Problems solved by technology

The main problems in the use of the fresh air system in the small communication room of the base station are: firstly, due to the improper setting and selection of the filter and fan, there is a lot of dust in the room, the filter is replaced frequently, and the air volume becomes smaller after a period of operation, which is uncontrollable Indoor temperature; the second is the lack of proper control system. When temperature failure, filter clogging, fan failure, critical temperature and other conditions occur, the fan and air conditioner are frequently switched, the hardware stability is poor, and the failure rate is high, resulting in system control disorder
These issues result in wasted electricity, increased management and control costs, and increased adverse impacts on environmental emissions

Abstract

The invention discloses a fresh air energy-saving system for a small communication machine room. A fresh air handling unit, an air exhaust unit and an air-conditioner are separately arranged; an accurate monitoring system is added; the fresh air handling unit adopts a G4-level coarse filter and a backward curved-blade type centrifugal fresh air unit; a special air pressure valve and a rotatable efflux nozzle are added; the air exhaust unit adopts an axial-flow type exhaust fan; the monitoring system is provided with a system control board connected with a remote monitoring computer; and the monitoring system can control automatically through a monitor. Therefore, the temperature of the communication machine room is effectively stabilized; the device investment is reduced; the device fault rate is decreased; the service life of the device is prolonged; and the fresh air energy-saving system can be used safely in an energy-saving manner for a long period of time.

Description

technical field [0001] The invention relates to an indoor fresh air system, in particular to a fresh air energy-saving system for a small communication room. Background technique [0002] Due to the rapid development of the mobile communication industry, the distribution of small communication equipment rooms of base stations is becoming wider and wider, and the density is increasing. The main problems in the use of the fresh air system in the small communication room of the base station are: firstly, due to the improper setting and selection of the filter and fan, there is a lot of dust in the room, the filter is replaced frequently, and the air volume becomes smaller after a period of operation, which is uncontrollable Indoor temperature; the second is the lack of proper control system. When temperature failure, filter blockage, fan failure, critical temperature and other conditions occur, the fan and air conditioner are frequently switched, the hardware stability is poor,...
