摘要： PROBLEM TO BE SOLVED: To obtain a stator core device for dynamo-electric machine where vibration and noise are reduced by eliminating the gaps between core bolts and a stator core or bringing the core bolts and the stator core into tight contact with each other.
SOLUTION: Core bolts 2a, having circular cross sections, are fit into a plurality of grooves having arc-shaped cross sections, formed on the circumference of the cylindrical stator core 1, which is formed by laminating steel plates, which grooves are positioned at equal intervals and in parallel with one another in the axial direction. Then, support rings 3 are placed on the circumference of the core 1, to reduce the spacing between tightening seats 31, and the core 1 is thereby tightened via the core bolts 2a from the circumferential side. The core bolts 2a and support rings 3 in tight contact with each other are welded together at the inner circumferential portions of through-holes 33 formed in the support rings 3. Further, auxiliary rings 10 are placed between the support rings 3, and the stator core 1 is tightened via the core bolts 2a to constitute a stator core device for dynamo-electric machine.

摘要： PROBLEM TO BE SOLVED: To simply maintain a stably cooling operation by lowering an operating frequency of a compressor to a predetermined frequency at the time of sensing a characteristic value corresponding to a discharge refrigerant pressure preset by a sensor, and raising the frequency of the compressor to a predetermined frequency at the time of sensing no value. SOLUTION: At the time of operating air conditioning, a control means judges whether an indoor temperature is a set indoor temperature or higher or not. In the case of YES, it judges whether an outdoor temperature is a set outdoor temperature or higher or not. In the case of YES, it judges a sequence flag code of the compressor 2. When the code is '0', the operating frequency of a compressor 2 is set, for example, to 45 Hz, and then whether a discharge gas pressure switch 5 is operated or not is judged. In the case of YES, the operation of the compressor 2 is stopped. Meanwhile, in the case of NO, whether 45 Hz operation is conducted for a set time of predetermined minutes or more or not is judged. In the case of YES, the code is set to '2', and the frequency of the compressor 2 is set, for example, to 60 Hz.
