Abstract
A climate controlled seat, bed or other assembly configured to receive a person includes a blower and two or more thermoelectric devices or other conditioning fluid modules. According to one embodiment of an operational scheme, a control system for the seat or bed is configured to continuously discharge air from the blower through the thermoelectric devices. In one arrangement, the thermoelectric devices are sequenced between an activated and a deactivated position. Consequently, the desired cooling and/or cooling effect can be maintained while reducing energy consumption of the climate control system.
