What is the relationship of absolute pressure on the low side to absolute pressure on the high side called?

• A. Compression ratio
• B. Pressure differential
• C. Temperature ratio
• D. Heat transfer ratio

Answer: (A)

The correct term for the relationship of absolute pressure on the low side to absolute pressure on the high side is the compression ratio. This is a vital concept in refrigeration and HVAC systems as it defines how much the refrigerant gas is compressed from the low-pressure (low side) evaporator to the high-pressure (high side) condenser. The compression ratio is calculated by dividing the absolute pressure on the high side by the absolute pressure on the low side. A higher compression ratio indicates a greater difference in pressure which usually reflects higher efficiency in the operation of the compressor, although it can also contribute to additional wear and tear. Understanding this relationship is crucial for professionals in the field since it influences the overall performance and energy consumption of the refrigeration system, and it provides insights into the system's operational efficiency.
