Air conditioner and control method thereof

Abstract

The invention belongs to the field of air conditioners, and particularly relates to an air conditioner and a control method thereof. The air conditioner comprises an indoor unit, and the indoor unit comprises a machine body and a fresh air device; the machine body is provided with an air inlet and an air outlet which communicate with each other and form an air flow path; the fresh air device comprises a fresh air support, and the fresh air support is fixed on the machine body and provided with a first fresh air outlet; the fresh air device further comprises a first fresh air channel and a second fresh air channel which are arranged in the fresh air support and can be selectively opened and closed; first free ends of the first fresh air channel and the second fresh air channel are respectively provided with a first fresh air inlet and a second fresh air inlet which are used for communicating with the outdoor space; the first fresh air inlet, the first fresh air channel, the fresh air support and the first fresh air outlet form a first fresh air flow path; and the second fresh air inlet, the second fresh air channel and the air outlet form a second fresh air flow path. The air conditioner and the control method thereof have the advantages that a large quantity of fresh air can be obtained, and the fresh air quantity can be adjusted.

Description

technical field [0001] The field of the invention belongs to the field of air conditioners, and in particular relates to an air conditioner and a control method thereof. Background technique [0002] Existing air conditioners include indoor units and outdoor units such as wall-mounted or cabinet units. Existing air conditioners all use heat exchange methods to blow cold or hot air to the outside through the air outlet to provide cooling or heat to the room. The old air is circulated for refrigeration or heating. After a long period of air circulation, the indoor air will gradually become turbid because it cannot be replaced, and the concentration of carbon dioxide will continue to rise, which is very unfavorable to people's physical and mental health. [0003] With the development of technology, a new air conditioner for fresh air has also appeared on the market, which can provide fresh air for the room, thereby avoiding the above-mentioned repeated cooling or heating of the...

Problems solved by technology

[0002] Existing air conditioners include indoor units and outdoor units such as wall-mounted or cabinet units. Existing air conditioners all use heat exchange methods to blow cold or hot air to the outside through the air outlet to provide cooling or heat to the room. The old air is circulated for refrigeration or heating. After a long period of air circulation, the indoor air will gradually become cloudy because it cannot be replaced, and the concentration of carbon dioxide will continue to rise, which is very unfavorable to people's physical and mental health.

[0003] With the development of technology, a new air conditioner for fresh air has also appeared on the market, which can provide fresh air for the room, thereby avoiding the above-mentioned repeated cooling or heating of the old air. However, the current fresh air air conditioner has The problem of small fresh air volume, high cost, and unadjustable fresh air volume
