Embodiment Construction

[0031] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] The solution of this embodiment is mainly: based on including the most important eight parameters (human metabolic rate, external mechanical work of the human body, clothing thermal resistance, skin average temperature, air temperature, radiation temperature, relative humidity and air temperature) that affect the comfort of the human body. Flow rate) modified PMV control mechanism, the indoor environment parameters and human activities are sampled through the sensor, the crowd information is obtained through the camera, and the correlation coefficient is called, and the thermal comfort feeling of the corresponding crowd is obtained according to the PMV equation, and the air conditioner is controlled and driven The operating modes of compressors, outdoor motors, throttling components, etc., until PMV=0, to meet the thermal comfort needs o...

Abstract

The invention relates to an air conditioner and a control method thereof. The control method comprises the steps of collecting crowd information, season information and human body comfort level relevant parameters, computing control parameters of the air conditioner through a corrected PMV equation, controlling the air conditioner through the control parameters, so as to ensure that PMV is equal to 0, and human body optimum comfort state is achieved. Corrected parameters of the corrected PMV equation are measured through experiments in advance according to different regions and crowds, so that the air conditioner can be applied to different regions and crowds, can rapidly and accurately reach human body optimum comfort state of corresponding regions and crowds, and saves resource.

Description

technical field [0001] The invention belongs to the technical field of air conditioning control, and in particular relates to a method for automatically controlling an air conditioner according to human comfort and an air conditioner using the method. Background technique [0002] Traditional air conditioners generally only control the operation of the air conditioner by collecting the signal of the ambient temperature, and finally realize the control of the ambient temperature, or control the operation of the air conditioner by collecting the signals of the ambient temperature and relative humidity, and finally realize the ambient temperature and relative humidity. Humidity control. However, the above two methods only control the ambient temperature or relative humidity, while ignoring the influence of other factors. Once the wind speed, radiation temperature, clothing conditions, human activity, etc. change, the air conditioner will not be able to automatically operate the...
