AI Technical Summary
Existing dual-refrigeration loop systems have complex piping structures and are difficult to control. Furthermore, the heat exchange area of the other system cannot be utilized when one system is operating. There is an urgent need to simplify the system structure and reduce the difficulty of control.
Multiple expansion valves, evaporators, and compressors are integrated into a single refrigeration system using a parallel configuration. The piping connections are controlled by electric valves, simplifying the piping structure and maintaining system stability and redundancy in the event of compressor failure.
The system's piping structure has been simplified, control difficulty has been reduced, the control flexibility and stability of the refrigeration system have been improved, redundancy has been enhanced, and heat exchange efficiency and energy efficiency have been increased.
