Abstract
A coupled heating system with combined cooling heating and power (CCHP) system and ground source heat pump (GSHP) is proposed in this paper. The system adopts the internal combustion engine (ICE) to drive the generator to generate electricity, then the jacket water from ICE is used to absorption heat pump and/or preheats GSHP to increase the coefficient of performance (COP), and the exhausted gas is sent to the high pressure generator to drive the absorption heat pump. The mathematical models of components were established, through the analysis of the relationship between the various devices and operational characteristics. Then, the performance analysis of the system is carried out under the condition of variable jacket water distribution ratio and variable electricity load. The results show that the energy efficiency and exergy efficiency of the system are the largest, 128.24% and 34.21% at the heating work condition respectively.
