Energy efficiency and economic feasibility of CCHP driven by stirling engine

This paper deals with the problem of energy e.ciency evaluation and economic feasibility analysis of a small scale trigeneration system for combined cooling, heating and power generation (CCHP) with an available Stirling engine. Trigeneration systems have a large potential of energy saving and economical e.ciency. The decisive values for energetic e.ciency evaluation of such systems are the primary energy rate and comparative primary energy saving eDqT, while the economic feasibility analysis of such systems relates the avoided cost, the total annual saving and payback period. The investigation calculates and compares the energy saving and economic e.ciency of trigeneration system with Stirling engine against contemporary conventional independent cooling, heating and power, showing that a CCHP system saves fuel resources and has the assurance of economic
