Heating & Air Circulation Flashcards
What are the three mechanisms of surface loss?
evaporation, convection, and thermal radiation
Evaporation
occurs at the surface of the water and accounts for 50% of all heat losses.
Convection
occurs when heat from the water’s surface is transferred to the cooler surrounding air.
thermal radiation
A warm pool will radiate heat to a cooler surrounding air.
Conduction
the movement of heat through the in-ground pool’s structural components.
Which heat losses occur at the surface?
Evaporation, Conduction, and Radiation
In indoor pools, the humidity should be kept in what range?
40 - 60%
The air temperature in indoor pools should be kept where in relation to the pool water?
+2-4 degrees
Air circulation is just as important as water circulation for indoor pools.
True
In a system with a heat exchanger, the pool water is indirectly heated by:
Domestic hot water
Which mechanism causes the least amount of heat loss?
Conduction
