• Evaporator Coil: This is where the refrigerant absorbs heat from the indoor air, cooling it down. The coil is typically made of copper or aluminum and has fins to increase its surface area for heat exchange.
• Blower Fan: The blower fan circulates air across the evaporator coil and distributes the cooled air throughout the room or building.
• Air Filter: The air filter removes dust, pollen, and other contaminants from the air before it passes through the evaporator coil. This helps to keep the coil clean and maintain good air quality.
• Drain Pan: The drain pan collects condensation that forms on the evaporator coil. The water is then drained away through a drain line.
• Control Panel: The control panel houses the electrical components that control the operation of the AC unit, including the thermostat, fan speed settings, and other functions.
• Expansion Valve/Metering Device: This component regulates the flow of refrigerant into the evaporator coil, ensuring proper cooling.
