Description

[Detailed description of the invention] This invention is an air supply/exhaust device for an air conditioner that attempts to introduce and exhaust outside air by using a window frame without drilling a hole in a part of the wall. Regarding.

Conventionally, most air conditioners such as fan coil units have an outside air inlet C as an outside air intake on a wall B where the airframe A is installed, as shown in Figure 1. It had the disadvantage that it had deteriorated significantly and that it was extremely difficult to drill holes in the concrete wall.

In view of these drawbacks, the present invention utilizes a window frame (sash) as an outside air intake and exhaust port without making any openings in the wall, and extremely easily connects the outside air intake and exhaust passages to the air conditioner. The purpose of this system is to provide a high-quality air conditioner with high efficiency.A blower 2 is installed at the lower bottom of the fuselage 1, and a partition plate 3 is provided above the blower 2 to air the air. In an air conditioner in which a passage 4 and an intake passage 5 are respectively formed, and a heat exchange coil D is arranged in the exhaust passage 4, the exhaust passage 4 and the intake passage 5 are connected to a window frame 6 through an air guide pipe 9.
It is characterized in that it is connected to the ventilation passage 7 in a freely connectable manner.

Hereinafter, detailed description will be given with reference to drawings illustrating embodiments of the present invention. 1. A blower 2 is installed in the lower part of the inside of the fuselage, and the air passage in the upper part is divided into front and rear parts by a partition plate 3, and one side is exhausted. A U-shaped ventilation passage is formed in the passage 4 with the other being an intake passage 5, and a heat exchange coil D, a drain pan 10, a humidifier 10', etc. are arranged in the exhaust passage 4, and air is blown toward the upper front side of the fuselage 1. An outlet 11 is installed and opened.

Further, a gas mixing chamber 12 is provided on the suction side, that is, in the upper part of the intake passage 5, and various mechanisms such as a prefilter 13, a filter 14, and a heat pipe 15 for recovering heat from indoor air are disposed inside the chamber. It consists of a gas mixing chamber 12 and an air guide pipe 9 connected thereto.

Reference numeral 16 indicates an openable/closeable suction port which is installed on the upper part of the fuselage 1 and opens toward the indoor side. Reference numeral 17 is an outside air volume adjustment damper with a modular troll motor, and an exhaust damper 18 with a modular troll motor is attached to the exhaust passage 4. The damper opening degree is automatically adjusted by a signal from a thermometer or a CO ₂ sensor, etc., and the former damper 17 automatically supplies the required amount of outside air, and the latter damper 18 is configured to automatically exhaust indoor air commensurate with the intake outside air amount.

Note that the reference numeral 19 in the drawing indicates a cold and hot water pipe.

The window frame 6, that is, the sash frame, is either integrally molded with a suitable molding material, or has a structure in which they are fitted from both sides to form an integral structure, and the inner cavity of the window frame 6 is utilized. A ventilation passage 7 is formed around the entire circumference of the frame or a part of the window frame 6, and appropriate outside air intake and exhaust holes 8 are formed in the window frame 6.

In some cases, it is also possible to attach a partition plate 6' in the ventilation passage 7 so that the position can be freely selected, and to arbitrarily change and determine the outside air intake and exhaust direction, location, area, etc. .

The present invention has the above-mentioned structure, in which the airframe 1 is attached to the wall B, and the air guide pipe 19 is connected to the ventilation passage 7 of the window frame 6, so that outside air is introduced through the intake hole 8. As shown in A, indoor air can be introduced into the aircraft body 1 along with indoor air, and by opening the exhaust damper 18, indoor air commensurate with the amount of outside air taken in can be automatically distributed to the ventilation passage 7 as shown in arrow A. It can be easily discharged to the outside through the exhaust hole 8.

Note that the outside air can be taken in from the upper part of the window frame 6 by operating the partition plate 6', and exhaust can be exhausted from the upper part if necessary, or natural exhaust can be performed using indoor pressure.

(Reference: According to the Building Standards Act, the exhaust hole position must be within 80 cm from the ceiling surface.) As described above, the air supply/exhaust device in the air conditioner according to the present invention utilizes the window frame 6 for exhaust ventilation. 7, there is no need to provide a large-diameter intake hole on the wall B to the hair head for introducing outside air as in the past, and there is no need to worry about spoiling the wall design. In addition to this, it is possible to easily convert the outside air intake passage into an exhaust passage by operating a damper, and it is ideal for the energy saving era, as it does not require any equipment such as air supply or exhaust, or ductwork at all. This is an idea.
