Updated Basic Refrigeration Questions With Correct Answers

At the condenser, refrigerant enters as - ANS Superheated gas and leaves as high pressure liquid Highly superheated vapor - ANS If you were running three compressors, what is the state of the refrigerant leaving the third compressor? Latent heat - ANS When changing water to ice, what must be removed? Touch it to a bucket of ice/ice water - ANS If you just purchased a thermometer and need to check to see if it's working properly, how would you check it? Heat of fusion - ANS when water changes to ice 360,000 BTUs per hour - ANS How many BTU's would be removed in a 30- Ton system? Heat of fusion - ANS 1-ton of Ice @ 32 degrees in 24 hrs 1 Horsepower - ANS 746 watts or 33,000 ft/lbs per minute 2 or more refrigerants - ANS Azeotropic The heat that boils of in a condenser - ANS Latent heat, sensible heat, and superheat A refrigeration unit is measured in - ANS BTUs The compressor outlet and the orifice of the metering device - ANS The dividing line between the high and low sides of the refrigeration system is: outside of the evaporator - ANS Refrigerant superheat takes place: superheated vapor and warm subcooled liquid - ANS the state of refrigerant as it leaves the compressor and as it leaves the condenser superheated gas - ANS Dry vapor above it's boiling point. the state of refrigerant is it enters and exits the compressor - ANS Low Temp. vapor in and high temp. vapor out. Raising Pressure - ANS A pump affects the pressure of a fluid or gas by: A reduction in water pressure at the condenser unit - ANS An operator is running two centrifugal condenser water pumps in parallel, one of the pumps is at maximum pumping rate, if the operator throttles back on the discharge valve of the other pump, the most likely effect would be: 1.2 of design pressure (at least) - ANS As an RMO in charge, you are requested to replace the ga
