Hydrogen Compression Challenges for Net Zero Targets Engineered Solutions, United Kingdom Everyone is now familiar with Governments’ ambitions for ‘net zero’ greenhouse gas emissions by 2050 and many believe that Hydrogen will be a major building block to achieve this target. Whether or not this will be the outcome, the compressor industry needs to be prepared for major challenges in meeting the huge, anticipated demand in what has hitherto been a fairly niche market. This paper will examine the present levels of experience with hydrogen compression in six specific identified applications within the Hydrogen Value Chain (H2VC) and examine the main challenges facing further development of hydrogen compression to meet the Net Zero Targets in these areas. The hydrogen compression market is currently dominated by low-speed process industry (API618) reciprocating compressors; these are very well proven on hydrogen but have relatively low volumetric flowrates and high capital cost. At smaller volumetric flowrates, new types of compressor are becoming available or are under development but the only alternatives for larger flowrates are centrifugal and rotary screw types, which have much greater swallowing capacity but have been little used in the past for pure hydrogen. Ian Arbon draws from his decades of experience in sustainable development, hydrogen compression and climate change mitigation/adaptation to examine the current state of play in the industry. |

Comparison of PV-diagrams between CFD and experimental results for twin-screw compressors Carrier Corp, United States of America As technological advances emerge at breakneck speed, efficiency, and robustness of design drives innovation in the field of compressors, expanders, and pumps. At the core of such exploration rests the notion that experimental validation is needed to prove the concept and efficacy of novel designs. Unfortunately, due to limits in instrumentation and experimental setup, it is sometimes infeasible to grasp the physics behind complicated phenomenon solely through experimentation. Experimentation results can provide an incomplete picture which may in turn force an incomplete solution to be incorporated into the product design. Using an experimentally validated CFD model in conjunction with existing experimental results allows for an unexpurgated view of the broader system. One such instance of this problem is experimentally producing the pressure – volume (PV) diagram of a twin – screw compressor with an attached economizer. Due to instrumentation limitations caused by the geometry, the PV diagram is created by adjoining several pressure transducers placed along the female rotor. However, drawing a conclusion from this PV diagram is incomplete because comparing the result against the validated CFD model show that the pressure behavior exhibited in the experimentally created PV diagram is only local to the neighborhood of the pressure transducers, whereas the CFD model show that a continuous view of the compression process exhibits a smoother average pressure transition within the entire volumetric pocket. By combining experimental results along with the appropriate CFD model allows for a broadened understanding of the underlying physics that cannot be achieved solely through experimentation. Influence of bearing and seal design on performance of an oil-injected screw compressor for refrigeration applications 1City, University of London, United Kingdom; 2Mayekawa UK Ltd, Glasgow Screw compressors are key components in a range of refrigeration and air conditioning applications. It is essential that the design and operation of these systems is optimised to ensure energy efficiency and reliability. An important aspect of the compressor design is the choice of bearings used to support the twin helical rotors. These bearings must be capable of providing the reaction forces required to accurately locate the rotors across a defined range of inlet and discharge pressures for machines with a range of volume ratios and operating speeds. This paper explores the selection process for both rolling element and hydrodynamic bearings. The influence on compressor performance of these bearings can be defined in terms of the frictional power losses and required oil supply flow rates. Bearings can also have indirect influence on overall compressor efficiency, due to the potential introduction of leakage paths of process gas through low-pressure bearing oil drains. Therefore, additional sealing requirements for each bearing type are investigated, allowing an assessment of leakage flow and frictional power loss of bearing/seal systems and their influence on the overall performance of different compressor configurations in terms of energy efficiency, lifespan and maintenance requirements. Simplified engineering calculation methods of the temperature distribution along the screw compressor rotors 1Kazan National Research Tehnological University, Russian Federation; 2Chelyabinsk Compressor Plant, Russian Federation A purpose of a screw compressor