Variable temperature seat climate control system
17 Nov 1994-
TL;DR: In this paper, a temperature climate control system comprises a variable temperature seat (10), at least one heat pump (26 and 28), one heat sensor (54 and 56), and a controller (64), each heat pump comprises a number of Peltier thermoelectric modules for temperature conditioning the air in a main heat exchanger (34 and 36) and a main exchanger fan (42 and 44).
Abstract: A temperature climate control system comprises a variable temperature seat (10), at least one heat pump (26 and 28), at least one heat pump temperature sensor (54 and 56), and a controller (64). Each heat pump comprises a number of Peltier thermoelectric modules for temperature conditioning the air in a main heat exchanger (34 and 36) and a main exchanger fan (42 and 44) for passing the conditioned air from the main exchanger to the variable temperature seat. The Peltier modules and each main fan may be manually adjusted via a temperature switch (60) and a fan switch (58), respectively. Additionally, the temperature climate control system may comprise a number of additional temperature sensors (102 and 104) to monitor the temperature of the ambient air surrounding the occupant as well as the temperature of the conditioned air directed to the occupant.

TL;DR: In this article, a system for thermally conditioning and pumping a fluid is described, which consists of a thermoelectric heat exchanger having a temperature-sensitive device configured to pump heat.
Abstract: Disclosed is a system for thermally conditioning and pumping a fluid. The system includes a thermoelectric heat exchanger having a thermoelectric device configured to pump heat. Heat exchangers are provided for transferring heat to and from the thermoelectric device and for generating a fluid flow across the thermoelectric device. The conditioned fluid may be placed in thermal communication with a variety of objects, such as a vehicle seat, or anywhere localized heating and cooling are desired. Thermal isolation may also be provided in the direction of flow to enhance efficiency.

TL;DR: A vehicle seat with a backrest cover is at least partially air permeable, and covers at least one passage of the air-handling device as discussed by the authors, where the air exchanged between the environment and the air handling device passes for the most part through the air permeable regions of the backrest covers.
Abstract: A vehicle seat with a backrest ( 16 ) that has a backrest cushion ( 18 ) and a rear backrest cover ( 20 ), and an air-handling device that is associated with the backrest ( 16 ) and is connected to an air distribution device ( 30, 32 ) in the seat. The rear backrest cover ( 20 ) is at least partially air permeable, and covers at least one passage ( 27 ) of the air-handling device ( 23 ). The air exchanged between the environment and the air-handling device ( 23 ) passes for the most part through the air-permeable regions of the backrest cover ( 20 ).

TL;DR: In this paper, the authors describe a seat construction with joined seat and backrest parts, and a plenum into which is received temperature conditioned air, where coil springs define the plenum and a covering is secured over the springs consisting of, from the inside out, a metal mesh layer, an elastomer sheet with a number of openings, and an air permeable fabric layer.
Abstract: A seating construction with joined seat and backrest parts has a plenum into which is received temperature conditioned air. Coil springs define the plenum and a covering is secured over the springs consisting of, from the inside out, a metal mesh layer, an elastomer sheet with a number of openings, and an air permeable fabric layer. The elastomer sheet behaves as a viscous liquid when subjected to forces and shocks. An alternative to the elastomer sheet is a baglike layer filled with fluid with a number of openings provided to enable passage of conditioned air through the layer.

TL;DR: A modified blanket assembly construction includes rigid edge wall members holding the outer and inner layers separated at a predetermined spacing reducing "pinch-off" between the layers restricting air flow within parts of the cavity or chamber.
Abstract: A blanket assembly has an outer layer constructed of a relatively close weave fabric preventing air flow therethrough. Underneath the top layer is a second layer of material edge connected to the top layer and which is constructed of a material permeable to air, such as relatively thin taffeta, for example. A cavity exists between the two layers which receives pressurized cooled or heated air that passes through the air permeable layer to cool or heat the individual using the blanket assembly. A modified blanket assembly construction includes rigid edge wall members holding the outer and inner layers separated at a predetermined spacing reducing "pinch-off" between the layers restricting air flow within parts of the cavity or chamber. Peltier effect elements are selectively energizable to heat or cool air provided to the blanket assembly cavity.

TL;DR: In this paper, a seat pad and backrest enclose a plenum into which pressurized air is provided from a closely adjacent Peltier air temperature and humidity modifying apparatus (either cooled or warmed).
Abstract: A seat pad and backrest enclose a plenum into which pressurized air is provided from a closely adjacent Peltier air temperature and humidity modifying apparatus (either cooled or warmed). A metallic mesh is part of the seat pad and backrest and warms or cools the user by conduction. Alternatively, the seat pad and backrest can be separate each having its own plenum, and modified air is provided to both via a selectively adjustable proportioning valve. Yet another alternative unitarily incorporates a seat pad and backrest into a chair with a single plenum fed temperature modified air from a Peltier unit mounted on the chair.
