The cold winter is unbearable for many people who are afraid of the cold. Even if they wear thick clothes, they still feel cold if there is no heating equipment in the room. At this time, heaters, heaters, air conditioners, etc. come in handy, but it should be known that while these appliances can bring us warmth, their power consumption is also huge. Generally speaking, the power of heating equipment is around 1000-2000 watts. Let’s take a look at which electric heater, heater and air conditioner consumes more electricity.
Comparison of heating appliances
1. Applicable power:
Take the needs of a 20-square-meter room as an example.
(1) Heater: Applicable to a heater with a power of 1800 watts.
(2) Heater: electric heater with a power of 2000 watts.
(3) Air conditioner: suitable for 2 hp air conditioners, heating power 1800 watts + auxiliary electric heating power 1500 watts = 3300 watts.
2. Energy efficiency ratio:
(1) The energy efficiency ratio of the heater: 1:1, consumes 1000 watts of electricity and generates 1000 watts of heat.
(2) The energy efficiency ratio of the heater: 1:1, consumes 1000 watts of electricity and generates 1000 watts of heat.
(3) The energy efficiency ratio of the air conditioner: 1:3, consumes 1000 watts of electricity and generates 3000 watts of heat.
3. Comparison of heaters and air conditioners
(1) The high thermal power of heaters is 1800W; it produces 1800 watts of heat.
(2) 1.5P air conditioner heating power 1200 watts + auxiliary electric heating 800 watts = 2000 watts, generating 1200*3+800*1=4400 watts of heat.
4. Comparison of heaters and heaters:
(1) It is recommended to use heaters with PTC ceramic heating elements, which only generate heat and do not emit light .
(2) Do not use heaters, which generate heat and light. Part of the power is wasted on lighting.
5. Comparison of air conditioners, fan heaters and heaters:
(1) The energy efficiency of air conditioners is high, and the power consumption of 2 air conditioners is 3300 watts , can generate 1800*3+1500=6900 watts of heat, and can raise the temperature of the entire room to 20 degrees, with good comfort.
(2) Fan heaters and heaters have low energy efficiency and are only suitable for local heating, which has little effect on raising the temperature of the entire room and is less comfortable. Even if the fan heater and heater with a power consumption of 3300 watts are used, it can only generate 3300 watts of heat, which is less than half of the same power air conditioner.
It can be seen from this that it is recommended to use air conditioners when comparing heaters, heaters and air conditioners.
Fixed speed and variable frequency air conditioners
Household air conditioners are divided into variable frequency and fixed speed ones. The ability of the same number of air conditioners to adjust the indoor temperature, the inverter air conditioner is greater than the fixed speed air conditioner. Inverter air conditioners are relatively cost-effective and more energy-efficient to use. In addition, the inverter air conditioner can accurately control the temperature and prevent “air conditioning disease” in certain procedures.
1. Electricity cost of fixed-speed air conditioner:
①The startup current of the fixed-speed air conditioner is several times the rated current, and the fixed-speed air conditioner is running Frequent start and stop, very power-hungry.
②The fixed-speed air conditioner keeps heating at the rated high power during operation. After the room temperature rises to the set temperature of the air conditioner plus 1 degree, the air conditioner stops. After the air conditioner is stopped, when the room temperature drops to the set temperature of the air conditioner minus 1 degree, the air conditioner starts again, and so on. The same goes for refrigeration.
③The fixed-speed air conditioner has insufficient heating capacity in winter. It has electric auxiliary heating elements, and the energy efficiency ratio is only 1. Electric auxiliary heating power is 1~2kW, which is very expensive.
2. Power saving of inverter air conditioner:
①The inverter air conditioner is started by soft start, no inrush current, and no waste of electricity.
②Inverter air conditioner runs at high frequency to heat up during operation. When the room temperature reaches the set temperature of the air conditioner, the air conditioner changes to low frequency operation to keep warm without stopping. The power consumption of continuous low frequency operation is only one-third or even one-fourth of the rated power. The same goes for refrigeration.
③Inverter air conditioners do not have electric auxiliary heating elements that consume a lot of electricity.
In summary, the inverter air conditioner saves energy and electricity than the fixed speed air conditioner.
