<h3>
What is refrigeration system?</h3>
Refrigeration systems are crucial processes in business and domestic applications because they provide cooling or maintain a specific room temperature. A refrigeration cycle consists of heat exchange, compression, and expansion with a refrigerant flowing through the cycle's units.
The refrigerants are chemical substances with thermodynamic properties that are ideal for the functioning of a refrigeration cycle. They are often tiny molecules with lower than normal boiling points (usually less than 273 K). However, other safety qualities (such as flammability or auto-ignition temperature) and environmental impact (such as ozone depletion or global warming) influence their selection.
