Abstract
A sorber comprised of at least three concentric coils of tubing contained in a shell with a flow path for liquid sorbent in one direction, a flow path for heat transfer fluid which is in counter-current heat exchange relationship with sorbent flow, a sorbate vapor port in communication with at least one of sorbent inlet or exit ports, wherein each coil is coiled in opposite direction to those coils adjoining it, whereby the opposed slant tube configuration is achieved, with structure for flow modification in the core space inside the innermost coil.
Claims20
A sorber comprised of:
- a) at least three concentric coils of tubing contained in a shell;
- b) a flow path for liquid sorbent in one direction through said sorber, into a sorber an entrance port and out a sorbent exit port;
- c) a flow path for heat transfer fluid through said sorber which is in counter-current heat exchange relationship with said sorbent flow path;
- d) a sorbate vapor port which is in communication with at least one of said sorbent ports;
- e) wherein each coil is coiled in opposite direction to those coils adjoining it, whereby the opposed slant tube configuration is obtained;
- f) wherein the tube slant angle of each coil is in the range of 85° to 50°;
- and
- g) wherein there is structure for flow modification in the core space inside the innermost coil.
An absorption cycle apparatus wherein the improvement comprises at least one opposed slant tube diabatic sorber comprised of at least three coils of tubing with coil-to-coil spacing less than 4 mm, said sorber utilized as any of the absorber, the desorber, the GAX, the refrigerant heat exchanger, the solution cooled rectifier, or the generator heat exchanger of said absorption cycle.
A cocurrent mass exchange sorber comprised of a shell and at least two concentric coils of tubing, characterized by:
- a. the coil axes are vertical;
- b. adjacent coils are coiled in opposite directions;
- c. the coil-to-coil and coil-to-shell spacing is less than about 1.5 mm, and less than one fourth of the tube diameter;
- d. each coil is comprised of at least two starts;
- and
- e. the core space inside the innermost coil is at least partially blocked.
