摘要： PURPOSE:To prevent condensed water from being evaporated and blown out inside the room of an automobile, when a cold heat source passing mode is changed over to a warm heat source passing mode by means of an operation switch, by allowing the change of mode only when a confirmation signal is input. CONSTITUTION:An interior unit 1 comprises a blower unit 2, a first unit 3, and a second unit 4. In the blower unit 2, a blower 9 is provided, and inside the first unit 3 an interior first heat exchanger 11 is arranged, and inside the second unit 4 an interior second heat exchanger 12 and auxiliary heaters 13, 14 are arranged. When a cold heat source passing mode is changed over to a warm heat source passing mode by means of an air-conditioner switch 43 (not shown), and only when the operation signal of a confirmation operation switch 44 is input in a microcomputer 47 and also the vehicle speed is zero, the mode change is allowed. As a result, clouding of the windowpanes during traveling can be previously prevented.

摘要： PURPOSE:To provide an air-conditioner for an automobile which can be improved in respect of both the durability of a compressor and the coefficient of a result. CONSTITUTION:An indoor or outdoor air is introduced into a compartment via a duct 7 through operation of a blower 6. Within the duct 9, an indoor heat exchanger 8 and electric heater elements 9a, 9b are disposed. In the heating operation, during a time period in which a blower switch is in other modes than the Lo mode, a passing air is heated through operation of the indoor heat exchanger 8 in the duct 7 and simultaneously is also heated by the energized electric heater elements 9a, 9b. Further, when the blower switch is in the Lo mode, i.e., when an amount of air blown by the blower 6 is smaller than a specified amount, heating of air by the indoor heat exchanger 8 in the form of a refrigeration cycle is not conducted but heating thereof by energization of the electric heater elements 9a, 9b is only conducted.

摘要： PURPOSE:To perform the most suitable person chasing operation and a swinging operation by a method wherein the second direction changing control means as well as the first direction changing control means may repeat an operation in a direction of a sensing region of a person sensing means in a predetermined direction at a speed different from a changing speed in the sensing region of the person sensing means with the first direction changing control means. CONSTITUTION:A controller 20 (the first direction changing control means) may control a stepping motor 15 for directing to a person a direction of sensing regions of ultrasonic sensors S1 and S2 and a cold air blowing port duct 8 in response to a sensing signal of the ultrasonic sensors S1 and S2. The controller 20 (the second direction changing control means) may repeat to operate the cold air blowing duct 8 in a direction in the sensing region of the ultrasonic sensors S1 and S2 at a speed different from a changing speed in the sensing region of the ultrasonic sensors S1 and S2 in response to the sensing signals of the ultrasonic sensors S1 and S2 under an oscillating operation mode of the following-up and oscillation selection switch 17. With such an arrangement, it is possible to perform the most suitable person chasing operation and the oscillating operation.
