Grocery closed for faulty refrigeration

Published August 7, 2005

Value Food Center at 344 E. 63rd St. remained closed at week’s end after being shut down on Monday by inspectors who discovered that nearly all of the store’s refrigerators and freezers were failing to keep food at safe temperatures.

The Health Department ordered that about 20,000 pounds of refrigerated and frozen food be thrown out, officials said.

Inspectors also ticketed the store for an unsanitary meat grinder and other food processing equipment; waste-water backup from a sink; mouse feces in a storage area; an exit that allowed rodents and insects; and an outside garbage container that did not close properly.

Mercedes are Hot News for WR Refrigeration

One of the UK’s leading refrigeration contractors is turning up the heat on its rivals after taking delivery of its first Mercedes-Benz vans.
Following successful trials of two units within its branch network, Finnish-owned WR Refrigeration is buying 50 Vito 109CDI Compacts for operation by its service engineers.
They are the first of 250 Mercedes-Benz vans to be supplied by Birmingham dealer Gerard Mann Commercials, which will replace the company’s current French brand fleet over the next 18 months.
“We needed a vehicle to carry our refrigerant cylinders and refrigeration machine parts,” says WR Refrigeration’s Finance Director Andrew Robinson. “The 2.7-tonne Mercedes Vito is a more attractive proposition than our existing vehicles as it offers an extra 200 kg of payload. This means more stock can be loaded; yet the van is still relatively compact and manoeuvrable.
“As a result our engineers will be better equipped to solve a wider range of problems on-site and, therefore, offer our clients a quicker, better and more efficient service at the first visit, with less inconvenience to their operations.”
WR Refrigeration, which has head offices in Leicester and a network of 27 branches throughout the UK, provides refrigeration services principally to national food retailers, such as Wm Morrison, Iceland Frozen Foods, Tesco and Waitrose.
Its business comprises a 24-hour service division and a sales division, which provides design and project management support. The company was recently acquired by the international refrigeration group, Huurre, of Finland, and now employs in excess of 500 people, including more than 300 service and installation engineers.
Sleek and stylish, WR Refrigeration’s Mercedes Vitos are air-conditioned and ply-lined, with steel bulkheads. They also bristle with active safety features, including the remarkable ESP anti-skid program. The vans will be maintained by the most conveniently located Mercedes dealers.
Mr Robinson adds: “The financial aspects of the deal were certainly attractive but the real key to Mercedes-Benz winning the order was the fact that our engineers were so overwhelmingly positive about the Vito’s capabilities, performance and comfortable, car-like driving environment during the trials.”

Predicting Compressor Failure

Good Housekeeping

The most important factor in predicting compressor failure can be found by the cleanliness of the Oil. Virgin oil is clean, nonconductive and the primary insulator against voltage leakage to ground. Equipment manufacturers for the most part put together very clean systems and when properly maintained can last a long time. Service technicians do their part by taking all the right steps when opening systems for repair. But despite every precautionary measure taken by the manufacturer and service company, changes in the oil can occur beyond our control.

Refrigerant/Oil will combine and breakdown into water, acid, acid byproducts along with metal and metallic salts from corrosion and wear. These compounds will be found dissolved in the Oil Phase. The protection one would assume from driers is limited. Driers reach an equilibrium at about 20% capacity rejecting further moisture adsorption. The point at which drier material no longer serves to protect a system can be linked to the gradual increasing amounts of contaminant build up in the Oil.

Tools to predict changes in compressor oil have been around for the longest time, however you seldom see them on a service truck. My favorite has been the Megohmmeter, but how many technicians own or actually use a megger. Probably less than 1%.

Lower on my list is the compressor oil acid test. The acid test is no great predictor. A positive acid test only tells you, “your oil has no viscosity, your driers are filled to capacity and your compressor is nearly wasted”. Few technicians really understand that acid build up is the consequence of years of neglect. Besides how many technicians are willing to do an acid test on a hermetic compressor. Not in my lifetime. Maybe if the semi has a crankcase drain plug. But the results of an acid test won?t tell me if a tornado is coming through town; it will only tell me the tornado has hit, and the town is leveled.

A good housekeeper wants to keep his customers running trouble free. Favorable referrals from satisfied customers build a foundation for every successful contractor. The housekeeper who keeps sweeping dirt under the rug will eventually build a pile high enough to smell.

Remodeling the Kitchen

We set out to develop an easy oil test that would have the same predictive value as the megaohmmeter. The oil test needed to detect elemental amounts of contamination in the bulk oil. In order to meet our goal, we looked for any new promising technology.

Everyone is familiar with dyes that sense pH - the infamous acid test. However, very few know about dyes that sense voltage (electrochromes), or dyes that sense light (photochromes), and there are also dyes that sense heat (thermochromes).

