Abstract
An indirect-fired climate control apparatus for modifying certain aspects or properties of air flowing through a controlled environment, with the apparatus employing a rotary air-energy exchange device with means for bilaterally introducing and extracting energy from primary and secondary air flows. The apparatus includes a feature for recycling portions of the air flow on the primary side so as to more efficiently utilize the energy resource, and deliver this energy to the secondary side. The apparatus is suited for treating air flow with thermal energy for modifying its temperature, as well as energy for controlling the moisture content of the air flow on the secondary side.
