Air circulation system having circulation and discharge and suction function of indoor air

Abstract

The present invention provides an air circulation system having a circulation, discharge, and suction function of indoor air, comprising: a case; a suction fan; a discharge fan; a heat exchange module; a first drive portion; a second drive portion; a power supply device; and a controller. According to the present invention, an air pipe automatically drives an adjusting device by a program inputtedaccording to a situation sensed by a sensor to control opening and closing of a pipe of a suction port or a discharge port such that the air circulation system can be performed as an air purifier bycirculating only indoor air, or the air circulation system operates in a suction or a discharge mode or is configured to be operable in a suction and discharge mode. Also, according to operation modes, speed and air motion are controlled through turning on / off fans respectively arranged on the lower position and the upper position of a device.

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2016-0102279 filed on Aug. 11, 2016, the entire disclosure of which is incorporated herein by reference. technical field [0003] The present application relates to an air circulation system, and more particularly, to an air circulation system having functions of circulation, discharge and suction of internal air to be used as a An air cleaner to operate in an air intake mode or an air exhaust mode, or to operate in an air intake and exhaust mode. Background technique [0004] Windows installed in buildings allow interior occupants to view the exterior and provide natural lighting to the interior. Windows also ventilate the indoor air when it becomes stale or polluted. These windows are mounted in window frames in the form of sliding windows or hinged windows of certain sizes. When the windows are opened to ventilate the indoor air, the indoor a...

Problems solved by technology

[0008] Second, since the external air inlet and outlet cannot be completely blocked, when the wind is strong and the wind pressure becomes high, a positive pressure is generated, and thus the whistling wind sound is transmitted to the inside through the pipe through the external air inlet and outlet, in serious noise inside

Further, even if the fan is turned on to exhaust the air, it may not be performed properly to allow the air to flow back into the room

[0009] Third, in order to reduce energy loss, since a full heat exchanger is installed to exchange heat between the internal air to be discharged to the outside and the external air to enter the inside, the ventilator needs to be disassembled to replace the heat exchanger, and therefore no Easy maintenance and repair of heat exchangers

Also, it is impossible to replace the heat exchanger with other heat exchangers with different functions and types such as total heat exchanger, sensible heat exchanger, etc. according to the purpose of using the ventilation equipment
