    摘要: The invention proposes an air conditioning system for motor vehicles which is fitted with an injection computer and an electronic control device. The system comprises a first measuring member suitable for supplying a value relating to the pressure of the fluid at a first point in the air conditioning circuit which is situated between the outlet of the expansion member and the outlet of the evaporator, and a second measuring member suitable for supplying a value relating to the pressure of the fluid at a second point in the air conditioning circuit which is situated at the inlet to the compressor. The electronic control device makes use of the solution of an equation which relates the mass flow rate of the refrigerant fluid to the difference in pressure between the first point and the second point in order to calculate an estimate of a magnitude relating to the refrigerant fluid.

    摘要: The invention proposes an air conditioning installation furnished with an injection computer (42), with an air conditioning apparatus and with an electronic control device (401). The installation furthermore comprises measurement facilities making it possible to establish values relating to the temperature of the external air stream at the inlet of the condenser, to the pressure at the outlet of the compressor (123), and to the pressure at the inlet of the compressor (122). The electronic control device (401) implements the solving of a linear equation, relating the mass flow rate of the refrigerant to the values measured by the measurement facilities so as to calculate an estimate of a quantity relating to the refrigerant. On the basis of this quantity, the electronic device can estimate the power absorbed by the compressor (14).
