Title:
HEAT-RECOVERY VENTILATION APPARATUS FOR SOLVING CONDENSATION DAMAGE
Document Type and Number:
WIPO Patent Application WO/2023/153732
Kind Code:
A1
Abstract:
The present invention relates to a heat-recovery ventilation apparatus solving condensation damage, and controls first and second indoor-side air supply ports, first and second indoor-side exhaust ports, first and second outdoor-side air supply ports, and first and second outdoor-side exhaust ports to be selectively opened by means of three-way valves, and thus cross-circulates internal air and external air as internal air and external air simultaneously flow while crossing each other through first and second electric heaters. According to the present invention, internal air and external air simultaneously flow into each of the first and second electric heaters and cross each other so that internal air is discharged and external air is supplied simultaneously, internal and external air are simultaneously discharged and supplied so that the circulation time of the internal air and the external air is shortened, and the concentration of polluted internal air can be quickly reduced through shortening of the circulation time of the internal and external air. Particularly, dust or foreign material included in the internal air to be discharged to the outside is filtered out by means of an indoor-side filter so that the problem of environmental pollution caused by the discharged internal air is prevented, dust or foreign material included in the external air to be supplied to an indoor space is also filtered out by means of an outdoor-side filter so that the pollution concentration of the internal air in the indoor space is remarkably reduced, and each of the first electric heater and the second electric heater allows the discharge of the internal air and the inflow of the external air to cross each other so that a large amount of internal air is discharged and a large amount of external air is supplied at the same time, and thus the internal air and the external air are quickly circulated, thereby improving reliability of a product.
