Résumé

In the present study, condensation and evaporation local heat transfer coefficients of the R1234ze(E) inside a brazed plate heat exchanger were investigated by using a test section which is combined with two grooved stainless steel plates. In the test section, wall temperature distribution was measured. The test section consists of eight plates; two of them were processed herringbone for refrigerant flow channel other two flat plates are set for cooling plate for refrigerant, and another consist on cooling water flow channel. In order to measure local heat transfer and temperature distribution, five thermocouples were set at not only flow direction but also in the right and left sides of plates. Local heat transfer coefficient and temperature distribution were calculated from wall temperature and local heat flux with downward and upward flow condition.
