Driven by the wave of new energy vehicles and intelligence, air-conditioning capacitors (Aircon Capacitor), as the core components of the refrigeration system, are undergoing a full range of technological iterations from material innovation to intelligent control.
Taking YMIN capacitors as an example, its technological innovation and performance breakthroughs in new energy vehicle refrigerators also provide inspiration for the efficient operation of air-conditioning systems and redefine the energy efficiency standards and reliability boundaries of refrigeration equipment.
Two-way breakthroughs in low-temperature start-up and high-temperature tolerance
Traditional air-conditioning capacitors are prone to capacitance decay or overheating failure at extreme temperatures, while the **liquid chip aluminum electrolytic capacitor** developed by YMIN can stably output instantaneous large current in a -40℃ environment through low-temperature capacitance decay suppression technology, solving the problem of cold start of the compressor.
At the same time, the composite dielectric layer and solid electrolyte used by the capacitor keep the capacitance value stable at a high temperature of 105℃, significantly extending the service life of the vehicle air-conditioning compressor. This two-way temperature resistance enables the air-conditioning system to adapt to complex working conditions from extreme cold to hot summer.
Co-optimization of high load and dynamic response
New energy air conditioning systems need to cope with frequent start-stop and dynamic load changes. YMIN’s polymer hybrid capacitors reduce energy loss by 30% through low ESR (equivalent series resistance) design, and combined with the characteristics of high ripple current (>5A), reduce voltage fluctuations when the compressor is running at high frequency, avoiding the decrease in refrigeration efficiency caused by current shock. For example, in vehicle air conditioning compressors, such capacitors can withstand long-term high-load operation, and the failure rate is reduced by more than 50% compared with traditional products.
Intelligent integration and energy efficiency revolution
Modern air conditioning systems deeply integrate capacitors with electronic control units (ECUs) to achieve dynamic power regulation. When the sensor detects that the compressor is overloaded, the ECU can intelligently distribute the capacitor output, prioritize the operation of core components, and optimize the power utilization rate through ripple suppression algorithms. Studies have shown that the comprehensive energy efficiency of air conditioning systems equipped with YMIN capacitors is improved by 15%-20%, especially for new energy vehicles on high-voltage platforms.
Domestic substitution and industrial upgrading
YMIN capacitors have replaced Nichicon and other international brands in batches with their high voltage resistance (450V) and long life (>8000 hours), achieving domestic breakthroughs in the field of vehicle air conditioning. Its technical path not only promotes the development of air conditioning systems towards miniaturization and oil-free, but also realizes remote monitoring of the health status of capacitors through Internet of Things technology, providing data support for predictive maintenance.
Conclusion
Air conditioning capacitors are evolving from “functional components” to “smart energy hubs”. YMIN’s technical practice shows that the dual breakthroughs of material innovation and system integration can not only solve the pain points of refrigeration in new energy scenarios, but also set a benchmark for low-carbon and high-reliability thermal management ecology. In the future, with the integration of solid-state electrolytes and wide-bandgap semiconductor technologies, capacitors will release greater potential in the energy efficiency revolution.
