Abstract
A shell and tube type evaporator using a refrigerant and shell fluid and including a vertically positioned shell having an upper and lower end and substantially parallel tubes longitudinally disposed within the shell. The shell has inlet means near its lower end and outlet means near its upper end for passing the refrigerant through the tubes. The shell also has inlet and outlet means for passing the shell fluid through the shell. Preferably the refrigerant is ammonia and shell fluid is brine.
Claims30
A shell and tube type evaporator using a refrigerant and shell fluid comprising:
- a shell having an upper end and a lower end;
- substantially parallel tubes longitudinally disposed within said shell, each said tube having opposed upper and lower ends;
- first inlet means and first outlet means for passing the refrigerant through said tubes in an upwardly direction from said lower end of said shell to said upper end of said shell, said first inlet means being positioned near the lower end of said shell and being in communication with the lower ends of the tubes, said first outlet means being positioned near the upper end of said shell and being in communication with the upper ends of the tubes, said first inlet means including a pressure reduction device allowing the refrigerant to pass through said tubes at a pressure suitable for changing said refrigerant from a substantially liquid phase at said first inlet means to a substantially gaseous phase at said first outlet means;
- and
- second inlet means and second outlet means for passing the shell fluid through said shell, whereby heat is transferred between the refrigerant and the shell fluid.
A shell and tube type evaporator utilizing refrigerant and shell fluid comprising:
- a shell oriented in a vertical direction and having an upper end and a lower end;
- substantially parallel tubes longitudinally disposed within said shell, said tubes each having upper and lower ends and external surfaces;
- first inlet means and first outlet means for passing the refrigerant into and out of said tubes in an upward direction from said lower end of said shell to said upper end of said shell, said first inlet means being positioned near said lower end of said shell and being in communication with the lower ends of the tubes, first outlet means being positioned near the upper end of said shell and being in communication with the upper ends of the tubes, said first inlet means including a pressure reduction device allowing the refrigerant to pass through said tubes at a pressure suitable for changing said refrigerant from a substantially liquid phase at said first inlet means to a substantially gaseous phase at said first outlet means;
- second inlet means and second outlet means for passing the shell fluid into and out of said shell;
- baffles within said shell arranged within alternating horizontal planes, whereby said baffles redirect the flow of the shell fluid within said shell to increase contact between the shell fluid and the external surfaces of said tubes.
