Abstract: An air-conditioning unit including an air circuit with an air inlet, a main fan and an air outlet designed to be connected to a chamber, preferably via one or more flexible ducts, and a refrigerant circuit including a heat exchanger/evaporator positioned in the air circuit to cool the air by evaporating the refrigerant, a compressor and a condenser for condensing the refrigerant before it is returned to the heat exchanger/evaporator. The heat exchanger/evaporator includes several parallel circuits each having at least one regulator valve. The air circuit also includes a temperature probe downstream of the heat exchanger/evaporator and connected to a controller which controls the regulator valves to regulate the flow of refrigerant, and a pressure probe at the air outlet and connected to a regulator for regulating the speed and/or the power of the main fan so as not to exceed a maximum raised pressure at air outlet.
