Performance and economical efficiency of the combined cooling, heating and power (CCHP) system mainly depend on the system structure, operation strategy and choice of facility capacity. This paper proposes a structural configuration of the CCHP system with hybrid chillers, consisting of a combined electric and absorption chiller, whose electric cooling to cool load ratio varies according to different electric and thermal loads in every hour. A new operation strategy, based on the variational electric cooling to cool load ratio, for the CCHP system with unlimited and limited power generation unit (PGU) capacity is investigated. Given the proposed operation strategy, an optimization algorithm is adopted to determine the optimal PGU capacity. In addition, a case study of a hypothetical hotel in Victoria, BC, Canada is conducted to verify the feasibility of the proposed CCHP system structure and the corresponding optimal operation strategy.
Combined cooling, heating and power (CCHP) systems, which can also be referred to the trigeneration systems, are broadly employed in small-medium scale power systems in order to achieve economical efficiency and less contamination ,  and . The main idea of the CCHP system is to make use of the excess heat rejected from the power generation unit (PGU) to regenerate thermal energy that can be used to compensate for the building energy demand gap ,  and . CCHP systems have been widely introduced into various kinds of buildings, such as office buildings, hotels and hospitals  and .

A new structure of the CCHP system, whose cooling part consists of hybrid chillers, has been proposed in this paper. The electric cooling to cool load ratio is optimized according to different electric and thermal demands in every respective hour. Energy flow of this CCHP system is investigated as the foundation for the further operation strategy design. First we design the operation strategy with unlimited PGU capacity. The matching methodology is adopted when designing the operation strategy for the CCHP system with unlimited PGU capacity.
