POWER SAVING AT OPERATION OF THE SUPPLY VENTILATION SYSTEMS AND AIR CONDITIONING

The paper considers the method for calculating the branched air-supply systems, ventilation and air-conditioning. This paper presents a small segment of power saving tasks in the ventilation and a microscopic segment of the huge complex problems rational use of energy with the necessary reduction of harmful impact on the ecology of the system environment. The method of calculating the air supply ICU-ventilation and air conditioning is considered. The aero-dynamic calculation of fresh air system with fan was carried out according to this methodology and the "working" point was found. In a specific example, the technique evaluation of technical solutions made at the design stage in order to reduce the total cost of establishing and operating air supply system that supplies air to several pro-industrial premises and technological units. Quantitative techno-economic analysis of 3 variants of the air-supply system is given (with calculations of the payback period) for applying of a predetermined amount of air with over-pressure data in three rooms. Special recommendations on power saving during exploitation of ventilation and air conditioning systems are also given.
