In the air conditioner 100 of the present invention, the metal filter 34 is provided with a heating device for heating the metal filter 34.
Fig. 2 is a diagram showing a heating device for the metal strainer 34 according to the first embodiment of the present invention.
A branch pipe 33 is provided around the metal strainer 34. As shown in fig. 2, the branch pipe 33 closely surrounds the outer frame 341 of the metal filter. However, the branch pipe 33 may be closely attached to only a part of the bead frame 341, for example, to the upper side or the lower side of the bead frame 341. The branch pipe 33 may be installed in such a manner that the branch pipe 33 and the metal mesh 34 can conduct heat efficiently.
The branch pipe 33 is connected to the heat exchanger 2 via the flow dividing device 6. Specifically, the branch pipe 33 may be connected to an inlet end, an outlet end, or an intermediate stage of the heat exchanger 2 via the flow dividing device 6. The high-temperature refrigerant flowing into the heat exchanger 2 or a part of the high-temperature refrigerant flowing through the heat exchanger 2 flows into the branch pipe 33. Since the branch pipe 33 is in close contact with the metal mesh outer frame 341, when the high-temperature refrigerant flows through the branch pipe 33, heat is efficiently conducted to the metal mesh 34, and the metal mesh 34 can be heated. The high-temperature refrigerant flowing through branch pipe 33 heats metal filter 34, and then returns to heat exchanger 2.
In the present invention, the flow rate of the high-temperature refrigerant flowing into the branch pipe 33 is controlled by using the flow dividing device 6. Fig. 3 is a diagram showing a refrigerant flow divider 6 according to a first embodiment of the present invention.
As shown in fig. 3, the flow dividing device 6 is disposed between the heat exchanger 2 and the inlet end of the branch pipe 33. Although the flow dividing means 6 may also be arranged between the heat exchanger 2 and the outlet end of the branch pipe 33.

One end of the second connection pipe 64 is connected to the electronic expansion valve main body 61, and the other end is connected to the branch pipe 33.
The first connection pipe 63 and the second connection pipe 64 may be copper pipes, aluminum pipes, alloy pipes, or the like.
When the control coil 62 is energized, the opening degree of the electronic expansion valve main body 61 is controlled by controlling the current or voltage of the control coil 62, thereby controlling the flow rate of the high-temperature refrigerant flowing into the branch pipe 33. Thus, the purpose of controlling the temperature of the metal filter 34 is achieved.

A central controller (not shown) of the air conditioner 100 analyzes the detected temperature and humidity information based on the information, controls the operating state of the flow divider 6, and adjusts the temperature of the metal mesh 34.
Specifically, first, the ambient room temperature sensor 35 and the ambient humidity sensor 36 transmit the detected ambient temperature and humidity information to the central controller, from which the central controller calculates the dew point temperature t1 of the metal mesh, and the mesh temperature sensor 344 transmits the detected temperature t2 of the metal mesh to the central controller. Then, the central controller analyzes the dew point temperature t1 of the metal filter screen and the temperature t2 of the metal filter screen, and compares the dew point temperature t1 of the metal filter screen with the temperature t2 of the metal filter screen. When it is determined that the temperature t2 of the metal mesh is lower than the dew point temperature t1, the central controller controls the flow dividing device 6 to increase the opening degree of the electronic expansion valve so that the flow rate of the high-temperature refrigerant entering the branch pipe 33 increases, and when it is determined that the temperature t2 of the metal mesh is higher than the safe temperature (the dew point safe temperature is, for example, the dew point temperature + a certain fixed correction temperature) of the dew point temperature of the metal mesh, the central controller controls the flow dividing device 6 to decrease the opening degree of the electronic expansion valve so that the flow rate of the high-temperature refrigerant entering the branch pipe 33 decreases, and when it is determined that the temperature of the metal mesh is a proper temperature (for example, the dew point temperature — the dew point safe temperature), the central controller controls the flow dividing device 6 to maintain the opening degree of the electronic expansion valve so that the.
Further, the flow rate of the high-temperature refrigerant entering the branch pipe 33 may be controlled by sending only the ambient temperature detected by the ambient room temperature sensor 35 and the filter screen temperature sensor 344 and the temperature information of the metal filter screen to the central controller, analyzing the information by the central controller, and controlling the flow dividing device 6 based on the comparison result between the ambient temperature and the temperature of the metal filter screen.
Accordingly, the temperature of metal strainer 34 can be adjusted to a desired temperature by controlling the flow rate of the high-temperature refrigerant flowing into branch pipe 33. For example, the temperature of the metal filter 34, that is, the temperature of the air inlet area, is adjusted to be higher than the temperature detected by the ambient room temperature sensor, so that the high-humidity air sucked into the air inlet 3 does not condense on the air inlet 3 due to cooling.
The temperature of metal strainer 34 can be controlled more precisely using the temperature and humidity information than using only the temperature information.
In the present embodiment, the refrigerant of the air conditioner 100 itself is used, and there is no need to introduce an additional heating substance or structure, which is advantageous for downsizing the air conditioner 100.
