Due to the distinct advantages of comfort, drive ability and fuel economy standard, the variable displacement swash plate type compressor which can control the compressor displacement by increasing or reducing the swash plate angle has been developed for automotive air-conditioning system. That can be obtained constant temperature of car room on the variation cooling capacities or engine speeds. This paper was carried out the analysis of swash plate behavior to obtain the forces and moments applied to the swash plate and to get the variable controlability on the variation of compressor speeds and swash plate chamber pressures. The results of simuation agree very well with the experimental data.

That can be obtained constant temperature of car room on the variation cooling capacities of engine speeds. In this paper we investigated the improvement of internally controlled variable displacement swash plate compressor on noise.

A dynamic analysis and friction loss of non-variable swash plate compressor are studied theoretically. Rotating swash plate and reciprocating pistons are modelled kinematically, and forces and torques acting on rotor-bearing system are analyzed. Then, friction losses on 4 roller bearings, 10 sliding parts between swash plate and shoes, and 10 lubricating surfaces between cylinders and pistons are calculated. On each frictional element of sliding surfaces and roller bearings, the same friction loss is obtained, respectively.

In this study, a variable swash plate compressor has been used in a vehicle to improve its fuel efficiency. To manufacture the swash plate, either SCM 435 or UNS C67300 was used. The effects of using different materials for the structural reliability of compressor have been investigated. Static analysis was carried out on swash plate A/C compressor by using commercial software ANSYS 13.0v. The results showed that the Max. stress occurred on the swash plate made of UNS C67300 was lower than that made of SCM435, which indicated that UNS C67300 is more suitable for producing the safe swash plate.

자동차 압축기는 연비 개선효과를 위해 가변 사판형 압축기를 사용한다. 가변 사판의 회전 토크와 피스톤에 작용하는 압력은 사판의 형상과 변형에 중요한 영향을 미친다. 본 논문은 Chebyshev 직교다항식과 최적화 기법을 이용하여 가변 사판의 최적 형상을 결정하였다. 사판의 설계 요구사항은 정상 운전상태에서 최대 응력과 변형을 최소화하면서 체적을 감소시키는 것이다. 직교배열표, 분산분석과 반응표면최적화 방법은 최적 설계변수를 결정하고 주효과를 찾는데 사용하였다. 최적설계 결과로부터, 사판의 유의한 설계변수를 확인하고 이의 최적해와 설계요구조건 만족에 대한 유용성을 설명하였다.

Recently, it is required that the automotive air conditioning system must keep the cabin temperature comfortable in spite of engine speed, and Improve the fuel consumption during all the seasons. To satisfy these requirements, the variable displacement swash plate type compressor with control pressure valve is developed. In this study, the effects of two type valves, suction pressure control valve and differential pressure control valve, on the performance of swash plate type compressor has been investigated experimentally.

최근들어 자동차에어콘 콤프레셔의 전기마그네트식 콘트롤밸브는 내부형 스워시 프레이트형을 사용하고 있다. 이 시스템은 외부로부터 공급되는 전류량(신호)에 의하여 작동되며 동시에 스워시판 작동에 의한 압력은 냉매가 흐르는 비율에 의하여 결정된다. 본 논문에서는 압축기의 크랭크케이스 압력이 전기마그네트 콘트롤 밸브 전기 흐름량에 따른 유량의 값을 측정하여 엔진의 효율을 향상시키고자 한다.
