Trigeneration (CHPC) is the simultaneous process of cooling, heating and power generation from only one fuel input. Trigeneration provides a third form of energy: cooling energy in addition to heat and power. Trigeneration systems – are typically a combination of cogeneration plants and chillers to produce electricity, heat and cooling energy in one process. Waste heat is thereby converted tochilled water, either by absorption or adsorption chiller technology. The by-product is waste heat, which is then directed to boiler and absorption chillers for cooling, hot water etc. Trigeneration is the process by which some of the heat produced by a Cogeneration plant is used to generate chilled water for air conditioning.
CHPC systems consist of a power system which can be an internal combustion engine driven by afossil fuel or biofuel driven systems coupled to a generator which produces electricity. A heat recovery system recovers heatfrom the power system and exhaust gases to be used for heating applications.
