Earth Hour: Hitachi Central Air Conditioner works with you to speak for the earth The theme of the Earth Hour in 2020 is "Speaking for the Earth". Man and nature are never the relationship between the owner and the subordinates, but interdependence. Nature provides us with all the resources we need for daily life, but now she is indeed facing a huge threat. Born to be human, we should also assume the responsibility of protecting nature. Today is the hour of the earth. Hitachi central air conditioner speaks for the earth. Let us take care of Mother Earth and make friends with nature.
When it comes to protecting Mother Earth, individuals have personal responsibilities, and companies also have corporate responsibilities. Individuals can start with the little things in daily life, such as not throwing garbage, not using chopsticks once, etc. It seems to be an insignificant little thing. In fact, as long as thousands of forces come together, it will be a long-term development for the earth. Say, it is a significant event. For companies, in addition to calling on their employees to protect the environment, producing energy-saving and environmentally friendly products is also one of their responsibilities. For many years, Hitachi Central Air Conditioner has achieved remarkable success in its efforts to improve the energy efficiency of central air conditioners. The IPLV comprehensive energy efficiency ratio is as high as 6.35, far exceeding the industry average, relying on the three core technologies that are leading the long-term. Core energy-saving technology: efficient scroll compressor technology
The compressor is the core of the air-conditioning system. Its continuous evolution represents the continuous improvement of the energy efficiency level of this air-conditioning system. As early as 1983, Hitachi invented the world’s first scroll-type air-conditioning compressor and has a patent. The highly-respected Hitachi Scroll compressors have become the hallmark of revolution in the world's air-conditioning industry. Subsequently, a DC inverter compressor and a new high-efficiency high-pressure cavity scroll compressor with internal oil separation function were successively introduced, which further improved energy saving. After years of development, Hitachi's scroll compressor has possessed more advanced technology, higher quality and stronger reliability. At present, Hitachi is the world's largest scroll compressor manufacturer and the only company in the world that can produce third-generation curved scroll compressors. This is also a key factor for Hitachi Central Air Conditioner to ensure its leading position in the industry. More efficient stepless frequency conversion technology: DIP-IPM frequency converter
Another core technology of Hitachi central air-conditioning with high efficiency and energy-saving is DIP-IPM frequency converter. In addition to the frequency conversion function of ordinary frequency converters, it also integrates PFC (power factor correction), noise reduction, rectification, filtering, driving, and overcurrent protection. And anti-thermal drift and other functions, not only has excellent control accuracy, but also has strong stability. With the help of DIP-IPM frequency converter, the operating speed of the DC inverter compressor of Hitachi Central Air Conditioner can be continuously adjusted freely. The control accuracy of 0.01Hz can truly achieve stepless frequency conversion, which is more comfortable and energy-saving. Comfortable and energy-saving, warm with your heart: intelligent control system
Hitachi is one of the world's best industrial chip manufacturers, a leading automatic sensing and intelligent control system. Not only can it be more user-friendly in the diversification of remote controllers, remote control, and equipment control such as building automatic control and household metering systems, it can also achieve five-level energy-saving operation, without the need for additional signal lines, and automatically perform current self-detection and automatic control limits Electricity. At the same time, according to the different needs of users, you can choose a variety of control modes to achieve a balance between energy saving and comfort, and gradually guide consumers' energy saving awareness and environmental protection awareness in behavior, highlighting the significance of energy saving in management.
In modern society, central air conditioning is undoubtedly one of the most important inventions for a comfortable living environment. How to make everyone enjoy the comfortable life brought by modern technology, reduce carbon emissions with less energy consumption, and create more The bright future is the beginning of every enterprise that Hitachi Central Air Conditioning has been practicing. The continuous breakthroughs and development of its own technology are the best proof of Hitachi Central Air Conditioning's unremitting efforts to improve product energy efficiency. For an hour of the earth, Hitachi central air-conditioning will work with you to save energy, reduce emissions, protect nature, and speak for a more sustainable planet.
