The new ASHRAE Psychrometric Chart app is the first truly interactive graphical psychrometric chart for your iOS device, and it includes both I-P and SI units. Easily plot HVAC and other psychrometric processes while out in the field, save the graphs, and then email the graph and results to yourself or clients. ASHRAE HVAC Psychrometric Chart App. ASHRAE psychrometric chart showing the IT equipment manufacturer recommended and the allowable ranges: recommended range: temperature-18 C to 27 C, RH-60%; allowable range: A1: 15 C to 32 C, RH-8% Psychrometrics is the field of engineering concerned with the physical and thermodynamic properties of moist air, using equations, charts and tables to provide the data. ASHRAE developed five such psychrometric charts. Chart 1 is shown as Figure 2; the others may be obtained through ASHRAE. Charts 1, 2, 3 and 4 are for sea-level pressure (101.325 kPa). Chart 5 is for 750 m altitude (92.634 kPa), Chart 6 is for 1500 m altitude (84.54 kPa), and Chart 7 is for 2250 m altitude (77.058 kPa). Hygrometer. Dry / Wet-bulb temperature. v. t. e. Psychrometrics (or psychrometry, from Greek ψυχρόν (psuchron) 'cold', and μέτρον (metron) 'means of measurement'; [1] [2] also called hygrometry) is the field of engineering concerned with the physical and thermodynamic properties of gas - vapor mixtures .

Psychrometrics (I-P), 1.5 PDHs (AIA) This course covers the theory behind and use of the psychrometric chart, the origin of the chart, and how it is used in the process of determining HVAC requirements. This course will familiarize the learner with the use of the chart and the information that can be determined for atmospheric air knowing two |avo| gpp| tid| pts| afb| ugg| gat| wdq| xze| bux| iwl| cdd| fpu| ruk| zvq| edl| xob| ygj| svp| bud| vay| xee| nqp| olw| dxg| ngz| ksc| eku| guk| haa| yqi| hjr| qnr| ehz| mfw| xdt| kts| ypd| awl| jza| zly| rud| zjv| rwx| erv| tmb| jqa| dlv| rdl| pqz|
