Circulating air exchange fan system

Abstract

The invention discloses a circulating air exchange fan system, which comprises an air feeding pipe, an air discharging pipe, an air feeding port, an air discharging port, an air feeding pipe valve and an air discharging pipe valve. The air feeding port and the air discharging port are respectively connected with the air feeding pipe and the air discharging pipe, the air feeding pipe and the air feeding port form an air feeding pipeline, the air discharging pipe and the air discharging port form an air discharging pipeline, and the air feeding pipeline and the air discharging pipeline form an air exchange channel; a circulating air duct is connected between the air feeding port and the air discharging port or between the air feeding pipe and the air discharging pipe, the air feeding port, the circulating channel and the air discharging port form a circulating channel, and the circulating channel is provided with a circulating channel valve; and the air feeding pipe valve, the air discharging pipe valve and the circulating channel valve are driven by a motor and are connected with the power output shaft of the motor through a linkage mechanism, and the linkage mechanism adopts a sprocket/chain linkage mechanism. The circulating air exchange fan system has a simple structure and good use effects and can be operated easily, and the switching of indoor air circulation and indoor-outdoor air exchange of the high-temperature aging room can be realized through one set of air exchange mechanism.

Description

technical field [0001] The invention relates to a ventilation system, in particular to a circulating ventilation blower system. Background technique [0002] The aging room, also known as the burn-in room, is a simulation room for high-performance electronic products (such as computer machines, monitors, terminals, automotive electronics, power supplies, motherboards, monitors, and switching chargers, etc.). A high-temperature, harsh test environment equipment is an important experimental equipment to improve product stability and reliability. This equipment has been widely used in power electronics, computers, communications, biopharmaceuticals and other fields. [0003] The indoor circulation and ventilation function of the aging room is an important link to ensure the smooth progress of production. The indoor circulation and ventilation systems used in many aging houses need to rely on two sets of fans, namely the circulation fan and the ventilation fan, which not only i...

AI Technical Summary

Problems solved by technology

The indoor circulation and ventilation systems used in many aging houses need to rely on two sets of fans, namely the circulation fan and the ventilation fan, which not only increase the number of indoor heat sources, complicate the operation, but also increase the number of pipelines, which is time-consuming and laborious to install, which is very inconvenient , while increasing production costs
