本発明は、電源周波数が50Hzの使用域において
冷暖房システムに使用される圧縮機に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a compressor used in a heating and cooling system in a range where the power supply frequency is 50 Hz.

様との２種類を要して部品数が倍増し、部品管理
が複雑になるという問題がある。 Generally, in Japan, the power frequency is
It differs between eastern and western regions, with 50Hz and 60Hz in western Japan, and it is necessary to change the electrical characteristics of the compressor for air conditioning and heating systems to match this power supply frequency. However, in this case, there is a problem that each of the parts used in the compressor requires two types, 50 Hz specification and 60 Hz specification, doubling the number of parts and complicating parts management.

The 60Hz specification is adopted to suit the western Japan region, where there is a high demand for air conditioning equipment due to the climate, and the 60Hz specification is specified for the 50Hz usage range.
A production management system has been adopted that allows the compressor to be used in both power supply frequency regions by using a compressor motor with Hz specifications and correcting the phase using a phase advance capacitor to ensure the power factor. has been done.

欠点がある。 However, such a production control system uses an expensive phase advance capacitor, which tends to increase costs. Furthermore, when a 50Hz dedicated motor with improved power factor is used, the number of types of motors increases, which has the disadvantage that the number of management steps increases.

するものである。 Therefore, in view of these points, the present invention has been developed as described above.
The refrigerating capacity of compressors for air conditioning systems with 60 Hz specifications is made to differ by the air conditioning refrigeration capacity ratio between the power frequency of 50 Hz and 60 Hz, and the compressor has a refrigerating capacity one rank lower than that of the compressor with 60 Hz specifications. By using this electric motor to configure a compressor for a heating and cooling system with a 50Hz specification that has the same refrigerating capacity as a compressor with a 60Hz specification that is one rank lower, the electric motor can be used without using a conventional phase advance capacitor. By increasing the power factor of the product, it is possible to produce at a low cost, and by sharing parts, it is possible to improve parts management efficiency.
The objective is to provide a compressor for heating and cooling systems with a 50Hz specification.
