Abstract:
A comparative experimental study on the performance of dehumidifier equipped with thermosiphon heat exchanger and regular dehumidifier is conducted and a comparative analysis is carried out concerning the dehumidifying performance and energy saving property under the operating condition in which the ambient temperature equals to 27 ℃ and the air relative humidity is 60%. The experimental results indicate that under different Reynolds number conditions,the dehumidification amount of dehumidifier equipped with thermosiphon heat exchanger increases at least 24% and the specific power consumption decreases at least 20% compared with the regular dehumidifier. Besides,the moisture separation coefficient increases by more than 30% and the energy utilization is enhanced by at least 4.3 times. The result show that the dehumidifier equipped with thermosiphon heat exchanger has higher dehumidification performance and remarkable energy-saving effect. In addition,the relation among the dehumidification amount,Reynolds number and energy utilization is further analyzed and the correlation of the three factors is obtained.
