Air filter device for air conditioner in machine room and air conditioner

Abstract

The invention discloses an air filter device for an air conditioner in a machine room and the air conditioner, and relates to the field of air conditioner equipment. The air filter device for the airconditioner in the machine room comprises an outer frame. A through hole is formed in the middle of the outer frame. A nylon filter screen is arranged on the outer frame and covers the through hole. Amounting groove is arranged in the outer frame, an opening of the mounting groove is arranged on the side face of the outer frame, and a low-penetration filter plate is arranged in the mounting groove and is parallel to the nylon filter screen. The air conditioner comprises a heat exchanger, the air filter device for the air conditioner in the machine room is arranged on one side of the heat exchanger, and a fan is arranged on the other side of the heat exchanger. According to the air filter device for the air conditioner in the machine room, the detachable low-penetration filter plate is arranged on the outer frame, different filter grades can be selected for air of different dust contents, the optimal filter effect is achieved when the dust content in the air is high, and when the dustcontent in the air is low, the filter effect is guaranteed, and the optimal ventilation effect is achieved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air filter device and an air conditioner for an air conditioner in a computer room. Background technique [0002] The use of air conditioners has become more and more common. Air conditioners are required in various places. The use environment in different places is different, and even the use environment in some places of use will change, especially for houses. Wait for the dust content to be extremely high, and after a period of time, the content of dust and other dust in the air reaches a normal level. Existing air conditioners generally realize the filtering of air through two different grades of filter screens. One is a high-permeability filter frame with nylon mesh, which has a good ventilation effect but the dust-proof level can only meet the air with normal dust content; the other is a G4-level primary filter, which is made of non-woven fabrics, glass fibers, etc. The...

AI Technical Summary

Problems solved by technology

One is a high-permeability filter frame with nylon mesh, which has a good ventilation effect but the dust-proof level can only meet the air with normal dust content; the other is a G4-level primary filter, which is made of non-woven fabrics, glass fibers, etc. Filter material, wedge-shaped folding shape to increase the filter area, good dust-proof effect but poor ventilation, which increases the load on the fan, and is not suitable for long-term use after the dust content in the house air decreases

Neither of these two filter devices can adjust the filter level to adapt to the change of dust content according to the change of house air dust content
