Abstract
Air conditioning systems for «clean rooms» are described. The operation of the central air conditioning system according to energy-saving technology is offered when only outside air is cooled and dehumidified in the central conditioner. Capital expenditures and energy consumption during operation are considerably reduced in this case.
