MODELING METHOD/DEVICE FOR AIR CONDITIONING SYSTEM

摘要

PURPOSE: To attain the modeling of an air conditioning system by applying the inputs of a kinds to measure the outputs of β kinds and producing a model to describe its characteristic based on the input/output data. CONSTITUTION: Two output data are outputted from a data processor and applied to a cold water valve and a steam valve as the control signals (step 101). The temperature of air supplied into a room is measured by a sensor and the temperature data are outputted to the data processor. The data processor produces an AR model of an air conditioning system based on the temperature data (step 104). Then, a cooling and heating system models related to the input data used for both cold water and steam valves are produced based on the AR model (step 106). And, the data processor decides the PID parameters of both cooling and heating systems based on the cooling and heating models respectively (step 107).
