Final answer:
The component that directly follows the condenser in a refrigeration system with a TXV is the metering device. It regulates the pressure of the refrigerant before it enters the evaporator.
Step-by-step explanation:
In a refrigeration system with a TXV (Thermostatic Expansion Valve) or another type of throttling device, the component directly following the condenser is the metering device.
The refrigeration cycle consists of four main components: the condenser, the expansion valve or metering device, the evaporator, and the compressor. After the high-pressure and high-temperature refrigerant gas releases its heat and condenses to a liquid in the condenser, it flows through the metering device.
This device reduces the refrigerant pressure as it flows into the evaporator, which facilitates the refrigeration cycle's cooling effect as the refrigerant absorbs heat and evaporates.
