In the context of increasingly tight energy supply, how to produce more energy-saving, environmentally friendly and efficient products is a problem that all manufacturers need to consider. The suspension variable frequency centrifugal compressor launched by Haier has provided us with an answer. Under the fierce competition in the air conditioning industry and the monopoly of foreign technologies, correctly developing our independent innovation technologies is the way for domestic brands to survive. Magnetic levitation centrifuges, with a comprehensive energy efficiency ratio in the industry, are paired with circulating energy air conditioners.
