Wherein, described computer controller and all described air-conditioning unit control connection, in the time that air-conditioning system puts into operation, computer controller is according to the accumulated running time of every unit, automatically start less air-conditioning unit running time, and many air-conditioning units use at interval of certain hour rotation under computer controller control, basically identical running time to ensure each air-conditioning unit, extend air-conditioning system service life.
Above-mentioned industrial and mineral also comprises a unit for subsequent use with outdoor type cubicle-type substation air conditioning system, each described air-conditioning unit and unit for subsequent use are connected on a router by the communication of RJ45 netting twine, described router is electrically connected with the operation screen of peripheral hardware, shows the enforcement parameter of each air-conditioning unit by operation screen display.
Described air-conditioning unit is provided with condensation fan.
Operation principle of the present utility model is as follows:
The air conditioner air outlet of air-conditioning system is finally blown into outdoor air in box-type substation after condensation fan, after Indoor Thermal exchange, discharges air by fresh wind tube.Computer controller, baroceptor and temperature sensor etc. are installed in electric cabinet, computer controller passes through temperature sensor, baroceptor etc. by the indoor real time information sampling such as temperature, air pressure, then compare with predefined atmospheric pressure value (as: 20Pa), thereby control the folding degree of new air-valve.
The beneficial effect of technique scheme of the present utility model is as follows:
In such scheme, computer controller is according to box-type substation internal gas pressure and the comparing result of setting air pressure (as: 20Pa), transformer station's internal gas pressure is maintained in constant scope, when substation gate is opened, effectively stop outside dust storm to enter, improve the security of electrical equipment work in transformer station, and air-conditioning system long service life.
