Abstract

PROBLEM TO BE SOLVED: To place outdoor supply air, heat exchanged with exhaust air, in the proximity of a canopy in winter season and place supply air, without exchanging heat, in the proximity of the canopy in summer and intermediate seasons. SOLUTION: In winter season, inner tubes 9 and outer tubes 10 of a heat exchanging chamber 8 are disposed in a heat exchanger air supply/exhaust canopy 1. In summer and intermediate seasons, upper vent of a ventilation chamber and lower vent 23 of a heat insulating tube are disposed in the heat exchanger air supply/exhaust canopy 1. Consequently, the heat exchanger air supply/exhaust canopy realizes a warm work environment in winter season and a cool work environment in summer and intermediate seasons.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchanger supply / exhaust canopy.

[0002]

2. Description of the Related Art In a method in which a canopy for directly taking in outside air and supplying air to an exhaust canopy is superposed on the outside, an air curtain is formed by taking in air supply from around the outside of the exhaust canopy, and combustion is performed. In addition to preventing hot air and combustion gas emitted from the appliance from diffusing into the room, the supply air attracts hot air and combustion gas and exhausts the air efficiently.

[0003]

However, during the winter period, since outside air is directly taken in and supplied with air, a person who works around the air supply / exhaust canopy is exposed to cold air and may not be used. is there.

[0004]

Means for Solving the Problems A supply / exhaust canopy has a heat exchanger which attracts hot air, combustion gas, etc., efficiently exhausts the exhaust air, and uses the waste heat to heat the air supply. By having a configuration of a heat exchanger supply and exhaust canopy characterized by that
Warm air supply is introduced during winter. Further, in the summer and the intermediate period, the ventilation equipment which does not exchange heat can be exchanged, and it is possible to take in air supply suitable for each season, thereby solving the above-mentioned problem.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a heat exchanger air supply / exhaust canopy used in winter uses hot exhaust gas or combustion gas emitted from a combustion apparatus (26) by operating an exhaust fan (2).
Then, through the exhaust port (12), the space in the gap between the outside of the inner tube (9) and the inside of the outer tube (10) of the heat exchange chamber (8) receives radiation and takes on hot air.

[0006] When cold air from the outside passes therethrough, the heat of the exhaust of the inner pipe (9) heats the cold air. At this time, heat exchange between supply air heat and exhaust heat is performed, the exhaust gas is deprived of heat, and is sucked by the exhaust fan (2) from the exhaust chamber (6) and discharged outside.

The air supply is taken in from the outside together with the operation of the air supply fan (3), and from the upper air supply chamber (7),
Heat is passed through the gap space between the outside of the inner pipe (9) of the heat exchange chamber (8) and the inside of the outer pipe (10) by heat exchange, and passes through the lower air supply chamber (11) to supply air (14). ) And evenly out of the air inlet (15) to form an air curtain,
Attracts exhaust air for efficient ventilation.

As shown in FIG. 2, the heat exchanger air supply / exhaust canopy used in the summer and the interim period emits hot air and combustion gas emitted from a combustion apparatus (26) by operating an exhaust fan (2). And passed through the exhaust port (12),
After passing through the heat insulating pipe (18) of the ventilation chamber (17), the air is sucked by the exhaust fan (2) from the exhaust chamber (6) and discharged outside. The heat insulating pipe (18) is obtained by covering an oval pipe with a heat insulating material.

The air supply is taken in from the outside with the operation of the air supply fan (3), passes through the upper air supply chamber (7), from the upper air vent (22) to the air chamber (17), and then to the lower air vent (17). 23), it passes through the air supply guide (14) and evenly exits from the air supply port (15) to form an air curtain, attracts exhaust air, and performs efficient ventilation.

When the heat exchanger supply / exhaust canopy is of the winter type, the inner pipe (9), the outer pipe (10), the exhaust chamber partition (19), the upper supply chamber partition (20), the lower supply. The heat exchanger composed of the air chamber partition plate (21), the exhaust canopy (16), and the air supply guide spacer (24) is placed directly below the heat exchanger air supply and exhaust canopy body (1) and the air supply canopy (13). Insert the connection screw (2) from outside the air supply canopy (13).
In 5), the lower air supply chamber partition plate (21) and the air supply guide spacer (24) are screwed and fixed respectively.

When the supply / exhaust canopy of the heat exchanger is to be used in the summer and the middle season, a heat insulating pipe (18), an exhaust chamber partition (19), an upper supply chamber partition (20), and a lower supply chamber partition. A ventilator consisting of a plate (21), an exhaust canopy (16), an air supply guide spacer (24), etc.
Insert the heat exchanger from below the air supply and exhaust canopy body (1) and air supply canopy (13), and connect the lower air supply chamber partition plate (21) with connection screws (25) from outside the air supply canopy (13). Each is screwed and fixed to the air conducting spacer (24).

[0012]

The heat exchanger air supply / exhaust canopy according to the present invention is equipped with a heat exchanger during use during the winter season, thereby reducing the heat of exhaust gas such as hot air and combustion gas emitted from a combustion appliance.
Heat the cold air taken in from outside by heat exchange,
Form an air curtain of warm air between the canopy and the workplace. In addition, in summer and in the middle, air taken in from outside without supplying heat through heat insulation pipes also forms an air curtain of cool air between the canopy and the workplace.
This provides a heat exchanger air supply and exhaust canopy that provides a warm and comfortable working environment during the winter months and a cool and comfortable working environment during the summer and mid-season.