Duracell uses a green voltage indicating dye as their battery tester, a very successful product innovation.

A German mirror manufacturer developed a remarkable light sensitive dye. The dye darkened under bright sunlight then became more transparent as light diminished. First used on sunglasses and later used to coat rear view mirrors on luxury cars.

The science of dye chemistry was open to investigation in light of many new discoveries.

This Old House

Dyes that sense moisture have been in liquid line sight glasses for many years, but these dyes are not all they are built up to be. They have too broad a range to be practical or even remotely reliable. If you get a ton of water in a system, the color will change on the sight glass, but for the most part, your system can be very wet and still register a dry color reaction. Remember, with sight glass moisture indicators, you are relying on a dye technology developed before the television.

The New Yankee Workshop

Recently, a dye chemist was experimenting with coloring hazardous solvents. The aim was to identify solvents by their color. Sort of like why we color code Refrigerant tanks. He dyed some pure acetone red, as the acetone adsorbed moisture from the air, the dye began to darken to violet. Another moisture sensitive dye? Not quite, he was observing the acetone lose dielectric strength.

Hence the discovery of a brand new class of indicator dyes.

Mineral, Alkyl benzene and Polyol Ester oils all must have a very high dielectric strengths in order to insulate the compressor windings from voltage leakage to ground. It does not take much moisture to decrease the dielectric strength of Refrigeration Oil. Add some acid or dissolve a little metal in the oil and you?ve got a liquid conductor. We perfected dye derivatives which will produce color shifts at the slightest change in oil purity.

We initially calibrated the color chart of our Oil Test against readings obtained by a megaohmmeter on working compressors. However, when we compared the megger readings against a chemical oil analysis, we found a lot of fault in our old reliable megaohmmeter. It was obvious, my favorite instrument did not register changes in the oils composition quite as good as once thought. The megaohmmeter was registering good Oil in situations where we knew, from a chemical assay, the Oil was bad. The Oil Test was recalibrate to more closely match the laboratory results.

Better Homes than Yours

If you are a contractor who regularly sends out oil samples for wear analysis, you will find our oil test correlates accurately with the lab report. Furthermore, with our tester you get your results right on the spot.

We realize the majority of contractors never look to the oil for diagnosing system operation. The lack of interest lies in the hassle of obtaining an oil sample. With our test you simply “milk” the suction line for one drop of oil. All too easy?Whenever you can provide your present or potential long-term customer added service, you gain an important leg up on the competition.

For further information read our Checkmate Manual. The manual will explain how to use the Oil Test and interpret the results for corrective action.

Addendum

We tried a New Room Addition

The same dye derivatives used to indicate bad compressor oil; could also be used as a contamination indicator for vacuum pump oil. By adding a certain violet dye to a stock vacuum pump oil, the oil will eventually turn dark blue after about 2-3 systems evacuations. Great, an intelligent oil which tells you when it?s collected to much gunk and needs to be changed. Problems arose thereafter; since dyes that are capable of dissolving in oil tend to be acidic.

Corrosion and seal damage was prominent after a couple hundred operation hours. We could stop the metal corrosion by boosting the oil with inhibitors and antioxidants, but the seal shrinkage proved far too extreme to overcome.

We have postponed our new room addition for now, but will redraw some plans later.

Do You Believe in Magic?

The Truth about all those Miracle Oil Additives

Just watched a pretty good magician work a small carnival at our local elementary school this week. The magician had all the small folks believing the power to transform and make things disappear was contained in black wand. At the end of the show you could purchase a wand with the same magical power complete with instruction video for only $19.95. Now that?s a real bargain compared to the secret potions our industry is being hammered with on the Internet, some Radio, TV and at local HVACR wholesalers in the gulf region.

Our product evaluation took place about ten years ago when we were approached to distribute a new compressor oil additive having remarkable chemical enhancements. The additive was guaranteed to reduce friction by molecular bonding to all internal moving parts. As mechanics we realize less friction will give us a better running motor, and these molecules electrically bonding to metal really sounds good. The answer to mechanical powered motion the world has been waiting for.

Now I do not have all the answers on the way things work or how the magician performed all his amazing tricks, but the information I shall provide is worth considering before you part with your hard earned dinero. Or better yet, before you unknowingly sell a bombshell to one of your trusted accounts.

The products I am referring to are the Chlorinated Hydrocarbon Lubricants, a.k.a. Chlorowaxes, Chlorinated Paraffin’s, Polarized Additives. After almost ten years of hibernation there back again. These oil additives demonstrate incredibly well under just the right conditions.

