Air conditioner temperature adjusting method based on human finger tip skin temperature

Abstract

The invention discloses an air conditioner temperature adjusting method based on human finger tip skin temperature, which comprises the following steps: S1, measuring the finger tip skin temperature of a human body to obtain finger tip temperature data; s2, calculating through the fingertip temperature data to obtain a thermal sensation evaluation value; s3, the thermal feeling evaluation value is judged, and the set temperature of the air conditioner is adjusted according to the judgment result; s4, after a certain period of time, the fingertip skin temperature is measured again, and if the difference value between the current fingertip temperature value and the last measured value is larger than 0.5 DEG C, the thermal feeling evaluation value is calculated again according to the current fingertip temperature value, and the air conditioner set temperature is adjusted; if the difference value between the current fingertip temperature value and the last measured value is not larger than 0.5 DEG C, the set temperature of the air conditioner is kept unchanged; and S5, the step S4 is repeated until the set temperature of the air conditioner does not change any more or the air conditioner is used.

Description

technical field [0001] The invention relates to the field of air conditioning temperature regulation, in particular to an air conditioning temperature regulation method based on the skin temperature of human fingertips. Background technique [0002] At present, the adjustment of air-conditioning temperature is mainly controlled manually, while automatic adjustment of air-conditioning temperature is a necessary trend in the development of air-conditioning, and automatic adjustment of air-conditioning temperature mainly relies on environmental thermal comfort evaluation as the basis for adjustment; Average thermal sensation index (PMV) and predicted dissatisfaction rate (PPD). This method predicts thermal comfort by calculating environmental parameters and human activity, clothing status, and estimating the thermal balance of the whole body. There are environmental parameters and human status in use. Problems such as difficulty in data collection and high operational complexit...

Problems solved by technology

[0002] At present, the adjustment of the air conditioner temperature is mainly controlled manually, and the automatic adjustment of the air conditioner temperature is a necessary trend in the development of the air conditioner, and the automatic adjustment of the air conditioner temperature mainly relies on the environmental thermal comfort evaluation as the adjustment basis; the existing environmental thermal comfort evaluation generally adopts the estimated Average Thermal Sensation Index (PMV) and Predicted Dissatisfaction Rate (PPD), this method is to predict thermal comfort by calculating environmental parameters, human activities, and clothing status, estimating the thermal balance of the whole body, and there are environmental parameters and human status in use For problems such as difficult data collection and high operational complexity, another method is to use the subject’s subjective scale. This method requires the subject to fill in the questionnaire, which is greatly affected by the subject’s subjective factors and cannot be applied. In the automatic adjustment of air-conditioning temperature; therefore, it is necessary to study a method that is easy to operate and can realize automatic adjustment of air-conditioning temperature to solve the above problems
