[EnergyPlus_Support] How to control the system with UnitaryHeatPump:WaterToAir

[Chen LUO <richardluo88@xxxxxxxxxxxxxx>]

Hello,

I am trying to simulate a model with condenser system, which means the dx cooling coil connected with a cooling tower.

So I choose UnitaryHeatPump:WaterToAir to realise it. (So I have to turn off the heating coil and supplemental coil)

But I find it's hard to give all the parameters for such a component. And I can only use fan:onoff and there is no water coil controller so that I can't control the supply temperatures properly.

Do you have any suggestions for simulating such a model? How can I put in all these parameters in?

And most important, how can I get it better controlled?

(I already build the model, it run successfully. But the zone temperature changes a lot and I can't get the unmet load hours down to 300 hours.)

Looking forward to your reply!

Thanks.

Chen
