Description

  The present invention relates to a ceiling radiant panel mounting structure and a mounting method that are arranged on the ceiling of an air-conditioned room in various buildings such as hospitals, elderly facilities, and libraries.

  Conventionally, as an air conditioner installed indoors, a heat medium such as cold water or hot water is passed through a fan coil, air is cooled or heated by the fan coil, and the resulting cold air or warm air is forced by the fan. The mainstream was the so-called forced convection air-conditioning that circulates and cools the room indoors. In this cooling and heating by forced convection air conditioning, the local airflow called the draft gives too much thermal sensation to the human body, resulting in a loss of comfort or noise caused by a fan that forcibly generates airflow. There is.

  Therefore, as an air conditioning system for controlling the temperature of the room, for example, as shown in FIG. 15, a radiating panel 101 disposed on the ceiling of the room R and a surface that runs along the surface of the radiating panel 101 are provided. A heat medium flow path made up of the pipe 102, and the heat medium is circulated in the heat medium flow path to cool or heat the radiating panel 101, and the radiation panel 101 and the human body directly radiate. There has been proposed an air conditioning system using a so-called radiant air conditioning system in which the room R is cooled and heated by performing heat exchange (see, for example, Patent Document 1). According to the air conditioning system using radiant air conditioning as described above, air conditioning is performed without forcibly generating airflow, which can eliminate the problems of discomfort and noise caused by the draft. Compared to the above, even if the temperature of the heating medium is set closer to the outside temperature (that is, the cold water is set to a higher temperature and the hot water is set to a lower temperature), a sufficient cooling / heating effect can be obtained. There is also an advantage that it can be.
