Effect of ground-coupled heat pump technique application on economic performance and emission reduction in swine farm in Beijing China

摘要

To find low carbon heating measures in swine farms in Beijing China, A study of swine houses with area of 920 m~2 in swine farms in Beijing China was conducted and economic performance, emission reduction of ground-coupled heat pump (GCHP) heating system, coal fired heating system and other heating systems were analyzed and compared. The results showed that the initial investment of ground-coupled heat pump system was more than that of the coal fired heating system, the relative running cost of the heating systems of ground-coupled heat pump, coal fired, electricity resistance and natural gas was 0.86, 1.00, 3.17 and 1.22, respectively. CO_2 avoidances of GCHP heating systems were 57% and 73%, respectively, compared with conventional coal fired heating system and electricity resistance heating.
