Abstract

PURPOSE:To utilize the calorie efficiently and at the same time make the speed of response of the temperature in the discharged air fast by arranging a heating and/or cooling devices for the air near the upstream side at each air discharge port in air channels. CONSTITUTION:Into an air channel 5 air 7 of room temperature is led through an air inlet port 4, and then the air is blown out into a room through air discharge ports (a-d) from the downstreat side to the upstream side successively. At this time the air is heated by respective heaters 6 and discharged as hot air. The air 7 that was introduced flows in the air channel 5, but there are the air that passes through a first stage heater 6 and the air that does not pass through it. The air that passes through the heater 6 is first heated there and discharged as hot air through air discharge ports (a, that are arranged near the downstream side. Because the air until it passes through the heater 6 and the air that does not pass through it are at room temperature, the air that touch the front side wall 1 has no difference in temperature from the trunk bodies such as the floor, ceiling, walls, etc., so that there is no heat radiation (or heat receiving) from the front face wall 1 and back face wall. During cooling said heaters 6 are used as cooling means.

Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an air blowing panel for air conditioning and heating [Background Art] An air blowing panel for air conditioning and heating is installed on the floor, side wall, or ceiling of a building, and the air blowing panel for heating and cooling is installed on the floor, side wall, or ceiling of a building. It is configured to blow out hot air or cold air from a large number of formed air outlet ports for cooling and heating.

FIG. 6 shows a conventional air blowing panel viewed obliquely from above. The panel has a front side wall 3° and a back side wall 31 facing each other with an interval, and these side walls 30.
31 are joined together by lateral side walls 32, 32. This panel is a flat rectangular plate as a whole,
An air inlet 33 is provided at one end thereof, and the interior thereof is hollow and forms an air passage 34 communicating with the air inlet 33. The rear end of the air passage 34 is closed by a chamber wall, and a large number of air outflow ports a to d are arranged on the front wall 30. These air outflow ports a to d are arranged in four stages from the air inflow port 33 side to the stomach wall side, each group having three air outflow ports. Hot air or cold air flows into this panel through the air inlet 33, and the hot air or cold air flows from the upstream side to the downstream side in the air path 34 and is sequentially blown out from each air outlet a% d. It looks like this.

However, in the above panel, hot air or cold air flows in through the air inlet 33, passes through the air passage 34, and directly flows out from the air outlet a to d, so the hot air or cold air flows through the front side wall 30 and the back side. wall 31
It began to exhibit heat dissipation or heat reception through the channel, and as a result, there was a temperature difference between the upstream and downstream sides. That is, in the case of warm air, as shown in FIG. 7, the warm air that enters the air inlet 33 has the highest temperature, and the warm air that is relatively high in temperature also flows from the air outlet a on the most upstream side. flows out.

However, as the hot air flows downstream in the air passage 32, the temperature of the hot air gradually decreases due to heat radiation from the walls, so warm air with a slightly lower temperature flows out from the next air outlet, and this state continues on the downstream side. until it reaches the air outlet d. Therefore, the warm air that has reached the air outlet d on the most downstream side has a lower temperature than the warm air on the upstream side. As a result, the panel surface temperature and the temperature of the hot air blown out are significantly different between the upstream side and the downstream side, resulting in a temperature difference in the air near the panel. These panels can be installed on the floor, ceiling or
When used on side walls, etc., heat is radiated from the back wall of the panel, making it impossible to effectively utilize the amount of heat for room heating. Furthermore, although floors and ceilings have a large heat capacity, as mentioned above, if the degree of heat dissipation is high, most of the heat will be taken away by the floors and ceilings when heating operation starts, and the temperature of the air blown out will rise quickly. There was also the problem of not being able to do so. The above also applies to cold air.

[Purpose of the invention]

In view of the above circumstances, the present invention provides a method for blowing hot air or cold air without any temperature difference from the upstream side to the downstream side,
In addition, the present invention provides an air blowing panel for air conditioning and heating, which suppresses heat radiation from surfaces in contact with the ceiling or walls, effectively uses the amount of heat, and quickly responds to the temperature of the blown air at the start of operation. The purpose is to

[Disclosure of the Invention] In order to achieve the above-mentioned object, the present invention includes an air passage that communicates with an air inlet formed on one side of the panel in the panel, and an air passage that communicates with the air passage on the front wall side of the panel. In a heating and cooling air blowing panel having air outlets arranged from the upstream side to the downstream side of a communicating air passage, an air heating and/or cooling means is provided near the upstream side of each air outlet of the air passage. The gist is an air blowing panel for air conditioning and heating, which is characterized by the arrangement of.

Hereinafter, the present invention will be described in detail with reference to the drawings showing embodiments thereof.

