All you have to do is open the door… Hongcheon-gun’s first year of electricity ‘Jul-Jul’

Let’s see the picture above. These are common refrigerators in convenience stores.

On the left is an open refrigerator. Milk, sausages, and lunch boxes are mainly displayed.

On the right is a door refrigerator. It usually holds beverage merchandise.

■ The refrigerator with the door open is cooler

The difference between ‘with and without’ the refrigerator door is huge.

There is no need for complex explanations, right? You can think of the bruises that come back when you don’t close the refrigerator door at home.

An open refrigerator requires strong cooling as it does not have a door. Otherwise, it is difficult to meet the proper temperature for food storage.

The Korea Consumer Agency and the Ministry of Food and Drug Safety randomly surveyed 60 convenience stores in the city.

We checked 829 foods (534 open and 295 door) stored in open and door refrigerators, and there was no case of food spoilage due to incorrect refrigeration temperature. That’s fortunate.

however… Should I just be happy?

We compared the average temperature of food stored in each refrigerator.

□ Door Refrigerator: 7.7℃ / Open Refrigerator: 6.9℃

I thought the temperature would be higher in an open type refrigerator because there is no door, but in fact it was the opposite.

It’s possible because it kept the cold so hard. I set the refrigeration temperature lower.

In the unlikely event that a problem arises after selling spoiled food, it is a situation where you have to bear a much bigger social condemnation than before.

Rather than taking the risk of an unnecessary incident, you choose to lower the refrigerator temperature by 1 degree.

It’s nice to have food safe with the fridge door open, but nothing comes for free.

The electricity consumption is significant. If it was a door type refrigerator, not an open type, it is electricity that you do not need to use.

How much electricity is wasted? The Ministry of Food and Drug Safety has calculated.

By replacing one open refrigerator with a door type, you can save 1,511 kWh (kilowatt hours) of electricity per year.

There are about 52,000 convenience stores nationwide. Assuming that all open refrigerators here are replaced with door type refrigerators메이저놀이터approximately 730,403 MWh (megawatt hours) of electricity can be saved annually.

This amount is enough for the residents of Hongcheon-gun, Gangwon-do to use it for a year .

As of June this year, Hongcheon-gun, Gangwon-do has a population of 67,632. As of 2021, electricity consumption per capita is 10,330 kWh (kilowatt hour). Based on this calculation, Hongcheon-gun’s annual electricity consumption is approximately 698,638 MWh .

■ When and why do open refrigerators start to be used?

Why do convenience stores have doorless refrigerators?

I asked the convenience store industry. The answer that came back was “It has been like that since ancient times”.

In addition, there are side effects.

Refrigerators without doors improve product accessibility because products can be seen right in front of your eyes. In addition, it is also consumer-friendly because consumers do not have to open the door .

However, if you go through the trouble of opening and closing the door once, you can save electricity for 70,000 people for a year.
