Air conditioner indoor unit and indoor air outlet control method for air conditioner

Abstract

The invention discloses an air conditioner indoor unit. The air conditioner indoor unit is provided with an air outlet, a shielding part, a controller and an infrared detector. The shielding part is used for shielding or opening the air outlet. When the air conditioner indoor unit is in a refrigerating running state, the controller is used for controlling the infrared detector to detect whether a human body exists in an air supply area of the air conditioner indoor unit or not; when the controller receives the signal that the infrared detector detects that the human body exists in the air supply area, the controller controls the air conditioner indoor unit to get into a preset running mode and controls part of the shielding part to shield the air outlet; and when the controller receives the signal that the infrared detector detects that no human body exists in the air supply area, the controller controls the air conditioner indoor unit to quit the preset running mode, and controls the shielding part to open the air outlet. The invention further discloses an air conditioner indoor air outlet control method. When a person is in the air supply area, the air outlet volume of the air conditioner indoor unit is automatically reduced so as to reduce the air speed of the environment, and the comfort degree of the environment is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner indoor unit and a method for controlling air outlet in the air conditioner room. Background technique [0002] The current air conditioner is used in summer, in order to quickly reduce the indoor temperature, the temperature of the air outlet of the air conditioner is generally 10°C to 15°C, and the temperature of the human body surface is generally 30°C to 33°C. "Cold wind" blowing directly on people will cause the sweat glands of the human body to close, affecting normal metabolism and secretion. Staying in the air-conditioned room for a long time and blowing "cold wind" will cause a kind of "air-conditioning disease". [0003] "GB_T18049-2000 Determination of PMV and PPD Indexes in Moderate Thermal Environments and Regulations on Thermal Comfort Conditions" proposes the vortex air flow intensity (DR), which is defined as the different degrees of loc...

Problems solved by technology

[0006] When the traditional air conditioner is in cooling operation, it usually operates at a constant wind speed to ensure the indoor ambient temperature. Since the ambient wind speed is not controlled, the environmental comfort is poor
