Summary

Central air-conditioning equipment, taking out heat gains merely by the air, are often designed with a partial circulation of reversing (recuperative) air. The conception that the reversal heat gain is achieved by such an action is disproved in the contribution and it is evidenced in the example that circulation is more demanding from the energy point of view than treatment of the ventilating air, only. It is stated therein that the volume of circulation during an extreme summer is decided by maximally allowable under-cooling of the distributed air limited with the dimensioning of the outlets. Efficiencies of methods using the reverse air as concerns rotational recovery heat exchangers installed in front of and behind the exchanger, are compared in the second part of the contribution.
