When organising the air humidification process in entomological production premises, it is necessary to ensure a high level of the equipment efficiency with the minimisation of the non-productive water consumption and the reduction of the energy consumed during the process. There is proposed a variant of an improved compact heat and mass exchange equipment for a microclimate creation system in the entomological industrial premises, in which the humidification process of the air flow takes place by direct contact with water inside of regular packages with a developed system of channels. The most modern package elements are made on the basis of corrugated sheets. The purpose of the work is to determine the optimal dimensions of the humidification packages in the aspect of aerodynamics and the air humidification efficiency for the development of efficient humidification devices, applied in microclimate creation systems for the entomological production premises. New types of regular packages are used, formed from sheets that are characterised by a high degree of wettability due to the structure of materials or a special surface geometry. Optimal geometrical dimensions of the package in the humidification device are determined taking into account aerodynamics and the efficiency of air humidification, and ensuring minimisation of the water costs as well. Experimental tests were carried out on the effect of the layout dimensions of regular packages for the humidification devices used in the air conditioning systems. A comparative assessment of the ratio of the layout dimensions of the regular structured packages is given. The depth of the humidification package should not exceed 0.5 m. Packages, made from corrugated RN plates or GLASdek polymer sheets, are more preferable than PET packages.
