Controlling device for air conditioner of base station

Abstract

The invention provides an automatic controlling device for an air conditioner of a base station. The device comprises a main fan, an external fan, a compressor and an electrical heating pipe of a refrigerating system of the air conditioner, and a temperature sensor, wherein an output end of the temperature sensor is connected with an input end of a programmable logic controller (PLC); an output end of the PLC is respectively connected with input ends of an electric air valve and a contactor; and a contact of the contactor is respectively connected with the compressor, the external fan and the electrical heating pipe. The device can start the related equipment for refrigerating, ventilating or heating through the PLC according to comparison between a real-time detected temperature and a set temperature and an outdoor temperature, so that the energy consumption is saved, and the service life of the air conditioner is prolonged. The running condition of the air conditioner in the base station can be mastered in real time by a monitor, and a control command can be sent out in real time, so that the remote monitoring on the air conditioner of the base station can be realized, and the air conditioner can automatically deal with various working conditions and run normally in an unmanned operation environment.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an automatic control device for base station air conditioners. [0002] Background technique [0003] At present, China Mobile, China Unicom, China Telecom communication base stations, high-speed railway base stations, microwave satellite ground stations, computer rooms, etc. are generally in the state of unattended automatic operation, and various electronic equipment in the base stations are in continuous working state all year round. In addition, the base station is usually designed to be in a sealed state, so the heat energy generated by various electronic equipment during operation must accumulate in the base station room. In order to maintain the normal operation of the equipment, the heat must be exchanged outside the base station with the help of a dedicated air conditioner. The electrical cabinet air conditioner adopts the principle of phase change refrigeratio...

AI Technical Summary

Problems solved by technology

[0004] However, the existing base station air-conditioning technology generally uses the air conditioner directly for sealed refrigeration to achieve the purpose of indoor and outdoor heat exchange of the base station, which requires long-term operation of the air conditioner, but the base station is unattended. , the air conditioner is still on

Turning on the air conditioner for a long time will not only shorten the mechanical life of the air conditioner, but also consume a lot of energy in vain.
