A psychrometric chart presents physical and thermal properties of moist air in a graphical form. Calculations of air properties otherwise are not very. This chapter will present a simple discussion of psychrometric charts and their uses with a minimum of theory.

SAM Chapter 630-16. Section 3A. THE PSYCHROMETRIC CHART AND ITS USE. Psychrometry is an impressive word which is defined as the measurement of the moisture content of air. In broader terms it is the science and practices associated with atmospheric air mixtures, their control, and the effect on materials and. Using the adiabatic mixing option of the ASHRAE Psychrometric program, the result for the mixed condition is 76.3 F db and 65.5 F wb with an enthalpy and humidity ratio of. 30.4 Btu/lbma and 0.0110 lbmv/lbma respectively. Using Chart 1 (IP) and locating the mixed state 3 three fourths of the distance from point. 2 to point 1. The psychrometric charts are diagrams giving the relationship between Tdb, Twb, Φ, ω and h (enthalpy) by assuming an ambient pressure. For example, ASHRAE psychrometric chart no. 5 is for 750 m. elevation (92.634 kPa barometric pressure) which may be used for. Ankara (see Fig. 7). Many psychrometric processes. Introduction. To establish proper comfort conditions within a building space, the designer must consider the air temperature and the amount of water vapor in the air. The latter is important because too high a level of water vapor can lead to uncomfortable feeling, sweat does not evaporate fast and people feel too wet and.
