摘要
A spiral-coil heat exchanger consisting of a number of horizontal layers of spirally wound, finned tubes connected to vertical manifolds at the inner and outermost turns of each coil has been studied. A theoretical model predicting the thermal performance of the spiral-coil heat exchanger as a cooling and dehumidifying unit has been developed. Experiments on a laboratory model of the spiral-coil unit were conducted and the results obtained confirmed the theoretical predictions. Performance charts of enthalpy effectiveness and humidity ratio effectiveness vs Ntu suitable for air-handler unit design have also been presented. Copyright (C) 1996 Elsevier Science Ltd
