Marine Refrigeration System Working Principle

At 5 000 feet water boils at 202 f.

Marine refrigeration system working principle.

This principle is applied in the refrigeration system. Basic refrigeration system fundamentals the compression cycle. It causes refrigerant to flow and is where energy is applied to perform the work of removing heat in the evaporator. This guide describes the principle and working of marine refrigeration system along with the important components and refrigerants used.

The refrigeration system comprises of various components like freon gas compressor condenser evaporator thermostat etc which are all enclosed in a casing. Understanding the basics is the key to properly plan the maintenance and troubleshoot the marine refrigeration system. The working principle of a refrigerator and refrigeration in general is very simple. The compressor is the mechanical heart of a refrigeration system.

The most commonly used refrigeration machines are the household refrigerator and deep freezer though these machines are available in many other forms. The basic components of any refrigeration system working on the vapour compression cycle are the compressor condenser expansion valve evaporator and the refrigerant fluid which is alternatively vapourized and liquefied during the refrigeration cycle. The pressure temperature relationship is an important principle for refrigeration. The compressor serves two functions.

For example at sea level water boils at 212 f. Sockets provided on deck. Refrigeration basic principle applies on all system whether it s the smallest water cooler to largest walk in freezer that ever built. It involves the removal of heat from one region and its deposition to another.

Freon gas or the refrigerant absorbs heat inside the area to be cooled in the evaporator unit and transfers that heat to the refrigerator s condenser at exterior. In reefer ships the temperature of the perishable or temperature sensitive cargo such as food chemical or liquefied gas is controlled by the refrigeration plant of the ship. When you pass a low temperature liquid close to objects that you want to cool heat from those objects is transferred to the liquid which evaporates and takes away the heat in. Individual containers with their own refrigeration plant are connected to the 440 or 220 a c.
