Case 28: Large-Scale Public & Commercial Project (Hospitals, Schools, Commercial Complexes)

Project Objective: Demonstrate heavy engineering execution and capacity.
Building Area: 3,000 m2
Climate Conditions: Tibetan plateau region at an altitude of 3,850m, long and severe winters, minimum temperatures dropping to −12℃, wide diurnal variations, and a 5-month heating season.
Project Requirements: Centralized winter space heating for teaching buildings and dormitories.

Solution & Performance:

Core Equipment: Configured with a 50HP ultra-low temperature air source heat pump host supported by a plate heat exchanger for centralized heating, driving over 200 sets of radiator terminals.

Performance & Effects: Zoned individual room controls manage classrooms at 18℃–20℃ and dormitories at 20℃–22℃ with radiator supply temperatures at 50℃–55℃. The system automatically adjusts output based on outdoor metrics, features powerful defrosting for alpine climates, and supports unattended remote monitoring. Compared to conventional coal-fired boilers, it achieves zero pollutant emissions, cuts energy consumption by 27%, and ensures reliable, low-maintenance institutional heating.
