Thank you for your answer Angel,

1) Yes but I have an heating district system with more than one component
(boilers, tanks, absorption chiller for summer operation, ...) I don't know
if I have to change the type of heat exchangers linked to the buildings
(for summer operation)...

2) I don't know how to model a control system... I have to change the
operation from winter to summer and the opposite. Could you help me?

Thank you again for your availability,

Kind Regards,
Laura
