System diagram
5.1 Cool only system circuit diagram
Evaporator Cross flow fan
Capillary Filter
Axial flow fan
Condenser
Gas liquid separator Compressor
When the power is on, indoor and outdoor units will start to run. The compressor sucks low-pressure refrigerant gas from the evaporator of 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

Gas liquid Separator Compressor
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, low-pressure 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, four-way valve changes its way and the refrigerant flows into the reversible cycle as the cool mode. The refrigerant discharges its latent heat in the indoor heat exchanger, and sucks heat from outdoor heat exchanger and forms the heat pump cycle. This cycle goes on and on, and the demanded high temperature environment is maintained.

Analysis or treatment of some of the display failures
1. Compressor discharge protection Possible causes: coolant not sufficient, air filter net is blocked, condenser is of poor ventilation or air flow is shorted, there is non-condensed gas in the system (such as air, water, etc.), capillary assembly (including filter) blockage, inner leakage in the 4-way valve, leading to mistaken action; compressor itself is with failure, failure is with protection relay itself, failure in exhaust temperature sensor and too high an outdoor temperature. Remedy: refer to the malfunction analysis in the above section.
2. Low voltage over current protection: Possible reason: Sudden drop of supply voltage.
3 Communication Malfunction:
Remedy: Check if communication signal cable is connected reliably
4 Open or short circuit with temperature sensor:
Remedy: Check whether sensor is normal, connected with the corresponding position on the controller and if damage of lead wire is found
5. Compressor over load protection: Possible reasons: shortage of refrigerant; blockage of capillary and increase of suction temperature; improper running of compressor, burning in or stuck of bearing, damage of discharge valve; malfunction of protector. Remedy: adjust the coolant amount, change capillary, replace the compressor, check the compressor with a multimeter and see if it conducts when it is not over heated, and replace the protector if it does not conduct.
6. System malfunction i.e. overload protection. When pipe temperature (Check the temperature of outdoor heat exchanger when cooling and check the temperature of indoor heat exchanger when heating) is too high, protection will be activated. Possible causes: too high an outdoor temperature when cooling, air ventilation outdoor is not sufficient or failure in coolant flow. Remedy: refer to the malfunction analysis in the above section.
7. The cooling pressure is about 0.9Mpa and the heating pressure is about 3.0 Mpa when the frequency
converter split system is operating normally. If the pressure is lower than the normal range, there is possibly leakage. If it is higher than the normal range, it is possibly due to too much coolant or air mixing in the system. The pressure also depends on various conditions.
8. IPM module protection(H5):
Remedy:
Check if the voltage between power module P and N is too low (when input voltage is lower than 178V, the compressor will stop); if the current is too high (when the input D.C. is higher than 46A, the compressor will stop). In normal condition, voltage between P and N should be 310V
Normal
Abnormal
Check the power circuit of outdoor unit(PTC resistor, rectifier bridge, reactor aNd capacitor for failure).
Temperature of power module is too high,
which causes overheating protection
Check if radiating paste is spread evenly or radiating sticker is stuck well; if screws of power module is tightened
Reinstall power module and re-spread radiating paste or stick radiating sticker on the radiator of power module.
Still indicating protection
Confirm the setting status of outdoor unit (cooling)
Poor radiation, heat exchanger is dirty
Remove obstructions and clean
