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.

Yushen Products Core Advantages
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.
Comparasion to common AC unit
| Items | Air source heat pump | Air conditioner unit |
| When heating | 40% energy saving than Ac | --- |
| When cooling | Equal energy consumption | Equal |
| Installation | Easy | easy |
| Maintenance | Little | some |
| Suitable for Ender | AC fans, under floor,radiator | AC fans only |
| Extra | Hot water | no |
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.
