Experimental measurements for a new heat pump desiccant dehumidifier during a summer session

It is well known that the energy consumption for summer air conditioning tends to be an ever growing fraction of the energy need for the indoor environment. Recently a new equipment for dehumidification was put onto the market. It is a self regenerating liquid desiccant cooling system able to dehumidify, heating or cooling the ambient air by an electric heat pump that is a part of the equipment. A commercial/industrial treatment unit of this type was installed in a new building of the Vicenza hospital, and a data logging system was set up to monitor several parameters of this interesting device. Collected data show the performances of the device, both in terms of COP and temperature-humidity control. These data were of great help for the understanding of the unit’s behaviour.
