Benefits of Energy Saving Audits for Freezers and Coolrooms

08 April 2016

While it may sound like a wild term, one that unwittingly connects financial earnings to cooling equipment, energy audits actually represent a purposeful methodology. The study analyses freezers and coolrooms, inspecting every system in the unit for energy loss sources.

Building Your Efficiency Roadmap

Every business venture survives on its wits, but financial acumen is a little harder to account for when large equipment enters the equation. An energy saving audit equals an opportunity to look at the big picture and see where wasted energy is escaping. Actual energy expenditure is calculated on an electrical scale and converted into mechanical and cooling assets, at which point you gain a clarified image of any disparity. In other words, you reduce kilowatt-per-hour consumption while keeping spoilable food and beverages as cool as ever.

Improved Cooling Envelope Integrity

Freezers and coolrooms are two different storage beasts. In the case of a freezer, you enter an actively frozen environment, a place where poorly insulated panelling can often be seen with the naked eye. Coolroom containment offers a more subtle through no less important containment solution. The food is kept fresh and ready for processing and cooking. Beverages are chilly but still fluid. An energy audit is a very accurate time-in-motion study, one that can differentiate between imperceptible thermal changes and trace those changes to their source. The result is a fully formed thermal envelope, even when that envelope is formed around the around-zero environment of a coolroom.

Laser-Like Resource Management

If a cooling unit is costing the commercial establishment bundles of cash, the temptation is to replace everything and eventually catch up when the savings start rolling in. The analysis procedure cuts the fat from the bones in this strategy by identifying exact loss points. Indeed, a professionally conducted audit can find flaws in the compressor assembly, detect insulation problems, door leakage issues, and much more. Thus, only the energy-costing parts require repair or replacement.

Commercial-grade cooling solutions are incredibly energy intensive. Contemporary Energy Star (www.greenrestaurants.org) guidelines reduce much of the losses associated with these essential food-preserving chambers, but the subject is still clouded by conflicting mechanical and electrical factors. Even the actions of the staff have an effect on the results of the audit, with some incautious staff members leaving freezers and coolrooms exposed to the open for extended periods. The study documents this staff-related issue and all mechanical loss points, creating a loss plan that can be resolved with maintenance, newly incorporated procedures, and some repair work.
