Quality in ashrae psychrometric software#
Psychrometric Analysis, free psychrometric analysis software downloads. Ps圜hart - Psychrometric Analysis and Design Psychrometric Analysis. Note: Outer coefficient of heat transfer usually 3~10, >10 when winds.Įlite Software - 30 hvac software. Calculate duct flow resistance, environmental heat exchange, and adiabatic effect. Calculate air/liquid and round/rectangle cross section duct 2. Chart can be easily printed, copied to clipboard as bmp and wmf format, and exported as bmp, jpg, wmf or emf format. Chart plot/display setup and management support 12. Standards adoption Many states have adopted ANSI/ ASHRAE Standards 55-2004 on humidity and 62-2004 on IAQ into their building codes. Point state convert calculating, and give warning and error message, output point information if point state is OK 11. Now-days they use humidity meters that are accurate, more convenient, and usable in confined locations unsuitable for sling psychrometers. Convenient interface for process and mix point calculating 9. Many process point managements, include point pick up, data input grid, point definition select, point add, insert, reduce, delete, move up and down, open and save point list 8.
Quality has meaning only when the sub- cept of irreversibility provides. Chart grid snap, aided constant parameter lines across cursor point, middle button pan and mouse wheel zoom for convenient chart operating 7. Editor Related Commercial Resources CHAPTER 1 PSYCHROMETRICS Composition of Dry. Normal and eastern(China) style support 6. Mouse point catch, snap and calculation, output point information and many air properties 5.
Draw protractor for enthalpy-humidity and sensible-total heat ratio 4. Dry bulb temperature and humidity ratio axis range can be changed easily, the chart generation is automatic and fast 3. Use IAPWS-IF97 equation for water/vapor properties calculating, and treat moist air as real gas for high precision 2. Save and load data function for each data input grid, all input data can be saved for loading next time program started. Both Metric(SI) and English(IP) units support. This psychrometric chart use ASHRAE equations at normal temperature and pressure region and is perfectly consistent with all ASHRAE charts of No.1~7(SI Units) and No.1~5(IP Units). A convenient, precise and powerful tool for HVAC&R engineers.
