[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner to which an air supply duct is connected, and conditioned air is blown out from air outlets provided at the ends of sub-ducts branched from the air supply duct to face the living room, while the inside of the building The present invention relates to an air conditioning system for air conditioning the entire building by providing a collective intake port at a predetermined position and returning the air sucked from the air intake port to the air conditioner through a return passage.

[0002]

2. Description of the Related Art In recent years, a centralized air conditioner called a so-called multi-system, in which one outdoor unit is shared by many indoor units, has become widespread. This is one that individually heats and cools each room by flowing a heating medium set to a predetermined temperature condition through piping from one outdoor unit to an indoor unit installed in each room of the building. is there.

However, such central heating basically carries out heat exchange through a heat medium, merely performs heating and cooling, and does not ventilate the room at all, and therefore air pollution in the room. Inconveniences such as condensation and dew condensation cannot be avoided. In addition, it is necessary to secure a space to install the indoor unit in each room, and avoid complicated work when installing these and installing refrigerant pipes that connect the indoor unit and the outdoor unit. I can't
The reality is that you have to leave it to a skilled professional.

Therefore, the present applicant previously proposed an integrated centralized air-conditioning system which enables simple on-site piping construction and centralized air-conditioning including cooling and heating and ventilation (Japanese Patent Application No. 1-10).
No. 9999).

This integrated centralized air conditioning system
It is a part of the floor panel, and it air-conditions each room via a branch-shaped air supply duct that leads to each room. It faces the opening and serves as an outlet. Further, in the building, for example, an exhaust duct that opens on the first-floor floor panel of the staircase and opens facing the interior of the building is provided under the floor, and the opening is an exhaust port for exhausting the air in the entire building. Has been done. Therefore, the air supplied from the air supply port to the room passes through the louvers and the clearances of the doors, flows out into the corridor and the hall, and returns from the exhaust port of the first floor panel to the air conditioner via the exhaust duct. Then, after the temperature is adjusted, it again flows out into the room through the air supply duct.

Further, an air conditioner is installed outside the building, the base end of the air supply duct is connected to the upper part of the air conditioner, and the base end of the exhaust duct is connected to the lower part. . Further, inside thereof, a blower unit for circulating air from the exhaust duct side to the air supply duct side, a ventilation unit for ventilating the air with the outside air, and a heat exchange for heating or cooling the air. And a heat exchanger is connected to the outdoor heat source unit.

According to such an air conditioning system, the air in the building sucked into the air conditioner by the exhaust duct is ventilated and heated or cooled in the air conditioner, and then the air supply duct is again provided. And is supplied to each room of the building from the air supply duct, so that each room is maintained at a predetermined temperature.

[0008]

By the way, in this type of air conditioning system, particularly in a heat pump type air conditioning system using outside air as a heat source, it is difficult to obtain a large heating capacity, and moreover, it is not limited to each room but the corridor. Since the entire building including spaces such as halls and halls is air-conditioned, it cannot be effectively dealt with especially when the rising load is large, such as heating in the early morning of winter, it takes a long time to raise the temperature of the living room to a predetermined temperature. It has the drawback of taking time.

When it is desired to quickly raise the temperature of one room, the damper provided at the outlet of the room is fully opened,
A possible method is to fully close the dampers of other rooms to introduce warm air into the room, but in this case as well, in the above-mentioned air conditioning system, the air in the room leaks to the corridor or hall. In this system, the leaked air is collected and circulated by the exhaust duct. Therefore, it is difficult to rapidly heat the room because the air in the corridor, the hall and the like also needs to be heated.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an air conditioning system which can achieve the demand for rapidly cooling and heating only one room without inconvenience.

[0011]

In order to achieve the above object, in the invention according to claim 1, a dedicated suction port is provided in one of the living rooms in addition to a collective suction port provided in a staircase or a hall, and the suction is performed. Adjust the opening of the damper installed at the inlet so that the amount of air from this inlet is the same as the amount of conditioned air blown out from the outlet provided facing this room. It is characterized in that a damper opening adjusting means is provided.

The invention according to claim 2 is characterized in that a dedicated blow-in port provided in one of the living rooms is provided so that the position thereof can be changed in the vertical direction.

[0013]

According to the above-described air conditioning system, a dedicated blow-in port is provided in one of the rooms and a damper is provided in the room, in addition to the collective intake port, so that conditioned air is circulated only in this room. It becomes possible to centrally heat and cool. That is, the damper of the outlet facing the other room is fully closed,
By opening only the opening of the damper of the air outlet facing this room and sucking only the amount of air blown out from the air outlet from the dedicated intake port provided in this room, this room will be centrally cooled and heated. It becomes possible to do.

According to the air conditioning system of the second aspect of the present invention, the position of the dedicated blower opening is vertically shifted and switched during cooling and heating, so that the conditioned air is flowed throughout the living room. This makes it possible to efficiently air-condition the entire living room.
