[EnergyPlus_Support] problems with HEAT EXCHANGER:HYDRONIC:FREE COOLING

["Miguel Angel Pascual" <mapascual@xxxxxxxxx>]

Dear Group:

 

I would like to use the HEAT EXCHANGER:HYDRONIC:FREE COOLING model for free
cooling with GSHP but it is not working. In my simulation the following
things happens:

 

-          The HEAT EXCHANGER:HYDRONIC:FREE COOLING disables the
HeatPump:WaterToWater:EquationFit:Cooling 

-          There is massflow throw the plant side of the HEAT
EXCHANGER:HYDRONIC:FREE COOLING

-          There is NO massflow throw the condenser side of the HEAT
EXCHANGER:HYDRONIC:FREE COOLING 

-          The result is NO cooling and NO free-cooling

 

I have checked the connections with the example included
FreeCoolingChiller.idf but this example is not working also (there is no
cooling at all).

 

Can anybody check this?

 

 

Thanks in advance.
