Direct injection mixing, whether accomplished using a two-way valve or variable-speed pump as the injection control device, provides the highest temperature difference between the supply and return injection risers.

Question

Quizplus · Accepted Answer

Direct injection mixing can achieve a higher temperature difference between supply and return injection risers compared to other mixing methods, such as recirculation mixing. This is because the injection control device (two-way valve or variable-speed pump) allows for more precise control of the amount of hot and cold water being mixed together.
