Parts production-central air conditioning assembly-central air conditioning sales-central air conditioning engineering installation-engineering consumables production (air ducts, insulation materials, water pipes, valves, etc. )-central air conditioning maintenance-central air conditioning energy-saving transformation. ........

The whole industrial chain is very long.

Question 4: Which industries is the central air-conditioning industry related to? 30 points 1. For sales representatives, sales knowledge is undoubtedly necessary. Sales without knowledge can only be regarded as speculation and can't really experience the fun of sales.

2. Successful promotion is not an accidental story, but the result of sales representatives learning, planning and applying knowledge and skills.

3. Promotion is the application of common sense, but only by applying these concepts that have been proved by practice to the "action school" can it produce results.

Before you make a splash, you must be prepared for boredom.

5. Never neglect the preparation and planning before promotion, only when you are prepared can you win. Prepare sales tools, opening remarks, questions to ask, words to say and possible answers.

6. The combination of sufficient preparation in advance and inspiration on the spot often leads to the disintegration of a powerful opponent and success.

7. The best sales representatives are those who have the best attitude, the richest commodity knowledge and the most thoughtful service.

8. We must learn and remember the materials, brochures and advertisements related to the company's products. At the same time, we should collect competitors' advertisements, promotional materials and brochures, study and analyze them, so as to "know yourself and know yourself" and truly know yourself and know yourself, and then we can take corresponding countermeasures.

9. Sales representatives must read more books and magazines about economy and sales every day, especially newspapers, understand national and social news and news events, and visit customers every day. This is often the best topic, and it will not appear ignorant and shallow.

10. The way to get orders begins with finding customers. Cultivating customers is more important than current sales. If we stop adding new customers, sales representatives will no longer have a source of success.

1 1. A transaction that is unfavorable to customers is bound to be harmful to sales representatives, which is the most important business ethics.

12. When visiting customers, the principle that sales representatives should believe in is "grab a handful of sand even if you fall". This means that the sales representative can't go home empty-handed. Even if the promotion is not over, ask the customer to introduce you to a new customer.

13. Select customers. Measure customers' willingness and ability to buy, and don't waste time on indecisive people.

14. The important rule of a strong first impression is to help people feel important.

15. Be punctual for appointments ―― Being late means "I don't respect your time". There is no reason for being late. If you can't avoid being late, you must call and apologize before the appointed time, and then continue the unfinished sales promotion work.

16. Sell to Mr. Power who can make a purchase decision. If your sales partner has no right to say "buy", you can't sell anything.

17. Every sales representative should realize that sales can be successful only if you keep an eye on your customers.

18. Getting close to customers in a planned and natural way and making customers feel that smooth negotiation is beneficial is the work and strategy that sales representatives must work hard to prepare in advance.

19. It is impossible for a sales representative to reach a deal with every customer he visits. He should try to visit more customers to increase the percentage of transactions.

20. Know your customers, because they decide your performance.

2 1. Before becoming an excellent sales representative, you should be an excellent investigator. You must discover, track and investigate until you know everything about your customers and make them your good friends.

22. Believe that your product is a necessary condition for a sales representative: this confidence will be passed on to your customers. If you have no confidence in your product, your customers will naturally have no confidence in it. Customers are talked about not so much because of your high logical level, but rather because of your deep confidence.

23. Excellent sales representatives can tolerate failure partly because they have confidence in themselves and the products they sell.

24. Know your customers and meet their needs. Not knowing the needs of customers is like walking in the dark, wasting energy and not seeing the results.

For sales representatives, nothing is more precious than time. Knowing and choosing customers is to let the sales representative focus his time and energy on the most likely customers, instead of wasting it on people who can't buy your products.

