发布时间：2021-11-23 - 摘要：This paper studies the application of ground source heat pump heating system in smart building. Through the installation of heating transmission and distribution system controller, the pressure loss in the system loop can be overcome, the zero pressure difference control point can be selected to control the throttling resistance loss of all heat users, and the heating system unit can be turned on in the smart building to realize the application of ground source heat pump heating system in the smart building. Through three times of experimental detection, the highest energy consumption of the system in 24-hour application is 15.35/kw. h, the lowest energy consumption is 12.91/kw. h, and the average energy consumption is 14.34/kw. h. In the application of intelligent building, the energy consumption is relatively stable, low energy consumption and good practicability.关键词：intelligent building;ground source heat pump;application research

发布时间：2021-11-23 - 摘要：The comprehensive stadium needs to take into account the different needs of competition and post-competition operation. If the air-conditioning system is designed in accordance with the international standards for competitions, there will be great redundancy after the change of activity types and frequencies during post-competition operation. Therefore, it is necessary to customize the operation strategy for the operation requirements. Aiming at a comprehensive gymnasium in Hangzhou, the hourly load simulation of the whole year is carried out according to the operation content after the competition, the results show that the peak load of the air conditioning system is significantly decreased by 30% compared with the original design, and the system load rate is lower than 40% in 90% of the whole year， which proves that the ice storage system has good economy. Based on the load prediction， the optimal operation strategy of ice storage air conditioning system under different load rates is analyzed， which provides a reference for the application of ice storage system in comprehensive gymnasium.关键词：gymnasium;ice storage air conditioning;load simulation;operation control strategy
