Description

[0001]
TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to an air conditioning method for conditioning air in a living room and a house in which a living room is air-conditioned by the method.
[0002]
[Prior art]
Generally, an air conditioner is installed in a house in a living room (hereinafter, referred to as a room) such as a living room or a bedroom, which stays for a relatively long time. There is a large window for taking in external light. However, the air conditioner is generally installed on the side wall of the window, on the window, or diagonally above the window.
[0003]
For this reason, general air conditioners are designed so that the air is hardly hit by the user by sending conditioned air in the horizontal direction during the cooling operation or the dehumidifying operation. FIG. 4 is a diagram illustrating a behavior of an airflow sent from the indoor unit 1 in a room 33 in which the general air conditioner is installed at a general installation position. In the case of FIG. 4, the distance between the outlet 5 of the indoor unit 1 and the ceiling S is set to be small. In this case, as shown in the figure, the conditioned air (C) blown out from the outlet 5 in the horizontal direction flows along the ceiling S due to the Coanda effect. .
[0004]
However, when the indoor unit 1 is installed so that the distance between the outlet 5 and the ceiling S is increased, as shown in FIG. 5, the conditioned air blown forward and upward from the outlet 5 immediately after the blowout, A so-called short-circuit airflow (E) flowing into the indoor unit 1 without diffusing into the entire room 33 due to the viscosity, and an airflow (G) descending due to the low temperature and high density and flowing down into the living space of the room 33 occur. .
[0005]
In order to improve the comfort of the living space, for example, as described in Japanese Patent Application No. 2002-029903 filed by the applicant, conditioned air is directly sent to the user by sending conditioned air upward during cooling operation or dehumidifying operation. An air conditioner has been researched and developed which can prevent the wind from hitting, secure comfort and health safety, and can make the temperature distribution and the ion concentration distribution of the entire room 33 uniform.
[0006]
According to the air conditioner described above, the conditioned air is sent and blown upward during the cooling operation and the dehumidifying operation. FIG. 6 is a diagram illustrating the behavior of the airflow sent from the indoor unit 1 at this time. That is, the conditioned air (B) blown forward and upward from the outlet 5 of the indoor unit 1 reaches a ceiling S of the room 33 as a high-speed jet, and a wall surface, a floor surface, and an indoor unit facing the indoor unit 1. It returns to the indoor unit 1 by sequentially traveling along the wall surface on the mounting side. Therefore, the airflow reaches all corners of the room 33, and the airflow greatly agitates the entire room, and the temperature distribution of the entire living area except for a part above the room 33 is uniformed, so that the user does not feel the wind directly. You can get space.
[0007]
According to the air conditioner described above, when the distance between the outlet 5 of the indoor unit 1 and the ceiling S is separated to some extent, the above effects can be obtained. However, when the distance between the outlet 5 and the ceiling S is extremely small, the conditioned air blown forward and upward from the outlet 5 is relatively close to the inlet of the indoor unit 1 as shown in FIG. A so-called short-circuit airflow (E) that collides with the ceiling and flows into the indoor unit 1 without diffusing into the entire room, and an airflow (F) that collides with the ceiling and falls down into the living space of the bouncing room 33 occurs.
[0008]

[0009]
[Problems to be solved by the invention]
During the cooling operation or the dehumidifying operation, the short-circuit airflow (E) not only causes a decrease in the air conditioning efficiency but also lowers the temperature of the air sucked from the suction port. There is a problem that it becomes impossible to grasp accurately. In addition, the air flow (G) that descends due to the low temperature and high density and falls down into the living space of the room 33 and the air flow (F) that collides with the ceiling and falls down into the living space of the room 33 gives discomfort to the user. In addition, there is a problem that the body temperature of the user is locally lowered and health is impaired. Further, although the comfort of the room greatly depends on the blowing direction and the installation position of the air conditioner, a good method for determining the installation position of the air conditioner has not been developed in the past. The present invention has been made in view of the above problems, and an object of the present invention is to provide a method for determining an installation position of an air conditioner that can improve the comfort of a living space. And it aims at provision of the house which installs an air conditioner by the method.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is characterized in that an air conditioner is installed at an upper portion of a side wall of a living room (room), and air is blown obliquely upward from an outlet toward a ceiling wall of the living room to perform air conditioning. According to this configuration, during the cooling operation and the dehumidifying operation, the temperature distribution and the ion concentration distribution of the entire room can be made uniform without directly blowing air to the occupants.
