A facade-integrated Multi-Source Heat Pump in combination with a Ventilation System for Heating and Cooling

In refurbishment of multi-family houses heat pumps for heating purpose are rarely used. If in a deep renovation a ventilation unit is mounted, the ducts could be used also for heating. For this reason, a ventilation unit combined with a multi-source heat pump (exhaust and ambient air) was developed, built, tested and simulated. It is suitable for heating and cooling apartments and small buildings with a heating capacity of up to 2.5 kW. With the presented solution often-obtained problems with air heating systems, such as dry air due to high volume flows or overheating of the supply air rooms can be avoided. A simulation study with a calibrated heat pump model was done to proof the concept.
