Hitachi compressor, the world's first Understand you better About Hitachi When choosing a home central air conditioner, many attentive consumers will compare the compressor technology of various brands. Because the compressor is the heart of the central air conditioner, the advanced nature of the compressor technology is directly related to the effectiveness and stability of the entire air conditioning system. It’s no surprise that consumers are more concerned about compressor technology. The editor here briefly introduces the advantages of Hitachi compressors. Hitachi patented compressor technology, the world's first! Mainly reflected from the following aspects:
1 Hitachi began research and development in 1970, and manufactured the world's first scroll compressor in 1983 with patents. It has the most experience in scroll compressor manufacturing and application. For more than 30 years, Hitachi has developed to the third generation of compressors. It is the only company in the world that can produce high back pressure combined curve compressors. From the early 1980s to the late 1990s, other brands did not have their own compressor technology, and they did not develop their own compressor technology until Hitachi’s patent protection period expired. In 2003, although the patent protection period expired, but Hitachi invented the high-pressure chamber compressor with internal oil separation, and has a patent. It has become the most advanced compressor in the world. This is why other brands still use the low-pressure chamber compressor technology Hitachi eliminated so far. the reason.
2 Hitachi high-pressure chamber compressor can achieve 12HP, the industry's largest capacity, so the heating speed is strong! Some brands use a single-rotor compressor derived from the technology of the wall-hanging machine (the wall-mounted machine currently uses the rotor compressor), which was later improved to become a double-rotor compressor, and the maximum can only achieve 6HP, so use On the villa machine, the number of compressors is large, and the balance control is difficult, and the result is not particularly ideal. The Hitachi compressor has low wear, low noise, long life, strong stability and good energy saving.
3 Hitachi compressors have an internal oil separation function and have a good running effect. The patented design of the internal oil mist separator and the design of the internal oil return pipe prevent the lubricating oil from being brought to the indoor unit, which effectively solves the capacity reduction caused by the excess lubricating oil in the refrigeration cycle and further improves the system efficiency. Therefore, only Hitachi can achieve rapid heating in 90 seconds.
4 Hitachi scroll compressors have no exhaust parts such as exhaust valves and sliding vanes, and have the lowest failure rate and longest life. Because there is no exhaust valve, there is no pulse noise generated by the operation, so the noise is low.
5 Hitachi uses an asymmetric scroll structure, which can ensure that the refrigerant is fully compressed, reduce the leakage loss inside the compression chamber, and further improve the compressor operation effect and reliability. "Refrigeration is the duty, heating is the ability, Hitachi home central air conditioning, heating effect is good!" In fact, this word of mouth in the industry is not easy to get, mainly due to the credit of Hitachi compressors! If we want to summarize the advantages of Hitachi compressors in one sentence, I think it can be summarized as follows: Hitachi’s large capacity, high pressure chamber, scroll compressor with internal oil separation and asymmetric scroll, the only fourth-generation technology, World number one! Many owners can’t just look at a brand when they choose a central air conditioner for home use. As a result, the price is expensive, and they also buy a product that eliminates technology, which is not cost-effective. For high-end quality, choose Hitachi! Hitachi, a technological enterprise for 100 years!
