What is the reason why the air conditioner doesn't cool for a long time?

1. Check whether the air conditioner works normally, including indoor units and outdoor units, especially outdoor compressors. As long as one of them is abnormal, please ask the air conditioner maintenance master to have a look.

2. Check the air conditioner filter. If the air conditioner works normally, but it can't dispel the chill, it is likely that there is too much dust in the air conditioner filter. Spray it with a special filter cleaner and clean it.

3. Check whether there is a lack of refrigerant, which is often called freon. If refrigerant is lacking, fluoride should be added. Check carefully whether the air conditioner leaks water together. This kind of situation often appears in air conditioners that have been used for three or four years, which is also a normal phenomenon. However, this situation will only lead to no refrigeration. If there is no refrigeration at all, check carefully for air leakage.

If the air conditioner works normally and there is no such phenomenon, you can check the working condition of the electric fan. If the air volume of the electric fan is very small, it is likely that the electric fan motor is aging, and the electric fan motor can be replaced.

5. Check whether the air conditioning ventilation pipe is too long. The ventilation pipe is too long, which will affect the effect of indoor heat conduction to the outside. It is advocated to change the orientation of outdoor air conditioners and shorten the ventilation pipes as much as possible.

6. If the air conditioner works normally, only the air conditioner fan has coolness, and the other directions of the room can't feel coolness or the effect is not obvious, then it is likely that the horsepower of the air conditioner is too small and the room is too big, and it is advocated to replace the air conditioner with larger horsepower.

How to repair the common problems of air conditioning?

1, air conditioning power supply

Maintenance method: burn out the safety tube and safety tube when starting. Business telephone

1, our representative will provide you with professional answers!

Safety tube: it means that there is a short circuit in the circuit. Use a multimeter to detect the resistance and determine the short circuit position. Together, we can also use the method of splitting to check. For example, we can disconnect the primary winding of the transformer and power on the tester. If it is not ready, clarify that the burning is due to the short circuit of varistor or ceramic chip capacitor, transformer or rectifier.

Safety tube: use a multimeter to communicate with the gear, and measure whether the secondary and primary voltage of the transformer reach 220v and10-13v. If yes, use a multimeter to measure whether 78 12 and 7805 have +9- 12 volts and +5 volts, which can effectively distinguish faults.

2, air conditioning relay circuit

Maintenance method: The difference is that the relay is damaged or the integrated power drive module is damaged.

The buzzer sounded after starting, and the whole machine could not work, mostly because the integrated power drive module was damaged;

After starting, some functions are abnormal, mostly relays are damaged. Listen to the pull-in sound of relay, and judge whether the relay is contact adhesion or coil burning.

There is no pull-in sound, indicating that the relay coil is burnt out;

You can also use a multimeter to judge whether it is good or bad. Turn off the power supply and measure the coil resistance first. Generally speaking, the normal resistance value is several hundred ohms. If it is infinite or 0, the relay is damaged.

Measure the contact. If the resistance value is 0, it means that the contact is stuck.

3, air conditioning temperature sensing circuit attack problem.

Maintenance method: the thermistor is a negative temperature coefficient resistor, and the lower the temperature, the greater the resistance;

At 25 degrees, the resistance is about 5-20kΩ. It can be measured by multimeter ohm, and the resistance value is very small or infinite, indicating that the thermistor should be replaced if it is damaged.

4, air conditioning reset circuit

Maintenance method: reset voltage is a delayed rising voltage, which can be investigated by DC voltage of multimeter.

If the investigation is not clear, then use an oscilloscope to detect it. During the test, I saw a baseline floating and then turned to high level, which is the starting process of the reset voltage. If the baseline does not float, it is obvious that there is something wrong with the reset circuit.

5, air conditioning remote control receiving circuit

Maintenance method: Start the machine, and measure the voltage between the signal end and the ground and the power end of the receiver with the multimeter DC range. The normal value should be +5V at the power terminal and +2.5V at the signal terminal. Common faults are capacitor breakdown or receiver head damage.

The drain pipe is mainly used to drain the condensed water from the indoor unit. When connecting with the indoor unit, use soft connection and clamp it with a clip. If the connection is not tight, condensed water will flow out of the gap.

The solution is here: after the indoor unit is connected with the drainage pipe, conduct a drainage test to ensure that the connection is tight and there will be no water leakage.

3. Poor condensate discharge

Clogged condensate outlet of indoor unit or insufficient slope of drainage pipe will lead to poor drainage and accumulation on the water tray of indoor unit. When the water dish is full, it will overflow to soak smallpox.

See the solution here: during construction, ensure that the drainage slope of condensate water is not lower than1100. Before connecting the drain pipe to the indoor unit, please check whether the outlet of the indoor unit is dirty or blocked. After the drainage pipe is completed, ensure that the condensed water can be discharged smoothly.

4. The drain pipe is not insulated.

The temperature of condensed water flowing through the condensed water drainage pipe is low, so it is necessary to pack thermal insulation cotton during construction. In order to save costs, some engineering companies don't wrap thermal insulation cotton on the condensate drain pipe, which leads to condensation on the outer wall of the drain pipe and water leakage.

Solution: All condensate drainage pipes must be wrapped with thermal insulation cotton, and the standards and requirements for wrapping thermal insulation cotton are the same as those for copper pipes.
