PIPING DIAGRAM
Schematic Diagram of High Power Multi System
The units start to work once the power is switched on.
During the cooling operation, the low temperature, low pressure refrigerant gas from the heat exchanger of
each indoor unit gets together and then is taken into the compressor to be compressed into high temperature, high
pressure gas, which will soon go to the heat exchanger of the outdoor unit to exchange heat with the outdoor air
and then is turned into refrigerant liquid. After passing through the DB module, the temperature and pressure of
the refrigerant liquid will further decrease and then go the main valve. After that, it will be divided and go to the
heat exchanger of each indoor unit to exchange heat with the air which needs to be conditioned. Consequently, the
refrigerant liquid become low temperature, low pressure refrigerant gas again. Such a refrigeration cycle goes
round and round to achieve the desired refrigeration purpose.
During the heating operation, the four-way valve is involved to make the refrigeration cycle run reversely.
The refrigerant radiates heat in the heat exchanger of the indoor unit (so do the electric heating devices) and
absorb heat in the heat exchanger of the outdoor unit for a heat pump heating cycle so as to achieve the desired
heating purpose.

2MAIN LOGIC
2.1 Control Function of Outdoor Unit
2.1.1 Cooling Mode
1) Cooling conditions and process:
If the compressor is in stop status and start the unit for cooling operation, when one of the indoor units
reaches the cooling operation condition, the unit starts cooling operation; in this case, the electronic expansion
valve, the outdoor fan and the compressor start operation.
2) Stop in cooling operation
a) Compressor stops
The compressor stops gradually, the outdoor fan stops after 1 min.
b) Some of the indoor units reach the stop condition (the compressor does not stop)
The compressor operates according to the required frequency. For the indoor unit with no requirement, the
corresponding electronic expansion valve is closed to 0P.
3) Cooling mode transfers to heating mode
When the unit transfers to heating mode, the 4-way valve is energized after the compressor runs for 40s. The
other disposals are the same as stopping in cooling mode.
4) 4-way valve:
In this mode, the 4-way valve is closed.
5) Outdoor fan control in cooling mode
The outdoor fan starts before 5s of the starting of compressor. The outdoor fan will run in high speed for 40s
after starting and then it will run in set speed.
The fan shall run at every speed for at least 80s. (When the quantity of indoor unit changes, the control part
will adjust the outdoor fan according to the quantity of indoor unit and outdoor temperature.); when the
compressor stops, the outdoor fan runs at present speed and stops after 1 min.
2.1.2 Dry Mode
1) The dry conditions and process are the same as those in cooling mode;
2) The status of 4-way valve: closed;
3) The temperature setting range: 16 ~ 30℃;
4) Protection function: the same as those in cooling mode;
5) In dry mode, the maximum value A of the capacity requirement percentage of single unit is 90% of that
in cooling mode. The open condition of the electronic expansion valve, outdoor fan and compressor is
the same as those in cooling mode.
2.1.3 Heating Mode
1) Heating conditions and process: When one of the indoor units reaches the heating operation condition,
the unit starts heating operation.
2) Stop in heating operation:
a) When all the indoor units reach the stop condition, the compressor stops and the outdoor fan stops after 1
min;
b) Some of the indoor units reach the stop condition. The compressor reduces the frequency immediately and
operates according to the required frequency;
c) Heating mode transfers to cooling mode (dry mode), fan mode:
The compressor stops;
The outdoor fan stops after 1min;
9
The status of 4-way valve: energized;
3) Outdoor fan control in heating mode
The outdoor fan starts before 5s of the starting of compressor and then it will run in high speed for 40s; The
fan shall run at every speed for at least 80s; When the compressor stops, the outdoor fan stops after 1min.
4) Defrosting function
When the defrosting condition is met, the frequency of the compressor starts to decrease and wait for
defrosting; the electronic expansion valve of all indoor units open in big angle; the outdoor fan stops after the stop
of the 4-way valve, meanwhile, the 4-way valve reverses the direction; after the 4-way valve reverses the direction,
the frequency of the compressor starts to rise; then begin to calculate the time of defrosting, the frequency of the
compressor rises to reach the defrosting frequency.
