Which part of the refrigeration system is responsible for raising the vapor pressure?

• A. The evaporator
• B. The condenser
• C. The compressor
• D. The expansion valve

Answer: (C)

The component responsible for raising the vapor pressure in a refrigeration system is the compressor. The compressor's primary role is to take in low-pressure vapor refrigerant from the evaporator and compress it, which increases both the pressure and temperature of the refrigerant. This process transforms the refrigerant from a gas at low pressure into a high-pressure gas, making it suitable for entering the condenser. Understanding the function of the compressor is crucial because it directly influences the efficiency of the refrigeration cycle. By raising the vapor pressure, the compressor enables the refrigerant to effectively release heat in the condenser and allows the cycle to continue. The other components have distinct roles where the evaporator is involved in absorbing heat and lowering the refrigerant pressure, the condenser is focused on releasing heat and lowering the refrigerant’s temperature while maintaining or decreasing its pressure, and the expansion valve is responsible for dropping the pressure of the refrigerant entering the evaporator. Thus, the compressor stands out as the pivotal element in increasing vapor pressure in the system.
