5.4.4 Electronic Expansion Valve (EXV)
For M5OG-48HFN1-M-[X],
1. After the outdoor unit is powered on again,
the EXV is first closed -520P, and then in
standby mode (if the current mode is heating
mode, the initial heating degree is run,
otherwise the initial cooling degree is run, and
the internal machine is not connected. deal
with 7k unit). The main valve first opens 510P,
then opens 530P, and then is in the standby
state (if the current outdoor mode is the
heating mode or the standby mode, it
maintains 0P, and the cooling mode opens to
the initial cooling opening). The EVI valve
opens 510P first, then 530P, then the counter
is cleared to 0P.
2. After the compressor is stopped,
2.1 If the EVI valve has a valve opening action
before the stop, the PMV_CLOSE_EE step is
closed in the reverse direction after the stop, and
then the EXV opening counter is cleared to 0P. If
the EVI valve does not operate before the stop,
0P will be maintained.
2.2 Reverse the valve to close the
PMV_CLOSE_EE step (after closing the valve to
the 0P, and then continue to run
PMV_CLOSE_EE in the valve closing direction,
the EXV opening counter is cleared. If the current
opening is 300P, go to the valve Run the 320P in
the closing direction to close the EXV.), then in
the standby state (if the current outdoor mode is
the heating mode, the initial heating opening is
run, otherwise the initial cooling opening is run,
and the internal machine is not connected. deal
with 7k unit).
2.3 Main EXV action: When the compressor is off,
the main EXV keeps the opening degree when
the compressor is turned off within the first 90
seconds. If it is currently heating mode, -20P,
clear and keep 0P, otherwise adjust to 480P.
3. Other EXV(except for EVI valve) cannot be
operated at the same time. The action priority
order is A-B-C-D-E-main valve. The EVI valve
can be operated together with other EXV.
For other models,
Control
1. EXV remains fully closed while the device is
powering up. EXV then remains on standby with
350P open. It opens to the target angle after the
compressor starts.
2. EXV closes with -40P when the compressor
stops. Then it remains on standby with 350P
open. It opens to the target angle after the
compressor starts.
3. The action priority for the EXVs is A-B-C-D-E.
4. The compressor and outdoor fan commence
operation only after EXV initializes.
5.4.4.1 Cooling Mode
The initial open angle of the EXV depends on the
size of the indoor model. The adjustment range is
100-400p.
When the unit has been running for 3 minutes,
the outdoor receives indoor units' capacity
demand and T2B information and then calculates
their average. After comparing each indoor’s T2B
with the average, the outdoor gives the following
modification commands:
---- If the T2Baverage, the relevant valve needs
to open 16p more
---- If the T2B= average, the relevant valve’s open
range remains as is
---- If the T2Baverage, the relevant valve needs
to close 16p more
This modification is carried out every 2 minutes.