[0011]
Further, assuming that the distance from the outlet to the ceiling wall is b (m) and the angle between the direction in which the conditioned air is blown out and the horizontal is θ (deg), the installation function F (b, θ) = b × b / (2 tan θ) By installing an air conditioner such that the air conditioner satisfies 0.05 ≦ F (b, θ) ≦ 0.7, the airflow that short-circuits and the airflow that falls into the living space of the room slightly occurs, but the temperature distribution of the entire room And the ion concentration distribution can be made uniform.
[0012]
Desirably, if the value of the installation function F (b, θ) is set to 0.15 ≦ F (b, θ) ≦ 0.4, the airflow that is short-circuited and the airflow that falls into the living space of the room are suppressed, More desirably, if the value of the installation function F (b, θ) is set to 0.25 ≦ F (b, θ) ≦ 0.35, the airflow that flows into a short circuit and the airflow that falls into the living space of the room is greatly suppressed. The above effects can be greatly improved. Furthermore, if 0.25 ≦ F (b, θ) ≦ 0.35 and 10 ≦ θ ≦ 35, the airflow that short-circuits and the airflow that falls into the living space of the room can be almost prevented, and the above effects are maximized. Can be obtained.
[0013]
Then, by making the living room air-conditioned by the above-described air-conditioning method, it is possible to sell houses that are called healthy houses, comfortable houses, and the like, and the sales promotion effect is improved.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. For convenience of explanation, the same parts as those in FIGS. 4 to 7 of the conventional example are denoted by the same reference numerals.
[0015]
Here, the definition of the blowing direction of the airflow used in the description of the present specification will be described. Horizontal blowing is performed when the air is discharged from the outlet 5 in parallel to the horizontal plane, upward blowing is performed when the air is discharged at a positive angle upward with respect to the horizontal blowing, and downward blowing is performed with respect to the horizontal blowing. Is sent out at the corner of the lower side is referred to as downward blowing. These directional descriptions are not limited to the indoor unit 1 and may be used.
[0016]
FIG. 1 is a schematic side sectional view showing the air conditioning method of the present invention. An air conditioner indoor unit 1 having a suction port 4 for sucking air-conditioned air at an upper part of the airframe and a blowout port 5 for sending conditioned air diagonally upward at a lower part of the air conditioner indoor unit 1 at a specific installation position on the upper side wall of the room 33. Attached. This indoor unit 1 sends out conditioned air in the direction of the arrow (upper front) in the drawing during the cooling operation or the dehumidifying operation.
[0017]
Now, the distance from the upper end of the outlet 5 of the indoor unit 1 to the ceiling wall S is b (m), the angle between the upward blowing direction of the conditioned air and the horizontal plane is θ (deg), and the installation function F (b , Θ) = b × b / (2 tan θ), the installation function F (b, θ) represents the area of the triangle 34 in the figure. There is a close relationship between the value of the installation function F (b, θ) and the comfort of the room 33.
[0018]
FIG. 2 shows the installation function F (b, θ) when θ = 20 (deg) is fixed in the room 33 of the embodiment of the present invention during the cooling operation or the dehumidifying operation, and the ceiling S with respect to the amount of conditioned air delivered. FIG. 3 is a relationship diagram showing a ratio (%) of an amount of air arriving at the air conditioner and a ratio (%) of a short circuit amount to an amount of conditioned air sent out. FIG. Sometimes θ when the installation function is fixed at F (b, θ) = 0.3, the ratio (%) of the amount of air arriving at the ceiling S to the amount of conditioned air delivered, and the short circuit to the amount of conditioned air delivered It is a relationship diagram which shows the ratio (%) of quantity.
