However, the following embodiments are provided only to those skilled in the art to fully understand the present invention, and the scope of the present invention is not limited to the embodiments described below. .

Figure 2 is a schematic diagram of a ceiling jet air conditioning apparatus according to the present invention. As shown in Figure 2, the ceiling jet air conditioner according to the present invention is a suction grill (1), the outside air inlet (2), air filtration filter (3), heat exchanger (4), blower (5), noise chamber (6) and a variable swing-out outlet 7 is included.

Each part is demonstrated below.

The suction grill 1 is a suction port that sucks indoor air.

Suction grill (1) is attached to the lower portion as shown in Figure 2 to attach to the ceiling when there is a ceiling finish, if there is no ceiling finish can be installed suction grill (1) on the side.

Outside air inlet (2) is a blower that can introduce fresh outside air by connecting a ventilation duct when ventilation or outside air cooling is required.

The air filtration filter 3 is installed for the purpose of preventing contamination of the heat exchanger by filtering dust in indoor air or outside air. Since the air filtration filter 3 is installed at a height, it is difficult to periodically clean and replace it, so it is preferable to install a long life filter.

The heat exchanger (4) serves to cool or heat the air by heat-exchanging the cold or hot water or refrigerant supplied from the outdoor unit with the indoor air. The blower 5 serves to blow air in a motor direct type or a belt drive type.

The noise chamber 6 serves to absorb noise generated by the blower 5.

When the variable swing type outlet 7 is automatically operated, a temperature sensor is installed at the rear end of the heat exchanger 4 so that the heating switch is automatically switched to the heating mode by sensing the temperature of the temperature sensor. Open the vertical turning to take out the air flow to the residential area, and when the cooling is switched to the cooling mode automatically by sensing the temperature of the temperature sensor. In the cooling mode, the damper 10 is opened and the horizontal turning is taken out. This makes it possible to uniformly cool by widening the air flow diffusion radius. It can also be manually adjusted by electric damper operation in the center.

The damper 10 of the variable swing outlet 7 is for selecting a vertical or horizontal air stream for each season and is driven by electric power. The inclined blade 11 forms a swirling air stream vertically or horizontally to a distant living area. The air flow is to reach. The airflow rectifying plate 12 under the damper 10 has a grid-like guide shape so that vertical airflow is formed during heating, so that warm air can reach the residential area.

Hereinafter, the operation of the air conditioning apparatus according to the present invention will be described. First of all, heating operation is selected by remote controller or computer controller, and after setting the desired indoor temperature, the outdoor unit is started and the heating preparation mode flashes on the remote control, and the blower (5) of the air conditioner is activated and attached to the heat exchanger (4). The automatic flow control valve of the heated heat source is opened, and the indoor air sucked into the suction grill (1) and the outdoor air sucked into the outside air intake port (2) pass through the air filtration filter (3), and dust is filtered out. In case of heating and automatic mode, the mode of the outlet 7 is automatically set to the heating mode by the temperature sensor installed at the rear end of the heat exchanger 3, and the damper 10 of the outlet is opened to incline the blade 11 and the airflow rectification. As the vertical heating blower flows through the plate 12 and reaches the residential area, the heating is smoothly performed.

In the cooling operation, select the cooling mode with a controller such as a remote control or a computer and set the desired room temperature. The outdoor unit is operated, the blower 5 of the jet air conditioner is operated, and the flow rate automatic control valve of the heat source attached to the heat exchanger 4 is operated. When the indoor air sucked into the open suction grill (1) and the outdoor air sucked into the outside air intake (2) pass through the air filtration filter (3), dust is filtered out, and is cooled while passing through the heat exchanger (3), and is an automatic system. The outlet 7 mode is automatically set to the cooling mode by the temperature sensor installed at the rear end of the heat exchanger 3, and the damper 10 of the outlet 7 is closed, and is blown out horizontally while passing through the inclined vane 11 to cool down the airflow. The diffusion radius of the wider cooling is carried out smoothly.

Of course, the outlet mode can manually select the seasonal heating and cooling mode in the center.

If you want to reduce the noise or to save energy, the controller can achieve the purpose by adjusting the air volume of the inverter motor blower or BLDC motor blower (5).
