Read the first 7 Code Compliance flashcards as text

  1. What is the maximum refrigerant charge allowed in a self-contained air-conditioning system installed in a public corridor under ASHRAE 15?

    Answer: It is based on the room volume and the refrigerant's RCL

    ASHRAE 15 limits refrigerant charge in occupied spaces based on the room volume divided by the refrigerant concentration limit (RCL).

  2. Under EPA Section 608, which action is specifically prohibited when servicing refrigerant-containing appliances?

    Answer: Knowingly venting refrigerants to the atmosphere

    Section 608 explicitly prohibits knowingly venting Class I and II refrigerants to the atmosphere during maintenance, service, repair, or disposal.

  3. What is the primary purpose of a fusible plug installed on a refrigerant receiver?

    Answer: To relieve pressure by melting and releasing refrigerant if exposed to fire

    A fusible plug melts at a specified temperature when exposed to fire, allowing refrigerant to escape and preventing vessel rupture from pressure buildup.

  4. Under the International Building Code, what minimum clearance is required around refrigeration machinery for service access?

    Answer: 36 inches

    The IBC and IMC require a minimum of 36 inches of clear working space around refrigeration machinery to allow safe service access.

  5. A technician finds that a customer's R-22 system is leaking. Under current EPA rules, what must the technician do?

    Answer: Recover the R-22 and repair the leak; R-22 is still legal to use in existing equipment

    R-22 is still legal to use in existing equipment with reclaimed or recovered refrigerant; the technician must recover and repair per Section 608 rules.

  6. Which ASHRAE standard addresses energy efficiency standards for refrigeration systems and directly impacts code compliance inspections?

    Answer: ASHRAE 90.1-2022

    ASHRAE 90.1 sets energy efficiency standards adopted by most US building energy codes, governing minimum efficiency ratings for refrigeration equipment.

  7. What type of detector is required by ASHRAE 15 in a machinery room to activate emergency ventilation?

    Answer: Refrigerant vapor detector set to alarm at the refrigerant's RCL

    ASHRAE 15 requires a refrigerant vapor detector in the machinery room that triggers emergency ventilation when concentration reaches the refrigerant's RCL.
