Presence of which of the following elements will reduce the
stability of the ozone depletion organic refrigerant compounds:
Chlorine
Bromine
Hydrogen
,3|Page
All of the Above - ANSWER-Hydrogen
Chlorine and Bromine are considered as the elements
responsible for the depletion of ozone layer at stratosphere.
CFC compound are highly stable at lower atmosphere and
have higher lifetime. Therefore they reach stratosphere and
depletes the ozone layer. Presence of Hydrogen element in
organic refrigerants such as HCFCs and HFCs results in
decomposition at lower atmosphere. Therefore these
elements have lower lifetime and cannot pose threat to ozone
depletion.
If the label identifying the refrigerant is missing, then which
method is used to identify the type of refrigerant? - ANSWER-
Pressure-Temperature method
, 4|Page
Saturated refrigerants have a specific pressure rating at a
specific temperature. If both these parameters are measured,
correct refrigerant can be determined by looking at pressure-
temperature chart
References to the pressure/temperature chart for determining the
type of refrigerant are only valid if the _____ is known: -
ANSWER-Temperature
Sale of which of the following refrigerants are not limited to
technicians:
HCFC
HFC
CFC
All the refrigerants are restricted - ANSWER-HFC
