Energy efficient guidance for operating your AC unit
- 1. Energy efficient guidance for operating your air conditioning unit low carbon energy Temperature set points The ideal temperature set point for comfort conditions is 22 ºC to 23 ºC. Ensure all units in the same space are operating at the same set point. Don’t let separate heating and cooling systems operate at the same time. This can be avoided by setting a temperature ‘dead band’ awide gap between the temperatures at which heating and cooling cut in. The heating should switch offwhen a temperature of 19ºC has been reached and cooling should not come on until the temperature exceeds 24ºC. Ensure suitable time schedules are programmed The AC system should only operate within core working hours to avoid unnecessary energy use. Ensure suitable time schedules are programmed to switch offthe AC systemwhen it is not required. Do not open the windows when the AC is on This can result in excessive consumption of energy as the AC systemwill not be able to achieve its temperature set point and will run continuously. Maintain system components to ensure efficiency Energy consumption can increase by up to 60% if regular maintenance is not undertaken. Dirty orfaulty fans, air ducts and components directly affect system efficiency and will increase running costs and risk of breakdown. 0 10 15 Heating is on until temperature reaches 19⁰C Cooling is on when temperature exceeds 24⁰C Heating and Cooling both off between 19⁰C and 24⁰C - a ‘dead band’ of 5 degrees 5 20 25 30 35 40
