通过对一定环境温度条件下的高温冷库中的氨蒸汽压缩系统进行分析,利用线性拟合的方法对氨的物性进行模拟,并对定冷凝温度和变冷凝温度时,制冷系统的各部件的损失和系统的炯用效率进行计算分析,得出在冷库氨蒸汽压缩系统中的蒸发器中的损失最大,压缩机和冷凝器次之的结果。提出要对冷库氨蒸汽压缩系统的性能进行改进,必须首先考虑提高其蒸发器、压缩机和冷凝器的效率着手;认为在一定环境温度条件下,降低冷凝温度是提高效率的较好的改进措施之一。
By analyzing the ammonia vapor compression system in a high temperature cold storage room under a certain ambient temperature, the physical property of the ammonia is simulated by a linear fitting method. When the condensing temperature and the condensing temperature are constant, the components of the refrigeration system The results show that the loss in the evaporator in the ammonia vapor compression system of the refrigerator is the largest and the compressor and the condenser are the second ones. In order to improve the performance of ammonia vapor compression system in cold storage, we must first consider improving the efficiency of its evaporator, compressor and condenser. It is considered that under certain ambient temperature conditions, it is better to reduce the condensation temperature and improve the efficiency One of the improvements.
