It’s not enough to tag a defect on a cool room door. On a similar note, panel damage can’t simply be noted in a maintenance log book. A failure to act on such seemingly trivial staff feedback really could have dire consequences, all of which will negatively impact a cool room’s established functions. For one thing, damaged doors and panels leak energy. Then there’s food freshness problem, too.
Chamber Breaches Destabilize Cooling Envelopes
From a practical standpoint, a damaged door won’t open. If it does swing open, perhaps after applying substantial shoulder muscle, it jams open. Clearly, a stuck cool room door requires urgent attention, so a repair engineer is immediately dispatched. But what if the damage is less apparent? A seal is cracked or torn, perhaps. The door works, staff members push their carts up a ramp, and food is loaded. Only, there’s a sudden uptick in expended energy. If this problem isn’t immediately taken care of, the bill payer is in for a big shock when the electricity invoice comes due. Cracked or loose insulation panels create similar situations, unfortunately. Remember, if a refrigerator unit is running constantly, that could indicate a cooling envelope rupture.
Temperature Fluctuations Ruin Perishable Cool Room Products
That’s a proven truism. With a damaged door or loose insulation panel causing a refrigeration unit to perform unpredictably, temperature variations sightly thaw out some of the merchandise. Then the refrigeration cycle recovers, but it swings too far in the opposite direction. Freezer burn is the result of the poorly recovered equipment’s efforts. Again, these are major consequences, and they’re all taking place because of a small seal tear or panel fissure. Seriously, higher running costs are worrying, but that issue isn’t half as bad as a food safety struggle. Sure, a lack of meal freshness is disconcerting, but what if that bad taste becomes something more, something worse? What if the perishable food spoils and causes a nasty stomach complaint?
The implications are disturbing, that’s for sure. Minor door or panel damage in a hard-working cool room can severely undermine its normal operational functions. If that damage is spotted by an observant cart loader or food prepper, the feedback should be interpreted as a wake-up call. Ignored by some, running costs rise sky-high while cooling temperatures fluctuate. It’s like a first domino has fallen. It’s about to hit its neighbour and trigger off a whole series of undesirable causal effects. The energy leaks, temperatures fluctuate, spoilable food spoils, fresh meals go off, and customers leave. Please, if a cool room door or insulating panel is damaged, take immediate action so that those falling dominoes can be stopped.
Let’s cut straight to the chase. Cool rooms don’t just keep flowers fresh, they stop them from blossoming. In effect, the cold acts like a pause button. That means, should a large delivery of floral merchandise arrive at a shop, the staff can create a biological buffer for themselves. Instead of the merchandise opening, according to some biological imperative, a temporary halt is placed on its growth cycle.
Cool Rooms Are Floral Time Machines
Or maybe they should be described as stasis chambers, like the suspended animation devices found in science-fiction movies? Whatever the label, their purpose is clear. By taking a product that has a finite lifespan, by placing that time-sensitive organic inventory in a chilly cool room, a shop owner gains a kind of superpower. They can suspend a flower’s blossoming cycle. Okay, this power is temporary, for the plants are still aging, but they’re now ripening at a very slow pace. Stabilized and locked into the budding stage, flowering petals won’t put in an appearance until a florist is ready to make an arrangement.
Without a Cool Room
Sure, the room is
equipped with a refrigeration unit, but the cool breeze blown from that
ceiling-mounted appliance isn’t meant to freeze anything. There goes the
suspended animation analogy, but that’s okay. No, there’s a late autumn chill
inside the glass-walled room, not a flower-killing winter frost. Without that
cold, a truck-full of budding plants would flower after a few days of storage.
Even the ambient warmth in a shop office would be enough to trigger the
blossoming stage. Imagine the scene, with every single flower showing off its
petals over the span of two or three working days. For the shop staff, the
colourful display would be magnificent, but no one else would get to enjoy that
flowery scent or the richly-hued petals, for that matter. As the floral
arrangements came together, they’d wilt and spoil. What’s left to say?
Successful flower shops won’t enjoy their profits for long if their
arrangements leave the shop looking lifeless and desiccated.
Suffice to say, flower shops need cool rooms. Those sealed little rooms keep flowers rosy fresh and fabulous. Of course, since they’re part of a shop’s overall appearance, metal panels and opaque insulants are out. Instead of those energy-saving wall panels, glass-walled plates and sliding doors are given preference. The polished glass shows off a just-blossomed arrangement while the budding plants remain concealed on a second or third row. Why, there’s even a separate work area in there, where arrangements are stored until they’re ready to be delivered, en masse, to a wedding or large event. Basically, this is a flower shop’s buffer area, and it’s that buffer that gives a shop owner power over a flower’s growth cycle.
