Abstract:
In order to verify thermal comfort of a four-ducted air-conditioning system equipped on a highway sleeper bus, the test devices, such as anemoscope, K-type thermocouples and data acquisition instrument, were adopted to experimentally investigate the air supply parameters of the air-conditioning and temperature distribution of passenger compartment according to relative test standards. The results show that there exists the large difference of air supply velocity and temperature among the air supply outlets, and the air flow can not be organized efficiently. In the longitudinal direction of the passenger compartment, the relative high temperature exists in the front and rear part, while the relative low temperature exists in the middle part. The average temperature of left-bottom berths is higher than that of other berths. The temperature distribution of the passenger compartment is highly non-uniform and the average temperature is relatively low, which will not comply with the thermal comfort requirement of human body. 4 tabs, 10 figs, 12 refs.
