Cogeneration waste heat utilization

In addition to the system that uses the waste heat from the generator as hot water, the waste heat is converted to cold water and used for cooling and air conditioning greatly improvingthe overall annual efficiency of the cogeneration system.

Cogeneration waste heat utilization

Sports center　(Natural gas fired cogeneration)

  • Business type
    Sports center
    Model
    Water fired chiller 100RT(2 units)
    Available heat
    1,005kW
    (waste hot water)
    Chilled water application
    Factory air conditioning
    Energy saving
    408,800(kWh/year)

Proposal content

Added a waste heat utilization machine (cooling output 704kW) to the existing electric air conditoner(cooling output 1,408kW).
Electricity consumption and CO₂ emissions are reduced by covering the base operation of existing equipment with waste heat utilization equipment.

  • Business type
    Plastic production factory
    Model
    Water fired chiller (100RT)
    Available heat
    504kW
    (waste hot water)
    Chilled water application
    For cooling mold
    Energy saving
    425,700(kWh/year)

Proposal content

Added a waste heat utilization machine (cooling output 352kW) to the existing electric chiller(cooling output 704kW).
Electricity consumption and CO₂ emissions are reduced by covering the base operation of existing equipment with waste heat utilization equipment.

Winery　（Biogas cogeneration）

  • Business type
    Winery
    Model
    Water fired chiller (50RT)
    Available heat
    252kW
    (waste hot water)
    Chilled water application
    For cooling wine cellar
    Energy saving
    147,000（kWh/year）

Proposal content

By using the chilled water generated by the waste heat utilization machine to cool the wine storage rroom, it is possible to control the temperature of the wine storgage room while suppressing the increase in electricity consumption.
