Water condenser low temperature, chiller heat recovery

edit

I'm using DesignBuilder, I think the connection is right: https://www.dropbox.com/s/13mi897zrqh...

I adjusted the water flows and the design temperature of the HR loop, the condenser loop and the Auxiliary loop and also the design leaving condenser temperature of the chiller.

I got a better result (https://www.dropbox.com/s/85uggnbs4xz...), now the leaving chiller condenser temperature is about 30°C so the Tank temperature is between 28°C and 34°C. Unfortunately, the condenser loop is still working even if the tank setpoint temperature is not reached.

@Gio, it does look like your connections are right. The heat recovery loop is working correctly and providing some heat from the chiller to the water heater, but there is still heat that must be rejected from the chiller to the condenser loop. That is why the condenser loop operates even when the tank setpt temp is not reached.

Currently, the 30C heat recovery water won't help the water heater achieve a typical >50C setpt temp. You may want to consider connecting the heat recovery loop to a storage tank without a heating element, then provide water from the storage tank to the water heater.

I'm sorry I didn't understand your last sentence. Do you mean with 2 different WaterHeater:Mixed? I think I would still need to connect the second one to another generator to integrate the remaining heat to reach 50°C

Correct, there would be two WaterHeater:Mixed objects: one with no heating capacity (max and min heating capacity set to zero) and source side nodes connected to the heat recovery loop, and a second with heating capacity and source side nodes connected to the first water heater. If the heating capacity of the second tank is large enough, it should be able to provide 50C water without another auxiliary heater or generator. Sorry for the confusion.

No confusion and thank you very much. I'm going to try it as soon as possible!
