Cold Climates Residential Heating And Cooling Units , Central
Heating System
Residential Heating And Cooling Units features:
1, efficient
◆ The unit adopts a special pump for heat pump type, which matches
the high-efficiency condenser with the evaporator and the inlet
expansion valve. The four components are perfectly matched.
2, reliable operation
◆ The unit has 7 kinds of safety protection measures to ensure the
normal operation of the unit.
◆ The unit is designed for double circuit and double compressor.
When a single compressor fails, the other compressor can still
operate normally without affecting the customer's use.
◆ All units are tested by the national safety inspection system
before leaving the factory to ensure that the unit performance
meets national standards.
Project Brief
| Project location | Jinan , Shandong province |
| Total Building area | 21900M2 |
| Quantity of air-source heat pump | 21 sets |
| Model | SDNA-075Y(25HP) |
| System design | ultra low temperature air source heat pump+radiator heating |
Project Overview:
This is one of our many community heating projects. The building
area of this community is 36,500 m2 and the heating area is 2,1900
m2. The buildings are energy-efficient buildings. They have been
put into use in 2015, stable, reliable and efficient operation. The
average indoor temperature is around 20 °C. The area consumes about
28 KWH of electricity. According to the calculation of raw coal
commonly used by users, the annual savings of raw coal can be about
484 tons, SO2 is reduced by about 8.3 tons, CO2 is reduced by about
870 tons, and ash and slag emissions are reduced by about 145 tons.

Yushen Products Core Advantages
- Yushen air source heat pump is 35% more powerful than other
products, long heating time and less defrosting time
- It could work in extreme environment /Suitable for environmental
temperature:-25℃ to +45 ℃ /-13℉ to 113 ℉
- No capacity decay under low temperature, keep high COP in winter
Knowlege of Air Source Heat Pump
When properly installed, anair-source heat pump can deliver
one-and-a-half tothree times more heat energy to a home than
theelectrical energy it consumes. This is possible becausea heat
pump moves heat rather than converting it from fuel like combustion
heating systems do.

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.
