Enter the fluid data and enter 5 of the 6 available inputs under flow rates and temperatures.
To approximate the results of a heat transfer system.
They will also calculate the number of tubes needed for a shell and tube heat exchanger and to calculate the pipe length needed for a double pipe heat exchanger.
A storage calorifier as shown in figure 2 13 1 is constructed differently it usually consists of a hot water storage vessel with a primary heating coil inside.
Select the appropriate heat exchanger from the table based on the total btuh required.
Determine the total btuh required using guidance from your radiant tube supplier for the snow melt system.
These templates use s i.
To select a heat exchanger for a snow melt application.
1 1 example for finding cold fluid outlet temperature.
1 4 example for plate type heat exchanger heat transfer area calculation.
Rather than using an adjustable design with replaceable plates like the wesplate these brazed plate heat exchangers cannot be modified so correctly sizing a unit is very important.
The heat exchanger in this application isolates the glycol loop from the boiler water.
A shell and tube heat exchanger used to heat water for space heating using either steam or water is often referred to as a non storage calorifier.
It is then required to compare h calculated.
Fortunately wessels has produced a few easy to use charts for sizing wespac brazed plate heat exchangers based on use case scenarios like radiant floor.
