Replacement of Air-Conditioning units to maintain a constant temperature of 20^oC

OVERVIEW
To ensure that a steady temperature of 20°C was maintained, two additional package type units as well as the replacement of the two existing units was required.

SOLUTION
New SKM 20TR units were selected with a modification to the existing control panel so that two units would be functioning while the other two were on standby. In the event of any one of the working units malfunctioning one of the standby units would automatically start up to ensure that the temperature was maintained at a constant 20°C. All four units are timer set to work in every 12 hour cycle with only two units running at any given time. The panel was also set to ensure that a manual override would not enable a third unit to be started up.

RESULT
The system is functioning smoothly and maintaining the steady temperature as per the client’s requirement.

CONCLUSION
The solution provided maintained the temperature without all four units having to function at the same time. The system was also designed so that there was no requirement for the units to be switched over manually every 12 hours.
