In a dry type (direct expansion)
evaporator, liquid refrigerant must
boil away as close to the end of the
coil as possible in order to:
The difference between the
temperature of the refrigerant
boiling in the evaporator and the
temperature at theevaporator outlet
is known as:
An expansion device that is stuck
open will cause:
When measuring evaporator
superheat on a commercial system
that has a long suction line, the
pressure reading should be taken at
the:
Superheat measurements are best
taken:
, Atechnician is checking the
superheat on a multi-circuit
evaporator and finds one of the
circuits has a superheat that is
higher than the others. This could
be caused by:
A TEV with an external equalizer is
used on:
Dry type evaporators operate most
efficiently with a superheat setting
of approximately:
An evaporator used to chill liquids
si operating with a normal
superheat setting, but the system is
not cooling the product properly.
Which of the following is the most
likely cause?
What time interval is required
between each superheat
adjustment?
Alow temperature evaporator used
for cooling space or product
refrigeration:
Some special applications use
aflooded evaporator (operated full
of refrigerant). nI order to maintain
the proper level of liquid
refrigerant, a
type metering device is used.
