R-11 production was phased out in 1995 but reclaimed R-11 is still available. Older R-11 chillers can continue to be serviced with available R-11 or be retrofitted to R-123 with engineering support from the equipment manufacturer.
What is a characteristic of R 12 refrigerant?
1) Safe properties: Refrigerant R12 is nontoxic, nonflammable, and non-explosive. This makes it highly popular for the domestic as well as the commercial applications. 2) Stability: R12 is highly stable chlorofluorocarbon and it does not disintegrate even under the extreme operating conditions.
What is R11?
Refrigerant R-11 is another refrigerant used commonly in the refrigeration and air conditioning systems. The chemical name of R11 is trichloromonofluoromethane (it is methane series compound) and its chemical formula is CCl3F. R-11 refrigerant is also used as the solvent and the secondary refrigerant.
Is R 11 an HCFC?
CFC Refrigerant: CFC refers to the chemical composition of the refrigerant. Chlorofluorocarbon indicates that the refrigerant is comprised of Chlorine, Fluorine, and Carbon. Common CFC refrigerants are R-11, R-12, R-13, R-113, R-114, and R-115. Common HCFC refrigerants are R-22, R-123, R-124, and R-142b.
What is the shape of Freon 12?
Is R-12 toxic?
Dichlorodifluoromethane (alias of R 12 (refrigerant)) A) Freons are very toxic when inhaled in high concentrations and/or for extended periods. At lower concentrations or brief exposure, freons may cause transient eye, nose, and throat irritation.
What is the difference between R11 and r13?
The r11 is 23c/sq. ft, the r13 is 33c. So a diff.
What are the properties of a good refrigerant?

What should the freezing point of refrigerants be?
Refrigerants should have low freezing point than the normal operating conditions. It should not freeze during application. Water for example cannot be used below 0 Deg C.
How are refrigerants used in the heating cycle?
Refrigerants are widely used in Refrigeration cycle where cooling effect below the atmospheric temperatures are needed. Whenever we choose them for particular use Properties of Refrigerants also plays a vital role in economic and environmental friendly application. Here are some of the desirable properties of refrigerant explained in detail.
