Project Overview
This project delivers a commercial heating solution for an 8,000 sqm office building. The system features 2 sets of 170kW air to water heat pumps paired with a 45kW PV solar system, creating a highly efficient and sustainable clean energy heating system.
Climate & Environmental Conditions
The project is located in a temperate continental climate zone with cold, dry winters. Winter temperatures frequently drop below freezing, placing high demands on the heating capacity and low ambient temperature performance of the heat pump system. The region benefits from abundant sunshine hours, making it ideal for solar-assisted heat pump integration.
System Specifications
| Parameter | Details |
|---|---|
| Heat Pump Type | 170kW Commercial Air to Water Heat Pump (Heating & Cooling) |
| Quantity | 2 units |
| Terminal Equipment | Fan Coil Units (FCU) |
| Hot Water Supply Temp | 45ยฐC |
| Indoor Design Temp | 24ยฐC |
| Solar System | 45kW On-grid Photovoltaic System |
Key Features & Benefits
1. High-Efficiency Air Source Heat Pump Technology
Our commercial air source heat pump units deliver reliable heating performance even in low ambient temperatures. Compared to traditional gas boilers or electric heaters, this air to water heat pump technology significantly reduces energy consumption and carbon emissions โ a smart choice for eco-friendly building heating.
2. Solar-Assisted Heat Pump System (SAHP)
The integration of a 45kW PV system with the heat pump heating system enables daytime solar power to directly drive heat pump operation. This solar heat pump configuration achieves “self-consumption” mode, dramatically cutting electricity costs and maximizing the ROI of renewable energy systems.
3. Comfortable & Stable Indoor Climate
The fan coil unit (FCU) terminal system circulates 45ยฐC hot water to maintain a consistent 24ยฐC room temperature, ensuring a warm and productive workspace throughout the heating season.
Why This Solution Works
| Challenge | Our Solution |
|---|---|
| High winter heating demand | High-capacity commercial heat pump (340kW total) |
| Rising energy costs | Solar PV + heat pump hybrid for cost savings |
| Environmental compliance | Zero on-site emissions, green building heating |
| Large floor area coverage | Modular industrial heat pump design |
Application Value
This case demonstrates the reliability and cost-effectiveness of air source heat pumps for commercial buildings in cold climate regions. The PV-assisted heat pump model not only reduces operational energy costs but also supports sustainable building design and net-zero energy building goals โ offering a replicable HVAC solution for offices, hotels, schools, and similar commercial facilities worldwide.
