Dear Ratnalee,

Thank you for the explanation. I believed so, but it was not clear from TRNSYS documentation.

The type680 si located in HVAC TESS library under single-effect absorption chiller hot-water fired.

Best regards,

Emilia Visek

Emilia,

 

For the absorption chiller models I believe the rated COP to be supplied as a parameter is thermal COP (Q_{cooling output}/Q_{heat input to generator}). In the COP output from the chiller model however, the electricity consumed by the chiller for the operation (for pumps etc.) is taken into consideration based on the auxiliary electric power (Q_aux) supplied as one of the parameters. Thus the output COP = Q_{cooling output}/(Q_{heat input to generator +} Q_aux).

 

By the way, where is this Type 680 located? I am aware of Types 676 to 679, Type 681, and Type 107 for absorption chillers.

 

Thanks.

Dear all,

The COPrated from type680, is thermal or electrical COP?

Thank you,
