Title: Gas turbine plant and thermal storage cooling system
Inventor: NAKAMURA YOSHIHIDE
IPC: F02C7/143
Filed: 1998-11-07
Abstract: PROBLEM TO BE SOLVED: To simplify configuration of a gas-turbine plant that employs an ice accumulator to cool intake air by cooling intake air by means of a heat absorbed when ice or similar substance is dissolved, and by using for intake-air cooling at least part of compressors that compress refrigerant for a refrigerating machine that makes ice. SOLUTION: When accumulating heat through making ice, refrigerant is compressed by compressors 1, 2 and sent to a heat exchanger 3, where it is chilled and liquefied. The resultant liquid refrigerant is expanded as it passes through a throttle valve 11. Ice is made when refrigerant absorbs heat to vaporize at an accumulator tank 4. When intake air is cooled by dissolving ice, on the other hand, refrigerant is compressed by a pump 8 and expanded by a throttle valve 12. Intake air is cooled when the refrigerant is then vaporized at an intake air cooling unit 5. The refrigerant is thereafter cooled and condensed by ice in the accumulator tank 4. When the compressor 2 is used to cool intake air, refrigerant is condensed by the heat exchanger 3 and expanded by the throttle valve 12. Intake air is then cooled as refrigerant vaporizes at the intake air cooling unit 5.

A plate material having the specified thickness is pressed, heat-treated, namely, curburization- hardened and tempered, and an outer race of a double offset-type constant velocity universal joint is manufactured. The surface hardness of the outer race is made in the range of H..58 to 64, and the thickness of a track part and the wall thickness of the inside diameter part are equal to each other. A slide-type constant velocity universal joint is formed by using six balls each of which has the diameter in the range of 13 to 19.5mm. With the lower limit of the wall thickness of the outer race, the (t)/(d) ratio is set to 0.21 or more from the relationship between the failure strength of the outer race of the joint and the failure strength of a shaft. With the upper limit of the wall thickness, the (t)/(d) ratio is set to 0.3 or less since it is necessary for the wall thickness to be set to the mean thickness of the outer race in order to reduce the weight, the (t)/(d) ratio is set to 0.3 or less.
