Abstract

PURPOSE:To prevent a cooled air from blowing off to a suction port and eliminate the generation of bedewing and dripping at the suction port even when a fan is stopped. CONSTITUTION:An open air intake port 8 is installed to a main body 3 which comprises a fan 1, a heat exchanger and the like where a guide 9 is installed to the open air intake port 8 so that the open air may flow in the same direction of the air current blown off from the fan.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner having an outside air intake, and more particularly to an air conditioner having a main body of an air conditioner installed on a ceiling.

[0002]

2. Description of the Related Art An example of a conventional air conditioner having an outside air intake port is shown in FIG.

A main body 3 including a blower 1, a heat exchanger 2 and the like is installed in a ceiling, and a panel 6 including a suction port 4 and an outlet 5 is installed on a ceiling surface 7. Outside air treatment air conditioner (not shown)
The outside air intake 8 for supplying the outside air conditioned by the main body 3
It is installed in the suction side passage.

The outside air from the outside air intake 8 and the air in the inside from the intake port 4 are air-conditioned by the blower 1 and the heat exchanger 2 and blown out into the room from the outlet 5 to adjust the room temperature.
An apparatus of this type is disclosed in Japanese Utility Model Laid-Open No. 61-13217.

[0005]

In the above prior art, the outside air is treated during the middle period, during the nighttime, and the like when the cooling load is small, and the capacity is sufficient only with the cold air. In such a case, the blower is stopped, and the cool air that has been treated with the outside air does not pass through the blower or heat exchanger with high passage resistance, but blows out into the room through the suction port with low passage resistance, so that room temperature adjustment is sufficient. Can not.
In addition, since there is no heat insulating material around the suction port because it normally sucks indoor air, there is a problem that when the suction port is cooled by cold air that has been treated with the outside air, dew is formed on the suction port due to dew condensation.

An object of the present invention is to eliminate the problems of the conventional example.

[0007]

In order to achieve the above object, the present invention has a structure in which an outside air intake port is installed in a blow-out side passage, a guide is provided in the outside air intake port, and the outside air flows in the same direction as the blower blown air flow. And

[0008]

In the present invention, the outside air intake is installed in the outlet side passage, the guide is provided in the outside air intake, and the outside air is made to flow in the same direction as the blower blown air flow. Therefore, even when the blower is stopped Flows to the downstream side (outlet side). As a result, no cold air is blown out to the suction side, and there is no dew condensation on the suction port.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIG.

A main body 3 including a blower 1 and a heat exchanger 2 is installed in a ceiling, and a panel 6 including a suction port 4 and an outlet 5 is installed in the main body 3.
Is installed on the ceiling surface 7 at the lower part of the main body 3, the outside air intake 8 is installed on the upper wall between the blower outlet of the blowout side passage of the main body 3 and the heat exchanger 2, and the guide 9 is installed at the outside air inlet 8 Install so that outside air flows in the same direction as.

Reference numeral 10 is a drain pan for receiving condensed water generated when the heat exchanger 2 is cooled, 11 is a wind direction adjusting blade for adjusting the direction of the blown airflow of the blowout port 5, and 12 and 13 partition the suction side passage and the blowout side passage. A partition plate, 14 is an air filter for filtering the room air sucked from the suction port 4, usually the suction port 4
The indoor air from is filtered by an air filter 14 installed at the suction port 4, passes through the blower 1, is conditioned by the heat exchanger 2 together with the outside air treated from the outside air intake 8, and is discharged from the outlet 5 to the inside of the room. Blow out to. In the meantime, during the period when the cooling load is low, such as in the middle of the night, at night, the capacity is sufficient with only the cold air treated. In such a case, the blower 1 is stopped, and the cold air that has been treated with the outside air flows to the downstream side (outlet side) by the guide 9 provided at the outside air inlet 8, passes through the heat exchanger 2, and the outlet 5
Blew out more indoors.

[0012]

As described above, the present invention has the following effects.

When the air blower is stopped at a time when the cooling load is small, such as in the middle of the night, and when the air is cooled only by the cool air that has been treated with the outside air, the cool air is blown out in the same direction as the blower blown air flow by the guide installed at the outside air intake. Therefore, there is no blowing of cold air that has been treated with outside air to the suction port, and there is no problem of dew condensation or dew drop on the suction port.
