Compressor

When the power is on, indoor and outdoor units will start to run. The compressor sucks low-pressure refrigerant gas from the evaporator
indoor unit and then discharges high-temperature, high-pressure refrigerant gas into outdoor condenser. Then air exchanges the heat with outdoor air
and becomes refrigerant liquid. The liquid is throttled by the capillary and changes into low-temperature and low-pressure liquid and then flows

into indoor evaporator. Then liquid exchanges the heat with the required air and changes into low-temperature and low-pressure refrigerant gas.

The cycle introduced above goes on and on, and the demanded low temperature environment is maintained.

Heating

Cooling

When the power is on, indoor and outdoor units will start to run. When the system operates in cool mode, the compressor sucks low-temperature, low­pressure refrigerant gas from indoor evaporator and then discharges high-temperature, high-pressure refrigerant gas into outdoor heat exchanger. With
the help of axial flow fan, the gas transfers its latent heat into outdoor air and becomes high-pressure refrigerant liquid. The liquid is throttled by the
capillary and changes into low-temperature and low-pressure liquid and then flows into indoor heat exchanger. With the help of centrifugal fan, the

liquid evaporates into low-temperature refrigerant gas and indoor air is cooled down. The refrigerant gas is sucked into the compressor and the cycle

introduced above goes on and on, and the demanded low temperature environment is maintained.
When the system operates in heat mode, 4-way valve changes its way and the refrigerant flows into the reversible cycle as the cool mode. The

r

e frigerant discharges its latent heat in the indoor heat exchanger, and sucks heat from outdoor heat exchanger and forms the heat pump cycle.

T his cycle goes on and on, and the demanded high temperature environment is maintained.

Foundamental functions

After power is on, no matter when compressor is started, the time span between the startups cannot be less than 3 minutes.

COOL mode

Cooling condition

If Tamb≥Tset+1℃, COOL mode will act, compressor and outdoor fan will run, indoor fan will run at the set speed.

If Tamb≤Tset－１℃，tunit will stop , compressor will stop and then outdoor fan will delay 15sec and stop.

If Tset-1℃＜Tamb＜Tset+1℃, the unit will keep running in the old mode.



In this mode, the reversal valve will not power on, the setting temp. range:16℃~30℃

Protection Functions



Overcurrent Portection

When the system current is tested higher than 13A, only fan will run. After 3 minutes, the whole unit will run in the old

mode, if the overcurrent cannot be eliminated, the whole unit will stop, and can be restarted by the wireless remote control.

Antifreezing Protection



When the system is tested, the compressor and outdoor fan will stop, indoor fan will run at the set speed; when the antifreezing protection is
and the compressor has stopped for 3min, the unit will return to the old mode.

If Tset -2℃≤Troom≤Ｔset+2℃，DRY mode will act, the indoor fan will run at the low speed.after running for 6mins, outdoor fan and compressor will stop, but

indoor fan will delay 30secs and stop, after 3.5mins, compressor and outdoor fan will run, and indoor fan will run at the low low speed. The processes of dehumidifying

In this mode, the reversal valve will not power on, the setting temp. range:16℃~30℃.

Protection Functions



Antifreezing Protection

When running in COOL mode, antifreezing protection is the same as the cooling. The DRY mode act, when the antifreezing protection is detected,
the compressor will stop, but outdoor fan will delay 15secs and stop, indoor fan will run at low speed; when antifreezing protection is eliminated and
compressor has stopped for 3min, the whole unit will run at the original status.

HEAT Mode

The conditions and processes of heating

If Tamb　≤Tset+2℃, HEAT mode will act, compressor, outdoor fan and reversing valve will run, but indoor fan will after 20sec delayed and run.

If Tamb≥Tset+4℃, Compressor will stop first, outdoor fan will delay 15s and stop, reversing valve will keep working, after 30secs indoor fan will blow
the surplus heat, after 30secs it will stop.

If Tset+2℃＜T set＜T set +4℃,the unit will keep running in the old mode.

In this mode, the reversal valve will not power on, the setting temp. range:16℃~30℃.
