What happens when you blow hot or cold air?
What happens when you blow hot or cold air?
We have observed that if we blow fast from a small opening the air comes out cold. Whereas, if we blow slowly from a large opening the air is hot. Further, if we place our hand on our mouth, it feels warm, i.e. we feel hot air. Then again if we move it away, the air feels cold. Let’s understand what is happening here.
Why is my AC blowing hot air all the time?
High evaporator Delta T means that the incoming temperature and outgoing temperature is excessively large. It’s usually caused by low air flow across the coil, which includes problems like: A dirty air filter Fan set to an incorrect speed A dirty evaporator coil Ductwork is too small Learn more about why your AC is blowing hot air. Solution:
What should temperature be coming out of vent?
In a normally operating air conditioner, the temperature of air coming out of the supply vents should be about 20˚F lower than ambient temperature inside the room. This means that if your room is currently at 90˚F, then the cool air coming out of the supply ducts should be at around 70˚F.
Why do you blow cold air on your hands?
Blowing Cold and Hot Air. You might remember countless experiences of people blowing on their hands on a chilly winter morning. This activity helps to keep their hands warm. When given something hot to drink, you blow over it to make it mildly hot.

How cold should the air coming from my air conditioner be?
Now, from the example above, with 75 degree air being pulled in at the air filter, what temperature should we expect to be blowing out? Well, the general consensus is somewhere between 14 to 20 degrees colder than the intake temperature. From my example, 55 to 61 degrees would be an acceptable range.
Is the temperature of the AC always the same?
Well, there’s not a universal, fixed temperature your AC should always be blowing. The temperature your AC puts out is relative to the temperature you set on your thermostat. So even though there’s no single ideal temperature, you dowant a 16°–22° F difference from the supply air and return air.
