✌☝❣❣❣❣ooya!....is the mechanism in ac and refrigerator same or different
Answers
Refrigeration and air conditioning works on the same principle, the difference is in the application. Air conditioning refers to the manipulation of air temperature, humidity and air quality in space where human or machines are the main occupants. Besides air temperature, humidity and air quality, acoustic performance, air distribution and airflow velocity are also parameters of concern in air conditioning. There is also a common misconception that air conditioning must be about cooling or heating, which is not true. There are applications where only the moisture content and air quality are parameters of concern without a specific target temperature requirement. Air conditioning also need not be in a confined space, e.g natural ventilation is under the branch of air conditioning. Mechanical cooling is also not always required in air conditioning depending on the requirement, for example free cooling and simple ventilation. Its application is mostly in human comfort, equipment cooling, artifacts preservation, infections control or industrial environment such as clean room.
Refrigeration on the other hand, is all about cooling, and it must be in confined spaces. Temperature range is usually much lower than air conditioning, from 5C all the way down to -70C in ultra lower temperature freezers. Humidity is of less concern, because air is normally fully saturated at this temperature, but coil freezing will be of concern at sub zero temperature. Also there is no requirement of air circulation, no human presence and therefore less concern on air quality. Mechanical cooling is almost always required to achieve such low temperature, unless you are in the arctic. It’s application is mostlt in food preservation, industrial processes and scientific research.

Hey User!
How are you?
Your Answer!
Both air conditioning and refrigeration units depend on converting liquid to gas in the cooling process, but the manner in which they achieve this is different for each system. ... Refrigeration units, on the other hand, cycle HFC into a low-pressure chamber designed to boil the gas.
A major difference between refrigeration and air conditioning is the point of supply for the gases. ... HFC-134a is the sole gas used as a coolant in refrigeration systems. Air conditioning systems use built-in chemicals, but also air from the room or rooms being heated.
Hope This Helps U a lot!
