Causes of refrigerant leakage and flooding in the air conditioner of the computer room and the treatment methods!

　　【】The leakage of computer room air conditioner refrigerant is common, and the computer room air conditioner leaks frequently. In fact, there are many reasons for the computer room air conditioner leakage. Existing problems will cause the computer room air conditioner refrigerant leakage and water leakage.

　　 Reason 1: Use problems

　　 In terms of use, one is ‘dirty blockage’, that is, dust that has not been cleaned in time accumulates in the plastic pipe, causing poor drainage. The second is that the drain pipe is moved or knotted. Third, the drain pipe that has been used for a long time is cracked due to aging of the plastic.

　　Cause two: installation problems

　　In terms of installation, when installing an air conditioner that is inclined, that is, the levelness is unqualified, water will leak due to moisture accumulation. The wall hole punched during installation is too high, causing the drain pipe to lead out to a higher position, causing the drain pipe to not drain smoothly, making the water receiving pan of the indoor unit overflowed with water, and the indoor unit will also leak water.

　　About the problem of water leakage in the indoor unit:

　　 Treatment method: The installation drainage angle is not handled properly, and the drainage pipe can not be bent less than or close to 90 degrees, nor can it be bent too much. Use PVC pipe material; the embedded internal unit is not installed horizontally, readjust the level of the indoor unit.

　　About the problem of the air conditioning drain pipe in the computer room:

　　a. The inclination angle of the drain pipe on the indoor unit side (wall-mounted, cabinet type) is too small. Treatment method: readjust the angle of the drain pipe.

　　b. The drain pipe is too long and the water flow is not smooth. Treatment method: Try to shorten the length of the drain pipe.

　　c, the drain pipe is uneven and twisted. Treatment method: rearrange the drain pipe.

　　d, the drain pipe (hose) is squeezed. Treatment method: clean up the squeezed part of the drain pipe (hose).

　　e, the drain pipe is broken or cracked. Treatment method: Replace the drain pipe.

　　f. Insert the water outlet of the drain pipe into the water. Treatment method: Take out the drain pipe inserted into the water.

　　g, the drain pipe joint is loose. Solution: Reconnect the connector.

　　h, the drain pipe is dirty with foreign matter. Treatment method: the drain pipe is dirty and blocked by foreign matter.

　　 Flood warning linkage shutdown processing method:

　　 The computer room air conditioner will have abnormal refrigerant pressure when running for a long time, which will cause the evaporator to freeze and the drainage pipe to block problems, especially in the rainy season. The increase in air humidity can easily produce a large amount of condensed water dripping onto the ground. If this situation occurs, if it cannot be treated in time, it will affect the operation of the equipment. In addition, the ground water will endanger other equipment and cause safety hazards.

　　 At present, the computer room is unattended, and the air-conditioning leakage monitoring depends on the flooding probe of the power environment monitoring system. When a water leak occurs, even if the water immersion probe collects this fault, it can only be notified to the maintenance personnel through a work order or IVR phone after being uploaded to the network management system. The air conditioner cannot be turned off in the first time. The maintenance personnel will Water leaks continuously.

　　 Add a water immersion probe to the place where the internal unit of the air conditioner is prone to water leakage (such as the evaporator tray, drain pipe, etc.) to expand the range of collection and early warning. At the front of the air conditioner power supply, an AC contact controller, Two intermediate relays and a spring return switch form a secondary control loop, and are connected with the monitoring acquisition board through a data line. The opening and closing instructions for linkage control of the auxiliary contacts of the intermediate relays are set in the monitoring system background instruction software database, and monitoring The system realizes the dual connection of power and signal. When the computer room air conditioner has a flood warning, it will automatically shut down immediately to minimize the amount of water dripping and buy more time for maintenance personnel to rush to the scene to deal with it. Up to now, the program has been installed on a pilot basis in some computer rooms, and has been repeatedly verified, with a success rate of 100%. The successful practice of this project has made the air-conditioning flood warning mechanism in the original dynamic environment monitoring system more intelligent and automated, and greatly reduced the scope and harm of water leakage.

　　 How to deal with flooding in the computer room:

　　 First block the leaking source, turn off the central air-conditioning unit according to the water inflow, and pull down the main power switch. If the water leak is large, The supervisor of the equipment department should be notified immediately, and at the same time, try to stop the water inflow. After the leaking source is blocked, drain the water immediately; after draining the water, the wet water equipment and facilities should be dehumidified immediately, such as wiping with a dry clean cloth, hot air Dry, naturally ventilate or replace related pipelines, etc., confirm that the wet water has been eliminated, and after the insulation resistance meets the requirements, start the trial operation. If there is no abnormal situation, it can be put into normal operation.

　　 For the reason of water leakage, remind engineers to observe whether the machine is level and whether the wall hole is higher than the machine during the installation of the air conditioner in the computer room. In the process of use, the filter should be cleaned frequently to avoid water leakage and improve the cooling efficiency. The drain pipe should not be moved or knotted. There are different remedies for leaks of different reasons. If the drain pipe is broken, you only need to replace the drain pipe at a small cost. If it is ‘dirty’, clean the blocked section of drain pipe.

　　About the evaporator problem:

　　The evaporator in the air-conditioning room of the computer room freezes, causing water leakage when it melts. There are three treatment methods: 　　

　　1. The system lacks fluoride and adds fluoride.　　

　　2, cleaning the air duct system.　　

　　 3. The wind speed is abnormal, adjust the wind speed to normal.

　　About the indoor connecting pipe problem:

refrigerant gas start capacitor suppliers, as the name suggests, find extensive use in start capacitor suppliers institutions. Since start capacitor suppliers has become much dependent on technology in today's world, there is wide use of such air conditioner capacitor.
