so that when the outdoor conditions cause a non-zero defrost power, AND the
system if off, defrost power would be set to zero.

Pdischarge is the compressor discharge pressure,
this->CompMaxDeltaP is the maximum compressor pressure rise
Pdischarge - this->CompMaxDeltaP is minimum compressor suction pressure

RefMinPe is minimum refrigerant evaporating pressure

These two terms are both lower bounds of the suction pressure

CapMinPe should be no less than both of them, so CapMinPe should be max of the
two LB, not min

the error message counter is a sum of all previous counter values
it overflows to negative
non-recurring warning keeps showing up after the overflow
use the counter, not the sum of counter in the predicate

because the demand is roughly Q_evap_req = TU_load + Pipe_Q - Ncomp (multiplied
by an adjustment factor C_cap_operation). Ncomp is an input-ouptut variable of
the function. Previously Cycling ratio is multiplied outside of VRFOU_CalcCompH
after the function has computed Ncomp. However, this will lead to very small
cycling ratio non-compatible with the demand as the demand is underestimated
because of the Ncomp (in reality it should not be this large, it should be
Ncomp * CyclingRatio). This doesn't matter on the cooling side as Ncomp is not
involved in the demand calculation there.
