As the Co-Generation & Tri-generation optimises energy supply to all customers, the benefits for the users are abundant:-

  1. On site high efficiency production of power, heat and cooling.
  2. Significant reduction in energy costs.
  3. Lower fuel cost for applications.
  4. Lower emissions to the environment, in particular of CO2, the main greenhouse gas compared to conventional electrical generators and onsite boilers.
  5. Lower electrical usage during peak summer demand.
  6. Engine heat can be used to produce steam of hot water for onsite use.
  7. Significant reductions in greenhouse gas emissions.
  8. No harmful chemical pollutants since water is used as the refrigerant.
  9. Beneficial for improving building’s energy efficiency ratings

Gas engine Co-Generation and Tri-generation systems are highly efficient based upon the efficiency of conversion of the fuel gas to useful outputs.

Firstly via the combustion of the gas in the engine’s cylinders and their resulting action in the turning of the engine’s crankshaft, the energy in the fuel gas input is converted into mechanical energy. This mechanical energy is in turn used to turn the engine’s alternator in order to produce electricity. There is a small amount of inherent loss in this process and in this example the electrical efficiency of the engine is 40%. The diagram below illustrates this concept.

In comparison with conventional refrigerants, absorption based refrigeration technology offers the most established environmental solution for reduced emission air conditioning systems:-

  1. Utilises relatively inexpensive ‘excess energy’ as operated with heat making it economically viable.
  2. Production of electricity that can be fed into the power grid or used to cover the plant’s electricity requirements.
  3. No moving parts, there for there is no wear and maintenance costs are low.
  4. Noiseless operations.
  5. Low operating costs and lifecycle costs.
  6. Using water as a refrigerant replaces the use of ozone damaging substances.
