A system for controlling the temperature climate in a variable temperature occupant seat

摘要

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 hi 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 ah" surrounding the occupant as well as the temperature of the conditioned air directed to the occupant. The controller is configured to automatically regulate the operation of the Peltier modules and/or each main fan according to a temperature climate control algorithm designed both to maximize occupant comfort during normal operation, and minimize possible equipment damage, occupant discomfort, or occupant injury in the event of a heat pump malfunction.
