Dear Trnsys Users, I have to model a solar energy assisted heat pump
system for hot water supply (See attached image of the System). The heat pump
is supposed to work only if the water temperature of the collector output is
not high enough (green circuit), otherwise the outlet water flow of the
collector should bypass the heat pump (red circuit). The heat pump has to work
with a refrigerant other than water. Since I’m using Trnsys for the first time I
have some questions about modelling the heat pump: Which Type (also from TESS-Library) should I use to
model the heat pump? At the moment I’m using Type 20. How can I control the input # 5 “Heating
control function” of type 20? Is it calculated internally or has it to be
connected with an Output from the solar collector (Output # 1, Type1b, “Outlet
Temp”??). I would be very thankful for some help Best regards, Julian M.Sc. Student Technical Universidade Federal de Santa Catarina, Brazil |
