Study Guide

Objective

The student knows different types of heat exchangers, their typical applications and functional differences, as well as dimension and select a heat exchanger for the usual purpose of HVAC technology use. The student can explain the principles and forms of heat transfer in the case of a pipe and apply them in heat transfer calculations for pipes. The student is able to explain the principles of dimensioning of accumulators and to dimension and select accumulators.

Content
