Abstract

The unitary-central air-conditioning system for the shop of production electronic equipment is considered as an example of energy-saving air conditioning system. The incoming outside air is prepared in the central, conditioner in compliance with sanitary standards on the quantity a moisture absorption. Tn the unitary fan air conditioners the air from the cent air conditioner is mixed with the cooled inside air and comes into the work zone with the temperature as selected according to conditions of comfort, j modes of operation of the unitary-central air-conditioning system in win and summer period are considered. The advantages of the described a conditioning system are presented in comparison to the central one.
