Supermarket refrigeration

It is estimated that refrigeration accounts for almost half of the energy consumption of a typical grocery store in the US. As ambient temperatures continue to rise globally, so will the cost of cooling with the direct expansion (DX) systems that most supermarkets rely on.

SWEP BPHEs for supermarket refrigeration

SWEP has a wide product portfolio for split, cascade and transcritical CO₂ booster systems for supermarket refrigeration. SWEP brazed plate heat exchangers enhance the efficiency of these systems, reducing both costs and emissions.

Precise temperature control

Commercial refrigeration systems have strict temperature parameters. They must be maintained at either:

+6 to 0 °C in medium-temp cold units and rooms
· -18 to -24 °C in low-temp cold units and rooms

To achieve this level of cooling, most retail food chains rely on multiple-rack DX refrigeration systems that utilize high-GWP synthetic refrigerants.

An alternative to synthetic refrigerants

The synthetic refrigerants used in traditional DX systems are costly, both in terms of their high initial purchase price and in terms of the risks they pose to the environment if leaked. Leaked synthetic refrigerants are a significant source of direct greenhouse gas emissions. Multiple-rack DX systems also contribute indirectly to greenhouse gas emissions through excessive energy consumption.

TRANSCRITICAL CO₂

Low cost, low GWP

CO₂ is a low-cost refrigerant that delivers high-efficiency cooling. Transcritical CO₂ booster systems are an effective, cost-saving solution that makes it possible for system designers and owners to use natural refrigerants in a retail context. They save both money and energy and even make it easier to reclaim waste heat from the system.
