LGETH -180704-054 / Rev. 0LG Electronics
Refrigerant Charge Limit Max 2,500g
(Charge limit depends on Oil Dilution Rate**note 2 & accumulator ‘K’)
Liquid Refrigerant Back
System should be designed not to allow the liquid to go back to
compressor which cause knocking noise , current increase or
undesirable vibration and make short compressor life time.
Δ T : Temp. Difference Δ T = Case Bottom Temp.－ Condensing Temp.
It must be kept Δ T ≥ 5℃
Pressure Difference
in Operating
The Pressure difference in operating shall be 5.0㎏f/㎠ or more,
but 3 minutes starting excluded.
ON/OFF Operation Each cycle should be at least 6 minutes
(ON Time : at least 3 minute , OFF Time : at least 3 minutes)
3.2 Application Limit
※This guide contains many important safety messages. Always read and obey all safety messages.
You can be killed or seriously injured if you don’t follow instructions.
Page 9 / 24GVH2 2PAB
(ON Time : at least 3 minute , OFF Time : at least 3 minutes)
Pressure Difference
at Starting
When starting, discharge pressure is balanced with suction pressure.
( Pd – Ps ≤ 0.5 ㎏f/㎠ )
Tilt in Operation The allowable tilt of the compressor in operation shall be 5˚ or less.
System Accumulator
The Accumulator volume should be enough to cover 50% of
maximum system refrigerant volume.
Ratio coefficient ‘K’ should be over 0.6(heating system) or 0.4(cooling
system)
Effective Volume of Accum. × Specific gravity of Refrigerant
K = --------------------------------------------------------------------------
Charged Weight of Refrigerant
※ Effective Volume of Accumulator = 580 ㎤
※ Specific Gravity of Refrigerant (R410A) = 1.085 g/㎤ ( at 20℃ )
If coefficient “K” does not meet recommendation, refrigerant system
must check liquid back phenomenon at accumulator.
Protecting Reverse
Operation
The compressor must be operated by proper voltage in accordance
with the frequency without reverse revolution condition. The reverse
revolution condition can be avoided by just keeping right order of
phase supplied power source.
LGETH -180704-054 / Rev. 0LG Electronics
Frequency Range Rated Frequency ±2%
Pipe Stress Don’t allow any force on discharge & suction pipe .
The piping stress must be less than 300㎏f/㎠at starting and stopping.
And less than 153㎏f/㎠at running.
Oil Level It must be checked oil level by the compressor with
sight glass we supply. And oil level must be kept over
guide line level **note 3. at any condition.
Protection device Refrigeration system must has the compressor protection device like
over pressure, high temperature, sensing locked pump in the controller.
When starting & running fail by abnormal overload, controller must be
able to cut off power of compressor before motor burn out.
An earth terminal should be installed to prevent electrical accidents.
3.2 Application Limit
Page 10 / 24GVH2 2PAB
Pump down
refrigerant
If pump down time is too long, compressor can be damaged due to
excessive temperature increase or poor lubrication.
Guideline of pump down process.
- Time : less than 30 seconds
- Suction Pressure : It should not run under below 1㎏f/㎠G.
And before closing a service valve, compressor running for more than 5
minutes is recommended.
※If gas charge amount of refrigerant specified is exceeded,
both parties should discuss the matter to determine compressor specification.
(accumulator volume, lubricating oil amount) and system specifications (crank case
heater, oil separator , additional accumulator, etc)
