Air-conditioning refrigerator

Claim 2

An air-conditioning refrigerator which, in combination with a conventional refrigerator having separate freezer and refrigeration compartments, with separate freezer compartment and refrigeration compartment doors, comprises the following: an air-conditioning cooling coil unit; a blower and motor unit; an enclosing housing attached to the inside of the freezer compartment door within which the air conditioning cooling coil unit and the blower and motor unit are located; the freezer compartment door having a first opening for entry of air and a second opening for the exit of cooler air; the blower and motor unit being positioned as to draw air in through the first opening in the freezer compartment door, past the air-conditioning cooling coil unit, and out through the second opening in the freezer compartment door; an air-conditioning motor-compressor unit; freon lines interconnecting said motor-compressor unit and said cooling coil unit; freon condensing means located between said motorcompressor unit and said cooling coil unit.

Claim 3

The air-conditioning refrigerator recited in claim 1, wherein said freon condensing means includes a water-cooled condensor.

Claim 4

The air-conditioning refrigerator recited in claim 2, wherein said water-cooled condensor comprises concentric tubing, wherein inner tubing transports freon in a heated state, and outer tubing, of greater diameter, transports circulating cooling water in contact with the inner tubing, wherein the circulating cooling water removes heat from the inner tubing and its transported freon.

Claim 5

The air-conditioning refrigerator recited in claim 3, wherein the outer tube of said water-cooled condensor comprises approximately ten feet of 3/4-inch diameter water-carrying tubing concentrically oriented about the inner freon carrying tubing of 3/8-inch diameter.

Claim 6

The air-conditioning refrigerator recited in claim 3, wherein the flow of water through said outer tubing is regulated by an automatic water valve controlled by the head pressure of the compressor.

Claim 7

The air-conditioning refrigerator recited in claim 3, wherein said water-cooled condensor is mounted on the back of the refrigerator.

Claim 8

The air-conditioning refrigerator recited in claim 1, wherein a three-way electrical switch is located on the freezer compartment door, with a first position to operate both the motor-compressor unit and the blower and motor unit, a second position to operate only the blower and motor unit, and a third position as a power off position.

Claim 9

The air-conditioning refrigerator recited in claim 1, where the freon lines enter the freezer compartment door through an aperature formed at the rotational axis of a hinge of the freezer compartment door.

Claim 10

The air-conditioning refrigerator recited in claim 1, which additionally includes condensate discharge tubing which proceeds through aperatures formed at rotational axes of hinges of the refrigerator compartment door so as to carry condensate water away from said housing.

Claim 11

An air-conditioning refrigerator which, in combination with a conventional refrigerator having separate freezer and refrigeration compartments, with separate freezer compartment and refrigeration compartment doors, comprises the following: an air-conditioning cooling coil unit; a blower and motor unit; an enclosing housing attached to the inside of the freezer compartment door within which the air conditioning cooling coil unit and the blower and motor unit are located; the freezer compartment door having a first opening for entry of air and a second opening for the exit of cooler air; the blower and motor unit being positioned as to draw air in through the first opening in the freezer compartment door, past the air-conditioning cooling coil unit, and out through the second opening in the freezer compartment door; an air-conditioning motor-compressor unit; freon lines interconnecting said motor-compressor unit and said cooling coil unit, wherein the freon lines enter the freezer compartment door through an aperature formed at the rotational axis of a hinge of the freezer compartment door; freon condensing means located between said motor-compressor unit and said cooling coil unit which includes a water-cooled condensor comprising concentric tubing, wherein inner tubing transports freon in a heated state, and outer tubing, of greater diameter, transports circulating cooling water in contact with the inner tubing, wherein the circulating cooling water removes heat from the inner tubing and its transported freon; and condensate discharge tubing which proceeds through aperatures formed at rotational axes of hinges of the refrigerator compartment door so as to carry condensate water away from said housing.

Claim 12

An air-conditioning refrigerator which, in combination with a conventional refrigerator having separate freezer and refrigeration compartments, with separate freezer compartment and refrigeration compartment doors, comprises the following: an air-conditioning cooling coil unit; a blower and motor unit; an enclosing housing attached to the inside of the freezer compartment door within which the air conditioning cooling coil unit and the blower and motor unit are located; the freezer compartment door having a first opening for entry of air and a second opening for the exit of cooler air; the blower and motor unit being positioned as to draw air in through the first opening in the freezer compartment door, past the air-conditioning cooling coil unit, and out through the second opening in the freezer compartment door; an air-conditioning motor-compressor unit; freon lines interconnecting said motor-compressor unit and said cooling coil unit, wherein the freon lines enter the freezer compartment door through an aperature formed at the rotational axis of a hinge of the freezer compartment door; freon condensing means located between said motor-compressor unit and said cooling coil unit which includes a water-cooled condensor comprising concentric tubing, wherein inner tubing transports freon in a heated state, and outer tubing, of greater diameter, transports circulating cooling water in contact with the inner tubing, wherein the circulating cooling water removes heat from the inner tubing and its transported freon; and condensate discharge tubing which proceeds through aperatures formed at rotational axes of hinges of the refrigerator compartment door so as to carry condensate water away from said housing.
