Originální abstrakt
A set of measurements was performed in the experimental house in order to investigate the air velocities and the draft risk in the rooms during passive cooling. The hot-sphere anemometers with the air velocity range of 0.05 – 1 m/s were used for the measurements. The velocities in the air inlets were measured with the anemometer that had a range of 0.1 – 30 m/s. The indoor air velocities were measured at various locations at the height of 0.1 m, 1.1 m, and 1.6 m above the floor level. The 15 second averages of air velocities were recorded in the measurements. The air velocities above the beds were also investigated because passive cooling usually takes place at night. The measured indoor air velocities were relatively low, rarely exceeding 0.3 m/s. The highest velocities occurred at the floor level. Relatively high air velocities were observed in the vicinity of the inlets, but people are not very likely to stay close to the inlets (particularly at night). The air velocities exceeding 5 m/s were observed in the air inlets in some situations.
Český abstrakt
Článek se zabývá dopadem pasivního chlazení experimentálního domu intenzivním větráním na rychlost proudění vzduchu uvnitř experimentálního domu a s tím související tepelnou pohodu prostředí. Pro měření rychlosti proudění uvnitř domu byly použity žhavené anemometry s měřicím rozsahem 0.05 – 1 m/s. Pro měření rychlosti proudění vzduchu u vyústek pro přívod vzduchu byl použit žhavený anemometr s měřícím rozsahem 0.1 – 30 m/s. Naměřené rychlosti proudění vzduchu uvnitř domu jen velmi zřídka přesahovaly 0.3 m/s.
