The
pressure-temperature Relationship
The
pressure-temperature relationship is the basis of a number of effects
that can be observed not only in the condenser and compressor, but
also in an ordinary cylinder of refrigerant. An explanation of the
pressure-temperature relationship at this point might prove useful.
EXERCISE
: Two
cylinders each contain a mixture of R22 vapour and liquid at the
same temperature (20°C).
In
the first cylinder, the depth of liquid refrigerant is four times
that of the liquid refrigerant in the second cylinder.
Knowing
that the pressure in the first cylinder is 8 bar, what will be the
pressure reading (in bar) shown on a gauge connected to the second
cylinder?
