Energy recovery

All fluids that have a higher amount of heat than the original due to the treatment by human activity can be used as heat sources. In the industrial setting a lot of activities make water at very high temperatures and disperse in the warm air environment.

By their nature, these sources do not allow optimal utilization, as their availability is not certain but predominantly intermittent. It is also often exuberant in relation to the heat pump capacity. In the first instance, you can consider using an accumulator to solve or resize the problem. Rational handling of the accumulator allows optimal utilization in the partial load sector and the limitation of power points.

The COMPOUND heat pumps allow you to fully utilize all the waste heat, resulting in an important economic savings. Indeed, their technology naturally incorporates the ability to test the availability of waste water and use them completely before they are dispersed.

The first accomplishments was development in the industrial field in order to recover the heat losses derived from the production processes. Afterwards the technology has evolved and now this system uses intelligent optimization software that can select and implement energy saving strategies

A real example in the residential field

A particularly interesting source of heat is the drainage water (black waters), mainly due to its relatively high temperature. Here is what follows:

  • Only indirectly usable due to pollution.
  • Often the amount is too small for profitable exploitation.
  • Authorization is required for public wastewater.
