Do you have to buy an air conditioner with inverter?

How to choose an air conditioner, must you buy inverter?

It is not necessary to buy an inverter air conditioner, inverter air conditioner cooling and heating speed is fast, the indoor temperature difference is small, good comfort, but only if each time the power on time is more than 6 hours, in order to give full play to its power-saving advantages, otherwise it is about the same as the ordinary fixed-speed air conditioning, or even more power consumption.

You should pick according to their own use of air conditioning, the frequency of use is high, each time the boot time is very long, to buy inverter air conditioning or energy-efficient ratio of fixed-speed air conditioning is more appropriate, if the frequency of use of the enamel, the boot time is short, to buy the economy of the air conditioning can be.

It is recommended that you buy a fixed-speed air conditioner with a high energy efficiency ratio, and consider installing an inverter air conditioner if it is a bedroom.

Within 10 square meters, you can install a small one-horsepower air conditioner, within 13 square meters, install a one-horsepower air conditioner can be, within 16 square meters of the bedroom, the installation of cooling capacity of 3200W 1.25 horsepower air conditioning is more appropriate, depending on the room's sealing and insulation conditions.

Do I need to buy an inverter air conditioner?

What is variable frequency air conditioning variable frequency air conditioning host is automatically stepless speed, it can automatically provide the required amount of cold (heat) according to the room; when the indoor temperature reaches the desired value, the host is able to accurately maintain the temperature of the constant speed operation, to achieve the "non-stop operation", so as to ensure that the ambient temperature is stable. What is fixed-frequency air conditioning

China's power grid voltage is 220 volts, 50 Hz, in this condition the air conditioner is called fixed-frequency air conditioning. Because the power supply frequency can not be changed, the traditional fixed-frequency air conditioning compressor speed is basically unchanged, relying on constant "on and off" compressor to adjust the indoor temperature, which is easy to cause the room temperature between the opening and closing cold and hot, and consume more electricity.

The difference between inverter and fixed-frequency air conditioning

The biggest difference between inverter and fixed-frequency air conditioning is that the principle of using the compressor on the product is different. Inverter products compressor can be turned on for a long time in the case of moderate temperature regulation, if the indoor does not need a lot of hot and cold, the air conditioning will be low-frequency state operation, intelligent constant temperature control, fixed-frequency products need to be in the case of man-made air conditioning hot and cold on/off adjustment.

Characteristics of inverter type air conditioner Energy saving. As inverter air conditioning through the built-in frequency converter, at any time to adjust the heart of the air conditioning machine - compressor running speed, so as to achieve a reasonable use of energy; because its compressor will not be turned on frequently, the compressor will be kept in a stable working condition, which can make the air conditioning overall to achieve the effect of energy saving of more than 30%. At the same time, this is the reduction of noise and extend the service life of the air conditioner, there is a fairly obvious role.

High precision of temperature control. It can control the cooling (heat) amount of the air conditioner by changing the speed of the compressor. Its cooling (heating) volume has a change amplitude, such as 36GW inverter cooling volume change of 360-400W, heating volume change of 300-6800W, so the indoor temperature control can be accurate to ± 1 ℃, so that the human body feels very comfortable.

Fast temperature regulation. When the difference between the room temperature and the withered temperature is large, the inverter air conditioner is turned on, that is, the maximum power work, so that the room temperature quickly rise or fall to the adjusted temperature, cooling (heating) effect is obvious.

Keep the room temperature constant. Inverter air conditioning using a frequency conversion compressor, inverter air conditioning according to the room cooling (heat) load changes automatically adjust the compressor operating frequency. After reaching the set temperature, the inverter air conditioner runs at a lower frequency, avoiding the discomfort caused by drastic changes in room temperature. When the load is small operating frequency is low, this time the compressor consumes less power, while avoiding the frequent start and stop, so more power saving.

Air conditioning is necessary to spend more money to buy inverter

Buy or not to buy inverter air conditioning there are several factors: 1, first of all, you need to understand the principle and characteristics of inverter and fixed-frequency (inverter air conditioning is through the outdoor compressor operating frequency to control the indoor temperature, all the advantages of inverter air conditioning thermostat noise is low on the human body is very comfortable which is the most important feature, the disadvantage of inverter air conditioning repair costs, depending on the frequency of air conditioning is through the set temperature to control the indoor and outdoor temperature. is to set the temperature to control the indoor and outdoor machine start and stop to achieve the effect, the advantage of cooling and heating very quickly, easy to maintain, the disadvantage is not constant temperature, indoor temperature difference repeatedly);

2, according to the length of time you open the air conditioning to decide: if the air conditioning time is not much time in a year, do not recommend that you buy inverter;

3, the so-called power saving, in many reasons to save electricity, such as The size of your room, orientation, their own air conditioning energy efficiency ratio, on and off situation, etc. (now on the market frequency machine is much more expensive than the fixed frequency machine, if you do not use much time I personally feel that you buy a fixed-frequency machine to save money can be enough for you to use a year of air-conditioning electricity), thank you hope to adopt!

