Abstract (en)

[origin: WO0135039A1] An enthalpy pump (10) for altering the humidity level of an air stream (12, 14). The enthalpy pump comprises a container having a transfer portion (38) disposed in a first air stream (12), with a liquid desiccant contained in the transfer portion (38). The transer portion (38) is permeable to water vapor and impermeable to the liquid desiccant to thereby retain the liquid desiccant within the container while permitting exposure of the liquid desiccant to the first air stream. The transfer portion (38) is also adapted to move the liquid desiccant into and out of the first air stream whereby the latent and/or sensible energy of the first air stream can be altered.
