Clean Energy Heating System Air Souce Heat Pump for Central Heating of Office
Project Introduction
Location: E 117 N 36.6
Floor quantity: 7
Building area: 12050M2
System design: ultra low temperature air source heat pump+radiator
Quantity of air-source heat pump: 9 set
The office building area of this project is 13,744 square meters and the heating area is 12050 square meters.
The building has 9 floors, the exterior wall has no insulation, and the windows have a single layer of glass.
The air source heat pump system was officially put into use in 2017, and the entire heating season is stable and reliable and efficient.
According to the coal heating calculation previously used by the user, it can save 287 tons of raw coal, reduce SO2 emissions by about 4.9 tons, reduce CO2 emissions by 516 tons per month, reduce coal ash, and discharge coal slag by about 86 tons.
Air source heat pump Information
- Air source heat pump is 40% energy-saving than that of electric AC unit in heating.
- high automation, easy operation
- Water circulate inside the system, safe and comfortable
- It could be connected with different enders, e.g. fan coil, radiator, floor heating, convenient and high-efficient
