Commercial Use Air Source Heat Pump High Temperature Heating Unit
Features
1. Adopt Copeland ultra-low temperature compressor, stable
operation at -25 °C ultra-low temperature environment
2, the air source heat pump can be freely connected in parallel to
achieve large-scale residential central heating
3, the unit operates environmentally friendly, without any waste
gas exhaust
4. Connectec with underfloor heating coil has better performance
Yushen air source heat pump configuration
- 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
