The proposed comfort zones show that subjects are comfortable up to 32 ☌ at still air condition (0 m/s–0.2 m/s) and up to 35 ☌ at higher speed (up to 1.5 m/s) in naturally ventilated buildings in the composite climate of India.Ashrae Psychrometric Chart Si Units Pdf Downloadĥ4 Ashrae psychrometric chart Nº 01.pdf - Free download as PDF File (.pdf), Text File (.txt) or view presentation slides online. This Psychrometric Calculator allows you to compute moist air properties given only altitude, dry-bulb temperature and either wet-bulb, dew point or relative humidity. New extended boundaries of comfort zones are proposed considering various adaptations specific to this region, including the role of air speed to offset the temperature. 5 normal temperature, elevation 750 meters (Reprinted with permission of the American Society of Heating. Results from this study indicate that subjects in naturally ventilated buildings of this region are comfortable at temperatures different from those suggested by ASHRAE 55 and ISO-7730 standards. Figure 1212 ASHRAE psychrometric chart No. Comfort boundaries are defined based on climate specific adaptations, the role of air speed and thermal preferences. The method of calculation suggested by the ASHRAE 55-2013 and ISO-7730 were followed to determine extended acceptable temperature ranges for comfort at elevated air speed. In the present study, ASHRAE comfort boundaries at three different air speeds - still air (up to 0.2 m/s), natural air flow (0.2 m/s–0.5 m/s) and forced air flow with ceiling fan assist (0.5 m/s–1.5 m/s) are investigated.
A thermal comfort field study was conducted in 32 naturally ventilated buildings, collecting a total of 2610 samples spread over a total period of four years, covering all seasons, wide age groups, clothing types, and building types. The current comfort standards do not reflect the cultural and climatic diversity of India.
Thermal comfort standards such as ASHRAE 55-2013 defines comfort boundaries which are based on the experimental results conducted in climatic chambers and field studies.