experimental prototype development, rotor profiles design of optimization has many engineering problems. One of the main of them is trying to predict on this stage the compressor construction parameters, which are as close to the optimal as possible. Using of the compressor mathematical model for this aim sometimes is impossible, because of hardness of new mathematical model design and necessary of their accuracy checking. Therefor there is a necessary to have not only high-accuracy calculation tools, such as mathematical model, but also have some simplified engineering methods for the fast calculation of compressor parts’ conditions, which have enough accuracy for the first stage of the development at same time. These conditions also include the temperature field of the compressor rotors. The presented paper dedicated to the analyses of possibility to obtain approximation equations, which can be used for the calculation of the preliminary value of the screw compressor rotors’ temperature fields depending on the operation mode and construction parameters of the screw compressors |

Preliminary design and performance evaluation of micro scroll compressor used in refrigeration systems Qingdao University of Science and Technology, China Micro refrigeration systems can be used in many applications. Micro scroll compressors have the potential for application in these refrigeration systems. With its miniaturization, the clearance and geometry parameters have become more influential in the performance of scroll compressors. In this paper, several three-dimensional flow models with different pitches, thicknesses, and leakage clearances are established. These models are designed by the control volume method with R134a as the working fluid. By using the CFD method, the temperature distribution, pressure distribution, and flow characteristics in the working chamber are analyzed. By comparing compressors with different pitches and thicknesses, the effect of pitch and thickness on the volumetric efficiency and isentropic efficiency is obtained. By changing the radial and axial clearances, the change trends of the efficiency are obtained. The results provide a reference for the design of micro scroll compressors. A Study to Improve Efficiency of a Variable Speed Scroll Compressor Trane Technologies A study using a 1D chamber model was done to improve isentropic efficiency of a variable speed scroll compressor and then testing was conducted to validate. It was noticed in the initial analysis that the economizer location, sizing, and timing optimization gave an efficiency improvement of 0.5% to 2.5% depending on the operating point. Since the economizer was optimized for location, area and timing or activeness, the back flow was reduced, hence the mass flow through the port and efficiency improved. A study with focus on speed resulted in an improvement in weighted efficiency to the tune of 4-6% . Investigating the effect on port delay showed, improvement was on a rising trend as the discharge port delay was increased until around 110 degrees and then efficiency started to decline. The improvements for different operating conditions were in the range of 2%-4%. An improvement in involute start angle also resulted in improvement in efficiency to the tune of 0.7% to 1.3% depending on the operating condition. Changing this parameter affected the structural integrity, hence not adapted.A new compressor was built with new economizer port geometry to understand the effect. The results were promising with variation in efficiency from -0.6% to 5.1% for different operating conditions investigated. Speed sweeps showed there are peak efficiency points, which can be used to decide the speed for operating condition. |

Feasibility Study on Two Novel Lubricants for Carbon Dioxide Reciprocating Compressor 1Herrick Laboratories, School of Mechanical Engineering, Purdue University, West Lafayette, IN, USA; 2Evonik Oil Additives Inc., Darmstadt, Germany In recent years, increasing research efforts have been made on modeling and testing positive displacement compressors with low global warming potential (GWP) working fluids and their systems. The ongoing HFC phase-down is forcing the HVAC&R industry to investigate low-GWP refrigerant alternatives as well as natural refrigerants (e.g., water, hydrocarbons, CO2). The transition to low-GWP and natural refrigerants requires research efforts on cycle configurations and components including compressors. More specifically, most of the existing positive displacement compressors employed in HVAC&R systems rely on lubricant oils to ensure correct operation and performance. To better understand the potential research directions in lubricant oils, a reciprocating compressor with CO2 as refrigerant was selected as the case study to investigate alternative lubricant oil formulations. In this study, a baseline POE-68 and two alternative lubricant oils were evaluated on a transcritical CO2 reciprocating compressor with respect to performance enhancement and potential issues and challenges. A hot gas