The present disclosure simplifies the H-bridge circuit of the direct current motor for driving the damper (door) that switches the air passages in the indoor unit of an air conditioning device. The control device for an air conditioner that takes in inside or outside air and conditions the air inside an air conditioning unit using an evaporator and a heater core is provided with: a first actuator and a second actuator that drive the multiple dampers installed inside the air conditioning unit for switching the air passages; and three half-bridge circuits that control the first actuator and the second actuator sharing one of the half-bridge circuits. Of the multiple dampers, the first actuator is connected to the inside/outside air switching damper. Of the multiple dampers, the second actuator is connected to at least one air mix damper.

Control device for air conditioner

A thermoelectric conversion device and a manufacture method thereof are provided. The manufacture method includes an electrode board stamping process, an insulating frame molding process, a punching process, an element fixing process, a bending process and an insulating frame integrating process. Band-shaped plate members which function as heat radiating fins and heat absorbing fins and are integrated with insulating frame members are respectively folded-back in such a manner that the folding-back directions of the band-shaped plate members are alternately reverse to each other in the longitudinal direction of the band-shaped plate member. The insulating frame members are joined to each other to be arranged substantially in line, to construct an insulating frame unit. Thus, the component number and the assembly labor can be reduced, while the manufacture quality and the product quality can be improved.

An automotive seat air-conditioning system includes a vehicle seathaving a seat portionused by an occupant and a seatbackagainst which the occupant rests his/her back, and a blowerfor sucking in the air-conditioning airflowing in the compartments. Further, the air-conditioning airis sucked in by the blowerfrom the air inletformed on the surface of the seatback. At the same time, the air-conditioning airis blown out from a surface portion of the vehicle seatother than the air inlet
