[en] This paper is based on the first Belgian case study developed in the frame of the
IEA-ECBCS annex 48 project. It concerns an industrial building in which
simultaneous cooling and heating demands subsist all along the year: boilers and
chillers are working in parallel and nothing is currently done to recover the
condensers heat.
In such existing building, one of the first energy retrofit to be considered consists in
installing a heat pump between the chillers condensers and the hot water distribution,
or in making the condensing temperature compatible with heating requirements.
The COP of this heat recovery process is expected to overpass 3.
Combined with the efficiency of a modern TGV power plant (~55%), this COP makes
heat pumping using less than one half of the primary energy consumed by the best
boiler available.
And the CO2 emission is reduced in proportion…
