Evaporator
An evaporator is a crucial component in heating, ventilation, and air conditioning (HVAC) systems that helps create cool air. Think of it like a radiator working in reverse - instead of giving off heat, it absorbs heat from the air inside a building. When HVAC technicians mention evaporators in their resumes, they're referring to their experience with installing, maintaining, or repairing this essential part of air conditioning systems. You might also hear it called a "cooling coil" or "evaporator coil" because it contains special refrigerant chemicals that absorb heat while flowing through a coiled tube system.
