It is the schematic which shows the thermal radiation system which concerns on embodiment of this invention. It is a principle block diagram of the thermal radiation system shown in FIG. It is a flowchart of the thermal radiation method which concerns on embodiment of this invention.

  Embodiments of the present invention will be described below with reference to the drawings.

  The heat dissipation system of the present invention is used to adjust the temperature of a specific space, and in this embodiment, is used to dissipate heat from the hardware facility data center. Referring to FIG. 1, the heat dissipation system 100 includes an air conditioner 40, a first fan 104, a second fan 114, a first temperature sensor 203, a second temperature sensor 233, and a control module 60. The control module 60 controls the operations of the first fan 104, the second fan 114, the first temperature sensor 203, the second temperature sensor 233, and the air conditioner 40.

  The air conditioner 40 is installed inside a room in which the hardware facility data center is installed, and is used to exchange heat between room air and outside air. The first fan 104 can discharge room air to the outside, and the second fan 114 can suck outside air into the room. The first temperature sensor 203 senses the room temperature and transmits the sensed value of the room temperature to the control module 60. The second temperature sensor 233 senses the outside temperature and transmits a sensed value of the outside temperature to the control module 60. The control module 60 compares the detected values of the room temperature and the outside temperature with a search table stored in the control module 60 to search for a corresponding control command, and uses the control command as the air conditioner 40, the first fan 104, and the second fan. To 114.

  Referring to FIG. 2, the control module 60 includes an arithmetic unit 61, a drive unit 63, an input unit 65, a duration monitoring unit 66 and a storage unit 67, and the drive unit 63, input unit 65, duration monitoring unit 66 and storage unit 67. Are all electrically connected to the arithmetic unit 61. The input unit 65 is used to input control commands corresponding to a plurality of temperature ranges and different temperature ranges, and stores input contents in the storage unit 67. Each temperature range and the corresponding control command are stored in advance in the storage unit 67 in the form of a search table. The arithmetic unit 61 is electrically connected to the first temperature sensor 203 and the second temperature sensor 233, reads the temperature sensed by the first temperature sensor 203 and the second temperature sensor 233, and stores the read temperature in the storage unit 67. Compared with the temperature range of the stored search table, a control command corresponding to the temperature range that meets the conditions is output to the drive unit 63. The drive unit 63 is electrically connected to the air conditioner 40, the first fan 104, and the second fan 114, and controls the operation of the air conditioner 40, the first fan 104, and the second fan 114 according to a control command from the arithmetic unit 61. For example, the rotational speeds of the first fan 104 and the second fan 114 are adjusted. The continuity monitoring unit 66 controls the arithmetic unit 61 to acquire the room temperature T1 sensed by the first temperature sensor 203 and the outside temperature T2 sensed by the second temperature sensor 233 every predetermined time interval and store them in the storage unit 67. After comparing with the temperature range of the stored search table, the control command corresponding to the temperature range that meets the conditions is output to the drive unit 63, so that the continuous monitoring unit 66 stops and the heat dissipation system 100 ends the operation. Until then, keep the heat dissipation in a specific space.

  Hereinafter, the operation principle of the control module 60 will be described with reference to a search table.

  Each temperature range and the corresponding control command are input to the input unit 65 by the above-described search table method. The arithmetic unit 61 reads the room temperature T1 sensed by the first temperature sensor 203 and the outside temperature T2 sensed by the second temperature sensor 233. For example, assume that T1 = 18 ° C. and T2 = 10 ° C. The concrete values of the room temperature T1 sensed by the first temperature sensor 203 and the ambient temperature T2 sensed by the second temperature sensor 233 are compared with values in a preset search table, and T1 = 18 ° C. satisfies T1 ≦ 20 ° C. Corresponding to the condition, T2 = 10 ° C. corresponds to the condition of 5 ° C. <T 2 <20 ° C., the control command for the corresponding air conditioner 40 is OFF, and the control command for the first fan 104 and the second fan 114 is ON. is there. The arithmetic unit 61 transmits the control command described above to the drive unit 63, whereby the air conditioner 40 is turned off and the first fan 104 and the second fan 114 are turned on by the drive of the drive unit 63. In the present embodiment, the heat dissipation system 100 radiates heat from the hardware facility data center using the outside temperature, so that the electric consumption of the air conditioner 40 is reduced.

  Referring to FIG. 3, the heat dissipation method by the heat dissipation system 100 includes the following steps.

  Step S1: The initial temperature value of the air conditioner 40, the temperature range of the indoor temperature T1 sensed by the first temperature sensor 203 and the ambient temperature T2 sensed by the second temperature sensor 233, and the air conditioner 40 corresponding to each temperature range, the first A search table describing control commands for the fan 104 and the second fan 114 is set in advance.

  The initial temperature value of the air conditioner 40 is lower than the temperature at which the indoor hardware equipment is optimally operated. Therefore, the operation time is stopped so that the air conditioner 40 lowers the room temperature.

  Each temperature range and the corresponding control command are input to the input unit 65 by a search table method.

  The step of executing this step and activating the continuous monitoring unit 66 can be executed. After starting the continuous monitoring unit 66, the temperature is continuously read until the continuous monitoring unit 66 is stopped by an external control command, and a corresponding control command is output.

  Step S2: The first temperature sensor 203 and the second temperature sensor 233 are activated, and the control module 60 reads the room temperature T1 and the outside temperature T2.

  Step S3: The control module 60 searches for a corresponding control command from the search table based on the room temperature T1 and the outside temperature T2.

  Step S4: It is determined whether or not the temperature for changing the operating state of the air conditioner 40, the first fan 104, and the second fan 114 has been reached.

  If the temperature which changes the operating state of the air conditioner 40, the 1st fan 104, and the 2nd fan 114 is not reached, it will return to step S2.

  Step S5: When the temperature for changing the operating state of the air conditioner 40, the first fan 104 and the second fan 114 is reached, the operating state of the air conditioner 40, the first fan 104 and the second fan 114 is changed.

  The heat dissipation system 100 adjusts the temperature of the specific space by selecting the first fan 104, the second fan 114, and the air conditioner 40 based on the temperature in the specific space, and uses the external temperature when the external temperature is lower than a predetermined temperature. Then, the temperature of the specific space is lowered and the air conditioner 40 is turned off to save electric energy.

  The heat dissipation method of the heat dissipation system 100 further includes a determination step of determining whether or not to set a search table again. This determination step can be executed before the heat dissipation system 100 finishes operating after executing any one step after step S2. If it is determined that the search table is to be set again, the process returns to step S1. If it is determined that the search table is not to be set again, the next step is subsequently executed. In order to make efficient use of the system, this determination step is increased, and the heat dissipation system 100 is completed, and the necessity of adjusting each data of the search table is found, or the operation is stopped or the power is stopped and the power supply is stopped. In the case of recovery, setting the search table can reduce the influence of starting up the heat dissipation system 100 again.

  The storage unit 67 does not belong to the control module 60 and can exist independently, and information of the control module 60 can be stored as an independent memory.

  Although the present invention has been specifically described above based on the embodiments, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. Of course, the technical scope of the present invention is determined by the appended claims.
