Marine Refrigeration System Working Principle

It involves the removal of heat from one region and its deposition to another.

Marine refrigeration system working principle.

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. Basic refrigeration system fundamentals the compression cycle. The refrigeration plants on merchant vessels play a vital part in carrying refrigerated cargo and provisions for the crew on board. The compressor serves two functions.

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. The compressor is the mechanical heart of a refrigeration system. At 5 000 feet water boils at 202 f. Individual containers with their own refrigeration plant are connected to the 440 or 220 a c.

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. Understanding the basics is the key to properly plan the maintenance and troubleshoot the marine refrigeration system. This principle is applied in the refrigeration system. It causes refrigerant to flow and is where energy is applied to perform the work of removing heat in the evaporator.

The working principle of a refrigerator and refrigeration in general is very simple. As pressure decreases the change of state temperature also decreases. Sockets provided on deck. The pressure temperature relationship is an important principle for refrigeration.

For example at sea level water boils at 212 f. The most commonly used refrigeration machines are the household refrigerator and deep freezer though these machines are available in many other forms. Systems designed for the cooling of refrigerated containers employ trunkings arranged so that containers stowed in stacks between built in guide rails can be connected to the suction and delivery air ducts of the ship s refrigeration plant by bellows pieces operated. The refrigeration system comprises of various components like freon gas compressor condenser evaporator thermostat etc which are all enclosed in a casing.
