An adjustably operable heat transfer system for cooling tower installations, the heat transfer units consisting of a section of only "wet" operating evaporative heat exchanger units and a section of dual-purpose heat exchanger units which are adapted for alternative or simultaneous wet evaporative heat transfer and "dry" convective heat transfer. All units are operated in the wet mode, when the air temperatures are highest, for maximum heat transfer output, but a mixed mode is used, when the air temperature is lowest, dry warm air obtained through convective heat transfer being admixed to the moist warm air obtained through evaporative heat transfer, in order to prevent cloud formation by the latter. |
