Description

ventilation cleaning system

The present invention relates to a ventilation cleaning system, and more particularly, to a ventilation cleaning system with increased convenience in use.

In general, the air in an enclosed space increases the carbon dioxide content over time due to the breathing of living organisms, which interferes with the breathing of living organisms. Ventilators are widely used to replace polluted air with fresh outdoor air.

Such a ventilation device is configured to include a blower for forcibly blowing indoor air and outdoor air, and repeats the process of discharging polluted indoor air to the outdoor side and sucking fresh outdoor air into the indoor side.

However, when cooling and ventilation are simultaneously performed indoors, the cooled indoor air is exhausted and the hot outdoor air is sucked in, so the temperature of the indoor air rises relatively higher than the cooling temperature, reducing the cooling efficiency. When this is done at the same time, as the heated indoor air is exhausted and cold outdoor air is sucked in, the temperature of the indoor air is relatively lower than the heating temperature, resulting in a decrease in heating efficiency. Therefore, a heat exchanger is installed separately in the ventilation apparatus as described above to allow a heat exchange action to occur between indoor air and outdoor air.
