Which statement accurately describes the relationship between temperature and pressure in refrigeration?

The accurate description of the relationship between temperature and pressure in refrigeration is that as pressure increases, temperature also increases in a sealed system. This principle is grounded in the gas laws, particularly in the context of the ideal gas law, which states that for a given amount of gas at a constant volume, there is a direct correlation between temperature and pressure.

In a refrigeration system, when a refrigerant is compressed, its pressure increases, and as a result, the temperature of the refrigerant also rises. This is essential for the operation of refrigeration cycles, where the refrigerant must first be compressed (increasing pressure and temperature) before it can release heat and condense in the condenser section.

This relationship is critical for understanding how refrigeration systems function, including how the compressor, condenser, expansion valve, and evaporator work together. It highlights why managing pressure and temperature is crucial for efficient refrigeration operation. The other statements present inaccurate concepts that do not align with thermodynamic principles fundamental to understanding refrigeration cycles.
