Dynamic Model Heat-Mass Exchange for the Water Cooler of the Industrial Air Conditioner

Mathematical modelling of processes heat-mass exchange for a water cooler, which is used in systems of an artificial microclimate for cooling and air unwatering, is observed. Based on the equations of material and thermal balance two equivalent models allowing to spend modelling of transients in a cooler on the basic channels of regulating and perturbation are gained. Sampling of dynamic model is defined by methods of a control system synthesis of the industrial air conditioner.

The study provides an insight into a calculation method of transient processes in the hybrid control system by a pulse characteristic of the plant.
