Energy Saving Tip
Clean
condenser coils
Dirt, Grime and Pollution build up
on the outdoor condenser. Regular cleaning reduces the power consumption and improves
performance.
Correct
air flow
Do not block supply or return air grills.
Air current should not blow over the thermostat or short cycle back into the return
air.
Short
cycling Condenser Air
Most condenser discharge
air vertically and draw air into the bottom or sides. Overhangs, roofs, fences
or shrubs can block air discharge and be drawn back into the condenser. This increases
the compressor amperage and temperature.
Fan,
Belt,& Pulley
Belt driven systems require occasionally
adjustment or fan belt replacement. Loose fan belts will slip on the motor pulley.
Wearing the V groove of the pulley wall and slow the fan and reduce the air flow.
Condenser
Fan Control
Condensers are design to work at
95F or higher. In cooler temperature below 70F, the mechanical refrigeration will
lose efficiency. By turning off condenser fan or reducing the speed of the fan
keeps the condenser pressure steady.
AC
Economizers
When the outdoor air is below the room
temperature it can be used for cooling. Why pay for the compressor operation when
you don't have to.
Setback
Schedule
Automatically turn the thermostat set
point up a few degrees during unoccupied periods will reduce power consumption
10% to 20%
Equipment
Size
Bigger is not better. Over sized equipment will
short cycle and use more power. Select equipment according to the heat gain for
the building. Multi-stage or variable speed equipment are more efficient and closely
match the current load.
