Description

The present invention relates to an air conditioning system, and more particularly to an air conditioning system that air-conditions a target space using a heat medium for radiant air conditioning.

Conventionally, as an air conditioning system installed on the floor of a building, a base in which a groove for fitting a heat medium flow path is formed, a heat medium flow path through which a heat medium such as cold water or hot water flows, and a heat medium installed in the base. Floor radiation panels have been proposed that provide a radiation plate that protects the flow path and radiates heat. The base of this floor radiating panel is formed with a plurality of ventilation holes for blowing air into the air-conditioned room so as to escape from the bottom of the groove to the bottom of the floor, and the air wraps both sides of the heat medium flow path from the bottom of the base. It is configured so that it flows in this way, exchanges heat with a heat medium, and is blown out to an air-conditioned room (Patent Document 1).

In addition, as another air conditioning system, a long heat transfer plate that holds a cold / hot water pipe that allows cold water or hot water to pass is fixed on a support leg erected on the slab, and the heat transfer plate is also fixed. A plurality of cover plates are joined on the top, and a plurality of panel boards having the same length as the cover plate and having a cooling / radiating effect are joined and continuously provided on both sides of each cover plate, and further, a heat transfer plate is provided. , The cover plate and panel board are tightened and fixed to the upper surface of the support legs with tightening bolts to form a floor panel. A floor panel device provided with a space portion that also serves as a setting space has been proposed (Patent Document 2).

Further, in recent years, from the viewpoint of cost reduction, an air conditioning system has been adopted in which the building has a reverse beam structure to expose the ceiling slab of the skeleton and radiate air conditioning from the ceiling slab of the buried pipe type. This air-conditioning system has a configuration in which radiant air-conditioning pipes are laid on the upper surface of the ceiling slab, that is, in the underfloor space provided between the concrete slab and the floor, and the radiant air-conditioning pipes are buried in lightweight concrete such as cinder concrete. The heat and cold of the radiant air-conditioning pipe is radiated to the target space on the lower floor directly below via lightweight concrete and the reverse beam slab, and the target space on the lower floor is air-conditioned. Further, on the upper surface of the lightweight concrete in the underfloor space, a plurality of electric wirings for supplying electric power to various electric powers and equipments arranged on the floor are laid.

However, in the air conditioning systems of Patent Documents 1 and 2, there is a problem that the material cost and the construction cost increase because the floor panel structure for installing the radiant air conditioning pipe is complicated and the installation work is complicated. In addition, the structure of the building must be reinforced as the load increases due to the base, which results in a decrease in workability due to the structure reinforcement and an increase in material cost and construction cost required for reinforcement.

In addition, in the above-mentioned air conditioning system adopted in recent years, it is necessary to additionally cast lightweight concrete for burying the radiation air conditioning pipe separately from the structural concrete, and the workability is low, and the material cost and construction required for the additional casting are low. The cost increases, and the structure of the building must be reinforced due to the increase in load due to the lightweight concrete, which further reduces workability, increases the material cost, and the construction cost. Accompanied by an increase in.

In addition, the heat of the radiant air conditioning piping arranged in the underfloor space of the floor is radiated from the lower surface of the reverse beam slab on the floor, that is, the lower surface of the floor slab concrete, but due to the influence of heat storage in the thick floor slab concrete, etc. , It takes time for the radiant air conditioning to start working in the target space on the lower floor directly below (the time required for the target space to reach the set temperature after supplying the heat medium to the target space), and the responsiveness of the radiant air conditioning. There is room for improvement in terms of energy efficiency and comfort.

Furthermore, since the air conditioning of the lower floor directly below is performed using the radiation air-conditioning piping installed in the underfloor space of the floor, the underfloor part of the floor is not a little thermal when air-conditioning the lower floor directly below. In a building used for renting floors, it is difficult to adjust the appropriate temperature for each target space on the upper and lower floors in order to obtain a comfortable temperature.

In addition, since it is necessary to raise the electrical wiring laid in the lower part of the underfloor space to the floor panel of the floor concerned, the electrical wiring of the length corresponding to the length from the upper surface of the lightweight concrete to the floor panel is provided. Extra wiring is required, which increases the material cost and construction cost required for wiring.

An object of the present invention is to provide an air conditioning system capable of improving energy efficiency and comfort by realizing excellent responsiveness of radiant air conditioning while realizing cost reduction.

It is possible to reduce the material cost and construction cost required for additional casting of lightweight concrete.

Further, since the mesh panel 30 and the heat insulating material 40 are much lighter than the lightweight concrete, the increase in load due to the installation of the mesh panel 30 and the heat insulating material 40 is very small, and the structure reinforcement of the building 100 is reinforced. It is not necessary or a little structural reinforcement is sufficient, it is possible to prevent a decrease in workability due to the structural reinforcement, and it is possible to prevent an increase in material cost and construction cost required for reinforcement.

Further, since the heat from the pipe 50 installed in the underfloor space S2 on the predetermined floor causes radiant air conditioning of the floor through the floor panel 10 above the floor panel 10, the heat from the pipe directly under the floor slab below the floor slab. Compared to the case of performing radiant air conditioning on the lower floors, the heat storage in the floor slab 103 is extremely small, the rise time until the radiant air conditioning starts to work in the target space S1 on the floor is shortened, and the excellent response of the radiant air conditioning. It is possible to realize the property and improve energy efficiency and comfort.

Further, since the pipe 50 installed in the underfloor space S2 of the floor is used to perform radiant air conditioning on the floor and the lower floor immediately below the floor is hardly affected by heat, the building 100 is used for renting the floor or the like. Even if this is the case, it is possible to adjust the appropriate temperature for each target space on the upper and lower floors in order to obtain a comfortable temperature on the floor of the target space.

Further, the support 20 has an engaging portion 24 which is provided on the upper end side of the support 20 in the longitudinal direction and engages with the mesh panel 30, and the mesh panel 30 is close to the floor panel 10. Since it is installed, the thickness of the air layer between the pipe 50 and the floor panel 10 is small, heat transfer in the thickness direction in the air layer is quickly performed, and heat is quickly radiated from the upper surface 10b of the floor panel 10. Therefore, better responsiveness of radiant air conditioning can be realized.

Further, since the engaging portion 24 is a flange portion that engages with the mesh panel 30, the mesh panel 30 can be easily engaged with the engaging portion from any of the four sides of north, south, east, and west, improving workability. can do.

Further, since the electric wiring 60 for supplying electric power to the electric equipment in the building 100 is laid on the heat insulating material 40, when the electric wiring 60 is raised up to the floor panel 10 on the floor and wired, the electric wiring 60 The start-up length can be shortened, and the material cost and construction cost required for the start-up wiring can be reduced.

Although the air conditioning system according to the above embodiment has been described above, the present invention is not limited to the described embodiment, and various modifications and changes can be made based on the technical idea of the present invention.
