Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a radiant air conditioner that adds the functionality of a radiant air conditioner to a conventional air conditioner. Concerning the conversion unit.

[Conventional technology]

Radiant heat environments using concrete slabs or mortar ceilings as heat carriers, i.e. floor heating, Well radiant heating and ceiling radiant cooling are suitable for Japan's climate, which is hot and humid in the summer and cold and humid in the winter. It can be said that it is a heating and cooling system. For radiant heating that does not rely on air conditioning, the building Floor radiant heating has been widely adopted since ancient times, depending on the purpose and form of use. The internal thermal environment is highly valued.

0003 Ceiling radiant heating was developed in Europe a long time ago by radiating heat from the condensed water of steam heating. The purpose is to easily drain water using gravity (without using a vacuum pump etc.) In many cases, condensate water pipes are installed in a meandering manner within the well. With ceiling radiant cooling, the indoor heat load The feature is that sensible heat load and latent heat load are treated separately. First, the sensible heat load is It is removed by the heat absorption effect on the ceiling cooling surface, and water vapor generated from the human body and latent water vapor from infiltrated air are removed. The heat load is removed with a dehumidifier. In addition, in air conditioning using an air heating medium, both the sensible heat load and the latent heat load are the same. It is characterized by the fact that it is treated with cooled (superheated) air at the same time.

0004 As a conventional example, an air conditioner using an air heat medium as shown in FIG. 2 will be described first. In this conditioner, air is taken in by fan 2 from suction port 1, and air is drawn in horizontally. send to. The airflow is cooled by the cold (warm) heat from the cold heat source 3 in the heat exchanger 4. (heated). The cooled (heated) airflow is then blown out from the air outlet 5. , air is used as a heat medium to cool and heat the room.

[0005] Next, a conventional radiant heating and cooling system as shown in FIG. 3 will be described. cold heat The cold water or high temperature condensed water obtained by heat exchange from the source 13 is sent to the ceiling 14 or the floor 15. The water flows into the embedded heat radiation pipe 16 in a meandering manner. In addition, the ceiling 14 or floor 15 is insulated. The upper part of the ceiling and under the floor are insulated by material 6. Ceiling 14 or floor by heat sink 15 is cooled (heated) and its temperature decreases (increases). At that time, ceiling 14 and floor 1 Radiation occurs from 5 and cools and heats the room. In addition, humidity is controlled by a moisture-proof device and a humidifier 17. Adjust. However, such equipment does not cover ceilings, floors, or other areas throughout the building. Therefore, installation is difficult unless consideration is given from the design stage.

[0006]

[Problem that the idea aims to solve]

Air conditioning systems that use air as a heat medium, developed mainly in the United States, produce high temperatures in the summer like in Japan. It cannot be said that it is comfortable in a climate with high humidity and low temperature and low humidity in winter. air heating medium air conditioning In Japan, unless you install a humidifier in the winter, the room will be dry and the humidity will be 40%. The following is true. In summer, cold water of 5 to 10 degrees is usually required for dehumidification, and indoor The dehumidification effect will not occur unless the temperature is below 15 degrees, so the room temperature will be below 23 degrees. . Furthermore, the current air heating medium, which inevitably involves airflow movement and temperature differences between the top and bottom of indoor air, Convection type air conditioning cannot be said to be comfortable for people who stay in the room for a long time, and it is not the best from a health standpoint. No.

[0007] On the other hand, radiant heat environments, namely floor radiant heating, ceiling radiant heating, and ceiling radiant cooling, This can be said to be a heating and cooling system suited to Japan's climate. However, this heating and cooling system Since the system is a facility that spans the entire building, it is important to design it on the ceiling and floor from the building design stage. If you do not do so, it will be difficult to install it later.

[0008]

[Means to solve the problem]

The present invention was developed in view of these points, and it There is a communication path connecting the outlet and the intake port, and air flowing through the communication path is provided in this communication path. A heat exchanger that exchanges heat with air, and a radiant panel that is thermally connected to this heat exchanger. The radiant heating and cooling conversion unit consists of:

[0009]

[Effect] This invention's radiant heating and cooling system converts a conventional airflow type air conditioner that uses air as a heat medium. Easily and efficiently perform radiant heating and cooling by connecting units. becomes possible.

【Example】

Figure 1 shows the radiant heating and cooling conversion unit of this invention installed on the ceiling with four slit-shaped air outlets. It is connected to a conventional indoor air conditioning unit (Figure 2) that has an opening. Ma In addition, Fig. 4 shows the radiant heating/cooling conversion unit of the present invention, and Figs. 5 and 6 show their cross-sectional views. vinegar.

[0011] In such indoor air conditioning units incorporating radiant heating/cooling conversion units, The airflow blown out from the airflow outlet 1 of the indoor air conditioning unit is converted into radiant cooling/heating. The airflow is taken in from the unit's airflow intake port 7 and assembled into the radiant heating/cooling conversion unit. It passes through a heat exchanger 8. At that time, the cold (warm) heat possessed by the airflow is transferred to the heat exchanger 8 side. hand it over to The cold (warm) heat is guided to the radiant panel (9) connected to the heat exchanger 8. to lower (raise) the temperature of the radiant panel 9. And this cooled (heated) radiation Cooling (heating) is performed by the radiation effect from the panel 9.

0012 This radiant panel 9 is made of iron whose surface has been oxidized to increase the emissivity. glazed porcelain, white paper, fused quartz, polished marble, rough red brick, smooth Cover the surface with kana glass, hard glossy rubber, black lacquer, electrolytic graphite, etc. Ru. In this way, the surface-treated radiant panel 9 is installed directly on the ceiling surface. Since this is not aesthetically pleasing, a slit 10 is provided at the bottom of the radiant panel 9 to allow direct access. The radiation panel 9 is made invisible.

[0013] On the other hand, the airflow that has passed through the heat exchanger 8 in the radiant heating and cooling conversion unit is The airflow passes through passages 12a to 12d and reaches the airflow inlet 1 of the conventional indoor air conditioning unit. , is again drawn into the conventional indoor air conditioning unit and transferred to the heat exchanger 4 by the fan 2. sent to. When the airflow passes through the heat exchanger 4, the cold (warm) heat from the external cold heat source 3 is converted into cooling (heating) airflow by Then, from the airflow outlet 5 again It is blown out and taken into the radiant heating/cooling conversion unit. In this way, conventional Conventional indoor air conditioning units can be used without blowing cold (warm) air into the room during indoor air conditioning. Since heat is transferred in a closed circuit within the radiant heating and cooling conversion unit, This makes it possible to minimize losses.

[0014]

[Effect of the idea]

According to the present invention, conventional indoor air conditioning that uses air as a heat medium can be used to reduce thermal energy loss. It is possible to change to radiant air conditioning in minimal conditions. In addition, the previous convergence Unlike injection heating and cooling systems, it is installed additionally on air conditioners that use air heat medium, so It can be installed relatively easily.
