Heat exchange type ventilation device with bypass and recirculation functions

Abstract

The present invention provides a heat exchange type ventilator having a bypass and a recirculation function capable of preventing the generation of condensation in the entire area inside the ventilator and realizing a recirculation mode of the indoor air to provide a pleasant indoor environment. In order to achieve the above object, heat exchange type ventilator comprises a first exhaust chamber into which indoor air flows; a second exhaust chamber through which indoor air passing through the first exhaust chamber is discharged outdoors; a first air supply chamber into which outdoor air flows; a second air supply chamber through which outdoor air passing through the first air supply chamber is supplied outdoors; and a total heat exchanger for achieving heat exchange between indoor air flowing from the first air exhaust chamber to the second air exhaust chamber (20) and outdoor air flowing from the first air supply chamber to the second air supply chamber, wherein lower sides of the first air exhaust chamber, the second air exhaust chamber, the first air supply chamber, the second air supply chamber and the total heat exchanger are separated by separation plates, thereby forming channels with bypasses.

Description

technical field [0001] The present invention relates to a heat exchange type ventilation device with both bypass and recirculation functions, in particular to a heat exchange type ventilation device with both bypass and recirculation functions: A channel is formed in the lower part of the ventilator to effectively prevent dew condensation, wherein the bypass channel can be used as a bypass flow path for indoor air cooled by outside air and a recirculation flow path for clean indoor air And be used flexibly. Background technique [0002] In ordinary homes and offices, etc., in order to perform indoor cooling and heating according to seasonal changes, cooling and heating devices are provided. Heating air conditioners, boilers, etc. [0003] The indoors of ordinary homes and offices equipped with such cooling and heating devices are kept sealed to improve cooling and heating efficiency. The sealed indoor space will increase the degree of air pollution after a predetermined pe...

AI Technical Summary

Problems solved by technology

This outside air cooling is usually implemented in the spring or autumn seasons and is not used in winter, when the bypass mode is not used, as the air stagnates in the bypass channel, condensation will occur and air pollution will occur at the same time , resulting in the problem of bacterial growth

[0012] In addition, Korean Patent No. 10-0577252 discloses an air cleaning and ventilation system with both air cleaning and ventilation functions. The problem of rising costs
