In the project we working on, there is a water cooled electrically operated chilling package.

This chiller however is used as chiller/heater, whereby during the heating period it is providing heat while utilizing as an evaporator energy source a closed ground loop cirquit.

Please advice how such equipment should be addressed to Table 6.8.1.c, or should it be as non-regulated, meaning its COP is to be estimated based on the operating temperatures difference between the condenser and evaporator and of course upon confirmation from the manufacturer.

Your advice is highly appreciated.
