Hi,
I'm doing a 20 years simulation with EnergyPlus because i have to evaluate the substitution of a geothermal heat pump.
I have to simulate present heat pump for first 10 years and new heat pump for following 10 years.
I build a weather file with 20 years, starting from 2006, and I tried to write an EMS program to control the two heat pumps but EnergyPlus crashed after some years of simulation.
 
Here the EMS program:
IF Year < 2016,
SET OldHeatPump_Cooling_Actuator = on,
SET OldHeatPump_Heating_Actuator = on,
SET NewWaterHeatPump_Cooling_Actuator = off,
SET NewWaterHeatPump_Heating_Actuator = off,
ELSE,
SET OldHeatPump_Cooling_Actuator = off,
SET OldHeatPump_Heating_Actuator = off,
SET NewWaterHeatPump_Cooling_Actuator = on,
SET NewWaterHeatPump_Heating_Actuator = on,
ENDIF
 
How can I do it? Thanks.
