PURPOSE:To ensure the balanced state of heat load in a compartment by adjusting the temperature of air discharged into the air conditioner region of the auxiliary air conditioner in response to solar radiation. CONSTITUTION:A solar radiation sensor 9, which is arranged near the air conditioning region of the auxiliary air conditioner 2 and generates electric signals corresponding to radiation from the sun, a cooling-degree sensor 10 generating electric signals corresponding to the actual degree of cooling of the auxiliary cooling device 3, and an electric circuit 11 adjusting the electric energizing of an electromagnetic opening and closing valve 4 in response to electric signals from both sensors 9, 10 are provided. The electric circuit 11 adjusts continuously the ratios of the opening and closing times of the electromagnetic opening and closing valve 4 in response to the actual degree of cooling of the auxiliary cooling device 3 and radiation from the sun. Accordingly, the balanced state of heat load in the compartment is kept, and indoor amenity is improved. |
