Advantages and disadvantages of Hitachi central air conditioning

Advantages and disadvantages of Hitachi central air conditioning Hitachi Central Air Conditioning has always been at the forefront of air-conditioning technology, advocating the development and transformation of air-conditioning technology with the height of giants. Advantages: 1. Patented scroll compressor technology, as early as 1983, Hitachi invented the world's first scroll-type air-conditioning compressor and has a patent; and in 2003, Hitachi launched the industry's first internal oil separation function The new high-pressure cavity scroll compressor further improves the efficiency and reliability of the compressor and effectively increases the service life of the air-conditioning host.

Advantages of adding economizer to screw chiller

The temperature control range of the standard screw chiller is 3～35℃, and the efficiency is significantly reduced when operating under lower temperature conditions. In order to meet the temperature requirements of more industries for chillers, make the single-stage screw compressor work according to the two-stage refrigeration cycle and achieve the effect of energy saving, an economizer can be added to the unit.

Application of synthetic compressor oil

At present, synthetic lubricants are widely used in the compressor field. Among them, oil-injected and oil-immersed rotary screw air compressors and large reciprocating compressors are one of the most used markets. For example, the sales volume of synthetic compressor oil in Western Europe was 6000t in the late 1980s, and it rose to 10000 in the early 1990s. The sales volume in the United States has exceeded 15,000 tons, and it is increasing at a rate of more than 10% per year.
