    I suppose I should provide some context for the post above. As there are people who are trying to develop such refrigeration systems:

    Probably true.

    But if you think about it, the Thermador Car Cooler (as pictured above) does work off the refrigeration principle. I suppose the reason it is not considered a true ďA/C systemĒ is...

    Do you support banning this...

    Or you could completely replace the current A/C system with a R-718 system, as pictured below. The one problem with these older R-718 systems is that they continually need recharged, but I believe...

    That is how it works in most cases with squirrel cage type fans, centrifugal water pumps etc. -- as you close off the flow, the blower or pump will draw less current. What happens is that the air (or...

    If the job affords them then I think they are a great idea. I like blowing in the duct and running to the end and feeling my breath come out, that just doesn’t happen without turning vanes.

    I still canít come close to your number.

    Ok, I found a conversion calculator and the expansion rate of liquid R22 is 385 times to gas at 1 atmosphere. So 30 lbs divided by 385 equals .0779 lbs.

    Of course this isnít exact because new...

    That number seems high to me. I couldnít find the expansion rate of R-22, but propane is similar enough to R-22 that it can be used as a drop in replacement (usually not legally).
