摘要
Abstract
Experiments on the refrigerant charge amount were conducted for a three-pass condenser with inlet and outlet headers arranged on opposite sides and a two-pass condenser with a subcooling zone placed above,and comparisons were made with a conventional two-pass condenser.The results showed that:for the conventional condenser,a distinct subcooling platform was observed,and the charge amount was about 155 g.For the three-pass condenser,due to heat transfer from the high-temperature inlet through the connecting pipe,a short subcooling platform(about 61 g)was caused;after the position of the connecting pipe was optimized,it was increased to 159 g.For the condenser with the subcooling zone placed above,no subcooling platform was present due to back-suction of gaseous refrigerant;after the relative position of the conduit and the connecting pipe was optimized,the platform appeared normally(about 280 g).Simply increasing the internal volume of the receiver was found to be ineffective.The subcooling platform could be improved by optimizing the structure,and the charge amount was made to approach the theoretical value.关键词
