Heat exchangers. what is approach temperature? : engineeringTypically we have a "critical" side and I always see approach defined in terms of its leaving condition. However, I disagree with the other commenter regarding what is a typical temperature. Approach is very process dependent. On an chilled water coil 10 F is common. On a water to water plate and frame HX 1-2 F isn't hard to get.

FAQ | XchangerSuch a heat exchanger is said to have a "10 F approach temperature." The term "approach temperature" is used because it will stay fairly constant with changes in both inlet process and service fluid temperature. As the approach temperature diminishes, the size (and cost) of the heat exchanger will eventually increase exponentially.
