Heating and Air Conditioning

Newer residence halls and apartment buildings at Georgia Tech are equipped with four pipe HVAC systems that are controlled automatically. Normally, during moderate conditions, both heated water and chilled water is available to condition the spaces in these buildings. When the outside air temperature rises above 55 degrees, the production of heated water is reduced. Likewise, when the air temperature falls below 65 degrees, chilled water for air conditioning is reduced. This automated system of controls is designed to conserve energy consumption within the buildings. This system allows occupants to switch between heating and air conditioning at their discretion.

Our older residence halls and apartments that have the two-pipe system will be transitioned or started based upon outside air temperature. When the outside air temperature rises above 55 degrees, the production of heated water is reduced. Likewise, when the air temperature falls below 65 degrees, chilled water for air conditioning is reduced.

The converse will apply to all two-pipe systems as the A/C season nears it end and we prepare for the Fall heating season. Note: At between 50-55 degrees outside temperature, the above transition, which involves tempering the water temperature that circulates through the system, begins automatically. The Metasys program installed allows the two-pipe system to mimic the newer four-pipe systems and provides greater creature comfort. Cloudman and Harrison are the only two-pipe systems that require manual conversion from A\C to Heating.

Tips for insuring proper operation of Heating/Air Conditioning units

1. Keep area below and in front of unit clear of obstructions. This will insure that air may flow through the unit and make it easier to access if problems arise.
2. Do not place any items on top of units or attach any items to the circulation grills within your room, which may impede air circulation. This will ensure that air may flow fully through the room.
3. Periodic filter changes are scheduled for all buildings on campus to ensure the proper functioning of the unit. Please assist this operation in allowing access to the unit during the buildings scheduled time period. Housing Staff will be posting information 1 week in advance of the time they will be doing the filter change.
4. During periods of moderate weather, you may want to open your windows. Be advised that your heating and air conditioning units will not be as effective if your windows are opened. This is particularly true in warm weather during conditions of high humidity. Opening your windows in the �cool of the morning� will flood your room with moisture saturated air which is difficult for your HVAC system to remove. As a result, it will take several hours from the time you close your window (after it starts getting warm) for your air conditioning unit to return your room to a normal comfort level.
5. The Department does not permit installation of supplemental window air conditioning units in residence halls and suites due to electric load constraints.
