What is a style of oil pulling for compressors? - correct answer -Liquid
injection, thermosiphon, water/ glycol
With impingement style oil separator what are the steps of separation -
correct answer -Impingement, change of direction, gravity, and
coalescing filters. 4 steps
Two-stage compression is considered to be? - correct answer -At least
two compressors compressing the gas in the series.
Which compressor may have safety springs internally for liquid? -
correct answer -Reciprocating
,Which compressor is commonly started first in starting up a two stage
system? - correct answer -The high stage compressor
Rotary veins are limited to what type of application and ammonia
refrigeration? - correct answer -Low stage booster applications of a two-
stage system.
What is a style of the condenser? - correct answer -Air cooled, water
cooled, evaporative cooled
Before a condenser converse a gas to a liquid, what must happen to the
gas? - correct answer -The gas must be De-superheated
Evaporative condensers - correct answer -Derive their heat rejection
capability from the evaporation of water.
,Where do you manually purge and condenser when it is off - correct
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? -
correct answer -From the lowest point (outlet drain) of a condenser,
with condenser running.
Liquid drain from the condenser is 82°F and head pressure is 182 psi G.
What is indicated? - correct answer -Portable noncondensible gases
What is the direction of flow through every condenser? - correct answer
-Refrigerant enters at the top, leaves at the bottom
Can wetbulb temperature affect the efficiency of an evaporative cooled
condenser - correct answer -Yes
, What conditions are associated with high head pressure? - correct
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? - correct answer -561 BTUs
A refrigerant line contains ammonia at the following conditions 80°F,
120 psi G - correct answer -The line contains Vapor
100°C is equal to - correct answer -212°F F=(C x 1.8) + 32. F=100 x 1.8 +
32 = 212°F
Copper tubing is never used with - correct 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 -