Air conditioning to buy fixed frequency or frequency

General in the home appliance store with you that frequency than fixed frequency good that is certainly fooled you. The difference in function is only in the length of time used to make a difference. The bedroom, if you use a long time is recommended to use inverter, so that the indoor temperature is also adjusted. Office with fixed frequency on it, fixed frequency than inverter a lot cheaper, the use of time is short, even if the cost of electricity consumed more than counted, but also than the difference between the two. 1.5P United States of America's hanging 2700 is a very cheap! General home appliance stores this model price limit is about 2900 or so!

Buy air conditioning must be inverter

Not necessarily inverter, inverter air conditioning power-saving properties are needed for a long time to stabilize the room temperature at a certain temperature to be able to bring out, that is, if you use the air conditioning habits are hot open a few hours, and then turned off, and sleep a few hours at night on the shutdown, the use of this method of use does not have to use the significance of inverter air conditioning.

Inverter air conditioning can be on all night, it will automatically reduce the compressor speed after the room temperature is stabilized to a preset value, and run under energy-saving conditions to maintain the indoor temperature, the lowest night may only consume 1 degree of electricity.

In short, if you use air conditioning is as long as the home has been turned on and off, so that the room temperature to maintain a relatively stable state, then you must use inverter air conditioning. Fixed frequency air conditioners are not up to the task of maintaining a constant temperature and saving energy. If you use the air conditioning is very frugal, as long as it is not very hot on, then you still use fixed-frequency air conditioning, because a short period of time to use can not reflect the advantages of inverter air conditioning.

Do you need to buy inverter air conditioner to open 3 hours a day

No need Fixed frequency is fine

Buy heating and cooling air conditioning is not all inverter?

Inverter and heating and cooling are expressed in different meanings.

Inverter means that the air conditioner uses inverter technology, while cooling and heating means that the air conditioner has cooling and heating functions. An inverter air conditioner does not necessarily mean that it is a cooling or heating air conditioner, it could be a single cooling air conditioner.

Air conditioning is air conditioner (air conditioner), also known as cold air. It is the process of regulating and controlling the temperature, humidity, cleanliness, speed and other parameters of the ambient air in the building/structure by artificial means. It generally includes several major parts such as cold source/heat source equipment, cold and hot medium transmission and distribution system, end device and other auxiliary equipment. Mainly includes pumps, fans and piping systems. The end device is responsible for the use of transmission and distribution of cold and heat, specific treatment of air, so that the air parameters of the target environment to meet the requirements.

There is no need to buy inverter domestic air conditioning

Buy air conditioning, energy efficiency ratio is the most important parameter (of course, the cooling capacity is also very important, but this is based on the area of the election on the good, each family is the same), now the 1 level of energy-efficiency ratio of about 3.5 or so, that is, the cooling capacity is the consumption of 3.5 times, the bigger the number is the better, on behalf of the about power saving. Anything else is bullshit.

2100W power is enough to bring air conditioning, the key to see how big your area. If 10 or so square feet, get a 1 ~ 1.25P machine, you do not have any problems with power supply, the actual power consumption of air conditioning is also in the 600 ~ 800W or so, there is no need to buy an inverter machine, inverter machine is mainly more comfortable to use, he is constantly working, by adjusting the amount of refrigeration to ensure that the temperature is constant, the indoor temperature change is relatively small, but note that he also has a feature that is turned on when it is Powerful refrigeration (this feature does not seem to have a way to turn off ^_^), in this stage will work with a power higher than the nominal cooling capacity.

About auto-cleaning

The best cleaning is to take down the filter of the air conditioner regularly, say 1 month, clean it and put it back on (you can use some disinfectant to remove bacteria, but don't use 84 or something corrosive like that), this is better than any auto-cleaning effect.

Buy inverter air conditioning to pay attention to what

1. Inverter air conditioning purchase of the first point is still to look at the area of your room to determine the number of horsepower, inverter air conditioning, although the ability to adjust the power, but also in accordance with the actual housing situation to buy. The most important thing to choose the air conditioner is still the relationship between the air conditioner's horsepower and the room area, we choose what kind of air conditioner have to rely on it. If you want to buy air conditioning in the near future, you can also refer to the following table, which will certainly provide you with some help.

