If you wish to save fuel and you’re going to leave your cool house for a half hour or so on a very hot day, should you turn your air-conditioning thermostat up a bit, turn it off altogether, or let it remain at the room temperature you desire?
Step 1 of 3
The rate of heat transfer is proportional to temperature difference.increasing the temperature will increase the amount of heat transferred,and turning up a bit your thermostat will consume some energy.i live in a fairly well-insulated house,and furnace comes on bit less than every half an hour on a hot day. If you going to leave for short amount of time,you can leave it on.it takes less energy to kept a room at a certain temperature than to let it warm considerably.if you talking about leaving it for several hour better to turn-off altogether.
