modelControlerHeatRecovery
controler for heat recovery system with fixed efficiency
Information
This model implements a control strategy for the heat recovery system. It switches between heating and cooling mode depending on the outdoor air temperature and exhaust air temperature. The output is the bypass opening value between zero (closed) and and one (fully opened).
