This paper describes a simulation model for estimation the performance of the swash plate type compressor for automotive air conditioning system. The model includes consideration of both the compression process and the dynamic behavior. Also, this study compares the results obtained from the performance simulation with experimental results. Further, the effects of the inclined angle of swash plate on the performance of swash plate type compressor are discussed.

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.

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.

The automobile air conditioning system generally consists of laminated type evaporator, swash plate type compressor, condenser, expansion valve and receiver drier. A swash plate type compressor has been used widely in automobile air conditioning system since 1955, because of wider operation range and better durability than other type compressors. In this study, the performance of an swash plate type compressor with variations of oil charging conditions has been investigated experimentally using the hot gas system. Further, the effects of varying compressor speed on the performance of the compressor has been discussed.

Recently, from the viewpoint of global wanning, natural gas CO2 is considered as a main refrigerant for hot water system. The characteristics of CO2 is not toxic, not flammable, high pressure, and high refrigerating capacity. Also it is widely available as a byproduct of industrial processes. This paper describes the performance analysis program of the swash plate type compressor using CO2 refrigerant. Estimates of the refrigerant flow rate, compression work, discharge temperature and volumetric, compressor efficiencies of the CO2 swash plate type compressor are obtained from the various design parameter such as the inclination angle of the swash plate, discharge hole area and suction hole area.

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.

The dynamic behavior of rotor-bearing system used in swash plate compressor has been investigated using the combined methodologies of finite elements and transfer matrices. The finite element is formulated including the field element for a shaft section and the point element for swash plate, disk pulley and bearings. The Houbolt method is used to consider the time march for the integration of the system equations. The transient whirl response of rotating shaft supported on roller bearings is obtained, considering compression forces and unbalance forces at swash plate and driving pulley. And, the steady state displacements of the rotor are compared with a variation in unbalance mass. Results show that the loci of rotating shaft considering unbalance forces and external compression forces are more severe in flutter motion than with only unbalance forces.
