• Compressor: The heart of the AC unit, responsible for compressing the refrigerant and circulating it throughout the system.
• Condenser: Located outside, the condenser releases heat from the refrigerant. It includes a fan to enhance heat dissipation.
• Evaporator: Located inside, the evaporator absorbs heat from the indoor air, cooling the space.
• Refrigerant: A special fluid that absorbs and releases heat, circulating throughout the system.
• Fan Motors: These motors drive the fans in the condenser and evaporator units, facilitating air circulation.
• Electrical Components: This includes the wiring, capacitors, relays, contactors, transformers, and control boards that power and control the AC system.
• Thermostat: The control center that senses the room temperature and signals the AC unit to turn on or off.
