MODEL-BASED COMMISSIONING METHOD FOR FIX-PLATE ENERGY RECOVERY UNIT IN BUILDING VENTILATION SYSTEMS

摘要

This paper describes a newly developed model-based commissioning method for the fixed-plate type energy recovery unit used in building ventilation systems to exchange heat between outside air and exhaust air. The model is developed through fitting manufacturers' specification data to simulate the performance of a fault-free fixed-plate type energy recovery unit. The model uses air volume flow rate as inputs to simulate the sensible heat efficiency and total heat efficiency of a fault-free energy recovery. Through comparing the simulated fault-free performance with the real performance of a fixed-plate type energy recovery unit, the automated commissioning for the energy recovery unit can be realized. The validity of the commissioning method is checked through commissioning a cross-flow fixed-plate type energy recovery unit really in use. The verification results show that this method can successfully realize the automated commissioning.
