The facility (1A) includes at least two treatment devices (2) each with an exchange chamber (20) intended to contain a liquid bath in the bottom part and at least one injection line (21). An aeraulic means (4), creates by suction or by blowing, simultaneously and in parallel for each treatment device (2), an incoming gas stream (F) originating from outside the exchange chambers (2) and passes through the discharge opening of the injection line (21) by being introduced into the liquid bath contained in the bottom part of the exchange chamber (20), below the surface (S) of said liquid bath. The exchange chambers (20) communicate hydraulically with one another so that when the aeraulic means (4) are shut down, each exchange chamber (20) is suitable for containing or contains, in the bottom part, an initial volume (V.sub.initial) of liquid, with an initial liquid level (H.sub.initial) that is identical in all the exchange chambers (2).

In a system for air-conditioning interior spaces of a building which are connected via at least one exhaust air duct, one or more interior spaces are provided with an air-conditioning unit which has a inlet line of outdoor air, which supplies inlet air or circulating air to the interior space or spaces, and which is connected to a fluid circuit of a heat pump.

The second temperature sensor measures a temperature of one of the water pipes which is connected to an outlet of the heat exchanger. The controller controls an opening degree of the water regulation valve, based on a difference between the temperature measured by the first temperature sensor and the temperature measured by the second temperature sensor.
