Hello,

I am wondering if anyone have modeled the waterside system with air-cooled
heat pump with supplementary condensing boilers.
We have packaged heat pump modules provide heating and cooling water on
demand by modulating the individual modules and heating/cooling control
valves. Heat pumps are sized to meet cooling demand. The condensing boiler
starts for heat rejection into the heating water system when the heat pump
chiller cannot maintain the supply water setpoint of 135F.

Thank you for your help in advance,
