Machine room energy-saving exhaust control system capable of tracking wind direction automatically

Abstract

The invention provides a machine room energy-saving exhaust control system capable of tracking the wind direction automatically. The system is characterized in that the system comprises a PLC machine, a machine room temperature simulation input signal isolator, a machine room humidity simulation input signal isolator, a station wind direction simulation input signal isolator, a temperature and humidity sensor, an air conditioner on / off state input relay, an exhaust fan on / off and high-low power output control relay, a wind indicator and an air conditioner output control replay. By means of the system, the energy of natural wind can be utilized, high efficiency, energy saving and safety of the machine room exhaust system are achieved, and the machine room exhaust system is kept in the efficient, energy-saving and safe working states in the whole operation process.

Description

technical field [0001] The invention belongs to the field of electronic technology, and relates to an indoor energy-saving and air-exhausting control system, in particular to the design and manufacture of an energy-saving and air-exhausting control system for a machine room that can automatically track the wind direction. Background technique [0002] At present, the exhaust air cooling of the radio and television transmitter room is usually done by installing an exhaust fan on the four walls of the machine room, and installing an air inlet below, so that cold air enters from the bottom of the machine room to cool the transmitting equipment, and the heated air rises naturally. The exhaust fan blows it out from above. This exhaust air cooling method is good in the absence of natural wind, but due to the existence of natural wind, the exhaust fans in some directions must be in the working mode of running against the wind, and the exhaust fans in some directions are in the work...

AI Technical Summary

Problems solved by technology

This exhaust cooling method is good in the absence of natural wind, but due to the existence of natural wind, it will inevitably cause the exhaust fans in some directions to work in the upwind operation mode, and the exhaust fans in some directions are in the downwind operation mode.

In the upwind working mode, because the fluid pressure generated by the exhaust fan is opposite to the natural wind pressure, the load on the exhaust fan increases, and the speed of the exhaust fan decreases, stops, or even reverses, thereby reducing the efficiency and life of the exhaust fan. It is the adverse effect of natural wind on the exhaust system of the computer room

[0003] Therefore, if there is a computer room energy-saving exhaust air control system that can automatically track the wind direction, it can judge the direction of the natural wind, turn on the exhaust fan in the downwind state, turn off the exhaust fan in the headwind state, and use the energy of the natural wind. The high efficiency, energy saving and safety of the exhaust system make the exhaust system of the computer room in a high-efficiency, energy-saving and safe working state throughout the whole process, which will definitely be welcomed by the industry. not present in industrial practice
