The marine condensing unit is widely used in all kinds of passenger ships, cargo ships, and oil platforms because of its novel design, convenient operation, stable work, safety, and convenient maintenance. And how does it work?
The refrigeration principle of a general refrigerator is that the compressor compresses the working medium from low-temperature and low-pressure gas into high-temperature and high-pressure gas, and then condenses it into a medium-temperature and high-pressure liquid through a condenser. After throttling by a throttle valve, is a liquid of low temperature and low pressure.
Low-temperature and low-pressure liquid working fluid into the evaporator, evaporating in the evaporator to become low-temperature and low-pressure steam, again into the compressor to complete the refrigeration cycle.
The marine condensing unit mainly consists of the compressor, condenser, control box, etc. . The structure of the condenser is from the tube-type to tube-type development, and mainly to parallel flow development. In order to improve the heat transfer efficiency and reduce the weight, the internal structure of cascaded and parallel flow condenser has been developed from a unit parallel flow to a multi-element parallel flow condenser. By reducing the thickness of the fin, increasing the inner fin of the tube, and changing the fin shape and the opening angle, the heat dissipation area of the fin is increased, and the heat exchange efficiency of the gas side and the liquid side is enhanced.
The condenser in the marine condensing unit is a heat-emitting device that transfers the heat absorbed in the evaporator to the cooling medium along with the heat transferred by the compressor. The throttle valve controls and adjusts the amount of refrigerant liquid flowing into the evaporator, and divides the system into two parts: the high-pressure side and the low-pressure side.
The above is the principle of the marine condensing unit, I hope to help you, and if you have any other questions, you can contact us at any time.
