CONSTITUTION:A heat exchanger 3 is so mounted near an air suction port 2 as to be opposed to the port 2, a warm or chilled water supply port 31 and discharge port 32 to the exchanger 3 and a drain pan 33 protrude from a surface side opposed to a corridor A of a casing 1, and a water supply tube, a drain tube are connected to the ports. A blower 5 is mounted in the vicinity of a conditioned air discharge port 4 formed at a surface side opposed to the port 2 of the casing 1. Thus, a unit body is so mounted that the exchanger 3 having a wide width does not cross a passage of an exit/entrance, and a tube space for connecting the supply tube, the drain tube to the exchanger 3 can fall within a passage space B.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a space-saving type fan coil unit which is suitable mainly for installation in a narrow space such as a guest room of a hotel.

[0002]

2. Description of the Related Art Generally speaking, a fan coil unit has a heat exchanger and a blower inside a casing having an air inlet and a conditioned air outlet. In that case, each unit only needs to supply hot or cold water from the central cab, so there are multiple rooms in one building, and it is necessary to perform optimal air conditioning for each room. Although it can be said that this is an optimal system for hotels and the like, in the conventionally known fan coil unit, as shown in FIG. 3, the air suction port a, the blower b, the heat exchanger c, and the conditioned air discharge port d are aligned. Since they are arranged, when installing this unit in a guest room of a hotel, there is a constraint that the conditioned air discharge port d must be installed facing the room side in the ceiling of the doorway, that is, the frontage side. Runode, heat exchanger c is as to face the inevitable outdoor corridor.

Facing the corridor means that the heat exchanger c
The longest width of the unit crosses the passageway of the entrance and exit of the room, and a piping space for supplying hot or cold water to the heat exchanger is required in parallel with the unit body. There is a problem in that the space becomes larger than the width, and the space of the unit bath normally provided adjacent to the entrance or exit or the space of the room adjacent to the unit bath becomes narrow.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems of the prior art, the present invention has a structure in which a heat exchanger does not cross a passageway of an inlet / outlet, and a unit space or the like adjacent to each other so that a piping space is accommodated in the passageway space. It is an object of the present invention to provide a fan coil unit in which the space is not narrowed.

[0005]

DISCLOSURE OF THE INVENTION A fan coil unit according to the present invention is
In a fan coil unit equipped with a heat exchanger and a blower inside a casing provided with an air suction port and a conditioned air discharge port, the air suction port and the conditioned air suction port are arranged so as to be orthogonal to each other, and on the air suction port side. Is equipped with a heat exchanger and a blower on the conditioned air outlet side, and the hot water or cold water supply and discharge ports to the heat exchanger are provided on the side opposite to the conditioned air outlet. To do.

[0006]

Since the heat exchanger is mounted on the side of the air suction port, the heat exchanger having a large width does not cross the passage of the inlet / outlet, and the piping space for connecting to the supply port and the discharge port is provided. Fits in the aisle space.

[0007]

[Embodiment 1] FIG. 1 is a schematic plan view of a unit of the present invention, in which 1 is a casing of a unit main body suspendedly attached to a ceiling base of a passageway of a doorway, and 2 is a corridor A of a casing 1. The air suction port is formed on the surface side that does not face with, and the filter 21 is attached to this port. Reference numeral 3 denotes a heat exchanger mounted near the air intake port 2 so as to face the air intake port 2, and a hot water or cold water supply port 31 and a discharge port 32 and a drain pan 33 for the heat exchanger are provided in the casing 1. It projects from the side facing the A, and a water supply pipe and a drainage pipe are connected to each port. Reference numeral 4 denotes a conditioned air discharge port formed on the surface side of the casing 1 orthogonal to the air intake port 2, that is, on the surface side opposite to the supply port and the discharge port, and the blower 5 is attached near this port. . In the figure, B is the passage space of the entrance and exit, and C is
The unit bath space, C ', is an inspection port provided on the ceiling of the unit bath. The operation of the unit of the present invention in air conditioning is the same as that of the conventionally known technique, but since the air suction port 2 is provided so as to be orthogonal to the conditioned air discharge port 4, it has a horizontal width that requires a large area. The unit main body is installed so that the wide heat exchanger 3 does not cross the passageway of the entrance and exit, and the piping space for connecting the water supply pipe and the drainage pipe to the heat exchanger 3 is accommodated in the passage space B. It is like this.

[0008]

[Embodiment 2] FIG. 2 is a schematic plan view showing a second embodiment of the unit of the present invention. The basic structure is the same as that of the first embodiment, but the surface side of the casing 1 opposite to the conditioned air discharge port 4 is shown. Another air intake 6 is formed in the casing, and a partition plate 7 and a bypass damper 8 for forming another passage are provided inside the casing. A motor 81 drives the bypass damper 8 to The amount of air sucked and passing through the heat exchanger 3 and the amount of air sucked from the air intake 5 are adjusted to expand the control range.

[0009]

According to the fan coil unit of the present invention, the air suction port is formed in the direction orthogonal to the conditioned air discharge port, and the heat exchanger is attached to the air suction port side. Since a wide heat exchanger does not cross the passage of the inlet and outlet, and the supply port and the discharge port are provided on the side opposite to the conditioned air discharge port, not only the unit body but also the piping space Fits in the aisle space,
Unlike the conventional unit, the unit body and the piping space do not extend beyond the width of the frontage to narrow the space of the unit bath or the like adjacent to the entrance / exit.

Further, the conventional unit requires two inspection ports for maintenance and inspection such as filter replacement and maintenance and inspection of piping including the electric wiring box and drain pan for energizing the motor of the blower. However, since the unit of the present invention has a structure in which the filter, the piping equipment, and the electric wiring box can be provided in the same direction, the inspection port need only be provided at one place on the ceiling of the unit bath on the air intake port side. In addition to the maintenance aspect, the facility effect including the electrical wiring work to the unit main body can be easily performed, which is an excellent effect in terms of construction.
