Interpretation of Energy Efficiency Improvement Technology, Comfort Experience Technology Application, and Selection Factors for Household Air Conditioning

First, the application of new technology

(1) Energy efficiency improvement:

The energy efficiency level of air conditioning is the smaller the number, the better, generally divided into new 1, 1, 2, 3 levels. And the new level 1 energy efficiency is the latest international energy efficiency standards in 2020, which is the best energy saving, of course, the price of air conditioning is also high, and it will save electricity when used in the future.

1, ultra-efficient shake block compressor: original shake block slide technology contact stress decreased 85%, friction coefficient decreased 87%, compressor energy efficiency increased 6%;

2, full DC frequency conversion technology:

(1) compressor motor technology: the use of modular multi-slot motor technology (12 slots 8 poles), electromagnetic vibration amplitude decreased, power density increased, reliability enhanced; High heat dissipation magnet air groove design, the motor anti-demagnetization ability increased by 30%;

(2) Full DC double rotor frequency conversion compressor: according to the indoor temperature, adjust  the speed of the compressor and fan, when the set temperature is reached, the compressor runs at low speed, and the temperature is relatively stable;

3, the whole continuous air injection enthalpy technology: no attenuation of heating capacity at -15 。C, air or water temperature at -25 。C continues to maintain above 55 。C, -35 。C normal operation;

4, constant air volume motor technology: intelligent sensing static pressure technology, adaptive adjustment of air volume, no sensor; Wide static pressure, ±3% high precision air volume control; Second response to ensure fast cooling and heating;

5, the second generation of R410A is widely used, the third generation of new refrigerant R32 and R290 into the pilot stage, improve the heat exchange efficiency at the same time, to meet the requirements of  environmental protection;

6, electronic expansion valve: according to temperature, humidity and other factors, take the initiative to  accurately control the flow of refrigerant, so as to ensure the stability and high efficiency of air conditioning operation.

(2) Comfortable experience technology:

1. Fresh air conditioning can introduce outdoor fresh air into the room, mix the cold air and natural wind in the tuyere to form a comfortable temperature for the human body and exhaust the indoor dirty air to achieve indoor air circulation and purification. Fresh air can be opened separately, regular fresh air can be reserved, H13 filter for PM2.5 single filtration efficiency of more than 99%; Fresh air check valve design,  prevent outdoor wind weather backpouring;

2, automatic detection and purification of PM2.5, three-color light ring display air quality;

3, no wind technology: no wind technology by adjusting the wind mode and wind speed, to avoid blowing the human body directly;

4, temperature and humidity dual control technology: the application of fuzzy control, PID control and other advanced technology, can automatically adjust the temperature and humidity of the air conditioner according to the change of indoor humidity;

5, anti-direct blowing function: according to the actual situation, automatically adjust the wind speed, operating frequency, air guide Angle, to prevent the air conditioning cold air blowing directly on the human body, to avoid causing physical discomfort. Carpet heating, air conditioning warm air close to the wall vertical to the ground slowly rise, so that the warmth from the feet throughout the body.

6, intelligent sleep control: through intelligent control of the temperature curve of the air conditioner at night, noise volume, screen display, etc., to ensure that the air conditioning can also have a good experience when sleeping at night.

(3) Intelligent:

1. Intelligent cleaning function: open the intelligent cleaning function of the air conditioner, automatically clean the internal fins, and remove bacteria at high temperature;

2, intelligent cream: according to the temperature of the pipe temperature change to determine the defrosting time, to achieve any situation can defrosting clean;

3, kitchen air conditioning: prepare the stage of the air conditioning automatically into 24 degrees of refrigeration, automatic wind speed; Stir-fry stage automatically into 18 degrees of refrigeration, strong wind state, wind deflector 30 degrees Angle, high frequency fast swing; Adjustable upper and lower wind, left and right wind, automatic memory of the wind direction;

(4) Integration: the air conditioning and display are integrated, the front is an LCD screen, the four sides are inlaid with a beautiful frame, and the air conditioning body is hidden behind the screen.

Second, home air conditioning purchase elements:

(a) It is recommended to choose new technology applications, new refrigerant and level 1 or 2 energy efficiency of the brand, such as full DC frequency conversion, self-cleaning technology, power saving technology, constant temperature control technology, intelligent sleep technology and remote intelligent connection technology;

(2) Appropriately buy a larger matching, to avoid not cold enough after installation, specific reference to the following figure:

Attachment: What is the reason why the newly installed air conditioner is not cold enough?

(3) Within the scope of noise, try to choose air conditioners with large circulation air volume; The

circulating air volume of the air conditioner is large, which means that the temperature difference between the air in and out of the outlet is small, but at the same time, it is also accompanied by large noise; The    small circulation air volume, the smaller the noise, but at the same time the outlet air temperature

difference is large;

(4) Compared with the air conditioner of the same brand manufacturer, the expensive air conditioner will still be relatively heavy, mainly because of the high density of copper tubes in the heat exchanger.

Between different brands, because the integration technology is not the same, it is relatively difficult;

(5) If the weight of the air conditioner is the same, the larger the size of the indoor unit and outdoor unit, the larger the corresponding heat exchanger area and fan diameter, the greater the corresponding heat

transfer capacity; In the case of the same heat exchange, the circulating air volume is small and the running noise is small.

(6) It is recommended to choose cylindrical cabinet air conditioning: up and down sweep, with left and right sweep, strong field control ability, fast temperature adjustment;

Third, if the installation position of the external machine, you need to buy central air conditioning, refer to: one trick to solve the design and selection of household central air conditioning

Fourth, pay close attention to home appliance chain stores, on-site experience and purchase! END!
