Abstract

PURPOSE:To improve dwelling circumstances at the perimetric zone of a building, by employing such an arrangement that air in a space formed between a window glass and blinds is discharged to the outside of the room by producing current of air directed upward from the lower portion of said space. CONSTITUTION:Room air in a space 1 formed between a window glass 2 and blinds 4 is carried upward as primary air by blowing air from the lower portion of the space 1 by means of a fan 7 and discharged to the outside or circulated into the room via an air conditioner 12 by means of an exhaust fan 10. With such an arrangement, the temperature of air at the permetric zone of a building is controlled at the hollow space 1 between the window glass 2 and blinds 4 to meet with the temperature of air at the interior zone. Thus, since scattering of heat accumulated in the space 1 between the window glass 2 and blinds 4 and occurrence of cold draft can be prevented, the temperature circumstances at the perimetric zone can be improved.

Description

[Detailed Description of the Invention] The present invention relates to an air conditioning method in a building, and in particular,
Indoor air is passed from the bottom to the top through the gap formed by the window glass facing the outdoors and the blind hung indoors on this window glass, and the heat accumulated in the cross-flow heat blind inside the window glass is removed. It is removed in the air gap to harmonize the room temperature in the perimeter zone and the room temperature in the interior zone.

By reducing the temperature of the blind body and reducing the radiant heat from the blind surface toward the indoor side, living in the perimeter zone is made more comfortable. In general buildings,
Inside the room, there is a perimeter zone that is easily affected by outdoor temperature changes, and indoor air conditioning loads (mainly lighting, human bodies, heat generating equipment).
A distinction is made between the interior zone and the affected interior zone.

Therefore, especially the glass window portion of the perimeter sea 7 has a high thermal conductivity and also has a high solar radiation transmittance.
It is difficult and rare to control the indoor temperature in the perimeter zone at a constant level because it fluctuates significantly due to direct outdoor influences. Therefore, conventional air conditioning methods have either controlled the perimeter zone and the interior zone with separate air conditioners, or controlled both zones with a single common air conditioner. However, in the former case, the equipment,
Not only does the cost of the equipment increase, but the two zones interfere with each other, resulting in a mixed loss of heat load and other misalignment. In addition, in the latter case, the heat load characteristics of the two zones are significantly different, making it difficult to create a comfortable temperature environment. In some cases, it may be necessary to cool the interior zone and heat the perimeter zone, but in this case such temperature control is no longer possible.

This invention solves this problem in general buildings. That is, an object of the present invention is to effectively harmonize the temperature between the meter zone and the interior zone, and an object of the invention is to improve the energy saving effect of the air conditioning system by harmonizing the temperature between the perimeter zone and the interior zone. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a method for individually controlling the temperature of the perimeter sea/interior zone.

As shown in the illustrated embodiment, the present invention has a cavity 1 formed by a windowpane 2 facing outdoors and a blind 4 suspended from the indoor side of the windowpane 2 to block solar radiation. Indoor air is sucked as it is from the lower part of the cavity, this indoor air is used as primary air and blown out from the bottom to the top within the cavity 1, and this secondary air is sucked through the suction port 8 provided at the upper part of the cavity 1. By doing so, the heat from the blinds heated by the transmission of solar radiation is removed, and the heat passing through from the glass surface is also removed and discharged to the outside.
2. The present invention relates to an air conditioning method characterized by returning to

This invention sends indoor air from the lower part to the upper part of the gap formed between the window glass and the blind, and guides the air outside at the upper part, thereby controlling the temperature of the perimeter zone between the blind and the window glass. The process is performed in the void formed between the window glass to harmonize the temperature with the interior zone. In other words, it eliminates the solar radiation load and cross-flow heat load that occur between window glass and blinds. As a result, heat accumulated in window glass and blinds does not spread to the surrounding area. Additionally, the temperature environment in the perimeter zone becomes comfortable without being affected by cold drafts from glass windows and blinds that occur during the winter. According to experiments, in the gap formed between the window glass and the blind, the
Since only a small amount of air of H is required, the power for air supply and exhaust is small, which is good, and there is no feeling of airflow in the perimeter zone, making it comfortable. Since the air blown into the gap is indoor air, it is almost equal to room temperature and has little heat loss.

Example: A blower device 5 is attached to the lower part of the gap 1 formed between the window glass 2 and the blind 40 to blow indoor air.

Suction is sucked in from the suction port 6 and then blown out from the old 7. While exchanging heat with the surfaces of the window glass 2 and the blinds 4, it flows into the suction port 8 of the ceiling 6, passes through the exhaust duct 9, and is then discharged into the room by the exhaust fan 10. Air whose temperature has risen (or fallen) above the air temperature is either directly exhausted outdoors or returned to the air conditioner 12 and reused.

The air used here is blown using a part of the return air used for indoor air conditioning, and the air is blown by blower device 5.
The interior consists of only the air filter 11 and a small fan with low static pressure, making the structure extremely simple and compact.

The gap 1 formed between the window glass 2 and the brine 4 is too large, and if it is too large, there will be insufficient heat exchange with the blown air.
(within).

According to this embodiment, it is possible to effectively and economically air-condition the 4 meter zones and interior zones within a building using a single air conditioner by effectively utilizing blinds. The energy saving effect is extremely remarkable.
