  • The SME will be awarded a rebate on the loan of up to 30% if achieved 50% on energy savings

  • The SME will be awarded a rebate on the loan of up to 30% if achieved 50% on energy savings

  • Floating condensation

    In an energy optimal solution, the condensation temperature varies according to the outside temperature instead of being constant over day/week/year. The condensation temperature is of major importance for the electrical consumption in the refrigeration plant.

  • Production of cold water

    In the Vietnamese seafood industry, a lot of ice is used to produce chilled water, where icesimply is mixed with water. This is a very inefficient way of producing chilled water, and a lot of excess energy is used because of this method.

  • Correct pressure level

    Cooling capacity is an expensive resource, and the lower the temperature, the more expensive it gets. It is therefore of major importance that the refrigeration plant delivers cooling at correct temperature, and not lower than necessary.

  • Change of flat belts to high efficiency belts

    Piston compressors in the Vietnamese seafood industry are normally driven by belts of the flat belt type. It is not uncommon that these belts have waste of power in the ratio of 10%, both because they are inefficient and not properly maintained.

  • Desuperheater

    Desuperheating of refrigerant gas takes place in all refrigeration plants. The question is whether the heat released can be utilized. Approximately 12% of the condensation energy, roughly equivalent to 60% of electricity used by the compressors, can be used to heat water up to temperatures around to 60˚C for cleaning purposes etc.

  • No use of capacity slides

    All screw compressors have lower energy efficiency at part load, and no compressors are running full capacity all the time. How part load operation takes place is of significant importance on the overall energy efficiency for the refrigeration plant.
