Simulation of HVAC Equipment in the DOE-2 Program

摘要

General considerations and models used by the DOE-2 program for the simulation of residential and commercial HVAC equipment are discussed. The use of transfer functions and linear controller models allows strong coupling between the envelope and the equipment models while the simulation of envelope and equipment configurations is performed sequentially, resulting in significantly reduced computation time. Empirical formulations of equipment models allow fast calculations without sacrificing sensitivity to primary physical parameters. A semi-iterative (up to three iterations) approach can produce accurate simulations of interacting control systems without a significant increase in computation time. (ERA citation 08:033893)
