摘要：研制了一种适于高精度低温实验的新型低温恒温槽,以复叠式压缩制冷为冷源,利用R13压缩自身产生的热能,通过电磁阀辅热温度控制方法调节控制浴槽温度,控制温度范围-6^-78℃,控制温度精度0.1~0.3℃。
A new precise low temperature thermostat bath was developed,in which a cascade compression refrigeration cycle is utilized,the heat energy is produced by the low temperature refrigeration system,and the refrigerating capacity is counteracted by heating of the solenoid valve.The temperature fluctuation is from 0.1 to 0.3 ℃ within the range from-6 to-78 ℃.The bath is better than other domestic congener products.
