Abstract

PROBLEM TO BE SOLVED: To achieve an effective utilization of a space with the curtailing of air conditioning equipment costs by a method wherein a blowoff port is provided on the ceiling of a dwelling room to fill an air supply space for air conditioning with air conditioning air generated by a fan coil unit and the air conditioning air is taken in from the blowoff port to perform an air conditioning of the dwelling room. SOLUTION: A refrigerant or hot water is supplied into a fan coil unit 13 from a heat source device. The fan coil unit 13 produces air for air conditioning by heat exchange between the refrigerant or hot water and air and blows out the air into an air supply space 12 for air conditioning in the rear of the ceiling to fill it. Outside air or return air from dwelling rooms are supplied into the fan coil unit 13 via an air duct 14. Air in the air supply space 12 for air conditioning in the rear of the ceiling is blown out from a blowoff port 16 provided on the ceiling 11. The amount of air blown out can controlled, for example, by an air quantity adjusting plate mounted on the blowoff port 16 or according to the number of revolutions of a fan mounted on the blowoff port.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air-conditioning system that is easy to construct and can be easily air-conditioned such as cooling or heating by changing the air outlet when the layout or room is changed. Regarding

[0002]

2. Description of the Related Art In a conventional air-conditioning system, as shown in FIG. 3, a fan coil unit 3 is installed in a part of a ceiling 2 of a dwelling unit 1 and air outlets provided in ceilings of respective living rooms 4 and 5. 6 and 7 are connected to each other through ducts 8 and 9 and supply air conditioning air to each living room.

[0003]

Therefore, the conventional air conditioning system has the following drawbacks. a. Since the ducts 8 and 9 are installed in the ceiling, the facility cost including material cost is high. b. When there is a beam or the like in the back of the ceiling, it is necessary to bypass the ducts 8 and 9 or provide a through hole in the beam. c. Since it is difficult to change the installation route of the ducts 8 and 9 when the layout of the room is changed or the pattern is changed, it is necessary to separately install an air conditioner or the like.

[0004]

Means for Solving the Problems The present invention provides the above ac.
The purpose is to solve the above problem, and the configuration is as follows. 1. An air-conditioning air supply space is formed over the entire ceiling of the dwelling unit, an air outlet is provided in the ceiling of each living room, and the air-conditioning air generated in the fan coil unit is filled in the air-conditioning air supply space and at the same time in each living room. For air conditioning,
An air conditioning system, wherein air for air conditioning is taken into the room from the outlet. 2. 2. The air conditioning system according to 1, wherein a fan is attached to the air outlet. 3. A plurality of outlets are provided on the ceiling in advance, the outlets to be used are selected and opened, and the others are closed so that the outlets can be changed arbitrarily when the layout is changed. 3. The air conditioning system according to 1 or 2 above. 4. 4. The air conditioning system according to 1 or 2 or 3, wherein the fan coil unit is installed in an air supply space for air conditioning.

[0005]

The refrigerant or hot water is supplied from the heat source unit into the fan coil unit. The fan coil unit creates air for air conditioning by exchanging heat between the refrigerant or hot water and the air, and blows the air into the air supply space for air conditioning under the ceiling to fill the space. Outside air or return air from each living room is supplied into the fan coil unit via an air supply duct. Air in the air-conditioning air supply space behind the ceiling is blown into each living room from an outlet provided on the ceiling. The amount of air blown out can be controlled by, for example, an air volume adjusting plate attached to the air outlet, or can be controlled by the number of rotations of a fan attached to the air outlet. It should be noted that it is convenient to operate this adjusting plate or fan by using a remote controller.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example of an embodiment of the present invention. 10 is a building, 11 is a ceiling, and 12 is air conditioning air formed between the ceiling 11 and a slab 10a of the building 10. The air supply space 12, which is a supply space, is basically formed over the entire ceiling above the ceiling of the dwelling unit, and is shielded from the outside air. Reference numeral 13 denotes a fan coil unit installed in a part of the air supply space 12, and the fan coil unit 13 is supplied with a refrigerant or hot water from a heat source device (not shown). Further, air is introduced from the outside via the air supply duct 14 or from the living room via the return duct 15. Reference numeral 16 denotes an air outlet provided in the ceiling 11 of the living rooms A and B. The air-conditioning air generated in the fan coil unit 13 fills the air supply space 12, and then the air outlet 16 causes the air into the living rooms A and B. Air condition to blow out.

FIG. 2 shows an example in which, when the floor plan is changed in the living room, a new air outlet 16a is opened and air conditioning is performed from here. Reference numeral 17 is a partition wall before changing the floor plan, and 17a is a partition wall after changing the floor plan. In addition,
The old outlet 16 is blocked.

In the embodiment, the air supply space 12 and the living rooms A and B are used.
Air is supposed to blow out into the room due to the pressure difference between
A fan may be attached to the air outlet 16 to blow out the air. In the summer, the air is conditioned from the fan coil unit 13 without lowering the temperature by dehumidified air, so that the temperature difference between the two sides of the ceiling surface can be reduced, and thus dew condensation can be prevented.

[0009]

As described above, the present invention provides the following effects by forming the air-conditioning air supply space over the entire ceiling of the living room to perform air conditioning. a. Since there is usually a space above the ceiling, this space above the ceiling can be used as a space for supplying air for air conditioning.
For this reason, there is no need to construct the air-conditioning duct behind the ceiling as in the conventional case, and the cost of air-conditioning equipment can be reduced. b. Since the air outlet can be provided at any place on the ceiling surface, it is particularly convenient when changing the layout of the room or changing the pattern. c. Even if there are beams on the ceiling, the entire ceiling can be communicated as long as there is a gap between the beams and the ceiling.
There is no need to provide a hole for passing through the duct in the beam as in the conventional case. d. Since the air conditioning is performed even in summer without lowering the temperature with dehumidified air, the temperature difference between both sides of the ceiling surface can be reduced, and dew condensation can be prevented. e. By installing the fan coil unit in the air supply space for air conditioning, the space can be effectively used.
