Annotation Purpose. Investigate the possibility of ensuring a high level of efficiency of humidifiers in entomological production facilities that use out-of-circulation water cycle, while minimizing (or no) non-production water consumption and reducing energy consumption for the process, given the high dust content in indoor air. Methods. Using the requirements for materials for the manufacture of regular nozzles of film humidifiers in entomological production, ways to increase their efficiency are substantiated. The aerodynamic and kinetic characteristics of nozzles made of various materials PET (Ukraine), GLASdek3 (Sweden), PVC (Netherlands) were experimentally determined. Results. New types of regular nozzles RN are proposed, formed by sheets that have a high degree of wettability due to the applied materials or special surface geometry, and provide high efficiency of the wetting process. Conclusions 1. The study of the aerodynamic characteristics of nozzles made of various materials showed that The study of the aerodynamic characteristics of nozzles made of various materials showed that GLASdek3 and PET nozzles have advantages in terms of air resistance, for which aerodynamic drag in the operating range of airflow rates of 1.5...4 m/s is 75...450 Pa, which is 2–4 times less than for PVC nozzles. 2. At the same values of the degree of efficiency for the GLASdek3 and PET nozzles are characterized by lower values of specific energy consumption. The energy efficiency of these nozzles is approximately 1.5 times higher than that of PVC nozzles. 3. Economic analysis proved the feasibility of using nozzles made of PET sheets of domestic manufacturers, which are characterized by lower cost than modules of GLASdek3 nozzles with similar characteristics. 4. It has been established that miplast acts as a material for film humidifiers in terms of efficiency on a par with GLASdek3 and PET, however, it is not recommended to use it to create thermal humidity parameters in entomological production due to the porosity of the structure and the inability to clean it from dust.
