An apparatus and a method for conditioning air has a quantity of liquid desiccant. A first portion of a first airflow is received in a first contact volume such that it contacts a first portion of the liquid desiccant. A second contact volume is in parallel with the first contact volume and receives a second portion of the first airflow. At least a portion of a second airflow is brought into contact with a second portion of the liquid desiccant in a third contact volume. A first heat exchanger is associated with the first portion of the liquid desiccant and configured to transfer heat between the first portion of the liquid desiccant and a first medium. A second heat exchanger is associated with the second portion of the liquid desiccant and configured to transfer heat between the second portion of the liquid desiccant and a second medium.
