Trigeneration or trigen is the simultaneous production of mechanical power (often converted to electricity), heat and cooling from a single heat source such as fuel or solar energy. As with cogeneration, the "waste heat" byproduct that results from power generation is harnessed, thus increasing the overall efficiency of the system.
Trigeneration can also refer to systems involving the production of Electricity, Heat/Cold AND some Product (mainly chemicals)
The residual heat that is obtained is the sum of the produced one for the generation of electricity, more the removed one of the process of refrigeration. With that heat quantity is obtained pluss though to minor temperature, with the disadvantage of which the possible applications of this one heat can be turns reduced.
In the summer epoch, the heat demand goes down considerably, that´s why the heat produced in the equipments of cogeneration can take advantage to generate cold for air conditioned necessarily in this epoch. On this way three types of energy are obtained from a primary energy (natural gas), together with an important economic saving and a good alternative for the environment.
