The joint bearing on a wobble plate is a critical component of the drive system, but its motion characteristics are complex, and currently lacking a motion model. This study develops a composite motion model for the wobble plate in airborne wobble plate compressors with both bevel gear and roller-straight groove anti-rotation designs, using a microelement method. The result shows that the wobble plate simultaneously rotates around an instantaneous axis within its plane and its normal axis, exhibiting similar behavior in both anti-rotation types with minor deviations below 5 % in angular velocity and 20 % in axis when the inclination angle is less than 25°. The motion characteristics of the joint bearing's ball socket relative to the ball head mirror the wobble plate, with equal rotational velocities and parallel axes. This theoretical model is validated through ADAMS simulations, achieving a high level of accuracy with less than 1.5 % deviation in maximum relative sliding velocity at the selected point in both anti-rotation structures. The research further investigates the influence of compressor rotation speed, wobble plate inclination angle, and joint bearing radius on the maximum relative sliding velocity, revealing an approximately proportional relationship. The area with the maximum time-averaged relative sliding velocity is located near the bottom of the ball socket, suggesting a potential wear hotspot. The experimental observation of morphology confirms this.

To address this critical gap, this study delves into the influence of spraying condensate water and introduces the critical flowrate - the maximum flowrate at which all condensate water is entirely evaporated. The impact of some key factors, such as the flowrate of condensate water, the nozzle number, the spraying distance, and the ambient temperature and humidity, are experimentally discussed.

The critical flowrate is inherently lower than the optimal flowrate. Increasing the nozzle number, spraying distance, and decreasing ambient temperature and humidity, could improve the ORDC performance, and the corresponding critical flowrate could be also increased. The critical flowrate is almost the same for different conditions.

In deep space applications, the JT orifice load is fixed, and takes time to achieve in low temperature. This paper presents a closed platform with a regulating valve to simulate JT loads in room temperature. Experiments are carried out to study the effects of stroke and frequency on the output characteristics of a single-stage VLC with different valve openings. The results show that increasing the valve opening reduces the load, increases mass flow rate and exergy efficiency, slightly decreases pressure ratio, and alters motor efficiency. Either increasing frequency or stroke enhances both the mass flow rate and pressure ratio. Under a load of 2-turn opening(Φ=1E-4 m), the stroke length increases from 0.002 m to 0.008 m, thereby causing the pressure ratio to exceed the reciprocal of the critical pressure ratio (1/λ*=2.04), suppressing growth rate of the mass flow rate from 44.7 % to 2.2 %. This suppression means the rest of the stroke can't play more functions, and it is attributed to choked state of the working medium, which can be identified by comparing experimental and theoretical mass flux values of the VLC. It also suggests that there exists a matching relationship between the compressor and the JT load, offering a basis for the compressor design and the match with JT orifice.</div></div>","PeriodicalId":14274,"journal":{"name":"International Journal of Refrigeration-revue Internationale Du Froid","volume":"174 ","pages":"Pages 176-184"},"PeriodicalIF":3.5,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143681027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these issues, this study focuses on identifying anomalous data by analyzing the normal operations of chilled water systems and examining their characteristics in the frequency domain over both short- and long-term periods. Based on this analysis, two distinct anomaly detection schemes are proposed: a low-frequency detection (LFD) method, which focuses on low-frequency data, and a frequency-domain segmentation detection (FDSD) method, which separately considers high- and low-frequency components. Unlike previous approaches, the proposed LFD and FDSD comprehensively integrate both time-domain and frequency-domain characteristics while determining anomaly detection thresholds without requiring anomalous data. Experimental evaluations on the ASHRAE RP-1043 dataset demonstrate that FDSD achieves a detection rate of over 90 % under varying background conditions for subtle anomalies that are typically difficult to detect.
