초록 ▼

A vehicle has a cabin and an air conditioning system for cabin air, the system including a ventilator and a compressor. With a view to energy consumption and the time taken for reducing the cabin air temperature to an acceptable value when the vehicle has been left stationary in full sun, the air conditioning system is used for reducing cabin air temperature in three successive stages. These stages are controlled in response to the internal temperature Ti and the external temperature Te, as follows: (a) when Ti is much greater than Te, for example due to heating by the sun, the air in the cabin is renewed by direct admission of external air to the cabin at a high flow rate; (b) when Ti is close to Te, the air conditioning unit is started on a high power setting, using recycled air, so as to bring the cabin temperature rapidly down to a value approaching the required value; (c) once the required cabin temperature is reached, the air flow rate and the working speed of the compressor are both reduced to normal levels, remaining in a recycling mode.

A method of reducing cabin air temperature in a vehicle comprising a cabin, and associated with the cabin an air conditioning means comprising a compressor for a refrigerant fluid, a fan for delivering a stream of air into the cabin and an evaporator for transferring heat from said stream of air to said refrigerant fluid, wherein said method includes the steps of: detecting the temperature of the internal air in the cabin; detecting the temperature of the external air outside the cabin; and controlling the apparatus, in response to said detected temperatures, in three successive stages as follows: in the first stage, driving the fan so as to deliver external air into the cabin when the internal temperature exceeds the external temperature by at least a predetermined limiting amount; in the second stage, driving the compressor in a first compressor regime when the condition for the first operating stage is absent but the internal temperature is greater than a predetermined threshold value; and in the third stage, driving the compressor in a second compressor regime such that energy consumption and the heat exchange capacity of the evaporator are reduced as compared with the second stage, when the conditions for the first and second stages are absent, further comprising the step of interrupting the operation of the apparatus when the vehicle remains stationary after a predetermined period of time.
