Analysis of Winter Operating Condition of Ground Source Heat Pump System in a Residential District of Qingdao

Aiming at the problem of increasing energy consumption of winter heating in northern china, a new heating system- ground source pump system has been put forward for heating. Take a residential district of Qingdao for example, analyzing and comparing dynamic characteristic of each parameter of winter start-up stage and quasi-steady-state stage of ground source heat pump, measures and ideas for reducing operating energy consumption were proposed, the results provide basic data for the operation and extension of the ground source heat pump air-conditioning of Qingdao area.
