Abstract

PURPOSE:To enhance the humidity controlling function on the air used for air conditioning by a structure wherein an air layer is provided in a bottomed outer tube, into which an inner tube with through holes over its peripheral surface is inserted, and as well as a water absorbing layer is formed over the inner wall surface of the outer tube or over the outer wall surface of the inner tube. CONSTITUTION:The inner tube 5 with through holes 7 over is peripheral surface is inserted in a composite layer composed of a heat insulating material layer 8 as an outer perpheral surface member and a hygroscopic material layer 9 inside the heat insulating material layer 8. The underground imbedded pipe A consists in insertingly arranging the heat insulating layer 8 inserted by the inner tube 5 as just mentioned above in the bottomed outer tube 1 so as to form an air layer 4 therebetween. By employing said underground imbedded pipe A, the air flowed in from the air layer 4 in rainy season or under moisture-rich atmosphere is dehumidified by touching with the hygroscopic material layer 9 through the holes 7 of the inner tube 5 while ascending in the inner tube 5, resulting in lowering the humidity of the air put to an air conditioning use.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an underground pipe, which is buried in the subfloor of a structure, circulates outside air flowing under the floor through the pipe, and during the circulation, the air is heated by geothermal heat. Regarding underground pipes that are used to heat and cool rooms while circulating them, and have a humidity control effect, the first
The invention of J12 is useful in low temperature periods, and the invention of j12 is useful in high temperature periods.

Hereinafter, this invention will be explained for each invention. In the first E, 1 is an outer cylindrical tube with a bottom, and the inner wall surface of this outer cylindrical tube is lined with a water-absorbing substance 2 to form a water-absorbing layer 3.
An underground pipe A is constructed by providing an air layer 4 therein and inserting an inner cylindrical pipe 5 having a through hole 7 on the circumferential surface.

Note that 6 is a duct connected to the inner cylindrical pipe 5, and this duct is used to guide the air passing through the right duct into the room.

Water is stored and used at the bottom of the underground pipe with this configuration. That is, the water stored at the bottom is sucked up by the water absorption layer 3 and contains water. On the other hand, the outside air descends through the air layer 4 and reaches the inner tube 6.
It passes through the through hole 7 and reaches the inner cylindrical pipe 5. In this process, the outside air flows while coming into contact with the water absorption layer 3 of the outer tube 1 heated by geothermal heat, so the temperature rises, and the air rises through the inner tube 5 and is guided into the room. At this time, since the water absorption layer 31ζ contains water, the air that evaporates due to the vapor pressure and is heated contains moisture.

The above effects are not limited to the above embodiments; for example, the same effects can be achieved even if the water absorption layer 3 is formed on the inner tube 5.

In Fig. 2, a heat insulating material layer 8 is provided on the outer peripheral surface of the bottomed outer cylindrical pipe 1.
Then, the inner tube 5 having the hole 7 is inserted into the surface where the moisture absorbing material HII 9 is provided inside the heat insulating layer 8, and the air layer 4 is formed between the heat insulating layer 8 and the outer tube 1, and the material is buried underground. Configure the included pipe.

However, according to this underground pipe A, during the rainy season or high humidity, air flowing from the air layer 4 passes through the through hole 7 of the inner tube 5 on its way up the inner tube 5 and comes into contact with the moisture absorbing material layer 9. This reduces the humidity of the air that is dehumidified and used for heating and cooling.

In addition, in both FIG. 1 and IJ2, if the material is spirally wound around the circumferential surface of the inner tube or the outer tube, the air flow passage can be increased, and therefore the amount of air humidity adjustment can be increased.
