HC air conditioning and refrigeration network air conditioning is one of the essential home appliances in the family. When almost every household is in the buyer's electricity, the first thing to consider is air conditioners, refrigerators, washing machines. These things are almost all in the family now. The most common home appliances. But what should we choose when purchasing air conditioners? Is it good to buy a variable frequency or a fixed frequency? Everyone may have this doubt. We don’t have a simple understanding of what air conditioners should buy today. Need to help everyone.
Working principle of fixed frequency air conditioner and inverter air conditioner
The biggest difference between fixed-frequency air conditioners and inverter air conditioners is that they work differently. The fixed-frequency air conditioner is started and turned off according to the temperature set by the air conditioner. Since its output power is constant, the fixed-frequency air conditioner stops working when the indoor temperature reaches the set temperature. When the temperature rises, the fixed-frequency air conditioner starts running again. The inverter air conditioner can be automatically adjusted according to the indoor temperature. When the indoor temperature exceeds the set temperature, the inverter air conditioner outputs power at a low frequency and intelligently controls to maintain the indoor temperature.
Is the inverter air conditioner really saving electricity?
Some people don't understand, they feel that the intermittent work performance of fixed-frequency air conditioners can easily lead to illnesses in the family. And the noise is very high during work, and the night will affect the quality of family sleep. Therefore, they all prefer to buy so-called energy-saving and comfortable inverter air conditioners.
But does the inverter air conditioner really save power? In fact, they are all bluffing people. In our home, we use inverter air conditioner. Only when it is turned on for 6 hours for a long time, and continuously keep going, the inverter air conditioner will save about 30% than the fixed frequency air conditioner. However, our average family does not meet this standard, and few people will turn on the air conditioner at home for a long time. Therefore, inverter air conditioners are not as economical as the propaganda said.
Another sad point is that the price of inverter air conditioners is very expensive when purchased, which is about 1/3 to 1/4 more expensive than fixed-frequency air conditioners. Moreover, the internal system of the inverter air conditioner is still very complicated, so the failure rate can be high. Many people are willing to buy it, but the maintenance cost is enough to make people feel distressed. The maintenance cost is even more than the electricity cost saved for many years. It is really worth the loss.
I recommend several ways to make the air conditioner more energy efficient.
1, correct purchase, reasonable use
First, buy air conditioners to buy on demand, whether it is the appearance or the number of products equipped with the above, the user only buys correctly, will not be wasted in the future use or the number of too small and too much power consumption, And this is also a low-carbon, healthy use of air conditioning performance. Second, we must learn to use air conditioners more energy-efficient in daily life.
2, the degree of room sealing should be done well
If the air-conditioned room is not sealed enough, then the maintenance structure of the room needs to be improved. For some rooms, the structure of the door and window is poor, and the gap is large, and some emergency improvement can be done; it is better to use thick curtains, the curtain fabric is thicker and deeper, and the room temperature effect caused by sunlight radiation can be reduced. Reduce the loss of cold air, while opening the door and window can reduce the heat input outside the room, which is conducive to power saving.
3, turn off the air conditioner ten minutes in advance
Before going out, you should turn off the air conditioner in advance. It is best to turn off the air conditioner ten minutes before leaving the house. In this ten minutes, the room temperature is enough to make people feel cool, and develop the habit of turning off the air conditioner in advance to save energy.
4. When the air conditioner exits during cooling
When the air outlet is upward in the cooling, the air flow is easy to go down after the air temperature becomes low, and the cooling effect is good, and the energy saving effect can also be achieved.
5, the outside machine should be ventilated to avoid the sun
The air-conditioner outside machine should try to choose the place of ventilation and the shade of the room. It is easy to heat the outside machine in the summer sun, thus affecting the heat dissipation effect of the air conditioner. If the conditions are not allowed, the outdoor unit can only be installed on the sunny side, and the residents can install the awning on the top of the outer machine. If the conditions are not met, the air conditioner outdoor unit should be covered with a sun shield.
6, do not wear "raincoat" for the outside machine
Some people are worried that the air conditioner outside the machine will be damaged and rusted due to weather such as rain, and it will be covered with rain-proof materials on the outside of the air conditioner. In fact, the brand air conditioner outdoor unit generally has a waterproof function, and the air conditioner "wearing raincoat" will affect heat dissipation and increase power consumption.
7. Regularly clean the heat sink and filter
Excessive dust on the external heat sink can affect heat exchange and can greatly increase power consumption. It is best to use a professional for more than 3 years to clean up once. The air-conditioning filter should be cleaned frequently, which can make the air-conditioning air supply smooth, reduce energy consumption, and is beneficial to human health. Otherwise, the mesh cover will also affect the cooling effect.
8, sleep function is also saving electricity
When sleeping, you should use the air conditioning sleep function to achieve 20% power saving.
9, do not frequently switch on and off
In order to save electricity, some people often turn off the air conditioner when it is turned on. In fact, the air conditioner frequently switches the most power, and the compressor is easily lost. When the air conditioner is running, if it feels too cold, there is no need to turn it off, just turn the set temperature up. The “ventilation†switch cannot be in the normally open state, otherwise it will increase the power consumption. Less opening of doors and windows can reduce heat input outside the room, which is conducive to power saving.
to sum up
Inverter air conditioners are of course energy-saving, but this depends on the use of air conditioners in the home. In fact, the state stipulates that high-energy-consuming electrical appliances are prohibited from being produced, so the technology is also constantly improving. Is it energy-efficient to see the energy efficiency on the commercial label? I know it. If you want to save money, you can save money by using it and paying attention. I hope that I can help some friends who need to buy air conditioners.
