Cold Storage In Summer: How To Keep It Cold!

 

 

Summer is the most challenging season when it comes to keeping your cold storage running – and these days, warm outdoor temperatures can start early in the year and persist well into the autumn. When ambient temperatures begin to rise, problems start to occur…

Why Are High Temperatures So Problematic For Refrigerators And Cold Rooms?

The harder your fridge has to work against the heat, the greater the flow of power and liquid and the higher the risk of sudden breakdowns. Many cold storage units are built for a set temperature range – when this is exceeded, the machinery struggles.

You also run the risk of sub-par performance, even if the machine doesn’t fail outright. Struggling cold rooms can start taking on warm ambient air, decreasing their performance, defrosting items, and spoiling stock as the internal temperature rises.

Sudden fluctuations can also be damaging to refrigeration systems. As temperatures steadily increase, cooling units and heat exchangers have to perform even better to cope. Condensers end up going into overdrive. If the door, piping, and insulation aren’t the right choices for the unit, the cooling system will suffer further still.

The most important factor in keeping your storage sealed, cold, and efficient is good insulation.

If you have excellent heat transfer barriers in place, the engines and pumps refrigerating the cold area will prove much more resilient to higher temperatures, and to temperature fluctuations.

  • If your access or main doors aren’t fit for purpose, you run the risk of air ingress and egress. Hot and cold air exchanging places can weaken condenser performance and cause icing issues as two pockets collide and trap water. A constant escape of cold places much more stress on the temperature regulator and loop.
  • Make sure your doors are sealed with insulation, on auto-closers, and heavy enough to resist outside temperature changes. MTCSS can always advise you on the best solution for your appliance or cold room.
  • You also need to ensure you have good insulating panels in place to prevent temperature exchange and cold air escaping the unit. Summers are becoming more unpredictable worldwide and older machinery and insulation panelling may struggle to respond to rapid shifts in temperature.
  • Older panelling can wear out, too. Thermal loss will lead to everything working harder to compensate for underperformance – resulting in wasted energy and increased costs. Regular checks and monitoring can identify when repairs and replacement are needed.
  • Thermally-efficient panelling can help counter heat ingress. Make sure your unit is fully enclosed by resistant insulation to protect the contents.
  • You can refit existing spaces with suspended ceilings and double-layered insulation if they’re not performing as well as they used to.
  • Keeping your inside temperature stable, rather than exceptionally cold, is often better for long-term cold storage – less stress is placed on the cooling apparatus.
  • Try to limit the time the cold room doors spend open and exposed to the elements, and position your refrigeration units well away from exterior heat
