What is a style of oil pulling for compressors? - ANSWER-Liquid
injection, thermosiphon, water/ glycol
With impingement style oil separator what are the steps of
separation - ANSWER-Impingement, change of direction, gravity,
and coalescing filters. 4 steps
Two-stage compression is considered to be? - ANSWER-At least
two compressors compressing the gas in the series.
Which compressor may have safety springs internally for liquid? -
ANSWER-Reciprocating
Which compressor is commonly started first in starting up a two
stage system? - ANSWER-The high stage compressor
,2|Page
Rotary veins are limited to what type of application and ammonia
refrigeration? - ANSWER-Low stage booster applications of a
two-stage system.
What is a style of the condenser? - ANSWER-Air cooled, water
cooled, evaporative cooled
Before a condenser converse a gas to a liquid, what must happen
to the gas? - ANSWER-The gas must be De-superheated
Evaporative condensers - ANSWER-Derive their heat rejection
capability from the evaporation of water.
Where do you manually purge and condenser when it is off -
ANSWER-From the highest point (inlet gas)of the condenser, with
condenser off or isolated
Where should on auto purger be piped from on the condenser? -
ANSWER-From the lowest point (outlet drain) of a condenser,
with condenser running.
,3|Page
Liquid drain from the condenser is 82°F and head pressure is 182
psi G. What is indicated? - ANSWER-Portable noncondensible
gases
What is the direction of flow through every condenser? -
ANSWER-Refrigerant enters at the top, leaves at the bottom
Can wetbulb temperature affect the efficiency of an evaporative
cooled condenser - ANSWER-Yes
What conditions are associated with high head pressure? -
ANSWER-Excessive energy used and compressor wear
In order to convert 1 pound of saturated NH3 liquid to saturated
NH3 gas, approximately how much heat must be absorbed into
the liquid at saturation conditions? - ANSWER-561 BTUs
A refrigerant line contains ammonia at the following conditions
80°F, 120 psi G - ANSWER-The line contains Vapor
, 4|Page
100°C is equal to - ANSWER-212°F F=(C x 1.8) + 32. F=100 x
1.8 + 32 = 212°F
Copper tubing is never used with - ANSWER-Ammonia
A compressor is probably matched with a drive motor on a system
that works at a -10°F evaporating temperature. If the room
temperature is allowed to go up to +30°F and then is pulled back
down to -10°F then - ANSWER-The drive motor may pull more
ramps while pulling down, the compressor efficiently will drop
while pulling down.
1% concentration of Ammonia is equal to what in parts per
million?
A. 10 PPM
B. 100 PPM
C. 1,000 PPM
D. 10,000 PPM - ANSWER-D. 10,000 PPM
