    摘要: A method for controlling a heating, ventilation and air-conditioning (HVAC) system having an air vent associated with a window for blowing an air flow of controlled temperature thereon; the HVAC system having a refrigeration unit with a compressor and an evaporator, and blowing means for forcing air over the evaporator to the air vent. The method includes a first step (a) of activating the compressor while deactivating the blowing means during a first period for condensing moisture of the air contained in the HVAC system. The method includes a further step (b) comprising, at the expiry of the first period, activating the blowing means and keeping the compressor active during a second period for sufficiently reducing the dew-point temperature of air blown by the HVAC system, and deactivating the compressor at the expiry of the second period.

    摘要: The invention relates to a method for estimating a heater-core air discharge temperature of an HVAC system. According to the invention, the method uses a model of the heat exchanger. This heat exchanger efficiency model maps a heat exchanger efficiency to a set of actual operating parameters by generating a heat exchanger efficiency coefficient based on said second set of actual operating parameters.
