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.
The best air conditioning temperature for sleeping is whatever you can get by on with just a sheet over you. If you have the air conditioner set so low that you need pajamas and a comforter, you have it set too low. Try working your way up from that 82F to 84F, 86F, or even higher.
