I am testing this thing at the moment... ohh I am afraid I won't be able to measure temperature without a fan as:
1. I don't feel like removing it
2. I don't think I have a thermometer that goes that high
it has been already running for over an hour... I'll update it once it's done
ambient temperature was 30 deg C (I keep it in a greenhouse Duhh
The compressor was on for ~1.5 hour... the temperature of the casing was 52 deg Celsius
not bad but it was much warmer than usually... something tells me it isn't the best idea to keep it in a greenhouse
ohh BTW I have several kilos of copper strips... in case you don't know what I am talking about -> http://www.indiamart.com/pushpatrading/ ... erial.html
any idea if it's possible to solder it to the casing ?
ohh and finally...
boyntonstu suggested pressurising the input... it works due to the fact that air experiences compression heating in the first stage and dissipates heat through the first stage compressor and the air reservoir... thus the second stage has less heat to deal with
you can read about it here -> http://www.domnickhunter.com/technicalcentre/3.3.1
If the compressor was designed to be fan cooled in an enclosure, it will come with a fan and/or an oil cooler coil
heh what you failed to notice is the fact that fridge compressors are designed to pump refrigerant in a closed circuit, which is not the same as compressing ambient air...
How come you acknowledge that there is a thing called compression heating when you talk about pressurising air input but you claim that pumping refrigerant is the same thing as compressing ambient air?
