Windage or Drift Loss Calculation: Drift loss of the cooling tower is normally provided by the cooling tower manufacturer based on the Process design. The main objective of the HVAC design calculations project is to provide correctly sized heating, ventilation and air conditioning systems for the building. �C*�����P�י�N���g@��8r���9�K� V�D(9�@�Q��R> VJ*ن������xH\�#�B S�>Kq��;D�K� V�T�0T �nK� X)�옭���o�/�`�F��t�%��� h�b```b``�``a``)`b@ !V6�8�TFAAaA� k}_(�000r8�L��|�|�����u,-,��e1olaa:ǰ#�b�� �)+�)����J�s���l����Ej�Bg�{f| �e��K��E��I���e�'j�.ީ��-}�ۖ��e�M�~v���>�Ld�]�!k��,p�l��H�s�m�f|�4��T��sK#M'Yn��y16̻uۄ�gB�������&�L�]�?/銛Ed��j�N>��;�E Oversize the chiller by 20% Ideal Size in Tons = Tons x 1.2.
