The benefits of ASHPs include:

• Ultra-energy-saving products: Input 1 degree of electricity can output 3-4 degrees of heating energy.
• High safety performance: water and electricity is isolation, no open flame, no leakage, and ensure personal safety, so it is the safest product.
• Long service life and low cost: Under normal conditions of use, the floor heating coil's life can reach 50 years, and other heating systems have an average service life of 10-20 years, which greatly saves system investment costs.
• Low-temperature heating: low-temperature heating technology is significantly improved, the system can run at -25 °C by thermal energy, low-temperature environment energy efficiency reaches the highest in the industry, is the best product to replace heating fuel boilers.

Yushen air source heat pump confgurations

• The water side shell and tube heat exchanger has 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.
• Multi- 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
• 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.
• Large-area hydrophilic aluminum heat exchangers increase the heat production..

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

Working principle

heat exchanger through the air side (evaporator), absorption air inexhaustible low grade heat, while using the compressor work into high grade heat release to the hot water side heat exchanger (condenser), resulting in high temperature water. Water goes into the underfloor coil and heat the rooms.
