Ground source heat pump air conditioning technology,owing to its outstanding advantages of energy saving,environmental protection and sustainable development,becomes one of the preferred solutions for air conditioning and heating projects,effectively promoting the development of geothermal heating technology.This paper outlines the carbon emission reduction mechanism of ground source heat pump,and proposes a method system for calculating carbon emission reductions of new ground source heat pump projects based on determining project boundaries,analyzing baseline scenarios,and constructing a mathematical model for calculating emission reductions.In a case study of a new ground source heat pump project at a hospital in Shijiazhuang City,the carbon emission reductions were calculated for two new sets of the underground tube type ground source heat pump units and cooling tower systems.Results indicated that the project of the case was estimated to achieve an average annual greenhouse gas emission reduction of 4 084 tCO2e.The proposed accounting methods and the presented case study are intended to offer a practical reference for promoting ground source heat pump carbon reduction products and the accounting of corresponding emission reductions.
