Unit 26 HW Review Questions

What is the significance of the Montreal Protocol?

• The Montreal Protocol IS AN International agreement that established target dates for the phase out of ozone depleting substances.

• A is probably the best answer

What is the possible fine for violating the Clean Air Act?

• $97,229 per incident per day.

• Life in prison.

List the major provisions of Title VI, section 608 of the 1990 clean air act.

• A prohibition on venting ozone depleting refrigerants Technician certification

  Restrictions on the sale of ozone depleting refrigerants Reclaimed refrigerant standards

  Certification of recycling and recovery equipment Refrigerant recovery levels

  Repair of substantial leaks in equipment with a charge greater than 50 pounds. Safe disposal of appliances containing ozone-depleting refrigerant

  Record keeping for technicians, employers, wholesalers, and equipment owners

• EPA Stuff is fun.

List the exceptions to the ban on venting ozone depleting refrigerant.

• “De minimis” quantities of refrigerant released in the course of making good faith attempts to recapture and recycle or safely dispose of refrigerant.

  Refrigerants emitted in the course of normal operation of air-conditioning and refrigeration equipment.

  Releases of CFCs or HCFCs that are not used as refrigerants.

  Small releases of refrigerant that result from purging hoses or from connecting or disconnecting hoses to charge or service appliances will not be considered violations of the prohibition on venting.

• Don't pick me

List the four parts of the EPA Certification exam.

• Core

  Type I – small appliances

  Type II – high pressure and very high-pressure appliances

  Type III – low pressure appliances

• You are required to take these exams.

What is the definition of a small appliance?

• A small appliance is defined as a product that is fully manufactured, charged, and hermetically sealed in a factory with five pounds or less of refrigerant.

• little bitty

List the recovery levels for Type I, small appliances.

• 80% of the charge if the recovery device is manufactured before November 15, 1993.

  80% if the recovery device is manufacture after November 15, 1993 and the compressor in the appliance in non-operational.

   

  90% if the recovery device is manufacture after November 15, 1993 and the compressor in the appliance in operational.

  4'' hg vacuum for active recovery devices

• EPA EPA EPA

What is a non-pressurized container?

• A non-pressurized container does not have a pressure greater that 0 psig even after putting refrigerant in it. It does this by expanding in volume as the refrigerant is added.

• hmmm

What is the difference between system-dependent recovery devices and self-contained recovery devices?

• A system dependent recovery device depends on the system from which the refrigerant is being recovered to help move the refrigerant. Self-contained recovery devices do not rely on the system the refrigerant is being recovered from for their operation. They typically are small, specialized condensing units.

• ahh i didn't know that

List the recovery levels for Type II systems using a recovery system manufactured before November 15, 1993.

• 0 psig for very high-pressure refrigerants

  0 psig for systems with less than 200 pounds of R-22

  4” hg vacuum for systems with 200 pounds or more R-22

  4” hg vacuum for other high-pressure refrigerants regardless of the amount of refrigerant in the system

• That's a lot to remember
