Description

technical field [0001] The invention relates to the technical field of indoor air quality control, in particular to an air-conditioning control system and control method based on the detection of human thermal response biochemical indicators. Background technique [0002] With the development of my country's economy and air-conditioning technology, air-conditioning systems are widely used in building interiors. In the prior art, the thermal comfort evaluation of the human body in an indoor environment with an air-conditioning system is generally predicted by skin temperature. Perceive changes in ambient temperature and body temperature, and then feed back temperature signals to the body temperature regulation center for processing, and then send corresponding signals through the hypothalamus to regulate body temperature. Therefore, the skin temperature can change linearly with the ambient temperature within a certain temperature range, reflecting the change of heat exchange b...

Problems solved by technology

However, the current use of temperature sensors to measure human skin temperature lacks a deep-seated mechanism explanation, and the application of temperature sensors has certain limitations. Affects the test accuracy of the temperature sensor, resulting in the inability of the skin temperature obtained by the test to accurately represent or evaluate the thermal comfort of the human body; in addition, due to the impact of the human body's cold war in a cold environment, there are also deviations in predicting the thermal comfort of personnel by skin temperature

Therefore, the use of physiological indicators such as skin temperature to predict human thermal comfort can only be applied within a certain temperature range, and the internal mechanism that causes skin temperature changes is unknown, so it cannot be used as an effective indicator to characterize human thermal comfort in a wide temperature range
