Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention circulates a cooling heat medium such as cold water or cooling brine in a radiating pipe arranged on a ceiling, and radiates cold heat radiated from the radiating pipe to a cooling target room through a heat radiating plate. By doing so, the present invention relates to a method of constructing a ceiling radiation type temperature control device represented by a ceiling radiation type cooling device for cooling a cooling target room.

2. Description of the Related Art For example, a conventional method for constructing a radiant cooling system for a ceiling is to install a plurality of radiant cooling units in which a radiating pipe and a heat radiating plate are assembled into a panel of a unit size in parallel on the ceiling. In this method, the heat radiating pipes are connected in parallel or in series and connected to the cooling refrigerant supply pipe.

[0003]

However, according to the above-mentioned conventional technique, there is a limit to the size of the radiant cooling unit in terms of transportation and installation work, especially when cooling a large area to be cooled. The number of radiant cooling units is very large, and as a result, there are many connecting portions for connecting the heat radiating pipes to each other on the ceiling. Since the above-mentioned connecting portion becomes the main cause of the leakage of the cooling refrigerant (water leakage when the cooling heat medium is cold water), it is necessary to strictly connect the radiating pipes to each other in order to prevent leakage. As a result, expensive joints have been required, and connection work has been troublesome. An object of the present invention is to provide a construction method capable of constructing a ceiling radiation type temperature control device which is less likely to cause a leakage of a heat medium from a pipe connection portion without increasing cost and lowering workability. It is in.

[0004]

The method of constructing a ceiling radiation type temperature control device according to the present invention is characterized in that a flexible heat radiation pipe for circulating a heat medium is attached to the lower surface of the ceiling of a temperature control target room to radiate heat. A heat radiation plate for forming a surface is attached to the heat radiation pipe on the ceiling in a heat conductive state, and the heat radiation pipe and the heat radiation plate are attached by work from the temperature control target chamber. Then, the mounting of the heat radiation pipe and the mounting of the heat radiation plate by using a mounting fixture having a mounting portion on the ceiling lower surface, a pipe mounting portion for mounting the heat radiation pipe, and a plate mounting portion for mounting the heat radiation plate. Is preferably performed.

[0005]

According to the above-mentioned construction method of the present invention, it is possible to manufacture a ceiling radiation type temperature control device comprising a radiation pipe and a heat radiation plate. A flexible pipe that can be mounted on the ceiling separately from the heat radiation pipe and the heat radiation plate, and can be transported to the construction site in a small size and compact state while being long by winding on a reel as a heat radiation pipe. Since a heat radiation pipe is used, the length of the heat radiation pipe to be placed on the ceiling can be made long, for example, the heat radiation pipe to be placed over the entire ceiling of the temperature control target room can be composed of one heat radiation pipe, The number of pipe connections can be very small. Moreover, since the radiation pipe and the heat radiation plate are both attached to a relatively large temperature controlled room under the ceiling as a work space, the work is easy to perform. Especially when mounting the heat dissipation pipe and the heat radiation plate using the fixture, the number of installation steps can be reduced by using the fixture as the fitting between the heat radiation pipe and the heat radiation plate, and at the same time Since both can be positioned by mounting both, the positioning work can be simplified and the workability can be improved.

[0006]

Therefore, according to the present invention, there is provided a construction method capable of producing a ceiling radiation type temperature control device with good workability, in which the number of pipe connecting portions which are main causes of heat medium leakage can be reduced as much as possible. It is now available. In particular, if it is set forth in claim 2, workability can be further improved.
