The following is a summary and reflection on the knowledge training of high-efficiency refrigerator room: * * 1. Knowledge summary ** 1. * * System composition and principles ** - The refrigerator room could be divided into five parts: the refrigerator unit, the cooling water pump group, the chilled water pump group, the water splitter, and the cooling tower, as well as two cycles. One cycle was that the refrigerator room supplied cooling water to the outdoor cooling tower through the cooler of the refrigerator unit, and the cooling tower cooled down and then supplied it back to the cooler; the other cycle was that the boiler of the refrigerator unit supplied chilled water to the water splitter, and the water splitter sent the chilled water to the end of each air conditioner, collected by the water collector, and sent back to the boiler through the freezing pump. - The basic components of the cooling cycle were the chiller, the boiler, the air conditioner, the throttle device, and so on. - The system capacity of the refrigerator room requires the number of chillers to be planned according to the actual demand. For example, a refrigerator room is planned to have 11 chillers (9x1000 (rt)+2x500 (rt)), and five chillers (3x1000 (rt)+2x500 (rt)) are planned to be installed in this period. They also have heat recovery functions. The rt (cold ton) here has a specific cooling capacity conversion relationship (1 cold ton in the United States = 3024 kcal/h = 3.517KW). 2. * * In terms of installation and layout ** - When the pipes in the machine room were large and dense, the main pipes should be arranged in a row and branch upward as much as possible, which would be helpful for aesthetic appearance and later support construction. - During space control, the pipe connection was mostly done by welding. The thermal insulation space and the space for welding operation (including the distance between the vertical pipe and the wall) should be considered. In addition to the conventional maintenance space, the maintenance and tube-pulling space of the refrigerator unit should be reserved according to the type of equipment. - In terms of details, the pipe connection could be connected in the direction of water flow. The pipe accessories and valve were installed at a unified height. The variable diameter of the water intake pump and the cooling unit was connected with eccentric top joints. The vertical pipe connected to the equipment was supported by the support arm, and the connecting pipe of the unit on the same side as the four ports should be staggered. 3. * * In terms of ventilation design ** - In terms of the system form, the ground refrigerator room should adopt natural ventilation. If it is not enough, the underground refrigerator room should be equipped with a mechanical ventilation system, which should be set independently. There should be a normal ventilation system and an emergency ventilation system (the normal ventilation system of the underground refrigerator room can also be used as an emergency ventilation system). - The air volume is determined by the air exchange rate method. The air intake and exhaust fan can choose the dual-speed fan. If it is difficult to choose a suitable model for the dual-speed fan, the system can be set to two fans in parallel (one in normal operation and in parallel operation during emergency ventilation). At the same time, pay attention to the position of the air outlet to avoid air short-circuit caused by the air intake and exhaust outlets being too close. 4. * * Special circumstances of air conditioner installation ** - When installing an air conditioner in the weak electricity room of a high-rise office building, if there was a problem with the placement of the external unit (for example, the high-rise outer wall was full of glass curtain walls and could not be externally installed, it could only be placed on the roof and the copper pipe was too long), it would affect the cooling effect of the air conditioner and even the life of the machine. For example, Gree's household air conditioner copper pipe was more than 20 meters long, and the cooling effect was greatly reduced and might burn the compactor. Midea, Dajin, and other manufacturers did not dare to sell it. Even if they used measures such as installing a pressure relief bay in front of the air conditioner's copper pipe, the cooling effect would still be affected. * * 2. Reflection ** 1. * * Depth of Knowledge Understanding ** - For the various links in the system principle of the refrigerator room, such as the working principle of the chiller, the boiler, the turbine, and the throttle device in the cooling cycle, it may require further in-depth research. Although he understood the overall cycle process, it was not clear how to accurately adjust the parameters of each device according to different cooling needs in practical applications. 2. * * Real-world considerations ** - In terms of installation layout, although he knew the principles of pipeline arrangement, space control, and details, he might encounter various complex building structures and space constraints in actual projects. How to flexibly apply these principles required more practical experience. For example, when encountering an irregular computer room space, how to adjust the pipeline layout to meet the functional requirements while ensuring safety and aesthetics was a challenge. - In the ventilation design, the specific calculation method of the air volume determined by the air change rate method and the optimal ventilation rate setting of different types of refrigerator rooms (according to the size, use, etc.) needed to be further explored to ensure the efficiency of the ventilation system. 3. * * Ability to deal with special situations ** - From the case of air conditioner installation in the weak current computer room of a high-rise office building, there was a lack of adequate solutions in the face of special installation environments and customer needs. He needed to accumulate more experience in dealing with similar special situations, such as how to assess the risks in advance and provide more reasonable solutions when encountering problems such as difficulties in placing external machines and excessive length of copper pipes, rather than trying various less ideal remedy measures after the problem occurred. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

