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.

Air source heat pump heating project Introduce

Project location	E 107 N 40 Climate:lowest -22C in winter
Heating area	70000M2
Quantity of air-source heat pump	55 sets
Model	SDNA-075Y(25HP)
System design	ultra low temperature air source heat pump+radiator
Control	Central heating station automatic control

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.

Yushen Products Advantages

Jet Boost compressor, high efficient and environmental-friendly, even in -25C can work in high COP
Fan of heat exchanger is big diameter Jagged type, which increase the air flow tangent length when air going through fans, reduce noise; When the air volume is increased, the heat exchanger is more evenly.
Multi-throttle channel design is accurate.Multiple energy-saving devices in a single system, precise control of refrigerant flow, enabling the unit to maximize heat/cooling capacity and maximum energy efficiency in various working environments, reducing operating costs
The water side shell and tube heat exchanger have high efficiency and reliability.The industry's leading refrigerant distribution technology can effectively improve the uniformity of gas-liquid two-phase fluid distribution into heat transfer tubes, improve the utilization of heat exchange tubes, and achieve efficient heat transfer.
Large-area hydrophilic aluminum heat exchangers increase the heat production.
The four-row tube V-shaped arrangement has high heat exchange efficiency and uniform wind speed distribution.
