AIR CONDITIONING SYSTEM CONTROL DEVICE AND AIR CONDITIONING SYSTEM CONTROL METHOD

Title:

AIR CONDITIONING SYSTEM CONTROL DEVICE AND AIR CONDITIONING SYSTEM CONTROL METHOD

Document Type and Number:

WIPO Patent Application WO/2016/035121

Kind Code:

A1

Abstract:

An air conditioning system control device is provided with: a feedback control means (4) that generates a state quantity command from a control parameter and a difference between a target value of a room temperature and a measured room temperature, and that controls the room temperature to the target value on the basis of the state quantity command; a control object heat characteristic model calculation means (1) that, during normal operation, calculates a parameter of a model related to the heat characteristic of a control object (5) from at least a state quantity related to a quantity of heat supplied to the control object (5) or the state quantity command, and the measured room temperature; and a control parameter determination means (2) that determines the control parameter using a formula derived from the model related to the heat characteristic of the control object (5) and the parameter of the model. With the above configuration, since the parameter of the feedback control means is determined from data during normal operation, the need for a dedicated operation that may cause a deviation of the room temperature of the control object from the set target temperature can be eliminated, and the room temperature can be controlled to the target value continuously while the parameter is being determined, thereby providing the effect that comfort is not lost even while the parameter is being determined.
