An air blower unit operates with reduced noise while providing a stream of warmed air. The blower unit includes a housing with an inlet at a first end and an outlet at a second end. A support positions the housing above a support surface such that the inlet points toward the support surface, and the outlet does not point away from the support surface. A rotatable blower creates an airstream by flowing air into the housing through the inlet and out of the housing through the outlet. The outlet is coupled to a delivery conduit having an elbow that absorbs some noise from the blower, and reflects remaining noise downward. The delivery conduit may be connected to a convective thermal blanket, for example. A motor, mechanically linked to the blower, rotates the blower and resides in the housing upstream of the blower. A heater, interposed between the blower and the motor, heats the fluid stream as it passes the heater.

A climate control system having two or more stages of cooling operation or heating operation is provided for supplying conditioned air to a plurality of zones within a space, where the climate control system comprises a plurality of controllable zone dampers for controlling the supply of conditioned air to each of the plurality of zones, and a plurality of zone temperature sensors for periodically sensing temperature at preset intervals and transmitting sensed temperature information when the temperature of the zone has changed by more than a predetermined amount. The climate control system further comprises a thermostat that is adapted to initiate operation of the circulating air blower and the cooling system at less than full capacity when at least one zone temperature sensor transmits a sensed temperature that differs from the set point temperature by more than a specific amount, wherein the thermostat switches the circulating air blower and cooling system to full capacity operation when either the cooling system has operated at less than full capacity for more than a predetermined time or when more than a predetermined number of zone temperature sensors transmit sensed temperatures that differ from the set point temperature by more than a specific amount.

A vehicle seat includes a seat back and a head rest. The seat back has an air blower that is capable of aspirating air, and a blower duct that is capable of introducing the aspirated air toward a blowhole formed in the seat back. The head rest has a head rest main body and a stay attached to the head rest main body. The stay is inserted into the seat back, so that the head rest main body is vertically movably attached to the seat back. The air blower is disposed on the seat back such that a rotation center thereof can be positioned above the level of a terminal end of the stay that is moved to a lowermost position.
