Structure and Working Principle
1 Structure
The device consists of the refrigeration compressor main unit, heating device, electronic control box, cooling bath, cooling medium circulation system, and automatic alarm device. Structural diagram is shown separately.
2 Working Principle
After the refrigeration switch is turned on, the compressor starts operating, and the refrigeration system enters the formal working state. The refrigeration compressor works continuously. When the set temperature approaches, the heating device in the cooling bath proportionally supplies heat to balance the excess cooling capacity of the refrigeration system, thus achieving temperature stability. The stirring device continuously circulates the cooling medium inside the bath to ensure uniform temperature distribution.
