Abstract
Introduction. The article deals with the issues related to provision of air humidity parameters required for non-hazardous operation of various technical facilities. 
 Problem Statement. The paper considers analytical methods for energy efficiency assessment of adsorption and condensation methods of air dehumidification, which provide safe microclimatic working conditions, and the influence of the operating modes of dehumidifying plants on the parameters of the microclimate. 
 Theoretical Part. As indicators of the energy efficiency of each of the methods, it is proposed to use the energy costs that are minimally necessary for the implementation of ideal physical dehumidification processes and per unit mass of water units emitted from air. This ensures safe and comfortable microclimatic working conditions with minimal energy costs. The ratio of the specific energy costs of the condensation and adsorption methods shows their comparative efficiency. An electronic Id-diagram was used to determine the air parameters in the implemented dehumidification processes (cooling, condensation and adsorption of water vapor).
 Conclusion. Analytical dependences are obtained for the analyzed energy efficiency indicators that provide safe and comfortable microclimatic working conditions with minimal energy costs. Numerical estimates were carried out according to the most probable modes of dehumidification processes and air parameters. The parametric restrictions on the implementation of the adsorption dehumidification method are justified, in which it becomes energetically more profitable. The conditions under which it is possible to implement a combined dehumidification method to ensure safe microclimatic working conditions are determined.

Количество теплоты Qх, кДж, отводимой холодильной установкой от воздуха, для реализации процессов охлаждения и конденсации водяных паров с их последующей кристаллизацией на охлаждающей поверхности, определяется по формуле
При необходимости получения не только сухого, но и охлажденного до низких температур воздуха, который предотвращают появление опасных производственных факторов, связанных с недопустимым повышение температуры (например, в холодильных установках морозильных камер, авторефрижераторов, системах холодоснабжения специальных сооружений и др.), конденсационный способ энергетически является самым выгодным
Summary
The article deals with the issues related to provision of air humidity parameters required for nonhazardous operation of various technical facilities. Что существенное влияние на эффективность процесса уменьшения влажности в помещении для обеспечения безопасных микроклиматических условий труда оказывает не температура подаваемого внутрь воздуха, а его влагосодержание, т.е. Затраты энергии на реализацию процесса охлаждения воздуха являются основными при конденсационном способе осушения, но не единственными.
