Abstract

This invention relates to a refrigerator and to a refrigerating unit for a refrigerator that can be adapted by minor adjustment for mounting in refrigerating cabinets of different design. Essentially the refrigerating unit is a complete unit that has a chamber for the heat exchanger with two openings of similar perimeter design; covers are provided which can be fitted over either opening. One of the covers is solid and the other has an inlet and outlet opening designed to permit the ingress of air to the heat exchanger and the exit of air from the heat exchanger. Depending upon the type of refrigerated cabinet that the unit is to be installed in, the cover with the inlet and outlet openings is mounted on one or other of the openings in the chamber that houses the heat exchanger.

Claims

1. A refrigerating unit for a refrigerating cabinet comprising:

a base, a refrigerating heat exchanger, a chamber on said base for said refrigerating heat exchanger, said chamber having two openings with similar perimeter geometry, a first cover for either of said two openings, a second cover for either of said two openings, said first cover having an air inlet opening and an air outlet opening, circulating fan means in said chamber for moving air from said inlet opening of said first cover into heat exchange relation with said heat exchanger and out of said outlet opening of said first cover when said first cover is over either one of said two openings and said second cover is over the other one of said openings, means mounted on said base exterior of said heat exchanger for liquefying gaseous refrigerant from said heat exchanger and returning to said heat exchanger in liquefied form for evaporation by heat of air carried in heat exchange relation with said heat exchanger by said circulating fan means.

2. A refrigerating unit for a refrigerating cabinet as claimed in claim 1 in which one of said two openings in said chamber is a top opening and the other of said two openings in said chamber is a bottom opening.

3. A refrigerating unit for a refrigerating cabinet comprising:

a base, a refrigerated heat exchanger, a chamber on said base for said heat exchanger, said chamber having two openings with similar perimeter geometry, a first cover for either of said two openings, a second cover for either of said two openings, said first cover having an air inlet opening and an air outlet opening, said air inlet and said air outlet openings being adapted to permit the ingress and egress of air in heat exchange relation with said heat exchanger, means mounted on said base exterior of said chamber for liquefying gaseous refrigerant from said heat exchanger and returning it to said heat exchanger in liquefied form for evaporation by heat of air carried in heat exchange relation with said heat exchanger.

4. A refrigerating unit for a refrigerating cabinet as claimed in claim 3 in which one of said two openings in said chamber is a top opening and the other of said two openings in said chamber is a bottom opening.
