This session will: • Give you control concepts that will inform you to choose wisely • Enable you with the vocabulary to ask for what you want in an HVAC control system
HVAC controls history: • Manual Temperature Control • Automatic Temperature Control • Building Management Systems • Energy Management Systems
Manual Temperature Control • Simple, effective, not efficient • Huge temperature swings • Requires 24 hr attention • Humidity and air quality is • is not considered
Automatic Temperature Control • Became possible with popularity • of central heating and cooling • Mechanized thermal sources • Sensors for temperature • monitoring and control
How to provide comfort to larger environments with a variety of needs and loads?
Building Automation Systems (BAS) • Co-ordinates the many • components in these systems • Saves energy by being more • responsive to changes in load, • usage patterns, and adjusting to • outside environment
Energy Management Systems (EMS) • Include all the features of the previous • systems • Added sensing devices that report to a • front-end computer • Sensors that monitor conditions inside • and outside the building
Energy Management Systems (EMS) • Reporting capabilities • Remote management over • the internet • Alerting by email and text • Can adjust the system for • maximum efficiency • Can manage elements like • geothermal and solar • sources
