What kind of oil is used in R22?

mineral oil
Refrigerant R-22 has been successfully used with mineral oil in residential air-conditioning and heat pump systems (AC/HP). R-407C and R-41 OA are two chlorine free HFC refrigerant candidates to replace R-22.

What oil is used with R507?

Polyol Ester synthetic oil
The use of Polyol Ester synthetic oil is the rule in R507 refrigeration systems. This oil has superior lubricating ability over the mineral oils commonly used in older CFC refrigerant systems. 1. Only POE oil should be used in a R507 system.

What type of oil is used to lubricate R290 refrigeration systems?

As the lubricating oil, mineral oil (MO) has been most applicable for R22; synthetic oils (POE and PAG) are suit for R410A. These oils also have good miscibility with R290.

Is R507 toxic?

INHALATION: R-507 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. At high levels, cardiac arrhythmia may occur.

Is R507 a blend?

R507 is a HFC blend, used as a replacement for R502 and R22 in low and medium temperature refrigeration. With a Global Warming Potential (GWP) of 3985, R507 is under similar scrutiny to R404A.

How much oil is in a refrigeration system?

The AC system requires a Usually of 4 ounces (120 ml) of oil in most modern automobiles.

Can R22 make you sick?

Breathing air that is contaminated with Freon can cause respiratory difficulties, organ damage and, in some cases, death. Symptoms can vary depending on the extent of the Freon exposure, but even a small amount of exposure can cause serious symptoms in humans.

Is R22 harmful to breathe?

INHALATION: R-22 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. At high levels, cardiac arrhythmia may occur.

What are normal R22 operating pressures?

R22 gauge pressure is 10.9 bar or 158.2 psi. High side pressure typically varies by equipment and metering controls. Low pressure or suction side typically varies by equipment. Low-pressure refrigerant turns on the carrier HVACR at 50 psi (R22 pressure at 30 degrees) and closes at 100 psi (R22 pressure at 85 degrees).
