本発明は、冷凍能力が複数ランクに異なる複数

縮機シリーズに関し、特にその電気的特性を電源
周波数の60Hz仕様としたものに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a compressor series used in air-conditioning systems that includes a plurality of compressors with different refrigeration capacities in a plurality of ranks, and particularly relates to a compressor series whose electrical characteristics are specified as a power supply frequency of 60 Hz. .

リーズに生産されている。 Conventionally, this type of compressor series for heating and cooling systems has typically been, for example, 2.5 horsepower, 3 horsepower, 4 horsepower,
5 horsepower, etc., etc., are produced in compressor series with different refrigeration capacities, even with air conditioning refrigeration capacity ratios of approximately 1.25 (125%).

いう問題があつた。また、それ故、市場ニーズの
多様化に対応することができない嫌いがあつた。 However, in the compressor series produced in this way, the air conditioning refrigeration capacity ratio between ranks is relatively large, approximately 1.25, so the required air conditioning refrigeration capacity of the air conditioning equipment is not matched to the air conditioning refrigeration capacity of the compressor of each rank. If not, a compressor of a higher rank must be used, resulting in a problem of wasted energy. Also, because of this, there was a dislike of not being able to respond to diversifying market needs.

工数が増大するという欠点がある。 On the other hand, in Japan, the power frequency is 50% in eastern Japan.
Hz differs between the eastern and western regions, with 60Hz in the western Japan region, and it is necessary to change the electrical characteristics of the compressor series to match this power frequency. The 60Hz specification was adopted to suit the western Japan region, where there is a high demand for air conditioning equipment.
For the 50Hz usage range, the 60Hz specification compressor mentioned above can be used as is, and the motor can be used with the phase corrected using a phase advance capacitor to ensure the power factor, making it possible to share the compressor series. There are many things being done. However, in this case, there was a problem in that the cost increased due to the provision of the phase advance capacitor. Furthermore, when a 50Hz dedicated motor with improved power factor is used, there is a drawback that the number of types of motors increases and the number of management steps increases.

んとするものである。 Therefore, in view of these points, the present invention sets the electrical characteristics of each compressor in the compressor series to 60Hz specifications, and the refrigeration capacity of each compressor is determined by the ratio of the air conditioning refrigeration capacity when the power frequency is 50Hz and 60Hz. However, by making them different, in the 50Hz usage range, it is possible to create a series equivalent to the 60Hz specification, corresponding to the refrigerating capacity of the compressor one rank lower than the 60Hz specification, and thus the number of compressor series. 60Hz, which can respond to the diversification of market needs by increasing the
We aim to provide a compressor series for heating and cooling systems with specifications.

果を有するものである。 As described above, according to the present invention, the refrigerating capacity of each compressor in the compressor series for air conditioning systems with 60Hz specification is made to be different even in the air conditioning refrigerating capacity ratio of approximately 50Hz and 60Hz. In contrast, it is possible to configure a compressor series with a 50Hz specification in response to the refrigerating capacity of a compressor one rank below the 60Hz specification, thereby increasing the number of compressor series and meeting market needs. In addition to being able to provide good support and optimize the compressor characteristics, it also has practical advantages in that it reduces costs by eliminating the need for conventional phase advance capacitors, and improves the efficiency of parts management by reusing the compressor. It is effective.
