WhatSeveral temperature regimes in one shop

Food retail refrigeration means running several temperature regimes simultaneously in one building: chilled display around +2 to +4 °C, frozen display at −18 to −21 °C, back-of-house cold and freezer rooms, and ice for fresh fish and produce. Systems are either centralised — one machine room feeding the whole shop through long pipe runs — or distributed, with self-contained plug-in cabinets.

WhoWho buys retail refrigeration

Retail chains with a standard store specification, franchise operators, convenience store developers, and the refrigeration contractors who install and maintain the estate. Chains buy to a repeat specification across many sites, which makes consistency and spares availability worth more than unit price.

WhereWhy small formats changed the equipment

Worldwide, with the fastest growth in small-format convenience and discount stores. The small format has changed what gets bought: it favours plug-in self-contained cabinets over central plant, because there is no machine room and no site pipework to commission.

WhenOpenings, remodels and refrigerant deadlines

At new store openings, at remodel cycles that typically come around every seven years or so, and — increasingly the largest driver in regulated markets — at refrigerant transition deadlines that force replacement of otherwise serviceable equipment.

WhyThe store's largest controllable cost

Refrigeration is normally 40–60% of a supermarket's total electricity consumption, which makes it the single largest operating cost the store can actually influence. On top of that sits regulatory pressure: high-GWP refrigerants such as R404A are being phased down, pushing new installations towards R290 hydrocarbons for self-contained cabinets and transcritical CO₂ for central plant.

HowCentral packs versus plug-in cabinets

Decide the architecture first, because everything else follows from it. Central packs give the best efficiency at scale and keep heat and noise out of the shop, but need a machine room, long pipe runs and a large refrigerant charge that will leak over time. Distributed R290 plug-ins eliminate field pipework and leakage entirely and are far quicker to install, at the cost of rejecting their heat into the sales floor — which the shop's air conditioning then has to remove. For anything mid-sized, model both before committing.

Questions buyers ask

Central pack or self-contained plug-in cabinets?
Central packs are more efficient at scale, keep compressor heat and noise out of the sales floor, and suit large stores — but they need a machine room, long field pipework and a large refrigerant charge that leaks over the system's life. Plug-in R290 cabinets have no field pipework at all, install in a fraction of the time and cannot leak a large charge, but they reject their heat into the shop. Small and convenience formats increasingly go plug-in for exactly these reasons.
Why are supermarkets moving to R290?
Propane has a GWP of about 3 against roughly 3,900 for R404A, and it is thermodynamically more efficient as well, so it answers both the regulatory and the energy problem at once. Its constraint is flammability, which caps the charge per system — which is precisely why it suits small self-contained cabinets rather than large central plant.
How much of a store's electricity does refrigeration use?
Typically 40–60% of total consumption in a food store, far ahead of lighting or air conditioning. That concentration is why refrigeration efficiency measures — variable-speed compressors, night blinds, doors on chilled cases, floating head pressure — pay back faster in retail than almost anywhere else.
