Description

Air-conditioning incoming call autoboot device

Technical field

The utility model belongs to Time Control Technique field, is about a kind of air-conditioning incoming call autoboot device.

Background technology

For the higher place of temperature requirement, as: telephone exchanger room, TV signal are relayed machine room, network data machine room etc., because these electronic equipment great majority are furnished with stand-by power supply, while incoming call again after power failure, supply line can automatically switch, the automatic open function and air-conditioning on market is not all sent a telegram here, if unmanned while incoming call again after having a power failure, or someone is on duty and forget and open in time air-conditioning, air-conditioning will be can be because of unlatching work automatically after sending a telegram here, this will cause computer room temperature to raise too fast and affects the normal operation of electronic equipment.For this reason, the utility model has designed a kind of air-conditioning incoming call autoboot device, with solve after general air-conditioning incoming call can not autoboot drawback.The circuit structure of this device is simple, repacking easily and not affects heat pump performance, easy to use.

Below describe the correlation technique content that air-conditioning incoming call autoboot device described in the utility model relates in implementation process in detail.

Utility model content

Goal of the invention and beneficial effect: for the higher place of temperature requirement, as: telephone exchanger room, TV signal is relayed machine room, network data machine room etc., because these electronic equipment great majority are furnished with stand-by power supply, while incoming call again after power failure, supply line can automatically switch, the automatic open function and air-conditioning on market is not all sent a telegram here, if unmanned while incoming call again after having a power failure, or someone is on duty and forget and open in time air-conditioning, air-conditioning will be can be because of unlatching work automatically after sending a telegram here, this will cause computer room temperature to raise too fast and affects the normal operation of electronic equipment.For this reason, the utility model has designed a kind of air-conditioning incoming call autoboot device, with solve after general air-conditioning incoming call can not autoboot drawback.The circuit structure of this device is simple, repacking easily and not affects heat pump performance, easy to use.
