Revision history [back]

Hi. Everyone.

Im Uni Student from South Korea.

I made EnergyPlus 5 zone model with one vav unit in each zone. and one chiller, cooling Tower, boiler.

I connected every airloop, waterloop node, and modified severe errors.

And my simulation model runs successfully.

But I got problem that energy consumptions of chiller, cooling tower are zero all time. And indoor air temperature is not controlled to the setpoint temperature.

Although set to Fan:variablevolume, only the supply fan consumes the same energy throughout the simulation time.

I checked all HVAC availablity schedules, and compared my model with example files.

But energy consumptions of chiller, cooling tower, boiler are still zero.

I know my model is not perfect, so I want to know why model cause this problem.

Would you help me? Please