In-service teachers applying for a disability certificate (disability assessment) had no negative impact on their work. On the contrary, it had a positive side. In terms of job stability, a teacher with a disability certificate could not be terminated at will in the school. The school would try its best to arrange a suitable position for him. For teachers without a disability certificate, the school could terminate the contract without paying a certain price. From the perspective of social welfare benefits, teachers could enjoy tax concessions and reduce fees. For example, the services provided by disabled individuals were exempted from business tax, and their income could be temporarily exempted from personal income tax upon application and approval. However, physical disability may cause some obstacles in actual teaching work and affect teachers 'performance. For example, although high nearsightedness can apply for a disability certificate, it will affect vision and thus affect homework marking, writing on the blackboard, and so on. Hearing loss will affect communication with students. Therefore, in general, the assessment of teachers 'disability had a positive impact on the stability of work contracts and welfare benefits, but physical disability may cause certain obstacles in the practical operation of teaching work. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Song of Everlasting Regret was a long narrative poem written by Bai Juyi, a poet of the Tang Dynasty. The opening of the poem described the extreme love Emperor Xuanzong of the Tang Dynasty had for Yang Guifei, such as "The Emperor of Han was so fond of women that he wanted to destroy the country. The Yang family had a daughter who had just grown up and was raised in a boudoir. No one knew her. A natural beauty is hard to give up, and once she is chosen to be beside the king. Looking back at her, she smiled and became a hundred times more charming, and the six palaces were colorless. These sentences vividly displayed the beauty of Yang Guifei and the special favor she received after entering the palace. After that, the An Lushan Rebellion broke out, breaking the peace and prosperity. At Mawei Slope, Yang Guifei was forced to commit suicide. The latter half of the poem was mostly about Emperor Xuanzong's longing for Yang Guifei. For example,"The moon in the palace is sad, and the bell in the night rain is heartbroken." He asked the Taoist priest to search for Yang Guifei's soul."Empty the air and control the qi to run like lightning, ascend to the sky and enter the earth to seek everywhere." In the end, he found Yang Guifei on the celestial mountain on the sea. She appeared in the image of "lonely tears, pear blossoms in spring rain". The two expressed their longing for each other and made a vow of "in heaven, I wish to be a pair of lovebirds, in earth, I wish to be a pair of connected branches." The heavens and earth will last forever, and this hatred will last forever. In addition, there were also musical works, dance dramas, etc. named after "Song of Everlasting Sorrow." These artistic forms were all based on Bai Juyi's poem and interpreted the story of "Song of Everlasting Sorrow" from different angles. The novel "Song of Everlasting Sorrow: Morning and Evening" is equally exciting. Everyone is welcome to click and read it!

The panic reaction would cause breathing to become irregular. A panic attack was an intense, sudden, and unpredictable anxiety disorder that was usually accompanied by strong physical symptoms, including breathing difficulties. Physiologically speaking, when most people had a panic attack, they would involuntarily increase their breathing rate due to nervousness, leading to hyperventilation and reducing the carbon dioxide content in their blood. When carbon dioxide dissolved in the blood, it was carbolic acid, which was acidic. When the content decreased, it would increase the blood's alkalinity, leading to respiratory finement, which would cause numbness in the lips and limbs, tingling, and other symptoms. It would aggravate the state of panic, which would affect the smoothness of breathing and form a vicious cycle. From a psychological point of view, when a panic attack occurs, the central limbic system of the brain is affected, which may cause the metabolism of 5 -ht to be disordered, resulting in a decrease in the release of neurotransmitter such as Dopamine, norepinephrin, and acetoxine, resulting in symptoms of anxiety and depression. This kind of anxiety will trigger the body's stress response, leading to physiological phenomena such as uneven breathing. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

In the context of finding a job, the establishment referred to the establishment of an organization, the quota of its personnel, and the distribution of duties. The amount allocated by the financial department was determined by the establishment department at all levels, and the financial department allocated funds accordingly. The establishment was usually divided into administrative establishment, enterprise establishment, labor establishment (in a broad sense, labor establishment was a type of enterprise establishment), personnel establishment, and state-owned enterprise establishment (bank establishment was a type of state-owned enterprise establishment. The state-owned enterprise establishment was not guaranteed by financial allocation, but was borne by the enterprise itself). The administrative establishment mainly involved civil servants. They were the official employees of the administrative organs and were responsible for the management of the various levels of the state's administrative