Can heat recovery chiller be modeled in cbecc-com 2019 or energy pro? this chiller doesn't have a typical heat rejection system or connected to a cooling tower. The HRC uses coils (heating coils and cooling coils) in the exhaust air of each air handler to either generate cold water or hot water by either heating or cooling the air to certain temperate. we are looking to document the TDV saving compared to T-24-2019 in a reasonable manner. Looking at energy pro v8 it looks like there is no way to represent this system. Any suggestions or pointers would greatly help.

Thanks, Aditya

No, CBECC-Com 2019 does not support heat recovery chillers. One way to do this would be to model it as a regular chiller in CBECC-Com, then modify the IDF produced by CBECC-Com and substitute in the relevant EnergyPlus objects to convert it to a heat recovery chiller. You can always apply the TDV factors directly in EnergyPlus or post-process it in a spreadsheet.

Thank you, Eric, for the suggestion/guidance. I previously attempted to use central heat pump object (to represent HRC) within open studio/energy plus. However, I wasn't successful in getting it to run. I give it another try.
