Do POE and PAG oils absorb moisture?
PAG oil: Polyalkylene Glycol or PAG oil is a man-made lubricant used in both R134a systems and the latest R1234yf. And because it does not absorb moisture, it is also used to lubricate O-rings and seals in both R-12 and R134a systems.
Does R-410A use POE oil?
Polyolester oil (POE oil) is a type of synthetic oil used in refrigeration compressors that is compatible with the refrigerants R-134a, R-410A and R-12.
Can you remove moisture from POE oil?
Moisture will stay dissolved in the oil and cannot be readily removed by applying a vacuum; moisture can only be removed from POE oil with the use of a desiccant. Again, normal servicing practices always recommend replacing the liquid line filter-drier when a system is opened for service.
Does R-410A absorb moisture?
The lubricants used with most R-410A systems will absorb so much moisture that if you fill a glass half-full with POE oil and come back an hour later, the glass will be half full of water.
Can you mix POE oil and PAG oil?
PAG oil and POE oil do not mix properly. A high percentage of POE will reduce lubrication performance.
What is the difference between PAG oil and POE oil?
Polyolester (POE) – the primarily synthetic oil for refrigeration systems using HFC refrigerants. Polyalkylene Glycol (PAG) – a synthetic oil primarily used in R-134a automotive air conditioning systems. It is more hygroscopic that either POE or PVE oils, but it does not undergo hydrolysis in the presence of water.
What happens when refrigerant and moisture mix?
Water can interact with: Refrigerants, forming clathrate hydrates. One possible cause of copper plating is moisture reacting with refrigerant to form an acidic solution. The acids then dissolve or leach copper from components in the A/C system that are copper or contain copper-based alloys, such as brass or bronze.
Does refrigerant absorb moisture?
It removes the warmth AND the moisture from the indoor air. After the refrigerant absorbs the moisture and warmth from the indoor air, excess condensation drains out of your unit through the condensate pan underneath the evaporator coil. So, to answer your question; Yes, your air conditioner does remove humidity!
How bad is 410A refrigerant?
The most common refrigerants, R-410a (Puron) and R-22 (Freon), are neither toxic nor flammable – but they are heavy enough to fill a room and push out the oxygen until you suffocate. Health symptoms and HVAC unit signs can indicate a leak and you should call a professional if you suspect one in your home.
Is it bad to breathe in R-410A?
Mist may irritate. INHALATION: R-410A is low in acute toxicity in animals. When oxygen levels in air are reduced to 12-14% by displacement, symptoms of asphyxiation, loss of coordination, increased pulse rate and deeper respiration will occur. Some effects of inhalation and skin exposure would be expected.
Which refrigeration oils can be mixed?
When using CFC or HCHC refrigerants, POE and MO can be mixed. The exception is R12 that only uses MO or Alkyl Benzene Mineral Oil (ABMO) blend. HFC refrigerants can only use POE oil.
Can you mix PAG and POE oil?
