Title: Evaporation appts. for water produced by condensation in refrigerator - has trough with barriers forming large surface area
Inventor: FUCHS WERNER
IPC: F25D21/14
Filed: 1990-02-15
Abstract: A cold cabinet of the type used in supermarkets for displaying foodstuffs is provided with a refrigeration system which includes a condenser and evaporator. Any water produced by condensation on the external surface of the evaporator is drained into a specially shaped trough. This trough (1) is installed with the surface (4) horizontal.
