홈페이지논문 초록 (Abstract)
It is very important to obtain a out-of season production in horticultural greenhouses corresponding with higher crop pri ces. A ground source heat pump system has been highly spotlighed as an energy efficient heating system for the greenhouse. This paper inve stigated the operating cost of the ground source heat pump system wit h the variation of generating temperature and designing methods fo r heating system of the greenhouse. Even though the COP of the ground source heat pump system decreased with an increment of generating tempe rature in heating mode, the operating cost could be reduced. By adopt ing the high temperature heat pump system and heat storage tank, it coul d be achieved to save energy and reduce the operating time of au xiliary oil heating system for producing good plant-growth in the green house.
