Types of Air Conditioning Systems:


1. Window Unit

2. Split System

3. Central Air Conditioning

4. Evaporative Cooling (Swamp Cooler)

5. Heat Pump


Air Conditioning Components:


1. Compressor

2. Condenser Coils

3. Evaporator Coils

4. Expansion Valve

5. Refrigerant


Air Conditioning Processes:


1. Cooling Cycle (refrigeration cycle)

2. Dehumidification

3. Air Filtration


Air Conditioning Efficiency:


1. SEER (Seasonal Energy Efficiency Ratio)

2. EER (Energy Efficiency Ratio)

3. HSPF (Heating Seasonal Performance Factor)


Air Conditioning Maintenance:


1. Filter Cleaning/Replacement

2. Coil Cleaning

3. Refrigerant Leaks Detection

4. Thermostat Calibration


Air Conditioning Benefits:


1. Cooling and Dehumidification

2. Improved Indoor Air Quality (IAQ)

3. Enhanced Occupant Comfort and Productivity

4. Reduced Heat-Related Illnesses


This is a brief overview of air conditioning systems and components.
