Abstract

PURPOSE:To prevent noise from generating without extremely increasing the number of revolutions, and make it possible to perform a comfortable air-conditioning by a method wherein two blowers are provided when blow-out air volume is controlled in response to indoor load. CONSTITUTION:In the vicinity of a left side blow-out port 7, right side blow-out port 8, and a blow-out port for human body 17, a blower for left side load 12, blower for right side load 13 and blower for human body 18 are respectively provided. At respective blow-out ports, air direction controllable air direction control blade rows 14, 15, 19 are provided. At the time of rising-up for air-conditioning operation, or direct blowing to a human body right after entering the room, the temperature, location or activity quantity of the human body are sensed by a sensor for human body 20, an estimated air velocity by amenity index such as PMV, etc., is realized. For blowing from a device main body 1, direct blowing to a human body is appropriately avoided, and air blowing is faced to the wall by the left side and right side blowing airblowers 12, 13 and air direction control blade rows for left side and right side 14, 15. As the result, temperatures of the side wall or interior of the room can be made closer to a set value, and amenity space can be expanded to the whole of the room by utilizing radiation.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to an air conditioner, particularly for heating and cooling.It also relates to an air conditioner installed on an indoor wall, etc. Conventional technology.As an air conditioner installed on an indoor wall, e.g. As shown in Figure 3, indoor air is sucked in from the front of the air conditioner body, and heat-exchanged air is sent out from the bottom of the body.In this air conditioner, only one blower is installed. Most of the adjustments to airflow and air flow are controlled by changes in the rotational speed of the blower.9 Problems to be Solved by the InventionHowever, in such conventional air conditioners,
When increasing the amount of air blown, ζ Even if the rotational speed of the blower is increased as much as possible to obtain the desired amount of airflow, increasing the rotational speed has the disadvantage of generating noise.Of course, if the diameter of the blower is increased, Sumo wrestlers can increase air flow without increasing rotation speed The air conditioner becomes thicker. In addition, since the heat-exchanged air is blown out from below the main body of the air conditioner, the air flow directly hits the human body, which may have negative effects on comfort or health. In many cases, an excessive amount of air blows locally to the human body in the living area, and good comfort is not maintained. As described above, conventional air conditioners had drawbacks such as difficulty in air conditioning due to radiation from the air and insufficient comfort.However, there is still room for improvement in conventional air conditioners, and blowout control is not optimal. The object of the present invention is to solve such problems and to provide an air conditioner that can provide comfortable air conditioning. The air conditioner has a heat exchanger, and an air passage that communicates with a discharge port of the heat exchanger and has a left side outlet, a right side outlet, and a human body outlet on the left side, right side, and bottom of the heat exchanger, and the air passage has a left side outlet, a right side outlet, and a human body outlet. In the passage, the left side air outlet, the right side air outlet, and the human body air outlet are installed, respectively. The air conditioner of the present invention is equipped with a left wind direction control blade, a right wind direction control blade, and a wind direction control blade row for the human body, each of which can control the wind direction individually. Time to control the blowout air volume Power to change the rotation speed of the left and right side load blowers (there are two blowers, so
A sufficient amount of air can be easily obtained without extremely increasing the rotation speed or increasing the diameter of the blower.In addition, the left and right air outlets are located on the left and right sides of the air conditioner body. In addition, the wind direction can be controlled arbitrarily by the left and right side wind direction control blade rows attached to the left and right side air outlets, making it very easy to blow air toward the left and right walls of the living space. It is also possible to control the amount of air blown to the human body separately from the indoor load by using a blower for the human body. Fig. 1(a) is a diagram of an air conditioner according to an embodiment of the present invention, and Fig. 1(b) is a horizontal cross-sectional view near the center of Fig. 1(a). is a longitudinal sectional view near the center perpendicular to the suction surface of FIG. , the heat exchanger 2 has a tube 4 that allows steam or refrigerant to flow between the heat exchanger 2 and the rear casing 5 from around the center of the outlet 6 of the heat exchanger 2 to the left and right and downward. Set up (
The heat exchanger 2 forms an air passage 9 leading from the left side blow-off lower to the right side blow-off port 8.
A filter 11 is attached to the suction port 10 at a position facing the side opposite to the side where the discharge port 6 is provided.A left side load blower 12 installed in the air passage 9,
The indoor air is passed through the filter 1 by the right side load blower 13.
1, the air passes through the suction port 10, reaches a predetermined temperature by the heat exchanger 2, and is blown into the room again through the left and right air passages 9 through the left blowout lower and the right blowout port 9 &14
, 15 are the left side wind direction control blade row and the right side wind direction control blade row for controlling the direction of the blown air, respectively. Even though it communicates with the air outlet 17, the air blower 18 for the human body is provided in the air passage 9 near the air outlet 17 for the human body. The provided human body sensor can sense the warm air, position, or activity level of the human body and control the human body blower 18 and the human body wind direction control blade row 19. The effect will be explained based on Figure 2. First, in Figure 1,
Since the device body 1 is equipped with two blowers, there is no need to increase the rotation speed of the blowers when increasing the air volume.1. %
In other words, if the required air volume is the same, C'L
Compared to the case where only one blower is used, the rotation speed can be reduced, and noise can also be reduced.Furthermore, the diameter of the blower can be made smaller.
Muji 4Q that can be configured thinly as shown in (C)
In FIG. 2, as shown in FIG.
Alternatively, by sensing the amount of activity and controlling the human body blower 18 and the human body wind direction control blade row 19 so as to achieve a wind speed that can be predicted from the comfort index such as L PMV, considerable comfort can be achieved in transient conditions. Even if it is possible to guarantee the same, as before, during high output during start-up operation, the discomfort caused by blowing air directly towards the human body.
Although it is possible to achieve comfortable air conditioning using radiation from walls, as shown in figure (b), the warm air directed directly at the body during heating is There are many cases in which people complain of considerable discomfort.As for cooling, strong cold air is often comfortable at the air conditioning start line or immediately after entering the room (constant cooling line or direct cold air at times such as sleeping is harmful to the human body). It is extremely difficult to provide sufficient comfort throughout the entire indoor living space with air conditioning that only controls indoor air flow and temperature. b) As shown in the figure +Q, the air from the main body 1 of the device is appropriately avoided from being blown directly to the human body, as shown by the solid line arrows, by the left and right side load blowers 12 and 13 and the left and right side wind direction control blade rows 14 and 15. By directing it toward the wall, the temperature of the side walls and interior of the room can be brought close to the set value, and by using radiation as shown by the dashed arrow, it is possible to spread a comfortable space throughout the room, allowing the room to be cooled at the same time. Under the temperature setting that is a little high even when
The human body blower 18 and the human body wind direction control blade row 19 can blow an appropriate amount of air estimated from the indoor temperature/humidity sensor 16 and the human body sensor 20 to the human body, thereby increasing the comfort index such as K PMV. It is also possible to maintain the same value, thereby providing an energy-saving air conditioner.
(The heat exchanger 2 is connected to the human body outlet 17)
By having a configuration that allows the air from the direct suction port 10 to be mixed in an appropriate amount, the human body blower 18
It is also possible to control the temperature of the air blown from the wall, thereby maintaining even better comfort for the human body. Even if the air conditioner of the present invention is installed in a corner of the room, the same effect can be obtained. However, the diameter of the blower can be made smaller, so the air conditioner itself can be made thinner. By using human body sensors to control the air within a range that maintains comfort, by controlling the airflow from the left and right sides according to the load in the room, and by also using radiation from the side walls, it is possible to create a comfortable space throughout the room.