[0019]
Here, the relationship between the ratio (%) of the amount of air arriving at the ceiling S to the amount of conditioned air and the ratio (%) of the amount of short circuit to the amount of conditioned air and the comfort of the room 33 will be described. The conditioned air blown forward and upward from the outlet 5 forms a high-speed jet toward the ceiling S of the room 33, a part of which reaches the ceiling S, and the other flows as shown in FIG. E) or an airflow (G) that descends due to the low temperature and high density and falls into the living space of the room 33. As shown in FIG. 7, the conditioned air that has reached the ceiling S sequentially travels from the ceiling wall to the wall surface facing the indoor unit 1, the floor surface, and the wall surface on the indoor unit 1 installation side, and returns to the indoor unit 1. B), or an air current (E) that causes a short circuit, or an air current (F) that collides with a ceiling wall and bounces down into the living space of the room 33.
[0020]
That is, when the ratio of the amount of air arriving at the ceiling to the amount of conditioned air sent out is large, and the ratio of the short circuit amount to the amount of conditioned air sent out is also large, most of the conditioned air sent from the outlet 5 is short-circuited. The air flow (E) or the air flow (F) that collides with the ceiling wall and rebounds and falls into the living space of the room 33, and the air conditioning efficiency is reduced due to the short circuit. Will cause discomfort.
[0021]
When the ratio of the amount of air arriving at the ceiling to the amount of conditioned air sent out is small and the ratio of the short circuit amount to the amount of conditioned air sent out is large, most of the conditioned air sent from the outlet 5 is short-circuited. The air flow (E) or the air flow (G) that falls due to the low temperature and high density and falls into the living space of the room 33 directly hits the occupant, causing the occupant to feel uncomfortable.
[0022]
Furthermore, when the ratio of the amount of air arriving at the ceiling to the amount of conditioned air delivered is small, and the ratio of the amount of short circuit to the amount of conditioned air delivered is small, most of the conditioned air delivered from the outlet 5 has a low temperature. Due to the large density, the airflow descends and becomes an airflow (G) flowing down into the living space of the room 33, and in this case, the wind is directly hit on the occupant, causing the occupant to feel uncomfortable.
[0023]
When the ratio of the amount of air arriving at the ceiling to the amount of conditioned air sent out is large and the ratio of the short circuit amount to the amount of conditioned air sent out is small, most of the conditioned air sent out from the outlet 5 is airflow (B). The air flow reaches all corners of the room, and the air flow greatly agitates the entire room, making the temperature distribution and ion concentration distribution throughout the living area except for the upper part of the room uniform, and direct wind to the user A comfortable space that is not felt can be obtained.
[0024]
From FIG. 2, if the installation position of the air conditioner is set in the range of 0.05 ≦ F (b, θ) ≦ 0.7, the ratio of the amount of air that reaches the ceiling to the amount of conditioned air delivered is relatively large. In addition, the ratio of the short circuit amount to the conditioned air delivery amount can be made relatively small.
[0025]
Further, if the installation position of the air conditioner is set in the range of 0.15 ≦ F (b, θ) ≦ 0.4, the ratio of the amount of air arriving at the ceiling to the amount of conditioned air sent out is further increased, and , The ratio of the short circuit amount to the transmission amount can be further reduced, and the comfort of the room 33 can be increased.
[0026]
Furthermore, if the installation position of the air conditioner is set in the range of 0.25 ≦ F (b, θ) ≦ 0.35, the ratio of the amount of air arriving at the ceiling to the amount of conditioned air delivered is set to approximately 100%, Since the ratio of the amount of the short circuit to the amount of the conditioned air can be minimized, the comfort of the room 33 can be greatly increased.
