Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an air conditioning system for a relatively large room in an office of a building or a residence.

[Prior art and its problems]

In such rooms, each room is usually equipped with an air conditioner/heater, but if these rooms are partitioned, the rooms will be divided into rooms with air conditioners and those without, making rooms without air conditioners extremely difficult to live in. Become. Therefore, providing separate heating and cooling equipment would result in extremely high costs.

The purpose of the present invention is to eliminate such inconveniences of the conventional example, and to air-condition both partitioned rooms by simply adding simple equipment without installing new air-conditioning equipment. Our objective is to provide an auxiliary air conditioning system that can be used with partitions.

[Means for solving the problems] In order to achieve the above object, the system of the present invention has the following features:
In the case where a room in which an air conditioner/heater is installed is divided into a room with the air conditioner/heater and a room without the air conditioner,
The main idea is to provide a communication port between the two chambers at the bottom of the partition, and to connect the air vents provided in the ceilings of both chambers with a ventilation duct with a blower that can be rotated forward and backward in the middle.

[Effect]

According to the present invention, it is possible to take in air that has been cooled or heated from an adjacent room that is partitioned by the action of a ventilation duct equipped with an air blower, and even a room that does not have air conditioning equipment can be air-conditioned at low cost.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

Fig. 1 is a vertical cross-sectional side view showing an embodiment of the system of the present invention, and Fig. 2 is a cross-sectional plan view of the same. Shows the air conditioner.

When the room 1 is partitioned with a partition 3 according to the need, it is divided into a room B with the air conditioner 2 and a room A without it.
A communication port 4 between both chambers of B was formed. The communication port 4 may be continuous or discontinuous, regardless of its shape.
It may also be covered with lint or the like.

On the other hand, a ventilation duct 5 is installed in a place where the partition 3 is installed, such as in the ceiling, so as to span over both rooms A and B, and the ends of the ventilation duct 5 are placed on or near the ceilings of rooms A and B, respectively. The duct 5 communicates with the air terminals 6, 6' provided.
6' were interconnected.

In addition, an air blower 7 that can be rotated forward and backward is installed in the middle of the duct 5, and a control panel 8 for this air blower 7 is installed, for example, on the partition 3 or on another wall in room A. Manual operation of instrument 7,
It contains an automatic changeover switch, a rotation speed control switch, a thermostat, etc. The blower 7 receives an output signal from the four-way valve switching point (cooling operation/heating operation switching contact) of the air conditioner/heater 2, and automatically switches on and off. In addition, not only the forward and reverse operation but also the wind force can be varied by the output of the control panel 8.

Next, the usage and operation will be explained based on the flowchart in Figure 3. First, the control panel 8
Operate the manual/automatic selector switch to select automatic or manual operation (step 1). In the case of automatic operation, it differs depending on whether the air conditioner/heater 2 is in heating mode or cooling mode (STEP PRO). In the case of heating operation in winter, the blower 7 is automatically reversed and becomes a "negative" operation (Step 3). As a result, the air in room A is sent to room B by the ventilation duct 5, and
Warm air discharged from the air conditioner/heater 2 of the room flows into room A through the communication port 4 as shown by the solid line arrow in FIG. 1, and warms room A.

In this way, when winter heating is provided, the blower 7
The reason why the duct 5 was not rotated in the normal direction to directly draw in the hot air blown from the air conditioner/heater 2 was to prevent the room temperature in room A from becoming difficult to control. Then, the room temperature in room A is measured with a temperature detector, etc., and it is determined whether it is higher or lower than the set value that is considered to be comfortable for living (step 2), and if it is low, the rotation speed of the fan 7 is increased. More warm air is taken in from room B (Step 5). On the other hand, if the air volume is higher than the set value, the blower 7 further determines whether the air volume is larger than the minimum air volume (step 5). If it is larger, the air blower 7 (step), and if it is equal to the minimum air volume, secure that air volume (step).

When the air conditioner/heater 2 is performing cooling operation in the summer, the blower 7 is rotated in the normal direction to perform "normal" operation (step). As a result, the ventilation duct 5 sucks in the cold air from the air conditioner/heater 2 in room B and sends it to room A, thereby cooling room A (step).

The dotted arrows in FIG. 1 indicate such air flow, in which heated air from room A is sent to room B through the vent 4.

Then, as with heating, it is determined whether the temperature in room A is lower or higher than the set value (step nu),
If it is low, it is assumed that the air conditioner is sufficiently cooled, and it is further determined whether the air volume is larger than the minimum air volume of the blower 7 (Step O). If it is larger, the rotation speed is decreased (Step O), and the minimum air volume is If so, ensure that state (step).

Furthermore, if the room temperature in room A is higher than the set value, the number of revolutions of the blower 7 is increased (stepper), assuming that the cooling is insufficient.

When switching to manual operation in step 1 above, set the blower 7 to the “normal” position on the control panel 8.
“Negative” operation can also be switched manually (step
y), and the rotational speed of the blower 7 is also controlled manually.

〔Effect of the invention〕

As described above, the partition compatible air conditioning auxiliary system of the present invention can use existing air conditioning and heating to air condition isolated rooms by simply adding simple equipment without installing new air conditioning or heating equipment. This makes it possible to improve livability with low equipment costs and running costs.

Claims (1)

[Claims] 1. When a room in which an air conditioner is installed is divided into a room with the air conditioner and a room without the air conditioner using a partition, a communication port between the two rooms is provided at the bottom of the partition, and an air blower that can be rotated forward and backward is installed in the middle. This air conditioning auxiliary system is compatible with partitions, and features a ventilation duct that connects the air terminals installed in the ceilings of both rooms.
