Absorption chiller-heater

Abstract

There is provided an absorption chiller-heater comprising an exhaust gas flow path in which an exhaust gas flows; an exhaust gas fired regenerator provided on the exhaust gas flow path so as to be heated by the exhaust gas; a cooling medium solution passage supplying a first solution of a cooling medium which is collected by an absorber to the exhaust gas fired regenerator; and an exhaust gas heat collector provided on the cooling medium solution passage for carrying out heat exchange between the first solution and the exhaust gas.

What is claimed is:  
     
         1 . An absorption chiller-heater comprising: 
 an exhaust gas flow path in which an exhaust gas flows;    an exhaust gas fired regenerator provided on said exhaust gas flow path so as to be heated by said exhaust gas;    a cooling medium solution passage supplying a first solution of a cooling medium which is collected by an absorber to said exhaust gas fired regenerator; and    an exhaust gas heat collector provided on said cooling medium solution passage for carrying out heat exchange between said first solution and said exhaust gas.    
     
     
         2 . An absorption chiller-heater according to  claim 1 , further comprising: 
 a low temperature heat exchanger provided on an upstream side of said cooling medium solution passage with respect to a flow of said first solution therein for carrying out heat exchange between said first solution and a second of said cooling medium; and    a high temperature heat exchanger provided on a downstream side of said diluted solution passage with respect to said flow of said first solution therein for carrying out heat exchange between said first solution and a third solution of said cooling medium;    wherein said exhaust gas heat collector is provided on said cooling medium solution passage between the low temperature heat exchanger and the high temperature heat exchanger.    
     
     
         3 . The absorption chiller-heater according to  claim 1 , wherein said exhaust gas fired regenerator and said exhaust gas heat collector are integrated into a single unit.  
     
     
         4 . The absorption chiller-heater according to  claim 1 , wherein a first unit is integrally formed with a second regenerator, a condenser, the absorber and an evaporator, and 
 a second unit which is integrally formed with the exhaust gas fired regenerator and the exhaust gas heat collector is mounted on said first unit.
