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. ?url=http%3A%2F%2Fdingyue.ws.126.net%2F2024%2F0408%2F71b3a41bj00sbm3qz007cd000z800nim.jpg&thumbnail=660x2147483647&quality=80&type=jpg 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%. ?url=http%3A%2F%2Fdingyue.ws.126.net%2F2024%2F0408%2F25e5abf2j00sbm3qz003fd000z800nim.jpg&thumbnail=660x2147483647&quality=80&type=jpg
