“…For accurate performance estimation, all the above effects have to be taken into account simultaneously. However, until recently, most published studies [1][2][3][4][5] have analysed them separately. Recently, Chen et al [6] presented the development of a more comprehensive model that combines the compression process with heat transfer between elements of the compressor.…”

The scroll compressor is widely used in air conditioning and heat pump plant because it combines high efficiency and reliability with low noise and vibration. This paper describes a simulation model for estimating the performance of such machines. The model includes consideration of both the compression process and the dynamic behaviour of the moving parts. The compression process is modelled on the assumption of the working chamber as a control volume to which the equations of conservation of mass and energy are applied, allowing for radial and flank leakage and suction refrigerant heating. The derived output from the model includes a pressure-volume diagram of the compression process together with the resultant forces on the components, friction losses within the machine and temperatures of the main components within the compressor. Estimates of the volumetric, adiabatic and mechanical efficiencies of the scroll compressor are then obtained directly from this. Performance estimates thus obtained may be used for the development of the package air conditioning system.

“…For example, Morishita [4] had established the dynamic model of the scroll compressor and studied the characteristics of radial gas force, tangential gas force, and axial gas force. Ishii et al [5,6] further analyzed the dynamic model of the scroll compressor. Kim et al [7] reduced the force of the bearing system by adjusting the phase and weight of the balance weight to generate different inertial forces.…”

With the rapid development of a high-power scroll compressor (HSC), the dynamic performance of a scroll compressor has an important impact on the vibration and noise of the whole compressor. So, the dynamic characteristics and structural acoustic radiation characteristics of HSC under dynamic excitation are studied by simulation and experiment in this paper. Firstly, the dynamic simulation model of HSC is established to analyze the time-domain and frequency-domain characteristics of bearing excitation and upper support excitation. At the same time, the finite element models of housing, upper support, and lower support are constructed to analyze the transient dynamic response of housing under the excitation source. Based on the vibration displacement of the housing surface, the prediction model of the housing radiated noise is also established, and then the radiated noise of the housing surface and the noise spectrum of the standardized test points are analyzed. Finally, the accuracy of the prediction model is verified by acoustic experiments. The experimental results show that the vibration and radiation noise of the housing can be accurately predicted by reasonable modeling to calculate the gas force and approximate the actual gas load. The vibration of the housing coupling system is the main source of the vibration characteristics of the HSC. The conclusions of the study can provide a reference for the low noise design of the HSC.
