Wuxi buys low-voltage distribution cabinets; Kaifa box-type power transformer recycling. Advanced technology of air conditioning units: a combination of two-stage centrifugal compressors and spray-type evaporators. This design allows the machine to maintain a high energy efficiency ratio during part load and to operate stably in complex environments with significant load variations, greatly enhancing the stability and reliability of the unit. Features: high two-stage compression efficiency ratio. Operating range is much greater than that of single-stage compression, less prone to surge. High refrigeration efficiency; minimal efficiency decline during load reduction. Reduces the speed of the compressor impeller and bearing wear. Consequently, it extends the operational life of the unit. Avoids surge issues in the compressor at low load conditions. Second: The spray-type evaporator has significantly higher energy efficiency ratio and maintenance performance than the flooded evaporator, and the R134a charge is relatively less. The refrigerant entering the evaporator is sprayed downward from the top of the heat exchanger tube array. The liquid refrigerant forms a film on the tube wall and flows downward. The refrigerant circulation pump is used as the throttling device for the economizer evaporator, while simultaneously extracting and recycling the liquid refrigerant from the bottom of the evaporator to increase the refrigerant supply above the tube array, ensuring all copper tubes are covered by the liquid refrigerant. The unit does not require leveling adjustments; general positioning is sufficient for the evaporator to function normally. No major maintenance is needed; only water system cleaning is required, keeping maintenance costs low. Electric refrigeration has a history of over a century, with mature technology and manufacturing processes, easy to use and maintain, and has become a popular product with many users. The average life of a centrifugal compressor is 80,000 hours, and the unit is pre-filled with Freon and oil. The user can simply connect electricity and water on-site for operation.

Dense insulation busway (CMC). It has poor moisture-proof and heat dissipation effects. In terms of moisture-proof, the busbars are prone to dampness and water seepage during construction, leading to a decrease in inter-phase insulation resistance. The heat dissipation of the busbars mainly relies on the housing, as the wires are tightly arranged and installed, causing the heat from phases L2 and L3 to dissipate slowly, resulting in a higher temperature rise in the busway. Due to the limitations of the housing material, the dense insulation busway can only produce horizontal sections not exceeding 3 meters. Because of the small air gap between busbars, when the busbars carry high currents, a strong electromagnetic force is generated, leading to a superimposed state of magnetic oscillation frequency, causing excessive noise.
