Filed: 1956-12-18
Abstract: <PICT:0821351/III/1> <PICT:0821351/III/2> A defrosting system for a cooling coil using an inhibited ethylene glycol as defrosting liquid comprises a plurality of nozzles oriented to spray the coil with glycol, a sump below the coil to collect the glycol and frost, and a glycol concentration comprising a reboiler and a fractionating column.  The reboiler contains a steam - operated heat - exchanger, the condensate from which is introduced to the top of the fractionating column as an auxiliary liquid causing the glycol in the vapours rising therein to condense and reflux.  Means are provided for circulating liquid between the reboiler and the sump below the cooling coil.  Glycol is sprayed from nozzles 4 over cooling coil 3 and collects in sump 5 from which it is pumped by pump 7 to line 10 whence a part is recycled to the nozzles 4 and the remainder is diverted to tank 13.  Diluted glycol from tank 13 passes through line 18 and heat-exchanger 19 to the concentration 21 comprising a reboiler surmounted by a distilling column.  The reboiler is heated by a steam coil 35 from which the condensate is transferred via line 73 to tank 78 whence it is introduced to the top of the distillation column by distributer 56.  The glycol vapour undergoes phase interchange with the steam condensate in the column, the condensed glycol dripping back to the reboiler wherein the level is determined by an adjustable swivelled loop outlet pipe 83.  The concentrated glycol is pumped by pump 87 through heat exchanger 19 to tank 13 whence it is supplied by pump 15 to maintain the liquid in the sump 5 at a level determined by float valve 17.  The distillation column 40 (see Fig. 2) contains packing, e.g. Raschig rings or ceramic saddles supported by a perforated cone 42.
