Problems solved by technology

[0019] First, when too much foreign matter accumulates on the above-mentioned filter net and causes the above-mentioned filter net to be blocked, the flow cross-sectional area of ​​Freon will become smaller, resulting in greater flow resistance
Therefore, Freon cannot circulate smoothly
This will reduce the cooling performance of the air conditioner, and may also cause the suction part of the compressor to freeze
These are the problem points that cause the efficiency of the air conditioner to decrease
[0020] Second, when too much foreign matter accumulates on the above-mentioned filter screen and blocks a considerable part of the filter screen, the excessive flow pressure may damage the above-mentioned filter screen
Therefore, not only the flow resistance of Freon is increased, but also the load acting on the filter is increased.

Embodiment Construction

[0039] Below, the embodiment of the Freon filter device of the air conditioner in the present invention will be described in detail in conjunction with the accompanying drawings.

[0040] For the convenience of description, the same structural parts as those in the prior art are given the same names and symbols, and detailed descriptions thereof are omitted here.

[0041] The embodiment of the Freon filter device of the air conditioner in the present invention will be described below with reference to FIGS. 2 to 4 .

[0042] In the following description, in the flow pipe where freon flows, the front of the direction in which freon flows is called upflow, and the rear of the direction in which freon flows is called downflow.

[0043] As shown in FIG. 2 , in the above-mentioned channel tube 110 , the curved part forms a curved tube part 120 .

[0044] The bending angle of the curved pipe portion 120 is preferably a right angle, but it is not necessarily limited to a right angle...

Abstract

It relates to a Freon filtering device of an air conditioner. It mainly comprises the curved tube formed by the bending of the flow channel, and abnormal material filtering net on the outside wall of the curved channel. It features in the smaller diameter of the down flow net holes than that of the up flow net holes. It will not reduce flowing cross section of running Freon when abnormal material accumulated on the filtering net, without increasing flowing resistance of the Freon.

Description

technical field [0001] The present invention relates to an air conditioner, and more specifically relates to a Freon filter device for an air conditioner capable of filtering foreign substances in Freon of the air conditioner. Background technique [0002] Generally speaking, an air conditioner is a device installed in a living room, a restaurant, or an office, and performs cooling or heating operations on the interior space thereof. [0003] The air conditioner is composed of an indoor unit and an outdoor unit, and further includes a flow path for circulating freon between the indoor unit and the outdoor unit, a compressor for compressing the freon, and the like. [0004] When the freon circulates between the indoor unit and the outdoor unit, the temperature of the indoor air is adjusted through the process of heat absorption and heat release caused by entropy change. [0005] That is, when the air conditioner is in the cooling operation mode, the Freon evaporates in the i...
