A thermoelectric-based air conditioning system is provided. The system includes at least a first supply air channel and a separate second supply air channel disposed in a housing. The system also includes a first thermoelectric cooler (TEC) forming at least a portion of the first supply air channel and configured to independently condition air within the first supply air channel. The system further includes a second TEC forming at least a portion of the second supply air channel and configured to independently condition air within the second supply air channel. The system includes a printed circuit board (PCB) configured to provide an electrical connection between the first TEC and the second TEC. The system further includes a mold substrate configured to over-mold the first TEC and the second TEC.

There is a significant amount of literature that discusses thermoelectric power generator (TEG) design, but much of it overly simplifies the design space and therefore the results have limited use in designing real-life systems. This paper develops a more comprehensive model of the thermal and electrical interactions of a TEG in a system with known hot-side and cold-side thermal resistances and corresponding constant system temperature differential. Two design scenarios are investigated for common TEG system applications. In one method, the power from a TEG is maximized for a given electrical load, simulating a case where the TEG is electrically in series with a known load such as a fan. In the second design scenario, the power from a TEG is maximized for a given electrical load resistance ratio, n (the ratio between the external load resistance and the internal TEG resistance), simulating an application where the TEG is electrically in series with a load-matching converter. An interesting conclusion from this work is that, in the first design scenario, the electrical load resistance ratio, n, that maximizes TEG power occurs at √1+ZT (where ZT is the thermoelectric figure of merit) instead of 1 as reported previously in literature. Equally interesting is that, if you define an analogous thermal resistance ratio, m′ (representing the ratio between the TEG thermal resistance at open-circuit conditions and the system thermal resistance), the maximum power in both design scenarios occurs at √1+ZT instead of the commonly cited value of 1. Furthermore, results are presented for real-life designs that incorporate electrical and thermal losses common to realistic TEG systems such as electrical contact resistance and thermal bypass around the TEG due to sealing. © 2012 TMS.

A system and method is provided for controlling condensation generation in an air conditioning system for use in a bed (mattress). During active operation of the air conditioning system to generate conditioned air, the relative humidity of ambient air is measured and operation of one or more thermoelectric devices (TEDs) within the air conditioning system in response to the measured relative humidity is adjusted to control condensate buildup. In addition, during a subsequent drying operation, the relative humidity of the ambient air is measured and the drying operation is adjusted or otherwise controlled based on the measurement.

A distribution system is adapted for use with a mattress (50) and a personal comfort system (100) with an air conditioning system operable for outputting a conditioned air flow. The distribution system includes at least top and bottom layers of fabric material and a spacer structure (230) disposed between the bottom and top layers. The spacer structure defines an internal volume within the distribution layer (110) and is configured to enable the received conditioned air flow to flow therethrough. This flow of conditioned air has a cooling or heating effect on a body on the mattress. A system for controlling ventilation in a mattress includes an user-controlled air conditioning control system (105) for generating and supplying a conditioned air flow to a distribution layer/system located on or near the mattress. The distribution layer/system includes a spacer structure (230) surrounded by fabric material and configured to receive the conditioned air flow and provide a cooling or heating effect to a body adjacent the mattress.
