Own development and internal production of "2-cylinder rotary compressor"
|
|
 |
|

Our company developed a high efficiency DC inverter type "2-cylinder rotary compressor" (N-TF30ND) for middle and large size air conditioners (cooling capacity 8kW – 15kW) by own technology aiming to start internal production from October, 2009.
For the internal production, the current factory of FGA (THAILAND) CO., LTD., motor manufacturing company for air conditioners in Chonburi, Thailand of our 100% investment, will be expanded and production lines for compressors will be set up there. The construction of the new factory will start from August this year and operation is scheduled to start from October, 2009. The production capacity of compressors is 400,000 units for the first year. The aggregate investment amount is approximately 3.5 billion yen.
Recently, as global approach is required to environmental problems, the energy-saving regulations for air conditioners in various countries of the world are becoming increasingly strict as seen in the level-up of standard value to achieve and enforcement of Energy-saving Labeling System. Under such circumstances, our company has been tackling positively the enhancement of energy-saving performance.
In order to pursue higher level of improvement in the future, the efficiency improvement of compressor which is a key component of air conditioner is one of the most important themes.
We have been procuring all compressors from external source so far, but for strengthening the middle and large size air conditioner field, we have been continuously making the research and test production of our own compressors for the past several years considering that one of the most important themes is to develop the most suitable compressors for our air conditioners, and then, the development of our own compressors for middle and large size air conditioners has been completed with internal production to follow.
The high efficiency DC inverter type "2-cylinder rotary compressor" (N-TF30ND) with high energy-efficiency even for wide load fluctuations was developed taking the future energy-saving regulations into consideration. Furthermore, by optimizing the structure within the compressor, it was made possible to cut the volume of discharge oil by half and reduce the loss of heat transmission of heat exchanger and also the installation of long piping required for building and large-scale facility was made available.
We will positively tackle the global environmental problems and make efforts for further expansion of air conditioner business.

Main features of DC inverter type "2-cylinder rotary compressor"
1. High efficiency designing taking future energy-saving regulations into consideration
Under the circumstances where the energy-saving regulations for air conditioners in various countries of the world are becoming increasingly strict as seen in the level-up of standard value to achieve and enforcement of Every-saving Labeling System, the compressor developed by our company this time is designed to optimize cylinder volume and cylinder diameter to maintain the high efficiency in the wide operating range from low speed to high speed taking future energy-saving regulations into consideration. Also, in order to make use of operating characteristics of DC motor to deal with load fluctuation, magnetic circuit is designed by utilizing magnetic field analysis technology for optimization.
Thus, we have achieved energy efficiency improvement by 5% compared with equal class of compressors of competitors.
2. Reduction of discharge oil by half
A part of lubrication oil inside the compressor is discharged outside, but in case of excessive discharge oil, cooling performance of air conditioner is declined or burning of bearing can be caused by lowering of the oil level inside the compressor.
In the compressor we developed this time, the ratio of lubrication oil contained in the circulating refrigerant is cut by about 50% compared with equal class of competitors' products and the loss of heat transmission is reduced and, at the same time, the long piping required for building and large-scale facility is designed to keep sufficient lubricating performance.
