1, heating operation for 5- 10 minutes without wind? Normal.
Answer: During defrosting (low outdoor temperature and high machine temperature will automatically defrost) 5- 10 minutes.
2. When dehumidification is running, it is often sent out without wind?
Answer: It is normal to prevent wet water from re-evaporating to save energy. A moment, please.
3. Does the external machine not start after shutdown?
A: The air conditioning system has a three-minute delay protection function, and it takes three minutes to make the whole system work after shutdown.
Pressure balance to prevent the pressure from being too high when the press is started, and prolong the life of the press.
4. Why sometimes the remote controller doesn't display the temperature?
A: In automatic and air supply modes, the remote control does not display the temperature. In automatic operation, the air conditioner automatically selects the cooling, heating or air supply mode according to the indoor temperature. (General refrigeration: above 23 degrees; Heating: below 23 degrees; The temperature is controlled within 26 degrees. )
5. Air conditioning refrigeration operation. After the compressor stops working, why does the outdoor fan have to run for a while?
Answer: During refrigeration operation, the temperature of outdoor heat exchanger is relatively high. After the compressor stops running, the outdoor fan will continue to run for a period of time, so as to discharge the heat of the external machine and quickly reduce the system pressure, thus realizing the smooth start of the air conditioning compressor after the delay protection time.
6. Why does the small split hook sometimes make noise when the air deflector is open?
Answer: In order to ensure the accuracy of the setting position of the air deflector after startup, the computer program sets the air deflector to reverse a certain angle when startup, so that the air deflector is completely closed, and then rotates at the preset angle of cooling and heating memory at the beginning, so the traditional delay of closing the air deflector is 6 seconds when startup, and the gear will make a "click" sound.
7. What should I do if the remote control is garbled or the screen crashes?
Answer: Put a thin object into the small hole of the reset button and press it, or take out the battery and put it in, and the remote controller can be restored to its initial state.
8. Why doesn't the air conditioner turn on when it is plugged in?
Answer: In order to start the compressor at low temperature and play a protective role, the compressor is equipped with an electric heating belt and preheated. The heating belt (power is 27-33W) and the transformer (power is 3-7W) start to work after being plugged in, so the meter will still rotate when there is no power supply, but the power consumption is very small.
9. Why does the air conditioner turn on and off frequently?
Answer: (1) The temperature difference between the set temperature and the room temperature is too small.
(2) The cooling area of the room is too small relative to the air conditioner.
(3) There are windproof objects around the indoor and outdoor units of the air conditioner.
10. How to set the position of the air deflector more reasonably?
Answer: When cooling, the air deflector of the air conditioner should be set in the horizontal direction, and cannot be blown vertically downward to prevent the air deflector from condensation; When heating, the air deflector should blow down to make the indoor cold and hot air convection and the temperature more balanced.
1 1. When the air conditioner is heating, the indoor temperature reaches the set temperature and the outdoor unit stops. Why is the indoor unit still running?
Answer: During heating operation, after the outdoor unit is shut down, the indoor unit runs in "breeze" mode, which can blow out the residual heat of the indoor unit and protect the air conditioner.
12. When the cabinet is hot, why can't the wind speed be adjusted sometimes?
Answer: When the cabinet is mechanically heated, when the outlet air temperature is lower than a certain temperature, the wind speed is forced to be low; When the temperature is higher than a certain temperature, the wind speed is forced to be high, but when the wind speed is forced to be high, the wind speed cannot be adjusted. This is a computer internal protection program, which is a normal phenomenon.
13. Stop working when the air conditioner is heating. What is the reason?
Answer: Because the hot air is light and concentrated in the upper part of the room, the temperature detected by the room temperature probe of the indoor unit is higher than that of the lower part of the room, so there is a certain temperature difference between the set temperature of the remote controller and the room temperature. At this time, the set temperature of the remote controller should be 4-6 degrees higher than the ideal ambient temperature.
14. Why don't the buttons on the cabinet panel work sometimes?
A: Generally, the "crash" phenomenon is caused by abnormal voltage. At this time, restart the machine after power failure; Some cabinets have electronic lock function. It is possible that the user has set the electronic lock function. When the electronic lock function is set, the panel button is locked and cannot be operated normally. Only when the electronic lock function is cancelled can the panel keys be operated.
15, air conditioning refrigeration effect is good, but why do indoor units sometimes spray water fog?
Answer: When the ambient humidity is high or the ambient temperature is low, after the heat exchange between the air and the indoor heat exchanger, the moisture in the air condenses and blows out with the wind, resulting in water mist.
