A method for controlling indoor thermal environment based on heart rate monitoring

Abstract

The invention discloses an indoor thermal environment control method based on heart rate monitoring, comprising: based on the collected indoor air temperature T a and indoor humidity RH to calculate indoor air moisture partial pressure Pa; based on resting heart rate HR o and the real-time average heart rate HR to calculate the user's real-time metabolic rate estimate M; based on the indoor air temperature T a , Indoor air moisture partial pressure Pa and the user's real-time metabolic rate estimated value M to calculate the user's thermal sensation index CPMV 0 ;Based on the user's thermal sensation index CPMV 0 Control the air conditioner. The present invention can more effectively carry out the operation and regulation of the air conditioner, and plays a great role in creating a dynamic indoor thermal environment conforming to nature and health. Compared with the traditional control model, the thermal sensation prediction value of the present invention is more accurate, and the comfort of the indoor thermal environment created by the control method is greatly improved.

Description

technical field [0001] The invention relates to the field of temperature regulation, in particular to an indoor thermal environment regulation method based on heart rate monitoring. Background technique [0002] Air-conditioning system energy consumption accounts for more than 30% of building energy consumption. Reasonable air-conditioning control methods play an important role in human comfort and building energy conservation. [0003] In the prior art, the intelligent air-conditioning control system usually adjusts the indoor temperature according to the PMV equation and the like. PMV (Predicted Mean Vote) is a comprehensive evaluation index based on the basic equation of human body heat balance and the level of subjective thermal sensation in psychophysiology, taking into account many factors related to human thermal comfort. The PMV index represents the feeling of most people in the same environment, so it can be used to evaluate whether a thermal environment is comfort...

AI Technical Summary

Problems solved by technology

The PMV index represents the feeling of most people in the same environment, so it can be used to evaluate whether a thermal environment is comfortable or not, but there are individual differences between people, so the PMV index may not represent the feeling of all individuals

In the PMV equation, the human body metabolic rate is difficult to monitor dynamically, so the existing intelligent air conditioning control system usually adopts a default value of about 1.2met, but this may be quite different from the actual situation of the indoor personnel, so it is difficult for users to requirements for comfort