bypass test stand was used to carry out the experimental studies. A total of 66 steady-state data points were collected, and control tests were performed after each alternative oil formulation to ensure correct operation of the compressor. The alternative lubricant oils showcased comparable performance data to the baseline lubricant oil under a wide range of operating conditions without sign of decomposition. Numerical analysis of the dynamic two-phase flow behavior in the ionic compressor with a novel H-shaped piston Xi’an Jiaotong University, People's Republic of China With the development of the hydrogen energy industry, it is crucial for hydrogen refueling stations that compressors can work efficiently and flexibly with a longer life span. Adopting ionic liquid as a liquid piston to compress hydrogen is a feasible method. The high stroke frequency of ionic compressor prevents the liquid piston from maintaining a stable shape, leading to the generation of the additional clearance volume and hydrogen sealing failure. In this article, a novel H-shaped piston was proposed and a 3d numerical model of an ionic compressor cylinder with it was established. The dynamic simulation of the two-phase fluid behavior in the cylinder during three cycles was performed using the volume of fluid method and the dynamic mesh technique. The effect of this piston on the variation of the two-phase interface and the clearance volume of the compressor has been discussed for optimizing the design of the ionic compressor. Results show that: the clearance volume of the cylinder with a H-shaped piston was smaller than that of the cylinder with a normal piston in all three compression cycles, which indicated that the higher volumetric efficiency could be obtained with the H-shaped piston. In addition, the application of the H-shaped piston allowed sufficient ionic fluid to be retained in critical sealing locations of the cylinder to keep hydrogen sealing and piston lubrication well. Parametric analysis and investigations in crankshaft design for the reciprocating compressors 1Arcelik Central R&D, Turkey; 2Arcelik Compressor Plant, Turkey; 3Koc University One of the most crucial parts of a reciprocating compressor is the crankshaft, which conveys the motion of the rotor to the piston via the connecting rod. The effect of the gas, friction and inertial forces on the journal bearings not only creates the vibration but also initiates the mechanical losses. Since the design parameters of the crankshaft play a vital role in the losses, in this study, the bearing and lubrication model of a reciprocating compressor was developed in an analysis software to investigate the effect of design parameters. The forces and the torques emerging on the compressor were calculated and in-directly validated with mechanical loss experimental studies. Afterward, a sensitivity analysis is made by sweeping varying design parameters, and vital parameters are identified for the crankshaft to reduce the bearing loads and mechanical losses. Finally, a crankshaft design that demonstrates lower bearing forces than the investigated geometry is proposed with the genetic algorithm.

3D printing for compressor Design: Limitations and advantages Nanyang Technological University, Singapore The advancement of 3D printing technology has revolutionized many manufacturing processes. When utilizing this technique for compressor design, conventional approaches and thinking processes must be changed. In this talk, we will examine the limitations and advantages of using 3D printing techniques for compressor design. Compressors are intricate mechanical systems, and the design process is complex, requiring precise dimensional accuracy. However, 3D printing provides several benefits that make the design and manufacturing process more efficient, cost-effective, and customizable. One of the primary advantages of 3D printing is the capability to produce highly detailed and intricate designs that are difficult to achieve with traditional manufacturing techniques. This enables designers to create compressors that are potentially more efficient, with improved performance. Additionally, it allows for the rapid creation of custom parts, reducing lead time and cost in the design and fabrication process. It also enables rapid prototyping and fabrication, leading to decreased lead times. Traditional manufacturing techniques necessitate expensive jigs, fixtures, and molds, whereas 3D printing may not necessarily require all these intermediate stages of processes. During this talk, we will provide brief details on each of the available 3D printing techniques, their respective advantages, and disadvantages. In conclusion, 3D printing has the potential to transform the design and manufacturing process of compressors. With the ability to create intricate designs, custom parts, and reduce lead times, along with cost savings and the use of various 3D printing technologies, the opportunities for utilizing this technology in improving compressor design and performance are highly promising. |
