The price of cold-water maintenance, the maintenance of simulators, the maintenance of cooling equipment, cold-water maintenance plants, industrial chillers, coolers, freezers, cooling cabinets, cooling cabinets, etc., and the maintenance of cold-water units such as industrial refrigeration equipment maintenance companies: 1. The opening of cold-water units and the sequence of stoppages must ensure that air-conditioning hosts are functioning properly, and must be assured that the condensers are in good heat, or else they will stop because of the condening temperature and the corresponding condensation pressure, causing the cold-water-group high-pressure protection units to move or even malfunction. The cold water in the evaporation unit should circulate or otherwise be stopped because of the low temperature of the cold water, resulting in the movement of cold water temperature protection units, or because of the evaporation temperature and the corresponding low evaporation pressure, the movement of low pressure protection units in the chiller unit, or even the destruction of equipment caused by cold water freezing in the evaporation unit. Therefore, the order of opening of the chiller unit is: (must be strictly adhered to) the cooling tower wind engine, the cooling water pump, the cooling water pump, the cold water crew, the cooling machine, the cooling tower wind engine, the cooling pump, the cooling pump, the cooling pump, the cooling pump, and, when it is shut down, the cold water unit should be shut down half an hour before and the cold water pump, which will help save energy while avoiding failure and protecting the crew. 2 prior to the operation of the refrigeration cycle, it should be confirmed that all the heat-circle valves are closed. 2. Operation of the cold water unit1 preparatory work prior to start-up) confirms that the power supply of the crew and controller is in place. 2) confirm that cooling towers, cooling water pumps and cold water pumps have been activated. 3) confirms that the end-winding tubes have been powered. 2 normal operating 1) aircraft are fully operational, and the controller will monitor the oil voltage, electrical currents and other parameters of the system and, in the event of any problems, the control system will automatically take appropriate measures to protect the crew and display fault information on the crew screen. 2) within a 24-hour operating cycle, the crew shall be recorded at fixed intervals。