26. There are three rules to increase sales: pay attention to your important customers, pay more attention, and pay more attention. ...& gt& gt

Question 5: What industry category does the maintenance of central air conditioning belong to? The general manager of Shijiazhuang Bi Haubert Environmental Protection Engineering Co., Ltd., a designated enterprise in indoor air testing, Shijiazhuang, tells you the key points of air conditioning purchase: a good air conditioner can last for ten years, and the price is not low. Therefore, buying air conditioners must not be cheap. Buying air conditioners depends on product quality:

1. Whether to use a famous brand compressor, the compressor is the heart of air conditioning, and a good heart is of course important.

2. Whether to use high-quality and efficient heat exchangers, such as hydrophilic film trapezoidal aluminum sheets and internally threaded copper tubes.

3. Whether to use large wind wheel with unequal cross-flow blades and stepping motor to drive the wind pendulum to realize ultra-quiet design.

4. Whether it is super cooling (heating), quickly reach the set temperature.

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

6. Refrigeration (heat) quantity of the product, and choose the appropriate refrigeration (heat) quantity according to the area of the room.

7. Does this product save electricity? Generally speaking, the higher the cooling capacity (heat), the lower the input power, and the more energy is saved.

8. The length of life. Whether to use microcomputer fuzzy control to realize non-stop operation and whether to defrost automatically.

9. Look at the noise index of the product.

10. Whether there is low voltage automatic compensation function and wide voltage working range. In addition, when buying an air conditioner, you must see that the fins of the evaporator and condenser are arranged neatly, the fins are not damaged, and the fins are closely connected with the copper tube without looseness. Check the operation of the air conditioner, start the air conditioner, and check whether there is abnormal noise in the operation of the compressor; The fan operates normally, with obvious difference between high, medium and low speed and low noise; There is also a flat appearance, beautiful appearance and good quality of plated parts.

1 1. Try to choose low-carbon air conditioners to reduce carbon emissions, implement low-carbon environmental protection and protect the earth.

In principle, there are many air-conditioning brands in the brand market, domestic and foreign, and most of them have their own unique advertisements, so it is difficult for consumers to choose. It is suggested that when purchasing air conditioners, choose products with strong enterprise strength, high brand awareness and perfect after-sales service.

This is based on two considerations. The first is to ensure the implementation of after-sales service, because air conditioning is a household appliance and after-sales service is very important. According to the relevant national regulations, the compressor should be guaranteed for 3 years, and the competition in the home appliance market is almost fierce. Some manufacturers often have a short life cycle, and some collapse in three to five years. When an enterprise goes bankrupt, its promise will naturally be difficult to realize. Greedy and cheap, buy products with weak enterprise strength and low brand awareness, and there will be endless troubles. Secondly, consider the quality, because the quality of air conditioners with strong enterprise strength and high brand awareness is relatively stable. Such enterprises not only have strong technical strength, but also pay special attention to quality, so the quality of such products is guaranteed. After consumers choose the brand of air conditioner, they decide where to buy it. When buying an air conditioner, it is particularly important to choose a merchant. Because strictly speaking, the air conditioner is a semi-finished product, which can be used not after being bought from the store, but after being installed and debugged by a professional team. If the installation and debugging are not good, it will bring a series of problems, such as poor ventilation, water leakage of pipe joints, human failure during debugging and so on. These will not only affect the use effect, but also add a lot of trouble. At the same time, many after-sales service measures of manufacturers also need to be implemented and implemented by merchants. Therefore, it is very important to choose a good merchant. As for the choice of merchants, people in the industry suggest that those big merchants with strong local strength and influence should be chosen first, because these merchants have many kinds of business and sales, and generally have professional installation and debugging teams, with guaranteed installation and debugging quality and perfect after-sales service.

Secondly, choose those businesses that sell air conditioners for a long time, and try not to buy them from short-term dealers, because such dealers' after-sales service will be greatly discounted. Buying air conditioners by measuring rooms is a kind of high-consumption household appliances. If the selected power is too small, it will not work. Too much power is wasted.

Therefore, when consumers choose the power of air conditioning, they should measure the room to buy.

