A new isolated energy-supply system of gas engine-driven heat pump.

Author(s) : LI Y. L., ZHANG X. S.

Summary

In order to overcome the shortage of air conditioning load and the irrational thermal efficiency of gas engine in a mini-distributed energy-supplying system, a new isolated energy-supplying system of gas engine-driven heat pump is presented, also the principles, characteristics and application of the system are delivered. After analyzing the three different operating modes of the system, mathematical models of energy transmission about the three operation modes are established. The simulation results show that when the part-load rate of the gas engine is between 70-80%, the thermal efficiency of the power system is higher, and the maximum can be more than 0.4. Furthermore, among the three different operating modes, the thermal efficiency of the power system is highest in the operating mode C, less in the operating mode A, the least in the operating mode B. Notably, in the operating mode C, comparing with the conventional gas engine-driven heat pump system, the average increase of the thermal efficiency of power system can be about 0.035.
