Operational analysis on CCHP coulped with river water-source heat pump system in Chongqing

Combined with field measures and test data from third party, analyses the actual operational performance of a combined cooling heating and power system（CCHP）coupled with river water-source heat pump in Chongqing. The measure results show that power generating efficiency, exhaust heat recovery rate and primary energy ratio of CCHP are 35%, 52.7% and 82.3%, respectively. The cooling seasonal energy efficiency ratio and heating seasonal energy efficiency ratio of river water-source heat pump system are 3.85 and 3.97, when running at 55.6% of cooling load and 89.3% of heating load, respectively. Compared with actual operational strategy, the energy consumption can be decreased by 39.9% with design strategy.
