Abstract:
An enthalpy pump for altering the humidity level of an air stream, the pump comprising:a container having a transfer portion adapted to hold a liquid desiccant, wherein the container comprises a conduit forming a circulation loop that will extend through a first air stream and through a second air stream, the transfer portion being permeable to water vapor and impermeable to liquid desiccant so as to retain the liquid desiccant within the container while permitting exposure of the liquid desiccant to the air streams, wherein the transfer portion includes a first portion to be located in the first air stream and a second portion to be located in the second air stream, the transfer portion further being adapted to move liquid desiccant into and out of at least one of the air streams whereby humidity in at least one of the air streams can be altered.
