The Catch 22 of R22 Replacements

If you’ve recently googled “it’s almost 2020 and I still have R22” then hopefully this article grants you some timely insights. The world of refrigerants has become much more complex since you could refer to your refrigerant as “Freon” and not make an embarrassing social blunder because you were actually using a halogenated hydrocarbon and not a fluorinated hydrocarbon mixed with an unsaturated fluorinated alkene.

Clean Evaporator Coils Reduce Energy Expenditure, Lower Costs

Numerous factors can contribute to decreases in a refrigeration system’s energy efficiency, not the least of which is its cleanliness. Much of the time, when facility operators see a facility’s efficiency drop, they believe that indicates they must replace the systems with larger units, when in fact, they often simply need to clean the systems they’re currently using - particularly the evaporators.

Understanding Bond Yields and the Yield Curve

When it comes to investing in bonds, one of the first factors to consider is yield. But what exactly is “yield?” The answer depends on how the term is being used. In the broadest sense, an investment’s yield is the return you get on the money you’ve invested. However, there are many different ways to calculate yield. Comparing yields can be a good way to evaluate bond investments, as long as you know what yields you’re comparing and why.

Pre-emergency preparedness

Are you prepared? I think most of us think we are LESSON prepared, at least to deal with whatever we expect to happen. The trouble is that often what we come up against is not something we expected – therefore we are not prepared to deal with it. For ammonia refrigeration whether a system has 400 lbs. or 40,000 lbs. (or more) we should do pre-emergency planning and training.

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.

Energy and Function Analysis of Hot Gas Defrost in Ammonia Refrigeration Systems

Traditionally one of two methods for controlling drainage of the evaporator during hot gas defrost is used: pressure control, which keeps the pressure in the evaporator constant during defrost, or liquid drain control, which uses a float valve to drain condensed liquid from the evaporator. Each method’s energy consumption is quite different, as the pressure-control method bypasses a certain amount of hot gas during the defrost period.
