SIMULATION OF HEAT AND MASS EXCHANGE PROCESS HEAT EXCHANGER OF SIDE-EVAPORATIVE TYPE

It is known that the share of influence microclimate on productivity animals about 20-25%. In process life, emit a large amount heat, moisture, harmful gases, including carbon dioxide, ammonia and hydrogen sulfide. If ventilation system does not work satisfactorily, concentration water vapor gases may exceed standards, as result which drastically reduce die. Currently, when creating livestock enterprises, it necessary to resolve issues related reduction investments, 40% equipment. More than 20% cost equipment falls heating system; they most often try save money. Disagreements arise between specialists deviation parameters from optimal values for productive qualities farm animals. The article presents physical mathematical apparatus methods simulating heat mass transfer in an indirect-evaporative type exchanger buildings. description indirect evaporative Maisotsenko cycle complex requires solution many important problems (for example, algorithmic combined surface with existing walls). Of particular importance development efficient algorithm allows one calculate differential equations partial derivatives. Therefore, aim research describe simulation technique (numerical simulation) exchanger. As analytical studies, physico-mathematical was compiled, energy balance equation, taking into account sensitive latent wall wet dry channels. initial limiting conditions model working part cooler under study are determined, form basis numerical Star CCM+ software package. A modeling) has been developed preliminary studies Maysocenka have carried out. simulation, distributions temperature field, vector field velocities absolute humidity air flow were obtained.
