On February 10, 2025, the AHR Expo 2025 opened in Orlando, USA. As a system level solution provider for core components of HVAC home appliances, GMCC Meizhi and Welling have unveiled a series of products and solutions developed for the North American market, suitable for household, commercial, and mobile scenarios. The products cover vortex compressors, rotary compressors, reciprocating compressors, motors, etc. applied to all scenarios of North American household air conditioning, commercial air conditioning, heat pump heating, heat pump hot water, refrigerators, window unit air conditioning, automotive air conditioning, and thermal management.
Low temperature heat pump solution helps with comfortable and energy-efficient living
In response to the severe winter weather, frequent blizzards, and freezing rain in North America, Meizhi and Weiling leverage their advantages in rotor and vortex compressors to provide customers with better and higher performance heat pump compressor and motor solutions through the "low-temperature heat pump solution", meeting the needs of consumers in both household and commercial applications.
Thanks to the adoption of variable frequency and EVI (Enhanced Jet Enthalpy) technology, the compressor used in Meizhi heat pumps can significantly improve heating performance in cold climates. Compressors designed with high compression ratio to enhance reliability, low noise, and low vibration are also more reliable and quieter. In addition to high efficiency and energy conservation, the compressor used in Meizhi heat pumps is also compatible with refrigerants such as R454B/R32/R410A, making it more environmentally friendly and providing strong guarantees for consumers' comfort, energy conservation, and green low-carbon life.
In addition to the continuous improvement of product technology, Zhang Qiyun, the market leader of Meizhi and Weiling in the Americas, said, "Meizhi and Weiling attach great importance to the North American market and adhere to localized management, combining local culture and economic characteristics to strengthen technical support and pre-sales and after-sales service capabilities. In 2025, Meizhi and Weiling's research and development center in Dallas will officially start operating in the third quarter, which will provide more support for Meizhi and Weiling to closely meet the needs of the North American market in terms of environmental protection, efficiency, and low noise, and to drive product development and upgrading with consumer feedback
Meizhi rotor and vortex compressor: complete spectrum and higher energy efficiency
In the field of heat pump hot water and heating, Meizhi rotary compressors provide a complete range of compressor products with displacements from 15cc/rev to 58cc/rev, all of which have EVI continuous jet enthalpy increasing function. Thanks to Meizhi's continuous technological breakthroughs and excellent manufacturing capabilities, the product has advantages such as high efficiency, low noise and vibration, and excellent compatibility
In the application of vortex compressors for low-temperature heat pumps, Meizhi variable frequency vortex compressors improve rigidity through enhanced low bearing plate design, effectively reduce noise frequency, and are compatible with environmentally friendly refrigerants such as R32/R454B/R410A, covering commercial and light commercial power sources, making them more widely used.
In the North American market, Meizhi has launched a targeted fixed speed scroll compressor solution for air conditioning and heat pump applications in North America. Through a series of optimizations such as scroll structure optimization, efficient and reliable crankshafts, and high-precision shaft coaxiality, Meizhi has achieved advantages such as high energy efficiency, high reliability, and low noise and vibration.
Weiling Motor: Continuous technological upgrades, full coverage of indoor and outdoor scenes for products
Welling Motor provides a complete product line for the North American HVAC market, including PSC motors, ECM motors, BLDC motors, 3P motors, ER motors, and more. In indoor application scenarios such as air processors, the Weiling PSC motor has an efficiency of up to 74% and stable and reliable performance; ECM motor torque/airflow control accuracy ± 3%, maximum efficiency up to 85%, noise below 45 dB (A), and 6000V surge protection, with high reliability. In products such as gas stoves, the PSC motor used by Weiling for exhaust fans adopts a 4-pole design, as well as explosion-proof capacitor starting, corrosion-resistant, and UV resistant component design, making it more reliable to use. The ECM motor, which is also applied to the heater fan, has a torque/airflow control accuracy of ± 3%, a maximum efficiency of up to 85%, and a noise level of less than 45 dB (A), making it quieter.
In outdoor applications such as air conditioning, heat pumps, and other outdoor units, Weiling offers options including PSC fan motors, constant speed ECM motors, BLDC motors, and more. The market leader of Weiling Motor stated that Weiling Motor will continuously iterate and upgrade its products for ECM motors to meet customers' demands for high efficiency, high reliability, and miniaturization.
Meizhi Ice Pressure: Continuously developing high reliability, high startup capability, and small-sized products
In the fields of household refrigerators, freezers, and commercial refrigerators, Meizhi showcased multiple star products on site, including household ultra efficient variable frequency compressors, household dual suction variable frequency compressors, large displacement compressors for fixed frequency compressors in beverage cabinets, ice cream cabinets, kitchen refrigerators, and ice makers, as well as DC variable frequency compressors for car refrigerators and mobile portable cabinets. With high reliability, high starting ability, and small size, Meizhi has won recognition from customers and consumers. The motor efficiency and electrical control efficiency of the Meizhi household ultra high efficiency variable frequency compressor can reach up to 97%, with a COP of 2.25, meeting the European A-level standard. The low-speed noise is as low as 28dB (A), and the overall noise is as low as 32dB (A), with ultra-low noise characteristics.
With the gradual increase in production capacity of manufacturing bases located in Thailand, India, and China, the number of smart factories globally deployed by Meizhi and Weiling has risen to 14, and the number of research and development centers has also reached 11, further consolidating their technological research and development capabilities and product supply guarantee. In the future, Meizhi and Weiling will uphold the principle of "technology drives everything", rely on the manufacturing layout of "China for global supply+regional supply", adhere to the continuous expansion of technological innovation, product innovation and application, and contribute to the efficient, green and sustainable development of the global home appliance industry.
