What does R22 stand for?
R22 is the short name for the halocarbon compound CHClF2 (monochlorodifluoromethane), which is used as the refrigerant. R stands for the refrigerant. In the number “22” second “2” denotes the number of the fluorine atoms in the compound. The boiling point of R22 is -40.8 degree Celsius (-41.4 degree F).
Is R22 a liquid?
Properties of Refrigerant R22 Dichlorodifluoromethane – saturated liquid and saturated vapor – imperial and metric units. R22 can be used in small heat pump systems, but new systems can not be manufactured for use in the EU after 2003.
What is the specific gravity of R22?
1.197
The specific gravity for R-22 (at 77°F) is 1.197. Now the formula for the correct filling level of a 1,000-pound cylinder is 80 percent x 1,000 x 1.197 = 957.60 pounds.
What is the replacement for R22?
R-407c
The best replacement for R-22 Freon is usually R-407c. It has a very low loss in capacity (0 – 5%) relative to R-22 and is less expensive than many other R-22 replacement refrigerants. If a system has R22 in it already you cannot use a replacement refrigerant to simply add to the R22.
Is R22 an ODS?
What is R22 refrigerant? All refrigerated air conditioning systems use a substance known as refrigerant to effectively cool the interior of your business. R22 refrigerant, also known as HCFC-22, has been among the most common refrigerants used in previous years, but is a significant ODS.
Is R22 still available?
When the phase-out is complete in 2020, R22 refrigerant will no longer be available. The U.S. government has placed restrictions on R22 and has issued the requirement that R22 refrigerant must be eliminated from use in cooling systems by the year 2020.
What temp does R22 boil at?
-40.8 °C
Chlorodifluoromethane/Boiling point
How much R22 is in a 3 ton unit?
The amount of cooling for your system can be estimated in the range of 2 to 4 pounds per ton. The 3-ton AC or Heat Pump with a 35 foot lineset will need a total of about 12 pounds of refrigerant.
How do you calculate the density of air?
where P is the entered ambient pressure and P w is the water vapor pressure. The density of air calculation makes use of the ideal gas law: PV = nRT, where P, V and T is the pressure, volume and temperature respectively; n is the amount of substance, and R is the ideal gas constant.
What is the density of R-22 at 40°F?
They are the reciprocals of the density values.A good example is the liquid density of R-22 at 40°F. Column 4shows it to be 79.255 lb/ft 3.Divide 1 by 79.255 to get the reciprocal, 0.0126175.This is thespecific volume of liquid R-22 at 40°F. The same is true of saturated vaporat40°F. The density is 1.52 lb/ft3. The specific
How to calculate the saturation vapor pressure at dew point?
Combining these two values gives you the desired parameter. Calculate the saturation vapor pressure at dew point DP, using the formula p₁ = 6.1078 * 10^[7.5*DP /(DP + 237.3)]. Saturation vapor pressure means that the relative humidity is equal to 100%.
Which is the formula for the ideal gas law?
Note, that n ⁄ V is the density (ρ), then the ideal gas law can be re-written as follows: P = ρRT, and the formula for density is simply this: ρ = P ⁄ (RT). The pressure of wet air is the sum of the pressure of dry air (P d) and the water vapor pressure (P w ):
