A dairy has many processing units that are all operating at different temperatures and therefore many heat exchangers are needed in a dairy. Thus a dairy can be drawn as a potential network of heat exchangers. For a first evaluation a generic dairy is the baseline of this calculator that will be used for the calculations. This calculator will provide two different outcomes.

1. A dairy can evaluate how much energy savings can be created by optimizing their heat exchanger network.
2. Based on inserted data a dairy can get information by comparing their current implemented technologies which green technologies or processes can generate more energy savings within the dairy. A recommendation will be provided.

The green or energy efficient technologies cover solar energy + biomass boiler , heat pump , absorption chiller , well water and CHP .
