marine air conditioning maintenance

Marine air conditioners are important equipment in marine electrical appliances. They can adjust the temperature and humidity inside the ship and improve comfort and health. In order to extend the service life of marine air conditioners, improve refrigeration effects, and ensure safety performance, we need to regularly clean, inspect, replace, and other maintenance work on marine air conditioners.

Clean the air conditioning system: The air conditioning system should be cleaned every month, including air filters, air ducts, air vents, evaporators, condensers and other components. When cleaning, cut off the power supply, use a soft cloth or brush to remove dust and dirt, and avoid using corrosive or flammable cleaning agents

Check the air conditioning system: The air conditioning system should be inspected every six months or every year, including components such as compressors, expansion valves, pressure switches, temperature sensors, solenoid valves, etc. During the inspection, you should pay attention to observe whether the working status and performance of each component are normal, whether there are any abnormal sounds or leaks, and whether there are damaged or loose components.

Replace the air conditioning system: Regularly replace consumables such as refrigerant, lubricating oil, and filter dryers in the air conditioning system based on usage conditions and manufacturer recommendations. Replacement should be carried out in accordance with the instructions or operating procedures to avoid refrigerant leakage or contamination, excessive or insufficient lubricating oil, and clogging or failure of the dry filter.

Using the air conditioning system: When using the air conditioning system, you should follow the instructions or operating procedures to switch, adjust, and control the air conditioning system correctly. Generally speaking, you should pay attention to the following points when using air conditioning systems:

Use the air conditioning system reasonably according to actual needs to avoid wasting energy or causing damage

Choose the appropriate cooling and heating mode and wind speed according to different climate conditions and seasonal changes.

Avoid frequently turning on or off the air conditioning system to keep temperature and humidity relatively stable

For air conditioning systems equipped with temperature and humidity alarm devices, the alarm value should be set within a reasonable range. If an alarm occurs, control measures should be taken immediately.
