FIELD: ventilation and air conditioning.
SUBSTANCE: device, method and complex of air heating are intended for recuperative air heating of rooms and their ventilation. Technical result is achieved by implementing the air heating method by the claimed air heating system, comprising a heat generating system, cooled connector, heat carrier transfer line, heated air transfer line and at least three heat exchanger units arranged in series, each of which contains at least one heat exchanger through which air is transferred. At the same time units of heat exchangers are located at points of intersection of heat carrier and heated air transfer lines, made heat-insulated, connector communicates the heat generating system with the heat exchanger unit closest to the heat carrier flow, and the air transfer line is under pressure. At that, the heat generating system is connected to the air preheating line supplied to the heat generating system inlet, note here that preheating line is connected with heated air transfer line.
EFFECT: higher efficiency and safety of air conditioning, including due to implementation of system with at least three units of heat exchangers, gradually changing temperature of media, and heat insulation of media transfer lines, which reduces heat losses that can damage surrounding lines of the structure.
