CONSTITUTION:Air supplied from an air feeding duct 7 into an air feeding box 2 under an operation of a fan 6 is blown downwardly from the diffuser 4 of the air feeding box 2 and flows down along a radiation plane 1a of a radiation panel 1. Air blown from the air feeding box 2 is sucked into the air suction port 5 of the air suction box 3 as it is and then a heat exchanging operation is carried out on the radiation plane 1a of the radiation panel 1. At this time, drain on the radiation plane 1a is also pushed by an air flow, flows downwardly and then the air is accumulated in a drain accumulator 15 within the air suction box 3. The heat exchanger air (cold air) is also brought into contact with a drain 14 stored within the air suction box 3 and further heat exchanged there and further the air is blown through an air blowing pipe 9 and a flexible pipe 10 toward an operator 12.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a radiant heating and cooling device used for heating and cooling factories, offices, and the like.

(Conventional technology) Radiant air conditioning systems have recently become popular in offices and conference rooms because they provide a soft sensation of cooling and warmth, with little heat shock, and are highly efficient as they can provide spot heating and cooling. It is increasingly being used for room cooling and heating (``Society of Sanitary Engineers Academic Conference Proceedings J' 88.9988
(see 1).

This radiant air conditioning system can be either a ceiling-mounted type or an upright type depending on the installation mode of the radiant panel (Japanese Patent Laid-Open No. 83-28H28).
However, in ceiling-mounted models, the radiant panel is tilted at a considerable angle (3
(approximately 0°), the radiation area for workers on the floor is substantially reduced, and the radiation effect is weakened. In this respect, special drainage measures are required. Vertical radiant heating and cooling systems are advantageous.

(Problem to be Solved by the Invention) By the way, factory workers generally wear more clothes and work at a greater intensity than office workers, and for this reason, especially with regard to cooling loads, factory workers are less likely to wear office work than office workers. It is significantly larger (4 to 5 times) than that of in-house workers. As a result, when the above-mentioned vertical type air-conditioning system is applied to a factory, although it has a radiant effect compared to a ceiling-mounted type, its cooling capacity is insufficient due to the wood, and its application has to be abandoned. I was in an unavoidable situation.

The present invention has been made to solve the above-mentioned conventional problems, and its purpose is to provide a radiant heating and cooling device that has a large cooling and heating capacity and can achieve an expanded range of application.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides an air supply box that blows air to the top of a radiant panel vertically installed on the floor and an intake box that sucks air. one of the two boxes is provided at the bottom of the radiant panel, the air outlet of the air supply box and the inlet of the air intake box are opposed to each other in a direction along the radiation surface of the radiant panel; It is characterized in that the air outlet of the intake box is configured to open in a direction away from the width radiation plane.

(Function) In the radiant heating system configured as described above, between the outlet of the air supply box and the inlet of the intake box,
By flowing air from top to bottom during cooling and from bottom to top during heating, the air exchanges heat on the radiation surface of the radiant panel, and this heat-exchanged air is blown out from the air outlet of the intake box. The heat transfer effect due to convection is added to the heat transfer effect due to radiation.

(Example) Hereinafter, an example of the present invention will be described based on the male attached drawings.

Figures 1 and 2 show a first embodiment of the present invention configured for air conditioning. In both figures, 1 is a radiant panel, and l is the radiant panel's surroundings excluding the radiation surface 1a. is covered with a heat insulating material (path shown). An air supply box 2 is integrally connected to the upper part of the radiant panel 1, and an air intake box 3 is integrally connected to the lower part thereof. The air supply box 2 has an air outlet 4 at its lower end facing the radiation surface 1a of the radiation panel l, and the air intake box 3 also has an air outlet 4 facing the radiation surface 1a of the radiation panel l.
It has an air intake port 5 at its upper end facing the air. An air supply duct 7 having a built-in fan 6 is connected to the air supply box 2, and the operation of the fan 6 supplies outside air or inside air (hereinafter referred to as
(simply referred to as air) is supplied into the intake box 2. In addition, a guide vane 8 is provided inside the air supply box 2 and is seated on the upper end surface of the radiation panel l, and the air introduced into the air intake box 2 is guided to the air outlet 4 by the guide vane 8. From there, it is blown out downward along the radiation surface 1a of the radiation panel 1.

On the other hand, the air intake box 3 is provided with a blow-off pipe (blow-off outlet) 3 in the center thereof. This blowout pipe 9 has a flexible pipe 1
0 are connected and these extend towards the worker 12 on the floor 11. There is a fan 13 inside the intake box 3.
When the fan 13 operates, air is sucked into the intake box 3 through the intake port 5, and this sucked air flows through the blowout pipe 8 and the flexible pipe 1.
0 to the worker 12. Also provided within the intake box 3 is a drain reservoir 15 for storing drain 14 dripping from the radiation surface 1a of the radiation panel.

One end of the drain pipe 1B is introduced into the drain reservoir 15 by penetrating the lower end of the intake box 3.

The drain 14 stored in the drain reservoir 15 is transferred to the drain pipe 16.
Flows from the open end of the tube to O and is discharged.

Thereby, the drain 14 is always stored in the drain reservoir 14 by a height corresponding to the protrusion of the drain pipe 1B. Further, a leg 17 is provided protruding from the lower end of the intake box 3, and the entire device including the radiant panel 1 is mounted on this leg 17.
It will be installed vertically on 70A11 using In addition,
A pipe 18 (FIG. 2) is connected to the upper end of the radiant panel 1 for supplying and discharging a refrigerant into the panel.

In the first embodiment, the air supplied into the air supply box 2 from the air supply tact 7 due to the operation of the fan 6 is blown downward from the air outlet 4 of the air supply box 2 and It flows downward along the radiation surface 1a.

The fan 13 in the intake box 3 is operated in advance, and the air blown out from the air supply box 2 is directly sucked into the intake port 5 of the intake box 3. Heat exchanged. At this time, the radiation surface l
The drain above a flows downward due to the flow of air and is stored in a drain reservoir 15 in the intake box 3. The heat-exchanged air (cold air) also comes into contact with the drain 14 stored in the intake box 3 and undergoes further heat exchange, and is then blown out toward the worker 12 through the blow-off pipe 8 and the flexible pipe 10. In this way, in addition to radiant heat transfer, cold air is supplied to the worker 12 in spots,
This device can produce sufficient cooling effects even when the cooling load is large.
