According to EN14825, the highest Energy Efficiency Class for Heat Pumps is A+++ with a SCOP=3.75 (high temperature) -4.38 (low temperature). With a SCOP=3.8÷6.5 (of the refrigerant circuit) and a COPnet of the whole system SCOPnet= 5÷15, max.e3 is far ahead of the competition.
*SCOPnet- seasonal efficiency of a unit in active heating mode, without supplementary electric heaters which is determined from mandatory conditions given in this EU standard and used for marking, comparison and certification purposes.
COPnet = Qrotory exchanger + Qheat pump
1. Qrotory exchanger - recovered heat in the rotary heat exchanger (kW)
2. Qheat pump - heating capacity of the condenser of the heat pump (kW)
3. Nfans - energy consumption of both (supply and exhaust) fans (kW)
4. Ncompressors - energy consumption of the compressors (kW)
