Abstract

Results of experimental study of reversible heat exchange with water–ice phase transition in filtering the airflow through a tube heat exchanger are presented. The heat exchanger is made of thin-walled plastic tubes (3 and 5 mm in diameter) filled with water and sealed at both ends. The heat exchanger was tested in a laboratory setup with a Ranque tube applied to create a flow of cold air. The heat exchanger operation was investigated in steady-state and various reversible modes. Themeasurements showed the possibility of substantially increasing the time between switching the direction of airflow with maintaining a high coefficient of heat regeneration. The results can be used in the development of regenerative heat and mass transfer devices, including VENTIREG systems of ventilation emission heat regeneration.