organs. They were managed by the Organization Department and paid by the state. They were assessed and selected according to the Civil Servant Law. They were promoted to their positions and ranks. They mainly worked in state organs, the organs of the Party, the organs of the democratic parties, the organs of the People's Congress, the organs of the Chinese People's Political Conference, the courts, and so on. Their purpose was to serve the masses. The official staff of the institution were divided into management posts and technical posts. They were generally managed by the Human Resources and Social Security Bureau, and the deputy section chief and above were managed by the Organization Department. The salary was generally paid by the unit or half paid by the state and half paid by the unit. The promotion was generally divided into five categories, namely, general management, social science, natural science, primary and secondary school teachers, doctors, pharmacists, nurses, and so on. In a broad sense, the work force establishment was a business establishment. The establishment of state-owned enterprises was borne by the enterprises themselves, and the establishment of posts was also a type of establishment. When looking for a job, different types of personnel meant different job nature, management methods, salary sources, and promotion paths. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following is the content of the lecture notes of two fourth-grade primary school students: ** First and Fourth Mixed Arithmetic (PEP Experimental Version, Grade 4, Volume 2)** 1. ** Talk about teaching materials ** - The content of the lecture was the first unit,"Four Mixed Operations," example 4 (the mixed operation of the sum (difference) of two quotient (product)). This content was taught on the basis of the students learning the addition and reduction hybrid operation, the multiplication and division hybrid operation, and the hybrid operation of the sum (difference) of the product quotient. It was the foundation for further learning the four hybrid operations. - Teaching objectives: - In the process of solving practical problems, let the students feel that using parenthesis is a strategy to solve practical problems. - To enable students to grasp the order of operations with two levels of operations (with small parenthesis) and to calculate correctly. - Through thinking and independent inquiry, students were allowed to take the initiative to participate in teaching activities, cultivating their main consciousness, problem awareness, exploration spirit, cooperative communication awareness, as well as the habit of thinking independently and considering problems from different angles. - Teaching key points and difficulties: Seeking scientific and reasonable methods to solve problems is the key point of teaching. The difficulty of this lesson is to master the order of mixed operations with small parenthesis. 2. ** Teaching Concept ** - A teacher's teaching plan should be based on the students 'foundation. It should start from the students' thinking and stimulate the desire to explore knowledge. This was because different students had different cognitive levels, cognitive styles, and development trends. ** 2. Adding and Subtracting Decimals (Primary School Mathematics Version, Grade 4, Volume 2, Unit 6)** 1. ** Teaching Material Analysis ** - This teaching content was arranged on the basis that the students had mastered the meaning and nature of decimals and the addition and substitution of whole numbers. It was the need of students 'daily life and further study. Compared with the old textbooks, the textbooks chose materials that the students were familiar with and interested in as the background of the calculation teaching, so that the calculation teaching was no longer boring. The mathematical theory of decimals addition and decimals was similar to that of whole numbers. The textbook guided the students to transfer the old knowledge of whole numbers addition and decimals to the new knowledge of decimals addition and decimals. 2. ** Analysis of teaching and learning methods ** - Closely connect with life and create problem situations. For example, with the help of the material "cloned cow" to stimulate students 'curiosity, the introduction of decimals addition and substitution teaching, in the consolidation section set up such as "I compare height with Yao Ming" and other problem situations, reflecting the concept of mathematics coming from life and serving life. - The teacher was bold and let go, and the students explored on their own. Since the students had the foundation of integral addition and deduction, the students were allowed to collect information, raise and solve problems by themselves. The teacher did not prompt them and let the students try to write decimals in the vertical form. They would understand the calculation method during the exploration, and then summarize the general method of pen calculation through communication to understand the principle of decimal point alignment. - The students 'ability to discover problems and raise questions was emphasized. For example, the cloned cow situation was used to let students ask math questions and explore the calculation method of decimal addition and multiplication. 3. ** Teaching goal ** - Understand the meaning of decimals addition and deduction based on the specific situation. - To master the calculation method of decimals addition and deduction, to be able to do pen calculations more skillfully, to cultivate students 'good calculation habits, and to improve their calculation ability. - Let the students feel the joy of learning mathematics, enhance their confidence and sense of success in learning mathematics, and form a good habit of transferring and analogy. - The teaching focus was on the method of decimals addition and deduction and the process of exploration. The difficulty of teaching was the truth of decimals alignment (digit alignment). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
