How to Manage a Heat Transfer in the Headend

Headend devices comprise the computer, operating systems and hardware that manage a facility. Though there are almost innumerable systems and programs that control heat transfers, there are several steps administrators can take to attempt managing their devices correctly. Proper maintenance of heat-transfer hardware should be a requirement of the facility schedule, and if any irregular or poor transfers are noted, administrators should first clean transfer coil tubes and replace degraded equipment.

Instructions

- 1
  Open the facility's building automation system, BAS, or energy management system, EMS, program at the headend. This program will contain all of the previous heat exchange logs and statistical data. Make sure the program is functional and connected to the building's facility management system, FMS, before attempting a heat exchange, so that all appropriate data will be logged by the computer.
- 2
  Consult your FMS to begin the heat exchange operation. Whether activation controls on your heat exchange system are located on the headend system, or are manual controls on the HVAC panel or a separate panel entirely, a facility's FMS is typically the first place heat exchanges are activated. Attempt to turn on the heat exchange system from this panel, and if the appropriate switch is found, check your heat exchange hardware to confirm it is operational.
- 3
  Inspect your heat exchange hardware if it is not operational. Buildup of hard metals on the coils, frayed wires, or a damp atmosphere around its microprocessor are all indicators that improper maintenance or environmental conditions may have caused a malfunction. This may be solved by cleaning the coils and correcting and replacing the wires or microprocessor. Contact the manufacturer of the heat exchange if these steps produce no improvement, or no technician is available to make the repairs.
- 4
  Adjust a functional heat exchange as necessary from the headend or from the access panel that functioned to begin the heat exchange. Double-check the BAS to make sure the appropriate measurements are being recorded.
- 5
  Disable the heat exchange by the same process as it was begun, taking care to inspect the heat exchange hardware and perform proper maintenance once it has cooled.
