Abstract
The maximal effect of decrease (reduction) of the charge of energy in a complete set system of comfortable conditioned air refrigerating machinery is reached (achieved) at cumulative application of energetically rational structure of a complex and multiprocessor control system (MCS) by the equipment. MSC is carried out by controllers on the basis of the specialized digital processor DSP. The control system has low technological complexity, conformity to the standards on electrical parameters.
