Abstract
Components of an elevator system are cooled using natural convective airflow in conjunction with thermoelectric heating and cooling. Rising air within the hoistway is funneled into a cold air duct (20) and a warm air duct (22). As air flows vertically upward through the cool air duct (20) and the warm air duct (22), a thermoelectric module (14) cools air in the cool air duct (20) and heats air in the warm air duct (22). The cool air stream in the cool air duct (20) is circulated past the elevator component (12), and is drawn upward into a common exhaust duct (28) by the faster flowing warm air stream in the warm air duct (22).
