Project Overview:
The project is located in Jincheng City, Shanxi Province, with a heating area of about 30,000 m2. The project is a non-energy-saving building and is distributed in mountainous areas. The climate is harsh. The air source heat pump is used to replace the coal-fired boiler heating. It was officially put into use in 2017 and continues to use the old radiator. Under the premise, the whole heating season, stable, reliable and efficient operation, according to the annual consumption of raw coal commonly used by users, can save about 680 tons of raw coal, reduce SO2 by about 11.6 tons, reduce CO2 by about 1,223 tons, reduce ash and slag emissions. 204 tons.

Know-how 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:
he 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.
