[Abstract]:In recent years, with the rapid development of our economy, the process of urbanization continues to accelerate, building energy consumption is also increasing rapidly, China has gradually put forward higher requirements for building energy monitoring. The country has issued the "large-scale public building energy consumption monitoring system engineering technical specifications", "Renewable energy building application demonstration project data monitoring system technical guidelines" urged the national building energy consumption monitoring level to improve. In 2010, Chongqing has established the energy consumption monitoring platform of public buildings, covering 221 office buildings in Chongqing. In 2012, the Ministry of Housing and Urban-Rural Construction again issued the Circular on promoting the Construction of Renewable Energy Building Application data Monitoring system. The importance and urgency of establishing a monitoring platform for renewable energy application systems are emphasized. As a renewable energy technology application, ground source heat pump (GSHP) has the advantages of energy saving and environmental protection. In China, there is an unprecedented rapid development. This paper mainly focuses on the operation strategy of ground source heat pump system and the development of monitoring system in Chongqing area. Based on the climate characteristics of Chongqing area and the operation characteristics of all kinds of buildings, the dynamic load characteristics of office buildings in Chongqing area are simulated and analyzed in this paper, from the point of view of load accumulation. The unbalance between the accumulative heat load of air conditioning and the accumulative cooling load of air conditioning in office buildings and the unbalance between accumulative heat load and accumulated cooling load of underground tube heat exchanger are analyzed quantitatively. From the point of view of load dynamic change, the distribution law of air conditioning load rate in Chongqing office building and the load rate distribution law of underground tube heat exchanger are obtained. Based on the actual measurement of a ground source heat pump system in Chongqing and the actual operation of the ground source heat pump system, the energy saving performance of the ground source heat pump system is analyzed. Through the ground source heat pump system of office buildings measured in winter and summer, the distribution law of air conditioning load rate and the distribution law of underground pipe load rate of office buildings are obtained. The results are compared with the simulation results. In view of the different phenomena between the local source heat pump system and other low energy efficiency ground source heat pump systems in this area, the advantages of the control strategy are analyzed in combination with the control strategy of the system. According to the control strategy, the system monitoring strategy is put forward. Finally, the auxiliary monitoring strategy is put forward according to the bad phenomena in the system operation. By means of energy consumption simulation and engineering measurement, the distribution of air conditioning load in office buildings and the monitoring strategy of ground-source heat pump system are discussed in this paper. 1) according to the dynamic simulation results of energy consumption, from the point of view of the change of load intensity, the ground-source heat pump system used in office buildings in Chongqing has the longest running time of 25-50% of the design load. The main distribution range of the load rate of buried pipes in the whole year is 75 / 100. From the point of view of annual load accumulation, the ratio of cumulative cooling load to accumulated heat load of building air conditioning is 34/100. The ratio of accumulated heat gain to accumulated heat loss is 23 / 100. The measured analysis of ground source heat pump shows that the main distribution range of air conditioning load rate in office buildings is 50 / 75%. The main distribution range of underground pipe load rate in the whole year is 50 ~ 755.At the same time, the air conditioning load and buried pipe load of building not only change dynamically in different seasons of the whole year. And it is dynamic at different times of the day. 2) in view of the dynamic change of air conditioning load and buried pipe load in building, the monitoring objects of ground source heat pump monitoring strategy are water temperature, flow rate, inlet and outlet pressure of water pump on user side and power consumption of water pump. Return water temperature, flow rate and geotechnical temperature on the side of buried pipe.
