| 摘要： | Two layers of infrared-reflective (IRR) film were used in alternating combinations (no treatment, one layer, and two layers) over the driver-side window of a stationary car. In Phase 1 of the experiment, cabin air temperature was held constant at one of the two levels (75 degrees F and 90 degrees F (24 degrees C and 32 degrees C)) while subjects rated their thermal comfort. In Phase 2, air temperature was adjusted by fixed steps according to the subjects' responses (too hot or too cold). In phase 1, the IRR treatment significantly improved localized thermal comfort (on the left forearm, which was exposed to direct solar irradiance), but not whole body thermal comfort (although ratings for whole body comfort followed the expected trend). In Phase 2, IRR treatment resulted in subjects indicating that they were comfortable at an average air temperature of 2.5 degrees F (1.4 degrees C) higher than in the untreated condition. |
