Zero value for QBCOMP variable

[aymhenry]

First

In class QCtrl_Ql8, method calculte_cycle
used to make cycle calculation, for configuration 2, mode 8

Variable (self.obj_data.QBCOMP) always zero.

I need to put

self.obj_data.QBCOMP = 0

somewhere before line 635, or an error will be raised.

Second
In file Ql5, the same problem

224		Cab.QBCOMP = 0.0
225		Cab.QFRZ = QTNOBOT  +  Cab.QBOTTM  +  Cab.QBCOMP

it is useless statement, better to remove (self.obj_data.QBCOMP ) from both equation.
confirmation required.

Ayman, I prefer to keep them for conformity. QBCOMP is the heat flux from the compressor bottom compartment. I don't know what is QL5 and QL8 if these are configurations where the compressor compartment doesn't interact with the freezer - then you can safely remove it.

Good, I will keep this and others if any.

files Qlxxx like Ql13, Ql2, Ql467, Ql5 and Ql8.
Ql3 related to mode 3
Ql8 related to mode 8 etc.

Configuration 1 i.e mode 3 uses Ql13.py
Configuration 2 i.e mode 8 uses Ql8.py
Configuration 3 i.e mode 2 uses Ql2.py
Configuration 5 i.e mode 5 uses Ql5.py
Configuration 6 i.e mode 4 uses Ql467.py
Configuration 7 i.e mode 3 uses Ql3.py

for compressor compartment
It is considered in Qlxxx files by variable NCCTYPE.

NCCTYPE variable is calculated in QCtrl line 95-113
