'Now China's home central air conditioners only account for a small share. In Japan and the United States, the proportion of home central air conditioners exceeds 70%. As China's consumption upgrade continues to deepen, this must be a huge blue ocean market. 'March 8th , In the 'energy-saving revolution' Gree family central air conditioning inverter variable capacitance technology conference, Jung Dong Group's home appliance division president Liu Jun said.
Liu Jun believes that with the continuous improvement of modern living standards, people's pursuit of quality of life is increasing. Soon, home central air conditioning will become the standard for comfortable homes, which will also be a new growth point for the entire air-conditioning industry. However, domestic central air conditioners still have some inherent disadvantages compared to split-type home air conditioners. The main problem is the large energy consumption.
China Refrigeration Institute's newly released “Investigation Report on the Actual Operation of Refrigeration and Air-Conditioning in China” shows that 60% of home multi-line running time is a single machine, nearly 60% of the time under a 30% load. Under low load The compressor is operating at low frequency and the motor efficiency will also be reduced. At the same time, the low load operation of the compressor will easily reach the critical temperature point of the shutdown. This will cause the compressor to be turned on and off frequently to maintain the control of the temperature.
'Temperature fluctuations and energy consumption will increase with uninterrupted shutdown. For the user, it is neither energy nor comfort.' Cheng Jianhong, researcher at the China Institute of Refrigeration, and a researcher at the China National Institute of Standardization, said that home central air conditioning How to improve operational efficiency through technological innovation is a problem that needs to be solved urgently. It is also an important step for consumers to save money and respond to the national energy saving and environmental protection call.
Cheng Jianhong believes that Gree's innovative frequency-conversion capacity technology in the field of home central air-conditioning has brought the energy saving level of China's home central air-conditioning industry to a new level. Currently, in the field of home central air-conditioning, China’s technology and internationally leading technology phase Although there are still gaps in the ratio, the gap is gradually narrowing.
