Do centrally placed inverters need an air-conditioned room?
Thread Content
The ambient temperature is 40°C in summer, which is relatively hot, and there is dust in the air.
The frequency converter has relatively high requirements on the surrounding environment and requires the installation of air conditioning. There is a lot of dust in the air, so it is best to move the frequency converter to a relatively clean place and it needs to be purged regularly.
Control rooms where frequency converters are concentrated, especially large-capacity frequency converter control rooms, should be equipped with air conditioning equipment to ensure normal operation of the equipment in summer.
According to the conditions of the inverter control room you mentioned, air conditioning must be added. The operating environment of the inverter is generally -10℃-----+40℃. If the ambient temperature is above 40℃, it needs to be derated. If the ambient temperature is too high, the use of the inverter will be affected. The environment in which the frequency converter is used must be dust-free. Generally, the protection level of the frequency converter is IP20, and the frequency converter is forced air-cooled. If the environment contains dust, the dust problem must be solved. The operating environment of the inverter is described in detail in the instruction manual, which may differ from manufacturer to manufacturer. Read the instructions carefully before use and try to avoid operating the inverter in harsh environments. This post was last edited by chinahbzq on 2009-2-25 14:58 ]
You are welcome. Everyone shares their experiences here, which will help and improve themselves and others. Lots of discussion. :)
It's best to have one, as this will reduce the failure rate and make the investment absolutely worth it in the long run!
It should be true that many units believe that the temperature range specified in the inverter manual is relatively high, and if they do not take effective measures to reduce temperature and dust, the reliability of the inverter operation will be reduced and the probability of component damage will increase.
http://bbs.hcbbs.com/viewthread.php?tid=399187&page=1#pid2131018 You can read this post, which is my current situation. My factory in Guangzhou does not have a separate inverter room. There is a boiler and an electrical cabinet. The electrical cabinet includes the PLC system and the inverter. Of course I know this is not good, but why do we still do it? ? ? (This was the case before I came to the company) I will consider centrally placing inverters in the new factory, adding air conditioning, and filtering dust. Thank you all!
It is recommended to use air conditioners, and to add exhaust fans and dehumidifiers in places that are not very hot, because there are electronic components inside the inverter, and the best temperature for electronic components to operate is between 10-30°C. We have added air conditioners here, and it is good to use the inverter.
Our company's inverters are all centrally placed and air-conditioned. And there are two air conditioners, keeping the indoor temperature at about 25 degrees. The heat dissipation of the inverter is very important. High temperature may cause it to trip.
Our company uses air conditioners and is equipped with two units. Make sure at least one is available.
The use of air conditioning is necessary. Generally, the environmental requirements of the inverter are -10-40 degrees. However, when it is above 40 degrees and below 50 degrees, you need to consider reducing the load, otherwise the internal components of the inverter will be burned due to overheating. Regarding the dust problem, even if the temperature in the air-conditioning room is low and the fan is running uniformly, the impact of dust on the inverter is not much better. Therefore, dust-proof facilities must be adopted or installation in a low-dust area must be selected.
It's best to have it, otherwise the inverter will often alarm
