As the pressure increases in a sealed system, what happens to the temperature?

In a sealed refrigeration system, as the pressure increases, the temperature also increases. This relationship is described by the ideal gas law, which states that if the volume is held constant, an increase in pressure will lead to an increase in temperature. This principle is fundamental in thermodynamics and applies to various refrigeration cycles.

When a refrigerant or gas is compressed, work is done on that gas, which results in an increase in both its pressure and temperature. This is because compressing the gas reduces its volume, leading to more frequent collisions between the molecules, which translates into a rise in temperature.

Understanding this relationship is crucial for HVAC technicians and professionals working with refrigeration systems. It helps them to predict system behavior under different operating conditions and ensures that they can manage thermal dynamics effectively within the equipment they service.
