Expected future domestic central air conditioner market will still grow at an average annual rate of 20%. 1 household central air conditioning, household central air conditioning, the future facing greater development opportunities, household central air conditioning of meet the needs of high density residential villas and houses, because this product will use the advantages of room air conditioner and central air conditioning, has developed into a central air conditioning the new consumption hot spots, household central air conditioning will be another family air conditioning ZhiLengYe development trend. Suppliers according to the international mold and metal plastic industry association secretary general luo hui as a rough estimate, the next few years the domestic household central air conditioner market will present JiHeShu growth, annual average market capacity of about 10 billion yuan. 2, industrial and commercial air conditioning refrigeration equipment in addition to the household central air-conditioning, commercial and industrial refrigeration and air conditioning equipment is mainly including commerce, industry and transportation use refrigeration equipment and refrigerated container and niche products such as air conditioning market in bus and train. According to incomplete statistics, in 2008 China\'s industrial and commercial refrigeration and air conditioning equipment and its accessories market a total capacity of 135 billion yuan, compared with the central air conditioning market capacity is 35 billion yuan, account for only 25.93%. 3, home air conditioning switched commercial air conditioner field of commercial air conditioning in the future the huge market capacity and considerable profit space attracts many home appliance enterprises to enter. According to luo hui, the first-line brands such as gree, midea, haier, strong growth in household air conditioning at the same time, both with its products, technology, services, marketing network advantages, expand commercial air conditioning market aggressively, to provide users with more advanced, more reliable quality, service more perfect product. In terms of market, the four major brands, and Japanese two brands as a whole is still in the market leading position, but as China\'s three major brands have been among the commercial market, the overall technology level also gradually close to and surpass the international advanced level. Before entering the rapid development in the future, who can in the industry at the early stages of the commercial air-conditioning design, production technology, technological level and management ability, the late maintenance occupy the advantageous position, who will have a better chance in future commercial air conditioning market competition in a leading position. 4, cooling and refrigeration equipment with the logistics industry adjust and revitalization of planning \"and\" agricultural products cold chain logistics development planning and policy releasing, the ROM hundred hui cold-chain logistics market is expected the next ten years will be in the compound growth rate of 15.6% growth and will drive the rapid development of corresponding refrigeration equipment market. 5, high iron is special air conditioning with the development of high-speed railway in our country, the demand for high-speed train specialized air-conditioning will also continue to increase, and the field is still monopoly by foreign brand. Although with household air conditioning market and product there is a certain difference, but with its large domestic household air-conditioning manufacturers in the fields of professional refrigeration technology product accumulation, and sales and service channel advantage, is expected to enter the field to meet the growing market demand. Air conditioning technology development future will mainly revolve around the following six topics: frequency conversion air conditioning technology, energy saving, environmental protection, comfortable, quiet, intelligent network control. 1, frequency conversion air conditioning technology, frequency conversion air conditioning technology refers to the air conditioning inverter to control and adjust the speed of the compressor, remain the state of the best speed, so as to improve the stability of air conditioning can effect comparing and keep at room temperature. Frequency conversion air conditioning technology mainly along the how to use the lower minimum frequency and how to ensure the working state of the air conditioning in the low frequency under the condition of two aspects. Now in general use in the world at about 12 hz frequency conversion air conditioning of the lowest frequency, in use of outage probability is bigger, failed to give full play to the energy saving advantage of frequency conversion air conditioning; Increased at high frequencies at the same time the extra energy loss, high frequency of incompetence. Thus causing the low frequency power cannot give full play to the limited condition, high frequency operation frequency. Domestic enterprises such as gree electric appliances research and development of the G10 frequency conversion engine, USES the special custom control chip, self-developed compressor and fan motor, make compressor minimum frequency of 1 hz stable operation can be realized, represents the international advanced level in the field of frequency conversion. Frequency conversion air conditioning low frequency control technology mainly for frequency conversion air conditioning in room maintenance under the premise of constant temperature, the lower operating frequency, the less the consumed power, temperature fluctuation is small, so that the frequency conversion air conditioning energy-saving and comfortable character developed to get incisively and vividly. Frequency conversion air conditioning, however, the most widely used single rotor compressor on the market, in the low frequency run time due to large load fluctuation, the compensation measures must be taken. As rotating gyro, must exert force during low speed, to ensure stable operation. How to solve the problem of single rotor compressor low frequency vibration is one of the key technical problems in air conditioning industry, gree electric appliances research and development of an adaptive torque control technology solved this problem completely, identified by experts as the international leading level. 