WebThe refrigerant comes into the compressor as a low-pressure gas, it is compressed and then moves out of the compressor as a high-pressure gas. The gas then flows to the condenser. Here the gas condenses to a liquid, and gives off its heat to the outside air. The liquid then moves to the expansion valve under high pressure. WebA refrigeration cycle is a closed system with constant total fluid mass, apart from unwanted leakages. Like any closed thermodynamic system, the mass of the fluid stored in it has a direct influence on its state, described by state variables such as pressure and temperature. Just like a bicycle tire, the pressure increases when more mass is added.
