Simulation method for optimizing structure of gas cooling garment

Abstract

The invention discloses a simulation method for optimizing a structure of a gas cooling garment. The method includes: establishing a model by utilizing three-dimensional software to form a micro-space; after the model is gridded, importing the gridded model into commercial software Fluent; setting boundary conditions, and inputting different labor intensity, ventilation quantity and environment temperature obtained through experiments; obtaining the numerical values of the environment temperature in the micro space, the wind speed in the micro space and the human body skin temperature under different labor intensity, ventilation quantity and environment temperature conditions are obtained by adopting a finite volume method and running software, comparing the values with experimental data,and when an error value is within an acceptable range, adjusting the structure of the gas cooling clothes model to obtain an optimal effect. By adopting the analogue simulation, the data in the microspace can be quickly and effectively detected, and the problems of high site requirement, high operation difficulty and time and labor waste caused by repeated operation of the existing method for acquiring the microclimate data through experiments are solved.

Description

【Technical field】 [0001] The present application relates to the technical field of cooling suits, in particular to a simulation method for optimizing the structure of gas cooling suits. 【Background technique】 [0002] The high-temperature working environment seriously affects the work efficiency of workers, and it is easy to cause the central nervous system of the person to be out of balance, make people tired and distracted, resulting in an increase in the accident rate. Wearing cooling clothing is one of the effective ways to resist high temperature. [0003] According to the cooling principle and cooling medium of the cooling suit, the cooling suit can be divided into three categories: gas cooling suit, liquid cooling suit and phase change cooling suit. Gas cooling suits mainly use natural air or compressed air or cold air generated by refrigeration equipment to cool the human body by evaporation and convective heat exchange. [0004] In the study of gas cooling clothin...
