Agent Utility Suite
HVAC coil load calculator: from airflow and entering/leaving air (any two properties each), the sensible, latent and total load, tons, SHR and condensate; or one state plus loads to solve the other. Outdoor/return air mixing and outdoor air % back-calculation. ASHRAE psychrometrics, elevation, IP or SI. Shows every step with the numbers. $0.002 USDC per call.
