Abstract

A subassembly for an adsorption chiller includes an adsorption component that includes a plurality of plates arranged in a stack. Refrigerant passages are defined between refrigerant sides of adjacent pairs of the plates in the stack. An adsorbent material is disposed within the refrigerant passages.

First claim

The invention claimed is:

1. A device, comprising:
a plate of an adsorption chiller subassembly, the plate comprising:
a refrigerant side surface configured to be in contact with a refrigerant and an opposing fluid side surface;
three sets of flow features formed in the refrigerant side surface of the plate, wherein:
the first set of the flow features is formed in a bottom region of the refrigerant side surface;
the second set of flow features is formed in a middle region of the refrigerant side surface;
the third set of flow features is formed in a top region of the refrigerant side surface; and
further comprising an adsorbent material disposed in and/or on the second set of flow features; and

a tray feature disposed between two of the sets of flow features.

2. A device comprising:
a plate of an adsorption chiller subassembly, the plate comprising:
a refrigerant side surface and an opposing fluid side surface;
evaporation, adsorption, and condensation flow fields formed in the fluid side surface of the plate; and
a first feature disposed on the fluid side surface of the plate and configured to fluidically decouple the evaporation flow field from the adsorption flow field; and
a second feature disposed-on the fluid side surface of the plate and configured to fluidically decouple the adsorption flow field from the condensation flow field.
