Abstract

<P>PROBLEM TO BE SOLVED: To provide an entire air type improved radiation air-conditioning system capable of making a living room to a comfortable space by a composite effect of radiation effect and convection effect by increasing the radiation effect while keeping an air flow in a living room at a speed never felt by a person, never disturbing the viewing through a window by dispensing with arrangement of another air conditioner for air-conditioning at the window, and providing a high energy-saving effect with calmness and a low facility cost. <P>SOLUTION: To obtain the comfortable space without making the person feel the air flow in the living room, means for increasing the radiation effect and reducing the air flow velocity are used. Supply air flows in parallel to a floor surface and a wall surface generated in an air conditioner are supplied to a double wall space and collided to a semicircular air flow collision device to generate a turbulence, so that the heat of the air flows is efficiently transferred to a wall material to obtain large radiation from the floor and the wall surface, and the air flow after collision is blown into the living room. According to this, the problem can be solved by the composite effect of radiation effect and convection effect. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

The present invention provides a comfortable air-conditioned space by a combined effect of radiation and convection by supplying cold air and hot air-conditioned air generated by an air conditioner to the floor and wall space. A half-moon-shaped airflow collider is attached to the floor back surface and the construction material on the back of the wall toward the airflow sent to the wall space under the floor, and the collided airflow is collided with the back of the floor back wall again to destroy the boundary film. This system efficiently cools and heats the floor surface and wall surface to obtain a large radiation effect from the floor and wall surface. Energy saving due to the radiation effect is widely known from the past because it is directly radiated to the human body without cooling and heating the air.
Cold air and warm air generated from the air conditioner are sent to the wall space under the floor, and the floor surface is cooled and heated, and then the air flow is sent from the floor outlet 6 at the window and the wall outlet 6 at the edge of the room to the room. The air is blown by R, the room R is cooled and heated, and then returned to the air conditioner to complete the circulation. In other words, the combined effect of the radiation effect from the floor and the wall surface and the convection effect from the floor and the wall outlet 6 makes it possible to obtain an extremely comfortable air-conditioned space with good temperature distribution without feeling airflow.

    An underfloor air conditioning system similar to the conventional system is composed of a floor blowing type air conditioner 2, a floor structure 1, and a floor blowing outlet 6, as shown in FIG. Therefore, air conditioning air is blown into the room 6 and air conditioning by the convection effect is mainly performed and the radiation effect is small. Therefore, the room 6 has a disadvantage that it is uncomfortable because it partially feels the air flow. There is also a system called air replacement type in which air permeable carpet is spread over the entire floor and air-conditioned air is blown out from the floor on the entire floor, but there is not much discomfort due to the convection effect because the blowing speed is slow during heating and heating. During cooling and cooling, there is a problem that a cold airflow is felt at the feet and it is quite uncomfortable. In addition, since the air conditioner 2 is different from the normal air conditioner in the blowing temperature, the air volume, and the static pressure, there is a disadvantage that a dedicated air conditioner is necessary and it cannot be used as a room of another air conditioning system.

    In addition, the above system often has the inconvenience that a circular 200-300Φ floor outlet 6 is often attached to the side of the chair, and it must be relocated due to discomfort caused by airflow. In the other system, there is a problem that an air permeable carpet laid on the entire floor surface is clogged with dust due to long-term use, and air blowing is worsened. Further, as shown in FIG. 4, there is a disadvantage that a separate dedicated air conditioner is required at the window, and the equipment cost is increased.

  The problem to be solved by the present invention is that the air flow rate in the air conditioner is reduced by eliminating the floor air outlets 6 in the living area except for the windows, so that only the radiation effect can be obtained, because the air flow velocity in the room must be 0.5 m / sec or less. Such a problem that the pressure is reduced and the blowout temperature is the same as that of a normal floor air conditioner. In addition to the air conditioning of the living room R part, a system that does not require a separate air conditioner as a countermeasure against the cold draft especially at the window part. There is no system that can solve all of these problems and has a lower equipment cost.

The present invention has been made paying attention to such points, and the object of the present invention is to provide a quiet and safe radiant air-conditioning system with a simple configuration, low manufacturing cost, drastically reducing operating expenses. It is to provide.
In order to obtain a comfortable space with an indoor air flow velocity of 0.5 m / or less, it is necessary to have a sufficient radiation effect without providing an outlet on the floor surface. Underfloor blowing type air conditioner 2 or a combination of a normal air conditioner and a short duct, the air flow generated by the air conditioner is sent to the underfloor air supply space or the air supply space in the wall, and the back of the floor and the back of the wall the attached one per 1 m ^2, with semicircular air flow impactors 3, efficiency collide again conditioned air stream flowing in parallel to the floor or wall by converting vertically in this air flow impactors into the floor back surface or the wall back surface Because it cools and heats well, a large radiation effect is obtained from the floor or wall surface. Further, in the living room R, a blower outlet 6 is attached to the window in the case of a floor surface, and a blower outlet 6 is attached to a corner portion or the like in the case of a wall surface. The room R becomes a very comfortable space due to this combined effect of gently blowing convection in the room, and when this outlet 6 is mounted at a height of about 2 m, the S part of the room becomes a non-air-conditioned space, The actual air-conditioned space is narrowed, and the air-conditioning load is greatly reduced, resulting in significant energy savings.