How to buy heaters to buy
Safety performance Consumers should pay attention to whether they have multiple safety protections such as temperature limiters and thermostats when purchasing. The material used, the strength of the product’s drop resistance, and the welding process.
The energy-saving and environmental-friendly heater will not cause pollution, and it also increases health protection on the basis of safety. For consumers, when choosing a heater, only those heaters with higher thermal efficiency and higher electrical energy conversion rate can make the home warmer on the premise of saving energy.
Brand credibility Many consumers tend to pay more attention to the price and performance of the heater and ignore the brand of the heater when purchasing heaters. Industry experts suggest that consumers should choose models with higher brand awareness and higher sales when purchasing heaters.
After-sales service In addition to the above points, after-sales service is also an important issue that consumers should pay attention to. Generally speaking, well-known brands have relatively good after-sales service.
Whether the product is fully functional is a matter that needs attention. Many heater brands are doing well. Take the wall-mounted heater as an example. This heater can be used on the desktop, on the wall, or in the bathroom. In addition, this heater also has an electronic remote control function, so even the elderly with limited mobility can operate freely from a distance.
Air Conditioner Purchase
When choosing an air conditioner, it is recommended to choose those companies with strong strength, high brand awareness and perfect after-sales service The product. This is based on two considerations:
The first is to ensure the implementation of after-sales service, because air conditioning is a large household appliance, and after-sales service is very important. According to relevant national regulations, the compressor should be guaranteed for 3 years. The second is from the perspective of quality, because the air conditioners with strong corporate strength and high brand awareness are relatively stable in quality.
Choose good merchants In the selection of merchants, industry insiders suggest that you should first choose those big merchants with strength and influence in the local area, because these merchants have many varieties and sales, and generally have professional The installation and commissioning team has guaranteed installation and commissioning quality and perfect after-sales service. The second is to choose those long-term distributors of air conditioners, try not to buy from short-term distributors, because such distributors will greatly discount the after-sales service.
The purchase of an air conditioner is a kind of household appliance that consumes a lot of money. If the power selected is too small, it will not work; if the power is too large, it will be a waste. Therefore, when consumers choose the power of air conditioners, they need to buy them in quantity.
Purchase of heaters
Various styles and safety first, choose according to your environment and space size
Style selection There are desktop heaters , Vertical and wall-mounted, the desktop heater is small and exquisite, the vertical heater has smooth lines, and the wall-mounted heater saves space. Fan heaters are generally beautiful and elegant in appearance, and are equipped with popular color shells such as red, dark gray and blue, making the heater quite fashionable.
Safety performance When purchasing heaters, safety should also be given top priority, such as whether the machine has overheating and overcurrent protection devices, and whether it has the function of dumping and power-off, especially for bathroom heaters. The fan must be waterproof and splash-proof, so you should carefully check whether there is a waterproof mark on the machine.
Quality certification should point out that products with the Great Wall certification mark issued by China Electrotechnical Commission have better quality assurance. Not seeking the most satisfactory style, but the best internal quality and safety guarantee is the key to choosing a heater.
Precautions
1. The heater has a large power and should not be used with high-power electrical appliances at the same time, otherwise it will easily damage the heater. If there are electrical appliances that are prone to sudden changes in current and are more frequent, such as electric welding machines, impact drills, etc., are used with the heater at the same time, it is more likely to damage the heater. It is best to use a power strip with an overcurrent protection device or a regulated power supply.
2. The heater must use a standard three-hole socket with ground wire. Never use a two-hole socket without a ground wire by yourself, because it is easy to generate static electricity, and sometimes it will feel like an electric hand, which is more dangerous. The socket cannot be located directly above the heater. When no one is in the room, be sure to unplug the heater.
3. Items cannot be covered on the heater. The surface temperature of the heater is high. Once the items are covered, the heat cannot be dissipated in time, which will cause burn-in and ignition of other items. Some people like to stay close to the heater to keep warm, and even put their hands and feet on the heat sink, which is very easy to get burned.
4. In dry winter, the skin has poor moisturizing ability. If the heater is used indoors, the environment will be drier, causing the skin to be dehydrated, chapped and itchy. Therefore, when using a heater at home, you should find ways to increase the indoor humidity, such as raising some hydroponics in the house, putting a few pots of water, mopping the floor frequently, using a humidifier, etc.
