Simultaneous heating and cooling is no longer a rarity in advanced building-operations systems. It is especially buildings oriented to the north and south – as well as applications with great demands for heating throughout the year – that continuously require dual supply of heat and cold over long periods of time.

Until now, cold water was used for cooling needs, and heating systems were employed to furnish hot water, in parallel operations. This arrangement prevented the possibility of exploiting energy-optimization potentials.

The GEA HeaMo system, in contrast, uses heat produced by refrigeration to cover the hot-water requirements of a building. A maximum of effectiveness is achieved when cooling and heating energy must be provided at the same time, in a balanced relationship.
