Balance point

In any thermal heat exchange process, a mixture of two energy flows will result in a new stage or phase called the balance point. Here, a common temperature, humidity or enthalpy is reached. The mixture of hot and cold water in a tap is a brilliant example of a balance point. It requires the adjustment of two flows to achieve a required temperature.

The balance point can be illustrated by a simple formula stating the energy flux for each of the two flows. In HVAC applications, the Balance point is calculated and illustrated in a Mollier IX diagram. A mixture of hot and cold air with a given humidity will result in a mixture with a new temperature and humidity.

Grundfos circulator pumps ensure a correct mix for balance-point heating and air conditioning.
