中央空调制冷设备的保养,以水冷螺杆式冷水机组为例,保养内容及顺序:每天每次检查压缩机的油压及油量;探测系统是否有制冷剂泄漏;运转冷水机组,检查操作状况;检查异常的声响、震动及高温状况;检查冷媒运行中冷凝器及冷却器的温度、压力;检查运转部分润滑情况及添加适当润滑油;检查冷水机出入水温度及压力;检查各阀门。最后书写检查报告。每年都应检查项目:检查或更换冷媒、干燥过滤器、压缩机润滑油;检查压缩机电动机绝缘情况,应大于10MΩ;检查
Central air conditioning and refrigeration equipment maintenance, water-cooled screw chillers, for example, maintenance content and order: every day to check the compressor hydraulic and fuel; detection system for refrigerant leaks; run chillers, check the operating conditions; Check the abnormal sound, vibration and high temperature conditions; Check the refrigerant in the operation of the condenser and cooler temperature and pressure; Check the operation part of the lubrication and add the appropriate lubricant; Check the chiller access to the water temperature and pressure; Check the valves. Final writing inspection report. Check the project every year: Check or replace the refrigerant, drying filters, compressor oil; Check the compressor motor insulation, it should be greater than 10MΩ; Check