Starting with an obvious observation, the team members who are responsible for taking apart a coolroom need to protect themselves. Granted, if this is a newer construct, it’s likely been designed to come apart easily. In other words, it’s modular. That being said, sharp edges will become exposed as the chamber breaks apart. Wear protective gloves and observe the following guidelines.
Electrically Isolate the Equipment
There are live electrical circuits humming quietly inside operational coolrooms. Even when the refrigeration equipment isn’t powered, perhaps because the thermostat isn’t active, there could be a dangerously high electrical charge nearby. Remember, this equipment requires a moderately high amount of power. Moreover, the chamber likely has lots of exposed metal parts. If an electrical shock does occur in here, it could prove fatal. Always safely isolate the circuits. Turn them off at the fuse board, pull the fuses, or lock down the circuit breakers. Even after all of those actions have been taken, a professional refrigeration technician will still want to test the circuits to make sure every live wire is safely depowered.
the Refrigeration Equipment
It’s not hard to relocate the electrical wiring.
In point of fact, it might just be cheaper to rewire the whole thing. If the
wiring is kept, check the insulation for any abrasive scratching. If the wires
are damaged, they can’t be used again. Anyway, even while taking the
possibilities of wiring damage into account, this is still a straightforward
procedure. For the refrigeration unit, well, things can get a mite more
complicated. For starters, there’s the refrigerant to deal with when breaking
down the gear. A dismantling or decommissioning process can’t begin by ripping
the gear out of its ducting. No, the fluid has to be depressurized and
discharged. There are refrigerant recovery protocols to observe, plus the
storage/transferring equipment to purchase. Then, if this really is a
decommissioning job, there might be an environmentally harmful fluorocarbon
load to safely dispose of, as regulated by a nationally accredited ruling body.
In order of personal and environmental hazards, the electrical dangers come out on top. They’re more immediate, for high electrical currents can kill instantly. Next, an environmental hazard exists as a charged refrigerant load. The fluid needs to be discharged and valves need to be sealed. The recovery procedure clearly requires the services of an expert engineer. This is no job for an amateur. Finally, mechanical dangers are easier to pinpoint. Sharp edges can cut sensitive skin while heavy walls can crush limbs. Incidentally, unforeseen hazards are always lurking. Wear a breathing mask, just in case the wall insulation contains dangerous fibres. That mask will also provide additional protection, should dangerous bacterial spores be concealed in those wall panels.
coolroom’s layout is optimized, yet the equipment’s still drawing way too much
electrical energy, something’s still not right. Odds are the refrigeration unit
has some kind of a performance frustrating issue. Even more frustrating, this
issue is ongoing. It’s not getting any better, and it won’t until someone
tracks down the energy siphoning cause. Calling in an expert service engineer,
that pro-worker should head straight to the equipment coils.
Obstructed Refrigerator Coils Cause Energy Losses
speaking, the icy build-up hampers coil efficiency. Perhaps there’s excess
moisture coming off of a row of frozen meat, or maybe the region in which the
coolroom resides is naturally humid. Whatever the reason, the excess moisture
condenses when it comes in contact with the evaporator coils. And it’s not
going to stay that way for long. After the condensate forms, it freezes. Over
and over, this cycle repeats until a thick layer of ice impacts the cooling
mechanisms heat transferring functions. Meanwhile, over on the condenser coils,
dirt and debris have a similar effect on the heat release stage. Without a
fully exposed condenser, the refrigerant can’t cool and condense efficiently.
Coil Restoration Methodologies
It’s nice to know that a little warm water and soap can restore a complicated assembly of technologically advanced electro-chemical parts to their functional best. Instead of replacing a hard to get at compressor unit, the servicing team just washes the dirt off of one coil while someone else removes the ice from the second set of coils. Only, hold on, it’s not quite that straightforward. To really restore heat transference performance, elbow grease isn’t enough, not even with a bucket of hot water. In reality, when refrigeration companies offer a coil restoration service, they’re talking about powerful steam equipment and cleaning agents. Applied as a multi-stage system rejuvenation process, steam and non-corrosive cleaners soften and-de-bind the ingrained dirt.
There’s outside work to be done. The vents and filters require cleaning. If they’re filthy, a few replacement parts will soon fix things. That same approach won’t work on the condenser coil. Likewise, after the ice has been carefully melted off the evaporator coils, there are still traces of muck and gunk coating those exposed parts too. A run-of-the-mill coolroom servicing company might try that warm water and soap approach, and they might even have limited success. Stepping up to the next level, a genuine coil restoration assignment uses proprietary coil cleaning techniques, which may or may not include steam ablation technology. With coil performance back to its functional best, advanced auditing and data collection instruments make sure coolroom efficiency is maximized.
to popular opinion, refrigeration services don’t always place a heavy focus on
cooling equipment. Admittedly, that’s their raison d’ê·tre, their main role in
life, but this is a profession that covers many different engineering
disciplines. Why, there are even times when C & M Coolrooms technicians
find themselves repairing or replacing heating cables.