5) Oil-returned control in heating mode
a) Oil-returned condition
The whole unit is operating in low frequency for a long time
b) Oil-returned process in heating mode
The indoor unit displays “H1”.
c) Oil-returned finished condition in heating mode
The duration reaches 5min
2.1.4 Fan Mode
The compressor, the outdoor fan and the 4-way valve are closed; temperature setting range is 16～30℃.
2.2 Protection Function
2.2.1 Mode Conflict Protection of indoor unit
When the setting mode is different of different indoor unit, the unit runs in below status:
1) The mode of the first operating indoor unit is the basic mode, when compare the mode of the other
indoor units to see if there is a conflict. Cooling mode (dry mode) is in conflict with heating mode.
2) Fan mode is in conflict with heating mode and the heating mode is the basic mode. No matter which
indoor unit operates first, the unit will run in heating mode.
2.2.2 Overload Protection Function
When the tube temperature is a little low, the compressor raises the operation frequency; when the tube
temperature is a little high, the compressor frequency is restricted or lows down the operation frequency; when the
tube temperature is too high, the compressor protection stops running. If the discharge temperature protection
continuously appears for 6 times, the compressor can’t resume running. The compressor can resume running after
cutting off the power and then putting through the power. (If the running time of the compressor is longer than
7min, the protection times record will be cleared).
2.2.3 Discharge Protection Function
When the discharge temperature is a little low, the compressor raises the operation frequency; when the
discharge temperature is a little high, the compressor frequency is restricted or lows down the operation frequency;
when the discharge temperature is too high, the compressor protection stops running. If the discharge temperature
protection continuously appears for 6 times, the compressor can’t resume running. The compressor can resume
running after cutting off the power and then putting through the power. (If the running time of the compressor is
longer than 7min, the protection times record will be cleared).
10
2.2.4 Communication malfunction
Detection of the quantity of installed indoor units and DB modules: After 3min of energizing, if the outdoor
unit does not receive the communication data of certain indoor unit, the outdoor unit will judge that indoor unit is
not installed and will treat it as it is not installed. If the outdoor unit receives the communication data of that
indoor unit later, the outdoor unit will treat that unit as it is installed.
2.2.5 Compressor high-pressure protection
1) When the high-pressure switch is detected cut off for 3s continuously, the compressor will enter
high-pressure protection as it stops when reaching set temperature. Meanwhile, the outdoor unit will
send the signal of “high-pressure protection” to the indoor units;
2) After the appearance of high-pressure protection, the compressor can resume running only after cutting
off the power and then putting through the power.
2.2.6 Compressor low-pressure protection
1) Low Pressure Protection for Shutdown
a). After the compressor stops for five minutes, if it is detected that the low pressure protection is work, then
a low pressure protection signal will be send out.
b). If it is detected continuously for three seconds that the low pressure protection is work after the
compressor stops for less than five minutes, then a low pressure protection signal will be send out. However, if the
low pressure protection occurs twice in one hour, then it becomes unrecoverable and has to be recovered by
powering the outdoor unit again.
2) Low Pressure Protection during the Operation
a) When it is detected continuously for three seconds that the low pressure protection is work, then the whole
unit should be shut off and a low pressure protection signal should be sent to the indoor unit.
b) On condition that a low pressure protection error occurs and the whole unit has stopped for more than
three minutes and it is detected continuously for six seconds that the low pressure protection switch is closed, then
this error can be eliminated. However, if the low pressure protection occurs twice in one hour, then it has to
eliminate the error by powering the outdoor unit again.
2.2.7 Compressor overload protection
If the compressor overload switch is detected having movement, the indoor unit will display the
corresponding malfunction as it stops when the indoor temperature reaching set temperature. When the
compressor stops for more than 3min and the compressor overload switch is reset, the unit will resume operation
status automatically. If the protection appears for more than 6 times (if the running time of the compressor is
longer than 30min, the protection times record will be cleared), the unit can not resume operation status
automatically, but can resume running only after cutting off the power and then putting through the power.
2.3 Other function
2.3.1 Refrigerant Recovery
