1 to 3 together, the outdoor unit 100 according to the present embodiment is operated together with an indoor unit (not shown) to perform air conditioning for the room.

The outdoor unit 100 includes a case 110, an air supply duct 120 formed in the case 110, an exhaust duct 130, a heat exchange element 140, and an air supply heat exchanger 150. , An outdoor heat exchanger 160, a double suction centrifugal fan 170, and a compressor 190.

The case 110 has an external air inlet 111 through which external air is introduced. The external air inlet 111 is formed at approximately the center of the case 110. In addition, the case 110 is formed with a grill 112 through which outside air is introduced. The grill 122 is formed separately from the external air inlet 111 in a substantially lower portion of the case 110.

The outside air introduced through the outside air inlet 111 passes through the electrothermal exchange element 140 and is then supplied to the room through the air supply duct 120. In addition, the outside air introduced through the grill 122 passes through the outdoor heat exchanger 160 and the double suction centrifugal fan 170, and then is discharged again to the outside.

The air supply duct 120 is formed above the case 110. The air supply duct 120 is provided with an air supply fan 124 inside the main body 121. Outside air may flow by the air supply fan 124. An air supply outlet 122 is formed above the air supply duct 120, and an air supply suction port 123 is formed below the air supply duct 120 near the air supply fan 124.

When the air supply fan 124 is operated, external air is introduced through the air supply inlet 123 and discharged to the air supply outlet 122 through the main body 121. The air discharged through the air supply outlet 122 may be supplied to a room along a predetermined duct (not shown).

The exhaust duct 130 is formed on one side of the air supply duct 120. The exhaust duct 130 is a portion in which air moved along a predetermined duct (not shown) in the room is introduced. An indoor air inlet 133 is formed above the exhaust duct 130.

In the vicinity of the indoor air inlet 133, a panel-shaped inlet forming unit 132 is formed, and a partition wall 131 is formed to form a shape in which the inlet forming unit 132 is connected. The partition wall 131 isolates each flow path of the outside air introduced into the air supply duct 120 and the indoor air introduced / discharged into the exhaust duct 130.

The total heat exchange element 140 performs a total heat exchange between the air introduced through the external air inlet 111 and the indoor air introduced through the exhaust duct 130. By such heat exchange, the temperature of the outside air supplied to the room can be adjusted similarly to the temperature of the room.

In other words, when cooling is performed for the room, the temperature of the indoor air introduced through the air supply duct 120 is relatively low, and the temperature of the external air introduced into the external air inlet 111 is relatively high. As these two air exchanges heat in the total heat exchange element 140, the temperature of the outside air can be lowered. Therefore, since the outside air supplied to the room is in a state where the temperature is lowered, the air flow and the comfort can be improved.

In addition, when the heating is performed for the indoor, the temperature of the indoor air introduced through the air supply duct 120 is relatively high, and the temperature of the external air introduced into the external air inlet 111 is relatively low. As these two air exchanges heat in the total heat exchange element 140, the temperature of the outside air can be increased. Therefore, since the outside air supplied to the room is in a state where the temperature is high, the air flow and comfort can be improved, and a cold draft phenomenon can be prevented.

The reference numerals 141, 142, 143 and 144 shown refer to the respective surfaces of the electrothermal exchange element 140, which are the first surface 141, the second surface 142, the third surface 143 and It may be defined as the fourth surface 144.

The air supply heat exchanger 150 is installed on the flow path of the outside air of the total heat exchange element 140.

In the present embodiment, the front air supply heat exchanger 151 is provided near the first surface 141 of the electrothermal heat exchange element 140, and the rear air supply heat exchanger 152 is provided near the third surface 143.

When cooling is performed to the room, the refrigerant passing through the expansion valve 250 heats the outside air in the air supply heat exchanger 150, thereby lowering the temperature of the outside air. Then, since the temperature of the outside air supplied to the room is lowered, the air flow and the comfort can be improved.

When heating is performed in the room, the refrigerant passing through the compressor 190 heats the outside air in the air supply heat exchanger 150, thereby raising the temperature of the outside air. Then, since the temperature of the outside air supplied to the room is increased, the airflow feeling and comfort are improved, and the cold draft phenomenon can be prevented.

On the other hand, the air supply duct 120, the exhaust duct 130, and the heat exchange element 140 is a portion capable of performing a ventilation function for the room, it may be defined as a ventilation unit.

In response to the ventilation unit, the outdoor heat exchanger 160, the double suction centrifugal fan 170, and the compressor 190 exchange cooling units with an indoor unit and perform cooling / heating functions with respect to the room. In part, it may be defined as an outdoor heat exchanger.

The electrothermal exchange element connection panel 182 is connected to the lower portion of the electrothermal exchange element 140 to isolate the front and rear sides of the electrothermal exchange element 140. The horizontal panel 181 isolates the vent / outdoor heat exchanger.

In the outdoor heat exchanger 160, the refrigerant flowing through the inside, the outside air introduced through the grill 112, and the indoor air via the total heat exchange element 140 are heat-exchanged. The outdoor heat exchanger 160 may be installed at the front / rear side of the double suction centrifugal fan 170 to improve heat exchange efficiency.

The reference numeral 161 shown is the front outdoor heat exchanger, and 162 is the rear outdoor heat exchanger.

When cooling is performed indoors, the refrigerant passing through the compressor 190 exchanges heat with external air in the front outdoor heat exchanger 161 and heat exchanges with indoor air in the rear outdoor heat exchanger 162. Dissipate heat from outside.

When the heating is performed indoors, the refrigerant passing through the expansion valve 250 is heat-exchanged with the outside air in the front outdoor heat exchanger 161, and heat exchanged with the indoor air in the rear outdoor heat exchanger 162, Absorbs outdoor heat and residual heat from indoor air.

The double suction centrifugal fan 170 includes a fan duct 173, a fan blade 172 installed therein, and a discharge port 171. When the double suction centrifugal fan 170 is operated, the indoor air passing through the rear outdoor heat exchanger 162 and the external air passing through the front outdoor heat exchanger 161 are sucked in to the outside through the discharge port 171. To be discharged.

On the other hand, the reference numeral 200 is a connection pipe 200 is connected to the other components from the compressor 190.

Flows through 142 and out through fourth surface 144. Through this inflow / outflow process, the heat exchange between the outside air and the indoor air in the heat exchange element 140 is made.

Here, the outside air is heat exchanged with the refrigerant flowing therein in the air supply heat exchanger (150).

On the other hand, in order to perform the cooling / heating function, the power is applied to the double suction centrifugal fan (170). Then, outside air is introduced through the grill 112. Then, indoor air flows through the electrothermal exchange element 140.

The outside air introduced through the grill 112 and the indoor air introduced through the electrothermal exchange element 140 pass through the front / rear outdoor heat exchangers 161 and 162, respectively. At this time, the refrigerant flowing through the front / rear outdoor heat exchangers 161 and 162 and the external air / the indoor air are heat-exchanged.

The indoor air and outdoor air heat-exchanged as described above are introduced into the double suction centrifugal fan 170, and are discharged to the outside through the discharge port 171 through the fan duct 173.
