How to choose an air conditioner at home? Do you have any opinions?

Generally, buying an air conditioner is to consider the refrigeration area, energy efficiency, power, power consumption, etc., and then look at the brand's comprehensive strength, product quality, word-of-mouth evaluation, etc. Specifically, you can go directly to the brand's store to consult with the sales staff. When it comes to buying things, the main thing is to suit yourself, just like it!

The new house at home is also being renovated, and the Mitsubishi Heavy Industries ** air conditioner was chosen, which was just installed two days ago, and the overall shopping experience is still very OK. The installation master is numb, and he is an "old driver" at a glance, and the installation technology is very solid, and it will be installed after a while.

For R22 refrigerants, R410A has zero damage to the ozone layer, but its greenhouse gas effect even partially exceeds that of R22. Therefore, R410A is not the ultimate environmentally friendly refrigerant solution for China's air conditioning industry. The R410A is just a transitional replacement.

At present, the refrigerant used more in China's air-conditioning industry is very close to the basic physical properties such as the standard boiling point, freezing point and critical point of R22, and has the basic conditions to replace R22. In the saturated liquid state, the density of R290 is smaller than that of R22, so the perfusion volume of R290 is smaller under the same volume, and the perfusion volume of R290 under the same system volume is about 43% of that of R22. In addition, since the latent heat of vaporization of R290 is about twice that of R22, the refrigerant circulation of refrigeration systems using R290 is smaller.

R290 has good material compatibility, and can be well compatible with copper, steel, cast iron, lubricating oil, etc. Although the R290 has the above advantages, its "flammable and explosive" disadvantage is currently the biggest obstacle that limits its large-scale promotion. R290 can be mixed with air to form a first-class mixture, which has the risk of burning when exposed to heat sources and open flames.

Ways to improve the safety of R290 include reducing the filling volume, isolating the ignition source, preventing refrigerant leakage, and improving the safety prevention and control ability after leakage. What is certain is that with the expiration of the R410A patent, the cost will drop significantly, and in the coming years, the R410A refrigerant will become mainstream.

What you have learned before will not become obsolete, but you need to be more careful in your operation!

1. Choose the number of horses of the air conditioner correctly

The approximate relationship between the number of horsepower and the cooling capacity is as follows:

The energy efficiency of different types of air conditioners is different, and the higher the energy efficiency, the higher the unit cooling capacity. The energy efficiency of air conditioning in China is divided into 5 levels, with level 1 being the highest, and the energy efficiency ratio is above, and the higher the level, the more power saving.

The approximate relationship between the room area and the number of air conditioners is: number of horses = area 2 25.

So, a 10 square meter room (10 2 25 = choose 1 horse (or small 1 horse) air conditioner will do.

A room of 15 square meters (15 2 25 = then requires air conditioning.

If the number of horsepower of the air conditioner is too large, the air conditioner will start frequently, and it will be hot and cold, which will affect the comfort. Therefore, be sure to choose the right air conditioner according to the room area.

1. To equip the home with air conditioning, you can't just look at the number of horses, but also look at the cooling capacity.

2. The formula for calculating the cooling capacity of the room: the cooling capacity of the room per unit of cooling capacity x the area of the room.

Second, the inverter air conditioner fixed frequency air conditioning selection

Fixed-frequency air conditioners will not work all the time and will rest, and the advantage is that the durability is low. Inverter air conditioning is working all the time, so the indoor temperature control is better, the advantage of inverter air conditioning is that it can accurately control the temperature and size of the air outlet, not only energy saving but also noisy, in the time of sleep will be very comfortable, but the disadvantage is that the ** will be relatively high.

Precautions for turning on the air conditioner.

1. Before turning on the air conditioner, we need to open the window to ventilate it first, so that the indoor air is fresher, and then we close the doors and windows, so as to make the cooling or heating effect better, and will not make the heat or cold flow out.

2. If you choose an inverter air conditioner in your home, when adjusting to the refrigeration mode, you can first set the air conditioner in a state of strong operation, and the temperature difference between indoor and outdoor is about 4 5 degrees, which will be more appropriate. Both the temperature and the wind speed are more suitable for the human body, and it can also achieve the effect of rapid cooling and energy saving.

3. Many people like to blow the wind directly at people when they turn on the air conditioner, and often blowing like this will cause people to catch a cold. And if the filter of the air conditioner is not cleaned, there are many impurities in the air blowing, which will also affect the respiratory tract of the human body.

4. Since the air conditioner is turned on, no matter what season it is, don't smoke indoors. Once the air conditioner is running, it can extract the indoor air, but the smoke and air mix together, which will cause the air conditioner to emit odors, which will also affect the health of the family.