16. What checks should be made when the air conditioner is not turned on?
Answer: (1) Is there electricity in the power supply (power failure)?
(2) Whether the power plug is in good contact
(3) Whether the battery of the remote controller has power (if the power is insufficient and the transmitted signal is weak, it is not easy for the receiver of the indoor unit to receive it).
17. When the air conditioner is running, the indoor unit sometimes makes a "wow-wow" sound of running water or a "goo-goo" sound. Why?
Answer: This sound is a normal sound made by refrigerant flowing in the pipeline, not a machine failure.
18. Why does the air conditioner sometimes make a lot of noise when it is just turned on or stopped?
Answer: When the compressor suddenly starts from the static state, the pressure in the system is unbalanced, and the refrigerant suddenly flows from the static state, which may produce a lot of noise. When it stops, it will make a loud noise for the same reason.
19. Why does the effect of air conditioning decrease after a period of use?
Answer: Because the dust in the air of the filter screen will be dirty and blocked if it is not cleaned for a long time, it will affect the heat exchange effect of the indoor unit and reduce the cooling and heating effect of the air conditioner. Therefore, users are advised to clean the filter once every 15 days 1 time.
20. How does the outdoor unit steam or leak when heating in winter?
A: This is a normal phenomenon of air conditioning defrosting.
Because the heat pump air conditioner needs to absorb heat from the outside through the outdoor heat exchanger when heating in winter, the surface temperature of the outdoor heat exchanger is too low when working, and it will gradually frost, so the heating effect will be affected. Therefore, the air conditioner is equipped with defrosting function, which is automatically controlled by the computer board of the air conditioner. The defrosting time is about 10 minute, and the defrosting water flows down from the outdoor unit during defrosting.
2 1. Can't air supply immediately after the air conditioner is set to heat?
Answer: The air conditioner has the function of preventing cold air to prevent people from feeling uncomfortable when blowing cold air when the machine is started. Therefore, the indoor unit will not start working until the refrigerant in the heat exchanger of the indoor unit reaches a certain temperature.
22. After the negative ion air conditioner is used for a period of time, why are there black spots on the surface of the indoor unit and the wall near the indoor unit?
Answer: These black spots are precisely because negative ions have the function of adsorbing dust and bacteria in the environment. Most of the dust and bacteria adhere to the dust filter net and the ground, and a little will adhere to the metal surface, which will produce mildew spots at a certain temperature. This phenomenon is not a fault, nor is it moldy. As long as you pay attention to wiping the outer surface of the air conditioner and cleaning the dust filter, you can keep it clean.
23. When the air conditioner at home is in use, it always feels loud. Is the air conditioner abnormal?
A: When the air conditioner is running, it will make a sound due to the pressing and the operation of the fan. For different models, there are corresponding noise standards in the national standard. The noise value marked on the nameplate of air conditioner is measured in the standard laboratory environment, but the noise measured in the user's home is generally higher than the marked noise value because the superposition and testing method are different from the environmental noise, so the data measured in the user's home environment is inaccurate.
24. When the air conditioner is heating, the indoor temperature reaches the set temperature and the outdoor unit stops. Why is the indoor unit still running?
Answer: During heating operation, after the outdoor unit is shut down, the indoor unit runs in "breeze" mode, which can blow out the residual heat of the indoor unit and protect the air conditioner.
25, poor refrigeration effect:
(1) The room is too big, and the installed air conditioner does not match the room;
Ask the user whether the orientation is the top floor and whether the current and pressure of the parts are normal. If the user strongly requests to come to the door, maintenance personnel will be sent to the door to measure the temperature difference. This phenomenon is the most common and the most difficult to convince users. Now, the company has made improvements from the perspective of pre-installation inspection.
(2) Whether there is anything against the wind in front of the indoor unit and outdoor unit;
It is very important for the radiator to exchange heat with the outside air through convection after the air conditioner runs. If the air inlet and air outlet are blocked, the air flow will be short-circuited, which will lead to the decrease of heat preservation or refrigeration of the press and lead to poor heat dissipation. For example, when workers install shutters, users in residential areas are not advised to remove shutters. The company sent many maintenance personnel, but failed to solve the problem. After replacing the indoor unit, it still can't be solved, and then replacing the Panasonic unit still can't be solved. The user was convinced at this time, and finally the air conditioner was normal after the transfer.
