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.
