The optimization costs for your plant depend on various specific data:

• type of compressor
• geographic location of your plant
• as well as other plant-specific parameters

Estimate of energy savings through integration of the phiControl solution:

Using the following savings equation, which considers the theoretical basics of thermodynamics as well as experience values from day-to-day operating procedures, you can easily estimate the possible energy savings potential [MWh/year] of your refrigeration plant.

Savings[MWh/year] =            (8 – 0.3 ∙ Tmin[°C]) ∙ Pelec[kW] ∙ E[%/year]

The following parameters are required for the use of this savings equation for compression chillers:

• electrical output of compressors Pelec [kW]
• minimal coolant temperature after recooling Tmin [16...20 °C]
• average workload of the plant E [%/year] (utilized capacity[days]/max. capacity [days])

Example

The following example of a compression chiller illustrates the use of the savings equation. For a plant with the following parameters:

• electrical compressor output Pelec = 900kW,
• minimal technological coolant temperature after recooling Tmin=20°C
• average workload of the plant E = 30%/year

The equation results in an annual savings potential of ca. 590 MWh/year. For a detailed calculation of the savings potential, additional values such as type of compressor, geographic location of the plant, and other plant-specific parameters are required. In the near future, it will be possible to carry out these calculations with our Online Savings Calculator.

This calculation serves as an example. When calculating costs, it is always necessary to consider the individual project. Please contact us, we will gladly calculate your savings potential and present you with an offer for remodeling → contact