(3) Whether the remote control setting function is in refrigeration mode and whether the temperature selection is correct;
Now many users are busy reading the instruction manual, and users will set the mode incorrectly and set the temperature incorrectly, resulting in the outdoor unit not starting the air conditioner, not cooling, or automatically turning on without blowing cold air. In fact, the temperature is set at 26 to 28 degrees, which is most suitable for the human body. When the temperature is reached, the outdoor unit will work.
(4) Air-conditioning filter will be blocked in daily use. At this point, users are advised to clean the filter.
(5) Ask whether the doors and windows are closed, how big the glass area is, and whether there are curtains.
(6) There are too many indoor heat sources, such as drinking fountains, televisions and refrigerators. Users are advised to take away the heat source.
(7) Whether there are too many people in the room, because a person needs about 120 W/ 100 kcal in a day, and the cooling effect will be affected if there are too many people.
26. The whole machine doesn't work
(1) Check whether the power switch is on-turn on the power;
(2) Check whether the plug is plugged into the socket-plug it in;
(3) Check whether the power indicator light flashes or whether the buzzer buzzes-if not, ask the user to check the power cord at home;
Yes (whether the remote controller has a battery) Yes (whether the display is normal)
(4) Check whether it can be opened manually.
No (report maintenance) No fault (install battery and observe again)-
(5) The automatic switch is in the off position;
(6) setting a timing start mode;
27. Water leakage:
(1) Inquire about the location of water leakage: indoor unit or outdoor unit. If the outdoor unit leaks water (at the valve), it is a normal phenomenon (cold and hot change condensation);
(2) Dew condensation on the wind deflector is a normal phenomenon, so users are advised to set the pendulum key. If the user extends the pipeline too long and the insulation is not good, it will lead to water leakage, so negotiate with the user to do the insulation measures;
(3) It is normal for the window machine to have running water, which can raise the position of the machine;
(4) It is normal for the external machine to leak water during defrosting in winter.
In addition to normal water leakage on the floor, abnormal water leakage will also cause losses to users' furniture, walls and floors. It's best to let the user shut down for maintenance before using it. When making an appointment for maintenance, ask about the location and quantity of water leakage. If the hole in the wall leaks, it is best for the original installer to deliver it to the door. .
28. The room smells:
(1) Ask if the room has just been renovated. When the air is not circulating, the smell is unpleasant. When it is opened, the airflow concentrates the odor in the narrow air outlet, and the user will feel the odor. It is suggested that users disassemble the air conditioner to another place for commissioning comparison;
(2) Internal plastic parts often expand with heat and contract with cold, giving off peculiar smell;
(3) The filter screen has not been cleaned for a long time, and the surface of the indoor evaporator has not been simply cleaned and maintained, which leads to mildew and deterioration, and it will give off an odor when it is turned on. Users are advised to clean the filter and remove it;
(4) Some users can adjust the position of the drain pipe through the sewer drain pipe.
29, don't stop:
(1) Ask the user whether the set temperature is too low according to the seasonal temperature, and suggest that the user set it at 24-28 degrees;
(2) Whether the doors and windows are closed to maintain indoor air tightness.
(3) Some air-conditioning display screens have temperature display, and there is an error between the indoor temperature displayed on the display screen and the temperature around the air-conditioning probe.
(4) The filter screen is dirty, which leads to poor circulation and poor refrigeration effect, and the set temperature cannot be reached without stopping the machine;

3 1. Abnormal sound occurs when the air conditioner is running.
(1) When cooling or heating, the plastic parts make abnormal noise when the evaporator expands with heat and contracts with cold, which is the most difficult to convince users. Buying different brands of air conditioners makes different noises.
(2) The sound of running water in the internal machine is normal for Freon refrigeration to flow in the pipeline; This sound is a normal sound generated by refrigerant flow, not a machine failure.
(3) The sound made by the relay during operation is normal;
(4) Because the structural components of the new machine are tightly assembled, the friction sound generated by the rotation of the air deflector is normal, and users can observe whether there is such a sound after using it for a period of time.
32. The remote control cannot be turned on.
(1) Whether the transmitter and receiver are facing each other;
(2) Whether the remote control is displayed, check the battery capacity (replace the new battery, pay attention to the positive and negative poles);
(3) Whether there are interference sources such as sunlight or energy-saving lamps, blocking sunlight or turning off lights;
(4) Press Manual to start the machine, as above.
33. Too much air conditioning (too cold)
(1) Ask whether the set temperature is too low, and set an appropriate temperature (26-28 degrees cold, 0/8-22 degrees warm);
(2) Whether the temperature regulating switch is in a continuous position;
(3) Whether it is in automatic operation.
