[0170] Based on the above cooling system, the embodiment of the present invention further provides a method for controlling the cooling system; for details, please refer to Fig. 9 , Fig. 9 A flow chart showing the steps of a method for controlling a cooling system according to an embodiment of the present invention is shown.

[0171] like Fig. 9 As shown, the method may include:

[0172] Step 901: Obtain the pressure and temperature of the circulating cooling medium.

[0173] In practical applications, the control device may first obtain the pressure and temperature of the cooling medium circulating in the cooling system; the temperature and pressure may be obtained by a sensor disposed in the most unfavorable end loop of the cooling system, and the embodiment of the present invention does not limit this.

[0174] Step 902: Control the first bypass pipeline, the second bypass pipeline, the circulation device and / or the cooling device in the cooling system according to the pressure and temperature of the circulating cooling medium.

[0175] After obtaining the pressure and temperature of the circulating cooling medium, the control device can control the first bypass pipe, the second bypass pipe, the circulation device and / or the cooling device in the cooling system to adjust the pressure and / or temperature of the cooling medium circulating in the cooling system.

[0176] Exemplarily, each cooling device and the corresponding circulation device together form a group of circulation pump units N (N=1, 2, 3), and the circulation pump units and valves are controlled by the control device.

[0177] 1) The frequency conversion of the circulation device is controlled by the terminal differential pressure sensor to maintain the set value of the terminal differential pressure of 0.15MPa. A terminal differential pressure sensor is set for each group of the most unfavorable terminal loop. Each group of circulating pump units N controls the frequency conversion of the water pump and the opening of the differential pressure bypass valve 2 according to the most unfavorable terminal loop pressure difference to ensure that the supply and return water pressure difference is not greater than 0.15MPa.

[0178] 2) Each circulating pump unit N controls the cooling medium supply temperature = 35°C through the cooling device frequency conversion and the opening of the electric valve, and is controlled by the cooling device spray pump start and stop and the cooling device fan frequency conversion. When the cooling device spray pump stops running and the cooling device fan is reduced to the minimum frequency of 30Hz, and is lower than the set value, the cooling device fan is first turned off to control this temperature. When the cooling device fans are all stopped but still lower than the set value, the bypass valve 1 is adjusted to control this temperature.

[0179] 3) Cooling device and circulation device are equipped with start-stop interlock

[0180] Start-up sequence: The control device sends the start-up command in sequence: select the circulation pump unit to be started, start a circulation device, and start the corresponding cooling device.

[0181] Shutdown sequence: The control device sends the shutdown command in sequence: select the circulation pump unit to be shut down, first shut down the cooling device, and then shut down the corresponding circulation device.

[0182] In winter (-5℃ and below, temperature is adjustable), hot standby mode is used:

[0183] After the circulating pump unit is successfully running, the control device calculates the terminal load based on the detected supply and return water temperature and flow rate of the circulating cooling medium (the parameter detection method is to collect a set of values ​​every 30 seconds, continuously sample for 5 minutes and then take the average value). If the flow meter fails, the control device will freeze its value and issue an emergency critical alarm at the operator's workstation. When the detected terminal load exceeds 90% of the rated cooling capacity of the running cooling device for 20 minutes, another set of circulating pump units should be turned on according to the running time and start-up strategy; when the detected terminal load is lower than 50% of the rated cooling capacity of the running cooling device for 20 minutes, a set of circulating pump units should be turned off according to the running time and stop strategy. When the actual operating conditions are significantly different from the design conditions and are maintained for a long time, so that only one set of circulating pump units is operated for a long time, only one set of circulating pump units can be considered to participate in hot backup.

[0184] The required value of the terminal differential pressure sensor is met by the frequency conversion of the circulation device. When the actual differential pressure at the terminal is less than the set value, the frequency of the chilled water pump is increased through PID (Proportional-Integral-Derivative) adjustment; when the actual differential pressure at the terminal is greater than the set value, the frequency of the chilled water pump is reduced through PID adjustment; at the same time, the operating frequency of the chilled water pump shall not be less than the minimum set value of the pump operation; the inverter itself should set the minimum operating frequency. If the differential pressure still cannot meet the requirements at the lowest frequency, the opening of the differential pressure bypass valve 2 is adjusted to ensure that the supply and return water pressure difference is not greater than 0.10MPa.

[0185] The conditions for automatic start-up of the electric heating device are: when the cooling device is in standby mode, the temperature of the cooling medium in the cooling device is lower than 2 degrees and the outdoor temperature is lower than 0 degrees, the electric heating device is started; when the temperature of the cooling medium in the cooling device is higher than 5 degrees, the electric heating device is turned off; when the cooling device is in operating mode, the electric heating device of the corresponding unit is always in the off state.

[0186] The cooling device and electric heating device will be controlled according to the temperature of the most unfavorable point detected by the electric heating to ensure that there will be no local freezing. The control mode is the same as that of electric heating. The electric heating will start when the temperature of the most unfavorable point detected is lower than 2 degrees and the outdoor temperature is lower than 0 degrees, and will stop at 5 degrees. The installation position of the electric heating temperature sensor will be determined according to the specific site environment.

[0187] In the embodiment of the present invention, the pressure and temperature of the circulating cooling medium are obtained; and the first bypass pipeline, the second bypass pipeline, the circulation device and / or the cooling device in the cooling system are controlled according to the pressure and temperature of the circulating cooling medium.
