Description

Ventilation Insulation System of Building Roof

The present invention relates to a ventilation insulation system of a building roof to double the air-conditioning efficiency of the interior of the building according to the seasonal change by installing the building roof of the building, such as factories, art galleries, exhibition halls, warehouses.

The roof of the building covers the upper part of the outer wall to prevent natural environmental factors such as outdoor temperature, snow, rain, wind, etc. from entering the room, or to block the flow of artificially created indoor air by cooling and heating. .

The roof of the building is recognized as a structural part that has a great influence on maintaining the indoor temperature artificially created by cooling and heating in the interior of the building since it is installed in a location where the solar heat is directly received. Due to the impact loads, the roofs of buildings, such as factories, exhibition halls, galleries and warehouses, which are made of prefabricated lightweight structures, have had a significant impact on maintaining indoor temperatures.

In this regard, roofs of buildings already proposed in various forms and insulation structures are known in relation to roofs installed in buildings such as factories, exhibition halls, art galleries, warehouses, etc., and one of them is Japanese Patent Application Publication No. 55-45971 (1880.3. 31), a channel support supported by a roof beam, a synthetic resin insulation board installed between the channel support, a lower plate installed on the insulation board and supported by a channel support, and the lower plate The roof insulation structure constituted as an upper plate material which is supported by a space | interval while forming a ventilation layer spaced at predetermined intervals in the upper part has been disclosed earlier.

However, such a roof insulation structure is simply configured to block the heat exchange or heat transfer between the indoor and outdoor, resulting in the fact that it does not flexibly respond to the change of the season and adversely affects maintaining the indoor temperature in a certain season. Was done.

More specifically, the roof insulation structure is a synthetic resin insulation plate formed on the lower surface of the lower plate, so that the air stagnated in the ventilation layer between the lower plate and the upper plate has a function of the insulating layer while blocking outside air temperature. .

Therefore, in winter, the hot air stagnated in the ventilation layer is heated by the radiant heat from the solar energy acting directly on the roof of the building, thereby improving the heating efficiency of the interior of the building. In the summer, the hot air stagnated in the ventilation layer by the radiant heat of solar energy heats the inner plate and the synthetic resin insulation plate, which acts as a counter function to lower the cooling efficiency artificially created in the room. Due to the lack of flexibility in responding to external environmental factors, the building has lost its function as a roof insulation structure.

The present invention is a structure that can actively use the environmental factors of the outdoor, by indirect cooling and heating function to the roof of the building, the first to flexibly respond to the change of the season, dramatically improving the cooling and heating efficiency of the room, and secondly The purpose is to provide a ventilation insulation system for building roofs that improves the economics of indoor heating and cooling operations by realizing energy savings through the reduction of artificial heating and cooling loads.
