pressure in a refrigeration system is changed in the
In a refrigeration system, pressure is changed primarily at the compressor and the expansion valve. The compressor increases the pressure of the refrigerant vapor, raising its temperature and allowing it to release heat in the condenser. After the refrigerant condenses into a liquid, it passes through the expansion valve, where pressure is drastically reduced, allowing it to evaporate and absorb heat in the evaporator. This cycle of pressure changes is crucial for the refrigeration process.
The pressure on the low pressure side of a refrigeration system is determined by the refrigerant's temperature and the system's design. As the refrigerant absorbs heat in the evaporator, it vaporizes and its pressure decreases. The size of the evaporator, the amount of refrigerant flowing through it, and the efficiency of the system also affect the pressure on the low side.
Yes, in a refrigeration system, the refrigerant changes state from a high-pressure gas to a high-pressure liquid in the condenser, and then from a low-pressure liquid to a low-pressure gas in the evaporator. These state changes are crucial for the refrigeration cycle to operate efficiently.
In refrigeration, the symbol ( P_2 ) typically represents the pressure at the discharge or high-pressure side of the refrigerant system, specifically after the compressor. It is crucial for determining the efficiency and performance of the refrigeration cycle, as it influences the condensation process and overall system pressure. Maintaining the correct ( P_2 ) is essential for optimal operation and system reliability.
The pressure in a refrigeration system changes in the compressor, condenser, expansion valve, and evaporator. In the compressor, the pressure increases, while in the condenser, it remains high before decreasing in the expansion valve and evaporator.

Pressure-temperature charts in refrigeration are used to determine the relationship between the pressure of a refrigerant and its corresponding temperature in a specific system. By referencing these charts, technicians can accurately diagnose issues, set proper system pressures, and troubleshoot problems. This helps ensure the system operates efficiently and effectively.
