The central air-conditioning wind system, which is an important component of the air-conditioning system, is primarily responsible for the distribution of cooling or heating air to the rooms in order to reconcile indoor temperature and humidity. Wind systems typically consist of wind machines, wind valves, filters, silencers, etc., whose operational status directly affects air conditioning performance and indoor air quality。
I. Common failures of the central air-conditioning wind system
Inadequate wind: may be due to wind failure, filter congestion, damage to wind valves, etc. At this point, wind machines, filters, wind valves etc. Need to be inspected and repaired。
Over-noise: it may be due to the malfunctioning of wind machines, loose wind pipes, failure of wind valves, etc. At this point, wind machines, wind pipes, wind valves, etc., need to be checked or replaced。
3. Leakdrops: this may be due to poor discharge of condensed water and the breakdown of pipes. At this point, the condensed water discharge pipes need to be inspected and repaired or broken pipes replaced。
4. Inappropriate air handling: this may be due to inadequate refrigerants or leakages, poor air circulation, etc. At this point in time, refrigerants need to be inspected and repaired or air-cycle pipes need to be inspected and cleaned。
Ii. Central air-conditioning wind maintenance concerns
1. Periodic inspection: the wind system should be regularly inspected, including the operational status of the wind engine, the cleaning of filters, the flexibility of the wind valve switch, etc., in order to detect problems and address them in a timely manner。
2. Maintenance operations: operation should be carried out in accordance with the maintenance specifications provided by the plant, regular cleaning of filters, replacement of lubricant, etc. To ensure normal operation of wind machines and extension of the service life of the equipment。
3. Maintenance services: in the event of a wind system failure, the manufacturer or professional maintenance staff should be contacted in a timely manner for maintenance. During maintenance, care should be taken to protect other parts of the equipment from unnecessary damage。
Operator training: equipment operators should be trained in the correct operation and maintenance methods to avoid equipment failure due to inappropriate operations。
5. Safety operations: care should be taken during maintenance to avoid accidents. For example, when cleaning filters, care should be taken to avoid the air pollution caused by the breakdown of filters; when replacing pipes, care should be taken to avoid leaking water。
Storage environment: equipment should be stored in a dry, well-ventilated, sunlight-free environment in order to avoid malfunctioning due to adverse environmental conditions。
Electrical security: the electrical component of equipment should be regularly inspected and maintained to ensure its safety and reliability. At the same time, care should be taken to use electricity safely during maintenance and to avoid electrical accidents。
8. Spare parts reserve: some commonly used spare parts, such as bearings, seals, belts, etc., should be stored to allow timely replacement in emergency situations。
9 archives management: an equipment archive should be established to record the equipment's model, specifications, installation debugging and maintenance to provide a comprehensive understanding and management of the equipment。
Technical support: timely technical support and after-sales services should be provided to address user problems in use. At the same time, relevant technical and training materials should be made available to users to enable them to better understand and use the equipment。
