Refrigeration Advantages And Disadvantages

2.0 SUMMARY
Leakages in industries have become a very common mishap that has been going on despite the strong materials being use to enclose the refrigerant. As the refrigerant costs continue to rise and a government regulation becomes increasingly restrictive, employing an effective refrigerant leak detection system is more important than ever. Nowadays commercial and industrial refrigeration and air conditioning systems leak too much refrigerant, which can come up to 30% of the charge during a year are not uncommon. The cause of leakages can come from many scenarios and for that reason many different methods have been made to detect those small leakages to avoid any more mishap to evolve. There are many types of methods which specialises in detecting leakage in a system, but a single leak detection method that locates every leak in every possible situation simply does not exist.

2.1.1 Refrigeration
What is refrigeration?
Refrigeration can be defined as a process of removal of heat from a space where heat it is unwanted and transferring it at the same to the surrounding atmosphere. The temperature in a space is to be maintained at a lower temperature than the temperature of the surrounding environment. To produce refrigerant effect, a substance that needed to be cooled needs to be exposed to a cooler environment. The heat in the material will then flow from a warmer material to a colder or cooler material. Mechanical refrigeration is a mechanical
