What component is typically used to restore liquid refrigerant from the gaseous state in the system?

The condenser is the component in a refrigeration system that is used to restore liquid refrigerant from the gaseous state. This process occurs after the refrigerant has absorbed heat and changed into a gas in the evaporator. As the gaseous refrigerant enters the condenser, it is cooled by air or water, which allows it to release heat to the environment. This cooling causes the refrigerant to condense, turning it back into a liquid state as it releases its latent heat.

The important function of the condenser is crucial to the overall efficiency of the refrigeration cycle, as it prepares the refrigerant for the next stage of the process, where it will once again be used for heat absorption in the evaporator. Other components like the evaporator, TXV (Thermal Expansion Valve), and compressor each have different roles; the evaporator absorbs heat, the TXV controls the flow of refrigerant based on temperature, and the compressor moves the refrigerant through the system but does not directly engage in the phase change from gas back to liquid.
