Generally, after companies have used air-cooled chillers for a long time, they are prone to various failures due to the lack of necessary maintenance and maintenance. Faced with the occurrence of failures, companies need to conduct detailed inspections of the operating conditions of the various components of the equipment in time. For refrigeration systems, electrical systems, wind systems, and water systems, they need to conduct key inspections to determine whether their operations are normal. Next, I will show you how to deal with common system problems.
1. Refrigeration system: Check whether there are cracks, damage, frosting and condensation in each pipeline in the refrigeration system of the air-cooled chiller; No friction and friction, especially in the welding place of the refrigerant pipeline, whether there is leakage in the joint of the air-cooled chiller, if there will be oil in the leakage place, you can also use a clean soft cloth or soft paper to scrub the pipeline weld and joint At the connection point, investigate whether there is oil pollution to determine whether there is leakage.
2. Electrical system: Check whether the fuse of the electrical system of the air-cooled chiller is blown, whether the insulation of the electrical wire is intact, whether the circuit board is cracked, whether the connection is loose, etc. Especially if the electrical connection is excellent in touch, the wiring screws and connectors are easy to loose and cause poor touch.
3. Ventilation system: check whether the air filter, heat exchanger coil and fins of the air-cooled chiller are too dusty; whether the air inlet and outlet are dredged; whether the fan and fan blades work normally; Is the size normal, is the water system normal, etc.?
4. Water system: Check whether the water system of the air-cooled chiller is leaking; whether the water inlet and outlet are dredged; whether the water pump works normally. Listen to the power on and listen to the compressor working sound of the air-cooled chiller to see if it is normal, if there is any abnormal noise, if there is any noise in the operation of the electric fan, water pump, and if the noise is too loud, etc. When the air-cooled chiller is working, the vibration is slight and the noise is small under normal conditions.
