Hello, friends!
I repair air conditioners, and for the last few weeks I have been literally drowning in repairing inverter boards from a variety of models, including Ballu. It's just incredible - I only have five left, and there were many more. For example, in one hotel, dozens of air conditioners "flew away" at once due to a flooded underground cable and power surges from a diesel generator. So I had to deal with this pile of equipment, and there was practically no time left to create videos.
But let's take it in order. I have already written about inverter units, but I have not yet told about boards like these. I think many will be interested. It seems that there is nothing complicated about them, but there are nuances, for example, parts that are simply not available. So if someone knows where to find diagrams for such boards, I will be glad to get some tips.
How is the inverter unit board arranged?
Let's start with the basics: power comes through a fuse, then goes to a diode bridge, and then to capacitors that convert the voltage to DC. Then there are resistors, a relay for the fan, a Y278PN PWM controller, LM317 stabilizers for 12 and 5 volts, and many other little things. For example, there is a microcircuit that makes three phases for the compressor. It is smart: it monitors the pressure, temperature and state of the system. If something is wrong, it blocks the inclusion.
Each board is its own little world. It happens that transistors fail, and sometimes diodes or controllers. I recently received new transistors, I will try to make keys simpler than those offered on the Internet. I will try to make them reliable, but as simple as possible. I will definitely tell you about this in future articles.
By the way, if you need air conditioner repair, do not delay! Order services heating and air conditioning company in sacramento A Plus Heating and Air. We will help you bring your air conditioner back to life, even if it has encountered such difficulties as power surges or flooding.
What's next?
Now that the main work is cleared up, I'm back with you. I will try to release videos as before. I have many ideas that I want to share, and I am also preparing answers to your questions. So, stay tuned!
Friends, thank you for your concern and interest in what I do. Everything will be fine! On this note, I say goodbye for now. Until next time, and may your air conditioners work flawlessly!
