[Bldg-sim] ground coupled heta pumps in passive building

[leen peeters]

Dear all,

has anyone curves on the part ;load performance of a brine water heat pump
with invertor technology?

We are considering applying this technology in a NZEB renovation (
www.zehr.be), but most available models are oversized. The smallest has a
nominal output of 10kW, and can modulate down to around 3kW. We will use it
in winter to heat and produce sanitary hot water when the solar thermal
system does not produce enough.

Thermal buffering can be done in the buidling structure (floor heating) and
with a tank.

Estimated peak heating load is around 4 to 5 kW for house heating, normal 4
person family demand for sanitary hot water.

Thanks for any suggestions!

Leen
