- Combined Cooling and Power System Feasibility
ABSTRACT: Combined Cooling and Power (CCP) system has recently become an interesting technology as distributed power generation and district cooling system has been viewed as a solution for mega project and new city development. The system clearly provides benefit for national supply side management and efficiency. However, investment on CCP system is high and is very hard to compete with conventional system and electric chiller. This paper describes integration of demand side management in order to support CCP feasibility with 15% internal rate of return, including charge rate calculation formula and a success case study.
The well-known concept of Combined Heat and Power (CHP) system has been proven as high energy efficiency energy recovery system that recovers waste heat from power generation to another useful product, such as heating and cooling energy. The most familiar CHP process is the topping cycle which feeds fuel (Oil, Natural Gas, LPG, Biogas etc.) to prime mover that coupling with generator to produce electricity and recover heat from the flue gas for another product such as steam or chilled water or both. In hot climate, energy demand for the commercial building is electricity for utility and cooling system. Therefore, the Combined Cooling and Power (CCP) is another word that refers to the CHP system that produces both the electricity and chilled water.
