Qin He was born into a family of skilled workers. Excellent academic performance, participate in more sports activities, and perform well. After working, he held some management positions. Later he served as technical manager.
Relatively positive energy, cheerful and helpful.
Like swimming, fitness, boxing, sports.
Met this at a previous company.
To this day, she still doesn't quite understand why a few people made things difficult for her at that time. She had to stop her from doing the Qimaishan project. Let’s talk about everything and let’s play fair.
"She was not familiar with the area, and the round trip was long and slow."
"Can't I find a driver? There is a navigation."
"The navigation doesn't show that location either."
"Is this all the reason why I can't do it? These are small things that can be overcome."
"You don't have enough experience yet, so it's not suitable for you to do such a big project now."
"Why doesn't it fit? Look at the project description, it's similar to the buildings in the city."
"You can't just read the project description. Do you know what the situation is like on site?"
"I never said that you have to see it live before you can do it. I can just go over and take a look."
"This place is close to tourist attractions. Whether it can be completed will have a big impact."
It's hard for Qin He to say anything else. Maybe this project is more important. It doesn't matter if you wait for other opportunities first.
But she said she should go and study, but she was not even allowed to go.
This time I went to the mountains to take a look, and I realized that what they said did make sense. There may be some strange things drilled out there due to the movement of the earth's crust. Includes some new plants, stones. I don't know if there are any other dangerous things.
I am very satisfied with the job I have found now. Professional counterpart, engaged in HVAC design. The staff relations are also good and colleagues get along well with each other. There are no difficulties like the original company. The younger ones treat her like a big sister. The older ones are also kind-hearted.
The HVAC major has such research directions. Air conditioning system design and optimization: including research on air conditioning system design, energy-saving measures, environmental adaptability, etc. Heating system design and optimization: including research on heating system design, gas supply, water circulation, pipeline layout, etc. Indoor air quality control: including research on indoor air pollutant control, indoor air circulation and fresh air systems. Energy efficiency research: including research on energy-saving equipment, energy management and control, etc. Green building design: including research on indoor and outdoor green design, building energy efficiency and sustainability. Thermodynamics and fluid mechanics research: including research on flow heat transfer, phase change heat transfer, microscale heat transfer, etc. Research on building energy-saving technologies: including research on building insulation, solar energy utilization, biomass combustion, ground source heat pumps, etc.
Deng Fei prefers air conditioning system design. Shi Rui and Xia Yueling prefer heating system design. Qin is responsible for the study of thermodynamics and fluid mechanics.
When he arrived at the new company, Qin He carefully studied various air conditioning systems.
One time a customer said the air conditioner was broken. She went to the place to check for a long time and found that the exhaust pipe and suction pipe were very hot.
Touch the three lower tubes of the four-way valve with your hands. If they are all hot, it means that the four-way valve is not reversed in place and is in a state of air leakage in the middle.
The customer asked: "Isn't it compressor cross-gas?"
Qin He said to him: "Test the suction and exhaust pressure to judge. If the high and low pressure hysteresis is small; the return pipe of the compressor is very hot, the operating sound is very small, and the current is too small; the temperature on the surface of the compressor is too low." High. This is the compressor cross-gas."
"You can see that the heat exchange effect has obviously deteriorated; the return air pressure has increased and the exhaust pressure has decreased. When the four pipes on the four-way valve are normal: two are high temperature and two are low temperature; after air leakage, there will be three The above high temperature or normal temperature. So now it is a fault of the four-way valve cross-gas."
A four-way valve is a control valve with four oil ports. It is an indispensable component in refrigeration equipment. Its working principle is that when the solenoid valve coil is in a power-off state, the pilot slide valve moves to the left driven by the compression spring on the right side. The high-pressure gas enters the capillary tube and then enters the right end piston chamber. On the other hand, The gas from the piston chamber at the left end is discharged. Due to the pressure difference between the two ends of the piston, the piston and the main slide valve move to the left, so that the exhaust pipe is connected to the outdoor unit pipe, and the other two pipes are connected to form a refrigeration cycle. When the solenoid valve coil is in the energized state, the pilot slide valve overcomes the tension of the compression spring and moves to the right under the action of the magnetic force generated by the solenoid coil. The high-pressure gas enters the capillary tube and then enters the left end piston chamber. On the other hand, the gas in the right end piston chamber is discharged. There is a pressure difference at both ends of the piston, and the piston and main slide valve move to the right, so that the exhaust pipe is connected to the indoor unit pipe, and the other two pipes are connected to form a heating cycle.
Qin He found out that the four-way valve was causing air leakage, and suggested replacing the four-way valve. The air conditioner is running normally after the repair.
For each type of air conditioner, there may be multiple faults. She listed the causes of each fault and then sent them to other employees and customers.
For example, if the cooling effect of water-cooled central air conditioners deteriorates: it may be due to dust or dirt on the surface of the condenser or evaporator, or the waterway is blocked and needs to be cleaned or cleared. Compressor noise becomes louder: It may be due to damage to the compressor bearings or internal leakage of the compressor. Condensate water retention: It may be caused by the condensate water pipe being blocked or bent and needs to be cleaned or unclogged. Condenser leakage: It may be due to leakage in the internal pipes of the condenser or damage to the surface of the condenser, which needs to be replaced or repaired. Circulating water pump failure: It may be due to damage to the circulating water pump or motor failure. The water pump noise becomes louder: it may be caused by damage to the water pump bearings or foreign matter inside the water pump. The water-cooling unit suddenly stops: It may be due to power failure, temperature sensor failure, or blockage in the water circulation system. Control panel failure: It may be due to a control panel circuit board failure or a program problem.
Through continuous learning and practice, she gradually accumulated rich experience and technical knowledge in the air-conditioning industry, and began to gradually assume the role of project leader. Constantly trying new technologies and solutions has saved the company a lot of costs, while improving product quality and customer satisfaction.
Due to her outstanding performance and recognition from her leaders, she was promoted to deputy manager of the technical department. In this new role, I began to lead the team, coordinate the work of various departments, and be responsible for technology development and product research and development, etc., which put forward higher requirements for management and talent capabilities.
The company's board of directors believes that she has solid professional knowledge, has a deep understanding of the technology, market and customer needs of the air-conditioning industry, and continuously improves her professional skills at work. Have problem-solving skills and be able to quickly identify and resolve technical issues to ensure product quality and customer satisfaction. So she was promoted to technical manager.
