Benefits of technology
The present invention is an air conditioner with two air passages, two desiccant devices, a heat source, a heat supplier, a temperature sensor, an airflow controller, and a controller. The first air passage has a first inlet and a first outlet, and the first desiccant device is placed in this passage. The second air passage has a second inlet and a second outlet, and the second desiccant device is placed in this passage. The heat supplier provides heat to the first desiccant device to regenerate it. The system heat source temperature sensor detects the temperature of the heat source. The airflow controller regulates airflow in both air passages, and the controller controls the airflow controller based on the temperature of the system heat source detected by the sensor. The technical effect of this invention is to provide an efficient and effective air conditioning system that utilizes desiccant devices for humidity control and a heat source for regeneration, resulting in improved air conditioning performance and energy efficiency.
Problems solved by technology
Therefore, air having a high temperature for regenerating the desiccant rotor is not generated, so that the desiccant rotor cannot be regenerated for repeated dehumidification.

Embodiment Construction
[0027]The following will describe an air conditioner according to a first preferred embodiment of the present invention with reference to FIGS. 1 through 6B.
[0028]Referring to FIG. 1, there is shown an air conditioner 20 mounted to an electric vehicle 10. An electric motor 11, an inverter 12, an electric control unit (ECU) 13 and an electric vehicle air conditioner (hereinafter referred to merely as “air conditioner”) 20 are disposed in the front of the vehicle 10. The electric motor 11 serves as a power source for driving the vehicle 10. The inverter 12 converts electric power for supplying the electric power to the electric motor 11. The ECU 13 controls the operation of various devices of the vehicle 10, such as the inverter 12 and serves as a controller. The inverter 12 is connected electrically to the electric motor 11, the ECU 13 and the air conditioner 20 for supplying electric power. A battery 14 is mounted in the rear of the vehicle 10. A first power line 15 is arranged in t...

An air conditioner includes first and second air passages, first and desiccant devices, a system heat source, a heat supplier, a system heat source temperature sensor, an airflow controller and a controller. The first and second air passages are communicable with a space to be air conditioned. The first desiccant device disposing in the first air passage has a first desiccant material. The second desiccant device disposed in the second air passage has a second desiccant material whose temperature for regeneration is higher than the temperature for regeneration of the first desiccant material. The heat supplier supplies heat generated by the system heat source to the first desiccant device for regenerating the first desiccant material. The airflow controller regulates airflow in the first and second air passages. The controller controls the airflow controller based on the temperature of the system heat source detected by the system heat source temperature sensor.
Description
BACKGROUND OF THE INVENTION[0001]The present invention relates to an air conditioner for a vehicle and a method for controlling of the air conditioner.[0002]A conventional air conditioner for a vehicle is disclosed in Japanese Patent Application Publication No. 2004-177074. Referring to FIG. 12, the air conditioner has a first air passage 107, a second air passage 108, a first desiccant rotor 101, a second desiccant rotor 102 and a sensible heat exchanger 103. The first air passage 107 includes a suction passage 105 and a discharge passage 106. The first desiccant rotor 101 has a first dehumidifier 121 in the suction passage 105 thereof and a dehumidifier-cooler 122 in the discharge passage 106 thereof. The second desiccant rotor 102 includes a second dehumidifier 123 in the suction passage 105 thereof and a regenerating part 124 in the second air passage 108 thereof. Air flowing from the vehicle interior is dehumidified in the first dehumidifier 121 and the second dehumidifier 123,...
