COP vs COPnet

COP is the basic parameter which describes the energy efficiency of each air conditioning system like split air conditioners, VRF and chillers. But when we have a hybrid system this parameter is partialy inacurate, because recovered energy from the passive system won’t be taken into account. Also as a part of air handling equipment it is a must the fans, which extract the enrgy from the air to be part of the equation as energy consumer as well. For these reasons in the far 2011 Damvent was the first company to establish and introduce the parameter COPnet! Which in full scope would evaluate the total energy efficiency of the hybrid AHUs. In the video we will explain you how important and beneficial effect has passive stage recovery on heat pump work and why COPnet >10 is not surprise anymore.
