In this chapter, a method of matching chillers to prime movers is presented. CCP configurations with and without backup cooling are described, along with first-order estimates of the energy efficiency of each combination of configuration and prime mover. Some experimental results for micro combined cooling heating and power (CCHP) are presented. Based on the analytical and experimental work, it is concluded that CCP and CCHP performance depend heavily on the choice of prime mover. CCP systems based on fuel cells can use less energy than grid-driven electrical cooling systems. CCP with combustion-based prime movers has potential to save energy in off grid applications
