PCT No. PCT/SE93/00103 Sec. 371 Date Aug. 10, 1995 Sec. 102(e) Date Aug. 10, 1995 PCT Filed Feb. 11, 1993 PCT Pub. No. WO94/18021 PCT Pub. Date Aug. 18, 1994An 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 TI 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 TI with the preset temperature TISet , calculates the difference DELTA TI, and then controls air flow and mixed temperature TM to readjust or maintain the interior temperature within the compartment (19) at the preset temperature TISet.
