Signal diodes also have many uses in processing signals in electronic equipment; they are used to obtain the audio and video signals from transmitted radio frequency signals (demodulation) and can also be used to shape and modify AC signal waveforms (clipping, limiting and DC restoration).
What is acceptable air conditioner outlet temperature? I have a 1996 Nissan Maxima. It was about 95 degrees today (measured with my own thermometer not what the weather report says), and my air conditioner outlet temperature was reading about 50 degrees. that would be temperature differential of about 45 degrees. I had the fan on second lowest out of 4 settings and on recirculation.
At standard design conditions, air coming out should be in the range of 55 to 60 degrees to cool the house down, regardless of the ambient house temperature. The unit should be able to cool even air at 85 degrees flowing into the unit down to 60 (at the vent) if it is functioning properly. Some factors that do influence the vent temp are where the unit is located, where the ducts are, how far the air has to travel, and the air speed.
