Description

Building exterior wall system with thermal management function {BUILDING EXTERIOR WALL WITH HEAT MANAGEMENT FUNCTION}

The present invention relates to a building exterior wall system having a thermal management function, and more particularly to a building exterior wall system having a thermal management function that can control the amount of insolation inflow and the air flow in the hollow.

Recently, due to the high-rise and large-scale building, the structure and the outer shell are lighter, and the area of the glass window and the front curtain wall of the building are rapidly increasing because of the openness and the securement of the view. However, single skins using glass materials have poor thermal insulation performance and high thermal permeability, which has the disadvantage of increasing heating and cooling loads, which raises energy efficiency problems.

Therefore, energy-saving measures have emerged as an important factor in the design of buildings in buildings where curtain walls of glass material are used. As a result, a multifunctional jacket system capable of satisfying various functions such as insulation and solar shielding This is urgently needed.

Prior Art (No. 10-2006-0036177) is a concept that adds another envelope at a certain distance in front of an existing building exterior wall, and the outer envelope serves to prevent the weather storm outside the building, and the inner envelope is in contact with the interior of the window. It is a system that enables the inflow of outside air into the room through opening and closing.It is equipped with a awning device, an intake vent and an exhaust port in the space between the two shells, so that the greenhouse effect due to solar radiation or the pressure difference between the outside air occurs in the space between the two shells. Indoor ventilation is induced.

Such a sheathing system is attracting attention in terms of energy saving and environmentally friendly building, and has been proposed as an alternative to energy waste through the skin in buildings with glass curtain walls.

However, the prior art document (No. 10-2006-0036177) has a problem that excessive heat rise due to the sun's radiant heat occurs in the hollow part in the summer and the radiant heat is introduced into the room to increase the use of cooling power.

In addition, the prior art document (No. 10-2006-0036177) does not control the flow of hollow air as required or the temperature change of the outside air or inside. Therefore, there is a problem in terms of energy efficiency because it cannot efficiently use the radiant heat of the sun for heating in winter.
