Answer:
the vapor will
change to a liquid.
Q: All refrigeration units have some effect on both

Q: Superheat takes place in the evaporator and is
Answer:
determined by subtracting the saturation
temperature (low side gauge temp) from the suction line temperature (read on a
digital
thermometer strapped on the suction line).
Q: If the superheat number is higher than required,
Answer:
slowly add refrigerant to lower the
superheat.
Q: If the superheat is lower than required,
Answer:
remove refrigerant to raise the superheat.

Q: When charging with superheat there is usually a margin of error of
Answer:
+/- 2 degrees in the
acceptable range.
Q: To Find target superheat
Answer:
Measure the indoor wet-bulb temperature at the return air to
determine the amount of heat in the structure.
Than, measure the ambient dry-bulb temperature at the condenser.
Q: To find operating superheat
Answer:
Convert the low-side pressure to temperature and subtract it
from the measured vapor line temperature at the condensing unit or compressor.
