The relationship between low-side absolute pressure and high-side absolute pressure is known as:

The relationship between low-side absolute pressure and high-side absolute pressure is referred to as the compression ratio. This concept is crucial in refrigeration and air conditioning systems, as it represents the efficiency of the compressor.

The compression ratio is calculated by dividing the absolute pressure of the high side by that of the low side. A higher compression ratio can indicate that the system is working under higher pressure conditions on the high side, which may affect the overall performance, energy consumption, and capacity of the system. Understanding the compression ratio helps technicians evaluate and troubleshoot the performance of refrigerant systems, as it can influence factors like discharge temperature and efficiency.

The other terms, such as clearance pocket, compressor capacity, and two-stage application, relate to different aspects of refrigeration systems. Clearance pocket refers to a small space in the compressor that can retain refrigerant, which may contribute to inefficiencies but does not describe the pressure relationship. Compressor capacity indicates how much refrigerant a compressor can handle but is not specifically about the relationship between high-side and low-side pressure. Two-stage applications describe systems designed to operate with two compressors or stages to enhance efficiency, rather than specifying pressure relationships.
