The Need:Zhengzhou Electric Power Vocational and Technical College (Xiangfu District) is located at G230 Kaigang Avenue, Xiangfu District, Kaifeng City, Henan Province. Currently, it is planning to install hot water systems in student dormitories and public areas to provide more convenient and comfortable living conditions for teachers and students, and further improve the quality of campus services.
The Challenge:
★Users have high requirements for comfort: the stability of hot water temperature is strictly required, and fluctuations in water temperature can easily lead to student complaints.
★Difficulty in balancing water supply pressure: There is a large difference in water pressure between high-rise and low rise dormitories, and improper design may result in low water output from high-rise buildings and rapid water flow from low rise buildings.
Configuration:
1# Dormitory: 1,000 solar collectors + 2 sets of 10HP air-source heat pumps + 25-ton water tanks
2# Dormitory: 1,000 solar collectors + 2 sets of 10HP air-source heat pumps + 25-ton water tanks
9# Dormitory: 1,000 solar collectors + 2 sets of 25HP air-source heat pumps + 50-ton water tanks
10# Dormitory: 1,000 solar collectors + 2 sets of 25HP air-source heat pumps + 50-ton water tanks
13# Dormitory: 1,000 solar collectors + 2 sets of 25HP air-source heat pumps + 50-ton water tanks
15# Dormitory: 1,000 solar collectors + 2 sets of 25HP air-source heat pumps + 50-ton water tanks
18# Dormitory: 1,000 solar collectors + 2 sets of 25HP air-source heat pumps + 50-ton water tanks
20# Dormitory: 1,000 solar collectors + 2 sets of 25HP air-source heat pumps + 50-ton water tanks
★Adopting a “return water circulation system”, a circulation pump is installed in the main pipeline to maintain continuous flow of hot water in the pipeline, ensuring that hot water is discharged within 3-5 seconds after turning on the faucet. .
★A temperature sensor is installed at the end of the pipeline to monitor the temperature of the pipeline and dynamically adjust the output of hot water.
★And install a hydraulic balance valve on the system to avoid water pressure fluctuations when the dormitory building uses water simultaneously.
