[Equest-users] Problem in simulate a heat-pump chiller with cooling tower

[Jimmy Law]

Thanks Brain. I tried your advice and it can be excellent if I was modelling a proposed building. However, I am modelling an existing building with a fluid cooling tower. The hear pump chiller could not be connected to this CW loop if I make it connected to a 2-pipe loop. So is there any solution for that? 

AndI am still not quite sure which chiller type should be use in this case, since it is a electric screw chiller. Is it correct that it shoule be better choose Loop-Loop Heat Pump or just Heat Pump to make it connected to all CHW, CW and HW loops? 

Thank you.

Regards, 
Jimmy

I would try modelling it as a heat pump chiller connected to a 2-pipe loop which controls when it is in heating or cooling mode.

Dear all, 

Recently I am trying to do heat-pump screw chiller with a fluid cooling tower for a commercial building in a sub-tropical area, which means it will mostly run like a normal chiller and will supply HW in 40 degreeC for heating in just two or three month. Meanswhile, whenever I chose Loop-Loop Heat Pump and just Heat Pump for chiller type, the chiller obviously can not be connected to the CW loop but only to LAKE/WELL loop. Can anyone please give me any advice to solve this issue and simulate this system?

Thank you!

Regards, 
Jimmy
