Summary of English Abbreviations for HVAC Systems (Detailed Version)

1. Classification of Heating Systems by Function HVAC: Heating, Ventilation, and Air Conditioning, the general term for HVAC systems, including heating, ventilation, and air conditioning functions, is widely used to describe the entire system, such as household or commercial HVAC equipment. HR：Heat Recovery， Heat recovery refers to the process of recovering heat from exhaust air to reduce energy waste, commonly found in fresh air systems or industrial waste heat recovery. FH：Floor Heating， Floor heating, usually through water pipes or electric heating film radiation heating, is suitable for residential and office use, especially in cold regions. RHC：Radiant Heating and Cooling， Radiant heating and cooling systems, which use ceilings or floors to regulate temperature, are applied in energy-efficient buildings such as green homes. Ventilation system VAV: Variable Air Volume, a variable air volume system that adjusts the air supply according to demand, is applied to central air conditioning systems for energy conservation and precise temperature control (such as office buildings). CAV：Constant Air Volume， Constant air volume system, operating at a fixed air volume, suitable for small buildings or places that require stable air volume. ERV：Energy Recovery Ventilation， Energy recovery ventilation, which recovers cold/heat through heat exchange, is applied in enclosed buildings such as hospitals and schools. HRV：Heat Recovery Ventilation， Heat recovery ventilation, focusing on heat recovery, suitable for residential buildings in cold regions, reducing heating energy consu

mption. MV：Mechanical Ventilation， Mechanical ventilation, relying on fans to force air exchange, is applied in places with insufficient natural ventilation such as basements and factories. Air conditioning system AC: Air conditioning, generally refers to cooling or heating equipment, applied to household split air conditioners, car air conditioners, etc. DX：Direct Expansion， Direct expansion refrigeration, where the refrigerant directly expands and cools in the evaporator, is used in household air conditioning and multi split systems. HP：Heat Pump， Heat pumps, which achieve heating or cooling through a reverse refrigeration cycle, are used for year-round temperature control, such as air source heat pumps used in residential areas. PAC：Precision Air Conditioning， Precision air conditioning, accurately controlling temperature and humidity, applied in data centers and laboratories.

2. Classification of Local Systems by Coverage: PTAC: Packaged Terminal Air Conditioner, a packaged terminal air conditioner that integrates cooling and heating, used in hotel rooms and single rooms.

. RAC：Room Air Conditioner， Room air conditioner, usually refers to a small independent device, applied to household window or wall mounted air conditioners. SP：Spot Cooling/Heating， Local cooling/heating, only applicable to specific points, used for temporary space or equipment heat dissipation. Central Air Conditioning (CAC): Central Air Conditioning, which serves the entire building through centralized equipment and is applied in shopping malls and office buildings. AHU：Air Handling Unit， The air processing unit, which processes air and distributes it through air ducts, is the core component of central air conditioning. FCU：Fan Coil Uni
