For a long time, the comfort evaluation of automobile air-conditioning mainly draws on the evaluation method of building air-conditioning comfort, and there is no recognized comfort evaluation system of automobile air-conditioning. In addition, when evaluating the comfort of automotive air conditioners (HVAC) at home and abroad, most of the evaluation indicators of human thermal comfort are applied to CFD simulation calculations. However, this method involves a large number of numerical calculations, and the accuracy of the result is not high, and the method cannot accurately assess the physical state of the tested person, and cannot achieve stable controllability.
Technical realization elements:
The thermal comfort test dummy for automobile air-conditioning can simultaneously measure the thermal conditions of various parts of the human body in the external environment, thereby accurately assessing the environmental factors in the car interior, and effectively avoiding errors caused by individual differences in the human body.
Simultaneous detection of wind speed, temperature, humidity, and thermal radiation
Intelligent software online system real-time monitoring, support WiFi and wired transmission;
The interior of the human body model is hollow, and all joints are connected by metal parts, and the angle can be set arbitrarily. The installation and disassembly of the sensor is simple and convenient.
It is suitable for the comfort test of the car interior and indoor air conditioning system. The system makes a comprehensive evaluation of the comfort of the car interior and specific space by measuring wind speed, temperature, humidity and heat radiation at the same time.
Overcome the shortcomings of the existing automotive air conditioning (HVAC) comfort evaluation methods, and can simultaneously measure the thermal conditions of various parts of the human body in the external environment, thereby accurately assessing the car interior environmental factors, and effectively avoiding individual differences due to the human body The resulting error.