Look at how many square meters of the place where you want to install an air conditioner at home, just buy an air conditioner that is suitable for a few P in your home.

How to choose an air conditioner at home? When you buy a household air conditioner, the key is to see whether the brand is the first or second line in China. If the funds allow, foreign brands can also be considered. Of course, you can't just look at the brand, you also need to check how the reputation of the brand is.

How to choose an air conditioner at home? Household air conditioners have ordinary air conditioners, as well as ** air conditioners. Both types of air conditioners have their advantages and disadvantages, users can choose according to their own needs, if it is a large area, ** air conditioning can allow the entire floor to enjoy cool cold air.

The ordinary household air conditioner is suitable for the public family, which is economical, easy to install, and convenient for later maintenance.

Air conditioners are more affordable to buy cheap, air conditioners are household appliances that consume electricity, and it is necessary to avoid the misunderstanding of spending less money to buy cheap. If you spend more money to save electricity when you buy it, you will save much more money on electricity bills in the future than you will spend more money on it.

When installing air conditioners, we must do a strict inspection of the formality of the air conditioning company, and find the wrong place to find the business to deal with it in time, so as not to cause unnecessary impact and harm to your family and housing in the future.

SH Huichi (Huichi-China).

If you choose it in the living room, of course, you should choose a larger vertical air conditioner, and if you choose it in a separate room, I think the hanging air conditioner is enough.

Hanging air conditioners are widely used, and can be used in bedrooms and living rooms. Cabinet air conditioner is a type of split air conditioner, which is generally used in homes.

1. When buying an air conditioner, you should know how big your room is and how much space it is, so as to choose the size of the air conditioner2. If it is used in the bedroom, choose the hanging type, which can save space, and the living room, you can choose the cabinet air conditioner if the area is large3. Choose a brand, what brand to choose can make the final decision according to your preferences and economic level, it is best to choose a well-known big brand, which is more safe and reliable

4. Look at the energy efficiency ratio of the air conditioner, it will generally be pasted on the surface of the machine, the higher the energy efficiency, the better, and the more energy-saving, of course, the higher.

The main thing is to look at the number of horses, if you want to save electricity, you have to look at the frequency conversion and energy efficiency, my family now uses Haier's inverter first-class energy efficiency air conditioner, I feel that it is much more energy-saving than the fixed frequency used before, although the frequency conversion is more expensive than the fixed frequency, but like us, the use of a long time, slowly will be saved.

I like the self-cleaning function, the air in the house is always clean

The general cooling load index (cooling capacity per square meter) is more suitable from 110W to 220W.

Considerations: room size, orientation, floor height, number of occupants.

Sunny and poorly ventilated rooms should appropriately increase the cooling capacity of the equipment.

Definition of Air Conditioner Horsepower:

The number of air conditioners originally refers to the input power, including the compressor, fan motor and electronic control part, and the refrigeration capacity of different brands is different when the same input power is used, so the cooling capacity should be calibrated by the output power.

How many horsepower is the air conditioner and what does it mean?

HP does not refer to cooling capacity, but refers to power consumption, 1 HP = 1 HP = 735W.

A horsepower air conditioner refers to the cooling capacity that can be generated by inputting 1 horsepower, and the magnitude is related to the energy efficiency ratio EER.

Under normal circumstances, the refrigeration capacity of 2200-2600W is called one horse, and 3200-3600W is the ...... horseHow is it calculated?

1 hp = 2500w Strictly speaking, it is 2499w, which was first proposed by the Japanese.

1 horsepower = 735W, if the energy efficiency ratio is.

1 hp = 735*.

People are accustomed to use 1 horsepower of about 2500w cooling capacity (that is, 25 models) and horsepower about 3500w cooling capacity (that is, 35 models) to represent the model of air conditioner. The rest of the models can estimate the number of horsepower in this way.

The model of the air conditioner.

Installation: hang-up, cabinet, floor-mounted, embedded ......

Cooling and heating types: single cooling, heat pump, electric auxiliary heating, electric heating.

Compressor type: fixed frequency, variable frequency, variable capacity.

Power supply: 220V, 380V

Refrigerants: R410A, R407C, R134A......

Energy efficiency class: Level 1, Level 2, Level 3 (access).

Classification of energy efficiency of air conditioners.

Energy efficiency ratio or above: energy efficiency level 1.

Energy efficiency ratio: energy efficiency level 2.

Energy efficiency ratio: Energy efficiency level 3 (entry level).

Energy efficiency ratio: energy efficiency level 4 (eliminated).

Energy efficiency ratio: energy efficiency level 5 (eliminated).

according to the size of your home.

