Energy efficiency in the building sectorEuropean project iNSPiRe:Development of Systematic Packages for Deep Energy Renovation of Residential and Tertiary Buildings including Envelope and Systems
Heat pump:A performance map model is used based on laboratory measurements for hygienicvolume flow (120 m3/h) including transfer function for modelling the dynamicbehavior (when heat pump or condenser switches on and off):
• Concept: an exhaust air heat pump combined with mechanical ventilation with heat recovery is presented, and tested in a demonstration building
• Simulation models are developed, calibrated and validated using on-situ monitoring data
• Building and system simulations are performed to prove the feasibility of the concept and to investigate its performance
– Varying the set point temperatures of the investigated flat and its neighbouring flats:
• Total SPF (including MVHR) varies between 2.6 and 4• System SPF (excluding MVHR) was 2.1 with moderate use of post heater• SPF of the micro-HP varies between 3.1 and 3.6
– The influence of minimum operation time of the compressor is negligible on the performance of the system but may increase the life time of the compressor
