Description

Waterway type cooling system in building}

The present invention relates to a building cooling system, and more particularly, to a waterway-type building cooling system installed in a waterway-type rainwater flow device inside a building wall to vaporize during rainwater flow to lower the air temperature inside the building.

Buildings such as skyscrapers and apartments consume a lot of electrical energy for cooling in summer.

In particular, as the number of lighting devices used in the building increases and the use of office equipment such as computers and copiers increases, the cooling of the interior of the building is not limited to the summer season and continues to be performed throughout the year. As a result, energy consumption (cooling load) for cooling the building continues to increase.

In addition, one of the important reasons for increasing the cooling load of such buildings is the radiant heat of the sun. In other words, solar radiation causes a lot of external heat energy to be applied to the building, which heats up the interior of the building and increases the cooling load of the building.

Therefore, in order to reduce the cooling load of the building, it is very important to effectively block the radiant heat of the sun transmitted to the building.

In recent years, the government and industry are moving faster to conserve the environment and develop eco-friendly technologies due to the rapid rise in energy prices and global warming.

In particular, it is time to develop various eco-friendly technologies, such as water supply facilities, rainwater use facilities, renewable energy use, and energy saving.

In response, the concept of Green Building has recently emerged. An eco-friendly building is a building that is designed, constructed, operated, and demolished in an environmentally improved way. It is designed to be eco-friendly by applying technologies such as energy load reduction, high efficiency energy facilities, resource recycling, and environmental pollution reduction technologies for the purpose of energy conservation and environmental conservation. It is a structure that is designed to minimize damage to the environment even after the life of the building is dismantled after construction and maintenance.

Representative technologies of eco-friendly buildings are technologies to reduce energy load and to improve energy efficiency. This is because the use of energy required for the maintenance of buildings, such as heating and cooling of buildings and lighting, generates environmental pollutants.

In addition, environmental pollution reduction technology should be supported to reduce the generation of various sources of pollution from buildings and to minimize the damage to the surrounding environment.In the case of resources that cannot be reused or recycled, It is important to have techniques for handling damages to minimize the risk.

However, in the case of facilities that can save water resources, such as heavy water, there is a disadvantage that the initial cost is increased during the construction of the first building, the installation rate is not very high.

In light of this, most tanks are used to store rainwater that is simply thrown away and flowed into rivers, and tanks for rainwater are stored in schools, public facilities, and homes. It is also used as cleaning water and landscaping water.

In addition to utilizing such rainwater as toilet water, cleaning water, landscaping water, etc., methods for cooling buildings have been proposed, but commercialization is difficult due to installation costs and operational difficulties.

For example, in the case of the installation on the outer wall of the building has the effect of blocking the radiant heat of the outside, it is limited to lower the temperature inside the building.

In particular, since rainwater is used as cooling water in a cooling system using electric energy, there is a limit to view it as an environmentally friendly cooling method.

The present invention is to solve the problems of the prior art building cooling system, by installing a rainwater flow device in the form of a water channel inside the building wall to be vaporized during the rain water flow to lower the air temperature inside the building The purpose is to provide a building cooling system.

The present invention provides a waterway-type building cooling system in which an open waterway type rainwater flow device is installed inside a building wall to lower the temperature inside the building by vaporization and drive a turbine using water vapor generated by vaporization. There is a purpose.
