Trigeneration is a booming power production technology where three energy commodities are simultaneously produced in a single integrated process. Electric power, heat (e.g. hot water) and cooling (e.g. chilled water) are three typical energy commodities in the trigeneration system. The production of three energy commodities follows a joint characteristic. This paper presents a Lagrangian relaxa...

An efficient way for producing power, heat, and cooling while reducing CO2 emissions is through trigeneration. The emitted CO2 from trigeneration plant can be further reduced by producing biochar, which contributes negative carbon footprint to the system through sequestration of biomass carbon as char. This requires a gasification process to be added in the trigeneration system to produce bioch...

A solar trigeneration system, based on photovoltaic-thermal (PV/T) collectors, photovoltaic (PV) modules and a heat pump unit for heating and cooling, is modelled to forecast the thermal and electric yields of the system. The aim of the trigeneration system is to provide enough electricity, domestic hot water (DHW), heating and cooling power to meet the typical demand of an urban single family ...

The object of this research is an economic analysis of trigeneration systems (or Combined Cooling, Heat and Power CCHP) through a calculation model developed for applications in the field of large retail sector. Particular attention has been given to the validation of Third-Party Financing (TPF) projects. The analysis is carried out in comparative form, considering all the existing variants of ...

Integration of thermoeconomics and Life Cycle Analysis was carried out within the framework of an Environmental Management Information System. This combined approach identified where environmental loads were generated and tracked environmental loads throughout the system, allowing for a more precise understanding of operational activities. A trigeneration system was modeled, providing electrici...

the present study analizes a trigeneration system based on an internal combustion engine and a steam ejector refrigeration system from an energy point of view.
