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 HVAC 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 function of the refrigeration cycle is to remove unwanted heat from one place and transfer it to another. To achieve this, the refrigerator is pumped through a closed refrigerator system. If the system was not shut down, it would use the refrigerator to disperse it to the surrounding media; because it is closed, the same refrigerator is used repeatedly, as it goes through the cycle releasing some heat and releasing it. Closed cycle serves other purposes as well; keeps the refrigerator free of contamination and controls its flow, as it is a liquid in some parts of the cycle and gas or vapor in other stages.

Let’s take a look at what happens in a simple refrigerator cycle, and in the big things involved. Two different pressures exist in the cycle - evaporation or low pressure "on the lower side," and reduction, or greater pressure, "on the upper side." These compressors are divided into two separating points: one is a measuring instrument in which the flow of the refrigerator is controlled, and the other is a compressor, in which the vapor is compressed. A device for measuring the point at which we will begin the cycle cycle. This could be a heat exchanger valve, a capillary tube, or any other refrigerator flow control device in the evaporator, or a coil coil, such as a low-pressure refrigerator, and a low-temperature refrigerator. The growing refrigerator evaporates (changes position) as it passes through the evaporator, where it removes heat from the object or area where the evaporator is located.

The heat will move from a warm object to a cool evaporator to evaporate the refrigerator inside the system, causing the refrigerator to “boil” and evaporate, turning into steam. This is similar to the change that occurs when a bucket of water boils on a stove and the water turns to steam, except that the refrigerator boils down to a much lower temperature. Now this low-pressure, low-temperature vapor is drawn into a compressor where it is compressed into a high-temperature, high-pressure vapor. The compressor discharges it into the condenser, so that it can stop the heat it has taken from the evaporator. Refrigeration vapor is at a higher temperature than air passing through a condenser (a cool type of air); or water passing through a condenser (water-cooled type); therefore that is transferred to the warm smoke of the refrigerator to cool air or water.
