Adsorption system
An adsorption system can be used as part of a climate control system in a vehicle or in any other space requiring heating or cooling. An adsorbent bed can include a plurality of plates, a layer including an adsorbent material adjacent to a portion of at least one plate; and a plurality of passages between the plates.
1. An adsorbent bed comprising:
a housing including an inlet manifold, an exit manifold and a plurality of pairs of plates;
wherein each pair of plates of said plurality of pairs of plates define a flow channel within each respective pair of plates;
said flow channels are in fluid communication with the inlet manifold and the exit manifold,
wherein the pairs of plates are arranged in a stack;
wherein each pair of plates of said plurality of pairs of plates includes an upper layer including adsorbent material and a lower layer including adsorbent material and the vapor channel of each respective pair of plates being between the upper layer and the lower layer;
at least one airflow passage being provided between two immediately adjacent pairs of plates of said plurality of pairs of plates, said at least one airflow passage being configured to allow air to flow through the at least one airflow passage;
wherein each pair of plates of said plurality of pairs of plates are sealed, thereby preventing the air to flow into the respective flow channel of each pair of plates of said plurality of pairs of plates;
wherein the plurality of pairs of plates include a top most pair of plates, a bottom most pair of plates and at least one intermediate pair of plates;
wherein the vapor channel of the at least one intermediate pair of plates is fluidly connected to the vapor channels of the pairs of plates immediately above and below said at least one intermediate pair of plates via at least one raised portion.
2. The adsorbent bed of claim 1 , wherein the adsorbent material comprises a zeolite, biporous zeolite, or metal oxide framework.
3. The adsorbent bed of claim 2 , wherein the adsorbent material comprises 13X, MCM-41, MFI, VPI-5, MOF-199, Mg-MOF-74, ZIF, MOF-5, MOF-177, or MOF-210.
4. The adsorbent bed of claim 1 , wherein the adsorbent material comprises graphite flakes or carbon nanotubes.
5. The adsorbent bed of claim 1 , wherein the upper layer including adsorbent material has a thickness in the range of about 0.1-20 mm.
6. The adsorbent bed of claim 5 , wherein the upper layer including adsorbent material has a thickness in the range of about 1-5 mm.
7. The adsorbent bed of claim 1 , wherein a first plate of each of the plurality of pairs of plates comprises a raised perimeter extending in a first direction perpendicular to a top surface of the first plate.
8. The adsorbent bed of claim 7 , wherein the first plate of each of said at least one intermediate pair of plates comprises a plurality of holes arranged along the top surface and a raised portion of said at least one raised portion surrounding each hole and extending from the first plate in a second direction opposite to the first direction.
9. The adsorbent bed of claim 8 , wherein the raised perimeter and the top surface of the first plate defines a volume for receiving the upper layer including adsorbent material.
10. The adsorbent bed of claim 9 , wherein a second plate of each of said plurality of pairs of plates comprises a plurality of holes arranged along a top surface of the second plate and a raised portion of said at least one raised portion surrounding each hole in the second plate, wherein the raised portions of the second plates extend from the second plate in the first direction, wherein raised portions of the first plate are joined to respective raised portions of a second plate of immediately adjacent pairs of plates.
11. The adsorbent bed of claim 1 , wherein fins are located within each pair of the plurality of plates.
12. The adsorbent bed of claim 11 , wherein a housing provides thermal communication between the internal fins and a plurality of external fins.
