Air conditioning indoor unit and control method thereof

Abstract

The invention relates to the technical field of air conditioning, in particular to an air conditioning indoor unit and a control method thereof and aims to solve the problem of high noise of an existing air conditioner when the supplied air volume is high. The air conditioning indoor unit comprises an indoor unit body, and a heat exchanger and a blower are arranged in the indoor unit body; the airconditioning indoor unit further comprises an air supplement module; the air supplement module comprises a shell body, an air inlet pipe communicating with the outdoor is arranged on the shell body,and an induced draft fan and a connecting pipe are arranged in the shell body; the first end of the connecting pipe is connected with the air outlet of the induced draft fan, and the second end of theconnecting pipe extends to the air inlet side of the heat exchanger; the air supplement module is driven by the induced draft fan to introduce the outdoor fresh air into the shell body and exhaust the outdoor fresh air into the air inlet side of the heat exchanger after the outdoor fresh air flows through the induced draft fan and the connecting pipe; and a drainage plate is arranged on the connecting pipe and introduces the nearby air into the connecting pipe when the induced draft fan works. By arranging the air supplement module, the noise of the air conditioning indoor unit during runningof the air conditioning indoor unit can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioner indoor unit and a control method thereof. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the quality of life, and this requirement is particularly evident in household appliances. Taking air conditioners as an example, when the indoor and outdoor temperature difference is large, in order to meet the needs of users for rapid cooling / heating after entering the room from the outside, the existing air conditioners usually have a rapid cooling / heating function. When functioning, the compressor of the air conditioner works at a higher frequency to quickly increase the cooling capacity / heating capacity, and the indoor unit of the air conditioner runs at a high speed and a large air volume to send the heat-exchanged cold air / hot air back to the room, thereby realizing indoor cooling.
