Which of the air conditioners consumes more electricity compared to cooling and heating?

I think that the heating of the air conditioner will consume more electricity, because the air conditioner is originally designed according to the standard of refrigeration, so the heating performance of some air conditioners will be very poor, and if you want to make the air conditioner heat, you need to consume more electricity, so if we want to heat, we can buy special heating equipment.

Heating will consume more electricity, because the air conditioner was originally to meet the cooling needs, and the heating will be slightly worse, so the power consumption is relatively high.

Air conditioning and refrigeration consume more electricity than heating, but it is not much worse, the power is relatively large when cooling, and as long as it can blow warm air when it is hot.

Air conditioning and heating are more power-intensive.

The main reason is that the air conditioner has a greater workload when heating: the air conditioner is the porter of heat, and in summer it transports the indoor heat to the outside, and the temperature in the room is high, and the heat is more, so it is more labor-saving to carry. In winter, the outdoor heat is transported indoors, and the outdoor temperature is low and the heat is less, so it is naturally more difficult to carry.

Because of this, air conditioners not only need more power to heat up, but also take longer. If the air conditioner is turned on for 1 hour, the compressor may only work for 20 minutes during refrigeration; The compressor may need to work for up to 40 minutes while heating. Power consumption = power * time, the heating power and working time of the air conditioner are higher and longer than that of refrigeration, and the power consumption is naturally higher.

Air conditioning options. Normally, the cooling capacity per square meter of the ordinary bedroom of the family is 115 145W, and the cooling capacity per square meter of the living room and dining room is 145 175W. The room is well insulated, well sealed, and not facing the sun can take a small value, otherwise take a large value, and the floor height should be appropriately increased when the floor height is higher. In general, the median value can be taken, such as 130 for the bedroom and 160 for the living room.

15 square meters: 130 * 15 = 1950 (W), because there is no corresponding refrigeration capacity of air conditioning, choose the nearest 22 type;

20 square meters: 130 * 20 = 2600 (w), choose 26 type;

25 square meters: 130 * 25 = 3250 (W), choose 32 type;

28 square meters: 130 * 28 = 3640 (W), choose 35 type.

In many cases, air conditioning and heating consume more electricity than refrigeration, because the air conditioner not only has to send air in when heating, but also has to work on its own heating plate or heating, thus consuming more electricity.

How much electricity is consumed per hour in 150 square meters.

Summary. Heating, air conditioning heating and refrigeration are compared with heating and cooling, heating consumption is greater, and air conditioning heating consumes much more electricity than refrigeration.

Heating, air conditioning heating and refrigeration are compared with heating and cooling, heating consumption is greater, and air conditioning heating consumes much more electricity than refrigeration.

Heating costs electricity, because the power consumption of air acacia modulation heating and auxiliary power consumption is about twice as much as that of refrigeration. For example, the input power of refrigeration is usually about 1000 watts, and the average hour, the power consumption is generally about 1000 watts. The input power of the heating bridge family is also about 1000 watts, while the power of the auxiliary power is about 1000 watts, and some of the auxiliary power is larger, and the average hourly power consumption during heating work is about 1-2 degrees.

Whether air conditioning and cooling cost electricity or heating electricity is a question that many people want to know.

The answer is that heating consumes more electricity

Because the "auxiliary electric heating" is turned on when heating, the auxiliary electric heating is to heat the heating wire by directly using electricity, which requires a lot of power, so it consumes more electricity.

1. First of all, we see that the power consumption of air conditioning mainly lies in the compressor according to the work efficiency, and the compressor is the same in terms of power whether it is refrigeration or heating, but their efficiency is not the same, the efficiency of air conditioning is higher than that of heating, and the comfort of refrigeration is better than heating, from this point of view, heating is more power-consuming than refrigeration.

2. According to the temperature difference, the larger the temperature difference that needs to be made up for the general air conditioner in cooling and heating, the more electricity will be consumed. In the summer cooling, the indoor temperature is generally 35, we generally only need to adjust the air conditioner to about 25 degrees Celsius to feel the cool room temperature, this temperature difference is about 10 degrees. In winter, when using air conditioners for heating, the indoor temperature is 5 -7, and generally if you want to feel warm, we need to adjust the air conditioner to about 22 -25, and the temperature difference will be about 15.

Therefore, in contrast, the temperature difference that the air conditioner has to make up in summer is a little smaller, so it is also more energy-efficient.

In addition, the heating process is much more complex than that of refrigeration, and the heating wire is also needed to assist the compressor to release heat, so heating is more power-intensive.

Air conditioning and refrigeration consume a lot of electricity. I remember paying attention to the fact that the electricity consumption in a day is more than 20 degrees in summer, and the electricity consumption in a day is only about 10 degrees when the air conditioner is turned on in winter, which is less than half of that in summer.

Heating bar, the air conditioner is converted by a fan according to the outdoor temperature, which is easy to cool down, but difficult to heat up.

Air conditioning consumes more electricity to heat than cooling.

Specific analysis: The highest power consumption of air conditioning is actually the compressor, in fact, the power of cooling and heating is the same. However, in terms of efficiency, air conditioners are more efficient at generating cold air than hot air, so from this point of view, air conditioners consume more electricity to heat than to cool.

Extended information: 1. The content of refrigeration:

1. During refrigeration, the gaseous refrigerant in the air conditioner will be compressed through the compressor to become a high-temperature and high-pressure gas, and this part of the gas will be sent to the condenser after an appropriate amount of expansion through the expansion valve will dissipate a part of the heat, that is, the hot air blown out of the air conditioner.

