<p>An apparatus and method for controlling the air condition and heating within a vehicle interior compartment. The system includes a fan (13), heat exchangers (14, 15), temperature sensors (26, 27, 28) and a solar sensor (29) and temperature control (47) for setting a desired temperature. The system includes a control unit (47) which is operative to calculate a theoretical interior temperature TI based only upon information from sensors (26, 29) sensing the external heat load on the compartment, a sensor (27) sensing the temperature on the air supplied to the compartment and blowerfan current representative of the volume of air supplied to the compartment. The control unit (47) compares this theoretical interior temperature TI with the preset temperature TISet, calculates the difference ΔTI, and then controls air flow and mixed temperature TM to readjust or maintain the interior temperature within the compartment (19) in level with the preset temperature TISet.</p> |
