How does the compressor affect the refrigerant temperature and pressure?

The compressor plays a crucial role in the refrigeration cycle by increasing the pressure and temperature of the refrigerant. When the refrigerant enters the compressor as a low-pressure gas, the compressor compresses this gas to a higher pressure. The compression process reduces the volume of the refrigerant and increases its pressure.

As the refrigerant is compressed, its temperature rises as well, due to the principles of thermodynamics, where compressing a gas increases its internal energy, and therefore its temperature. This is essential for the refrigeration cycle as it prepares the refrigerant to release heat in the condenser, allowing the system to work efficiently and maintain its cooling capabilities.

Understanding this process is fundamental to the operation of refrigerants in air conditioning and refrigeration systems, making it clear why the correct answer reflects that both the temperature and pressure are increased by the compressor’s function.
