate, the refrigerant in the natural cooling device 2 cannot be sufficiently cooled to a specified temperature, and at the moment, the controller can control the fan to operate, and the air flow rate of the natural cooling device 2 is increased so as to accelerate the cooling speed of the refrigerant. Meanwhile, the controller can also control the rotating speed of the refrigerating fan 6, so that whether the wind power of the refrigerating fan 6 is increased or not is determined according to needs, and the refrigerant is fully cooled.
According to the utility model, the measuring cavity 4 is arranged on the liquid inlet pipe 11 of the fan coil 1, the temperature detector 41 is arranged at the water inlet of the measuring cavity 4, and the water inlet pipe 31 and the water outlet pipe 32 of the mechanical refrigeration equipment are respectively connected to the measuring cavity 4 and the second part 112, so that the refrigerant can enter the mechanical refrigeration equipment from the measuring cavity 4 for refrigeration only when the temperature of the refrigerant detected by the temperature detector 41 is higher than a certain temperature, and then the refrigerant is conveyed into the fan coil 1. By the mode, the mechanical refrigeration equipment can be utilized to refrigerate the refrigerant after the temperature of the refrigerant is too high, so that the problem that the temperature of the refrigerant is too high and the refrigerant cannot be well refrigerated to a data center machine room is avoided.
