Abstract
New standards with regards to systems of heating, ventilation, air conditioning and building climatology introduce considerable changes when choosing the regimes of preparation ofthe conditioned air. A higher humidity of the outside air design parameters has required obligatory use of the regimes of refrigeration and drying of the inlet outside air. Based on the use of York equipment, energy efficient air conditioning systems are being developed.