FIG. 1 shows a first embodiment of an air blowing panel for air conditioning and heating according to the present invention, viewed diagonally from above. This panel includes a front wall 1, a back wall 2, and a pair of horizontal walls 3.3, and an air inlet 4 is opened at one end of the panel. 5 is formed. Note that a chamber wall is provided in a portion of the air passage 5 corresponding to the air inlet 4. In the front wall 1, air outlet ports a w d, each consisting of two left and right air outlets, are arranged in four stages from the upstream side to the downstream side of the air passage 5. These air outflow ports a-=d are arranged such that those corresponding to the upstream side are arranged closer to one side of the front wall 1, and as they reach the downstream side, they are closer to the other side of the front wall 1. A heater (heating means) 6 is disposed near the upstream side of each of the air outlet ports a % d so as to be located on the inner surface of the front wall.

Air 7 at room temperature is introduced into the air passage 5 through the air inlet 4.
is being introduced. After the air 7 is introduced into the air passage 5, the air 7 is sequentially introduced into the air outlet a from the upstream side to the downstream side.
-d into the room, and at that time, the air is heated by each heater 6 and blown out as warm air. The introduced air 7 flows through the air passage 5, and some of it passes through the first stage heater 6 and some of it does not. The air passing through the heater 6 is heated for the first time there and is blown out as warm air from an air outlet a disposed near the downstream side thereof. The air that passes through these heaters 6 is at room temperature;
Since the air that does not pass through is also at room temperature, there is no temperature difference between the air in contact with the front wall 1 and the building blocks such as the floor, ceiling, and walls. There is no heat reception). First stage heater 6
The air passing through the air outlet a is always blown out from the air outlet a in the vicinity, and the air that passes through the widthwise line where the first stage air outlet a is located is all at room temperature, and the air that passes through the first stage air outlet a is at room temperature. All of the air that passes through a certain width direction line is at room temperature, except for the air that passes through the heater 6. As a result, the air up to the line where the fourth stage air outlet d is located is normal temperature air, except for the warm air blown out from each outlet a - d, and as mentioned above, the air is radiated to the indoor air and the frame. There's nothing to do. As a result, the amount of heat can be effectively used without loss, and the hot air blown out from each air outlet a to d becomes hot air of uniform temperature heated from room temperature air by each heater 6. I end up bursting into laughter. Furthermore, since there is no heat radiation, no matter how large the heat capacity of the frame is, it will not affect the start-up of the hot air blown out at the start of operation. In the case of cooling, the heater 6 is used as cooling means.

FIG. 2 shows a second embodiment. This embodiment uses a fin-tube heat exchanger 1 as a heating or cooling means.
The one using 0 is hailed. The heat exchanger includes a conduction pipe 11 and fins 12. Hot water, cold water, steam, refrigerant, or the like flows through the conduction pipe 11, and heat is exchanged with air at the fins 12. Each fin 12 is arranged near the upstream side of the air outlet ports a to d.

3 and 4 illustrate a third embodiment. In this embodiment, the interior space of the panel is divided into two by a partition wall 15 disposed between the front wall 1 and the back wall 2, and the partition wall 1
5 and the back wall 2, a series of first holes communicating with the air inlet 4 are provided.
An air passage 16 is formed. A second air passage 17 is formed between the partition wall 15 and the front wall 1, and communication holes 18 are arranged in the partition wall 15 so as to correspond to the upstream side of each heater 19, respectively. From the air inlet 4 to the first air passage 16
The air 7 introduced therein reaches the second air path 17 through each communication hole 18, is heated by a heater 19, and is blown out from each air outlet a-e as warm air. According to this embodiment, the heater 19 is connected to the upper second air passage 1.
Since the air flowing through the first air passage 16 is not heated, the temperature rise in the flow direction is more completely suppressed. The heater 19
is sometimes used as a cooling means.

FIG. 5 shows the fourth embodiment. This example is
The heater (or cooling means) 21 is made of elastic thin metal wire (soft elastic material), and this heater (or cooling means) 21 also serves as a cushion.

Note that the back wall does not necessarily need to be provided.

The air-conditioning air blowing panel according to the present invention is not limited to the above embodiments. In the above embodiment, a single heat exchanger is used for heating means and cooling means, and heating and cooling are performed by changing the heat medium, but heating means and cooling means are separately provided on the upstream side of the air outlet. They may be arranged in parallel nearby.

〔Effect of the invention〕

As seen above, the air-conditioning air blowing panel according to the present invention is provided with an air passage in the panel that communicates with the air inlet formed on one side of the panel, and the air passage is provided on the front wall side of the panel. In an air-conditioning air blowing panel having air outlet ports arranged from the upstream side to the downstream side of the air path, the air outlet panel has air heating and/or cooling air outlets in the vicinity of the upstream side of each air outlet of the air path. Since the means are in place,
Hot or cold air is blown out with no temperature difference from the upstream side to the downstream side, and heat radiation is suppressed from surfaces in contact with the ceiling or walls and surfaces in contact with indoor air, so that the amount of heat is used effectively. It is something that can be done. moreover,
Since heat radiation is suppressed, the temperature response of the blown air at the start of operation becomes faster.
