The core structural characteristics of a standard air conditioner can be categorized into four main systems, featuring a compact overall design with clearly defined functional roles:
Refrigeration System
Serving as the core of the unit, this system comprises a compressor, condenser, evaporator, and expansion valve. It achieves cooling or heating effects by facilitating heat transfer through the phase-change cycle of the refrigerant.
Airflow System
Consisting of cross-flow or axial fans, filters, and air ducts, this system accelerates heat exchange between the air and the heat exchanger, ensuring the treated air is evenly distributed throughout the indoor space.
Electrical Control System
Comprising the control board, temperature sensors, and various protective components, this system monitors environmental parameters in real-time and automatically adjusts the unit's operation to ensure precise temperature control and safety.
Casing and Connection Structure
Split-system air conditioners feature separate indoor and outdoor units connected by copper piping, electrical wiring, and drainage lines; this layout offers flexibility while balancing aesthetics with heat dissipation efficiency.
