Thermal comfort and skin temperature responses to the supplied air from personal air nozzles in aircraft cabins
For investigating the thermal comfort impact of supply air from personal nozzles on body positions of human bodies in aircraft cabins, a mock aircraft cabin with three rows of seats was built to investigate the effect of personal nozzle on thermal comfort of three main body parts, including head, upper body and lower body. In total, 12 tests were performed on 16 volunteers. Every test lasted 3 h and 40 minutes. Simultaneously, volunteers’ responses for both local and overall thermal responses were recorded. Skin temperatures were monitored. The results showed that when cooling the upper body, variation in local thermal sensation, overall thermal sensation and average skin temperature were the most significant responses produced by 16 young healthy human volunteers taking part in the experiment. However, for the airflow sensation, the strongest impact was at the head (including forehead and face), followed by the upper body part (breast, back, shoulder, abdomen) and then the lower body part (buttock, sex organ, thighs, legs and feet). In order to minimize draft discomfort, the air supply from nozzles should be delivered directly to the upper body, which would make the passengers more comfortable and benefit the optimization of the design of the nozzle.
