I found this, but I'm not quite sure how to gather what it says correctly.

Performance of a thermosiphon loop indicates an effectiveness of between 40% and 60% when the overall temperature difference is over 40°F and with face velocities of 250 to 600 feet per minute. For example, if entering air at 80°F is cooled by the thermosiphon evaporator to 70°F and the air off the cooling coil is reheated from 55°F to 65°F by the condenser section, the effectiveness is 40 % [=(65-55)/(80-55) = 40%].
