What equipment is used in HVAC?

In an HVAC (Heating, Ventilation, and Air Conditioning) system, various types of equipment are used to regulate and maintain the desired indoor environment. Here is a detailed list of key HVAC equipment and their functions:

1. Heating Equipment

Furnace

• Description: Heats air through combustion of fuel (gas, oil) or electricity.
• Components: Burner, heat exchanger, blower, flue.
• Function: Transfers heat to air and distributes it through ductwork.

Boiler

• Description: Heats water for heating systems.
• Components: Burner, heat exchanger, pumps, expansion tank.
• Function: Provides hot water or steam for radiators or radiant floor heating.

Heat Pump

• Description: Transfers heat from outdoors to indoors.
• Components: Compressor, condenser, evaporator, expansion valve.
• Function: Works in reverse to provide cooling in summer.

2. Cooling Equipment

Air Conditioner

• Description: Removes heat from indoor air to cool the space.
• Components: Compressor, condenser coil, evaporator coil, expansion valve, refrigerant.
• Function: Absorbs indoor heat and releases it outdoors.

Chiller

• Description: Produces chilled water for air conditioning.
• Components: Compressor, evaporator, condenser, expansion valve, water pump.
• Function: Provides cooling for large buildings by circulating chilled water.

3. Ventilation Equipment

Air Handling Unit (AHU)

• Description: Regulates and circulates air.
• Components: Fan, filter, heating and cooling coils, dampers, humidifier.
• Function: Mixes fresh and recirculated air, conditions it, and distributes it.

Rooftop Unit (RTU)

• Description: Self-contained unit located on the roof.
• Components: Similar to AHU with heating and cooling components.
• Function: Conditions and distributes air for commercial spaces.

Energy Recovery Ventilator (ERV)

• Description: Transfers heat and moisture between incoming and outgoing air.
• Components: Heat exchanger, fans, filters.
• Function: Improves energy efficiency by recovering energy from exhaust air.

Exhaust Fans

• Description: Removes stale air.
• Components: Motor, fan blades, housing, vent.
• Function: Ventilates areas like kitchens and bathrooms.

4. Humidity Control Equipment

Humidifier

• Description: Adds moisture to the air.
• Components: Water supply, evaporative pad, steam generator, fan.
• Function: Maintains indoor humidity to prevent dryness.

Dehumidifier

• Description: Removes moisture from the air.
• Components: Compressor, evaporator coil, condenser coil, water collection tank.
• Function: Reduces humidity to prevent mold and discomfort.

5. Air Quality Equipment

Filters

• Description: Removes particulates from the air.
• Types: Fiberglass, pleated, HEPA, activated carbon.
• Function: Improves air quality by trapping dust and pollutants.

Air Purifier

• Description: Cleans the air by removing pollutants.
• Components: Filters, UV lights, ionizers, fans.
• Function: Reduces airborne contaminants and allergens.

6. Ductwork and Distribution

Ducts

• Description: Channels for air distribution.
• Types: Flexible, rigid, semi-rigid.
• Function: Distributes conditioned air throughout the building.

Diffusers and Grilles

• Description: End points of the duct system.
• Function: Evenly distribute or collect air in rooms.

7. Control Systems

Thermostats

• Description: Regulates temperature settings.
• Types: Mechanical, digital, programmable, smart.
• Function: Allows users to set and maintain desired temperatures.

Building Management System (BMS)

• Description: Centralized control system.
• Components: Sensors, controllers, software.
• Function: Optimizes energy usage and maintains comfort.

8. Additional Equipment

Heat Exchanger

• Description: Transfers heat between fluids.
• Types: Plate, shell and tube, finned tube.
• Function: Improves efficiency by recovering heat.

Compressor

• Description: Increases refrigerant pressure.
• Function: Essential for refrigeration and air conditioning systems.

Expansion Valve

• Description: Regulates refrigerant flow.
• Function: Controls the refrigeration cycle.
