[Virtual-sim] R: High heating loads in VRF system

[Francesco Passerini]

Hello, have you tried to plot the COP values of the VRV system, in order to evaluate whether those values are realistic?

Oggetto: [Virtual-sim] High heating loads in VRF system

  Hello All -

I am modeling a VRF system for a office/safety center in North Carolina. I am seeing a very high heating energy consumption, higher than the baseline system. Considering this building is in NC, does not fit right.

I used the default curves within IES VE and also tried the Mitsubishi curves. The 2019 IESVE diakin plugin is not working and hence I am able to only try with the above two curves.

See graph below compared to my baseline heating energy.

Has anyone else seen this in their models?
