Self-balancing type body warming dummy and using method thereof

Abstract

The invention discloses a self-balancing type body-warming dummy and a using method thereof, which simulate a sitting human body and arrange an internal heating system and an aerodynamic system in thebody-warming dummy to realize self heat balance, and the body-warming dummy provided by the invention can realize constant power 95W and a human body surface constant temperature function. The constant temperature precision value of the warm dummy depends on the temperature value of an air-conditioned room where the dummy is located and the wind field condition around the dummy, and the maximum precision is + / -1.5 DEG C. Most importantly, the dummy is a heat self-balancing dummy, and the purposes of constant power and constant temperature can be achieved without an external complex control system.

Description

technical field [0001] The invention belongs to the technical field of thermal manikin, in particular to a self-balancing thermal manikin and a use method thereof. Background technique [0002] Occupants are one of the main heat sources and pollution sources in buildings. Due to the development of building energy conservation and low-energy office equipment, the proportion of its influence in the total heat source and total pollution source of buildings will increase day by day. The convection generated by the human body has an important impact on the distribution of indoor air, especially the thermal plume generated during the sitting state. It is of great significance to study the performance of ventilation and air conditioning systems, indoor airflow organization, indoor pollutant distribution and infectious disease pathogen distribution. However, using real people to do experiments to explore this mechanism has three limitations: [0003] (1) It will cost a lot of manp...

AI Technical Summary

Problems solved by technology

[0003] (1) It will cost a lot of manpower and financial resources, and the cost is high

[0004] (2) When studying the thermal plume above the human body, it is difficult to use the integral method for data analysis, (due to the unstable behavior of the real person and the sensitive characteristics of the thermal plume)

[0005] (3) When doing research on the transmission of pollutants and infectious pathogens, it is dangerous for real people

However, such geometric models have shown several limitations during experiments:

However, the simple geometric structure lacks a leg model and cannot simulate the local airflow organization around the human body

[0012] (4) Relevant literature shows that the thermal plume generated by the anthropomorphic model is closely related to the arrangement of the built-in heat source. However, there is no uniform standard for the heating equipment arranged in the simple geometric structure and the location of the heating equipment, which will make the experimental results inconsistent. Verification and large error in each experiment

[0013] (5) The simple anthropomorphic geometric structure used in the experiment is mostly made of simple cardboard, the simulation accuracy is not high, and it is not suitable for repeated use

[0016] (1) The software simulation results are not accurate and can only analyze the general situation

Especially for the complex geometry of the human body, the simulation results will not be very accurate in the area close to the body

[0017] (2) Software simulation requires more complex computing power and longer computing time, and the computing cycle is very long
