PAPER FIRE SERVICE KNOWLEDGE
COMPREHENSIVE QUESTIONS AND ANSWERS
VERIFIED A+
◉ A refrigerant engineer was instructed to charge of 60-ton plant
with R134A Refrigerant. The refrigerant engineer will most likely
and the charging valve on the. Answer: Low pressure side of the
system
◉ A refrigerant engineer verifies that a chilled water pump is
cavitating. Of the following the most likely cause for this condition is:
Answer: Water leaks through the mechanical seals
◉ There is a decrease in the efficiency of a reciprocating compressor.
This mostly likely caused by: Answer: Low suction pressure
◉ The suction and discharge valve of the reciprocating compressor
are mounted as follows: Answer: Discharge valve on top of the valve
plate and suction valve below
◉ You are the engineer running a 2000 ton (steam-driven turbine)
centrifugal refrigeration system, a refrigeration system supplies
chilled water to a college campus with multiple buildings. While
, making your rounds you notice that the discharge pressure of your
condenser water pumps is significantly lower than the normal.
Which following action would you avoid taking: Answer: Put on an
additional surface condenser pump and lower the chilled water set
point
◉ A water pump is discharge against head 92 feet of water, this is
approximately to a pressure of: Answer: 40 psi
◉ Which one of the following will connect to the middle port on a
gauge manifold? Answer: Vacuum pump
◉ The most important reason for installing a muffler in
reciprocating refrigerant machine is: Answer: To contain the
compressor pulsation noise
◉ Of the following, the statement that most accurately characterize a
hermetic compressor is that it: Answer: Will have both the
compressor and motor enclosed is gas tight housing
◉ In the picture, the valve is in what position Answer: The valve is
cracked open
