Marine air-conditioning is an air-conditioning system specially designed for ships, and its main function is to provide comfortable temperature and air quality inside ships. The working principle of marine air-conditioning is basically the same as that of ordinary air-conditioning, but due to the characteristics of the ship's environment, marine air-conditioning needs to have a higher degree of resistance and adaptability.

The main feature of marine air conditioners is that they are rust and corrosion resistant. As ships will be eroded by seawater when sailing at sea, marine air conditioners must have features to ensure their normal operation. At the same time, marine air conditioners also need to have anti-rust and anti-corrosion features to deal with salt and humidity in the sea water and other factors on the corrosion of equipment.

Another feature of marine air conditioning is good adaptability. Because the ship will be subject to different climatic and environmental influences during the voyage, marine air conditioning needs to have adaptive features to ensure that in different environments are able to operate normally. In addition, marine air conditioning also needs to have good seismic performance, in order to deal with the impact of the sea wind and waves and other factors on the equipment.

The working principle of marine air conditioning is basically the same as that of ordinary air conditioning, which mainly includes two processes: cooling and heating. In the refrigeration process, marine air conditioning through the compressor will be low-temperature refrigerant compressed into high-temperature and high-pressure gas, and then through the condenser will be cooled into liquid, and then through the expansion valve will be expanded into a low-temperature and low-pressure gas, so as to achieve the purpose of refrigeration. In the heating process, marine air conditioning through the reverse cycle of the way the outdoor low-temperature air into the room, and then through the heater will be heated, and then the hot air out of the outdoor, so as to achieve the purpose of heating.

The application range of marine air conditioning is very wide, mainly including passenger cabin, engine room, ship control room and so on. In the passenger cabin, marine air conditioning can provide passengers with comfortable temperature and air quality, thus improving passenger comfort and satisfaction. In the engine room, marine air conditioning can provide stable temperature and humidity environment for machines and equipment, so as to ensure the normal operation of machines and equipment. In the ship control room, marine air conditioning can provide a comfortable working environment for the crew, thus improving the crew's work efficiency.

In short, marine air conditioning is a kind of air conditioning system specially designed for ships, which has the characteristics of anti-rust, anti-corrosion, etc., and also has good adaptability and anti-seismic performance. Marine air conditioning has a very wide range of applications and can provide comfortable temperature and air quality inside the ship, thus improving the comfort and working efficiency of passengers and crew.
