<p>The unit has a heat exchanger-evaporator including parallel circuits that include regulator valves. An air circuit has a temperature probe provided downstream of the evaporator and connected to a control unit to control the valves to regulate a flow of refrigerant e.g. hydrofluorocarbon. A pressure probe is connected to a regulating unit for regulating speed/power of a main fan e.g. centrifugal fan, so as not to exceed a maximum raised pressure at an air outlet. A refrigerant circuit is connected to a regulating unit to regulate a mass flow rate of refrigerant drawn in by a screw compressor. An independent claim is also included for a method for conditioning air.</p> |
