Maintenance content of high-precision constant temperature and humidity air conditioner for computer room:
First, maintenance and maintenance of high-precision constant temperature and humidity air handling unit for computer room
1. Make sure the surface is clean, the rotating parts of the fan are free of dust and oil, and the belt rotation has no abnormal friction.
2. The filter is clean, the filter material is not damaged, the air vents are not blocked, and there is no deformation.
3. The evaporator fins should be bright, unblocked, and free of stains.
4. The fin sink and condensate tray should be clean and free of sediment, and the condensate pipe should be unobstructed.
5. There is no running, bubbling, or air leakage in the supply and return air ducts and static pressure boxes.
Second, maintenance and maintenance of high-precision constant temperature and humidity air-cooled condensers for computer room
1. The fan support is tight, the base is not loose, and there is no weathering. The motor and fan blades should be free of dust and oil, and the fan blades should rotate normally without shaking and friction.
2. Regularly test the working current of the fan with a clamp ammeter and check the speed regulating mechanism of the fan to see if it is normal.
3. Check and clean the condenser fins frequently, and there should be no dust and oil. No water enters the junction box and the fan.
4. The bearing of the motor should be a tight fit. If the fan blade swings or rotates abnormally, it should be repaired or replaced.
Third, the maintenance and maintenance of the compressor part of the high-precision constant temperature and humidity air conditioner dedicated to the machine room
1. Use high and low pressure Freon meters to test the high and low pressure protection devices, and eliminate problems in time.
2. Frequently touch the surface temperature of the compressor with your hands to see if there is overcooling or overheating. If a large temperature difference is found, the cause should be found out.
3. Regularly observe the flow of Freon in the mirror to determine whether there is moisture or lack of liquid.
4. Check whether the fixed position of the refrigerant pipe is loose or vibrating.
5. Check the insulation layer of the refrigerant pipeline. If it is damaged, it should be repaired in time.
6. The refrigeration pipeline should be unobstructed, and blockage should be eliminated in time.
Fourth, the maintenance and maintenance of the humidifier part of the high-precision constant temperature and humidity air conditioner dedicated to the machine room
1. Keep the humidification water pan and humidification tank clean, and remove scale regularly.
2. Check the water supply and drainage pipelines to ensure smooth flow, no leakage, and no blockage.
3. Check the action of the solenoid valve, the humidification load current and the working condition of the controller, and eliminate the problems in time.
4. Check the electrodes and far-infrared tubes to keep them intact and free of dirt.
Fifth, the maintenance and maintenance of the electrical control part of the high-precision constant temperature and humidity air conditioner dedicated to the machine room
1. Regularly check whether the alarm sound and light alarm are normal, whether the contactor and fuse are loose or damaged, and eliminate the problems in time. Check whether the fire alarm system is normal.
2. Check whether the screws of the electric heater are loose and whether the heat pipe is dusty. If there is looseness and dust, it should be tightened and cleaned in time.
3. Use a clamp ammeter to test the load current of all motors. When the measured data does not match the normal value, the cause should be found and eliminated.
4. Check whether the relays and electronic components are damaged and deteriorated, and replace them in time if problems are found.
5. Use a dry-bulb thermometer to measure the return air temperature and relative humidity. If the deviation exceeds the standard, it should be adjusted.
6. Measure the protective grounding wire of the equipment. If the lead wire is in poor contact, it should be tightened in time.
7. Measure the insulation of the equipment and check whether the wires are aging.
Sixth, the working condition test of the high-precision constant temperature and humidity
    air conditioner for the computer room should be tested once a year to timely grasp the performance of the main equipment of the system, and to carry out targeted repairs and adjustments to the air conditioning system equipment to ensure stable and reliable operation of the system. According to the above inspection and test results, take corresponding maintenance measures to keep the high-precision constant temperature and humidity air conditioner for the computer room in good operating condition.
