Claim 3
Dependent Claim
19 words
A system according to claim 1 wherein said non-electrical means is a propulsion means disposed aboard a marine vessel.
Claim 4
Dependent Claim
36 words
A system according to claim 2 wherein said container and refrigerant passIng means comprises tubing in a generally serpentine form disposed within said container and inlet and outlet means connected to said tubing through said container.
Claim 5
Dependent Claim
68 words
A system according to claim 3 wherein said insulated enclosure is divided into a refrigerator space and a freezer space, and wherein at least two coldbanks are disposed in the freezer space which coldbanks are connected in series to one another and further comprising means for transmitting cold air from the freezer space to the refrigerator space and warm air from the refrigerator space to the freezer space.
Claim 6
Dependent Claim
40 words
A system according to claim 3 which comprises means for drawing sea water from the sea, passing it through the heat exchanger to absorb heat from the refrigerant flowing therethrough and passing said heated sea water back into the sea.
Claim 7
Dependent Claim
