This paper gives a detailed description of the instrument's development and realization. Through the improved digital PID algorithm the regulation of the dual output of heating and refrigerating has been realized; and problems such as the solenoid valve's poor reliability and vulnerability, which can cause the system to be out of control, have been solved successfully. Through the computer, this instrument can monitor, control and record the computer controlled process of cooling and benefit the research and development in low temperature biology and low temperature medicine.
