Abstract

PURPOSE:To enable comfortable airconditioning which allows a man on a bed to sleep sound by providing a blowoff pot and a suction port on a ceiling so that the air velocity on the upper surface of a bed may be specified value or below and a predicted mean vote may satisfy the specified values. CONSTITUTION:A blowoff port 3 and a suction port 4 are provided on the ceiling 2. The blowoff port which is open to the surface of the ceiling 2, is provided in a blowoff box 5 while the suction port 4, which is open to the surface of the ceiling 2, is provided in a suction box 6. Both the blowoff box 5 and the suction box 6 are communicated with an airconditioner 8 by way of a duct-shaped ventilation passage 7. The air in a room 9 is absorbed from the suction port 4 by the drive of the airconditioner 8 so as to perform airconditioning. The airconditioning air is adapted to be discharged from the blowoff port 3 into the room 9. A bed 1 is arranged in the room 9. The blowoff port 3 and the suction port are installed so that the air velocity on the upper surface of the bed 1 may be 0.2m/sec or below and PMV(predicted mean vote) may satisfy the specified value within +1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a system for air conditioning a domestic bedroom.

[Prior Art] Currently, most air conditioning (especially cooling) in living rooms in homes is carried out by air conditioners hung on the wall, and wall-mounted air conditioners are the mainstream.

[Problems to be Solved by the Invention] However, in wall-mounted air conditioners, there are considerable variations in indoor temperature distribution, airflow distribution, etc., and people may feel uncomfortable due to the thermal environment.

Moreover, since conventional air conditioning systems only cool or heat the room, they cannot necessarily be said to be comfortable air conditioning systems that do not interfere with sleep for people sleeping in bed.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a bedroom air conditioning system that can perform air conditioning so that a person who sleeps on a bed can have a comfortable sleep. There is something to do.

[Means for Solving the Problems] In order to achieve the above object, the bedroom air conditioning system of the present invention is designed so that the wind speed above the bed 1 is 0.2111/see or less and the PMV (predicted mean declared value) is within ±1. (A blowout port 3 and a suction port 4 are provided on the ceiling 2.

[Function] The room is air-conditioned by blowing air into the room from the air outlet 3 provided on the ceiling 2 and sucking the indoor air through the air inlet 4. In this case, the wind speed at the top of the bed 1 is 0.2 m/min. See or less and PMV (predicted average declared value)
By making sure that the value is within ±1, the person sleeping on bed 1 will be in the most comfortable condition. I can now sleep.

[Embodiment 1] A ceiling 2 is provided with an air outlet 3 and an inlet 4. That is, in the embodiment shown in the attached drawings, the back I of the ceiling 2
II (upper surface 1ll) is provided with a blowout box 5 and a suction box 6. The blowout box 5 is provided with a blowout port 3 that opens to the surface (lower surface side) of the ceiling 2, and the suction box 6 is provided with a blowout port 3 that opens to the surface of the ceiling 2 (lower surface side). A suction port 4 that opens on the (lower surface I) is provided. The air outlet box 5 and the suction box 6 are connected to air conditioners 8 and 8 through various ventilation passages 7 of ducts, and when the air conditioners 11' and 18 are operated, air from the room 9 is sucked through the suction port 4 and air-conditioned. The conditioned air is blown out from the outlet 3 to the FFR1 house 9. In the embodiment shown in FIG.
Although the example in which the spacer 8 is disposed on the back side of the ceiling 2 is shown, the sky 1111 mB may be disposed in a part other than the ceiling. Note that the air conditioner 8 may be attached to the ceiling material that constitutes the ceiling 2 in advance.

A bed 1 is arranged in the room 9, and a bathtub opening 3 is installed in the ceiling 2 so that the wind speed is 0.2a+/see or less above the bed 1 and the PMV (predicted mean declared value) is within ±1. A suction port 4 is provided.

Here, P M V (P directed Mea
n V ote) is called the predicted average declared value or predicted average thermal sensation, and is the thermal sensation of the thermal environment.
A reporting scale is adopted in which numerical values 1 to 7 of the HRAE 7-level evaluation scale are set to -3 to +3, and it is expressed as an index corresponding to the numerical scale.

That is, L=M-W-E-C-R-A M: Quantity W: Work efficiency Kcal/m'h E: Amount of heat dissipation due to moisture evaporation from the skin surface C: Amount of heat dissipation due to convection R: Heat radiation Amount of unused heat due to A: Amount of unused heat due to respiration PMV = lO, 352exp (-0,042 MADU)
+0.32) IXL.

The evaluation scale for hot and cold declarations is as follows.

+3: hot +2: warm +1: lightly warm
0:neuLral -1:slightly cool2
:cool (cool) -3:cold (cold) However, in the present invention, the wind speed is set to 0.2 m/sea or less because the wind speed is 0.2 m/sec on the top surface of the bed 1.
If the wind speed is higher than that, the person sleeping in bed 1 will be unable to fall asleep and will not be able to sleep comfortably. Since it is difficult to sleep, the speed should be kept below 0.2 m/see. And it is desirably 0.1 ea/see or less. In other words, by setting the wind speed to 0.2+s/see or less, the person sleeping on bed 1 will not be bothered by the sound of the wind, will not be bothered by the wind hitting their skin, and will not be disturbed by falling asleep or sleeping.

In addition, PMV (predicted average declared value) on the top surface of bed 1
The reason for this is that it satisfies within ±1.As is clear from the above evaluation scale for thermal and cold declaration, if it is +2 or more and -2 or less, it is comfortable to fall asleep and Vj! This is because although it is difficult to sleep, if it is within ±1, it is possible to fall asleep and sleep comfortably.

In addition, when providing the air outlet 3 and the air inlet 4 on the ceiling 2, the air outlet 3 and the air inlet 4 are not limited to those shown in the embodiment shown in the attached drawings. and suction port 4. Of course, it may be other than this, but in any case, the air outlet 3 is set so that the wind speed is 0.2 m/see or less on the top surface of the bed 1 and the PMV (predicted mean declared value) is within ±1. It is also necessary to provide a suction port 4 on the ceiling 2.

[Effect of the invention 1 As described above, the present invention has a wind speed of 0°2 at the top of the bed.
sec or less and the PMV (predicted average declared value) is within ±1 because the air outlet and inlet are installed in the ceiling, making it the most comfortable for people sleeping on the bed in the room. It has air conditioning that allows you to fall asleep and sleep comfortably.
