When you heat air, the air pressure rises and the particles expand.
The furnance is not coming on.
It happens because the air is thin so heat can't travel , therefore they are cool.
This usually happens because the AC is set to heat and not cool. If it is set to cool then get it checked out by a qualified AC technician.
that all depends on the heat and cool air applied
The function of the evaporator is to cool the air by absorbing heat into the refrigeration system.
What do you think happens when some air heats up and other air is cool?
well a heat pump is used to heat or cool water and air conditioning is used to cool a room or home. So it would really depend on what you are trying to heat or cool
No, an air conditioner is designed to cool a room by removing heat, not to heat a room.
The air becomes cool and fresh.
He would heat it.
The rate of cooling is affected by the temperature difference between the warm substance (air in this case) and the substance that is gaining that heat. If they are close in temperature there will not be as fast am exchange of heat. If the warm air and the cool air in the question are being cooled by transferring their heat to a substance at a set temperature, then the warmer air will cool faster, because it has a bigger temperature differential from the substance than does the cooler air.
