DEVELOPMENT OF MULTIFUNCTIONAL ABSORBING SOLAR SYSTEMS ON THE BASIS OF FLUIDIZED BED HEAT-MASS-TRANSFER APPARATUS

The schematics of heat and mass transfer apparatus with the fluidized beds attachment "gas - liquid - solid body" for the evaporative cooling of environments (evaporative coolers of water (cooling towers CTW) and evaporative coolers of air (direct and indirect type coolers IECg and IECw) have been worked out. The multifunction solar refrigeration and air conditioning systems based on absorbing open-cycle with the indirect regeneration of absorbent were designed. In the drainage and cooling contours of solar systems heat and mass transfer apparatus with fluidized beds are utilized. Decisions for heat and mass transfer apparatus with the fluidized beds "gas - liquid - solid body" in a few basic variants, in particular, with possibility of placing of heat-exchanger directly in the volume of the fluidized beds have been elaborated, namely: evaporative coolers of air of indirect type (IECg) and evaporative coolers of liquid of indirect type (IECw) of cool contour of the solar systems; absorber-drier of the air flow and desorber-regenerator of absorbent of contour of drainage of outward air of the solar systems. The cycle of experimental researches of fluidizing bed "gas - liquid - solid body" features was executed both for a variant with the free fluidized bed of attachment and in a variant with placing of heat-exchanger directly in the volume of the fluidized bed of attachment. Influence of height of stationary layer of elements, geometrical parameters of distributive grate was studied, initial parameters of current of air, entering in the heat and mass transfer apparatus. On the basis of cycle of theoretical and experimental researches practical recommendations offer on determination of optimal geometrical parameters of basic elements and regime parameters of work of heat and mass transfer apparatus in autonomous behavior and in composition the multifunction solar absorbing systems.
