Chvac is a program that quickly and accurately calculates the maximum heating and cooling loads for commercial buildings. The program allows an unlimited number of rooms which can be grouped into as many as 100 air handling systems. Chvac automatically looks up all cooling load and correction factors necessary for computing loads.
v8.1 [Mar 12, 2012]
Fixed a bug on the Typical Equipment Cooling Loads window when selecting gas or electric hooded cooking appliances, where the radiation factor shown was being used instead of being ignored and instead using 100%. Since hooded appliances have only radiant sensible gains and no convective, then the practical value to copy back to the Equipment Cooling Loads window's Percent Radiant column is 100%. Also fixed a bug on the Typical Equipment Cooling Loads window for the same gas or electric hooded cooking appliances, where the Sensible Nominal column was not being converted to watts if you selected "watts" in the Quantity Type - Sensible input at the top of the window.
Fixed a bug that could occur with some regional and language option settings, where some of the numbers on some of the reports could not show up at all sometimes.
Adjusted the formatting on part of the Psychrometric Report to prevent a rare problem where some numbers were not showing up on some computers.
