Energy optimisation
Methods for energy optimisation are closely linked to advanced, but also practical use of thermodynamics.
The following four basic elements are used:
|
Refrigeration and energy needs
Minimisation
Optimal timing (storage) |
System design
Utilise "free heat/free coldness"
Utilise heat exchanges between steps
Select appropriate working agents |
| Dimensioning
Minimal pressure loss and differences in temperature for pipe heat exchangers
Maximum (exergy) performance levels for compressors, fans and pumps |
Regulation
Continuous capacity regulation
System-optimal distribution of capacity between compressors, fans and pumps |
Frequently, several optimisation parameters have opposing effects, which is why optimisation requires knowledge of the quantitative significance of the loss phenomena.
The above-mentioned elements have been tested in energy optimisation projects ranging from household refrigerators and supermarket refrigerator installations to industrial refrigerator plants.
