Ultra Cold Climate High COP Air Source Heat Pump Heating System
What is 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.

Project Overview:
The project is located in Wuhai City, Inner Mongolia, with a
heating area of about 70,000 m2. The project is mainly distributed
in Wuhai Energy Company, Daeyang Power Plant, coal mine, school,
town government, etc. The average outdoor temperature in Wuhai City
is -10 °C in January. The lowest -22 °C, officially put into use in
2017, the entire heating season, stable and reliable
high-efficiency operation, according to the average coal burned by
the users, the annual savings of raw coal can be about 1,650 tons,
reduce SO2 by about 28 tons, reduce CO2 by about 2,967 tons, Reduce
ash and slag emissions by approximately 494 tons.
