Commissioning and operational issues in a super-low-energy building ground source heat pump in summer operation analysis <br><br>[Abstract] Taking a ultra-low power demonstration building as an example, the combined data demonstrate building ground source heat pump system runs in summer, and analyzes the ground source heat pump system for return water temperature difference between large and small COP value of the unit of the problem and propose solutions; based on operational data accumulated during testing refrigeration is about 54650.8kW · h; pre-ground source heat pump for the return water temperature is about 15 oC, COP values the unit at 2.5 ~ between 3.75, the return water temperature in the solution for about 2 ~ 4 oC, COP value between 4.0 and 5.0 units. Through this running test analysis, to provide reference for the rational operation of ground source heat pump ultra-low energy consumption buildings. <br>[Keywords] ultra-low power architecture; ground source heat pump; energy consumption; COP value; Analysis

Analysis of the commissioning and operation of the summer operation of the ground source heat pump of an ultra-low energy-consuming building<br><br>Taking an ultra-low energy consumption demonstration building as an example, combined with the data of the summer operation of the ground source heat pump system of the demonstration building, the problem of large water temperature difference and small COP value of the unit was analyzed and the solution proposed; .8kW.h; the temperature difference of the pre-ground source heat pump for return water is about 15 oC, the UNIT COP value is between 2.5 and 3.75, the temperature difference for the return water after the solution is about 2 to 4 oC, the unit COP value is 4.0 Between -5.0. Through this running test analysis, it provides reference for the reasonable operation of ground-source heat pump in ultra-low energy-consuming buildings. <br>Ultra-low energy-consuming buildings; ground source heat pumps; Energy consumption; COP value; problem analysis

Commissioning and operation analysis of ground source heat pump in summer<br>[Abstract] taking an ultra-low energy consumption demonstration building as an example, combined with the data of ground source heat pump system operation in summer, this paper analyzes the problems of large water temperature difference between the supply and return of ground source heat pump system and small COP value of the unit, and puts forward solutions; according to the operation data, the cumulative cooling capacity during the test period is about 54650.8kw · h; the water temperature difference between the supply and return of ground source heat pump in the early stage is 15 At about OC, the COP value of the unit is between 2.5 and 3.75, the temperature difference between the supply and return water is about 2 to 4 OC after the solution, and the COP value of the unit is between 4.0 and 5.0. Through the test and analysis of this operation, it can provide reference for the reasonable operation of ground source heat pump in ultra-low energy consumption buildings.<br>[Key words] ultra low energy consumption building; ground source heat pump; energy consumption; COP value; problem analysis
