Chapter 1: Overview of professional and technical work with intermediate titles in HVAC major.

I graduated from xxxxX high school on xx, XX, XX, XX, and went to xxxxxxxXXXX photoelectric instrument school to study radio and electromechanical home appliance maintenance technology. Since then, he has been engaged in home appliance repair business. In recent years, with the vigorous development of the real estate industry, I also began to engage in the installation of water and electricity in the construction industry, and at the same time applied for the electromechanical technology work of the construction company.

Ideologically, we should love the motherland, love the people, support the Communist Party of China (CPC), conscientiously study and implement the Party's line, principles and policies, and be consistent with the Party ideologically, politically and practically under the guidance of the 15th and 16th Party Congresses and the Theory of Three Represents Thought. At work, I unite and care for my colleagues and help them enthusiastically. At work, I obey the organizational arrangements, study hard, work hard, study hard, love my job, and constantly strengthen the study of professional knowledge, so that my professional knowledge has been continuously improved and won the affirmation and praise of leaders and colleagues.

Over the years, I have mainly done the following work:

From xxxx to xxxx, I mainly engaged in home appliance maintenance, water and electricity installation, air conditioning and heating installation and maintenance. During my electromechanical technical work in xxxxxx Construction Co., Ltd., I was responsible for the management of electricity, equipment and testing. In the aspect of electrical management, in cooperation with the company's product development, the electrical control system of dumper, the control system of man-vehicle in inclined shaft and the control system of belt conveyor are designed. After being used by customers, the effect is good and the market competitiveness of the company's products is improved. At the same time, he is responsible for the technical transformation of the company's power supply system, planning the company's power supply line to meet the company's expanding production power supply demand, and designing the company's electrical system in the foundry workshop, the new riveting and welding workshop, the support workshop and the idler factory.

Unify and optimize the company's power supply system, meet the production needs, and provide technical support for the company to continuously expand its production capacity. Design the reactive power compensation circuit of the company's power supply, reduce the line loss, greatly save electricity, play a good energy-saving and consumption-reducing effect, and achieve good economic benefits. In terms of equipment management, we actively introduce new electrical control technology and transform the company's old electrical control system. In recent years, I have actively participated in the design, debugging, installation and operation of electrical systems. In the process of installation and debugging, I found the shortcomings in the original design in time. In the installation process, I strictly demand standardization, put forward rectification requirements for irregular line layout, actively participate in the performance test of the main motor, strictly detect the temperature and vibration of the motor, and strictly accept the deviation switch and emergency stop switch along the way to ensure the installation quality of the belt conveyor. In the work, optimize the power supply system, find the hidden trouble of power supply in time, and be responsible for the electrical maintenance of equipment. In the maintenance work, measures were taken to solve many technical problems, which laid a good foundation for the safe long-term operation and normal production of electrical equipment.

Therefore, while doing my job at ordinary times, I actively learn advanced PLC programming technology, understand the development of electrical technology, constantly learn new electrical technology, understand new electrical equipment materials and apply them to my daily work. As engineers and technicians, they must be proficient in computer office software, and can skillfully use Office, AUTOCAD drawing and other software through self-study. I know that only by continuous learning can we keep up with the requirements of the times for the professional quality of engineering and technical personnel, and only by learning and summarizing can we continuously improve our professional level, play a role and make contributions to the development and growth of enterprises.

In short, in my work, I am strict with myself by the standards and norms of an engineering technician, and do every job well with a serious and rigorous attitude and style. Make due contributions to the development and growth of enterprises.

Chapter III: Summary of Professional and Technical Work

I graduated from * * University in July 2000, majoring in HVAC engineering. I am mainly engaged in the construction management and technical work of central air conditioning engineering, ventilation engineering, purification air conditioning engineering, water supply and drainage and electrical installation engineering projects. Through seven years' work practice and study of corresponding majors, I have mastered the basic knowledge and professional knowledge of heating and ventilation engineering and electrical engineering installation engineering, and have considerable professional knowledge and practical experience in the installation and debugging of electromechanical systems.

The following is a summary of my years of major electromechanical installation work in HVAC, water supply and drainage, and electricity:

He has participated in the construction of central air-conditioning projects such as Chongqing Wanzhou Immigrant Hotel, Chengdu Dacheng Market, Science and Technology Archives Building of Chengkan Institute, Leshan Emei Hotel and Zhongjiang Kaiyuan Plaza. In August 2000, I worked in Chengdu Yang Bing Refrigeration and Air Conditioning Engineering Company. My first project is Chongqing Wanzhou Immigrant Hotel. The project was completed in 2000 and located in Wanzhou, Chongqing. It was the most upscale hotel at that time, with four floors underground and fourteen floors above ground, with a construction area of more than 2.8 square meters. This project is the first project I participated in after I joined the work. This project includes building electrical installation engineering, building water supply and drainage engineering, fire alarm, total fire extinguishing, self-extinguishing, central air conditioning engineering and building intelligent system, and is a comprehensive construction project. During the construction of this project, I first came into contact with all kinds of materials and equipment of construction and installation engineering. For me who just joined the work at that time, I just entered a completely strange field. In this project, my daughter learned the construction technology, enriched her technical foundation, and gradually learned some site experience.

Inspection, such as transportation, hoisting, positioning and debugging of various equipment; Site layout of various pipelines and pipelines; Coordination of various professional types of work; Cooperate with decoration specialty. At the same time, I also participated in the actual operation, which made me have more and better understanding of construction technology and technology, and laid a good foundation for independent work in the future. In this project, I also participated in the design of central air conditioning project. Under the guidance of design, how to calculate the load; Design of ventilation duct; Selection of fan coil unit, new fan, main engine and cooling equipment. From previous book knowledge to practical knowledge. In this project, it is also responsible for the acceptance, concealment, technical data collection and reporting of various projects.

