So how can so many systems learn reasonably and effectively? This involves the importance of learning order, accurately find the learning skills of installing the system, and learn from easy to difficult. No matter what kind of system you learn, it is a learning method to know the map first, then calculate the quantity, and finally set the price. At the same time, you must be familiar with your local calculation rules, which will play an important role in calculating the quantity. Calculation rules are like guns in the hands of soldiers. How to fight without a gun is doomed to the end before it starts.
Back to the topic, with so many systems installed, let's talk about the learning order of these systems first:
The first step: learn water supply and drainage, heating system and gas system (the pipes of these systems are very common in the family and easy to understand);
Step 2: Learn the ventilation and central air conditioning system in air conditioning system (you can see it in hospitals or shopping malls, although you can't see the fan coil, you can strengthen your understanding by combining the actual situation and pictures);
Step 3: Learn the lighting socket and lightning protection grounding in high-voltage system (lamps and sockets are available at home, so you can observe them carefully and deepen your understanding with principles; Lightning protection and grounding are also inseparable from life. You can go to the roof of residential buildings to see the lightning protection network, but you need to understand the principle of strong electricity and their basic knowledge first.
