Abstract
Taking an office building in Qingdao as the research object, the optimal operation of the solar coupled ground source heat pumps system using frequency conversion technology at load side and source side is studied, The possibility of variable flow operation of air conditioning water system and the control strategy of variable frequency pumps are analyzed. The selection of the equipmets is completed based on the hourly load of the office building through the year. Based on the dynamic simulation software, the simulation model of solar coupled ground source heat pumps is established. The results show that the energy saving rate of variable frequency pumps is 53.18%, the energy saving rate of the heat pumps unit is-12.91%, the total energy saving rate of the system is 9.00%, and the annual performance coefficient of the system is 3.86, and the overall energy saving effect is remarkable.
