Has anyone ever seen a compressed air chill assist?

{"text":"What I mean is this:\n\nYou pull into a shipper, and your load data says you have a 28 degree no-freeze meat load.\n\nYou ACTUALLY have a -10 frozen load and the shipper wants you at temp before you get in a door.\n\n28 to -10 will take a while, even on a good trailer.\n\nHere is where my idea comes in.\n\nPut a large air tank below the reefer unit. Insulate it, and put heat exchangers for the main chiller around it.\n\nThe air for this unit is drawn from the box, and returns from the box.\n\nHere's the cycle/function:\n\nThe tank is filled all the time, until it reaches pressure.\n\nThis heats the air in the tank.\n\nThe heated air in tank is chilled by the ice forming around the heat exchanger.\n\nWhen stable, the air in tank will be both compressed and cold.\n\nIf you need to rapidly drop temp in trailer, open the tank and release the cold, compressed air into the trailer while pulling hotter air out.\n\nThe cold, compressed air will depressurize and chill the air even more, leading to a rapid temperature drop in the box.\n\nThe compressor starts re-compressing air after the tank empties.\n","pics":"[]","canComment":true}
