DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
Regarding perimeter air conditioners that prevent dew condensation occurring on outer windows,
More specifically, the air outlet and the air inlet of the perimeter air conditioner are provided in the gap between the curtain and the outer window.

[0002]

2. Description of the Related Art In hotel rooms, halls, restaurants, and the like, wide windows are provided to secure a view. However, if the outer window is provided with a large area, the heat insulating effect is reduced, and the indoor space near the outer window is directly affected by the outside air. In particular, in a cold region, when the outside air temperature is low, the temperature in the region (perimeter zone) near the outside window decreases. For this reason, the perimeter zone
A perimeter air conditioner is provided separately from the center area (interior zone) of the room, and measures are taken to cope with load fluctuations due to the influence of outside air.

[0003] When the perimeter air conditioners are of the fan coil type using cold and hot water as a heat source, they are generally installed on the waist wall portion below the outer window. In this case, a plurality of perimeter air conditioners are arranged at predetermined intervals in the direction of the frontage of the outer window. In the perimeter zone in which the perimeter air conditioner is installed in this manner, air that has been heat-exchanged by hot water is blown out from the upper portion of the perimeter air conditioner, and the blown air rises in the ceiling direction with a gap inside the outer window. become. As a result, a warm air flow is formed between the perimeter air conditioner and the ceiling, and the heat radiation of the perimeter zone that passes through the outer window and escapes to the outside is reduced, and the perimeter zone is prevented from cooling. is there. In such a case, providing a curtain on the room side of the outer window is also an effective means for reducing heat radiation from the room.

[0004]

However, since the warm air flow is blown directly from the perimeter air conditioner, a considerable gap is formed between the outer window and the warm air flow. For this reason, there is no direct heating effect on the outer window, and when the outer window is cooled by outside air, a large amount of dew is generated on the glass surface on the indoor side due to a difference from the indoor temperature, and the downdraft ( Cold Draft).
This dew condensation clouded the outer window and blocked the view, so that the landscape was impaired, and the feet were cooled by cold draft, making the living room environment extremely unpleasant.

If a curtain is provided on the indoor side of the outer window, an air layer is formed in the gap between the outer window and the curtain, and this air layer blocks heat radiation to the outside. However, when the air blown out from the perimeter air conditioner is blown into this gap, the blown air flows into the room from this gap, which is a closed space, and the curtain shakes, and as a result, the efficiency of heat dissipation is reduced. This causes a so-called cold draft in which cool air flows into the room. Then, the curtain comes into contact with the outer window due to shaking, and at this time, if the outer window is dewed, the curtain may be wet. The present invention has been made in view of the above circumstances, and can prevent dew condensation on the outer window,
An object of the present invention is to provide a curtain swing prevention perimeter air conditioner that can prevent the curtain from swinging and cold draft by preventing the flow of air from the gap between the curtain and the outer window.

[0006]

In order to achieve the above object, a curtain swing preventing perimeter air conditioner according to the present invention has a fan coil unit provided near a lower portion of an outer window provided with a curtain on the indoor side. In the perimeter air conditioner, the fan coil unit is covered with a fan coil counter extending in the frontage direction of the outer window, and an outlet chamber connected to the outlet of the fan coil unit is provided in the fan coil counter across the frontage direction of the outer window, A blow slit is provided in the blow chamber to blow the blow air over the frontage of the outer window, and a gap for blowing the blow air from the blow slit toward the ceiling along the outer window surface is provided between the fan coil counter and the outer window. Open and communicate with the fan coil counter space, which is the fan chamber of the fan coil unit. It is characterized in the provision of the inlet in the gap between the curtain and the outer window.

[0007]

When the dew condensation preventing perimeter air conditioner is operated for heating, high temperature air is blown out from the fan coil unit,
Hot air is blown from the blowing slit to the lower end of the outer window through the blowing chamber in the frontage direction. The hot air hitting the outer window is blown out from the gap between the fan coil counter and the outer window, forming a warm airflow along the glass surface of the outer window, and the surface temperature of the glass surface is lower than the indoor dew point temperature. As a result, the glass surface is brought into a state where dew condensation hardly occurs. Further, in a state where the curtain is closed, when the air blown out of the blow slit is blown into the gap between the curtain and the outer window, the blown air blown into the gap is sucked into the suction port. As a result, the volume of air in the gap is kept constant, the curtain does not sway, the cooling air does not flow from the gap, and cold draft in the perimeter zone is prevented.
