Marine Refrigeration System Working Principle

Individual containers with their own refrigeration plant are connected to the 440 or 220 a c.

Marine refrigeration system working principle.

Basic refrigeration system fundamentals the compression cycle. This principle is applied in the refrigeration system. For example at sea level water boils at 212 f. It involves the removal of heat from one region and its deposition to another.

The most commonly used refrigeration machines are the household refrigerator and deep freezer though these machines are available in many other forms. The compressor serves two functions. Understanding the basics is the key to properly plan the maintenance and troubleshoot the marine refrigeration system. 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.

As pressure decreases the change of state temperature also decreases. Sockets provided on deck. 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. The refrigeration system comprises of various components like freon gas compressor condenser evaporator thermostat etc which are all enclosed in a casing.

The pressure temperature relationship is an important principle for refrigeration. 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. It causes refrigerant to flow and is where energy is applied to perform the work of removing heat in the evaporator. The refrigeration plants on merchant vessels play a vital part in carrying refrigerated cargo and provisions for the crew on board.

At 5 000 feet water boils at 202 f. The compressor is the mechanical heart of a refrigeration system. 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. This guide describes the principle and working of marine refrigeration system along with the important components and refrigerants used.
