A metering device is a mechanical device that compresses refrigerant gas. True or False?

A metering device does not compress refrigerant gas; instead, it regulates the flow of refrigerant into the evaporator coil in a refrigeration or air conditioning system. The primary function of a metering device is to reduce the pressure of the refrigerant, allowing it to expand and absorb heat from the environment as it changes from a liquid to a gas. This process is crucial for efficient heat exchange and cooling.

The confusion may arise from the role of other components in the refrigeration cycle, such as the compressor, which is specifically designed to compress refrigerant gas. Understanding the distinct functions of each component is essential for comprehending how refrigeration systems operate effectively.
