Substitution of a geothermal heat pump
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.
