Refrigerant Cycle Process: Air conditioners all the same cycle of Compression, Condensation, Expansion, and Evaporation in a closed circuit, in order to reuse the refrigeration within the system. The cycle flow is as follows. 1. It Begins at the compressor, the refrigerant comes into the compressor as a low-pressure gas, it is then compressed and moves out of the compressor as a high-pressure gas. 2. The gas then flows to the condenser where it is condenses to a liquid. This state change produces heat which is expelled to the external ai​r. 3. The liquid then moves from the condenser to the expansion valve under high pressure. This valve restricts the flow of the fluid, and removes pressure as it leaves the expansion valve. 4. Low pressure liquid refrigerant moves to the evaporator. Here heat from the air in the room is absorbed and this causes the liquid to turn into a gas. 5. The low-pressure, high temperature gas from the evaporator moves to the compressor, at which the cycle ends and then begins again in a repeated way.
