On August 23, Chengdu's high temperature red warning signal was issued for 13 consecutive days. As of 16:00, the average maximum temperature in Chengdu was 39.8 ℃, and the maximum temperature in the new eastern district even reached 43.6 ℃.
In such extremely high temperature weather, the contradiction between power supply and demand is extremely prominent. Some shopping malls and office buildings have responded to the call to save electricity and turned off lights and air conditioners.
But it is really hot in the indoor office, how to solve it?
Some netizens thought of the cooling method of enlarging ice cubes in the office.
How does this cooling effect work?
Which is more cost-effective than air conditioners?
Is it worth promoting?
In this regard, the reporter interviewed the person in charge of an ice-making factory in Wuhou District, Chengdu, to hear what he had to say.

Ice cubes are mainly used in factories and agricultural products
The effect of a single office is not obvious
"The sales of ice cubes have been very good recently." Ms. Jiang, the owner of the ice factory, said that the weather this summer is hotter than previous years, and the demand for ice cubes is also very large.
However, due to the recent shortage of power supply, in order to ensure the electricity supply for residents, the factory has been shut down since 7:00 in the morning, and ice-making can only be started after 8:00 p.m.
"There are a lot of orders, but the current production capacity is limited, and the ice cubes are in short supply."
She introduced that industrial ice is generally sold to factories, fresh water markets and other places, but this year suddenly received a lot of orders from office buildings.
"Because there is no air conditioner in the office building, some companies will buy ice cubes to cool down the room, some will buy a few pieces of ice, and some will buy hundreds of pieces of ice."
What is the effect of putting ice cubes in the room to cool down?
"Putting a single ice cube indoors and blowing it with an electric fan can have a certain cooling effect, but the effect is not very obvious, and the cooling range is also very limited, which does not play a big role in such high temperature weather." Ms. Jiang said .

A piece of ice costs about 5 yuan
To cool the room requires a lot of placement
According to reports, a piece of industrial ice weighs about 80 pounds. How long does it take to melt completely?
"It usually takes about 20 hours to melt indoors, and only seven or eight hours outdoors." Ms. Jiang said that the thickness and hardness of industrial ice cubes are different from edible-grade ice cubes, so the melting speed is different.
She said that the cost of freezing a piece of ice is four or five yuan, and the price is more than ten yuan. If the market demand is large, the price may rise slightly.
If you want to make a room of about 10 square meters feel the cooling brought by ice cubes, it may take 10-20 ice cubes to achieve the cooling effect.
So if the air conditioner in the house is set at about 27 degrees Celsius, how much electricity will it cost to run it for a day?
The reporter checked the price list of the Chengdu Power Supply Company of the State Grid Sichuan Electric Power Company. According to the combined meter residential electricity price of 0.53 yuan per kilowatt-hour, the electricity cost for each air conditioner is about 12 yuan per day depending on the energy consumption.
Therefore, the electricity bill of turning on the air conditioner for a day is actually cheaper than buying a piece of ice, and the cooling effect of the air conditioner is definitely better than that of ice cubes. How do you choose?
