Title:
COLD STORAGE DEVICE USING BRINE CIRCULATION
Document Type and Number:
WIPO Patent Application WO/2013/172651
Kind Code:
A1
Abstract:
The present invention relates to a cold storage device using brine circulation, which significantly improves freezing efficiency by increasing a heating area of air and which has high defrosting efficiency. The cold storage device using brine circulation, according to the present invention, comprises: a cold storage tank in which a low-temperature latent heat PCM is stored; a cooler having a coolant circulation line, which comprises a input-side distribution pipe and an output-side header pipe that are arranged inside the cold storage tank, and a plurality of branching pipes which are connected between the input/side distribution pipe and the output-side header, and which is arranged so as to cool the low-temperature latent heat PCM inside the cold storage unit and to pass through the inside of the cold storage tank, wherein supply lines and collection lines of an AC cooler using AC power and a DC cooler using DC power are connected in parallel to the coolant circulation line; an outer case, which is installed so as to surround the cold storage tank, and is provided with a plurality of air aspiration ports on a lower portion thereof and an air discharge port on an upper portion thereof, wherein a first air aspiration port is positioned at the lower center of the outer case, and the second and third air aspiration ports are symmetrically positioned on the lower right and the lower left of the outer case; a brine circulation unit having an aspiration-side heat exchanger, which is arranged near the air aspiration ports on the outer case; a mixing unit for mixing the low-temperature latent heat PCM inside the cold storage tank; and an air circulation heat exchange passage which is arranged between the an outer surface of the cold storage tank and an inner surface of the outer case.
