Normal-low pressure high-low temperature human body thermal comfort experiment environment cabin

Abstract

The invention, which belongs to the field of building heating-ventilation air conditioners, relates to a normal-low-pressure high-low-temperature human body thermal comfort experiment environment cabin comprising an environment cabin body, a pressure control system, a temperature and humidity control system, a fresh air control system, an oxygen concentration control system, an illumination control system, an environment monitoring and controlling system and a human body physiological parameter measuring system. The pressure control system, the temperature and humidity control system, the fresh air control system, and the oxygen concentration control system are arranged at the outer side of the environment cabin body; and the illumination control system, the environment monitoring and controlling system and the human body physiological parameter measuring system are arranged in the environment cabin body. The pressure control system is mainly formed by sequentially connecting a vacuumpump and a vacuum tank with the environment cabin body. The temperature and humidity control system is mainly formed by sequentially connecting a direct evaporation surface cooling section, an electric heating section, a fan section and a humidifying section with the environment cabin body. The fresh air control system is mainly formed by sequentially connecting a filter, a dehumidifier, a gas-gasheat exchanger and a silencer with the environment cabin body.

Description

technical field [0001] The invention relates to a human body thermal comfort experimental environment construction and measurement device, in particular to a normal low pressure high and low temperature human thermal comfort experimental environment cabin, which can simulate normal low pressure, high and low temperature environments, and provides a basis for human thermal comfort research in different environments. The experimental conditions belong to the field of building HVAC. Background technique [0002] Whether it is a natural environment or an artificial environment, it has a great impact on the human body and equipment. For the human body, suitable environmental conditions can ensure its life safety, improve comfort and work ability. In order to quantify the impact of various environmental factors on human thermal comfort and propose countermeasures, experiments under different environmental conditions are required. [0003] Thermal comfort is the thinking activity...
