How far do you go to calculate the actual COP of an infinately veriable system ?

It can be done.

The UK Government has an energy efficiency scheme that allows a tax break on certain eligible heat pump products, including VRF. (The Enhanced Capital Allowance scheme – ECA for short).

You can use their calculator tool to work it out.


http://www.eca.gov.uk/etl/default.htm

You can search eligible products by manufacturer and model, including the products of those VRF manufacturers who have submitted products for approval – this also includes VRF and there is an excel calculator that you can download with a selector page that you can build up a system with the outdoor unit and the selection of Indoor units of your choice. It will work out various combinations of VRF indoor units and display the CoP and EER plus whether it’s eligible for the tax break.

All the main VRF companies are represented.



Click ‘Find ETL Product.
Select ‘Heat Pumps – Split and Multi split, including VRF’ in the drop menu
Select your manufacturer.
Select the VRF sheet that you see ( If they don’t have one it will be absent).
Read the instructions for use - then do what it says.
