Abstract
An absorption cooling machine of the type which uses a refrigerant and an absorbent and which includes a high stage generator, absorber, condenser, heat exchangers, and an evaporator and means for connecting the components to one another to form a closed absorption cooling system. The solution side of the high stage generator is fluidically divided into two sections with a partition plate whereby gas exiting one section at relatively high temperature is further cooled in a second section called a flue gas recuperator (FGR) to improve overall burner efficiency.
Claims11
In an absorption cooling system of the type which uses a refrigerant and an absorbent solution and which includes a high stage generator, absorber, condenser, heat exchangers, and an evaporator and means for connecting said components to one another to form a closed absorption cooling system with said solution side of said high stage generator being fluidically divided with a partition plate into two sections of substantially identical construction whereby gas exiting one section at relatively high temperature is further cooled in the second section which functions as a flue gas recuperator (FGR) to improve overall burner efficiency.
In an absorption cooling system of the type which uses a refrigerant and a lithium bromide absorbent solution and which includes a high stage generator, absorber, condenser, high and low temperature heat exchangers, and an evaporator and means of connecting said components to one another to form a closed absorption cooling system with said solution side of said high stage generator being fluidically divided with at least one partition plate into at least two sections of substantially identical construction whereby gas exiting one section at relatively high temperature is further cooled in the second section which functions as a flue gas recuperator (FGR) to improve overall burner efficiency.
