HI
I have a project where I need a heat pump system VRF or split with a COP of 6 or more!
The system will only be used for heating.
I have tried the big names and the highest they can offer is COP 5.5 - 5.7
This is with an ambient of 15°C and room 19°C.
I can fiddle with temperature day numbers to get an artificial SCOP but I need a base COP for approval.
Question is;
Does anyone know of a system (without hot water heat recovery etc) that can get to this?
Am I missing something in the selection process that will boost the COP? (e.g oversized evaporator)
Thanks