First, don't be greedy. Some consumers like to buy large air conditioners, which is not desirable, because except for some special factors, household air conditioners have their scope of use. Consumers should choose the type of air conditioner according to the area of their room when purchasing. In general, the required cooling capacity and heating capacity of a room can be calculated according to the following formula. Cold storage area × 140W to180w; Heating room area × 180W to 240W. In addition, it should be increased or decreased according to the orientation, height and sealing degree of the room.

The second is to choose according to the design of the room flexibly. Don't buy a large air conditioner in the living room to save the room like some families do. This will not only make it difficult to keep the room, but also cause waste. The reasonable way is to buy some low-power air conditioners according to the room type and manage each room.

Question 6: What is the business scope of the HVAC industry? Are you a rich second generation with a score of 15? It is awesome to register an equipment company without knowing it.

You can write like this. I don't know what the equipment strength of your company is.

The company is a professional HVAC technology company integrating the sales, design, installation and after-sales of air conditioning, heating, ventilation, fire fighting and smoke control equipment.

Question 7: What are the industries related to air conditioning? I don't know which one you are talking about, raw materials or something else.

The raw materials are mainly compressors, motors, copper pipes, computer boards and steel plates.

If these are blessings, of course, there are many more!

Question 8: What are the main new technologies in the refrigeration and air conditioning industry in China? The single-stage vapor compression refrigeration system consists of four basic components: refrigeration compressor, condenser, evaporator and throttle valve. They are connected in turn through pipes to form a closed system, in which the refrigerant continuously circulates, changes state and exchanges heat with the outside. After absorbing the heat of the cooled object in the evaporator, the liquid refrigerant vaporizes into low-temperature and low-pressure steam, which is sucked by the compressor, compressed into high-pressure and high-temperature steam, and then discharged into the condenser, where it releases heat to the cooling medium (water or air) and condenses into high-pressure liquid, which is throttled into low-pressure and low-temperature refrigerant by the throttle valve, and then enters the evaporator to absorb heat and vaporize, thus achieving the purpose of circulating refrigeration. In this way, the refrigerant in the system completes a refrigeration cycle through four basic processes: evaporation, compression, condensation and throttling. In the refrigeration system, evaporator, condenser, compressor and throttle valve are four essential components in the refrigeration system, among which evaporator is the equipment for conveying cold energy. The refrigerant absorbs the heat of the cooled object to realize refrigeration. The compressor is the heart, which plays the role of sucking, compressing and conveying refrigerant vapor. The condenser is a device for releasing heat, which transfers the heat absorbed by the evaporator and the heat converted by the compressor to the cooling medium. The throttle valve can throttle and decompress the refrigerant, and at the same time control and adjust the amount of refrigerant liquid flowing into the evaporator. The system is divided into two parts: high pressure side and low pressure side. In the actual refrigeration system, in addition to the above four components, there are often some auxiliary equipment, such as solenoid valve, distributor, dryer, heat collector, fusible plug, pressure controller and other components, which are set to improve the economy, reliability and safety of operation. Air conditioners, which are composed of the main components of the refrigeration system, can be divided into water-cooled and air-cooled types according to the condensation form, and can be divided into single-cooling and refrigeration heating types according to the purpose of use. No matter what type of structure, it is composed of the following main components. 1. The main components of the refrigeration system are compressor, condenser, evaporator, expansion valve (or capillary tube, supercooling control valve), four-way valve, compound valve, one-way valve, solenoid valve, pressure switch, safety plug, output pressure regulating valve, pressure controller, liquid storage tank, heat exchanger, heat collector, filter, dryer, automatic switch, stop valve, liquid injection plug, etc. 2. The main components of the electrical system are motors (used for compressors, fans, etc.). ), operating switch, electromagnetic contactor, interlocking relay, overcurrent relay, thermal overcurrent relay, temperature regulator, humidity regulator, temperature switch (used for defrosting, antifreeze, etc. ). Compressor crankcase heater, water cut-off relay, computer board and other components. 3. The control system consists of several control devices, which are: refrigerant controller, expansion valve, capillary tube, etc. Refrigerant loop controller: four-way valve, one-way valve, compound valve and solenoid valve. Refrigerant pressure controller: pressure switch, output pressure regulating valve and pressure controller. Motor protectors: overcurrent relay, thermal overcurrent relay and temperature relay. Temperature regulator: temperature position regulator, temperature proportional regulator. Humidity regulator: humidity position regulator. Defrosting controller: defrosting temperature switch, defrosting time relay and various temperature switches. Cooling water control: water cut-off relay, water regulating valve, water pump, etc. Alarm control: over-temperature alarm, over-humidity alarm, under-voltage alarm, fire alarm, smoke alarm, etc. Other controls: indoor fan speed controller, outdoor fan speed controller, etc.

