SEA LEVEL Diagramma psicrometrico dell’aria – Unità SI. If dbt and % Relative Humidity (RH) are known, then also it is possible to locate the point on the chart to read other properties of air.ASHRAE PSYCHROMETRIC CHART NO. In majority of situations, dbt and wbt of the air are measured to find the location of the point on the psychrometric chart. After locating the point of quality, many other properties can be easily obtained from the chart. It is necessary to know to parameters to locate the quality of air on psychrometric chart. The actual psychrometric chart is depicted in Fig. under different conditions using various psychrometric relations. The constructional procedure is of psychrometric chart is based on the calculations for relative humidity, enthalpy, specific humidity etc. ASHRAE has also developed psychrometric charts for other temperatures and barometric pressures. Psychrometric charts are readily available for standard barometric pressure of 101.325 kPa at sea level and for normal temperatures (0-50 oC). Fig.26.4 shows the schematic of a psychrometric chart. The left hand side of the psychrometric chart is bounded by the saturation line. Standard psychrometric charts are bounded by the dry-bulb temperature line (abscissa) and the vapour pressure or humidity ratio (ordinate).
It saves lot of time and labour required for calculation of different properties of air and such values can be directly read from the chart.
Using the chart, it is easy to obtained psychrometric properties of air and it helps to decide the various processes to be followed to achieve required quality of air. Psychrometric chart shows the inter-relation of all the important properties of air.
