From there it is possible to tell whether the air conditioner is good or bad 40

Refrigeration (heat) refers to the amount of heat removed from a confined space by an air conditioner in a unit time of refrigeration (heat) operation, and the legal unit of measurement is w (watts). The national standard stipulates that the actual cooling capacity of the air conditioner should not be less than 95% of the rated cooling capacity.

The energy efficiency ratio, also known as the coefficient of performance, refers to the ratio of cooling capacity to cooling power when the air conditioner is running for refrigeration, in W W.

The national standard stipulates that the standard value of the energy efficiency ratio of 2500W air conditioner is; The standard value of energy efficiency ratio of 2500W to 4500W air conditioner is:

Noise refers to the noise generated when the air conditioner is running, mainly generated by the internal evaporator and the external condenser.

The state stipulates that the noise of the indoor unit of the air conditioner with a cooling capacity of less than 2000W shall not be greater than 45 decibels, and the noise of the outdoor unit shall not be greater than 55 decibels; The noise of the indoor unit of the split air conditioner from 2500W to 4500W is not more than 48 decibels, and the noise of the outdoor unit is not more than 58 decibels.

Almost all of the air conditioners installed in our community are Midea, the quality is not bad, there is little maintenance, the installation is very good, and the after-sales installation staff of Midea is very professional. The 2 units I use at home are beautiful, the quality is very satisfactory, the noise is low and the power saving.

Measure the temperature difference between the air inlet and outlet of the air conditioner, and in the case of high air gear, the difference should be at least 12 degrees.

The best way to identify an air conditioner is as follows: 1. Look at the refrigeration (heat) amount. The heat removed from the confined space by the air conditioner in the unit time of refrigeration (heat) operation, the legal unit of measurement w, the national standard stipulates that the actual cooling capacity of the air conditioner shall not be less than 95 of the rated cooling capacity.

2. Second, look at the energy efficiency ratio. Energy efficiency ratio, also known as coefficient of performance, refers to the ratio of cooling capacity to refrigeration power when air conditioning and refrigeration are running. The national standard stipulates that the standard value of the energy efficiency ratio of 2500W air conditioner is; The standard value of energy efficiency ratio of 2500W to 4500W air conditioner is, at present, it is an energy consumption ratio that must be achieved by first-class energy efficiency air conditioner.

3. Third, look at the noise level. The noise generated when the air conditioner is running is mainly generated by the internal evaporator and the external condenser. The state stipulates that the noise of the indoor unit of the air conditioner with a cooling capacity of less than 2000W should not be greater than 45 decibels, and the outdoor unit should not be greater than 55 decibels; The noise of the indoor unit of the split air conditioner from 2500W to 4500W is not more than 48 decibels, and the noise of the outdoor unit is not more than 58 decibels.

Do you have any other questions?

Approaching the hot summer, it is the peak season for air conditioning sales, and it is also the peak period for consumers to buy air conditioners. Many consumers are often confused when faced with a variety of products in the store, what kind of air conditioner is worth buying? What kind of products are worth buying for consumers?

What are the characteristics of the products that can see the advantages and disadvantages of air conditioners?

With these questions, Moon Rabbit brought you ten standards for testing the advantages and disadvantages of air conditioners.

1. Whether to use a brand-name compressor, the compressor is the heart of the air conditioner, and a good heart is of course important.

2. Whether to use high-quality and efficient heat exchangers, such as hydrophilic membrane trapezoidal aluminum re-entry sheets, internally threaded copper pipes, etc.

3. Whether to use a large wind wheel with no finger leakage or equidistant cross-flow fan blade and step-driven wind pendulum to achieve ultra-quiet design.

4. Whether it is super forced cold (hot) and quickly reaches the set temperature.

5. Whether the appearance of the product is beautiful and whether it is harmonious and unified with the home environment.

6. The cooling (heat) capacity of the product, choose the appropriate cooling (heat) capacity according to the area of the room.

7. Whether the product is power-saving, generally speaking, the higher the refrigeration (heat) capacity, the lower the input power, the more power-saving the product.

8. The length of life. Whether it adopts microcomputer fuzzy control to achieve non-stop operation, whether it can be automatically defrosted.

9. Look at the noise index of the product.

10. Whether there is a low voltage automatic compensation function and a wide voltage working range.

Through the above subtle differences, you can better understand the quality of an air conditioner.

Summary. Look at the cooling capacity and heating For a good quality air conditioner, whether it is heating or cooling, the effect is good, while the poor quality is likely to not achieve a good use effect. Normally, its cooling capacity should not be less than 90 percent.

How to identify the *** bad of an air conditioner.

Look at the cooling capacity and heating For a good quality air conditioner, whether it is heating or cooling, the effect is good, while the poor quality is likely to not achieve a good use effect. Normally, its cooling capacity should not be less than 90 percent.

1. Pay attention to the appearance: the air conditioner should be clean and tidy, the surface of the shell should be free of foreign matter or wear, and the outer frame should be decorated with decorative paper or spraying; 2. Check the electrostatic effect: toggle the air conditioner switch, touch the condenser shell with your hand, if there is a violent "click" sound and a sharp feeling, the air conditioner refrigeration effect is obvious, indicating that the quality of the air conditioner is at least okay; 3. Pay attention to noise:

The sound of air conditioning should be as low as possible, the normal sound of air conditioning is generally not more than 45 decibels, and the sound of high-end air conditioning can be less than 35 decibels; 4. Investigate the speed of cold and heat: the operation of the air conditioner can be completed in a few seconds to switch the cold and hot mode, the faster the speed, the better the quality, the more uniform the space temperature, especially the smaller the temperature difference when switching to the cold mode, no cold wind and no condensation; 5. Trial operation time: under normal circumstances, the air conditioner can run for about 3 hours when it is fully open or fully closed, which is more reliable and more power-saving, and check the air conditioning outlet grille, if it is solid and reliable, it is not easy to fold and not easy to deform, indicating that the quality of air conditioning materials is guaranteed.

What brand of air conditioner, kiss <>

Gree air conditioner. Energized inspectionFor the integral air conditioner, the following items can be checked by energizing: 1. Refrigeration:

In summer, you can test the refrigeration function of the air conditioner, turn down the temperature control value, turn on the power for a few minutes, and there should be cold air out; 2. Heating: buy an air conditioner in winter or when the temperature is low, and you can try to make hot air function; 3. Wind speed: adjust the wind speed selection button, there should be different air volume blowing out.

6. Noise and vibration inspection: When the air conditioner is in refrigeration movement, there can be no abnormal impact sound and other noise, and the vibration should not be too large. 7. Check the electrical performance to check whether the power cord and power plug meet the specifications, and the power cord should not be loose or pulled out if you pull it hard. If possible, the cold insulation resistance of the air conditioner can be measured.

In fact, the brand of Gree air conditioner is good.

Generally there are no quality problems.