Question 9: What industries do thermal energy and power engineering (refrigeration and air conditioning) belong to, and the employment direction is relatively wide, not only household appliances, shipbuilding, power plants and so on. Where cooling is needed in the production process, refrigeration is needed more or less. The heat energy specialty itself is widely employed, and refrigeration is also good as one of the directions. But it depends on what school you graduated from. This is very important.

Question 10: Gree's main business 1985, Zhuhai decided to develop Beiling Industrial Zone with the company as the main body, and Zhuhai Special Economic Zone Industrial Development Corporation, the predecessor of Zhuhai Gree Group Company, was born. Its mission is to develop industries in the special zone and strengthen Zhuhai's economic strength. Developing an industrial zone on a wasteland has led to the rise of real estate projects; Under the unique environment of the special zone, the trade industry has also developed due to the wide application of trade promotion. Since then, the industrial pattern of "one body and two wings" of industry, real estate and commerce has taken root in the soil of Gree Group. After 20 years of cultivation and optimization, the Group has an annual output of 0/50,000 air conditioners, 8 million small household appliances, 0/50,000 quartz watches, 0/20,000 tons of special enameled wires, 0/50,000 electronic components and 20 million printer cartridges. Among them, Gree air conditioners have been ranked first in the same industry in China with the continuous output and sales volume of 1 1. Gree electric fans, heaters, rice cookers, water dispensers, induction cookers, printer cartridges, special enameled wires and other products also occupy an important position in the same industry in China. The real estate industry presents a strong development momentum. In 2004, * * * solved the debt problem that puzzled the group for many years in one fell swoop by means of land compensation, and the original burden and burden became valuable development resources. The real estate industry will adopt the development strategy of "creating fine products, scale and branding" to enhance the value of Gree brand in the real estate field, enhance the development vitality of the Group, and at the same time revitalize the deposited assets to provide financial support for the development of other industries of the Group. In 2004, Xinxiangzhou Mongkok commercial real estate, Gongbei Yiqingyuan commercial and residential building and Gongbei Yufeng Meizhu residential area introduced brand-new business philosophy and marketing management mode, which aroused enthusiastic response from the market, gained wide recognition from the industry, business circles and consumers, and shaped a new image of gree real estate. Among Gree's three major businesses, the petrochemical industry is the youngest. In addition to the traditional fuel oil import business, the trade of other products is gradually expanding. In August, 2004, China Sinochem Corporation and Gree Petrochemical Project formally reached a cooperation to jointly invest in Zhuhai Gaolan Island, build the largest petrochemical storage and logistics base in South China, and build a modern petrochemical logistics platform. It is planned to build two 80,000-ton berths, four 5,000-ton berths and a storage capacity of 2.5 million cubic meters in two phases. It is estimated that after the completion of all projects, the annual comprehensive throughput of the whole terminal will be18.6 million tons. In order to improve the core competitiveness of petrochemical industry, Gree is expanding its business scope and industrial chain in a planned and step-by-step manner, especially taking the port warehousing and dock project construction in Lingang Industrial Zone as an opportunity to develop oil transportation, procurement, import, storage and transportation, sales and other businesses, expand the markets of related products such as chemicals, refined oil and coal, and enter downstream industries such as oil deep processing when conditions are ripe.
