Description

[Detailed description of the device] [Industrial applications]

The present invention relates to an installation structure for installing a fan coil unit in a peri-counter provided below a window glass of a perimeter.

[Prior art and its problems]

Generally, in a building, in order to respond to various air conditioning conditions such as air conditioning heat load characteristics, purpose of use, or usage time at each place in the building, they are divided into areas and each system has a separate air conditioning system. Zoning is being provided. Of these zonings, the zoning by load characteristics is the outer peripheral part near the outer wall of the building, namely the perimeter (this may be subdivided according to the north, south, east, and west directions), and the center of the building away from the outer wall It can be divided into parts or interiors. A fan coil unit is widely used as an air conditioner for a perimeter, from the viewpoint of easy zoning and excellent individual controllability. By the way, during the heating operation in winter, the room temperature tends to drop due to the temperature difference between the room and the outside air, and one of the major heat transfer mechanisms is that the heat of the air near the window glass is transferred from the window glass. It may be transmitted to the outside air. Therefore, even in the same room, a temperature difference occurs in the air between the window glass and other portions, and a difference in specific gravity occurs in the air between those portions. Therefore, a so-called cold draft occurs in which cooled air near the window glass, which has a larger specific gravity than warm air, descends from the ceiling side toward the floor side. Here, the relationship between the installation structure of the fan coil unit and the cold draft in the prior art will be described with reference to FIGS. 2 (a) and (b) and FIGS. 3 (a) and (b). 2 (a) and 2 (b) are perspective views showing an installation example in the case where a floor-standing fan coil unit between columns of a perimeter is installed and a simplified cross-sectional view showing its air flow, and FIG. 3 (a). And (b) is a perspective view showing an installation example in which a peri-counter is provided between columns and a floor-standing fan coil unit is installed therein, and a simplified cross-sectional view showing the air flow thereof.
Shown respectively. First, in the case where the floor-standing fan coil unit 31 is installed between the columns 30 of the perimeter, FIG.
An explanation will be given using (b). As shown in FIG. 2 (b),
The fan coil unit 31 is installed on the indoor side of the waist wall 33 of the skeleton 32, sucks indoor air from the suction port provided in the lower part of the main body, and converts it into warm air inside the main body to blow the air over the upper part of the main body. It blows upward from the outlet 34 (Fig. 2 (a)). The warm air blown upwards eventually collides with the ceiling, and is split into an air flow toward the center of the room indicated by the arrow 35 on one side and an air flow toward the window glass 37 side indicated by the arrow 36 on the other side. Of these airflows, the airflow toward the window glass 37 further descends along the glass surface to drive the cold air from that portion from there and, together with the warm air blown from the outlet 34, disturbs the airflow in that portion. . Therefore, these hot air and the cold air around the window glass 37 are mixed to prevent the generation of cold draft. On the other hand, in a portion between both sides of the fan coil unit 31 and each of the columns 30, 30, since there is no warm air that is blown out of the fan coil unit and rises, there is no phenomenon such that cold air and warm air mix. As indicated by the arrow 38 in FIG. 2 (a), the cold air near the window glass moves downward as it is to cause cold draft. This means that the fan coil unit 31
The same is true for the case shown in FIGS. 3 (a) and 3 (b) in which the column 3 is provided.
Cold draft 38 will occur between 0 and 30. Specifically, the cold draft generated as described above has a velocity of about 0.5 m / sec near the floor surface, and further moves from there toward the center of the room. Therefore, the presence of the cold draft reduces the heating effect of the room, and causes discomfort to the occupants or users in the room who are directly in contact with the cold air. The present invention was created in order to effectively solve the above-mentioned conventional technical problems. Therefore, an object thereof is to provide an installation structure of a fan coil unit for effectively preventing the generation of cold draft near the window glass.

[Means for Solving the Problems]

The installation structure of the fan coil unit according to the present invention is configured as follows to achieve the above object. That is, the floor-standing fan coil unit is installed along the waist wall below the window, and at least the width of the window is provided between the floor surface and the wall surface of the waist wall in order to conceal the fan coil unit. A peri-counter is formed. Then, in the peri-counter, the cool air that descends along the window is supplied to the fan coil unit and converted into warm air,
An intake port for sucking the cool air into the peri-counter is provided. In addition, the fan coil unit installed in the fan coil unit installation structure according to the present invention is not limited to the dedicated heating machine, and it is of course possible to perform normal cooling operation by passing cold water through the heat exchanger (coil). Is.

