Mathematical Model of Heat Exchange for Non-stationary Mode of Water Heater

Abstract

The dynamical model of heat exchange for a water heater with lumped parameters, which can be used for synthesis of control systems by inflowing-exhaust ventilation installations, or industrial complexes of artificial microclimate, is considered. A mathematical description that represents the dynamical properties of a water heater concerning the main channels of regulation and perturbation is presented. Numerical simulation of transient processes for the VEZA VNV 243.1 heater according to the influence channels was carried out. The resulting dynamical model of a water heater can be the basis for the synthesis of automatic control systems and simulation of transients. A significant advantage of a mathematical model in the state space is the possibility of synthesis and analysis of a multidimensional control system.
