Description

[Detailed Description of the Invention] This invention utilizes opening/closing bodies such as rooms (chambers) and doors in buildings as ventilation channels and air volume adjustment devices for guiding intake and exhaust during air conditioning, without using ducts or dampers. This invention relates to an air conditioning intake and exhaust device.

Air conditioning can be used either for cooling or heating, or for ventilation without heating or cooling.
The latter is called the intermediate period, and in this case, while the former reuses a portion of the return air after heating and cooling as part of the air conditioner's intake air, all of the intake air is introduced from outside air, and all return air is outside air. Release inside.

In recent years, there has been a demand for energy conservation in air conditioning as well, and there is a trend to shorten the heating and cooling period, and naturally the above-mentioned operation pattern with a long intermediate period is often adopted. Therefore, an air conditioning system that meets this requirement is desired.

By the way, in conventional air conditioning systems, intake and exhaust of outside air are all performed using duct piping. This is because the electric damper has the advantage that the outside air introduction ratio can be easily adjusted during cooling and heating. This method can automatically and quickly adjust the outside air introduction ratio and control the room temperature, unlike conventional air conditioning systems that require long heating and cooling periods. However, in air conditioning for general buildings where intermediate temperature control is not required, it is sufficient to manually adjust the outside air introduction ratio at most. Therefore, conventional duct-based systems that require a duct junction box or an electric damper, which requires space comparable to the air conditioner itself, are expensive and space-consuming, making them unsuitable for modern systems with long interim periods.

This invention was made in consideration of the above points, and by using the rooms of buildings themselves as ducts and making opening/closing bodies such as doors function as dampers, it is possible to simplify the equipment without using ducts or dampers. The purpose of the present invention is to provide an air conditioning intake/exhaust device that can reduce the space of the entire air conditioning equipment and reduce construction costs, and is compatible with the current situation with a long interim period.

Hereinafter, the content of this invention will be explained with reference to the drawings.

Figures 1 and 2 show an embodiment of the present invention. In the figure, 1 is an air conditioner room installed in one section of a building, and the wall has an air intake port 2 for sucking outside air. It is provided. And this air conditioner room 1
An air conditioner 3 is installed inside. The air inlet side of the air conditioner 3 is located toward the intake port 2 and is open so that air can be freely sucked from the intake port 2, and the outlet side of the air conditioner 3 is located in the air conditioner room. An air supply duct 4 for supplying air to a room to be air-conditioned outside the room is connected.

Next to the air conditioner room 1, there is a return chamber 5.
is provided. This is a room that collects the return air after conditioning the room to be air-conditioned; one side has a return air intake port 6 for taking in the return air, and the other side has a return air intake port 6 for discharging the taken in return air into the outside air. An exhaust port 7 is provided respectively. In addition, including the above-mentioned intake port 2,
The return air intake port 6 and the exhaust port 7 are all equipped with louvers. Furthermore, an exhaust fan 8 (pressure fan with automatic shutter) is provided inside the exhaust port 7. A door 9 is provided on the wall separating the two adjacent rooms, that is, the air conditioner room 1 and the return chamber 5, to connect the two rooms.

Next, a case will be described in which air conditioning is actually performed using the apparatus having the above configuration. First, in the intermediate period, only ventilation is required, and as shown in FIG. 1, the door 9 is closed, the exhaust fan 8 is operated, and all return air is exhausted from the exhaust port 7 into the outside air. Therefore, fresh air enters from the intake port 2 as the air is exhausted, and fresh air is introduced to the air supply duct 4 to perform ventilation without operating the air conditioner 3. In this case, if a plurality of exhaust fans 8 are provided, the exhaust amount can be adjusted in stages.

Next, during heating and cooling, as shown in FIG. 2, the door 9 is manually opened so that a portion of the return air flows into the air conditioner room 1 side. As a result, a portion of the return air is sucked into the air conditioner 3 along with the outside air from the intake port 2. Here, by appropriately setting the opening degree of the door 9 and the opening degree of the intake port 2, the outside air introduction ratio can be manually adjusted very easily. In this way, the space of the room itself functions as a duct, and the door 9 functions as a damper for adjusting the air volume, so although it is not possible to make quick fine adjustments to the air volume as with the duct damper method, it is possible to adjust the air volume in the intermediate period. It is possible to sufficiently cope with the air conditioning of recent general buildings, which have a long period of time.

Note that the door 9 is a normal door or door that is large enough for a person to pass through, and it is desirable that the installation location or opening direction be determined depending on the ventilation condition. Further, a window may be used instead of the door 9.

As explained above, according to the present invention, air intake and exhaust processing for air conditioning can be performed with simple equipment using opening/closing bodies such as rooms of buildings or doors, without using ducts or dampers. As such, it does not require space for duct connection boxes, etc., reducing the overall space of the air conditioning equipment, significantly reducing construction costs, and being extremely easy to apply to existing rooms. have an effect.
