An absorption refrigerator which is capable of effectively using energy without a necessity of enlarging the size thereof, the absorption refrigerator having a structure that a cylindrical wall is provided for an inner wall portion raised because of a stepped portion of the bottom surface of a double-tube unit so that a refrigerant retainer for accumulating water allowed to downwards flow along the outer surface of a cold-water tube is formed. A refrigerant-circulating passage is connected to the bottom surface of the refrigerant retainer. Another end of the refrigerant-circulating passage is connected to a refrigerant supply passage. When a pump is operated, water in the refrigerant retainer is supplied to a water-receiving pan so as to again be sprayed to the outer surface of the cold-water tube.

Absorption refrigerator

The absorption chamber of an absorption-type air-conditioning apparatus is formed as a vertically oriented cylinder having an inner surface on which absorption liquid is dispensed for absorbing water vapor or coolant vapor. A guide structure is installed at the inner surface of the cylinder to lead the absorption liquid to the inner surface of the cylinder and to spread the absorption liquid over substantially all of the inner surface of the cylinder. The guide structure may be in the form of a mesh lath rolled into a cylindrical shape and installed against the inner surface of the cylinder or a helical coil installed against the inner surface of the cylinder and having a plurality of grooves formed on an outer surface of the coil to allow a portion of the absorption liquid flowing on an upward-facing surface of the coil to flow vertically downward to portions of the inner surface of the cylinder.

Absorption liquid spreading structure for interior of absorption chamber

An absorption-type air-conditioning apparatus uses an absorption liquid that is a solution of a liquid coolant and an absorption medium. First and second regenerators are provided for heating the absorption liquid to release coolant vapor and concentrate the absorption liquid. Each of the regenerators includes a respective fin-tube-type heat exchanger in which the absorption liquid flows as it is being heated.
