I believe that would be called return air.
It is a air flow diffuser at the end of the air flow where it enters the space to be conditioned.
drf ,diversified ref flow air conditioning
I call it the HVAC (Heating, Ventilation and Air Conditioning) box.
by letting the wind flow through the top and there you have the answer.
Fluid flow in an annular space occurs during a drilling operation of the gas and oil well. The correct prediction of the flow lies in the drilling mud in the annular space between the well.
blood flow is called circulation
it can be that the air filter is clogged and is blocking the air. it can easly be fix by taking the front part of the air conditioning off and checking the filter.
When we fly on earth or on other planets, we call this atmospheric flight. When we fly without the forces of a planet pulling on the spacecraft, which only occurs in space, hence we call it space flight. The reason these are differentiated is because of whether or not there are air molecules are present. With air molecules (atmospheric flight) Bernoulli's Principle applies, which explains air flow, and in the space flight it does not apply.
It was Frank Lloyd Wright's influence that created the open flow of space in today's homes.
Because the home is sealed in order to prevent air flow from outside to inside, air conditioning can cause dry skin. It also removes the humidity in the air.
You call a moveable part that controls the flow of gas in a pipe a valve. This regulates the flow of gas and can even turn the flow completely off depending on the circumstances.
Could be a dirty cabin filter.
