On August 23, Chengdu's high -temperature red warning signal was released for 13 consecutive days. As of 16:00, the average maximum temperature in Chengdu was 39.8 ° C, and the highest temperature in the eastern new district even reached 43.6 ° C. In such extremely high temperature weather, the contradiction between power supply and demand is extremely prominent. Some shopping malls and office buildings responded to the call for electricity to use electricity to turn off the lights and air conditioners, but how to solve the indoor office staff is really hot. Some netizens thought of the office enlarged the ice. The cooling method of the block.

What is the effect of such cooling? Which is cost -effective compared with the air conditioner? Is it worth promoting? In response, the reporter interviewed the person in charge of a ice -making factory in Wuhou District, Chengdu, and revealed the secrets for everyone.

Ice factory owner:

Big ice cubes are mainly factory and agricultural use of a single office office. The effect is not obvious

"Recently, the sales of ice cubes are very good." Ms. Jiang said that the weather this summer is hotter than in previous years, and the demand for ice cubes is also very large. However, due to the tight power supply in the near future, in order to ensure the electricity consumption of residents, the factory is in a state of stopping from 7 am, and can only start ice production after 8 pm. "There are many orders, but the current production capacity is limited, and the ice cubes are a bit in short supply."

She also introduced that industrial ice cubes are generally sold to factories, aquatic fresh markets and other places, but this year suddenly received a lot of orders from writing buildings. In the past, there was almost no such situation. "Because the office building does not have air conditioners, these people will buy ice cubes and place them indoors to cool down. There are some ice, and there are many people buying hundreds of ice."

What is the effect of ice cubes in the indoor cooling? "Putting the ice in the room with an electric fan can play a certain amount of cooling, but the effect is not obvious, and the scope of cooling is also very limited. It can't play much in such high temperature weather." Ms. Jiang said.

Calculate the account

Make a piece of ice cost of about 5 yuan to make the room cool down and need to be placed in large quantities

According to reports, the volume of an industrial ice cubes is 40cmx20cmx70cm, about 80 catties. How long does it take to completely melt? "Generally, it takes about 20 hours to melt indoors, and only 7 or 8 hours outdoors." Ms. Jiang said that the thickness and hardness of the industrial ice cubes are different from the edible ice cubes, so the melting speed is different.

She said that the cost of freezing a piece of ice was 4 or 5 yuan, and the price was about ten dollars. If the market demand was large, the price may rise slightly. If you want to make a room about 10 square meters feel the cooling brought by the ice cubes, "it may require about 10-20 yuan to achieve the cool effect."

So if you set up a one -meter air conditioner at the home, how much electricity does it take to open a day? The reporter checked the price list of Chengdu Power Supply Company of the State Grid Sichuan Provincial Electric Power Company, and calculated at about 0.53 yuan per kilowatt -hour electricity price of the residents of the table. One air conditioner was based on the energy consumption, and the electricity fee was around 12 yuan.

The electricity fee for turning on the air conditioner one day is actually cheaper than a piece of ice, and the cooling effect of the air conditioner is definitely better than ice cubes. How do you choose?
