Economic Performance Study on the Application of Ground Source Heat Pump System in Swine Farms in Beijing China

To investigate the economic performance of applying the ground source heat pump system in swine farms in Beijing China, initial investment and operating cost of ground source heat pump (GSHP) heating and cooling system, coal fired heating system (CFH), wet curtain fan cooling system (WCFC), air conditioner heating and cooling system (AC) were analyzed and compared. The results showed that the initial investment of GSHP heating and cooling system was higher than that of the CFH system integrated with WCFC system, the relative operating cost of the heating systems of GSHP, CFH and AC was 0.94, 1.00 and 0.98, respectively. The relative operating cost of the cooling system of the GSHP, WCFC and AC system was 4.50, 1.00 and 6.38, respectively.
