摘要
Abstract
A new type of capillary tube combination unit was studied,which enabled more flexible refrigerant flowing than traditional capillary tubes. With a homogeneous-phase model,the refrigerant flowing rate of the capillary tube combination unit and that of the traditional capillary tube were calculated and compared at different parameters and working modes. The results indicated that the capillary tube combination unit met the refrigerant flowing needs much better in refrigerators&heat pumps. An experimental R22 refrigerator&heat pump was built with a capillary tube combination unit,and its performance was experimentally studied. The study showed that the capillary tube combination unit could match the cooling or heating load under typical toorking conditions,and it could provide different refrigerant flowing rates for cooling and heating modes at given inlet and outlet parameters.关键词
