With an ammonia absorption system, what is the minimum Evaporative Temperature that could be attained and as compared with refrigeration reciprocating system what would be the operating expense. I am talking about a refrigeration capacity of 171 kw. As I know that for the operation of the absorption system, heat is required. Does it work economical for an unit where there is no heat generation is available and to operate this, an extra boiler has to be installed. Kindly explain to me the working and some technical details of this system.

With best wishes,