Through working practice in Chengdu Yang Bing Refrigeration and Air Conditioning Installation Company, I have a deep impression and understanding of the installation of central air conditioning electromechanical equipment by combining the theory and practice I learned in school, and have initially mastered the design and budget of central air conditioning engineering, the technical management of electromechanical installation engineering and the coordination of various types of work. My enthusiasm and creative value have been affirmed by the company.

On June 5438+ 10, 2002, I came to Chengdu Gaoxin Weichuang Air Conditioning Engineering Co., Ltd. to participate in the construction of Chengdu Dacheng Market Project and served as the technical director of central air conditioning engineering installation. This project adopts French seat ice storage central air conditioning, which is much more complicated than general air conditioning. I am very happy to participate in this project. Central air-conditioning project is more energy-saving than general air-conditioning. Its characteristics are: there are many ice storage tanks to store cold energy at night when there are few people, and release it at noon the next day when people are concentrated; So as to achieve the purposes of reducing energy loss and saving electricity; However, the initial investment of the system is much higher than that of the general central air conditioning project. Due to the whole installation space, the installation area is very large. For the particularity of indoor pipe network, I suggest increasing the slope of pipe network and setting drainage valve at the lowest point of pipe network, which is more conducive to drainage; Increase the expansion joint of the pipeline, improve the ductility of the pipe network and prolong the service life of the pipeline. I also suggest reducing the use of the electromagnetic two-way valve for fan coil units, because the market is open, and the terminal of the central air conditioner does not need to be started frequently. The electromagnetic two-way valve is a precision instrument, which is easy to be damaged when it is started frequently. Water leakage will affect the normal operation of the system and cause unnecessary waste to Party A..

Because the project is a comprehensive project, I also learned a lot of knowledge and experience in the specific construction process. For example, the assembly line method commonly used in group building engineering, because civil engineering is a large assembly line, requires the reserved and embedded work of installation engineering to cooperate with civil engineering faster and better, which inevitably involves the planning and deployment of construction personnel; Plan, organize and distribute on-site materials; Respond to changes in site construction conditions and other related treatment methods. During the whole construction process, I tried to finish my work consciously. However, there are still some shortcomings, such as the coordination between various types of work, the grasp of equipment entry time, etc., which need to be improved. Generally speaking, I am a qualified technician.

The above engineering practice experience provides a practical basis for me to further improve the management of installation projects in the future. I think I will continue to study hard in the future installation work. With the continuous enrichment of experience and the continuous strengthening of technical force, I will become an excellent engineering technical director and an excellent HVAC engineer.

Chapter IV: Summary of HVAC professional work.

I graduated from Hebei University of Engineering, Hebei Province on June 20 10, majoring in building environment and equipment engineering (formerly known as heating, gas supply, ventilation and air conditioning engineering). Time flies, and a year has passed in an instant. This year is very rich for me, and I have changed from a graduate to a qualified engineer and technician in this year.

I officially joined Shijiazhuang Tianyuan Heating and Cooling Technology Development Co., Ltd. on July 20 10, and was engaged in the budget, design and site construction tracking of HVAC. As a fresh graduate, I have expectations and anxiety in the face of a brand-new social environment and a completely unfamiliar working environment. Being able to design HVAC has always been my expectation at school. How to adapt to the new environment as soon as possible and realize the change of work role is the primary problem I face. After entering the company, through pre-job training, the care and help of company leaders and colleagues, the study and self-adjustment of HVAC professional knowledge, and the change of professional role, I quickly adapted to the new environment. Understand the company culture, be familiar with the work function, enter the work state smoothly, and complete the role change from students to professionals.

With the patient guidance of professional masters and old engineers and the enthusiastic help of colleagues, my professional theoretical level and ability to analyze and think problems have been significantly improved, and I have accumulated some practical design experience. We have benefited a lot from integrating the theoretical knowledge we learned before into the actual design. After practical design work and thinking and summarizing various technical problems, I grew up to be an engineering designer with certain design ability and construction site handling ability, and basically mastered the research ideas and analysis methods of professional technical problems, which can better summarize various technical problems. During my work, I kept learning and accumulating, and my professional knowledge gradually improved. During this year, I cooperated with my colleagues to complete the design of many projects.

In terms of design: through the ventilation and air conditioning design practice of these projects and the follow-up management of these projects, the actual problems on the spot have been solved, which has enabled me to have a deeper understanding and understanding of the design requirements, specifications and standards of this major, and clearly felt the importance of design, especially deepened my cognition and application ability of HVAC professional knowledge.

In terms of budget, it is difficult to grasp the spirit of quota in practical work. For example, for a project, all materials are charged, and according to the standard of cost quota, the bid is reduced by 4.2%. Judging from the current situation, the project cost is indeed a bit high. For the quotation of bill of quantities at this stage, winning the bid at a reasonable low price can truly reflect the integration of engineering quotation with the market.

Mainly responsible for the design and construction projects are as follows:

1. Qinghe Xinyu Building

2. Air conditioning terminal project of Baoding Petroleum Company office building

3. Jinzhou Commercial Building.

4. Ventilation and air conditioning of Shijiazhuang Hengda Yujing Peninsula Comprehensive Building

Through working practice, I have made some progress and now I am in a rapidly changing society. I should always learn new knowledge and new culture, study professional technology assiduously, constantly update my professional knowledge, have new ideas, new ways and new measures, have a correct Scientific Outlook on Development, and closely combine with professional knowledge to shape myself into a professional.
