Based on cold chain technology, this store solution saves energy and reduces greenhouse gases by half

Supermarkets and convenience stores, which must keep foods at exact temperatures while displaying them, are moving from advanced countries to developing countries. As they do, electricity consumption and the quantity of transported food are increasing dramatically. Energy and environmental problems have become global issues, necessitating store management solutions which save energy and are gentle on the environment.

In most supermarkets, freezing and refrigeration equipment accounts for approximately 40% of the electricity consumption of the entire store. Panasonic has focused on developing a store solution based around this freezing and refrigeration equipment, essential to the “cold chain” which continuously maintains foods at their proper temperatures.

An invisible wall to seal in the cold

Everyone knows that opening and closing the door on a home refrigerator/freezer as little as possible is a great way to save energy, but stores have to keep their showcases open for customers to be able to access the products.

Panasonic has been able to fulfill this contradictory requirement with its unique technology, the “Double Air Curtain.” It seals cold air into showcases with an “invisible door,” protecting the freshness of foods inside while minimizing electricity consumed.

Panasonic has also developed the “New Temperature Maintenance System,” maintaining the perfect temperature by offering protection from by fluctuations in the outside air, and preventing energy loss from overcooling. On top of all this, by switching to LED lighting inside showcases, and by utilizing energy-saving glass doors, the entire showcase is expected to use significantly less energy.

“Environmentally friendly” and “energy saving,” side-by-side.

Widely used as refrigerants in freezing and refrigeration equipment, CFCs and its alternative HFCs both have negative impacts on the environment. Developing natural refrigerants that will lower the potential for global warming while reducing negative impact on the environment, has become crucial.

Among natural refrigerants, CO2 is non-toxic and non-flammable, which is excellent from the perspective of safety. But compared to systems using HFC’s, CO2 systems have a tendency to be high-heat and high-pressure, making their utilization in a refrigeration and freezing equipment difficult.

Since 1997, Panasonic has been working to turn this common knowledge on its head. By utilizing high-pressure-resistant compressors, refrigerant cycles utilizing split heat exchangers which were developed for cold-region EcoCute (CO2 heat pump hot-water supply system), miniaturization of refrigerant pipes, and optimization of pitch, Panasonic has developed non-Freon freezer units which maximize the unique capabilities of CO2 as a refrigerant, while also saving energy.

Achieving energy independence in a single unit

Saving energy and reducing environmental impact for a whole store requires more than just adoption of heating and cooling technology; it also requires reduction of energy consumption through air conditioning and the introduction of LED lighting throughout the store. On top of this, by adopting solar energy generation through solar panels, stores can produce their own electricity, enabling entire store management systems to save energy.

By providing simultaneous energy saving and energy creation, Panasonic is providing a concrete contribution to solving the environmental issues brought about by accelerating energy consumption in developing countries.

Store Controller reduces output of greenhouse gases by half

In order to get even more performance out of energy-saving refrigeration and freezing equipment, air conditioning equipment, and lighting, Panasonic’s “Store Controller” connects and manages a store’s showcases, freezers, air conditioning equipment, and lighting, all from a single unit.

By automatically adjusting its settings based on outside temperature, brightness, and more, the system can improve energy savings. With these adjustments, an entire store’s greenhouse gas output, converted to CO2, can be reduced to less than half.
