Energy-saving air conditioning articles
â— Misunderstanding 1: Inverter air conditioner definitely saves energy
Many consumers believe that inverter air conditioners must be energy-saving. In fact, this concept is wrong. From the perspective of national air-conditioning energy efficiency standards, it should be said that level 2 energy efficiency is considered to be energy-efficient air conditioners. Whether it is inverter air conditioners or fixed-frequency air conditioners, it is necessary to achieve this threshold to be energy-saving air conditioners. Inverter air conditioners that do not meet the level 2 energy efficiency standards are also Low energy efficiency air conditioner. In addition, whether the frequency conversion product is really energy-saving is also closely related to the usage habits. Because the inverter air conditioner has strict requirements on the use environment, the heat load is required to be small in operation, the setting degree and the environmental degree difference are not too large, and the general use time is 6 More than an hour, only under these conditions, the inverter air conditioner operating power is lower than the average power, in the most power-saving state.
â— Misunderstanding 2: The smaller the volume, the more energy saving
At present, many manufacturers are making efforts to promote small-sized indoor models, but consumers cannot focus on the volume of air-conditioned indoor units. Some high-quality air conditioners are compact and reasonable, such as multi-fold heat exchangers, dual-drainage systems, etc., to compress indoor units, but more small-sized indoor units are based on loss of performance and quality and material savings. For small size purposes. Therefore, the large size of the indoor unit does not mean that the technology is backward. The small size indoor unit does not mean that the technology is advanced, and it does not mean energy saving. Do not use the external dimensions as the standard when selecting the air conditioner.
Energy saving tips
Nowadays, inverter air conditioners have become the mainstream in the market, and many people often use inverter air conditioners as ordinary air conditioners because of their insufficient understanding of the working principle of inverter air conditioners. As a result, inverter air conditioners known for energy saving are ultimately not energy-saving and even more energy-intensive. How to buy the inverter air conditioner correctly?
1. Avoid switching air conditioners back and forth when using inverter air conditioners. After the inverter air conditioner is turned on, it will intelligently adjust the operation of the compressor. When the room temperature reaches the set temperature, the air conditioner will operate at a low frequency and energy saving. When the room temperature changes, the air conditioner will perform the cooling heat according to the temperature control induction. If the air conditioner is switched on and off too frequently, there is not much difference between using the inverter product and the fixed frequency product.
2. When purchasing air conditioners, be sure to purchase according to the actual area to avoid overloading the air conditioner. Otherwise, not only the temperature control effect is not good, but also the electricity is more expensive.
3. Inverter air conditioner has many functions and outstanding performance, but it does not mean omnipotence. Frequency conversion products are also relatively advantageous in terms of functions or intelligent functions, but they also need to pay attention to some problems when they are used in daily use.
4. The outdoor unit of the inverter air conditioner has a microcomputer control board to control the operation of the air conditioner inverter compressor, and the circuit board is easily damaged in a high temperature and humid environment, so the outdoor unit should be installed in a dry and ventilated place, avoiding sun exposure and rain as much as possible. Dripping.
5. The temperature setting should not be lower than 26 °C. Because it is below 26 °C, the energy consumption has entered the low-efficiency area of ​​the air conditioner, and the air-conditioning operation is more expensive.
6. When the air conditioner is not in use, the power should be turned off to avoid standby power consumption.
Energy-saving washing machine
â— Misunderstanding 1: The longer the soaking time, the easier it is to clean.
This argument is very unscientific. Because the laundry is soaked for too long, most fabrics will hydrolyze, reducing the life of the garment. In general, soaking for 10-15 minutes is most appropriate.
â— Misunderstanding 2: All kinds of clothes can be washed together
Some people are used to throwing the changed clothes, whether they are outerwear, underwear or socks, into the washing machine or in the basin. This will not only make the clothes more dirty, but also set up related procedures for washing the dirtiest clothes, resulting in prolonged washing time and wasting energy.
â— Misunderstanding 3: The more the laundry detergent is placed, the better.
Many people think that the more laundry or washing powder is put, the cleaner the clothes are washed. In fact, this is a wrong concept. When the amount of detergent in the water reaches saturation, the excess detergent does not increase the cleansing power. To use the detergent efficiently and economically, the proper amount of detergent must be taken according to the amount of water used in the laundry.
â— Misunderstanding 4: The longer the washing time, the better.
The longer the laundry is washed, the better the cleaning effect is not necessarily. For stubborn stains, pre-dip, pre-wash stained areas with detergent and remove them properly. Washing time should not be too long, otherwise it will damage the fiber of the clothes, and it will consume power and water resources unnecessarily.
Energy saving tips
1. Soak and wash first. Soak the clothes in a fluid soap or detergent solution for 10-14 minutes before washing, let the detergent and dirt on the clothes work, and then wash. This will reduce the running time of the washing machine by about half, and the power consumption will be reduced by half.
2. Separation and color washing, first shallow and deep. Different colors of clothes are washed separately, not only are washed clean, but also washed quickly, which can be shortened by 1/3 time compared with mixing.
3. Thin and thick first. Generally, the chemical fiber and silk fabrics with thin texture can be washed in four or five minutes, while the thick cotton and wool fabrics can be washed in ten minutes. Washing thick and thin separately can effectively shorten the running time of the washing machine than mixing and washing.
