On April 8, 2024, GMCC Midea and Welling, core suppliers of system-level solutions for consumer electronics, showcased a range of core components including compressors, motors, chips, valves, and system-level solutions for household refrigeration, heating, commercial refrigeration, heating, and mobile refrigeration at the 2024 China Refrigeration Expo. They also made a significant announcement, introducing three new products: integrated variable frequency rotary compressors, commercial miniaturized high-efficiency variable frequency scroll compressors, and ultra-quiet heat pump heating compressors. These innovations, powered by cutting-edge technology at their core, aim to enhance the overall performance of cooling and heating terminal products towards miniaturization, high energy efficiency, ultra-quiet operation, and green environmental protection.
GMCC Meizhi and Welling Welling Make Their Debut at the 2024 China Refrigeration Exhibition
Innovating across the board, Meizhi introduces three new compressors leading industry development
Meizhi’s integrated variable-frequency rotary compressor features a revolutionary integrated liquid storage structure placed at the bottom, ensuring high efficiency and energy savings while achieving extreme miniaturization. The product's width is reduced by 20% compared to mainstream industry products, effectively increasing air conditioning cabinet capacity by 25%; it utilizes refrigerant insulation technology to improve the Coefficient of Performance (COP) by 3%, and the heating/cooling capacity of air conditioners by an additional 2% to 3%; simultaneously, it employs gas-liquid two-phase control technology to reduce suction pressure loss by 50%, enhancing efficiency and energy savings; and with the counter-gravity oil return technology, it increases reliability, allowing for continuous operation for up to 3500 hours under extreme conditions. This product has achieved up to 97 patent outcomes, endowing home air conditioning products with compactness and efficiency through its highly original miniaturized integrated advantages.
Meizhi's ultra-quiet heat pump heating compressor fully meets the global sustainable backdrop’s demand for green, low-carbon heat pump heating. With its pioneering ultra-high solid frequency welding support frame, improved shaft system balance coefficient, cavity resonance shift technology, and optimized fundamental wave electromagnetic force of the motor, it achieves a reduction in noise amplitude within the core frequency range. For the challenge of operating in low-temperature environments, Meizhi's ultra-quiet heat pump heating compressor uses a wide operating range design and high-reliability bearing technology to achieve outstanding heating performance at ultra-low ambient temperatures of -35℃, meeting the requirements for a 75℃ water output temperature in low ambient temperatures, with a maximum condensation temperature of 83℃, and a maximum compression ratio of 17.
Meizhi's commercial miniaturized high-efficiency variable frequency scroll compressor breaks through the industry status quo with its "small shell diameter, big heart, super core" advantages, achieving first-level energy efficiency in multi-split air conditioning systems, full-spectrum quietness, and flexible layout. Compared to the previous generation of variable frequency scroll products, this new product reduces volume by 28% and increases unit capacity weight by 27.6%; it uses an efficient adaptive asymmetric structure, improving the COP by 4.2% (60rps) compared to industry products of the same capacity, reducing OCR by 25% (120rps), and increasing motor and mechanical efficiency by 2%; its full-spectrum active noise reduction design keeps operational noise below 59 decibels; at the same time, it eliminates enthalpy pressure pulsation and backflow from the source, enhancing the entire product chain's reliability, and allowing pipeline operation stress to increase by 240%.
GMCC Unveils Three New Compressors at the 2024 China Refrigeration Exhibition
Efficient and Low-Noise, Midea and Highly's System-Level Heating and Cooling Solutions Enhance Comfortable Living
In line with the HVAC industry's move towards high-end, smart, and green upgrades, Midea and Highly showcased a variety of core products and solutions at this refrigeration exhibition, catering to residential heating and cooling, commercial heating and cooling, and mobile refrigeration scenarios. Among them, four products were honored with the "Innovative Product" award at this year's China Refrigeration Exhibition.
GMCC and Welling Showcase Comprehensive Heating and Cooling Solutions
In the commercial air conditioning sector, GMCC's 12-16HP multi-connect variable frequency rotary compressor, alongside the newly launched ultra-quiet heat pump heating compressor, has clinched this prestigious recognition. Achieving a powerful output with speeds up to 140Hz, these innovations combine high efficiency and low noise benefits, empowering commercial air conditioners with robust and rapid cooling capabilities. In the realm of mobile refrigeration, GMCC's vehicular miniature DC variable frequency compressor excels with its extremely low noise, compact size, and high reliability, making it ideal for use in vehicle refrigerators, RV fridges, medical cool boxes, and portable containers among other mobile vehicular scenarios. In the domain of motors and pumps, Welling has injected vigorous power into air conditioning and heat pumps with an upgraded range of motors and pump technologies. Welling's green, high-quality, thin, and lightweight permanent magnet motors enhance material utilization through slim, lightweight technology. Additionally, by employing noise reduction techniques to lower operational sound, and a suite of reliability technologies to ensure steady and dependable performance, these motors have been acknowledged with the "Innovative Product" award for their outstanding capabilities.
Adhering to the philosophy of "Technology Drives Everything," GMCC and Welling deeply understand the needs and shifts within the HVACR market. Through their relentless pursuit of core technological innovations, groundbreaking products, and lean manufacturing levels, they aim to provide end users with a comfortable, convenient living and working experience. Looking to the future, GMCC and Welling are poised to take on the role of industry leaders, continuously contributing to the green, efficient, and intelligent evolution of the global HVACR industry.
