[TRNSYS-users] Control signal for GSHP

[metkell yebiyo]

Dear TRNSYS users,

My name is Metkel, I am a researcher at London South Bank University, I am currently trying to simulate a GSHP system. the GSHP is controlled by the outside temperature, if the outside temperature is less than 14 then a control signal  tells the GSHP to run in heating mode, if the outside temp is greater than 18 then the control signal tells the GSHP to run in cooling mode.

However I couldn't figure out how to write the equation to the following please.
1. based on the outside temperature to send a signal to the heat pump.
2. based on the outside temperature to retrieve the cooling or heating load of the building from
    type 9a which contains the building load.
3. based on the outside temperature to also send a signal to the circulation pumps to switch them
   on or off accordingly.

Any suggestions would be much appreciated please.


Regards,
Metkel