2. In this process, the high temperature and high pressure refrigerant will drop sharply because the space becomes larger, and the temperature and pressure will drop sharply, absorbing a large amount of heat, and the temperature of the evaporator will decrease at this time, which is why the air blown out of the air conditioner is cold air.

3. In fact, from a macroscopic point of view, that is, the liquefaction heat release and vaporization heat absorption that we have learned in physics textbooks.

Second, the content of heating:

During heating, the refrigerant in the air conditioner will still be compressed by the compressor to become a high-temperature and high-pressure gas, and will be fed into the heat exchanger of the air conditioner indoor unit. In this process, the gas liquefies and releases heat, heating the air in the room.

The principle of air conditioning refrigeration refers to the principle of air conditioning refrigeration operation. After the air conditioner is energized, the low-pressure steam of the refrigerant in the refrigeration system is sucked in by the compressor and compressed into high-pressure steam and discharged to the condenser, and the indoor air is continuously circulated to achieve the purpose of reducing the temperature. The outdoor air drawn in by the axial fan flows through the condenser, taking away the heat released by the refrigerant, causing the high-pressure refrigerant vapor to condense into a high-pressure liquid.

The high-pressure liquid is sprayed into the evaporator after passing through the filter and throttling mechanism, and evaporates at the corresponding low pressure to absorb the surrounding heat. At the same time, the cross-flow fan continuously enters the ribs of the evaporator for heat exchange, and sends the cooled air to the room after heat release.

When the air conditioner is heating, the gas freon is pressurized by the compressor to become a high-temperature and high-pressure gas, which enters the heat exchanger of the indoor unit (condenser at this time), condenses and liquefies heat to become a liquid, and at the same time heats the indoor air, so as to achieve the purpose of increasing the indoor temperature. The liquid freon is depressurized by the throttling device, enters the heat exchanger of the outdoor unit (in this case, the evaporator), evaporates and vaporizes to absorb heat and become a gas, and at the same time absorbs the heat of the outdoor air (the outdoor air becomes colder). Freon, which becomes a gas, enters the compressor again to start the next cycle.

Many types of air conditioning heating need a period of preheating, preheating this time is also power consumption, although each preheating is only a few minutes at most, although the air conditioning can not consume much electricity at a time of preheating, but we must know that the accumulation of small amounts of this truth, the whole winter down we turn on the air conditioning a lot of times, so a winter air conditioning preheating power consumption accumulates, compared with the summer power consumption will have a significant gap.

Our home air conditioners are divided into indoor units and outdoor units.

The most important part of the outdoor unit is the compressor. When we start the "refrigeration mode", the gaseous refrigerant in the compressor enters the outdoor exchanger and becomes a liquid, and then flows through the pipe into the indoor exchanger, and then becomes a gas again. We know that the transformation from liquid to gas is the process of endothermy, which takes away the heat in the room.

The "heating mode" is the opposite process, in which the gaseous refrigerant in the compressor enters the exchanger in the room, turns into a liquid, and releases heat.

The reason why air conditioners can continuously deliver "heating" or "cold air" is because the liquid refrigerant continues to flow through the pipes to the outdoor exchanger, turning into gas, and then entering the room, forming a cycle.

Who is more energy-efficient than heating and cooling?

Ideal. Let's speak with data first: taking a brand of air conditioner in the market as an example, a household wall-mounted air conditioner has a cooling capacity of 3500 watts, a cooling power of 1080 watts, and an energy efficiency ratio of 3500 1068; The heating capacity is 3850 watts, the heating power is 1120 watts, and the energy efficiency ratio is 3850 1120.

In this way, it is true that the heating efficiency is higher, is it really more energy-saving than cooling?

Actual situation. In fact, this is not the case, because the above situation is ideal, and in real life, there is a lot more to consider.

1.First of all, we have to understand that refrigeration is the basic starting point of air conditioning, heating is only an additional function, for most brands at present, the comfort of air conditioning heating is not as good as refrigeration, so many air conditioners will add electric auxiliary heating (there are in the parameter diagram above).

In this way, the operation of the compressor, coupled with the power consumption of electric auxiliary heating, makes the heating of air conditioning more than that of refrigeration;

2.If the air conditioner is often frosty in winter, it is difficult to start running, and the air conditioner will consume part of the electricity to melt the frost. This defrosting process also increases the energy consumption of the air conditioner during heating;

3.The relevant national standards stipulate the standard test conditions for the rated high temperature heating of air conditioners: 6 outdoors and 20 indoors. And when we use air conditioners in winter, it is very likely to be less than 6;

4.When it is very hot in summer, the indoor temperature is generally around 35, if you turn on the air conditioner and adjust the temperature to about 28, it will be very cool, and the air conditioner only needs to fill the temperature difference of 7 degrees.

In winter, the temperature tends to drop below 0, and the indoor temperature depends on the situation, and it is mostly around 5. Turn on the air conditioner for heating, assuming that the temperature value is also set to 28, then the heating temperature difference is as high as 23 degrees. 7 23, how's that?

Isn't the result obvious? Heating costs more electricity than cooling.

Theoretically, heating consumes less electricity than cooling.

However, due to the influence of outdoor air temperature and humidity, the outdoor air temperature is below zero degrees Celsius, and the heating of the air conditioner decreases sharply, and heating consumes more electricity than cooling at this time.
