LABORATORY TESTING OF AN ENERGY EFFICIENT DEHUMIDIFIER FOR
WESTERN COOLING EFFICIENCY CENTER at
GREATER EFFICIENCY THAN HEAT PIPES
Plate heat exchangers have a two-step heat transfer process (air>fin>air) and experience no degradation of efficiency throughout a full range of temperature differences.
Heat pipes, on the other hand have a six-step heat transfer process (air>fin>tube>fluid>tube>fin>air) severely inhibiting overall heat transfer. Additionally, lower temperature differences greatly affect the rate of fluid movement, further reducing heat pipe efficiency at lower temperature differences.
