Under the influence of the European energy crisis and related policies, the number of heat pump sales in Europe in 2022 reached 3 million units, a record high. Heat pump has become a key buzzword in the entire HVAC field. However, while heat pump products are selling well, the noise problem has always plagued the development of the industry and affected the user experience. Therefore, with the precision frequency control and silence technology of Meizhi heat pump compressor, especially the improvement of low frequency noise reduction capability, it will bring a breakthrough for the silence and noise reduction of heat pump machine products:

Using the global arc magnetic adjustment technology, the stepped rotor is round, the tooth groove torque is reduced by 80%, and the electromagnetic excitation force is reduced by 31%.
The pump body of the compressor adopts double M support fixed liquid reservoir design, and the fixed frequency is increased by more than 300%.
The optimal balance coefficient of the balance block and low rotor installation design achieve low deflection and high swing frequency, swing frequency increased by 60% and vibration decreased by 80%;
The silencer adopts the lower cavity straight row holes, the pulsation amplitude decreases by 90%;
Finally, through the precise structure control technology, GMCC precision frequency control silent R290 heat pump compressor to achieve noise reduction in the sensitive frequency segment, low frequency noise reduction of up to 6 dB. As one of the promoters of the global environmental refrigerant replacement process, GMCC has a comprehensive R290 refrigerant product line and product matrix, covering air conditioning, mobile air conditioning, refrigerator, refrigeration, light business, as well as heat pump heating, heat pump dryer, heat pump hot water, etc., and with miniaturization, low oil content and other research and development technology and application. The R290 efficient and environmentally friendly compressor combines safety, reliability and energy efficiency to win market and customer recognition.

In the future, GMCC will rely on the continuous innovation of the Group’s three-level research and development system in cutting-edge technology layout, basic technology breakthroughs and new technology applications, and contribute more to the continuous expansion of heat pump application scenarios and the comfortable experience of consumers.
