  • Apparatus and method for the environmental control of vehicle interiors
    Patent number: 5810078
    Abstract: An apparatus and method for controlling the air condition and heating within a vehicle interior compartment, in which the apparatus 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 apparatus further includes a control unit (46) which is operative to calculate a theoretical interior temperature T.sub.I based only upon information from sensors (26, 29) sensing the external heat load of the compartment, a sensor (27) sensing the temperature of the air supplied to the compartment and fan current representative of the volume of air supplied to the compartment. The control unit (46) compares this theoretical interior temperature T.sub.I with the preset temperature T.sub.ISet , calculates the difference .DELTA.T.sub.I, and then controls air flow and mixed temperature T.sub.M to readjust or maintain the interior temperature within the compartment (19) at the preset temperature T.sub.ISet.
