The Refrigeration Cycle

The refrigeration process entails a series of four stages aimed at maintaining the optimal cool temperature within a wine cellar.

1. Initiating the cycle, the refrigerant enters the Compressor, where it undergoes compression and pressurization. Prior to entering the compressor, the refrigerant exists as a hot gas.
2. Subsequently, the compressor acts as both a pump and a conduit, propelling the refrigerant toward the Condenser. Here, the vapor is condensed into liquid form, simultaneously dissipating some of the heat.
3. From the condenser, the refrigerant advances to the Expansion Valve, where it undergoes expansion, resulting in a reduction of pressure and heat. Exiting the expansion valve, the refrigerant emerges cold, having shed excess pressure.
4. The refrigerant then enters the Evaporator Coil in liquid form, facilitating the exchange of heat and inducing cooling. Notably, it is the evaporator coil that effectively chills the interior of the wine cellar.
5. As the gas cools and absorbs heat, it transitions back into a gaseous state. This gas is subsequently reintroduced into the Compressor, initiating the repetition of the cycle.
