What are the characteristics of DONPER Compressor's product structure?

Combining the previously mentioned product series layout with details such as core component design and technical compatibility, DONPER Compressor's product structure exhibits distinct characteristics: comprehensive series coverage, ingenious core component design, and adaptability to diverse eco-friendly scenarios. Specific features are as follows:

Extensive Series and Complete Specifications Covering All Refrigeration Scenarios

DONPER Compressor offers 15 major series with over 400 varieties, spanning a wide power range to meet demands across all scenarios from residential to commercial and specialty refrigeration. For residential applications, low-power series like D, S, and W serve compact refrigeration units, while the L series caters to standard refrigerators and freezers. Commercial offerings include specialized series for display cabinets and ice cream machines. In specialty fields, the cryogenic compressor series achieves cooling from -40°C to -200°C, breaking previous reliance on imported solutions. Additionally, the company offers variable-frequency series like the VFLN and Q series, along with rotary variable-frequency compressors for air conditioning systems. This creates a comprehensive product matrix that complements traditional and high-end solutions, as well as fixed-frequency and variable-frequency technologies.

Innovative Core Component Design Enhances Performance and Stability

DONPER has achieved multiple breakthroughs in compressor core component structures. For instance, deep-cold compressors employ a double-suction, double-discharge valve assembly structure. Compared to the single-suction, single-discharge structure of conventional compressors, this significantly enhances suction and discharge efficiency, resolving insufficient refrigeration capacity issues in deep-cold applications. The L series incorporates special structural components such as high-strength small-diameter crankshafts and flat thrust bearings, paired with a design featuring four compression springs supporting the core assembly to reduce vibration transmission. Patented structures like the separated insulated exhaust silencer chamber further reduce noise levels to as low as 25 dB(A) in certain models, with the L58CZ1 achieving below 36 dB(A)—significantly outperforming industry standards. Additionally, select models replace conventional long-tube piping with flexible copper corrugated tubing and specialized connectors, eliminating welding requirements while improving refrigeration oil replacement efficiency.

Adapting to Environmental Requirements, Structural Compatibility with New Refrigerants

The product structures are universally compatible with environmentally friendly refrigerants, aligning with the “dual carbon” strategy. For instance, the residential D65CY1 model uses the eco-friendly R600A refrigerant, while commercial and high-end series are advancing the development of compressors utilizing environmentally friendly refrigerants like R290 and R1234yf. Compared to traditional refrigerants, these not only offer greater environmental benefits but also reduce power consumption. Simultaneously, to match the operational characteristics of eco-friendly refrigerants, the products feature optimized sealing and heat dissipation structures. For instance, the D65CY1 model incorporates metal heat dissipation fins, ensuring both the cooling efficiency of eco-friendly refrigerants and resolving heat dissipation challenges associated with their use.

Balancing Miniaturization and Modularity to Meet Diverse Installation Needs

Residential models prioritize compact, lightweight designs. The D65CY1, for instance, measures approximately 180×120×170mm and weighs just 9.5kg, offering a compact structure ideal for limited installation spaces in small-to-medium refrigeration equipment. The L-series products also feature lightweight, compact dimensions, facilitating easy integration into household refrigerators. Commercial and specialty models incorporate modularity, allowing core components to be reconfigured for varying refrigeration requirements. Additionally, some models utilize standardized interface designs, streamlining both new equipment installations and retrofits for older units.
