Research on Key Parameters of Building Load Model for Dynamic Performance Measurement of Air Conditioner
Published 2025-01-01“…Given that the steady-state condition measurement in the laboratory cannot fully reflect the actual performance issues of air conditioners, the dynamic performance measurement of room air conditioners based on virtual buildings has become a current research hotspot. This paper determines the key parameters for the dynamic performance measurement of room air conditioners through simulation and model analysis methods: the load point of the building, the zero-load point, the heat and cold ratio, the sensible heat ratio, the selection coefficient, and the effective heat capacity and moisture capacity of the room. …”
