Problems solved by technology

However, it is not appropriate to adjust the wind speed in the air-conditioning system, and when the existing intelligent air-conditioning judges the movement state of the human body, the samples used are too limited, and the method of using the corrected skin temperature in the PMV formula is unreasonable
The current air conditioner only controls the temperature and wind speed, ignoring the influence of the movement state of people in different zones and the thermal resistance of clothing on the body's body temperature

Embodiment Construction

[0024] The embodiment of the present invention provides an air-conditioning control method, which deduces the most comfortable indoor temperature t according to the PMV formula a , so as to control the temperature of the air conditioner, including:

[0025] According to the PMV formula PMV=F(M,W,P a ,t a ,f cl ,t cl ,t r , h c )

[0026] PMV=(0.303exp -0.036M +0.0275)*{M-W-3.05[5.733-0.007(M-W)-P a ]}

Abstract

The invention discloses an air conditioner control method adaptive to temperature change. The most comfortable indoor temperature is calculated through a PMV formula which contains the parameters suchas the human body metabolism amount, the mechanical work made by a human body, the water vapor partial pressure in air, the human body wearing area, the indoor radiation temperature, the human body surface average temperature and the flow heat exchange coefficient. The method has the technical effects that the human body optimum temperature PMV formula is used for reversely deducing the set indoor temperature, the specified temperature signal are transmitted to an air conditioner, the traditional mode that a user actively sets the temperature of the air conditioner is replaced, the intelligent degree of a product is improved, and the user experience is optimized. On the energy consumption, the thermal resistance of a human body garment is estimated through the outdoor temperature obtainedby the outdoor temperature sensor, and the energy is saved.

Description

technical field [0001] The invention relates to an air conditioning control method adaptive to air temperature changes. Background technique [0002] The current air conditioners generally require the user to actively set the indoor temperature, and adjust the temperature by comparing it with the indoor temperature detected by the temperature sensor, which is inconvenient to use. Current smart air conditioners generally improve human comfort by adjusting the wind speed. However, it is not appropriate to adjust the wind speed in the air-conditioning system, and when the existing intelligent air-conditioning judges the movement state of the human body, the samples used are too limited, and the method of using the corrected skin temperature in the PMV formula is unreasonable. The current air conditioner only controls the temperature and wind speed, ignoring the influence of the movement status of people in different zones and the thermal resistance of clothing on the body's bo...