The Infamous Bearing Under Load Test

The bearing load test is the most popular demonstration unit. A bearing is mounted on a motor shaft and a hand held fulcrum lever is used to apply metal-to-metal contact on a spinning bearing surface. Without a layer of oil the bearing smokes and squeals. When oil is applied onto the spinning bearing, the grinding stops and everything rides smooth. That is until the pressure applied by the fulcrum lever is increased to a point exceeding the pressure limitation of the oil. Next, the bearing surface is properly cleaned in preparation for the application of our miraculous Chlorinated Oil. The bearing is stressed to near maximum fulcrum pressure but the bearing runs quiet and smooth showing the superior lubricating strength of the Chlorinated Oil.

Convinced me the first time I witnessed this demo at a trade show, convinced a lot of people. That is until a little knowledge comes to light. The bearing pressure test can be beat with many materials. Common bar soap, Ivory , for one, and believe it or not, Hydrochloric Acid. Yes, Hydrochloric Acid molecules bond to protect metal surfaces and reduce friction for quite a long time, that is, until it starts dissolving the metal.

The Plot Thickens

The Chlorinated additives are marketed with a basket full of wondrous claims. Lower head pressure, quieter running compressor, lower energy consumption, cleaner more efficient heat transfer just to name a few. Maybe we should actually add the Chlorinate to a system in the field to see if we can duplicate those inflated claims of a 25% boost. Well, we did. A five ton R-22 packaged A/C system received the recommended dose of 10 ounces of Additive. The cost for the treatment was a mere $600.00. Better cooling, more cooling, less energy use, we should easily recover our investment. Says so right on the bottle.

We injected the Chlorinate Additive, and within a few minutes, the compressor ran noticeably quieter. The head pressure dropped about 15 PSI and the amp draw fell 5%. WOW?

This is it, we were sitting on a gold mine. This stuff will make us $$$$ millions. Should we inject more additive to see if we could really peak this system to even better performance?

Wait a minute, hold your horses partner, I have seen this symptom before, recalling an incident back in my service days when I screwed up a customers walk in box by mistakenly adding R-12 to an R-22 system.

The Magicians Trick is Exposed

When a compound having a low vapor pressure (such as R-12) is added to a system containing refrigerant of a higher vapor pressure (R-22), the bulk system pressure will fall. Charge the same R-22 system with R-11, and the head pressure will dive faster than a lead weight. So will the amp draw, compressor noise, and system cooling capacity as measured by the rise in supply air temperature.

We blew the experiment. We forgot to take the temperature of the evaporators supply air before injecting the Additive and watch for any rise in supply air temperature thereafter. It appears that the Chlorinated Lubricant acts upon the refrigerant mass inversely, we could not show proof from a baseline measurement because we were unprepared. Who would have known?

The Magic Wears Off

After two months of unit operation we hooked up the gauges, thermometers and an amp probe to see if any factors had changed. The first condition noted was the compressor sound. Nothing clanking or grind just a normal sounding compressor not nearly as quiet as right after the additive was first injected. The amp draw had returned to normal, and the generous head pressure drop almost completely recovered to former levels. The air temperature coming off the supply side of evaporator was still lagging but acceptable.

I am a fan of oil testing so we decided to drain enough fluid to obtain a complete chemical profile. As everybody knows, getting 100 cc of oil out of a 5 ton hermetic is no joy.

The oil would reveal what changes, if any, have taken place. The oil was dark brown, very thin and fuming with a distinct odor. Lab analysis indicated high acidity, chlorine, tons of dissolved metal and the viscosity had completely dropped out. Granted, we did not do an oil test before we used the Additive, but a four year old system virtually untouched should never have oil in this bad of shape.

The Chlorinated Lubricant obviously became unstable because of heat, compression or shear. The Chlorinate fueled hydrochloric acid production. We are not talking trace amounts of acid in the oil: we are talking mega acid.

We put our system back on line with new oil, refrigerant and liquid line drier. Unfortunately, we lost our compressor about two years later to a real nasty burn-out. Could have just been the compressors time to go; could have been the real hot summer; could have been our thermostat jockeys. Could have been from the damage caused by the Additive, but not likely, says so on the bottle. Maybe we could call the Additive manufacturer and threaten law suit unless he pays for our compressor; can?t do that either says so on the bottle. Besides, the original company we were dealing with had been acquired by someone else and that someone else got legal immunity for any liabilities of the previous owners, says so in their letter.

Houdini Never Died

Our investigation was conducted on a product peddled ten years ago. We have not tested any of the new bees of today. We?ve studied their theory, promises, lavish claims and patent references. The language used to promote the present day Additives are carbon copied from the literature of the old.

Marketing gimmicks never die; they just undergo resurrection. Hopefully, the second coming will be the final act.

I for one will not miss them. Don?t take me wrong, I enjoy watching magic. But face it, magic is no fun after you?ve discovered how the trick is done.
