Summary

Gas-to-gas thermosiphon-based heat exchangers, working under various operating conditions covering the HVAC range of applications, were tested. The paper discusses the thermal performance of these units at very low air stream temperature differences (comfort-to-comfort applications). Effectiveness hysteresis has been observed and a novel heat pipe trigger designed such that when applied to the heat exchanger a wider operating range can be utilized. The paper presents a detailed description of effectiveness hysteresis phenomena, the effect of the implementation of the triggering system on the heat exchanger performance and prediction of the benefits of installation of such a trigger in a commercial application.