4. Moderate water consumption. Too much water will increase the water pressure of the wave plate, increase the burden on the motor, increase the power consumption; too little water will affect the ups and downs of the clothes during washing, increase the washing time, and increase the power consumption.
5. Correctly grasp the washing time and avoid invalid movements. The degree of washing of the clothes is mainly related to the degree of soiling of the clothes, the variety and concentration of the detergent, and is not proportional to the washing time. Exceeding the specified washing time, the washing degree will not be greatly improved, and the electric energy is consumed in vain.
6. The procedure is reasonable. After washing the clothes, it is best to dry the clothes and squeeze out the dirty water, so that the time can be shortened when rinsing, and water and electricity can be saved.
7. The washing machine should be placed in a flat and dry place, so that it can better use its washing efficiency and reduce electricity consumption.
8. Pay attention to the use of the belt. After the washing machine is used for a period of time, the pulley that drives the washing machine tends to slip, and the belt needs to be tightened to achieve the purpose of saving electricity.
Energy-saving refrigerator articles
â— Misunderstanding 1: Use power consumption as the only ruler for energy saving or not
The effective volume, refrigeration capacity and climate type of the refrigerator affect the power consumption of the refrigerator. For example, a refrigerator with a daily power consumption of 0.29 degrees has many models on the market, but by comparison, we find that if the volume of the freezer compartment is larger, the refrigeration capacity is stronger, that is, the energy saving of the refrigerator is stronger. Therefore, when we buy a refrigerator, we can't just care about the daily power consumption, but forget other related factors.
â— Misunderstanding 2: Ignore compressor power
The compressor is called the "heart" of the refrigerator, but many consumers ignore the power of the "heart" when purchasing. In order to reduce the power consumption per unit time, some energy-saving refrigerators often adopt the “small horse-drawn cart†approach to reduce the power of the compressor. Although the power consumption seems to decrease in the same time on the surface, the output power of the compressor is small, which not only causes the cooling speed to be slow, affects the quality of food storage, but also causes more power consumption due to the extended cooling time.
â— Misunderstanding 3: Ignore the thickness and density of the back and bottom insulation layers
If the insulation layer of the back and bottom plates of the refrigerator is too thin, even if the compressor of the refrigerator is full of power, it will lead to the loss of cold air and the increase of external heat transfer, which eventually leads to a linear increase in power consumption.
â— Misunderstanding 4: Ignore the comprehensive configuration of the refrigerator
The refrigerator can only guarantee real energy saving if the overall system is organically coordinated. Taking refrigerated lighting as an example, if the refrigerator uses an ordinary light bulb, the light bulb may consume more power than the LED white light, and the service life and safety are also relatively low.
Energy saving tips
1. For every 5 °C increase in temperature around the refrigerator, it will increase the internal power consumption by 25%. Therefore, the refrigerator should be placed as far as possible away from the heat source, and it should be ventilated and shaded.
2. The opening time of the refrigerator should be short. If there is a power outage, do not rush to open the refrigerator door.
3. Wait for the hot food to cool before putting it into the refrigerator. Otherwise, the temperature inside the refrigerator will rise rapidly, and the frost thickness on the surface of the evaporator will increase, resulting in prolonged compressor working time and increased power consumption.
4. Wash and drain the foods with more water, such as fruits and vegetables, and wrap them in a plastic bag to prevent the water from evaporating and thickening the frost layer to increase the power consumption.
5. The refrigerator should store enough food to avoid affecting the internal air convection, affecting the fresh-keeping effect and increasing the working time of the compressor.
6. Ice and cold drinks should be arranged in the evening in the evening. The lower temperature in the evening is conducive to the condenser cooling, and the refrigerator is less open to access food at night, and the compressor has a shorter working time, which is conducive to saving electricity.
Energy-saving TV
â— Misunderstanding 1: TV power consumption is not big
In fact, the power consumption of flat-panel TVs is not low, much higher than traditional CRT TVs. Generally, the energy consumption of flat-panel TVs is about 200 watts. If you look at 4 hours a day, you will consume 0,8 degrees of electricity, which is equivalent to the power consumption of a refrigerator. So don't turn off your TV when you watch TV. Don't use TV as background music.
â—Miscellaneous 2: Only use the remote control switch
You should not use the remote control only when shutting down, but turn off the power on the TV. Because the remote shutdown does not turn off the power, the TV is actually in standby, and it is also consuming power.
Energy saving tips
1. The size of the TV volume determines the amount of power consumption, so when using it, the volume of the TV should be adjusted to a suitable level, which not only saves power, but also does not interfere with neighbors. According to tests, for every 1 watt of audio power added to the TV, the whole machine will increase the power consumption by 3-4 watts, and it will cause hearing fatigue and hearing loss for a long time in a loud environment.
2. The brightness of the TV is also related to energy consumption. The brightest and darkest power consumption of TV is between 30 and 50 watts, especially among plasma TVs. The brightness of the TV should be adjusted to a more comfortable level. It can open a low-wattage fluorescent lamp indoors and turn the brightness of the TV to a small point. This not only saves electricity, but also has good viewing effect, and it is not easy to make eye fatigue.
3. Add a dust cover to prevent dust from entering the TV. Because there is more dust, it may leak electricity and increase power consumption.
