The present invention relates to a cooling chamber unit (30) for manufacturing a mask pack. More specifically, the cooling chamber unit (30)of the present invention comprises: a plurality of transfer rollers (31) which facilitate transfer of a laminating film for manufacturing a mask pack; a plurality of slit shaped nozzles (32) formed to be parallel with a processing direction of the laminating film in a longitudinal direction of the cooling chamber unit so as to inject cool air onto the laminating film; cooling pipes (33) which are connected to the nozzles (32) to supply the cool air; first and second coolers (34) which are connected to the cooling pipes (33), and include cooling coils to manufacture and supply the cool air; and exhaust ports (35) disclosed at a lower portion of the rollers to collect the cool air injected from the nozzles, and resupply the same to the coolers (34). The first and second coolers (34) alternatively operate and, for defrosting, refrigerants having high temperatures and high pressures are supplied to the cooling coils of the coolers of the first and second coolers (34) which do not operate. |
