  • Patent number: 7255130
    Abstract: A control valve (10) for a fluid circulation circuit comprises a body (12) which is equipped with a fluid inlet (18) and at least two fluid outlets (20, 22 and 24) and which delimits a cylindrical housing for an adjusting member (26) able to rotate about an axis of rotation (XX) and to adopt various angular positions in order to control the distribution of fluid through the outlets. The body (12) comprises an end wall (14) into which the fluid inlet (18) opens and a cylindrical side wall (16) into which the fluid outlets open at axial heights and at angular positions that are chosen with respect to the axis of rotation (XX). The rotary member (26) comprises a truncated end (38) facing toward the end wall (14), this making it possible to have control over the fluid outlets using a law defined as a function of the angular position of the rotary member in the valve body.

  • Patent number: 7003968
    Abstract: 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).
