Hereinafter, the operation of the air conditioner according to the present invention as described above will be described with reference to FIG. 14.

First, look at the flow of the refrigerant and air in the air conditioner according to the present invention.

The air conditioner according to the present invention can be used for cooling or heating. Here, the case where the air conditioner according to the present invention is used for cooling will be described as an example.

In this case, the first heat exchanger 510 serves as a condenser, and the second heat exchanger 860 serves as an evaporator. A refrigerant pipe (not shown) is connected between the compressor 520, the first heat exchanger 510, and the second heat exchanger 860 to guide the flow of the refrigerant.

Therefore, when the gas refrigerant is compressed from the compressor 520 to a high temperature and high pressure and flows into the first heat exchanger 510, the refrigerant is condensed by heat exchange with outside air in the first heat exchanger 510. do.

The condensed refrigerant then expands while passing through an expansion valve (not shown) and enters the second heat exchanger 860. The refrigerant introduced into the second heat exchanger 860 evaporates by exchanging heat with external air. Therefore, the refrigerant is in a gaseous state, in which a liquid refrigerant also remains, and in fact, two-phase refrigerants are mixed.

After the refrigerant passes through the accumulator 530, the refrigerant is sent back to the compressor 520 to complete a cycle of the refrigerant.

Meanwhile, the air exchanges heat while passing through the first heat exchanger 510 and the second heat exchanger 860. This process will be described with reference to FIGS. 1, 2, and 14.

(Marked with '). Air flow at this time is basically generated by the lower fan 630. That is, when the lower motor 660 is driven by a power applied from the outside, the lower fan 630 connected to the shaft of the lower motor 660 rotates to generate air flow.

Therefore, the rear air is introduced through the lower grill 330 formed at the lower half of the rear frame 300. The air flowing forward through the lower grill 330 is changed in direction and flows to the left, and passes through the first heat exchanger 510.

The air passing through the second heat exchanger 860 rises in temperature. That is, since the second heat exchanger 860 serves as a condenser, air is received at a high temperature by receiving heat from a refrigerant flowing in the second heat exchanger 860.

The hot air passing through the second heat exchanger 860 passes through the orifice hole 612 and flows into the center portion of the lower fan 630. The air introduced into the center of the lower fan 630 flows radially by the rotation of the lower fan 630 and is guided by the exhaust guide 650 and discharged upward.

The hot air guided upward by the exhaust guide 650 is completely discharged to the outside of the building through the exhaust guide means 400.

'로 표시됨)을 살펴본다. 이때의 공기 유동은 기본적으로 상기 상부팬(840)에 의해 발생하게 된다. 즉, 외부로부터 인가되는 전원에 의해 상기 상부모터(820)가 구동하게 되면, 이러한 상부모터(820)의 축에 연결되어 있는 상기 상부팬(840)이 회전하면서 공기의 유동을 발생시키는 것이다.Next, the flow of air occurring on the endothermic side (upper portion of the main drain pan 700) (

Therefore, the air of the outside (indoor space) is introduced into the inside (front) through the suction grill 310 formed in the upper half of the rear frame 300. The air flowing through the suction grille 310 passes through the prefilter 320 and the deodorizing filter 322 in order, and foreign matters or odors in the air are removed in this process.

The air passing through the prefilter 320 and the deodorizing filter 322 passes through the second heat exchanger 860, and heat exchange occurs in this process. That is, since the second heat exchanger 860 acts as an evaporator, the air passing through the second heat exchanger 860 is cooled by heat exchange with a refrigerant.

The low-temperature air passing through the second heat exchanger 860 flows forward through the upper orifice hole 852 and flows into the center of the upper fan 840. The air introduced into the center of the upper fan 840 is radially discharged by the rotation of the upper fan 840, and the air is guided by the upper fan housing 810 to flow upward.

Air flowing upward by the upper fan housing 810 passes forward through the discharge guide 814 of the upper air guide 800 and passes through the discharge louver 110. The low temperature air passing through the discharge louver 110 discharges the discharge port 210 to the front to cool the indoor space.
