Heat Exchangers
and mixing devices
Heat exchangers are devices which
transfer heat between different fluids
Mixing devices (also called open heat
exchangers) combine two or more
fluids to achieve a desired output,
such as fluid temperature or quality

Review: Tds Equations
Entropy is a property.
The properties are independent of path.
We can use the Tds equation to calculate
the entropy change between any two states

Refrigerators and heat pumps
We can show in a manner parallel to
that for the Carnot corollaries:
1. The COP of an actual, or irreversible,
refrigeration cycle is always less than the
COP for a reversible cycle operating
between the same two reservoirs.

Third Law of Thermodynamics
Absolute Entropy
The entropy of a pure crystalline substance
at absolute temperature is zero.
The third law provides an absolute
reference point for entropy.
The entropy determined relative to this
