Designing and manufacturing a refrigerator model that spans multiple evaporation modes and studying the influence of condensing temperature and evaporator temperature on the cabinet’s working efficiency

Abstract

Abstract: This paper presents the results of research, design and manufacture of a spreader refrigerator model for the training of thermal engineering students at Nha Trang University. The model is designed like a residential refrigerator, including the main equipment such as: Compressor, condenser, evaporator, filter and capillary and especially has 3 different evaporation modes to help the cabinet operate. generates a wide range of evaporator temperatures. In addition, the cabinet is equipped with additional measuring devices for operating parameters to facilitate the training and research process. In addition, research has shown the influence of evaporating temperature and condensing temperature on the performance of refrigerators...
