Humidify: cool while saving

Humidification for comfort and industrial processes
Air humidity is an important parameter for personal comfort in residential and commercial environments; the right level of air humidity guarantees a sense of well-being and productivity in the workplace. In industrial processes, air humidity control is needed to ensure process stability, product quality and quite often compliance with standards in force. 
CAREL products respond to the needs of residential, commercial and industrial applications, with special focus on running costs and energy consumption. Other important features of CAREL solutions for air humidification are simple use and installation, and reliability to ensure continuous service.
Energy savings: evaporative cooling
Air can be effectively cooled by exploiting the evaporation of water atomised into very fine droplets: the change in state, from liquid to vapour, absorbs energy from the air, which is consequently cooled. Evaporation of 100 kg/h of water absorbs 69 kW of heat from the air, for power consumption of less than 1 kW!. In an air handling unit, the supply air can be evaporatively cooled and humidified (direct evaporative cooling, DEC). Alternatively, if the outside air humidity is already high, the exhaust air can be cooled by several degrees without limits in terms of humidity, as it is discharged by the AHU; this cooling capacity, using a heat exchanger, can be used to cool the incoming fresh air with an efficiency that depends on the heat recovery unit used, yet easily exceeds 50%! (indirect evaporative cooling, IEC). All this means lower unit energy consumption and smaller dimensions and capacity of the cooling coil and chiller.
To develop these sophisticated solutions, CAREL has fitted a complete and modern air handling unit in its research centre, to optimise performance in all operating conditions and hence offer customers solutions that are together efficient, complete and easy to use.
