Speaking of for HVAC, well…predictive maintenance is quite important for HVAC systems. Simply put, it is to collect various data and use various technical means to predict when there will be problems in the equipment, and prepare for maintenance and maintenance in advance. This can enable the HVAC system to operate stably and save some operational costs.
Let's talk about the key things in detail below
First, data collection. We have to collect a lot of data in the HVAC system
1. Basic parameters like system operation. For example, the temperature is uh, what is the temperature in the room at different times; there is also pressure data to see the pressure stability, etc. The abnormal temperature is too high, which may actually indicate that the refrigeration part is in trouble; the pressure is unstable, and there is a possibility of leakage of the pipeline.
2. What is the current and voltage of equipment, such as motors, and the current and voltage of key components? It can intuitively reflect the working conditions of the equipment. The current suddenly increases? It might be that the parts are stuck
The second key content is data analysis. After collecting data, you have to dig through useful information.
1. Use some methods of traditional data analysis. The data that used to run normally and now is collected is compared. If there is any deviation, the cause of deviation must be studied. Comparison of the same time period in different years.
2. The emerging means of machine learning algorithms! Applications like neural networks can predict faults very accurately after training the model.
Then we have to talk about pre-executing maintenance actions! Based on data analysis, we see possible failures, so let’s follow the following!
1. Simple maintenance like parts cleaning. For example, the air filter is washed regularly. If it is not clean, it will affect the system's operating efficiency and increase energy consumption.
2. Prepare parts replacement in advance. It is discovered that key components may end up in their lives. Then hurry up from Curry or buy new ones to replace them Hey.
Let’s talk about some common questions in Q&A.
Q: Predictive maintenance compared to traditional maintenance methods? Answer: Traditionally, regular and fixed processes are used to maintain, but the equipment may be well-timed, resulting in high maintenance costs; predictive maintenance is carried out using technology as needed to avoid unnecessary maintenance.
Ask for the long term, the cost is obvious? Answer: The short-term investment in technical equipment and software costs can reduce the number of repairs in the long run and the use of parts is more efficient, and the overall cost reduction is quite clear!
There is also a global procurement service for weak current intelligent products that can ensure that there are more high-quality choices in equipment product selection.
In my opinion, for HVAC is definitely an important direction for future development. It will definitely greatly improve the reliability of the HVAC system and save our operators more worry. It will reassure the owners of the
