Chiller start and stop sequence

Chiller start and stop sequence to ensure that the air conditioning host to start after the normal operation, must ensure that:


① Condenser heat dissipation is good, otherwise it will be due to cold - coagulation temperature and the corresponding condensing pressure is too high, so that the cold water unit high voltage protection device action and stop, and even lead to failure.


② the cold water in the evaporator should be circulating, otherwise it will be due to cold water temperature is low, resulting in cold water temperature protection device action and stop, or because the evaporation temperature and the corresponding evaporation pressure is too low, is the chiller low voltage protection device action and stop Causing the cold water to freeze in the evaporator and damage the equipment.
