Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a ceiling-embedded air conditioner installed in the attic of a building office or the like.

BACKGROUND ART Conventionally, this type of ceiling-embedded air conditioner has a configuration as shown in FIG. 2, for example. That is, the main body 2 of the air conditioner is suspended in the ceiling 1 by a hanging device (not shown), and the main body 2 is equipped with a blower 3 for indoor circulation and a supply of hot and cold water or refrigerant. A heat exchanger 4 is provided, and a grill 6 is connected to the main body 2 and attached to the ceiling surface 5. This grille 6 is provided with an inlet 8 that flows in from the indoor room 7 and an outlet 9 through which cold and hot air passes through the heat exchanger 4 and is blown out into the indoor room 7. On the other hand, a heat exchange air unit 10 for ventilation is provided at a certain distance from the main body 2, a total heat exchanger 11 (dotted line) is provided inside, and a first exhaust duct 12 and a first air supply duct are provided on one side. A chamber 14 to which an air duct 13 is connected is provided. Inside this chamber 14, there is a partition plate 15 that separates intake and exhaust air, an exhaust port 17 that exhausts indoor air to a chamber grill 16 attached to the ceiling surface 5, and an air supply port 18 that supplies outside air. The exhaust port 17 and the duct 12 are in communication with each other, and the air supply port 18 and the duct 13 are in communication with each other. In addition, heat exchange air unit 1
On the other side of 0, a second air supply duct 19 and a second exhaust duct 20, which are disposed on the outdoor side, are provided.

In this way, conventionally, the main body 2 of the air conditioner is installed in the attic 1 and the room is air-conditioned from the ceiling surface 5.
For indoor ventilation, the second air supply duct 1 is used to supply outside air.
9, the air flows obliquely downward from the air supply surface 11a of the total heat exchanger 11 provided inside the heat exchange air unit 10,
It flows into the chamber 14 from the first air supply duct 13 and is blown into the room from the air supply port 18, while the exhaust port 1
Indoor air flowing in from the first exhaust duct 12 flows obliquely downward from the exhaust surface 11b of the total heat exchanger and goes around to the second exhaust duct 20 side, and is exhausted to the outside to supply and exhaust the indoor air. The air conditioning and supply/exhaust systems were installed in the building.

Problems to be Solved by the Invention In such a conventional configuration, the air conditioner body 2 and the heat exchange air unit 10 are provided independently in the attic 1, so an air conditioning grill is installed on the ceiling surface 5. 6, and an opening for the grill 16 for the heat exchange air unit 10 must be provided, and the construction cost and material cost for both the grills 6 and 16 are very high, and it is also undesirable in terms of the design of the ceiling surface. There were some problems, such as not having one.

This invention solves these problems,
The aim is to reduce construction and material costs by sharing grills.

Means for Solving the Problem In order to solve this problem, the present invention includes a main body of a ceiling-embedded air conditioner, and a grille that is joined to the main body and the ceiling surface and has an inlet and an outlet. , the grille is extended toward the side where the heat exchange air unit is provided, and an air supply/exhaust port corresponding to the supply/exhaust chamber connected to the heat exchange air unit by a duct is provided in the extended portion. and an exhaust port.

Function: With this configuration, indoor air for air conditioning is circulated through the inlet and outlet of the grill connected to the main body of the air conditioner, while heat exchange is performed through the exhaust outlet provided in the extension of the grill. The air is exhausted to the heat exchange air unit side, while the outside air that has flowed in from the heat exchange air unit side is supplied to the indoor side from the air supply port side.

Embodiment An embodiment of the present invention will be described below with reference to FIG. In the figure, 22 is a main body 22 of an air conditioner suspended in a ceiling 21 of a building, etc. Inside this main body 22, a blower 23 for indoor air circulation and a heat exchanger 24 are installed, and a ceiling A grille 26 is provided with the surface 25 opened. This grill 26 has the heat exchanger 24
A suction port 28 that sucks air from the room 27 corresponding to the
and an air outlet 29 through which air is blown out into the room 27 through the heat exchanger 24. Further, the grille 26 has an extended portion 31 extending in the longitudinal direction so that a chamber 30 for air supply and exhaust is located. A chamber 30 is provided in the extension portion 31, and a partition plate 34 is provided in the chamber 30 to partition an exhaust port 32 for exhausting indoor air and an air supply port 33 for taking in outside air and supplying the air into the room. ing. a first exhaust duct 35 communicating with the exhaust port;
is connected to the heat exchange air unit 35, and a first air supply duct 36 communicating with the air supply port 33 is connected to the heat exchange air unit 35. The heat exchange air unit 35 is provided with a total heat exchanger 37 inclined at an angle of 45 degrees, and the air flowing in from the first exhaust duct 35 flows downward through the exhaust surface 37a of the total heat exchanger 37, and the second exhaust The air goes around the duct 38 side and is exhausted to the outside, while the air is supplied from the air supply duct 39 to the air supply surface 3.
7b and flows upwardly into the first air supply duct 36. 40 is an auxiliary pipe provided in the heat exchanger 24.

In the above configuration, on the main body 22 side of the air conditioner, the blower 23 is operated while passing cold and hot water or refrigerant.
When the engine is operated, the air is blown into the room from the suction port 29 provided in the grille 26 joined to the ceiling surface 25. On the other hand, an extended portion 31 integrated with the grille 26 is provided with an air supply port 33 and an exhaust port 32 separated by a partition plate 34, and the chamber 30
Provide. The same applies when the main body 22 and the chamber 30 are integrated. Then, by operating a supply/exhaust blower (not shown) connected to the second air supply duct 39 and the second exhaust duct 38, the exhaust flow path sucks indoor air from the exhaust port 32 to the first exhaust duct. 35 into the heat exchange air unit 35, and the exhaust surface 37a of the total heat exchanger 37.
It passes diagonally downward and is exhausted to the outside from the second exhaust duct 38. Similarly, outside air flows in from the second exhaust duct 39, flows into the heat exchange air unit 35, passes through the air supply surface 37b, flows diagonally downward, passes through the first air supply duct 36, and enters the air supply port 33. Fresh air is blown into the room, as well as air whose heat amount has been recovered when exhausted by the total heat exchanger 37.

Effects of the Invention As is clear from the description of the embodiments described above, the present invention includes a main body of an air conditioner and a grill provided on the ceiling surface having an air conditioning inlet and an air outlet. The air conditioning and ventilation system is equipped with an air supply and exhaust port in each section, as well as a corresponding chamber for supply and exhaust, so the grill installed on the ceiling can be covered by a single grill, making construction easier. Moreover, construction costs are low, and the cost of grill materials is significantly reduced. Moreover, compared to the case where the air supply and exhaust ports are provided at large intervals on the ceiling surface, it has the effect of being easier to put together in terms of design.
