Project Brief
| Project location | Jinan , Shandong province |
| Total Building area | 65000M2 |
| Quantity of air-source heat pump | 39 sets |
| Model | SDNA-075Y(25HP) |
| System design | ultra low temperature air source heat pump+floor heating coil |
Project Overview:
The project is located at the intersection of Erhuan South Road and
Sunshine Road, Shizhong District, Jinan City, Shandong Province.
The total building area is about 65,000 m2, which is
energy-efficient building. The entire heat station is running well
and stable after it was successfully built and put into use before
the heating season in 2015. The average room temperature reaches
above 22 °C, and the average power consumption per unit area in the
heating season is about 25 KWH. According to the calculation of the
raw coal generally burned by each user, about 1086 tons of raw coal
can be saved, the SO2 is reduced by 18.4 tons, and the CO2 is
reduced by about 1950 tons. , reducing ash and slag emissions by
about 318 tons.

Knowlege of Air Source Heat Pump
Air source heat pumps (also known as ASHPs) are energy-efficient
alternatives to furnaces and air conditioners. They provide
efficient heating and cooling for your home all from one source.
In the summer, they cool your home and in the winter, they supply
heat. They do this by using electricity to transfer energy between
indoor and outdoor air:
| Items | Air source heat pump | Air conditioner unit |
| When heating | 40% energy saving than Ac | --- |
| When cooling | Equal energy consumption | Equal |
| Installation | Easy | easy |
| Maintenance | Little | some |
| Suitable for Ender | AC fans, under floor,radiator | AC fans only |
| Extra | Hot water | no |
The benefits of ASHPs include:
Energy efficient: ASHPs deliver one to three times more energy than the electricity
they consume.
Versatile (all year long) : ASHPs can heat your home in the winter and cool your home in the
summer.
Energy effective: ASHP can help lower your fuel bills, especially if you are
replacing older, inefficient heating and cooling systems.
Easy: ASHP are easy to install and require little maintenance.
