Company Office Building Heating System Air Source Heap Pump 15 sets 25HP
Project Overview
Location: E 121 N 39
Heating area: 14000M2
Air source heat pump features
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.
Yushen product Advantages
l Jet Boost compressor, high efficient and environmental-friendly, even in -25C can work in high COP
l 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.
l 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
l 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.
l 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
