Dear MEMBERS: See If you can help me out answering following questions I would be very grateful to you : 1. I read somewhere , I do no recall where , that for every degree higher, one sets the temperature of the room the air conditioner has to cool , the electrical energy savings would be 3% , is it true ? and where in the internet can I read about it ? 2. when one designs the size of a coolong air conditioner for a specific space , how much of the time should the compressor as normal be running if the thermostat is set to 78 F ?Remember that if the compressor runs , lets say 50% of the time , one can save a lot of electricity because 80% of the total energy consumption of a cooling air conditioner is done by the compressor . 3. If in the example above one decides to lower the thermostat to 70 F , percentage wise how much longer would run the compressor if the other conditions are exactly alike like people , number of times door opens etc ? 3. Is it true or not that instead of leaving the evaporator fan in the auto position , it should be left in the on position , because that way the compressor would run less time and not like it is recommended to leave in the auto position to save energy ? ( compressor draws 8 - 9 times more power than evaporator fan ) thank you for your promtly reply
