Abstract
The invention proposes an air conditioning installation furnished with an injection computer (), with an air conditioning apparatus and with an electronic control device (). 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 (), and to the pressure at the inlet of the compressor (). The electronic control device () 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 ().
