Europe’s F-Gas Phase-Out, Price Increases, Leave the Industry Looking for Solutions

In Europe, the phase out of fluorinated gases with high global warming potential, known as F-gases in Europe and HFCs in the U.S., is resulting in severe shortages, causing prices to skyrocket and creating challenges for those that operate and maintain the systems.

From Threat Assessment to Employee Engagement: IIAR Tech Papers Unveil Research, Analyze Data

Utilizing bow-tie graphics to assess and prevent potential threats to an industrial ammonia refrigeration system, the importance of employee engagement and building relationships with first responders, and the benefits of ammonia scrubbing with C02 are among the technical papers and workshops that will be presented at this year’s annual IIAR Natural Refrigeration Conference and Expo.

Efficiency Can be Just Another Controllable Cost

Energy efficiency can be achieved in ways other than with new technology. It can also prove to be a controllable cost, just as with labor and equipment. By developing an energy management system that establishes clear, measurable goals for energy performance, end users of industrial refrigeration facilities can realize a significant reduction in energy consumption, delivering cost savings that fall straight to the bottom line.

Little Details Add Up

When big things happe they really draw our attention, but in most cases it’s the little things we miss that can result in unexpected and sometimes undesirable results. We might breeze along taking account of larger items, not realizing or taking time to think that little details can make a big difference.

Social Security: Claim Early and Invest Versus Delaying Receipt for Increased Benefits

Financial Advisors are occasionally asked to provide an analysis of the potential results of claiming Social Security early and investing the proceeds versus delaying receipt for increased benefits, which can be claimed as late as age 70. The following are the reasons that delaying social security income can be a prudent strategy.

Using the Right Type of Monitor for CO2

The use of CO2 is becoming common in the industrial refrigeration industry, especially with cascade refrigeration systems. But many people are not as familiar with CO2 as they are with ammonia, some believing that the only respiratory issue with CO2 is that it is an inert gas like nitrogen or argon.

Appeals Court Denies Rehearing of Ruling Against EPA Regulation of HFCs

On January 26, 2017, the United States Court of Appeals for the District of Columbia Circuit denied petitions requesting a rehearing by the full court of a decision finding that the Environmental Protection Agency (EPA) had exceeded its authority by regulating the use of HFCs through the Significant New Alternatives Policy program (SNAP).

Energy Performance of Low Charge, Central Type, Dual Stage NH3 Refrigeration Systems in Practice

In the wake of the pending global phase-down of HFCs due to their contribution to global warming, users and owners of refrigeration systems are faced with decisions that at times appear difficult. These decisions relate to whether or not users continue to employ HFC-based refrigeration systems, switch to low GWP synthetic refrigerants or consider future-proof natural refrigerants such as NH3 , CO2 , hydrocarbons, water, or air in their new and/or expanded systems. In this decision-making process, one very important factor is often either overlooked or underestimated. This factor is energy performance—particularly the energy performance of low charge NH3 systems.