[Action / effect]

When heating the interior of the room with the fan coil unit having the above-described configuration, cold air is also generated near the window due to the temperature difference from the outside air, as in the case of the conventional fan coil unit. On the other hand, the generated cool air descends from the upper side to the lower side of the window due to the difference in specific gravity from warm air, and is further sucked into the peri-counter through the intake port provided in the peri-counter. In this case, since the peri-counter is provided so as to be aligned with at least the width of the window, the cool air generated in the window portion is
Even those generated outside the hot air outlet of the fan coil unit are sucked into the peri-counter. Then, the sucked cool air is supplied to the fan coil unit, heat is exchanged inside the fan coil unit, and is blown into the room as warm air from the air outlet. In this way, according to the above configuration, the generated cool air can be converted into hot air and blown out without being released to the interior side,
It is possible to completely prevent the generation of cold draft, which causes discomfort to the occupants, and effectively prevent a decrease in heating effect.

【Example】

An embodiment of the present invention will be described below with reference to FIG. FIG. 1 is a schematic vertical cross-sectional view of a central portion showing the installation structure of a fan coil unit according to an embodiment of the present invention. As shown, this floor-standing fan coil unit 1
Is installed in a peri-counter 3 provided with the same width as the window glass 2 below the window glass 2 between columns (not shown) of the perimeter. In this case, the fan coil unit 1
As is the case with FIG. 3, the device itself is narrower than the peri-counter 3, and therefore, parts inside the peri-counter 3 on both sides of the fan coil unit 1 are hollow. Further, the fan coil unit 1 sucks in the indoor air through the air suction port 14 having the filter 4 provided in the lower part thereof, and converts the air into warm air through the heat exchanger 5 by a blower (not shown), The warm air is blown toward the ceiling from the air outlet 7 fitted in the top plate 6 of the pericounter 3. Further, the peri-counter 3 in which the fan coil unit 1 is installed is configured such that the top plate 6 is located higher than the window stand 10 which is the upper surface of the waist wall 9 of the body 8. Inlet 11 between 6 and window stand 10
Is provided with an opening. In addition, this intake port 11
It is formed over the entire range in which the peri-counter 3 is provided, that is, the entire range between columns. Further, an air intake 13 for supplying indoor air to the fan coil unit 1 is formed in the lower portion of the front plate 12 constituting the peri-counter 3 with the same width as the fan coil unit 1. On the other hand, the fan coil unit 1 is installed inside the peri-counter 3 apart from the waist wall 9, and a space serving as an intake passage 16 is formed between the fan coil unit 1 and the waist wall 9. Become. Therefore, in the fan coil unit 1, not only the air intake port 13 but also the intake port 11 from the top plate 6 of the peri-counter 3 and the window stand 10 to the intake passage 16
Air is supplied through the hollow portions located on both sides of the fan coil unit 1. The air conditioning by the fan coil unit 1 installed with the above configuration is particularly effective in preventing cold draft during heating operation. The heating operation in winter will be described below. As described above, when the room is heated, the temperature of the air near the window glass 2 decreases due to the temperature difference from the outside air. In the above configuration, since the hot air outlet 7 is provided on the upper surface 6 of the peri-counter 3, the hot air blown out cooperates with the hot air descending from the ceiling to cool the air as described above. To prevent the generation of Cold Draft 15. On the other hand, since there is no warm air rising near the window glass between the air outlet 7 and each pillar, the cold air in that portion tries to move downward as it is. By the way, when the fan coil unit 1 is operated, the inside of the peri-counter 3 including the intake passage 16 becomes negative pressure. Therefore, the cold air generated near the window glass moves from the upper part of the window glass to the lower part due to the difference in specific gravity with the warm air in the room, and when it reaches the lower part of the window glass, not only the difference in specific gravity The negative pressure forces the air to be sucked into the peri-counter 3 through the intake port 11 formed near the window glass of the peri-counter 3. The cold air sucked into the peri-counter 3 is the waist wall 9
Through the air intake path 16 between the fan coil unit 1 and the fan coil unit 1 and the hollow portions on both sides of the fan coil unit 1, and is sucked into the main body of the fan coil unit 1 from the air suction port 14 through the filter 4. In this case, the air intake
Since 13 is formed with the same width as the fan coil unit 1, the cold air that has entered the cavity does not escape into the room and the intake path
It is sucked into the fan coil unit 1 after being mixed with the cool air that has passed through 16 or the indoor air that has passed through the intake port 13. Then, the cool air sucked into the fan coil unit 1 is converted into warm air by being given heat when it is passed through the heat exchanger 5 by a blower (not shown) inside the cool air, and further from the outlet 7 to the ceiling. It is blown out as warm air. As described above, according to the above configuration, all the cool air that is going to descend from the window glass 2 is completely removed from the fan coil unit 1.
It is possible to completely prevent the generation of cold draft since it can be supplied to the air conditioner and converted into warm air.
