Indoor heat environment comfort evaluation thermal manikin system and indoor heat environment comfort evaluation method

Abstract

The invention provides an indoor heat environment comfort evaluation thermal manikin system and an indoor heat environment comfort evaluation method. The indoor heat environment comfort evaluation thermal manikin system comprises a thermal manikin, a measuring and control system and an evaluation system. The thermal manikin has good joint motion capability, and has 16 independent measuring and heating control split regions; the split regions sufficiently consider the physiological structure characteristics of a human body and the heat exchange characteristics of the human body in the heat environment with the environment. The indoor heat environment comfort evaluation thermal manikin system has the advantages that the application range is wide; the system can be applied to heat environment in various fields such as civil use, military use, aero-space and navigation; the heat environment parameters can be directly and accurately measured; the heat environment comfort can be objectively evaluated; the test and the evaluation result is stable and accurate; the repeatability is high; the indoor heat environment comfort evaluation thermal manikin system conforms to the real human body heat state; the reasonableness and the reliability are realized.

Description

technical field [0001] The invention relates to an indoor thermal environment evaluation system, in particular to a thermal manikin system and an evaluation method for indoor thermal environment comfort evaluation. Background technique [0002] With the development of economy and technology and the continuous improvement of living standards, people have higher and higher requirements for thermal comfort of indoor environment. Therefore, various environmental control systems have been developed and applied, and the evaluation methods and technical capabilities of thermal environment comfort are becoming more and more important. more attention. [0003] Thermal comfort refers to people's subjective satisfaction with a hot and humid environment. It is usually evaluated by Predicted Mean Vote PMV and Predicted Percentage of Dissatisfied PPD. The main factors affecting thermal comfort are air temperature, air relative humidity, average radiant temperature, relative air velocity...

AI Technical Summary

Problems solved by technology

However, the existing thermal comfort detection and evaluation technology has problems such as poor mobility, low sensor accuracy, and poor consideration of environmental parameters; especially the PMV evaluation index used in the existing thermal comfort evaluation is based on The calculation of the temperature at a certain point or the average temperature of several points cannot truly reflect the surrounding environment of the human body. There is still a large e
