What components change the refrigerant pressure?

Explanation:
The pressure changes in a vapor‑compression refrigerant cycle come from two components: the compressor and the metering device. The compressor raises the refrigerant’s pressure (and temperature) on the high-pressure side so it can reject heat in the condenser. After the condenser, the metering device throttles the refrigerant, dropping its pressure to the low level needed for the evaporator to absorb heat. The condenser and evaporator mainly transfer heat and maintain the two pressure levels rather than actively changing the pressure themselves. So, the key players that change refrigerant pressure are the compressor and the metering device.
