国外对吸收式制冷机的工质研究已从二工质对转向三工质系.日本在H_2O-LiBr、C_4H_6O_2(水-溴化锂-丁内酯)三工质系的吸收式制冷机方面进行了研究.在该工质系中,H_2O和C_4H_6O_2之比为20∶1摩尔.现已有该工质系的热力性质图表。本文研究了用于该工质系的缓蚀剂.研究过程巾进行了连续和间断沸腾试验和电腐蚀试验,添加了有机和无机缓蚀剂.结论如下:与其它的工质系相比较, Abroad, the study on the working medium of absorption chiller has been changed from two working pair to three working one.Japan was carried out on the absorption chiller of H_2O-LiBr, C_4H_6O_2 (water-lithium bromide-butyrolactone) In this working system, the ratio of H 2 O to C 4 H 6 O 2 is 20: 1, and the thermodynamic properties of this system are now available. In this paper, we studied the corrosion inhibitor used in this working fluid system.We conducted continuous and intermittent boiling test and electro-corrosion test of the process towel with addition of organic and inorganic corrosion inhibitors.The conclusions are as follows: Compared with other working fluid systems,
