Abstract

A ventilation system and a controlling method of such a ventilation system are provided. The ventilation system may exhaust internal air from and draw fresh external air into a designated space. When an outdoor temperature is below a freezing point, some of the internal components of the ventilation system may be damaged due to the low external air temperature. This ventilation system controls operation of a supply fan and / or an exhaust fan based on the temperature of supplied and / or exhausted air to prevent such damage.

Description

technical field [0001] The invention relates to a ventilation system. Due to the respiration of living organisms, the carbon dioxide content of the air in a closed space increases over time, which affects the respiration of living organisms. Therefore, when many people stay in a small space such as offices or vehicles, it is necessary to replace indoor polluted air with outdoor fresh air at any time. At this time, a ventilation system needs to be used. Background technique [0002] In the prior art, only the indoor air is forcibly exhausted to the outside by a single blower. However, in the case where only indoor air is forcibly exhausted by a single blower, cold or hot air in the room is directly discharged to the outside, which is not conducive to energy saving. [0003] In the case of using only one blower, the supply of outside air to the room is performed through a window or a gap in the door or the like. [0004] In this case, since the outside air whose temperatur...
