Xigaze Dongga Project Department Solar + Air Source Heat Pump Hybrid System

Project Objective: Showcase multi-energy complementary applications of solar thermal + air source heat pumps for future clean energy utilization in high-altitude regions.

Building Area: Project camp facilities

Climate Conditions: Abundant solar insulation resources in Xigaze, low winter temperatures, and wide diurnal variations.

Project Requirements: Satisfy camp space heating and domestic hot water needs by fully leveraging local solar resources to minimize overall electricity consumption.

Solution & Performance:

Implemented a multi-energy complementary scheme combining solar thermal collection with ultra-low temperature air source heat pumps. Configured with 20 sets of solar collector arrays + 15HP air source water heating units + a 10-ton large-capacity insulated hot water storage tank.

Operation Logic: During favorable sunlight conditions, the solar thermal system takes priority to handle the primary thermal load. On overcast days or during nighttime when sunlight is insufficient, the system automatically switches to engage the air source heat pump as an auxiliary heat source, ensuring uninterrupted thermal output.

This complementary architecture taps deep into local clean energy, curtails overall electrical draws, runs fully automatically without requiring manual supervision, and serves as a stellar demonstration project for comprehensive clean energy utilization in plateau regions.
