Shi Rui said: "It's close here. The ultrasonic wave detection speed has slowed down."
Deng Fei said: "It's just that the speed was detected to be slow. Why did you rush over nervously to check. Maybe the speed is slow, maybe the sensor is broken."
Shi Rui said: "It's not like the speed is slow, the heat transfer has not changed. If the sensor is broken, the sensor needs to be replaced."
Deng Fei said: "It's really strange. The speed of the detected things has slowed down. Is there something inside?"
Shi Rui said: "I'm weird too. Don't be scary."
Deng Fei said: "What should I do? Take it apart and take a look?"
Shi Rui said: "Okay."
Deng Fei said: "Close the valve. Disassemble the pipe."
Shi Rui said: "What does it smell like? It smells fishy."
After disassembling the pipe, the water poured out something resembling aquatic plants.
Shi Rui called Qin He and said, "The pipes were dismantled here and I saw some waterweed-like things. I don't know what they are."
Qin He said, "Xia Yueling and I also went over to take a look."
Qin He and Xia Yueling came to the computer room. Xia Yueling measured the flow of water in and out of the chilled water pipe network.
Qin He said: "The water leakage has been quite serious recently."
Shi Rui said: "How did you know there was a water leak?"
Qin He said: "The simplest method is that if the flow rate of the inlet pipe is large and the flow rate of the outlet pipe is small, there must be a leak in the middle."
Shi Rui said: "What's the reason?"
Qin He said: "It may be that the connection part of the water pipe fell off and popped out. The middle section was corroded and cracked by freezing."
It may be that the water pipes are aging and loose or bent into a wavy shape, causing poor drainage and easily causing dripping. The water pipe is artificially blocked or the drain outlet is blocked by dirt, resulting in obstruction that cannot be drained.
The air is moist. When using a central air conditioner in the hot summer, if the indoor humidity is high, especially the humidity at the air outlet of the central air conditioner, moisture will be generated in the early stages of startup, and the collected water vapor will condense into water droplets.
The air conditioner has lacked cleaning and maintenance for a long time. When the drain pipe is heavily fouled and heat and cold exchange cannot be achieved, water may leak in the air-conditioning room. At this time, you must first open the filter and remove foreign matter, then check the drain pipe, pour water or blow air to clear it, so as to clear the leakage of the air conditioner indoor unit.
Internal machine placement is offset. When installing a central air conditioner, if the position of the indoor unit placed in the ceiling is shifted, the drainage pipe is not draining smoothly, and water accumulates in the condensate water pan, water leakage from the central air conditioner will occur.
The air conditioner is deficient in fluorine. The inside may freeze. After the ice melts, the ice water will not be discharged too much, causing the indoor unit of the air conditioner to leak. In this case, the air conditioner needs to be added with fluoride.
"It's quite humid down here. Over time, the water vapor condenses into water droplets."
Shi Rui said: "You need to pay attention. One time the air conditioner refrigerant leaked. It was detected that there was a lot of electricity, but the cooling effect was very poor. It was later discovered that the refrigerant was leaking all over the floor."
Deng Fei said: "Then you have to go down and have a look."
Shi Rui said: "Let's go, between entering the water and exiting the water, it must be in the middle section."
Walk along the passage for a while, and according to the sonic detector, it is shown below here.
Several people went down the ladder. Saw a few little mice drinking water next to the sewer.
"Come and pry open this lid. You are strong." Xia Yueling said to Deng Fei.
Deng Fei said: "What are you doing here?"
Xia Yueling said: "Come and detect the target. My mission is completed."
Deng Fei said: "This cover is actually not heavy."
Xia Yueling said: "Can't you show off more?"
Deng Fei said: "Okay, it's okay. This is very easy. Just hold the hook and answer the question."
Deng Fei put the hook into the round hole and lifted it up, but it didn't move.
"what happened."
Deng Fei used another force and managed to open a small crack.
Deng Fei said strangely: "What's inside? Why is it stuck?"
Shi Rui looked through the gap, turned on his flashlight and said, "The pipe below is deformed and the cover is stuck."
Deng Fei said: "Okay."
Shi Rui said: "This cover is very thick, thicker than the original one."
Deng Fei and Shi Rui worked hard together. Shi Rui moved from below and finally pulled out the cover. Shi Rui shined a flashlight downwards, but there was nothing there.
Shi Rui said: "Let's go down and take a look now?"
Xia Yueling said: "Go and have a look."
Shi Rui said: "Let's go down first. You don't have to go."
Xia Yueling said: "It doesn't matter. Let's go down and have a look."
Everyone go down the ladder.
The sound of a saw was heard in the distance.
Deng Fei said, "Did you hear the sound of sawing? Are things being repaired down there?"
I shined a flashlight, but still nothing. The group of people arrived at the corner. Qin He saw some hair on the ground.
Shi Rui said: "What is this? What kind of animal hair is it?"
Deng Fei said: "It's from a rat."
Xia Yueling said: "There are still some here."
Qin He said: "Keep moving forward and take a look."
Water began to leak downwards in many places, like rain. The water was not big, but my clothes got wet.
Xia Yueling said: "It's really annoying. I didn't bring an umbrella. It's raining here. There's no way to protect myself from the rain."
Where the sound comes from. He took a flashlight to shine again.
It turned out to be a huge rat-like animal. The teeth are very long, and they are used to cut water pipes like a saw. The tail has a relatively large round ball.
"I'll take photos and search to see what kind of animal it is," Shi Rui said.
"Saw-toothed mole. Lives underground and likes to eat earthworms, mud flies, etc. It is good at drilling holes and sawing through hard wood and even metal."
Xia Yueling said: "What's the tail behind this?"
Deng Fei said: "It can wrap things and is easy to carry. It is equivalent to having an extra hand."
The saw-toothed mole heard the sound, turned towards them, and rushed over.
Several people stepped aside. Deng Fei stood closest, unable to dodge, and touched its tail. The tail opened and the water inside spilled to the ground. The Saw-toothed Mole rushed to a hole next to the wall and got in.
Xia Yueling said: "What is the water behind the tail doing? Is it used to store water?"
Qin He said, "Look what's in the water on the ground."
It turns out that there is not only water on the ground, but also some aquatic plants.
The fibrous roots are well developed, brown and black. The stems are very short and the stolons are light green. The leaves are clustered at the base and arranged in a rosette shape; the leaves are round with dark green surfaces; the petioles vary in length, with vascular bundles scattered between them, ranging from yellow-green to green; there are sheath-like yellow-green bracts at the base of the petiole; the scape is multi-ridged; the spike-like inflorescence ; The petals are purple-blue, the corolla is symmetrical on both sides, lavender around, blue in the middle, and there is a yellow round spot in the blue center.
Qin He said: "The phoenix eyes are blue."
Deng Fei said: "Mr. Qin, you know this. Are you studying biology?"
Qin He said: "I swam in the nearby lake and saw it. But if there were too many, it would block the river water, so the administrator controlled its growth circle."
