1. Daikin Air Conditioning: Since the establishment of 1924, Daikin Group has continuously developed and become a multinational enterprise active in the fields of air conditioning, refrigeration, fluorine chemistry, electronics and hydraulic machinery.
2. Hitachi Air Conditioning: Hitachi is one of the top 500 enterprises in the world, ranking 10 in the world. It has strong scientific and technological strength in high-tech industries such as machinery manufacturing, integrated circuits, circuit electronics, nuclear energy and maglev trains.
Second, the characteristics are different.
1, Daikin Air Conditioning: Built-in human body sensor can automatically identify the position and activities of human body. Concentrate the air supply to the area where people live as needed. If there is someone indoors, it will automatically adjust to the low temperature, and when there is no one indoors for a long time, it will automatically close.
2. Hitachi air conditioning: imported Hitachi high back pressure scroll compressor is adopted, and the compressor rotor is made of neodymium magnetic material, which improves the efficiency in an all-round way. Adopting stepless frequency conversion technology, the running frequency of the motor can be adjusted freely to realize stepless frequency conversion.
Third, development is different.
1. Daikin Air Conditioning: With the world-leading technology, we constantly introduce advanced air conditioning products in the China market, aiming at "always meeting customers' needs" and sharing the achievements of scientific and technological progress with the people of China through the unremitting efforts of all staff.
2. Hitachi Air Conditioning: Through the optimized matching design of each link, it can maintain a high COP value regardless of cooling or heating operation, and the highest COP value in the industry can reach 4.53. The whole series of products have passed the national first-class energy-saving certification, and the comprehensive energy efficiency coefficient (IPLV) has reached the top level in the industry.
