The research purpose - the substantiation and system engineering of automatic control of exhaust ventilation in hen houses and pigstries which provides economical use of the electric power. Method of researches - the operational characteristics comparative analysis of automatic control system of exhaust ventilation with a voltage regulator and with the frequency current pulse width converter. Practical results - the new automatic control system of exhaust ventilation with frequency regulation which is mounted on the basis of control station of old system by replacement the voltage converter block to frequency converter block. The system allows to lower losses of energy in engines, to lower influence on a network feed and provides uniform ventilation of a premise. Branch of application - agriculture (exhaust ventilation systems of hen houses, pigsties and other agricultural premises). Product Description popup.authors popup.nrat_date 2020-04-02 Close