    By adopting the above system, there is no outlet 6 at the window other than at the corner of the wall, so that the air flow rate in the room R can be 0.5 m / sec or less, and no airflow is felt. Although it is a combined effect of radiation effect and convection effect, in the case of only convection effect, both the cooling mode and heating mode are uncomfortable because the temperature near the floor surface is low due to the characteristics of convection. The underfloor air conditioning system requires an air conditioner 10 dedicated to the air conditioning treatment at the window. In this system, the air flow after floor cooling and heating from the floor outlet 6 is necessary. Since it prevents the intrusion of hot air in the summer and unpleasant cold drafts in the summer, the room R is clean and does not obstruct the landscape from the window. In addition, the radiation effect and non-air-conditioned space are also great.

In order to achieve such an object, a half-moon-shaped airflow impactor such as 3 in FIG. 1 is made using a metal or resin material such as stainless steel, as shown in FIGS. A round hole is opened in the construction material on the surface of the wall and attached in the direction in which the airflow collides. Parallel airflow flowing under the floor and in the wall is collided with this airflow collision device to destroy the boundary film, and the floor surface and wall surface are efficiently Cooling and heating to obtain a large radiation effect, and the airflow after the collision is blown gently into the living room R by installing a metal / resin outlet 6 at the window or corner of the wall to obtain a convection effect. An extremely comfortable space that does not feel airflow can be created. Furthermore, even if the room air temperature setting is 2 degrees Celsius due to the radiation effect, the same sensation as with normal air conditioning can be obtained even if it is high in the cooling mode and low in the heating mode. From the experimental results, the radiation effect is about 2 m on the floor surface. Since 2.3 m is the effective range, if the return inlet suction grill 8 of the convection air conditioning unit is attached to a height of 2 m and the space above this height is a non-air-conditioned space S, Compared to a large energy saving.
As for the radiation effect from the wall surface, if the outlet device 6 from the wall corner is mounted at a height of about 2 m as shown in FIG. 5 and the suction port 8 is also mounted at a position of 2 m, the non-air-conditioned space S is created by the radiation effect and the convection effect. Because it comes out, the same effect as the case of the floor surface can be obtained.

  In the case of floor radiation and blow-out type, an air conditioner is installed as shown in Fig. 3-2, and a double floor space is created by the floor structure materials 1 and 5 and the support material 4. After the completion of pasting, the airflow collider 3 is aligned with the direction of the airflow and a round hole is opened in the plywood 5 to attach the airflow collider 3, and the floor finish 1 is pasted on the upper surface. When the generated airflow is sent to the underfloor space from the air supply port 9 and proceeds in a horizontal flow and collides with the airflow collider 3, this airflow causes turbulence, and the film on the back surface of the lower laminated plywood 5 is destroyed and the heat of the airflow Is efficiently transferred to the plywood 5, and further, heat is transferred from the plywood 5 to the finishing material 1 to cool and heat the floor surface, and the room R has a large radiation effect. The floor surface materials 5 and 1 are cooled and heated. Airflow is gently blown out into the room R from the floor outlet 6 attached to the floor near the window, and returns to the air conditioner 2 with the effect of convection. A very comfortable space that does not feel the air flow in the combined effect of convection effect.

  In the case of wall radiation and blowout, the air conditioner is installed in a machine room or the like as shown in FIG. 5-2, and air generated by the air conditioner is sent from the air supply port 9 on the lower surface of the double wall through the duct 16. In the double-wall structure of 2, the airflow traveling parallel to the wall surface material 1 collides with the half-moon-shaped airflow collider 3 in this space to cause turbulence, and the airflow is efficiently generated by the film breakage on the back surface of the wall constituent material 5 The surface material 1 further cools and heats the finishing cloth 11 to obtain a large radiation effect on the living room R. The air flow that cools and heats the wall surface is gently blown out from the wall outlet 6 to the living room R. A convection effect is obtained and the air conditioner 2 returns from the indoor air return port 8 through the return duct 15. The living room R becomes a very comfortable space that does not feel airflow by obtaining a combined effect of the radiation effect and the convection effect. Compared to a conventional building, the ceiling height of the living room can be increased even in a building with a low floor height, and a comfortable living space can be obtained and the construction cost can be reduced.
