Would it not run more efficiant if i removed the intake hose from pulling the warmer air from outside, and have it pull the colder inside air? Danby company says no. Why?

I might add, most portable a/c's do not have an outside air intake hose, just an outtake hose. Why doe's Danby use 1 in, and 1 out, and not other companies?

Most portable units have neither intake nor exhaust hoses. They draw air in and exhaust it directly through vents built into the exterior of the unit. Whichever way your unit works, it has been designed to work best in that way.
In the case of your question, it might have to work less hard if you ran cool air through the outside. But it would still be less efficient, since the source of that cool air is the AC itself.
What good it is to produce a lot of cold inside air if you're going to send a big chunk of it right back outside?

If you don't have an intake hose then you will be creating
a vacuum. You need the intake hose for circulation of
air; air must come in for air to come out.
Edit:
Epidavros included an important point I excluded in
that many refridgeration type units provide cooling
by pumping heat out of the air to be dispersed for
cooling and discarding the air which has received
that pumped out heat.

If you were trying to cool inside air and condensed the refrigerant with inside air you would reach an equalibrium temperature where no air conditioning would occur and would probably trip the A/C unit. multiple starts and stops as the temperature oes up and down like that is bad for the compressor in the machine and oyu will burn it out. Like most equipment it is happiest when it operates for longer periods of time

An AC is a heat pump. Hence it makes indoor air cooler by making outdoor air hotter. This means the vent pipes must take in outdoor air, make it hotter and put it back outdoors.
Anything else defeats the object and will result in no cooling.
