The article presents temperature variation and system efficiency: heat recovery-recirculation of exhaust air for two typical
air handling units (AHUs) configuration used nowadays in Poland. The selection of the proper AHU configuration is
critical from the perspective of energy consumption neccesary for fresh air treatment. In light of the ever-increasing
energy requirements for AHU’s, consideration of the configuration of the units is very important and should not be
shaped by equipment manufacturers, but by conscious designers of ventilation and air conditioning systems.
