Safety protection | With self-diagnosis function; Refrigerator overload protection; High pressure switch, overload relay, thermal protection |
| device, low liquid level protection, high temperature protection, sensor fault protection and other safety functions |
Closed circulation system | The whole system is a fully closed system, there will be no oil mist at high temperature, low temperature does not |
| absorb water in the air, the system in operation will not because of high temperature pressure rise, low temperature |
| automatically add heat conduction medium. |
