Abstract

PURPOSE:To obtain comfortable air-conditioning over the whole of an indoor room by avoiding sending air directly against a human body, in the time of normal air- conditioning, by a method wherein by air-flow-shifting louvers, the main direction of air-flow is set facing the wall surfaces, right and left, which adjoin the wall surface forming an air-supplying opening. CONSTITUTION:Immediately after a person enters a room or when air-conditioning operation begins to be started, the air through a supply opening l is directly sent against a human body 4, and after a definite time elapses, the air is suitably sent against walls like arrow marks, each of which is shown with a solid line, in order to avoid being directly sent against the human body 4. As the result of it, at the time of normal air-conditioning, the temperature of the side walls and interior equipment in a room can be approached to a preset value, and a comfortable space can be spread over the whole of the room, in using radiation like arrow marks, each of which is shown with a broken line. When air-conditioning operation begins to be started, or at the time of cooling immediately after the person enters the room, air-flow-shifting louvers 3 are variably controlled one by one so that the direction of air-flow blown directly faces the human body, while being operated together with indoor conditions estimated and detected by a timer or a human body-detecting sensor, and such is also effective for the comfortable space.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a duct air conditioner for heating and cooling, in which an air outlet is provided on an indoor wall surface or the like.

2. Description of the Related Art Conventionally, a duct air conditioner is installed on a wall with its blowing surface facing indoors, as shown in Fig. 3. The air was sent out from the blow-off surface 5 installed at the same time. In this duct air conditioner, air conveyed from the duct is sent out over the entire blowout surface in a direction perpendicular to the blowout surface.

Problems to be Solved by the Invention However, in such a duct air conditioner, if the entire air outlet is directed directly into the living area, there will be a large temperature difference and wind speed difference with the surrounding atmosphere.
0 and changes in wind speed are extremely uncomfortable. In addition, direct exposure to the jet stream had negative effects on human health. Furthermore, since there is no air blowing in the direction of the wall surface, there is a small change in the temperature of the wall surface, making it difficult to condition the air by radiation from the wall surface, making it difficult to obtain sufficient comfort. In addition, even when air is blown horizontally from the blowing surface to avoid the human body,
Because of the relatively wide distribution of room temperature and wall temperature, it has been difficult to achieve uniform comfort.

As described above, conventional duct air conditioners still have room for improvement and were not optimal.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a duct air conditioner that can perform comfortable air conditioning.

Means for Solving the Problems The present invention provides a wind direction control blade row at the outlet for blowing air at a predetermined temperature and flow rate, and directs the main direction of the air to the left and right wall surfaces adjacent to the wall surface forming the outlet. can be set to the left and right sides, respectively.

In addition, in the case where a wind direction control blade row is installed at the outlet that blows air at a predetermined temperature and flow rate, the air is blown directly to the human body during startup operation of the air conditioner, and the air is blown directly to the human body during steady operation, and when the air conditioner is in steady operation, the air is blown directly to the wall surface on which the outlet is formed. The present invention is characterized by the provision of a control device that operates a wind direction control blade row so as to blow air along the left and right wall surfaces.

The wind direction can be controlled by the wind direction control blade array attached to the working air outlet, making it very easy to blow air toward the left and right walls of the living space. In addition, by controlling the wind direction control blade array, air is blown directly to the human body during startup operation of the air conditioner, and air is blown along the wall during steady operation, so that the temperature of the wall reaches the set value and becomes even more uniform. I can do it. As a result, comfortable air conditioning that fully utilizes wall radiation can be achieved.

Embodiment Next, an embodiment of the present invention will be described based on the accompanying drawings. FIG. 1 shows a duct air conditioner according to an embodiment of the present invention, in which air at a predetermined temperature and flow rate is conveyed through a duct 2 at an outlet 1 outside the wall and blown into the room. 3
is a wind direction control blade row for controlling the direction of the blown air.

The specific effects and operations of the above-mentioned embodiment with such a configuration are as follows.
This will be explained based on FIG. Generally, when heating, hot air directed directly at the body often causes discomfort. On the other hand, when it comes to cooling, strong cold air is often comfortable when starting air conditioning or immediately after entering a room, but during constant cooling or when sleeping, direct cold air not only causes discomfort to the human body but also has an adverse effect on health. Furthermore, it is extremely difficult to provide sufficient comfort throughout the entire indoor living space by air conditioning only by adjusting the temperature of the indoor air flow Φ.

Therefore, as shown in Figure (a), immediately after entering the room, when the air conditioner starts operating, the human body. After a certain period of time, (b) As shown in the figure, the air from the air outlet 1 should be directed toward the wall as shown by the solid arrow, avoiding direct air blowing to the human body. As a result, the temperature of the side walls and interior of the room can be brought closer to the set price,
As shown by the dashed arrow, radiation is used to spread a comfortable space throughout the room.

Here, as mentioned above, when air conditioning is started or when cooling immediately after entering a room, the wind direction control blade row 3 is adjusted temporally or by a human body sensor so that the blowing direction is directed directly toward the human body.
It is also effective to perform variable control sequentially while linking to the sensed indoor situation. Then, during steady heating operation, the main direction of air is set by the wind direction control blade row to the lower left side and lower right side, while during cooling operation, air conditioning is started by setting the main direction of air to the upper left side and upper right side. It is possible to maintain a very comfortable space continuously from time to time.

Effects of the Invention According to the present invention, the wind direction is controlled differently during start-up operation and during steady air conditioning, and during steady air conditioning, direct air blowing to the human body is avoided, and radiation from the side walls by blowing to the left and right is used. , it is possible to realize a comfortable space throughout the room.