[0027]
Further, in FIG. 2, when the value of the installation function F (b, θ) is set to the optimum value 0.3, the blowing angle θ, the ratio of the amount of air arriving at the ceiling to the amount of conditioned air delivered, and the conditioned air FIG. 3 is a relation diagram showing the ratio of the short circuit amount to the delivery amount of the air. When the range of the blowout angle θ is 10 ≦ θ ≦ 35, the ratio of the air flow reaching the ceiling to the delivery amount of the conditioned air is approximately 100. %, The ratio of the short circuit amount to the conditioned air delivery amount can be minimized, so that the comfort of the room 33 can be maximized.
[0028]
In the region of F (b, θ) ≦ 0.2 at the blowing angle θ = 20 (deg) or the region of θ ≧ 35 at the installation function F (b, θ) = 0.3, the conditioned air In order to reduce the ratio of the amount of short circuit to the amount of transmission, the air conditioner may be devised as follows: a wall surface of a protrusion protruding from a front portion of the indoor unit 1; When a flat surface or a curved surface extending rearward from the front end of the guide surface is formed by the wall surface of the groove portion recessed in the air conditioner, a short circuit flow along the front surface of the air conditioner can be prevented.
[0029]
Furthermore, if a guide surface is formed such that the upper wall of the air flow path facing the air outlet is inclined upward as going forward, the air can be easily guided upward by the guide surface. Can be increased from the front to the upper front. The guide surface may be provided so as to protrude from the outlet, or may be provided inside the outlet.
[0030]
The living room was air-conditioned by the above-mentioned air-conditioning method, and the air-conditioning method and its effects were published in the construction instructions and sales promotion brochures of the house. Home sales become possible, and the sales promotion effect is improved.
[0031]
As described above, the embodiment of the air conditioner according to the present invention has been described. However, the present invention is not limited to the above embodiment, and is implemented with appropriate modifications without departing from the spirit of the present invention. .
[0032]
【The invention's effect】
According to the present invention, an air conditioner is installed at the upper part of the side wall of the living room, and the air is blown obliquely upward from the outlet toward the ceiling wall of the living room, so that the air does not directly hit the resident. It is possible to improve comfort and health safety by preventing discomfort. The conditioned air sent from the air conditioner reaches the ceiling of the room, and sequentially travels on the wall surface facing the air conditioner, the floor surface, and the wall surface on the air conditioner side. Therefore, the airflow reaches every corner of the room, and the airflow greatly agitates the entire room, so that the temperature distribution and ion concentration distribution of the entire room can be made uniform.
[0033]
Further, assuming that the distance from the outlet to the ceiling wall is b (m) and the angle between the direction in which the conditioned air is blown out and the horizontal is θ (deg), the installation function F (b, θ) = b × b / (2 tan θ) By installing an air conditioner so that the air conditioner satisfies 0.05 ≦ F (b, θ) ≦ 0.7, an air current (E) for short-circuiting and an air current (G) flowing down to the living space of the room are slightly generated. In addition, the temperature distribution and ion concentration distribution of the whole room can be made uniform to some extent.
[0034]
Preferably, the air conditioner is installed so that the installation function F (b, θ) satisfies 0.15 ≦ F (b, θ) ≦ 0.4, thereby providing short-circuit airflow (E) and room occupancy. The airflow (G) falling into the space is suppressed.
[0035]
Furthermore, if the air conditioner is installed so that the installation function F (b, θ) satisfies 0.25 ≦ F (b, θ) ≦ 0.35, the airflow (E) for short circuit and the living space of the room can be reduced. The downflowing air flow (G) can be greatly suppressed, and the above effects can be greatly improved. By setting 0.25 ≦ F (b, θ) ≦ 0.35 and 10 ≦ θ ≦ 35, it is possible to substantially prevent short-circuit airflow and airflow falling into the living space of the room, and to maximize the above-described effects. Obtainable.
[0036]
Then, by making the living room air-conditioned by the above-described air-conditioning method, it is possible to sell houses that are called healthy houses, comfortable houses, and the like, and the sales promotion effect is improved.
