1. Patented technology: The patented compressor parallel technology is used to automatically judge the number of compressors to be turned on according to the end demand and climatic conditions.

2, high temperature and high efficiency: low load conditions, less open compressor. The heat exchanger area is affluent and the overall efficiency of the unit is increased by 20%.

3, low temperature and high heat: high load conditions, the compressor is fully open. Make full use of the heat exchanger, the unit heat supply increased by 30%

4, PLC automatically balances the running time of the compressor, the compressor life is longer 5, the defrosting is rapid: the defrost compressor is fully open, more quickly. Recommended area: 1500～2000m2 for energy-saving building heating in Beijing-Tianjin-Hebei region

Applications

It is suitable for the cental heating of office building, hotel and residential community.
In winter it provide water of 50℃ for heating to the ender to produce heat.

Yushen Products Core Advantages

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.

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.
