Chris Seeton is widely considered to be an expert in the compressor/refrigerant industry. He has the notable distinction of being the person who won the first battle that allows new low global warming refrigerant regulations to come into effect by serving as the Global Technology Leader at Honeywell and leading the industry’s effort to replace R134a with R1234yf which came to fruition in 2015 (an EPA CAFÉ credit of 13.8 gCO2/mile or ~3 mpg per vehicle by just changing the refrigerant). Even today, he continues to drive change in the industry by leading two cooperative research project groups through SAE on developing new heat pump systems for electric vehicles.

Regulatory Uncertainty Drives Demand for Explosion-Proof Technologies to Support the Development of New Refrigerants

Air conditioning systems use refrigerants to do the job of cooling an indoor space. These refrigerants, in the form of hydrochlorofluorocarbons (HCFCs), potentially contribute to climate change, and are currently being phased out of use in the United States. The phaseout approach, which was initially started in 2010, gives manufacturers time to develop ozone-friendly refrigerants as an alternative.

Finding the right balance of lubricants and refrigerants in compressor design

May 11, 2021 8:08:00 AM / by Patrick Riley posted in 571 sensor, viscosity management, compressor viscosity, process viscometer

0 Comments

When it comes to air conditioning and compressor systems, achieving ideal operating efficiency is about balance. Too much lubricant means the compressor or cooling system won’t cool properly, and too much refrigerant increases bearing wear and reduces the system life. Thicker oil lubricates better, but it also means there is an increase in drag, and more power is needed to rotate the compressor. Manufacturers must consider all these variables when manufacturers designing their equipment. Each new design requires significant testing to ensure performance and energy efficiency.

VISCOpro Used in Research to Analyze Viscosity in a Rotary Compressor

Apr 29, 2021 8:31:44 AM / by Patrick Riley posted in 501 sensor, viscosity measuring solution, viscosity control, research, compressor viscosity

When compressor manufacturers design a new compressor model, part of the process includes determining the type of refrigerant and the accompanying lubricating oil, which is necessary to reduce friction on metal parts, reduce wear on the compressor, and extend the life of the system. The company must conduct extensive testing to ensure proper energy efficiency and functionality. The lubricant has a significant impact on the performance of the compressor. Over-lubrication can impact the compressor’s ability to cool properly, but too much refrigerant will lead to more wear and a shorter compressor lifecycle.

Oil condition monitoring for online lubrication oil monitoring on gas screw compressors

Managing lubricant viscosity is essential to maintaining the health of a compressor in a process plant, because a single compressor failure can cost $10,000 a day or more in lost revenue. Considering it’s another $10,000 to rebuild a compressor, or more than $100,000 to replace a compressor, maintaining the health and performance of compressors is important.

Boston—Machinery failures, downtime and maintenance labor costs can kill a refiner’s bottom line profits.  A major US oil company with refinery installations in North and South America has installed several Cambridge Viscosity VISCOpro viscometers to monitor oil viscosity, providing engineers with real-time information on oil quality. The viscometers utilize Cambridge’s 392 process sensors and are Class 1 Div 1 Group B, C, and D certified.

Lube Oil Viscosity Testing For Optimal Compressor Performance

Jul 18, 2018 12:00:00 AM / by Admin posted in VISCOpro2000, process viscometers, lube oil, lube oil viscosity, 571 sensor, compressor viscosity

Boston—Danfoss Compressors is using a Cambridge Viscosity small sample viscometer to test refrigerant and oil mixtures at their Tianjin, China factory.

The viscometer includes the Cambridge VISCOpro2000 electronics and SPL 571 lube oil viscometer sensor with multiple piston ranges to test compressor performance using new combinations of lube oils and refrigerants. The lower the viscosity of this mixture, the more efficient the compressor is. However, if viscosity is too low, the compressor can wear out prematurely. By achieving the optimal balance of efficiency and lubricity, the company can improve compressor performance while using more environmentally friendly refrigerants.

Danfoss engineers cite the viscometers’ ease-of-use, robust functionality and high degree of accuracy among the chief reasons for their use. The VISCOpro2000 enables users to monitor critical fluid processes and capture real-time data. The addition of the 571 sensor—used extensively for compressor, used oil analysis, on-engine and hydraulic fluid applications—provides for installations where form factor and small sample volume are important. “Danfoss was restricted in the amount of area they had, and Cambridge’s miniature lube oil viscometer is the perfect choice when limited to tight spaces,” explains Cambridge Viscosity China Agent Miker Wang of Suzhou TAIEN.
Cambridge’s viscosity management technology is based upon a simple and reliable electromagnetic concept. Two coils move the piston back and forth magnetically at a constant force. Proprietary circuitry analyzes the piston’s two-way travel time to measure absolute viscosity. A built-in temperature detector (RTD) senses the actual temperature in the sampling chamber. Constant in and out motion keeps samples fresh, mechanically scrubs the sampling area and provides excellent viscosity tracking.
