When the condensing temperature at the compressor head
reaches 350 °
the compressor is sure to fail because : - ANSWER-the oil
turns to carbon
deposits
A system that runs at a superheat of 1 ° F will likely : - ANSWER-
will likely
allow liquid refrigerant back to the compressor
at some point
. Which of the following is the best way to recharge a cap tube
system after
you have serviced it and replaced the drier with one that is
physically larger ? -
,ANSWER-charge the system until you obtain the proper
subcooling and
Superheat
When converting a system from R502 to R404A you : -
ANSWER-can use
the same R502
TEV
. The new interim refrigerants R401A R401B , R409A all have
more heat carrying capacity This means that : - ANSWER-A. A
little less refrigerant will be needed
B. the system must be perfectly tuned since there will be more
heat of compression
C. you should have some good base line data with the old
refrigerant if possible
before you install the new refrigerant if at
all possible
. R134A : - ANSWER-A. has less heat carrying capacity than
R12 at lower
temperatures
.
B. can use the same expansion valve
as R12
C. must use
Alkylbenzene oil
, A condensing unit located in a restricted space will usually
run higher than
normal head pressures due to : - ANSWER-recirculating
hot air off of the
condenser
When checking for correct superheat on a cap tube system : -
ANSWER-The
box must be close to normal operating
temperature
A water cooled condenser that is operating properly will have :
- ANSWER-
discharge water 10 ° warmer than the converted
condenser temperature
. When the condensing unit is off , the water regulating valve
for the water cooled condenser - ANSWER-B. should taper off
the water flow rate , and stop completely as pressure reduces
. The voltages to a three phase compressor must be balanced
This means that the maximum allowable voltage difference
between terminal combinations can be : - ANSWER-2 % of the
average of the three voltage measurements
. A compressor starts and runs for a while and kicks the 30
amp circuit breaker . The FLA rating is 7 amps . When it starts
you measure 30 amps , and the current drops in a few seconds
