Development of refrigeration equipment
Refrigeration equipment refers to the equipment mainly used for crew food refrigeration, all kinds of cargo refrigeration and cabin air conditioning in summer. It is mainly composed of compressor, expansion valve, evaporator, condenser, accessories and pipelines. According to the working principle, it can be divided into compression refrigeration equipment, absorption refrigeration equipment, steam jet refrigeration equipment, heat pump refrigeration equipment and electrothermal refrigeration equipment. Compression refrigeration equipment is the most widely used in ships. The heat of the object and its surroundings is removed through the working cycle of the equipment, causing and maintaining a certain low temperature state. The refrigerants used are mainly freon and ammonia, especially freon. However, due to the destruction of Freon on the atmospheric ozone layer, it has begun to be restricted by environmental regulations. Ammonia and other new refrigerants are being re used and trial produced.

Main Causes of Deterioration of Refrigerator Oil for Central Air Conditioner
1、 The main reasons for the deterioration of the refrigeration engine oil are as follows: 1. The water in the air is mixed into the refrigeration engine oil after it contacts with the refrigeration engine oil due to the infiltration of air in the refrigeration system; The main reason for deterioration of refrigeration oil of Wuhan Central Air Conditioner is that when there is more water in the refrigerant, the water will also be mixed with the refrigeration oil. When water is mixed in the refrigeration oil, the viscosity will decrease and the metal will be corroded. In the Freon refrigeration system, it will also cause "ice jam"; 2. During the use of oxidation refrigeration oil, when the exhaust temperature of the compressor is high, it may cause oxidation deterioration. Wuhan Central Air Conditioning, especially the refrigeration oil with poor chemical stability.
Working principle of water chiller
The chiller consists of four main components: compressor, evaporator, condenser and expansion valve, thus realizing the refrigeration and heating effect of the chiller.
Maintenance of water chiller
The startup and shutdown sequence of the water chiller shall ensure the normal operation of the air conditioning host after startup, and must ensure that:
