夏季降温过程中车内热环境及热舒适评价

本文主要通过夏季降温性能实验对车内的热环境进行测试,对汽车空调的降温性能以及乘客的热舒适进行评价。首先通过采集车内的环境参数分析车内热环境特点,然后通过环境参数计算三种热舒适评价指标,对车内乘客的热舒适进行评价并与乘客的主观评价进行对比,结果发现等效温度在瞬态工况下与乘客主观评价的投票值最接近,可以作为降温性能实验中衡量热舒适的评价指标。

Evaluation of Thermal Environment and Thermal Comfort during Summer Cooling

This paper mainly tests the thermal environment inside the vehicle through the summer cooling performance test,and evaluates the cooling performance of the vehicle air conditioner and the passenger’s thermal comfort.Firstly,the characteristics of the thermal environment in the car are analyzed by collecting environmental parameters inside the vehicle.Then,using the exponential function to fit the air temperature inside the vehicle,and then three thermal comfort evaluation indexes are calculated through the environmental parameters.The thermal comfort of the passengers inside the vehicle is evaluated and compared with the subjective evaluation of the passengers.It is found that the equivalent temperature is closest to the voting value of the subjective evaluation of the passenger under transient conditions.It can be used as an evaluation index for evaluating thermal comfort in cooling performance experiments.
