Type of article: Article

Summary

Measurements made correspond to the operating conditions of a heat pump in the heating mode. The range of test parameters in the study includes the evaporating temperature from -15 to 5 °C, the refrigerant mass flux from 70 to 211 kg/m2 and the heat flux from 5 to 15 kW/m2. The objective is to evaluate the effectiveness of the micro-fin tube over the smooth tube as a function of the evaporating temperature and tube diameter.
