Marine air conditioning is an important living equipment on the ship, usually need to pay attention to the correct use and regular maintenance, to ensure the normal operation of the air conditioning and the comfortable life of the crew

Evaporator and filter: evaporator and filter are directly connected with the air in the air conditioning system, easy to accumulate dust, foreign matter and mold, affecting the cooling effect of air conditioning and air quality. Therefore, it is necessary to regularly clean the evaporator and filter with water or special detergent to keep it clean and dry

Check condensate discharge: Condensate is the water vapor generated in the air conditioning system. It is collected in the condensate pan and discharged through the drainage pipe. If the condensate tray or drainpipe is blocked or leaking, the condensate may overflow or backflow, affecting the air conditioner efficiency and safety. Therefore, it is necessary to regularly check whether the condensate pan and drainage pipe are unobstructed, and timely clean up foreign objects or repair leaks

Check refrigerants and lubricating oil: Refrigerants and lubricating oil are the working substances circulating in the air conditioning system, responsible for cooling and lubrication. If the refrigerant or oil is insufficient or of poor quality, the cooling effect of the air conditioner will be reduced or the compressor will be damaged. Therefore, it is necessary to regularly check the level, pressure, temperature and color of the refrigerant and lubricating oil, and timely supplement or replace the appropriate refrigerant and lubricating oil

Check compressors and fans: Compressors and fans are the power components in the air conditioning system, responsible for compressing and transporting refrigerant and air. If the compressor or fan is not working properly, the air conditioner will make more noise or stop working. Therefore, it is necessary to regularly check the current, voltage, vibration, noise and other indicators of the compressor and fan, and timely replace the damaged parts or repair the fault