Where Are The Heating Cables?
wires of this type can be found in several locations. Before going any further,
however, these aren’t true heating elements, they are radiant fractional
amounts of thermal energy. For example, a cold concrete floor could crack
because of the minus 20°C temperatures inside a deep-freeze unit. Worse still,
there might be groundwater under the concrete. It’ll freeze, the ice will
expand, and the concrete will crack again. Door seals also need wired heating.
Trace heating wires thread their way around door frames so that a rime of ice
doesn’t cause the door to stick. Last of all, heating cables can be wrapped
helically around all sorts of fittings, including ducts and pipes.
Replacing Damaged Or Aged Thermal Cabling
amounts of energy are enough to stop a floor cracking or prevent a door from
accumulating frost damage. Unfortunately, just like any other equipment
fitting, these insulated electrical wires do have a limited lifespan.
Admittedly, it’s not going to be easy to replace underfloor cables, not unless
they were installed in tubular conduit. One solution to this issue is to
replace the underfloor cables with rubberized mats. The knobbly pattern on
those rubber sheets insulates the floor while also acting as a slip prevention
aid. For the broken door seal, a replacement heating cable is far easier to
Portal Frame Wiring Replacement
The technician turns
off the power, as the circuit may still be live, even though it’s no longer
functioning. A continuity test with an electrical multimeter should be used
next. If the circuit is damaged, the tech puts on a pair of gloves, exposes the
wire, and carefully removes it from the door edges. A replacement cable, one
that uses the same electrical specs, is now substituted for the damaged heat
tracing. Remember, the lip of the door may seamlessly connect to the unit’s
insulation panels. If that’s the case, a C & M Coolroom technician should
be called out to carry out the work.
Interestingly, there are new underfloor options on the horizon. Heating cables are still clearly the superior option. Only, they can be impossible to replace. One solution involves running them through buried metal conduits. A second idea is to use a piped fluid, such as glycol. Transporting trace amounts of heat into the floor, there are no moving parts to fail in a fluid-based underfloor heating system.

Somewhere out there, a custom-built walk-in freezer has rejected its cookie-cutter layout. Elsewhere, perhaps in a remodelled supermarket, a designer has used out-of-the-box design practices to construct a glass-doored coolroom that looks appealing. Behind the steel and glass framing, beverage stockers are working unobserved. Clearly, singular designs, custom-designed coolrooms satisfy every conceivable client stipulation. However, for every unique system layout, an equally unique problem can develop.
Avoid A Super Streamlined Layout
Perhaps the cold room is going up in a smaller than average piece of floor space, or some interior designer believes the time has come to develop a super-skinny walk-in unit. Well, coolrooms are airy spaces for a reason. They use that space to maximize system airflow and ensure every item has access to its own stream of chilled air. A custom-designed interior layout is welcome, but the visually appealing stylings cannot take precedence over the airflow factor. Of equal importance, stylish doors and slender system air intakes are allowed to assume tailored profiles, but that shape cannot interfere with their functions. A sealed walk-in freezer door keeps its interior safely chilled and energy-efficient. Likewise, an air intake panel doesn’t experience the custom-designers’ scalpel, not in a way that would impair its air channelling features.
Seeing Through The Blank Palette Illusion
It’s easy to make this mistake. Someone goes inside a typical walk-in unit and sees its featureless build. It’s a blocky construct with a concrete floor and a powerful refrigeration unit. Completing the design, a sealed access portal and a thermostat deliver a spartan but functional build. Surely, if a designer was let loose, all kinds of build factors could be configured to suit a particular application. To a point, that’s an accurate statement. But the tailoring work can’t overrule a key set of engineering-oriented design factors. Alter the dimensions and shape of the space, but don’t obstruct airflow by adding too many twists and turns. Always adopt a form follows function design philosophy.
To label those basic factors, let’s break a custom-designed build down. Dimensional changes are feasible, but the alterations can’t impact safe airflow distribution levels. For tailored doorways and venting/inlet requirements, the refrigeration unit needs access to an uninterrupted volume of outdoor air, and the door seal must maintain this carefully controlled thermal low. Likewise, a custom-designed bank of insulated wall panels can gain an embossed pattern of some kind, but that aesthetic appeal can never be more important than the composite materials that insulate the walls. At the end of the day, functionality isn’t just a convenience here, it’s a hygiene safeguarding guarantee. That feature can’t be undermined, not even by a custom-designed layout.
