INDEX SYSTEM OF GROUNDWATER SOURCE HEAT PUMP SYSTEM IN FEASIBILITY
The famous methods of systems engineering, Analytic Hierarchy Process (AHP) and Fuzzy Comprehensive Evaluation (FCE), are used in this paper. And the index system of Groundwater source heat pump (GWSHP) system in feasibility is established, which is composed of four layers: objective (level A), criteria (level B), index (level C), and sub-index (level D). A comprehensive assessment of GWSHP system is made based on some key factors, such as, hydrogeology condition, air-conditioning system load characteristic, groundwater injection, and design of heat source wells. Finally, the index system of GWSHP system in feasibility is validated by a practical project. The paper supplies references to the designers and managers of the GWSHP system, especially in choice and design.
