It is, however, important to note that Air conditioning applications are not just for residential and human comfort, there are other industrial processes where cool temperatures are required and therefore Air conditioning is utilized examples are; Nuclear facilities where temperature is
kept at 20◦c until a reaction occurs, Mines where temperature is cooled from 55◦c to a more tolerable 28 C, Processes where extremely high levels of air cleanliness are required for the success of the process, Data processing centers, Cold room ( For meat storage) .e.t.c.
