[Equest-users] TFA with ERV

[sambhav tiwari]

Hi All ,


My  project was having VRV units with OA(TFA) system .So i created a
OA system (100% OA) and assigned  all  indoor system as OA from this
system but when i am adding ERV to this OA system my cooling energy is
go drastically up almost doubled . but all my indoor VRV units are
getting OA from
this system. Than why  putting ERV to this system increases cooling energy?
Thanks
