Trigeneration or combined cooling, heat and power (CCHP) is the production of electricity, heat and cooling in the one process.
Trigeneration or combined cooling, heat and power (CCHP) is the production of electricity, heat and cooling in the one process. Some of the heat produced by a cogeneration plant is used to generate chilled water for air conditioning or refrigeration. Hot water from the cooling circuit of the cogeneration plant serves as drive energy for the absorption chiller.  Absorption chiller technology represents an optimal solution for a year-round efficient source of cooling and heat. Trigenereation systems can be effectively used in hotels, conference centers, office buildings, hospitals and different industries (e.g., food, chemical, computer industry) where the cooling eletricity and heating are required.

Advantages of trigeneration systems over conventional refrigeration technology:

  • Operated with heat, utilizing inexpensive “excess energy”
  • No moving parts in absorption chillers, no wear and therefore low maintenance expenses
  • Noiseless operation of the absorption system
  • Low operating costs and life-cycle costs
  • Water as refrigerant, no use of harmful substances for the atmosphere
