THE ANALYSIS OF FORCED-AIR AND EXHAUST INSTALLATIONS WITH HEAT RECUPERATING
The problem of energy saving concerns in particular agriculture where a high proportion of power resources are spent for a power feed, heating of heat-carriers for various technological needs, illumination of workshops, therefore use of the most effective энергосберегающих means and methods in the given area becomes an actual problem. One of forms энергосбережения and creations of optimum operating conditions of the attendants, as well as effective storage of technics at the enterprises of service is maintenance comfortable a temperature-moisture microclimate. For creation of these conditions forced-air and exhaust installations with a recuperator of heat can be used. Modern building materials allow reducing heat loss buildings and during too time does their tight, breaking air exchange. Forced-air and exhaust installations with a recuperator of heat restore air exchange without extra expenses for heating of fresh air; in turn recuperators allow reducing a high proportion of losses to heating of air. It is necessary to note, that compliance with sanitary norms on manufacture includes such important and problem item, as frequency rate of ventilation of facilities. The above impurity, the more intensively an exchange and is more frequency rate. Thus recommended excess of volume of acting air should make 10-15 %, creating superfluous pressure. Recuperator (from an armor. recuperator - regaining, returning) is the superficial type of heat exchanger, using heat of departing gases. In a recuperator heat exchange is carried out by continuous image through a wall dividing heat-carriers. Recuperators differ on relative direction movement of heat-carriers - counter flow, direct-flow; on constructional features - tubular, lamellar, ridge; to destination - heaters of air, gas, liquids, evaporators, condensers. In the given article the arrangement of industrial forced-air and exhaust installations with a recuperator of heat for heating of air in facilities of the enterprises of technical service is considered.
