1. High Energy Efficiency, Cost Reduction and Policy Compliance
Adopting a DC brushless inverter motor, it boasts outstanding energy-saving performance and policy adaptability, with specific advantages including:
-
Energy efficiency improvement: Compared with traditional models, the energy efficiency is increased by more than 15%, and the COP value exceeds 4.5, achieving efficient energy conversion.
-
Policy compliance: Easily meets the energy efficiency requirements of Level 2 and above in the new national standard GB 21455-2023, conforming to the national energy-saving and emission-reduction orientation.
-
Cost reduction effect: Taking a 24/7 operating vending machine as an example, equipping this compressor can save nearly 300 kWh of electricity annually, significantly reducing long-term operating costs for merchants.

2. Stable and Durable, Adapting to Complex Working Conditions
With sophisticated manufacturing technology, it performs excellently in stability and durability, adapting to various complex working conditions:
-
Long service life: Supports 24/7 continuous operation, with a service life of up to 80,000 hours, far exceeding the industry average.
-
Low failure rate: The fault repair rate is only 1.2%, which is much lower than the industry average of 5%, reducing maintenance costs.
-
Low noise and wear resistance: The scroll structure design effectively reduces operating noise to ≤3-5 DBA, minimizes component wear, and is suitable for scenarios with frequent start-stop.
3. Environmental Compatibility, Following the Dual Carbon Trend
It has excellent environmental compatibility, closely following the global dual carbon trend, and has strong refrigerant adaptability:
-
Wide refrigerant compatibility: Fully compatible with mainstream environmentally friendly refrigerants such as R32 and R410A, meeting diverse application needs.
-
Green and low-carbon: The R290 model achieves zero Ozone Depletion Potential (ODP) and ultra-low Global Warming Potential (GWP), in line with the dual carbon strategy.
-
Breaking low-temperature limitations: Dedicated models for low-temperature scenarios are compatible with R404 refrigerant, with a minimum evaporation temperature of -42°C, solving the problem that scroll compressors are not suitable for low-temperature applications.
4. Diverse Scenarios, High Market Recognition
It has strong scenario adaptability and high market recognition, with remarkable performance in both domestic and foreign markets:
-
Diverse application scenarios: Widely used in household air conditioners, vending machines, small agricultural product cold storage and other fields.
-
High domestic adoption rate: 35% of vending terminals nationwide and most small cold storage below 50 m³ are equipped with its products.
-
Stable market performance: In 2024, its domestic market share remained stable, export volume increased by 24.78% year-on-year, and overseas recognition continued to rise.
