3. Vent cfc of hcfc since

July 1, 1992

Nov 14, 1994

July 6, 1991

Nov 15, 1993

The correct answer is July 1, 1992. This date marks the implementation of regulations to limit the emission of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). These substances are known to deplete the ozone layer and contribute to global warming. By setting a maximum limit on the release of CFCs and HCFCs, the international community aimed to protect the ozone layer and mitigate climate change.

8. What yeat was the sale of CFC anf HCFC refrigerants restricted to certified technitions

March 5, 1994

July 15, 1995

Nov 14, 1994

Jan 6, 1996

The correct answer is Nov 14, 1994. This is the date when the sale of CFC and HCFC refrigerants was restricted to certified technicians. It means that after this date, only technicians who were certified and trained in handling these refrigerants were allowed to purchase and use them. This restriction was put in place to prevent the release of harmful substances into the environment and to ensure that proper handling and disposal practices were followed.

This restriction was put in place to prevent the release of harmful substances into the environment and to ensure that proper handling and disposal practices were followed.

9. The synthetic lubricant used with HCFC based ternary blends is

Alkyl-benzene

Mineral

PAG

Ester

The correct answer is alkyl-benzene because it is a commonly used synthetic lubricant that is compatible with HCFC (hydrochlorofluorocarbon) based ternary blends. Alkyl-benzene lubricants have good thermal stability, chemical resistance, and lubricating properties, making them suitable for use in various applications. They also have low solubility in refrigerants, which helps prevent oil carryover and maintain system performance. Additionally, alkyl-benzene lubricants are environmentally friendly and have a low impact on ozone depletion and global warming potential.
