The continuous monitoring unit 66 of the arithmetic unit 61 is electrically connected. The input unit 65 is configured to input control command information corresponding to the output of the plurality of temperature ranges and different temperature ranges, and store the input content in the storage unit 67. Each temperature range and corresponding control command information are pre-stored in the storage unit 67 in a lookup table. The operation unit 61 is electrically connected to the first temperature sensor 203 and the second temperature sensor 233 to receive the temperature information sensed by the first temperature sensor 203 and the second temperature sensor 233, and is read. Each of the temperature information is compared with a lookup table stored in the storage unit 67, and a control command corresponding to the temperature range corresponding to the condition is output to the drive unit 63. The driving unit 63 is electrically connected to the air conditioning device 40 and the first diversion fan 104 and the second diversion fan 114, and controls the air conditioning device 40 and the first diversion fan 104 under the command signal of the operation unit 61.

The continuous monitoring unit 66 can control the computing unit 61 to acquire the first temperature sensor 203 to sense the first temperature (indoor) T1 and the second temperature sensor 233 to sense the second temperature (external time) at every predetermined interval. The signal of T2 is repeated and the lookup table stored by the operation unit 61 in the storage unit 67 is compared, and a control instruction corresponding to the temperature range corresponding to the condition is outputted to the driving unit 63 to maintain the continuous heat dissipation of the specific space until The continuous monitoring unit 66 is turned off, and the cooling system 100 is finished.

In the present embodiment, a specific temperature value is given by way of example to introduce a preset temperature interval and a corresponding output control signal, as shown in the following table.

The specific value of the first temperature sensor 203 sensing the first temperature T1 and the second temperature sensor 233 sensing the second temperature T2 is compared with a preset lookup table, and T1=18°C meets the T1≦20°C condition. ; T2=10°C meets the condition of 5°C<T2<20°C, and finds the control command signal corresponding to both conditions--the control command of the air-conditioning device 40 is off, the first diversion fan 104, the second diversion fan The control command of 114 is on. The operation unit 61 transmits the above command to the drive unit 63.

The input unit 65 inputs a preset temperature sensor 203 to sense a temperature range of the first temperature T1 and the second temperature sensor 233 to sense the second temperature T2 and a control signal corresponding to the output.

The step of turning on the continuous monitoring unit 66 can be performed simultaneously while the step is being performed. After the continuous monitoring unit 66 is turned on, the subsequent temperature reading and outputting control signals are continuous loop operations until the external control command causes the continuous monitoring unit 66 to shut down.

S2: The first temperature sensor 203 and the second temperature sensor 233 are activated, and the control module 60 acquires the first temperature T1 and the second temperature T2 information.

S3: The control module 60 searches for a corresponding control command according to the information of acquiring the first temperature T1 and the second temperature T2.

S4: It is determined whether the operating state change temperature of the air conditioning device 40, the first diversion fan 104, and the second diversion fan 114 is reached.

Further, the heat dissipation system 100 may further include a determining step of determining whether to perform the lookup table setting again. The determining step may be set as needed after the execution of any step after the step S2, before the end of the heat dissipation system 100. When the judging step judges that execution is required, the process returns to step S1, and if it is not, the next step is continued. The increase of this step is for the system optimization design, so that the heat dissipation system 100 can be reduced by setting the lookup table when it is found that the data of the lookup table needs to be adjusted at any time or the power supply is restored after a sudden crash or sudden power failure. The effect of restarting the cooling system 100.
