High performance air conditioning

Emerson Network Power has extended its Himod series of high performance air conditioners available under the Liebert Hiross brand with the introduction of Himod M. Designed for all environments requiring high dissipation of sensitive heat, the series will soon be completed with the introduction of Himod L. With cooling capacities between 25 and 80 kW, the Himod M is ideal for a range of applications including hospitals.

Available in either upflow or downflow configuration, the Himod M range also includes “displacement” versions that deliver air at relatively low speed across the floor, thus creating a temperature gradient in the room, from floor to ceiling. To meet the very highest precision requirements, some Himod M models are available in a “constant” version. These units, all with direct expansion, are equipped with a hot-gas post-heating device with modulating features. By utilising a special control algorithm, the air treatment is varied continuously, thus avoiding the typical on-off cycle of the compressor.
Himod M can be supplied in a freecooling version, providing great benefits in terms of power saving. In cold climates, this feature provides cooling capacity by exploiting the outdoor winter temperature, without using the compressor. Depending on climate conditions, freecooling units can achieve up to 30% energy saving.
