Disclosed is a system for conditioning air, the system comprising: a heat exchanger comprising a plurality of heat transfer tubes extending between an accumulation header and an outlet header, an internal volume, and an external surface, wherein an air mover is disposed in fluid communication with an air mover in fluid communication with an air inlet and an air outlet, wherein the air mover is configured to urge a flow of air to be conditioned across the external surface of the heat exchanger, a reactor comprising an adsorbent material, a reactor inlet in fluid communication with the outlet header, and a reactor outlet, a vacuum pump comprising a vacuum pump inlet in fluid communication with the reactor outlet and a vacuum pump outlet in fluid communication with a system exhaust.

A molecular sieve chamber comprises a plurality of containers generally parallel to another and arranged in a matrix having adjacent rows that may be offset from one another. The plurality of containers may be spaced from one another forming a plurality of tortuous air passages from a first side of the molecular sieve chamber to a second side of the molecular sieve chamber opposite the first side. Each of the plurality of containers may include a venting passage having a plurality of apertures, and at least one molecular sieve positioned between the venting passage and a solid sidewall. A fan may be configured to blow air between the plurality of containers in a direction generally perpendicular to a longitudinal axis of the plurality of containers. The venting passages of each of the plurality of containers may be fluidly coupled to one another.

A system includes an evacuated tube solar adsorption heat pump (ETSAHP) module. The ETSAHP module includes a transparent or semi-transparent tube configured to receive heat input from solar energy, the tube having a hollow interior, a top section, and a bottom section opposite the top section, an adsorbent bed comprising a plurality of adsorbent beads and positioned at the top section of the tube and configured to absorb solar energy, an adsorbent bed cage configured to contain the adsorbent bed at the top section of the tube, a threshold configured to stabilize the adsorbent container within the tube, and a condenser/evaporator positioned at the bottom section of the tube and spaced apart from the adsorbent bed.

Disclosed is an adsorption-based heat pump useful for refrigeration and cooling/heating for applications such as HVACs and chillers. Adsorption is a surface phenomenon where a solid substance (adsorbent) attracts molecules of a gas or solution (refrigerant or adsorbate) on its surface. The latent heat of the adsorbate provides the heating/cooling effect. The novel adsorption heat pump enhances heat and/or mass transfer to and from the adsorbate. One embodiment comprises at least one evaporator, at least one desorber (adsorbent heating apparatus), at least one adsorbent cooling apparatus and at least one condenser. The embodiment employs different techniques to enhance heat and/or mass transfer.

A refrigerator includes a main body that has a storage chamber and a drying chamber; a thermoelectric module that includes a heat absorber and a heat dissipater; a cooling fan that circulates air in the storage chamber to the heat absorber and the storage chamber; a heat-dissipating fan that blows air to the heat dissipater; an air guide that has a passage for guiding air heated by the heat dissipater to the drying chamber; a heater that is disposed in the passage; and a damper that controls a flow of air in the passage between the heat-dissipating fan and the heater. Heat of the heat dissipater transfers to the drying chamber through the passage of the air guide and the damper, thereby being able to dry an object to be dried.

The present invention provides a hybrid adsorption heat exchanging device comprising: at least one tubular or micro channel structure for carrying a heat transfer fluid; the external surface of said structure being provided with extensions in at least two locations; said extensions forming a bed therebetween for providing one or more adsorbent materials; a coating of adsorbent material being provided on at least a part of said extensions.

Adsorption heat exchanger devices (11, 25) are provided for use in solid sorption refrigeration systems (1) together with methods for making such devices and adsorbent structures therefor. The methods include applying a curable binder, in solution in a solvent, to granular adsorbent material, and then evaporating the solvent and curing the binder. The curable binder solution is sufficiently dilute that, during evaporation of the solvent, the binder becomes concentrated around contact points between granules (18) of the adsorbent material whereby localized bonds (19) are formed around the contact points on curing of the binder.
