Abstract
Disclosed is a ventilation arrangement for buildings with heat removal from an exhaust-air flow (LAb) discharged from the building and/or from a fresh-air flow (Lzu) supplied to the building, the arrangement having a heat pump which has a coolant/water heat exchanger (WW) with a mass flow controlled by the water system and having a coolant/air heat exchanger (LWzu, LWAb) serving the fresh-air flow (Lzu) and the exhaust-air flow (LAb), the coolant/air heat exchanger (LWzu, LWAb) being connectable in series to the coolant/water heat exchanger (WW).
Claims21
A ventilation arrangement for a building with heat removal from an exhaust-air flow discharged from the building and a fresh-air flow supplied to the building, comprising:
- a heat pump including a coolant/water heat exchanger, a coolant/air heat exchanger serving the exhaust air flow and a coolant/air heat exchanger serving the fresh-air flow;
- and wherein
- the coolant/water heat exchanger is provided on a water side of the heat pump with a controllable mass flow of water and the coolant/air heat exchangers are each connectable in series to the coolant/water heat exchanger to receive the controllable mass flow of water.
