Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method and apparatus for air conditioning a building,
For example, the present invention relates to an air conditioning method and apparatus for large-scale buildings such as tennis courts, greenhouses, and industrial buildings.

The problem of properly air conditioning buildings is becoming increasingly important, especially as energy costs continue to rise. For example, most industries use equipment that generates large amounts of heat, making it essential to effectively cool rooms in which such equipment is installed.

In addition, in terms of air conditioning in other types of buildings, such as greenhouses, K-season cultivation requires appropriate humidity and temperature, and it is extremely difficult to satisfy these requirements at the same time. Therefore, it is particularly difficult.

At present, harmonization of industrial buildings is achieved only by ventilating the rooms to reduce costs.

Air conditioning is used only in special cases, such as in electronic industry factories and food factories, but there is a problem in that the cost is high compared to the production amount.

The present invention was developed to solve this problem by utilizing the principle of adiabatic cooling to avoid overheating of the room caused by exposure to the sun and to maintain the desired environmental conditions in the room by allowing air to pass through the room. This is how it was done.

That is, the present invention basically consists of creating a slow flow of air through a wetted porous body with a wide surface, thereby evaporating a predetermined amount of liquid and lowering the room temperature. A harmonization method and apparatus thereof are provided.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Porous overlapping wall 3 inside the building, generally designated 1
is provided corresponding to the side wall 2, is fixed to the side wall along its entire contour, and extends over almost the entire surface of the side wall.

The overlapping wall 3 consists of a known moisture supply device, for example a pipe 4 arranged along the upper edge of the overlapping wall and drilled with holes for draining the water to be collected in a pipe 5 below. It is kept constantly moist by a humidifier. Pumps of known type circulate the liquid continuously in the pipes, so that the overlapping wall 3 is constantly moist.

Thus, external air entering through the windows or openings 6 in the side wall 2 is forced through the porous overlapping wall 3 to enter the interior of the building.

A pipe 7 is arranged corresponding to the ridge of the building, and a known means 8 for exhausting air is connected to this pipe. The air suction effect from the inside of the building by the pipe 7 causes a pressure drop, which causes the opening 6 and the porous overlapping wall 3 to be drawn from the outside.
Air is sucked in through. As this air passes through the holes in the overlapping wall, it evaporates the water in the overlapping wall, thus giving up heat and becoming cooler. That is, so-called adiabatic cooling occurs, and latent heat increases instead of sensible heat, which inevitably leads to a decrease in the temperature inside the building.

The method of the invention provides a number of advantages.

First of all, it is extremely efficient. That is, the flow of air that evaporates the liquid is distributed over a large surface substantially equal to the wall surface of the entire building. Therefore, the passage of air through the pores of the porous wall is slow, which results in higher efficiency.

Moreover, this fresh air flow is evenly distributed throughout the room and does not create localized air currents. This system is non-contaminating, extremely practical, and inexpensive. In particular, if the overlapping wall 3 is made of a translucent material, the effect of improving the distribution of light in the room can also be obtained.

A device implementing the method of the invention can be manufactured at low cost.

This applies in particular to buildings that are already equipped with suction devices for circulating air. In this case, only the cost of equipping the porous overlapping wall, for example a layer of inexpensive fibrous absorbent material, and the necessary water circulation equipment to keep the overlapping wall constantly moist are required.

The greatest advantage is obtained by employing a wide surface porous body extending over substantially the entire surface of the side wall of the building, such as a preferably translucent porous overlapping wall.

It goes without saying that the present invention is not limited to the above embodiments, but also includes various modifications that can be made within the scope of the present invention.
