Cold Climate Air source Heat Pump Suitable for AC fans / Underfloor
Coil / Radiators
Features
- ASHPs could reduce household energy consumption by up to 40%,
compared to electricity heating and fuel oil heating.
- ASHP systems can be installed in different types of housing across
a range of climates
- Cold climate ASHPs are capable of delivering heating in extremely cold regions, such as
New England and the upper Midwest
- Quiet design, beautiful appearance, low noise, large blade axial
flow fan, reasonable and compact system piping design, avoiding
large vibration and resonance, using V-shaped fin structure, high
space utilization, uniform air supply on finned tube, unit The
shape is smoother.
- Fully automatic intelligent control, no need for special management
- The unit is quick and easy to install and is not subject to
installation restrictions.
Yushen air source heat pump
- 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.
- It adopts 9.52*0.35 internal thread high-efficiency heat exchange
copper tube and 3.1mm large-format hydrophilic aluminum fins with
better hydrophobicity; it improves the operating efficiency during
frosting and reduces the number of defrosting.The optimized long
flow path design and wide expansion of the expansion throttle
ensure uniform distribution of refrigerant in low temperature
environments. Ensure even frosting, complete defrosting, strong
heating and efficient operation
