Operation of Heat Exchangers
Operation of Heat Exchangers
This Demonstration illustrates the effects of various input parameters on parallel-flow and counter-flow heat exchangers. It shows the temperature distribution and calculates the total heat transfer , the effectiveness , where =-, and the number of transfer units , for both cases. By varying the input parameters, this tool lets you compare and understand the effects in these types of heat exchangers.
