Alfa Laval spiral heat exchangers 5 Waste heat recovery The secret is the true counter-current flow. It enables crossing temperature situations where the cold fluid can be heated to temperatures very close to those of the hot fluid. The closer the temperature approach between two fluids, the more heat is recovered. This effect is enhanced by Heat Exchanger Flow:Cross flow, Parallel flow, Counter Jan 26, 2010 · A counterflow heat exchanger has the hot fluid entering at one end of the heat exchanger flow path and the. cold fluid entering at the other end of the flow path. Counter flow is the most common type of liquid-liquid heat exchanger, because it is the most efficient. A double pipe heat exchanger is usually operated as a counter flow heat exchanger, as shown in the diagram at the left.
the counter flow heat exchanger design is the most efficient when comparing heat transfer rate per unit surface area. The efficiency of a counter flow heat exchanger is due to the fact that the average T (difference in temperature) between the two fluids over the length of the heat exchanger is maximized, as shown in Figure 4. How To Size A Waterside Economizer Part 5:Why Plate May 07, 2020 · This counter flow pattern yields a high rate of heat transfer, providing as close as a two degree approach between the condenser water and the chilled water. The counter flow design also allows a temperature cross (the difference between the condenser water and the chilled water temperature at their respective outlets) which you could never get
When a heating load begins, the heat recovery condenser water pump operates, starting water flow to the heat recovery condenser. As the heat-recovery condenser entering-water temperature (T2) rises and causes the condenser-water pump to start, the diverting valve (V2) to close, and cooling-tower fans to modulate.

CROSSFLOW PLATE HEAT. EXCHANGER. In a crossflow heat exchanger heat is transferred directly from the outlet air to the make up air through the separating walls of the heat exchanger. Both sensible and latent heat may be transferred. Latent heat
