Since 2009, the government has implemented Agriculture and Fishery Energy Utilization Efficiency Project as a way to mitigate running expenses by reducing heating costs of growing crop, to respond to climate change by using renewable energy. The volume of heat pump cooling & heating system, one of the support project facilities, is determined to support 70% of the largest load capacity considering the economics and the remaining 30% by existing diesel boiler. Accordingly, We analyzed the economics for a regional large glass greenhouse upon the outdoor temperature by variably adjusting the load sharing ratio of two heating systems.
1) By analyzing minimum temperature in winter for heating on 9,384m2 of glass greenhouses spread the Korea Rural Community Corporation in accordance with the standard drawings, we analyzed the economics divided into six regions, i.e. Gangwon and the Central Mountainous region(-17.4℃), the Central region(-12.9℃), the Southwestern region(-10.7℃), the Eastern coast region(-8.8℃), the Southern coast region(-6.4℃), Jeju-do region(-1.4℃).
2) When applying to respectively greenhouse heating load of 50%, 60%, 70%, 80%, 90%, to 100% for the capacity of the geothermal heat pump system, and to the rest of heating load for existing diesel-boiler, we analyzed the payback period. As a result, 1) geothermal heating system only 100%, Jeju-do region payback period to eight years was the longest. 2) we found that making lower rates of geothermal heating plants or cold regions are more economical at around 2 years for the best due to the shorter payback period on investment compared to other regions from the research.
