Thermal comfort instrument and evaluation method based on Chinese thermal characteristics

Abstract

The invention provides a heat comfortable instrument based on heat characteristics of Chinese people and belongs to the field of building indoor environment. The heat comfortable instrument comprises a measuring device for indoor environment parameters and a 8051 single-chip microcomputer used as a calculator and a controller of the system. Environment parameters, personnel parameters, a multi-node Chinese people heat adjusting model and a heat sensing model are set in a program in advance, and a self-adaption method is simultaneously added into the program, so that the heat comfortable instrument is not only suitable for the Chinese people, and the prediction method can be corrected to a certain degree according to different people and different social customs, so that the heat comfortable instrument can be used for predicting heat comfort and heat senses under different conditions. The heat comfortable instrument is capable of accurately predicting the heat comfort states of the Chinese people, a valuable reference is provided for civil indoor environment evaluation and design, and an air conditioner strategy based on the Chinese people heat sense prediction is capable of improving the energy saving effect of an air condition on the premise that the heat comfort of the human body is met.

Description

technical field [0001] The invention relates to a thermal comfort instrument for evaluating the thermal comfort of a human body in an indoor thermal environment, in particular to a thermal comfort instrument for predicting the thermal comfort of Chinese people based on the thermal characteristics of Chinese people, belonging to the field of building indoor environment. Background technique [0002] Accurately predicting the thermal comfort state of the human body is an important method to evaluate whether an indoor thermal environment is comfortable, and the thermal comfort state is generally expressed by the thermal sensation of the indoor environment. The thermal sensation can be divided into seven levels from cold to hot. They are cold, cool, slightly cool, neutral, slightly warm, warm, and hot, respectively, and their corresponding scores are -3 to 3. The more commonly used thermal comfort prediction method in the world is the PMV-PPD model proposed by Fanger in 1982, wh...

Problems solved by technology

Therefore, ethnic differences between China and the West have a great impact on thermal comfort, but these differences have not been considered in existing multi-node models

[0003] On the other hand, in the prior art, the application number is 01132267.5, and the name is an instrument for measuring the indoor comfort level considering the metabolic rate of the human body and the thermal resistance of clothing. , humidity, air flow velocity and average heat radiation temperature) and the amount of human activity and clothing thermal resistance to evaluate the thermal comfort of indoor environment, however, although this patent considers the impact of different activity levels and clothing thermal resistance on human body heat However, its basic principle is still based on the PMV-PPD model proposed by Fanger. Therefore, the thermal comfort instrument is not enough to predict the thermal comfort state in some complex indoor environments, such as dynamic environments and uneven indoor environments. precise

Therefore, in summary, there is no thermal comfort instrument that considers the thermal physiological and thermal psychological characteristics of Chinese people.
