Hereinafter, the operation of the air conditioner according to the present invention will be described.

First, the flow of refrigerant and air in the air conditioner according to the present invention will be described.

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.

At this time, 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 and the first heat exchanger 510 and the second heat exchanger 860 to guide the flow of the refrigerant.

Accordingly, when the gas refrigerant from the compressor 520 is compressed and flows into the first heat exchanger 510 in a state of high temperature and high pressure, the refrigerant is condensed by heat exchange with the 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 flowing into the second heat exchanger 860 undergoes heat exchange with the outside air and evaporates. Therefore, the refrigerant becomes a gaseous state, and at this time also the refrigerant in a liquid state remains, and actually two-phase refrigerant is 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 18.

'로 표시됨)을 살펴본다. 이때의 공기 유동은 기본적으로 상기 하부팬(630)에 의해 발생하게 된다. 즉, 외부로부터 인가되는 전원에 의해 상기 하부모터(660)가 구동하게 되면, 이러한 하부모터(660)의 축에 연결되어 있는 상기 하부팬(630)이 회전하면서 공기의 유동을 발생시키는 것이다.First, the air flow (in the figure, '

'). At this time, the air flow is basically generated by the lower fan 630. That is, when the lower motor 660 is driven by an external power source, the lower fan 630 connected to the shaft of the lower motor 660 rotates to generate air flow.

Therefore, the rear air flows 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 diverted to flow to the left side and passes through the first heat exchanger 510.

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

The hot air passing through the second heat exchanger 860 passes through the lower orifice hole 602 and flows into the center of the lower fan 630. The air flowing into the central portion 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 상부모 터(820)가 구동하게 되면, 이러한 상부모터(820)의 축에 연결되어 있는 상기 상부팬(840)이 회전하면서 공기의 유동을 발생시키는 것이다.Next, the flow of the air that occurs at the heat absorption side (the upper portion of the main drain pan)

'). At this time, the air flow is basically generated by the upper fan 840. That is, when the upper motor 820 is driven by a power applied from the outside, the upper fan 840 connected to the shaft of the upper motor 820 rotates to generate air flow.

Accordingly, the outside (indoor space) air flows inward (forward) through the suction grille 310 formed on the upper half of the rear frame 300. The air introduced through the suction grille 310 passes through the pre-filter 320 and the deodorizing filter 322 in order to remove foreign substances and odors in the air.

The air having passed through the pre-filter 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 functions as an evaporator, air passing through the second heat exchanger 860 is cooled by heat exchange with the refrigerant.

The low-temperature air having passed 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 is discharged to the front of the discharge port 210 to cool the indoor space. Meanwhile, air passing through the discharge louver 110 is also diverted by a plurality of ribs formed in the discharge louver 110.

Next, a process of fastening the suction grill 310 to the rear frame 300 will be described schematically.

First, the suction grille 310 is brought close to the rear of the rear frame 300. Then, the grill fastening protrusion 317 formed at the lower end of the suction grill 310 is inserted into the grill protrusion insertion hole 354.

After the grille fastening protrusion 317 is inserted into the grille projection insertion hole 354, the upper end of the suction grille 310 is pushed forward. Then, a grill fastening hook 316 formed on the upper end of the suction grill 310 is inserted into the grill hook fastening hole 374. When the grill fastening hook 316 is inserted into the grill hook fastening hole 374, the grill fastening hook 316 is prevented from being separated by the fastening portion 316 'formed at the front end of the grill fastening hook 316.

In this manner, the suction grill 310 is mounted on the rear frame 300. In order to separate the suction grille 310 mounted by the above-described process, the suction grille 310 is reversed according to the above-described installation.

That is, in order to separate the suction grille 310, the removal rib 315 is pulled forward while being held by a hand. As a result, the grill fastening hook 316 flows to the left and right due to its own elasticity, so that the retaining portion 316 'of the grill fastening hook 316 moves backward through the grill hook fastening hole 374 .

Then, the suction grille 310 is lifted upward. The grill fastening protrusion 317 of the suction grill 310 is separated from the grill projection insertion hole 354 and is released upward. By this process, the suction grill 310 is completely separated.

On the other hand, in order to lift the air conditioner as described above, the user must raise his / her hand while holding the hand on the pair of handles 340. At this time, it is preferable to stand up in front of the above-mentioned air conditioner. That is, since the inner space of the handle 340 is gradually widened toward the rear side, it is preferable that the human perception (second finger) is positioned at the inner rear end of the handle 340.

In order to assemble the knob 340 to the knob hole 342, it is possible to apply the force by pressing the knob 340 on both sides. That is, since the fixing rib 348 of the handle 340 is inclined at one side to form the guide surface 348 '', when the handle 340 is pushed into the handle hole 342, And this guide surface 348 " slides in contact with the rim of the handle hole 342.
