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.
When we do home inspections, we expect the temperature at any vent in the house, with the air conditioner in cooling mode, to register 20 degrees below the ambient temperature in the room. Typical supply air temperature directly at the A/C unit air outlet is about 55 deg F dry bulb temperature.
