This EdrawMax diagram presents a detailed view of a Central Air-Conditioning System, illustrating the essential components and their interconnections. The system includes a 'Fan' for air distribution, a 'Cooling Tower' for heat dissipation, a 'Main Freezing Engine' typically used for cooling the refrigerant, 'Coils' and 'Coil Fans' for air treatment and circulation within the premises. Additionally, the system incorporates a 'Freezing Pump' to facilitate the refrigerant flow and a 'Compressor Unit' to maintain the refrigerant pressure. This schematic is invaluable for HVAC professionals, students, and anyone interested in understanding the operational mechanics of large-scale air conditioning systems.
