Sensible Heat Ratio
This relationship between the conditions and quantity of the supply air can be
described using the analogy of maintaining a constant temperature within a
container of water.
In this illustration, the container of water is capable of absorbing heat. The
amount of heat it absorbs is called heat gain. To maintain the water
temperature at a constant 75°F, any heat gain must be offset by mixing cool
water with the water already in the container.
The rate at which this cool water is added to the container is determined by its
temperature. For a given water temperature there is a certain flow rate—
measured in gallons per minute (gpm)—that will offset the heat gain and
maintain the desired temperature in the container. If the water is warm, a higher
flow rate is required than if the water is very cold.
