Final answer:
The equipment in which vaporized refrigerant is liquefied by removal of heat is called a condenser. Its primary function is to convert gaseous refrigerant back into liquid. The compressor raises the gas's temperature and pressure, and the evaporator converts liquid refrigerant into gas.
Step-by-step explanation:
A vessel or arrangement of piping or tubing in which vaporized refrigerant is liquefied by removal of heat is known as a condenser. The main function of the condenser in systems like air conditioners and refrigerators is to condense gaseous refrigerant into a liquid form. The compressor in these systems raises the temperature and pressure of the refrigerant gas and forces it into the condenser coils. Within these coils, because the temperature of the gas is higher than the temperature inside the room, heat transfer occurs, leading to the condensation of the gas into a liquid.
The evaporator has a different role; it converts the liquid refrigerant into gas by absorbing heat from the environment. This is part of the reason why the evaporator coil is located in the space that needs to be cooled. Meanwhile, the compressor's job is to compress the refrigerant gas and increase its pressure and temperature, preparing it for the condensation process in the condenser.