2, improve the efficiency of energy saving of refrigeration air conditioner refrigeration efficiency mainly by three measures implemented, one is the application of high efficiency compressor and compressor control technology, the second is strengthening in thermal efficiency, the third is the organic combination of intelligent control technology and air-conditioning refrigeration system makes the air conditioner run in optimal state. High efficiency compressor is the use of dc or fixed frequency varactor compressor frequency conversion technology to improve the energy efficiency of air conditioner. Scroll through the vortex disk load and unload two states of different cycle time implements the refrigeration efficiency, mechanical control instead of the complex electronic control frequency conversion technology, because of the advantages of reliable operation, low cost, get a batch of air-conditioning manufacturers, gree electric appliances, and other enterprises will be digital vortex varactor system as an important technical route of compete with variable frequency system and intensify research. In 2009, gree electric appliances & quot; Heat recovery digital split air conditioning unit & quot; Passed the national torch plan, has the characteristics of high efficiency, environmental protection and energy saving. Improved thermal efficiency in technology mainly reflected on the heat exchanger, heat exchanger is performance-based and reduce the cost of the industry\'s research priorities. At present industry generally from strengthen heat transfer, heat transfer coefficient and pressure loss, the loss of pressure shunt and heat exchanger design, compressive strength and other aspects detailed argument using small diameter to replace of common heat exchanger, heat exchanger so as to achieve high performance processing for heat exchanger and the low cost of harmonious unification, saving large amounts of copper and refrigerant, accord with national energy-saving emission reduction policies. 3, environmental protection and safety of freon is air conditioning refrigerants, refrigerant generally said, freon is known to have damage to the ozone layer, air conditioning refrigerant has chlorofluorocarbons (CFCS), hydrogen CFCS (HCFCS) and HFC (HFCS), etc., including CFCS serious damage to the ozone layer, has banned the use; HCFCS also have damage to the ozone layer, such as R22; HFCS zero ozone layer destruction, more environmental protection, such as R407c, R410A. International study of R22 refrigerant alternatives there are 2 different technical route, a represented by Japan, support development HFCS substitutes; A represented by Germany and the Nordic countries, promote hydrocarbons in natural cooling as substitutes. Common practices in the industry at present is to use HFCS refrigerant, such as replace R22 as air conditioning refrigerant R410A, although R410A does not destroy the ozone layer, but it still has the effect of greenhouse gas emissions, there are still certain influence to the environment. So the industry is still in the research and development new refrigerant, and strive to do not destroy the ozone layer, and will not result in climate warming. Domestic enterprises such as gree electric appliances actively develop environmental protection refrigerant, such as substitute R290 and R32 for R22 and R410A. Considering the nature the refrigerant has flammable explosive, security problem is the design, production, use and maintenance of the primary problem must be considered, adopting the explosion-proof components, electrical and other kinds of components is a way. In addition, the refrigerant such as when used in home air conditioning also need to face the refrigerant leaks to the interior of the safety problems. In view of the above situation, gree electric appliances is also working on new cold media hot and cold water unit, including air-cooled hot and cold water heat pump, heat pump water heater, etc., the indoor unit can avoid the refrigerant into the users, can be done to avoid risk of refrigerant leakage. 4, high comfort and indoor air quality, improve product comfort around the temperature control and humidity control, optimize the indoor air distribution, adopting reasonable control mode, in the human body thermal comfort at the same time, achieve the goal of energy saving. Use features include comfort and energy saving control mode, new/sweep the wind guide plate structure, new type air supply way, a water/free water humidification, etc. Improve indoor air quality is mainly through the use of antibacterial, mildew proof materials, antibacterial, mouldproof) filter, the negative/plasma generator, electrostatic precipitator, increases oxygen ventilation parts, components, such as antimicrobial, in addition to smell, the purpose of removing indoor harmful pollutants. 5, mute mute design of air conditioning is a system engineering, not only to design a voice part of the low noise compressor, motor, fan, air duct, electric heating tube, the wind components and wind components, piping system, shell structure, more to the possible noise component and heat exchange system design, control technology, material selection, process integration, make the machine run good matching condition, realizing the quiet operation. Mute technology challenge comes from: around the house, light panels, and the miniaturization of outdoor and frequency of consumption trend. Technology includes the following aspects: CFD duct design optimization technology, environmental mute technology on the basis of comfortableness research, based on two-phase flow distribution study of noise reduction technology and compressor noise reduction technology, etc. Related research has achieved obvious results, domestic bedroom air conditioning series mute performance has reached the industry leading level. 6, intelligent network control by mobile phone short message, mobile phone software, telephone remote control, remote means such as Internet, electric control air conditioning, the air conditioning running state, images, information related to security, and the air conditioning running state, power line, through the network of the electromagnetic wave back to the user. Humidifying linkage, independent of the humidifier and the air conditioning work together, to ensure comfort. Doors, Windows, when judge the natural wind meet the demand of comfort, intelligent shutdown window, in order to make the best use of natural environment temperature, power saving, comfortable and convenient.
