• System Builder - Ductwork - Outlets - Re-calculate Airflow: Recalculate airflow for multiple rooms at one time.

    Hi I am currently sizing ductwork in System builder and I noticed the airflows didn't match my heat load calc. I went through and found that although I had done multiple revisions of adjusting the heat load the air flow in the room for ductwork design…
  • Room Pressure Calculation/Analysis

    I'm working on a project that involves analyzing room pressures to maintain pressurization and I'm wondering whether it is possible to use HEVACOMP to calculate and analyse room pressures. I've tried to use HEVACOMP simulator with no joy. Any suggestion…
  • RE: Louver for heat gain/loss calculation as well as air flow simulation?

    You should use the flowpath data options for setting up general airflows. Use opening window definitions purely for opening windows. The transfer grille option should suffice for setting up a louvre. Please note that airflow paths and opening windows…
