The Mechanical system of a building – heating, ventilation and air conditioning – provides indoor environmental comfort to occupants by maintaining thermal comfort and acceptable indoor air quality. Mechanical systems provide ventilation, reduce air infiltration, and maintain pressure relationships between spaces. The design, installation, and control systems of these functions are often integrated into one or more systems.
Service designers and mechanical engineers analyze, design and specify the mechanical system installation and modification requirements. Cooling, heating and ventilation of the building interior have the following components:
Cooling Equipment. Chillers, Cooling Towers, Condensers, Pumps, Packaged Equipment
Heating Equipment. Boilers, Furnaces, pumps, chimneys, flues and vent piping
Energy Source. Oil, Gas, Electric, Solar*, another alternative fuel, or a combination
Air Handling Fans
Air Handling Equipment. Heating and Cooling Water Coils, Refrigerant Coils
Ductwork. Insulation and support
Air Outlets. Grills and louvers
Temperature. Air and water flow control equipment
Air Volume Controlling Devices
Thermostats. Aqua stats, humidity controllers
**Refer to specific guidelines for Boiler/ Burner/ Fuel/Chimneys, and Solar Energy source installations*
