HVAC system components

 Here are the common components of an HVAC (Heating, Ventilation, and Air Conditioning) system:

Heating Components:

1. Furnace (gas, oil, electric)

2. Boiler (hot water, steam)

3. Heat Pump (air-source, ground-source)

4. Radiant Floor Heating

5. Heat Exchanger (coils, tubes)

Cooling Components:

1. Compressor

2. Condenser Coils

3. Evaporator Coils

4. Expansion Valve

5. Refrigerant

Ventilation Components:

1. Fans (supply, exhaust, return)

2. Vents (intake, exhaust, transfer)

3. Ductwork (supply, return, exhaust)

4. Air Filters (particulate, gas, odor)

5. Controls (thermostats, humidistats, sensors)

Air Handling Components:

1. Air Handler Unit (AHU)

2. Fan Coil Unit (FCU)

3. Blowers

4. Coils (heating, cooling)

5. Plenums

Control Components:

1. Thermostats

2. Humidistats

3. Sensors (temperature, humidity, pressure)

4. Controllers (PID, PLC)

5. Valves (control, isolation)

Other Components:

1. Pumps (circulating, condensate)

2. Motors (fan, compressor)

3. Drives (variable speed)

4. Insulation

5. Duct Sealants

Note: The specific components may vary depending on the type of HVAC system and its application.
