Refrigeration is a process of moving heat from one place to another, and this has had a profound effect on industry, lifestyle, agriculture and residential patterns. The concept of food preservation comes from the ancient Roman and Chinese empires. However, the technology of refrigerators has evolved rapidly in the last century, from snow harvesting to temperature-controlled train cars.

·    In the refineries of oil, chemical plants, and petrochemical plants, the refrigerator is used to keep certain processes at their required low temperatures, such as the alkylation of butanes and butane to produce a high octane component of fuel.

·     Metalworkers use the refrigerator to silence metal and cutting materials. In the case of transport of heat-resistant food and other items by truck, train, plane and sea, refrigeration is a must.

·    All refrigeration methods can be classified as non-cyclic, cyclic, thermoelectric and magnetic.

·   The refrigerator cycle describes the changes that take place in the refrigerator as it absorbs and rejects heat as we move around in the refrigerator.

· It is also used in the heating, ventilation, and ventilation work, in describing the ‘process’ of refrigeration flow by the HVAC & R unit - whether it is a packaged or isolated system.

Refrigeration the process of removing heat from a confined space or object for the purpose of lowering the temperature. In industrialized nations and affluent lands in developing lands, refrigerators are primarily used to store food at lower temperatures, thus preventing the destructive action of bacteria, yeast, and fungi. Many perishable products can be frozen, allowing them to be stored for months and even years without the slightest loss of nutrients or taste or appearance. Air-conditioning, the use of refrigeration for comfortable cooling, is also widespread in developed countries.

The basic components of a modern vapor pressure system are a compressor; condenser; expansion device, which may be a valve, capillary tube, engine, or turbine; and evaporator. The gas cooler is first compressed, usually with a piston, and then pushed through a tube into the condenser. In a condenser, a rotating tube containing vapor passes through a circulating air or bath water, which releases the heat energy of the compressed gas. Cool vapor is transferred through an expansion valve to the lowest pressure point; as the vapor grows, it absorbs its expansion energy into the surrounding or central contacts. Evaporators can either cool the space directly by allowing the vapor to come in contact with the cooling system, or they can do this indirectly — that is, by cooling the second object such as water. In most home refrigerators, the coil containing the evaporator comes in direct contact with the air in the dining area. At the end of the process, the hot gas is drawn into the compressor.

In simple terms, the goal of a refrigerator cycle is to absorb heat and resist heat. As any trainer will tell you (emphatically), you can’t get cold, you can just remove the heat. The refrigerator cycle, sometimes called the heat pump cycle, is a way of moving heat away from the area you want to cool down. This is achieved by controlling the pressure of an active refrigerator (air, water, synthetic refrigerators, etc.) through a pressure and expansion cycle.

 

Four major characteristics of the refrigeration basic cycle:

1. Compressor.

2. Condenser.

3. Extension tool.

4. Evaporator.

The refrigerator system requires certain means of connecting key components - evaporator, compressor, condenser, and meter - just as the roads connect communities. Tubes or "lines" make the system perfect so that the refrigerator does not get into the atmosphere. Some systems will have a receiver immediately after the condenser and before the measuring device, where the refrigerator is stored until it is needed to remove heat from the evaporator.
