Comprehensive innovation , three new compressors from Midea lead the industry development

GM Integrated variable frequency rotor compressor The industry-disruptive integrated liquid reservoir bottom structure is adopted to ensure high efficiency and energy saving while achieving extreme miniaturization. The product width is reduced by 20% compared with the mainstream products in the industry, effectively increasing the air conditioning cabinet capacity by 25%; the refrigerant insulation technology is used to increase the COP by 3%, and the air conditioning heating/cooling capacity is further increased by 2%~3%; at the same time, the gas-liquid two-phase control technology is used to reduce the suction pressure loss by 50%, which is more efficient and energy-saving; and the reverse gravity oil return technology is used to improve reliability, and it can run continuously for 3,500 hours under extreme working conditions. This product has obtained up to 97 patent results, and its original small integrated advantages enable the compactness and efficiency of household air conditioning products.

GM Ultra-quiet heat pump heating compressor Fully meet the green and low-carbon heat pump heating needs under the global sustainable background. With the four key technologies of ultra-high fixed frequency welding bracket, shaft balance coefficient improvement, cavity resonance frequency shifting technology, and motor fundamental electromagnetic force optimization technology, the noise amplitude of the core frequency band is reduced; for the operation problem in low temperature environment, GM's ultra-quiet heat pump heating compressor achieves excellent heating performance at ultra-low ambient temperature of -35℃ with ultra-wide operating range design and high-reliability bearing technology, which can meet the 75℃ outlet water temperature requirement at low ambient temperature, and the maximum condensing temperature reaches 83℃, and the maximum compression ratio reaches 17.

GM Commercial small-sized high-efficiency variable frequency scroll compressor With the advantages of "small shell diameter, large heart, super energy core", it breaks through the current status of the industry and achieves first-class energy efficiency, full-band quietness and flexible layout of multi-split air-conditioning systems. Compared with the previous generation of variable frequency scroll products, this new product has a 28% reduction in volume and a 27.6% increase in unit capacity weight; the use of a high-efficiency adaptive asymmetric structure increases COP by 4.2% (60rps) and OCR by 25% (120rps) compared to products with the same capacity in the industry, and increases motor and mechanical efficiency by 2%; the full-band active noise reduction design controls the operating noise within 59 decibels; at the same time, it eliminates enthalpy pressure pulsation and backflow from the source, improves the reliability of the entire product chain, and increases the allowable stress of pipeline operation by 240%.

GMCC Compressor New Product Launch Ceremony

GMCC presents three new compressor products at the 2024 China Refrigeration Exhibition

High efficiency , low noise, Meizhi, Welling System level Heating and cooling Solutions Empowerment Comfortable life

In line with the high-end, intelligent and green upgrade direction of the HVAC industry, Midea and Welling showcased a variety of core products and solutions at the Refrigeration Exhibition, focusing on application scenarios such as household refrigeration and heating, commercial refrigeration and heating , and mobile refrigeration . Four of their products won the "Innovative Product" award at this year's China Refrigeration Exhibition.

For example, in the field of commercial air conditioning, the 12-16HP multi-split air conditioner variable frequency rotor compressor of Midea and the newly released ultra-quiet heat pump heating compressor of Midea have won this honor together, and achieve strong output at a speed of up to 140Hz, with the advantages of high energy efficiency and low noise, enabling commercial air conditioners to cool strongly and quickly. In the field of mobile refrigeration, Midea's on-board micro DC variable frequency compressor has the advantages of extreme low noise, miniaturization and high reliability, and can be widely used in mobile vehicle scenes such as car refrigerators, RV refrigerators, medical boxes, and portable boxes. In products such as motors and water pumps, Welling injects strong power into air conditioners and heat pumps with motor and water pump technologies with comprehensive performance upgrades. Welling's green , high-quality, thin permanent magnet motor uses thin and lightweight technology to improve material utilization, while using silent technology to reduce motor operating noise, and uses a number of reliability technologies to optimize and ensure stable and reliable operation of the motor. Its outstanding performance has been recognized by the "Innovative Product" award.

Adhering to the principle of "technology drives everything", GM and Welling have a deep insight into the needs and changes of the HVAC market, and provide end customers with a comfortable and convenient living and working experience with continuous breakthroughs in core technology, innovative products, and lean manufacturing. Looking to the future, GM and Welling will shoulder the responsibility of industry leaders and continue to contribute to the green, efficient, and intelligent development of the global HVAC industry.
