Maintenance of water chiller
Author:
The startup and shutdown sequence of the water chiller shall ensure the normal operation of the air conditioning host after startup, and must ensure that:
① The heat dissipation of the condenser is good, otherwise, the high cooling condensing temperature and the corresponding condensing pressure will cause the high-pressure protective device of the chiller to act and stop, or even cause a failure.
② The cold water in the evaporator shall circulate circularly, otherwise, the cold water temperature protection device will act and stop due to the low temperature of the cold water, or the low evaporation temperature and corresponding evaporation pressure will cause the shutdown due to the action of the low pressure protection device of the chiller, or even cause the cold water in the evaporator to freeze and damage the equipment. Therefore, the starting sequence of the chiller is: (must be strictly observed) The cooling tower fan is on -->The cooling water pump is on -->The cooling water pump is on -->The starting sequence of the chiller is: (must be strictly observed) The chiller is off -->The cooling tower fan is off -->The cooling water pump is off -->The cooling water pump is off
