2, efficient cooling and heating function: Belight central air conditioning adopts advanced cooling and heating technology, which can provide ideal temperature and humidity control for the entire room in the shortest time. Multiple function Settings: Belette central air conditioning can achieve a variety of function Settings, such as automatic, manual, timing switch, thermometer and hygrometer. Users can choose the right functional mode according to their needs and preferences.
3, screw chiller commissioning (1) refrigerant charging. At present, the refrigeratorThe group is generally charged with refrigerant before leaving the factory as required. After on-site installation, if no accidental damage is found in the appearance inspection, the relevant valve can be opened directly (the operator's instruction manual should be read first, and the valve on the unit is generally in the closed state during transportation).
4, the controller is the core of the whole system, it by writing code to achieve different modes of control, such as refrigeration, heating, dehumidification, air supply. The controller can also detect temperature, humidity, pressure and other data for better adjustment and control. In addition, the code of Belette central air conditioning also includes the control and status of the equipmentDetects.
5, secondly, if the filter or radiator in the air conditioner is not clean, it will also lead to compressor failure, which will affect the refrigeration effect of the air conditioner and increase the maintenance cost. In addition, the compressor may also be due to insufficient or excessive lubricating oil, resulting in friction damage or hinder its normal operation. There are some other reasons, such as electronic component failure, corrosion, etc., will lead to the failure of Belette central air conditioning compressor.
1, accounting computerization is accounting, learning accounting theory knowledge, accounting manual account. Accounting software operation, computer basic software operation. After graduation, I will only issue a diploma, and the certificate of accounting is to be taken by myself. Accounting computerization major is a characteristic major in Shandong Province, which comes from the financial accounting major in the merged schools of five universities, and has a history of more than 30 years.
2. Main courses of accounting Computerization: Basic accounting, management, Economic Law, Tax law, primary accounting practice, cost accounting, accounting computerization, auditing, financial management, tax accounting, enterprise accounting simulation training. accountantThis course systematically introduces the basic theories, methods and procedures of accounting.
3, Basic accounting, Elementary Accounting Computerization, Financial Laws and Regulations and Professional ethics, Advanced Mathematics, Western Economics, Elementary Accounting Practice, Intermediate Accounting Practice, Elementary Economic Law, Intermediate Economic Law, Cost Accounting, Principles of Statistics, Financial Management, Modern enterprise Strategic Management, Strategic Management and risk Control, Marketing, English, Basic Vocational Computer, VFP programming, UFida software, foreign accounting practice, etc.
4, accounting computerization has become a combination of computer science, management science, information departmentScience and accounting science as one of the fringe disciplines, in the various fields of economic management in the application of electronic computers in the leading position, is playing a role in driving the economic management fields to gradually modernize. Accounting computerization greatly reduces the labor intensity of accounting personnel, improves the efficiency and quality of accounting work, and promotes the transformation of accounting functions.
5, Architectural engineering technology: This major is another advantage of Dezhou Vocational College of Science and Technology, the college has a team of experienced teachers and first-class experimental facilities. Students here can learn architectural design, construction management, project budget and other aspectsKnowledge, after graduation can work in construction companies, design institutes, real estate companies and other units. Accounting computerization: With the development of economy, the demand of accounting computerization is also increasing.
National Women's Football Super League will be held in Luohe Sports Center Stadium from April 13 to 29, this event is sponsored by Chinese Football Association, Henan Football Association and Luohe Sports Center, Shuanghui GroupCo-sponsor.
The Chinese Football Association Super League is the top league of the Chinese professional football league organized by the Chinese Football Association, and its predecessor is the National Football Team (Group A) league founded in 1989. In April 2006, in order to further improve the marketization process of the Chinese football industry, the Chinese Football Association and all the participating clubs of the Chinese Super League jointly funded the establishment of the Chinese Super League Limited liability Company.
Schedule of 24th June 24th 17:30 Guangzhou vs Shanghai Port; June 24, 19:30 Wuxi Wugou vs Tianjin Jinmen Hu; June 24th, 19:30Dongguan vs. Shandong Taishan; June 24 19:30 Heilongjiang Ice City vs Nantong Branch Cloud. June 25th Schedule June 25th 16:00 Nantong Haimen Ketiyuan vs Shenzhen team.
The relegation group consists of the bottom four teams in the two divisions. In a double-leg match, the two teams compare the outcome and then the number of goals scored. If the number of goals remains the same, extra time will be played. In the event of a draw after extra time, it will eventually go to a penalty shootout. After the final ranking, the 16th place will be relegated directly, and the 15th place will play a play-off with the second place in the Chinese League to compete for the last place in the Chinese Super League next season.
The schedule of the Chinese Super League is as follows: Shandong Taishan will play Chengdu Chengdu at 19:30 on November 21, and Wuhan Sanzhen at 17:30 on November 26. Guangzhou VS Beijing Guoan will be played at 19:30 on November 21.
1, refrigeration system debugging. After refrigerant is charged (if refrigerant needs to be charged), you can perform load commissioning.
2,. Press the F2 normal stop key on the control cabinet and the unit willFirst unload, stop the compressor after unloading, then electrify the oil heater. When the compressor is stopped, 25% of the energy runs for 30 seconds before stopping; Delay 1 minute to stop the cooling water pump, and delay 2 minutes to stop the freezing water pump. If the emergency stop key on the electric control cabinet is pressed, the unit will immediately stop the compressor regardless of the current load state.
3. Press the "ON/OFF" button to open the chiller system; Press the "SET" button to enter the parameter setting interface. Press the "UP" or "DOWN" button to select the temperature parameter to be set; By "UP" or "DOWN."Button, adjust the temperature parameter value; After the Settings are complete, press SET to save the Settings and exit the menu.
4, you said a part of the right, screw compressor energy regulation is achieved through the adjustment of the effective compression space of the compression chamber, the signal source is the pressure at the low pressure end, can also be understood as the pressure in the evaporator, according to the low pressure to control the solenoid valve of the compression chamber open and close.
5,. (1) Because the screw chiller belongs to the medium and large chiller, it needs to be designed, installed and used in the commissioningClose coordination among the three parties. In order to ensure that the commissioning work is carried out in an orderly manner, it is necessary to form a temporary test group by the relevant personnel to fully command the commissioning work.
6, first connect the power supply, connect the cooling water pipe. Turn on the host power, press the start button to start the screw chiller. Adjust the set temperature and water flow to make the chiller work in the best condition. Check water level and water quality regularly to ensure clean water quality. Observe the pressure and temperature of the chiller to ensure that it is working properly. If any exception is found, shut down the device in time to rectify the fault.
