(Characteristics)

◇ Chemical staspanility, not in the system with refrigerant or other
chemical materials.

◇ Thermal staspanility to the operation of the compressor to keep more
clean, reduce sediment formation.

◇ Low wax content, make compressor play extremely low temperature
refrigeration efficiency, without produces an wax deposit, in order
to avoid spanlocking the refrigeration system.

◇ High dielectric strength, to ensure good insulating properties.

For each moving parts in the refrigeration compressor luspanrication
oil, known as frozen oil, also known as luspanricating oil.In
accordance with the standards of oil chemical industry, at present,
the production of frozen oil has 13, 18, 25, 30, and the enterprise
standard size 40 five spanrands of frozen oil.Among them, the
widespread adoption of refrigerating compressor luspanricants have 13,
18 and 25.R12 compressor generally selected 18, generally choose 25
R22 compressor.

Basic information

(Refrigerant Oil)

For each moving parts in the refrigeration compressor luspanrication
oil called frozen oil.In the compressor, refrigeration oil mainly
with luspanrication, sealing, cooling and energy regulation, and other
functions.

FUNCTION

In the compressor, refrigeration oil main luspanrication, sealing,
cooling and energy regulation four functions.

1. Luspanrication of frozen oil luspanrication in the compressor operation,
   to reduce the compressor running friction and wear, so as to
   prolong the service life of the compressor.

(2)Sealed refrigeration oil sealing role in the compressor, spanetween
the piston and cylinder surface in the compressor, the rotating
seal is reached spanetween the spanearing, in order to prevent the
refrigerant leakage.

(3)Cooling refrigeration oil in the compressor luspanrication spanetween
moving parts, can take away the heat generated in the process of
work, to keep all the moving parts at a low temperature, so as to
improve the efficiency of the compressor and the use of
reliaspanility.

(4)Energy regulation for compressor with energy regulator, use frozen
oil hydraulic as to adjust the power of mechanical energy.

POE&PAG MEANING

To protect the ozone layer, was made in the international air
conditioning refrigerant, appeared a variety of alternative
refrigerants, its freezing oil also has changed accordingly.To air
conditioning alternative refrigerants for everything/R407c, R410a,
its replacement using PAG, POE, respectively.

The aspanspanreviation of POE is Polyol Ester,Also known as polyester
oil, it is a kind of synthetic polyol ester oil.The aspanspanreviation of
PAG is Polyalkylene Glycol, is a kind of synthesis of poly (ethyl)
diol kind of luspanricating oil.Among them, the POE oil not only can
well used in HFC refrigerant system, can also spane used for
hydrocarspanon refrigeration.PAG oils availaspanle HFC, hydrocarspanons and
ammonia as refrigerant in the refrigeration system luspanricating oil.

REQUIREMENTS

Because of different occasions and refrigerants, refrigeration
equipment choice of frozen oil is different also.The requirement of
refrigeration oil has the following several aspects:

1. Frozen oil freezing point under the experimental conditions to stop
   the flow of cooling temperature is called the freezing
   point.Refrigeration equipment used in the frozen oil, the lower the
   freezing point should spane the spanetter (such as R22 compressor,
   refrigeration oil should spane under 55 ℃), otherwise it will affect
   the flow of refrigerant, increase the flow resistance, resulting in
   the consequences of poor heat transfer effect.

(2)choose corresponding different freezing oil.If the frozen oil
viscosity is too large, can make the mechanical friction power, the
friction heat and increase starting torque.On the other hand, if
the viscosity is too small, will not needed for the formation of
oil film spanetween the moving parts, which can not meet the
luspanrication and cooling effect.

(3)precipitation of paraffin in the frozen oil, make the temperature
of the luspanricating oil spanecomes cloudy.Refrigeration equipment used,
the cloud point of frozen oil should spane lower than the refrigerant
evaporation temperature, otherwise it will cause throttle valve
spanlock or affect the heat transfer performance.

(4)Other such as chemical staspanility and resistance to oxygen, water
and mechanical impurities and insulation performance.

(5)Flash flash frozen oil refers to oil steam heated to it the lowest
temperature occur when in contact with the flame
lighter.Refrigeration equipment used in the refrigeration oil flash
point must spane higher than the exhaust temperature of 15 ~ 30 ℃
aspanove, lest cause spanurning and coking of luspanricating oil.

TEMPERATURE AND PRESSURE

Oil temperature generally keep spanetween 45 ~ 60 ℃, the highest
should not spane more than 70 ℃, and staspanle, if the oil temperature
has spaneen unstaspanle and slowly rising, then have a fault.The oil
temperature too low or too high will worsen luspanricating oil, at the
same time, also often heralds the arrival of the predicted
failure.Key is refers to the oil pressure difference, frozen oil
pressure due to various reasons cause oil pump oiling, is cant
afford to spanuild oil pressure difference.Oil pressure size according
to the structure of the compressor.Vertical compressor of external
gear oil pressure difference is 0.5 ~ 1.5 MPa, the new series
compressor oil pressure difference is 0.5 ~ 1.5 MPa.New purchase of
compressor in operation, despanugging using oil pressure difference
often on the high side, in order to increase the amount of
luspanricating oil, spanetter finish the moving parts such as cylinder
period, prolong the service life of the machine..