Hello, there are a few key points to pay attention to to look at the appearance: Visual inspection of each part of the air conditioner, should be finely processed, the surface of the plastic parts is smooth and smooth, and the color is uniform. The surface of the electroplating parts should be smooth, and there should be no defects such as peeling, exposed bottom, scratches, etc.

There should be no bubbles, flow marks, missing coating, exposed primer layer, and uneven unevenness on the surface of the sprayed parts. The installation of each component should be firm and reliable, and the pipeline and the components should not rub or collide with each other. Positioning:

Vertical and horizontal wind deflector inspection. The manual vertical and horizontal wind deflector should be able to be toggled up and down or left and right, not too tight, not too loose, should be dialed in any position can be positioned, should not be automatically shifted. **：

Midea and Gree air conditioners are all first-line well-known brands, because the consumption level is different across the country, so there will be a certain gap, and different brands have different technical advantages, so the sales will be different. Filter: The filter is a component that is often disassembled and assembled, and it should be checked whether it is convenient to disassemble and assemble, whether it is damaged, etc.

Function buttons: Check the knobs on the panel of the air conditioner for each function key and knob to rotate flexibly, fall in place, not loosen or slide. The function selection buttons on the computer-controlled air conditioner, remote control, and wire control are light and flexible, and there must be no stuck keys.

Based on the above, it is concluded that when choosing an air conditioning brand, there are many types of air conditioners on the market, if you don't pay attention to it when you choose, you will buy inferior products, and the buyer will not only feel uncomfortable, but also cause economic losses. Therefore, when choosing, it is necessary to think from many aspects.

When buying an air conditioner, you need to consider various factors, such as **, style and saving points. How to buy an air conditioner at home? PChouse will take you to find out.

1. The area of the house determines the number of air conditioners.

Usually a small air conditioner is suitable for use in a space of 12 square meters for 1-2 people. 1 HP air conditioner is suitable for use in a space of 16 square meters for 2-3 people; The air conditioner is suitable for the number of people in a space of 20-23 square meters and 4-5 people. The larger the number of people and the larger the size of the house, the greater the number of horses that need to be selected for air conditioning.

Second, the frequency conversion and fixed frequency determine whether to save power.

The fixed-frequency air conditioner will stop and start during use, consuming more power, while the inverter air conditioner will switch to low-frequency operation after reaching the set temperature. Although the air conditioner is still consuming electricity, it consumes very little power and does not consume power by restarting the compressor. Therefore, using an inverter air conditioner will save more electricity than a fixed-frequency air conditioner.

At the same time, inverter air conditioning will make the indoor temperature more constant and increase the comfort of use.

Third, the choice of air conditioning model.

There are outward-facing windows, the structure is sturdy, suitable for good ventilation, and window air conditioning should be chosen. There are no outward-facing windows, or the basket structure is not suitable. Pay great attention to the appearance, require the air conditioner to be installed in a less conspicuous place, not suitable for the installation of window air conditioning, should choose split air conditioning.

Fourth, level 3 energy efficiency is more cost-effective.

Experts simulated the use of air conditioning for 5 hours a day and cooling for 90 days a year. The electricity cost of a grade 1 energy efficiency inverter air conditioner is about 178 yuan a year, and the electricity cost of a grade 3 energy efficiency inverter air conditioner is about 221 yuan a year. If consumers do not use air conditioners for cooling half of the day in the summer, it is more cost-effective to choose a level 3 energy efficiency inverter air conditioner.

Here are a few factors you can consider when choosing a home air conditioner:

1.Room size: Determine how big of a room you need to cool. The size of the room determines the cooling capacity of the air conditioner, and choosing the right size air conditioner can ensure the comfort of the room.

2.Energy efficiency: It's important to focus on energy efficiency because energy consumption has a direct impact on your energy bills. Finding and comparing an air conditioner's energy efficiency rating, often expressed in energy star ratings, can help you choose a more energy-efficient air conditioner.

3.Noise level: Noise level is an important consideration for air conditioners used in residences. Find and compare the noise levels of air conditioners to help you choose a quieter product.

4.Brand and reliability: Choosing an air conditioner from a trusted brand can provide better quality assurance and after-sales service. Researching user reviews and word-of-mouth across brands can help you make a more informed choice.

5.Additional features and functions: Some air conditioners may have additional features and functions, such as air purification technology, humidity control, and smart controls, among others. Depending on your individual needs and budget, you can consider whether you need these extra features or not.

Finally, filter some of the available air conditioning models according to your specific needs and budget, and go to physical stores or ** platforms as much as possible to compare, consult, and seek professional advice before purchasing.
