An operation and maintenance management system and method for a heating, ventilating and air-conditioning system

Abstract

The invention discloses an operation and maintenance management system and method for a heating, ventilating and air-conditioning system. The system comprises a field operation terminal, a customer management terminal, a repair report management terminal and a processor. Information is input through the field operation terminal and transmitted to the processor. The maintenance task sent by the processor is received and the maintenance progress is fed back to the processor. The key data, system comprehensive evaluation indicators, equipment operating status, failure maintenance progress and maintenance protection basis, and audit the maintenance workflow are acquired from the processor through the customer management end; the fault report work order is uploaded to the processor through therepair report management terminal, the fault repair progress feedback from the processor is received, and the efficiency of the repair work is evaluated; the processor establishes the equipment maintenance plan, evaluates the equipment status, identifies the equipment operation failure, and records the repair progress fed back by the field operator, and analyze and evaluate the system stability, energy consumption index, repair processing rate and data input integrity according to the data recorded by the field operation terminal.

Description

technical field [0001] The invention relates to an operation and maintenance management system and method for a HVAC system. Background technique [0002] At present, my country's building energy consumption accounts for one-third of the total energy consumption of the society. With the improvement of living standards, building energy consumption continues to increase, and building air conditioning system energy consumption accounts for about 40%-60% of building energy consumption. Therefore, the design, selection, installation, operation, and maintenance of central air conditioning are very important, which determine the quality of the entire building, especially the operating cost of the building. However, many people often do not pay attention to the air conditioning system. On the one hand, they ignore the management of the air conditioning system, and on the other hand, they complain that the operating cost of the air conditioning system is too high! If the user select...

AI Technical Summary

Problems solved by technology

[0004] Due to the low professional level of the operating personnel, the projects equipped with automatic control systems have basically become decorations or have not been put into operation at all. Most of the computer rooms have a low degree of automation, or the lack of dedicated maintenance personnel leads to system paralysis; There is no data support for maintenance costs, and the recorded data is a paper version, so it is difficult to guarantee the authenticity, and it is difficult to enter data analysis; it is difficult to guarantee safe and stable operation, and it is impossible to reduce the rate of customer complaints; property management personnel lack indicators for operation assessment; management Those who are unable to remotely monitor the usage of the system, rely more on routine inspections, and it is difficult to keep track of system trends at any time, often only after a failure occurs to remedy, most of them are late-knowing, unable to prevent problems before they happen

[0005] Repair reporting is mainly by telephone notification. Taking hospitals as an example, the cause of the accident is often judged based on experience based on the description of the head nurse or the repairing personnel, and it cannot be visualized.

This will affect the timeliness of maintenance

Maintenance confirmation is often subject to verbal notification or the signature of maintenance records. Once the head nurse or repair personnel are temporarily absent, the records will be missing, and the feedback rate of repair reports cannot be guaranteed

For the common problems reported for repairs, there is no classification statistics, which cannot provide a basis for partial renovation

[0006] To sum up, in the prior art, for the operation and maintenance management of the air-conditioning system, data analysis and input are very difficult, and it is difficult to ensure the safe and stable operation of the air-conditioning system. There is a lack of assessment of the management personnel, and the managers cannot remotely monitor the usage of the system. problem, there is still no effective solution
