Cause analysis and detailed introduction of air conditioning not cooling in high temperature weather

Everyone found out! Nowadays, many families have installed air conditioners. With air conditioning, we are no longer afraid of sultry summer. Have you ever encountered such a problem when using air conditioning? That is, the hotter the weather, the less the air conditioner cools. I believe many people have encountered such problems! In fact, there are many reasons why air conditioners don't cool in hot weather. Then Bian Xiao will give you a good analysis of the reasons why air conditioners don't cool.

Cause analysis of air conditioning not cooling in high temperature weather;

1.？ Sensor failure

The failure rate of the coil temperature sensor of the internal heat exchanger is the highest, even if it is not broken, the failure rate detected by it is relatively high. So if you think it may be a sensor problem, you might as well check it and replace it. Poor contact of air conditioner connector is also one of the reasons leading to many failures.

2.？ fluorine deficiency

It is also a common problem. After working for a period of time under the protection of air conditioning, we should first check whether the cooling effect is good. If it is not good, it is necessary to measure the three pressures of the air conditioner, the equilibrium pressure and low pressure of refrigeration, and the equilibrium pressure and high pressure of heating.

3.？ Power supply voltage problem

The problem of voltage is also very prominent, especially in the peak period of electricity consumption. When the three-phase air conditioner can't start, the first thing to check is the phase sequence. ? The key points of power supply inspection of air conditioner are whether the contacts (of air conditioner and main power switch) are burnt and corroded, whether the contacts are poor, whether the internal contacts of main power switch are good, whether the current resistance is satisfied, whether the main power supply line is too long and too thin, and whether the voltage is lower than 200V V? Whether the zero line and the ground wire are mixed, whether the three-phase line and the zero line are mixed, etc.

4.？ Other issues

Pressure protection, especially when the outdoor refrigeration of refrigerator is not good in summer. Compressor overload protection is very common in summer when the temperature is high and the power consumption is peak. The circuit of remote control receiving and display board is also prone to failure, and voltage measurement and substitution are the best choices. For places with poor environment. It is necessary to mainly check whether there are mice biting on the internal and external connections and indoor wires, which is a frequent failure, and whether the circuit board and buttons are damp. The joints of extended pipes and lines between internal and external machines are also frequent points of failure. The requirement of wire connectors is to wrap them with waterproof insulating tape after welding, but some installers just screw them together and wrap them with ordinary tape.

The analysis of the reasons why air conditioners don't cool in hot weather is here for everyone. I hope Bian Xiao's introduction today can help you solve this puzzle. Of course, there are many kinds of air conditioning failures in daily life. As long as you have more contact, you will gradually master the troubleshooting methods of air conditioning faults, and you will be invincible at that time. Generally, air conditioning faults can be solved. The use of air conditioning can reflect the living standard of a family from the side, so I believe that every household can use air conditioning in the future.
