Can the low success rate of refrigeration activity resonate?

Yes, I'm a layman when I repair refrigeration. If you want to repair a freezer, how many TVs can be repaired, don't look at its high profits, it may not be cost-effective Eighth floor, I don't have to repair the refrigeration and don't necessarily lose it, because the cost of my coil is equal to the user's own refrigerator and freezer sold and then go to the second-hand door to buy a second-hand door of the same size. So most of the users don't fix it.

Of course, it will not be stronger than repairing refrigeration, after all"The art is not pressing, and the art master is bold", Besides, there are still repairs, but there are too few in me. It seems that I have a difference with everyone in this aspect, maybe it is the lack of refrigeration, but my civilian refrigeration work is really rare, and the success rate is very low.

Refrigeration is not difficult to repair, it is much simpler than electronic circuits, and the profit is okay. Maybe the refrigeration technology of the landlord is not enough to pass the test. However, it takes a long time for the refrigerator to be repaired and debugged (in fact, the actual workload is not large), and it is really not profitable to make money if it is repaired at home, which is too wasteful of time.

Maybe you have some truth in what you're saying! It should be related to the local economy and customs Ask many peers and friends around,They also repair everything,But they all directly or indirectly expressed their preference to repair the TV, even if the money is less,Unwilling to repair the refrigeration View the original post

Is refrigeration not easy to repair? Where is the landlord? And those who sell tools?

I'm going to sell the tools to fix the TV and specialize in high refrigeration. Refrigeration is the money! There are one or two cold storages and one or two ** air conditioners a year.

It's been a year for you to fix the TV, haha. It's not that you don't do it, it's that you need to be technically proficient! View the original post

Everybody knows that! Refrigeration is more expensive than repairing a TV. Whenever the season comes, I turn down TV and focus on refrigeration. And there is absolutely no anti-repair. I think it has something to do with the local economy! View the original post

It should be that refrigeration is simpler than TV, and the profit is better. Half of my repair income is refrigeration. (The refrigeration problems are all pulled to the store to be repaired) View the original post".

Repair refrigeration labor, repair TV labor. Each has its own advantages and advantages. It's good to repair the refrigeration. View the original post

It should be said that the profit of repair and refrigeration is okay, but it is too wasteful of time, and the repair rate is not high. View the original post

I don't repair the refrigeration either.,It's very simple.,I won't.,Haha,Sales can be done.,Repair that won't.。。 Generally, I look for a master.,I'm mainly repairing TVs.。。。 View the original post

If you don't repair the refrigeration of electrical appliances, it's a big loss for youView the original post

The refrigeration rate should be lower than that of the TV, and the profit is also higher than that of the TV! View the original post

Refrigeration should have a lower rate than TV renovation, and the competition for money is more than repairing TV View the original post

No way! Refrigeration is the money! Do your best! View the original post

Thailand is higher than the domestic level, not only the success rate is also much higher than the domestic level, so the Thai IVF technology is much more mature than the domestic one

If most people can't hear it, it proves that they don't, and only you hear it, it's because you have some mental breakdown, and you are more sensitive to sound, so take some soothing medicine.

This is the reason for the same frequency. Knowing this, it's easy to solve, and you can use anything to pad the fuselage. It is also possible that the fixing screw of the motor was sent and mistakenly thought that it was resonance, and it is good to tighten the screw, just for reference.

It is likely to be caused by overfilling the refrigerant, and the current and tube pressure of the compressor must be checked. It is also necessary to check whether the fasteners are normal.

The fan plastic is deformed. If you want a horse, the hanging board is not fastened.

The water pipe does not drip Check it, the pipe is not connected, is there a blockage, it is good and bad, that is the compressor is faulty, call ** to customer service, let it be repaired, it is very hot in summer, hurry up and repair it, thank you for the reminder, if it is bad, it will be called repair. Hehe, it's better to find a repair as soon as possible, while it can still be used now, otherwise it will suffer in the heat.

Dripping, this is related to the principle of air conditioning. The compressor of the air conditioner compresses the refrigerant, and then expands it through the valve, because the expansion wants to release heat, so that the temperature of the refrigerant is reduced, and then the refrigerant flows into the indoor evaporator, absorbs the heat of the indoor air through the contact between the evaporator and the indoor air, and then compresses it and expands again, so that the reciprocating circulation takes away the heat of the indoor air little by little. Since there is a lot of water vapor in the air, the evaporator will turn into water when it encounters a very low temperature.

Is it smoking, could it be the air conditioner defrosting?

It is estimated that the heat exchanger absorbs heat from the outside during heating, the temperature of the heat exchanger is low, there is water in the air, the evaporation gas gradually frosts, which affects the heat exchange effect, if the air conditioner has a defrosting function, the frost will be removed, and the frost will naturally melt into water, and the hot wind blows, of course, it is white smoke.

In short, let the maintenance personnel repair it.

The success rate of starting a business itself is low, and it has nothing to do with programmers.

However, there is some truth in its point of view, programmers, R&D personnel, etc., all belong to a relatively characteristic work group, and I still agree with the analysis and judgment from the characteristics of this group. For example, focusing on one thing (which may lack flexibility), having a relatively weak sense of teamwork, etc., are all minus points when it comes to starting a business.

From the perspective of the quality of entrepreneurs, this is indeed the case.

Of course, this does not negate this group, not to mention that the success rate of entrepreneurship itself is very low. Therefore, if you are a programmer, you should start a business, just pay attention to some problems. No one is perfect, so why not other entrepreneurs?

So don't dwell too much on these issues.

I recommend Wang Guozhen's poetry.
