Abstract
A membrane-based assembly and process for cooling and/or de-vaporizing a gas. The assembly and process can provide sensible cooling and/or dehumidification of air, and can be contained within a single, integrated apparatus.
Claims13
A vapor-removing and cooling system comprising:
- a) a plurality of vapor-removing and cooling assemblies disposed in a stacked arrangement and wherein:
- said vapor-removing assemblies comprise a flow volume region having a first surface and a second surface, the flow volume region adapted to receive a first working fluid flow under partial vacuum;
- a first selectively water vapor permeable membrane having a first side in mass transfer relationship with the first surface of the flow volume region and having a second side configured for contact with a water vapor-containing gas to permit transfer of at least a portion of the water vapor from the water vapor-containing gas through the first selectively water vapor permeable membrane and into the first working fluid flow;
- and
- said cooling assemblies having a mass transfer relationship between a second working fluid flow and an evaporable liquid to provide formation of an evaporant from the evaporable liquid and permit transfer of at least a portion of the evaporant from the liquid into the second working fluid flow, wherein the mass transfer relationship between the second working fluid flow and the evaporable liquid comprises a barrier for maintaining the second working fluid flow above a first surface of the evaporable liquid to permit formation of an evaporant from the evaporable liquid and transfer of at least a portion of the evaporant into the second working fluid flow;
- b) interiorly-defined channels providing separate flow paths for the vapor-containing gas, the evaporable liquid, and the first and second working fluids, the interiorly-defined channels in fluid communication with the plurality of vapor-removing and cooling assemblies;
- c) one or more inlets in fluid communication with the interiorly-defined channels;
- and
- d) one or more outlets in fluid communication with the interiorly-defined channels.
