[My chemical romance]

I am facing problems in determining the cause of low TR (Tons of Refrigeration) in a VAM (Vapor Absorption Machine) installed to utilise low grade heat from excess steam.

The data are as follows :

 

Model : Single Effect Vapor Absorption Chiller Steam Driven - Thermax India

 

Design TR : 500

It is supplying chilled water to 3 chillers .

 

 Chilled water    

         

TR1 144.79    

TR2 128.47    

TR3 145.24  

Totalised TR  418.5 2

        

Tin °C 16.1  

Tout °C 9.33  

Flow 1 m³/hr 62.75  

Flow 2 m³/hr 65.28  

Flow 3 m³/hr 62.75  

Total Flow m³/hr 190.78    

   

Vacuum mm Hg 7 

 

Steam                      

T °C 114        

Flow m³/hr 2553.79        

 

Cooling Water      

       

Tin °C 29.3  

Tout °C 35.5        

       

LiBr    

         

Generator Temp. °C 98  

LiBr Spray Temp. °C 65.44  

Conc. % 63.5

 

Can Someone having experience in dealing with VAM Systems suggest solutions !!
