The Need: Gushi Olympic Park is located in the southwest of the intersection of Yihe Avenue and Xinsi Street. The total planned area of the park is 1199.7 acres, with a total construction area of about 80000 square meters and a total investment of about 500 million yuan. As a large-scale cultural and sports landmark that integrates events, culture, and leisure, it is imperative to construct an air conditioning system in Gushi Olympic Park. Equipped with advanced air conditioning systems, it can not only create a comfortable indoor environment through precise temperature control and efficient ventilation, but also ensure that the venue is open 24/7, improve the utilization rate of public facilities, and truly serve the public.
The Challenge:
★During the competition, the audience suddenly rushes in, causing a sudden increase in personnel heat and moisture dissipation. Additionally, changes in audience activity levels (such as cheering and sitting) during the competition can lead to load fluctuations of up to 30% -50%; The load during non event periods has significantly decreased.
★Indoor sports stadiums belong to tall spaces and require machines to provide long-distance air supply.
Configuration:
★The air conditioning system adopts the Daikin VRV-X7 series+Nanjing Tianjia Rooftop Machine
★Scenario division of labor: The rooftop machine is responsible for large space ventilation and high load areas, while the VRV is responsible for fine temperature control areas.
★The DC variable frequency compressor of DAIKIN VRV-X7 series is used with the intelligent load forecasting system to adjust the output of cold and heat sources in advance to achieve “energy supply on demand”, and the response time is ≤ 10 minutes when the load fluctuates.
★The combination of the variable frequency flexibility of the Daikin VRV-X7 series and the high efficiency and stability of the Nanjing Tianjia rooftop machine can play a synergistic advantage in zone temperature control, energy conservation and consumption reduction.
