Abstract
A refrigerator for maintaining high humidity therein where the evaporator surfaces are oversized and maintained at a frost-free temperature, continuous forced air is passed over the evaporator and over a drip water dish within the refrigerator compartment, and the compartment is vented to the outside of the refrigerator.
Claims13
A high humidity refrigerator for preventing the withdrawal of moisture from food products therein, said refrigerator including
- (a) a cold insulated compartment
- (b) a compressor, condenser and evaporator connected by refrigerant lines
- (c) said evaporator being positioned within, and in the upper portion of, said cold insulated compartment, and having a surface temperature above 0.degree. C.
- (d) a continuously operating fan located within said cold insulated compartment above said evaporator for directing air vertically downwardly past the evaporator to prevent icing of the evaporator surface, resulting in the formation of condensation thereon, and
- (e) a drip dish in the lower portion of the compartment beneath the evaporator for receiving water produced by the condensation dropping from the evaporator
- (f) said drip dish lying in the direct path of the air flow from the fan, whereby the air impinges upon the water contained in the drip dish to constantly absorb moisture therefrom and return it into the air surrounding the goods being refrigerated.
