Human body respiratory performance parameter detection apparatus

Abstract

The invention provides a human body respiratory performance parameter detection apparatus comprising an inspiration pipeline, an expiration pipeline, flow meters, a blower, low-temperature sampling bottles, oxygen / carbon dioxide / ammonia gas probes, particle counters, data recorders, and a gas and liquid phase chromatography analysis instrument. According to the invention, the inspiration pipelineand the expiration pipeline are separated, inspiration expiration flow rates of a human body, respiratory flow temperatures and relative humidities, oxygen concentrations, pollutant gas concentrations, and particle concentrations are respectively measured, such that human body respiratory basic performance parameters are obtained. Therefore, a scientific basis is provided for the optimization of air conditioning system novel air delivery and the design of indoor air distribution. Also, a solution is provided for realizing an aim that the air conditioning system is used for serving people's health. Therefore, a purpose of a healthy, energy-saving and sustainable-developing heating, ventilation, and air conditioning system can be achieved.

Description

technical field [0001] The invention belongs to the technical fields of HVAC, indoor air quality and air cleaning, and relates to a detection method and a detection system for human respiratory performance parameters. Background technique [0002] With the continuous deepening of the concept of sustainable development of buildings, building energy conservation and ensuring the health of indoor occupants have become two major issues that need to be faced in the field of air conditioning. At present, air-conditioning energy consumption accounts for an important part of my country's building energy consumption, and fresh air energy consumption is the top priority. [0003] At present, HVAC designers in my country often refer to foreign standards when determining the fresh air volume, lacking in-depth research on national conditions and Chinese characteristics. For the sake of safety, a higher fresh air volume is often selected, which makes the building energy consumption becom...

AI Technical Summary

Problems solved by technology

[0011] From the above introduction, it can be seen that there is no comprehensive detection method and detection device specifically for the indoor environment to study the oxygen demand of human respiration, the pollutants and moisture produced by human respiration, and the dust accumulation characteristics of human lungs, and there is no It can realize separate sampling and switching of inspiratory and exhalation pipelines. In addition to simple temperature and humidity detection, there is no device that considers the sampling of various low-concentration and low-volatile pollutants in human breath.
