Shi Rui found that there was a power outage in one place and called an electrician to check the power supply line. Fuses, fuses, voltage regulators, resistors and capacitors. Finally the resistor and capacitor were replaced.
The cooling effect is reduced. I couldn't find the reason for a while.
Look outside the pipe to see if there are any leaks. Are there any abnormal vibrations in the water pumps of several units?
Then check if there are any problems with the compressor, evaporator, and reversing valve inside. Measure the inlet and outlet water temperature, pressure and flow rate of the unit. Is the temperature set too high? Is too low set automatically or manually? Check whether the pressure changes too much or too little, whether there are any blocked connections, blocked pipes, and whether there is any water leakage.
Check whether the flow rate changes, whether there is water leakage, or whether the flow rate corresponding to the set valve opening is correct.
Manager Qin and Shi Rui describe some methods of inspection. Shi Rui and two repairmen, Deng Fei and Xia Yueling, checked one by one.
Deng Fei said: "The water temperature and flow settings are normal. There is no water leakage seen from the outside."
They continued to inspect, and Shi Rui saw a square part inside the pipe, which was a user notification, but why was it posted in this place. Behind the pipe, it is difficult to see and you need to drill through to see. It is usually posted in an obvious place, on the wall, next to the control box. Curious, he crawled under the pipe and found a gap on the side that could be pressed. But it bounces back after pressing it. Don't know what was started.
He continued to walk around, and in another room, he saw a square part behind the pipe, which was a notification of use. There is a gap on the side circle that can be pressed. It bounces back after being pressed.
There is a square part behind the iron frame pipe on the roof, please let me know. There is a gap on the side circle that can be pressed. It bounces back after being pressed.
He continued to search and told the two repairmen that you should also look for such a hidden square button that can be pressed.
I saw a square usage notice behind the power distribution cabinet. There is a gap on the side circle that can be pressed. It bounces back after being pressed.
He began to press the buttons in order, pipe 1, pipe 2, unit, and distribution cabinet. Unit, distribution cabinet, pipe 1, pipe 2.
Shi Rui said: "Look at the changes in the equipment in the room."
Deng Fei said: "No, I heard the sound of the motor turning. Then it disappeared again."
Shi Rui said: "What kind of button is this? It triggers a mechanism. Can it start the machine?"
Deng Fei said: "Is it some secret passage mechanism? Is it a trap? It's sinking, or there's an arrow flying out."
Xia Yueling said: "No, this is a computer room, not a theft-proof area where treasures are placed."
Shi Rui said: "You press the button at the same time."
Deng Fei said: "There are only three of us, and we can press three buttons at the same time."
Shi Rui said: "The other one is held up with a wooden stick to prevent it from bouncing back."
Just like that, the four buttons were pressed. Hearing a creaking sound, he looked around and saw a door opened on the ground.
They walked over to the door. The button bounced back and the door did not close. There is also a ladder under the door.
Going down from the ladder is a passage with thin pipes on the ceiling.
Shi Rui called Qin He and said, "Mr. Qin, we have made a major discovery. There is a secret passage down here and some water pipes. It should be water pipes, judging from the sound."
Qin He said: "What, then who built this? We don't know."
"It was probably done together when the building was built."
Qin He said: "It may also be that underground passages and pipelines were built during subsequent maintenance."
Deng Fei said: "What is this for? Is it a water supply pipe?"
Xia Yueling said: "It looks like it, the diameter of the water supply pipe is also this big."
Deng Fei said: "Then continue to follow this pipeline and see where it is connected."
Shi Rui said: "Maybe it's the water supply pipe. It's not the heating pipe."
Xia Yueling said: "Look along this pipeline. It is towards the direction of the woods."
Deng Fei said: "It may be a connection between the woods and the city."
Shi Rui said: "Is the water coming from the woods, or is the water from the city supplying the woods?"
Maybe things from the woods were transported to the city.
What is the purpose of transporting water from the woods to the city?
Xia Yueling said: "It is possible to provide drinking water to the city. Water sources in the woods can be used to supply the city's drinking water needs. Through water transportation, water is transported from the woods to the city's water treatment plant, and after treatment it can be used for residents' lives. Water. Ecological protection, water transportation from the woods to urban water sources, also helps maintain the ecological balance around the city. These water sources can supply the water needs of ecosystems such as wetlands, rivers, lakes, etc., and maintain the stability of biological diversity."
Deng Fei said: "Or agricultural irrigation, water sources in the woods can be transported to farmland around the city through water transportation for crop irrigation. Minerals are crucial to the growth and development of crops, and can increase crop yields and Quality. Industrial water is supplied to urban industrial enterprises for cooling, cleaning, manufacturing and other needs in the production process."
Shi Rui said: "You are talking about the application of water in industry and agriculture, but now the water is passed into the building."
Water may have such effects in buildings.
Water for drinking and sanitation. The tap water system in the building provides drinking water and sanitary water, including drinking water faucets, toilet flushing water, wash basin water, etc. These water sources ensure people's daily life and health needs.
If there are any problems with the water quality coming from the forest, it will also affect the safety of users in this building.
Fire protection systems in buildings require large amounts of water to supply functions such as fire extinguishing and emergency sprinklers. Fire-fighting water can be used to supply water for fire hydrants, fire extinguishers, sprinklers and other fire-fighting equipment to ensure fire prevention and control inside the building. Water sources in buildings can be used to clean and decontaminate various areas inside and outside the building. For example, it is used for floor cleaning, window cleaning, air conditioning system cleaning, etc. to keep the building clean and hygienic. It can also be used for cooling and heating in air conditioning and heating systems. Through the water cooling system, the temperature and humidity inside the building can be adjusted; while the heating system provides indoor heating services by circulating hot water.
But look at this water pipe and the water pipe of the air conditioning system are not together.
They had to take the elements in the water to a chemical laboratory for analysis.
"It's really strange. There are some elements here that we haven't discovered before."
Shi Rui said: "I don't know what new element it is. Is it harmful to the human body?"
Xia Yueling said: "The preliminary test results are harmful and will affect the activity of the protein."
Shi Rui said: "Then this water pipe is still transporting this water, should it be closed?"
Qin He said: "I will report it to the owner, then close the water pipe, and then you can follow the water pipe to see where it is transported."
