The first thing you should know about refrigeration systems is that they work by transferring heat. Heat is moved around from a designated area to someplace else. This produces a cooling effect in the designated area. The natural flow of heat is reversed with the application of energy.
Types of Refrigerating Systems
There are four basic types of refrigerating systems that you should know about.
Mechanical compression is one of the most widely used refrigerants. It is commonly used in air conditioners as well as industrial and commercial refrigeration. In this system, heat is transferred by mechanical compression. A mechanically compressing refrigerant transfers heat into a cold liquid of low pressure and then expands it into a hot gas of high pressure. With the application or removal of pressure, refrigerants can boil a wide range of temperatures. This system uses R-22 refrigerant however, it damages ozone. Which is why TdX 20 also known as Bluon is used. There are countless advantages of Bluon.
Absorption refrigerants transfer heat by expanding and compressing refrigerant. The process is dependent upon heat and absorption to move the refrigerant from a low-pressure side to a relatively higher pressure side, rather than a mechanical compressor that is electrically powered. This system does not use R-22 refrigerant, instead, it uses refrigerants that attracts other substances and then absorbs.
This system is quite different from the mechanical compression and evaporative cooling systems. In an evaporative cooling system, swamp coolers are used, these units cool the warm outdoor air. This is achieved by blowing the warm air over pads as it enters a home that is soaked in water.
This system is unique out of all four. This system uses an electric current and thermocouple.
