홈페이지논문 초록 (Abstract)
Good plant-growth conditions can be achieved by means of using greenhouses. One of the main issues in greenhouse cultivation is energy savings through the development of high efficient heating and cooling system. GSHPs are one of the recommended systems to cope with this pending need. The aim of this study is to investigate the hea ting performance of ground source multi-heat pump system installed in a greenhouse under part load conditions. Daily average heating COP of the heat pumpunit was very high by at least 7.4, because of re latively large condenser, evaporator, and mass flow rate through grou nd loop heat exchanger. However, the system COP, overall heating coe fficient of the performance of the system with heat pump unit and GLHX, decreased drastically due to relatively large power consumption of ci rculating pump under part load condition. It is suggested that the te chnology to enhance the performance of the ground source multi-heat pum p system for a greenhouse under part load conditions should be developed .
