  • Modelling and experimental evaluation of a condenser for a heat-pump tumble dryer [Elektronski vir]
    Petelin, Nada, 1992- ...
    This article reports on the development of a mathematical model for a finned tube condenser, which is a part of the heat exchanger in a heat-pump tumble dryer. The purpose of this model was to ... determine the number of tube rows with respect to the minimal mass and volume of the condenser, while maintaining the energy efficiency. The analysis was based on the [epsilon]-NTU method, which was further evaluated by the experimental data obtained from measurements performed on a commercial heat-pump tumble dryer. The model can be broadly used for different geometries, refrigerants and air velocities to evaluate the condenserʼs performance. The numerical results show good agreement with the experimental data; the difference between the predicted and measured outlet air temperatures being less than 4.5%. According to the numerical results, a new condenser, with a 28.5% reduction in the initial size, was designed and tested.
