Description

Ventilation system for buildings {VENTILATION SYSTEM FOR BUILDING}

The present invention relates to a ventilation system of a building, and more particularly, to a ventilation system of a building that can ventilate each household by using an outdoor air supply unit capable of supplying outside air and an indoor ventilation device installed in a plurality of households.

High-rise, high-density, high-insulation, and large-sized households are keywords for recent changes in apartments. As the transition from the rectangular plane of the conventional plate-bearing wall structure to the ramen structure including columns and slabs, residential space, such as polygonal planes with multiple inclinations, is changing more dynamically. In addition, a curtain wall method such as an office building is adopted in a residential building in consideration of the elevation of the entire building, excluding a protruding veranda. These changes have led to many changes in residential cooling and ventilation systems.

First of all, the cooling load increased due to the increase of the exclusive area and the structure of the curtain wall. In the case of high-rise buildings, the occupants cannot open the windows arbitrarily, and due to the densified structure, almost no natural ventilation due to the gap wind can be expected, mechanical ventilation with heat exchangers, etc. is mostly applied. have. In addition, consideration of building drafts previously considered only in commercial buildings, such as the effect of exhaust from the outdoor unit of air conditioners on the adjacent upper floors and the performance of the ventilation system by external static pressure, is essential in residential buildings such as apartment houses. It becomes matter.

Ventilation methods used in apartments include natural ventilation, forced ventilation, and hybrid ventilation, depending on the combination of air supply and exhaust.

Passive ventilation is a method in which the air supply and exhaust is naturally made by the pressure and the temperature difference, and there is a problem that the ventilation amount is changed according to the surrounding environment factors such as the draft and the temperature difference.

Active ventilation is a ventilation method in which the air supply and exhaust air is forcedly exhausted by using a blower. This way, constant and stable ventilation is possible.

Hybrid ventilation is a combination of natural ventilation and forced ventilation, and it is common to take a method of forcibly exhausting air using a blower and naturally supplying air by a pressure difference.

However, the conventional ventilation method using a blower such as forced ventilation or hybrid ventilation has always had the problem that the fan power ratio is increased according to the progressive tax rate to operate the blower at the maximum output for forced exhaust, narrow passages when excessive air flows inflow There was a problem that the noise generated in the interior is transmitted to the room.

In addition, the conventional ventilation method has a problem in that the efficiency of kitchen ventilation is lowered when the kitchen exhaust device is operated for kitchen ventilation, since there is no method of intensively supplying outside air to the kitchen side.