2. Inverter air conditioning type:

Wall-mounted inverter air conditioning: this type of air conditioning will not take up too much space in the home, adapting to more home environments. The versatile characteristics make it can be well combined with interior decoration. Wall-mounted air conditioners are mostly 1P and 1.5P, so they are suitable for some small living rooms or bedrooms. Inverter air conditioners, although powerful, but the number of horsepower to choose above or rather choose big, not small.

3. Energy efficiency labeling:

Not only air conditioning, other home appliances (washing machines, refrigerators, TVs) will be affixed with the corresponding energy efficiency labeling. From the energy label we can see the air conditioning energy efficiency rating, the higher the rating (1 for the highest) that the air conditioning energy efficiency ratio is higher, the more energy-saving. In addition, we can also see from this logo on the air conditioning model, which also prevents some stores air conditioning model labeling unclear situation. In order to adapt to the new requirements, so that the air conditioning more environmentally friendly, air conditioning energy-efficiency labeling has changed in the last year.

Energy efficiency labeling on the top labeled with the name of the producer, specifications and models, energy consumption classification, energy efficiency ratio and product input power and cooling capacity of six items. Air conditioning energy efficiency ratio labeling of air conditioning energy efficiency ratio into five levels, of which 1 level of the highest, 5 level of the lowest.

According to the State Administration of Quality Supervision, Inspection and Quarantine, the State Standardization Administration issued the "room air conditioner energy efficiency limit values and energy efficiency class" mandatory national standards (hereinafter referred to as the new national standard), fixed-speed air conditioning (also known as fixed-frequency air conditioning, relative to inverter air conditioning) energy efficiency access level has been upgraded on June 1, 2010, the original 3, 4, 5 level of low energy-efficiency products due to the failure to reach the access threshold, the enterprise will not be able to produce, the original 3, 4, 5 low energy-efficiency products. Threshold, the enterprise will not be able to produce, the original 2-level energy efficiency in the new national standard into 3-level, is the entry level, that is, after the implementation of the standard products to meet the threshold for market access, the original 1-level energy efficiency into the new national standard in the 2-level, that is, the energy-saving evaluation value, that is, the evaluation of air-conditioning products whether the energy-saving minimum requirements of the new standard in the 1-level is the highest energy efficiency.

4. Explanation of the name of the air conditioner:

(1) K: room air conditioner

(2) structural form: F-split room air conditioner

(3) Function code (mono-cooled type does not have this code): R-heat pump type (warming); D-electric heating; BD-heat pump auxiliary electric heating

(4) nominal refrigeration capacity: expressed by *** numbers, the value of which takes the first two digits of the cooling capacity.

(5) Split indoor unit structure code: W-Outdoor unit

(6) Improved code: divided into A, B, C, D, E, etc.

(7) Special function: BP-inverter

Example: KFR-35GW/BP indicates that it is a cooled and warmed wall-mounted split inverter air conditioner with a refrigeration capacity of 3,500w, which is a 1.5 HP Air conditioner.

Advantages of inverter air conditioning:

1. Power saving and energy saving:

As its compressor will not be turned on frequently, the compressor will be kept in a stable working condition, which can make the air conditioner overall to achieve the effect of energy saving of 15% -30%. At the same time, this is quite obvious to the reduction of noise and extend the service life of the air conditioner.

2. Low noise:

As inverter air conditioners run in balance, the vibration is reduced, and the noise is reduced. In our actual tests, compared with fixed-frequency air conditioning, the quiet performance of inverter air conditioning is really a step above.

3. Cooling speed:

When the difference between the room temperature and the withering temperature is large, the inverter air conditioner is turned on, that is, the maximum power to work, so that the room temperature quickly rise or fall to the adjusted temperature, the cooling (heating) effect is obvious.

4. Temperature control:

Inverter air conditioners can automatically adjust the compressor frequency according to the changes in the room cooling (heat) load, to reach the set temperature after the inverter air conditioning to a lower frequency operation, so that you can more accurately control the indoor temperature changes, a better sense of comfort.

● Inverter air conditioning shortcomings:

1. high price:

Compared with the general fixed-frequency air conditioning, inverter air conditioning has many advantages, but its price will also rise. After a period of popularity, I believe the price of inverter air conditioning will also fall.

2. Long time to recover the cost:

Inverter air conditioning, although energy-saving and power saving, because of the previous will be invested in an additional amount of money, so the recovery of costs has become a problem. Inverter air conditioning energy-saving effect will be based on different use of the environment and use habits to decide, so the recovery of costs will be longer.
