Basic calculating formula for recovered heat quantity
Q=AUTm
Q: Recovered Heat quantity (/h)
A: Effective heat transfer area ()
U: Overall coefficient of heat transfer (/ hc )
Tm: Effective average temperature difference (c )

Effective heat transfer area: A()
Installing as many tubes inside the heat exchanger increases the effective heat transfer area, while increasing dead zones decreases the effective areas proportionately.Therefore, the performance of heat exchanger depends upon how to effectively convert to the effective heat transfer area.

Comparison diagrams of effective heat transfer areas
The following phenomena take place, as flowing fluid is characteristics of flowing to the lower pressure direction .
The primitive form of Figure 2, which has no baffle plate, has wider dead zones.
The common form of Figure 3 and 4, which have baffles reduces dead zone areas to some degree.
Our waste water heat recovery equipments as shown Figure 1 has no dead zone area, enabling to attain complete flows, resulting in maximizing the effective heat transfer areas, having a far superior effective efficiency compared to other heat exchangers. (Patent right number 14894).
