Air-cooled absorption-type air conditioning apparatus with vertical heat-transfer fins

An air-cooled absorption-type air conditioning apparatus for performing both cooling and heating operations, the apparatus comprising:

• circulation pipes through which a thermal medium flows, said thermal medium for controlling room air temperature;
• outer pipes provided concentrically and outside of sections of said circulation pipes to form chambers between said circulation pipes and said outer pipes;
• a fan for blowing air over said outer pipes;
• first spray mechanisms for dispensing a liquid coolant over outer surfaces of said circulation pipes in the chambers formed between said circulation pipes and said outer pipes;
• and
• second spray mechanisms for dispensing an absorption liquid onto inner surfaces of said outer pipes and said chambers, said absorption liquid for absorbing said liquid coolant;
• said first spray mechanisms being positioned in said chambers above said circulation pipes and extending parallel to a longitudinal axis of the circulation pipes;
• and
• said second spray mechanisms including a pair of spray pipes in each of said chambers extending parallel to said longitudinal axis of the circulation pipes, a first pipe of each pair of spray pipes disposed above a central axis of the respective circulation pipe and to one side of the respective circulation pipe, and the other pipe of said each pair of spray pipes disposed above said central axis of the respective circulation pipe and to an opposite side of the respective circulation pipe relative to said first pipe.
