Hot water bottles, heaters, air conditioners, floor heating, various weapons for heating in the south
Heater VS air conditioner: which cost is higher
How do southerners get through the wet and cold winter? From the hot water bags of the old soup, to the air conditioners and heaters, to the floor heating in recent years, the way of heating in the south can be described as varied. From the current point of view, air conditioners + heaters are the way for most southern families to spend the winter.
Some people think that the heater itself is much cheaper than the air conditioner, and the size is petite. Considering the heating effect, it seems that the price is much higher. Is it really?
We compare the 2000 watt heater with a 1 air conditioner to see which one is more expensive?
Air conditioner: The compressor power of one air conditioner is 745W, and the power of the wind turbine inside and outside is about 100W.
745+100=845W=1 total power of air conditioners. (Note: 1 air conditioner has a heating capacity of 2500W. The heat is not the power consumption of the air conditioner. Although the unit is the same, the difference is very large.) 845W<2000W, so the heater is more expensive.
In addition, the heater is purely to increase the temperature of the air inside the house, which is not conducive to air circulation. The air conditioner is to increase the temperature of the outside air and then change it into the house, which is conducive to air circulation.
But there is a question, why is winter air conditioning heating generally not as good as summer cooling. The reporter interviewed a number of air-conditioning manufacturers technical personnel, the reasons are many.
In the north, a single refrigerating air conditioner is used, and in the south, a refrigerating and heating air conditioner is used. However, air conditioning is mainly for cooling services. Under such design principles, the heating effect is relatively poor.
In addition, the outdoor temperature in winter is low, especially below zero degrees Celsius, and the outdoor unit is prone to frost. When people turn on the air conditioner, it must solve its own defrosting problem before it can warm the room. It takes a certain amount of time. At this point, the air conditioning heating will be intermittent. The user will think that the machine is not working, but the outdoor unit is "thawing".
Secondly, the density of hot air is small and it is easy to run up, so it takes a long time for everyone to feel the temperature increase. Unlike the summer, when the cold air sinks, people can quickly feel the temperature changes.
When many households purchase air conditioners, they will largely refer to the "power" rankings of air-conditioning and refrigeration heating in their respective minds. Yesterday, the reporter interviewed the technicians of air-conditioning brands A and B with better heating performance in the folk reputation. For the heating "power", they mentioned the "electronic expansion valve", which is one of the four major components of the air conditioner, which can precisely control the flow of the refrigerant (Freon), thereby indirectly controlling the temperature accuracy of the entire air conditioning system; The air supply distance is about 3-4 meters, and some air conditioners of these brands can reach a distance of 13 meters.
With the improvement of living conditions, Hangzhou also has some well-decorated communities to achieve "central heating" through the unified installation of central air-conditioning, such as the Golden Coast, Sunshine Coast, and Greentown's real estate. In addition, many households are currently laying floor heating when trying to decorate. The heating pipes need to be laid under the floor. The disadvantage is that it must be a newly renovated house, and if the fault is repaired, it is troublesome. Of course, the cost of heating and the cost of using it is relatively high. . The installation cost is about twice that of the heating.
Nowadays, people are getting more and more delicate. The Sanda men of the year are now preferred to buy central air conditioners.
In the age when there was no air conditioning, in those snowy winters, those who moved from the warmth of the north to the south to learn and find their stories could resonate in this generation.
Songjiang’s hometown is in Jilin, so he is called “Songjiangâ€. In 1985, he was admitted to Fudan University.
The winter in the south left a deep impression on this Northeastern guy. When I was a child, I was in the countryside and I had a hot girl. When I was young, my family entered the city and there was a magic radiator in the house.
The cold in the south is full of water. For example, the first snow every year is often accompanied by rain, and it is "formal" when it is down. There is a Hangzhou person in Songjiang's classmates, which describes the coldness of the South. The Hangzhou dialect is called "瀴" (ying is the fourth sound), which means that it is cold and cold, and it is very fascinating.
At that time, there was no warm winter saying that at least three or four heavy snows would be required every winter.
Songjiang said that the bedroom is actually fine. At that time, the dormitory was so small that it was enough to reach out from each other on the two sides of the bed. A bed of eight bloody young men, the water mist on the glass window in the morning becomes "water flow", and the white wall under the window sill is watery in winter.
In retrospect, there are winter evenings, chairs in study rooms, wood-based panels, and chilly and hard. A skilled girl will sew a cotton pad to the buttocks.
In those days, the gifts that girls sent to their boyfriends were more popular with hand-knitted gloves or homemade cotton pads. There are small ponds on Fudan campus and there are winding water systems. On autumn nights, there are often boys where lobsters are caught. Songjiang said that there is no danger in fishing lobsters there. Because there are trees next to the dimly lit trees, there are often couples who are intimate. Therefore, every winter, Songjiang worried about them, where these hot people went.
"Songjiang, do you wear long trousers?" "Wear, but only wear one." In order to fight the winter and send a college career without a girlfriend, Songjiang practiced Sanda. He also scored the top three in Shanghai.
After graduating from college, Songjiang stayed in the south. He saw a lot of northern langs. When the winter was approaching in the south, they put on their long trousers and wore scarves. Even so, they still wore vibrato.
In 2005, Songjiang had conditions. He bought a three-bedroom, 150-square-meter apartment in a finely decorated building. His most fancy is that each set has central air-conditioning.
As he grows older, Songjiang, who is in the south, is increasingly looking forward to the home in the north. Therefore, he has made the home in the south warm, and the room temperature is around 20 degrees Celsius every day, wearing a shirt or a pullover sweater.
He said that his family's electricity bill has been arrogant since November every year, from 700 to 1,000 yuan per month to 1,500 yuan a month. The heating cost of the home heating in Changchun is 28 square meters per square meter, and it takes about one winter, starting from November of each year to the end of March.
