Description

Ventilating System for Building

The present invention relates to a building ventilation system for creating a comfortable air environment in the building.

In recent years, as the energy saving standards of the building sector have been strengthened, the sealing performance of buildings has improved day by day, while the pollution of the air in buildings has been deteriorated by this high sealing performance. It must be exchanged with air to create a pleasant air environment.

Conventional ventilation methods that have been used to improve the indoor air environment to be suitable for human health and hygiene include the opening of windows to introduce outdoor air from the building's windy window and to discharge indoor polluted air to the opposite window. There is a wind ventilation to exchange. However, such wind ventilation has a problem that the indoor temperature changes rapidly after ventilation because the heat energy contained in the indoor air and outdoor air is discharged and introduced as it is. In other words, the heat loss occurs according to the temperature difference and the amount of ventilation (outdoor air inflow), the indoor temperature is rapidly dropped during the winter heating, and the indoor temperature is rapidly increased during the cooling in the summer.

In order to solve the problem of the wind ventilation is a mechanical ventilation system for ventilating while exchanging the heat energy of the air introduced into the room and discharged to the outside.

A general mechanical ventilation system is shown in FIG. As shown, a general ventilation system includes an air supply duct 10, an exhaust duct 20, and a heat exchanger 30. The outdoor air exchanges heat with indoor air from the exhaust duct 20 in the heat exchanger 30 and then is supplied to the room along the air supply duct 10. However, this ventilation system could not expect higher heat exchange efficiency because the heat exchange is made only through the heat exchanger (30).

One of the two flow paths of the integrated duct 50 functions as an air supply flow path and the other as an exhaust flow path. The integrated duct 50 is formed in the structure of the double tube by the inner tube 54 and the outer casing 56 at regular intervals so as to provide a space between the outer circumference of the inner tube 54 and the outer circumference. At this time, the interior of the inner tube 54 is an exhaust passage, the space between the inner tube 54 and the exterior 56 is an air supply passage, and the wall of the inner tube 54 is the heat transfer wall 52. In FIG. 3, the longitudinal cross-sections of the inner and outer facades 54 and 56 are both circular, but the longitudinal cross-sections of the inner and outer facades 54 and 56 may be modified into ellipses, polygons, or the like.

The end of the inner tube 54 constituting the right side of both ends of the integrated duct 50 is exposed to the outside through the right end portion (wall portion) of the outer appearance 56. The exterior 56 is sealed such that a portion through which the inner tube 54 penetrates prevents air leakage by the sealant.

This first embodiment further includes a heat exchanger 70. The heat exchanger 70 includes a housing 72 and a heat exchanger body 74 embedded in the housing 72. The housing 72 is installed on the wall of the building, partly indoors and partly outdoors. The housing 72 has an air supply inlet, an air supply outlet, an exhaust inlet, and an exhaust outlet. In the case of the air inlet and the exhaust outlet, the air outlet and the exhaust outlet are located at the indoor side. The heat exchanger main body 74 is a heat exchange between the outdoor air and the indoor air introduced into the air inlet and the exhaust inlet, respectively.
