[TRNSYS-users] Question on Type 15-1 (TMY Weather file)

[David BRADLEY]

Mohammad,
  My apologies for the delay in getting back to you. You can use 
instances of Type11 to mix two flows into a single flow before passing 
it to the heat pump. You can then use another instance of Type11 to 
split the flow from the heat pump back to the two tanks.
kind regards,
  David
