In a time of increasing energy and water demand, engineers will
need to pay more attention to designing innovative energy efficient
systems together with conservation of natural resources in order
to minimize their environmental impact.
In hot and humid climates, considerable amount of energy is
used in the conditioning of outdoor air, which involves cooling
and dehumidification. Comparing to typical office building, HVAC
systems in facilities such as hospitals, laboratories or operating theatres
can consume five to ten times more energy [1]. This higher
energy use is due to many factors including provision of large
amounts of 100% outside air, continuous operation, requirement
for stringent internal parameters, high fan energy, etc. At the same
time, imbalance seems to exist between the current cost of water
and the actual value of that water to the society and environment.
Even purified and distributed over long distances, water is available
for such a low cost that it usually consumed irrationally, i.e.
irreversibly wasted. With this significant energy and water usage,
designing innovative efficient systems will be essential.
In temperate climates, the amount of latent load is variable
throughout the year which implies inconsistent condensate
