What happened to Mai Rui Bao's air conditioner heater? Causes of air conditioning odor.
1
Reason 1. After the air conditioner has been used for many years, a certain amount of dust will be squeezed inside the indoor filter screen and copper sheet, which will produce a certain smell after accumulating to a certain amount. As the air conditioner is turned on, the odor emitted by the air conditioner will drift into the air.
2
Reason 2: In many cases, after the air conditioner is cooled and heated, there will be moisture inside the indoor unit, so when the air conditioner is turned off, the air conditioner without drying and mildew-proof function will stop immediately, so the moisture inside will always exist, and it will produce mold for a long time, which will naturally produce a musty smell.
three
Reason 3: The system has not been running for a long time, and the fins of the heat exchanger are almost full.
four
Reason 4: Some inefficient filtration systems at the end of air supply, such as computer rooms and hotel rooms, are well decorated, and fresh air and air conditioning supply are filtered, but dust can still be found near some indoor air supply outlets and on the surface of window sills, and a layer of dust is also attached to the surface of internal components.

Reason 5: After the air conditioning system is started, the indoor bacterial concentration and odor increase instead. This is because the condensed water on the heat exchange coil, fins and their peripheral components slowly evaporates, forming a high humidity (and high temperature) condition around the coil, which becomes an environment suitable for microbial reproduction. A large number of gases produced in the process of reproduction are suddenly released by the system drive and become the source of odor. It is believed that a large amount of dust accumulated in these places brought by fresh air not only carries microorganisms, but also provides indispensable nutritional conditions for microbial reproduction.
Turn on the air conditioner, turn on the heating, and it smells like burning skin. What happened? If the air outlet is in good condition and the burnt smell does not belong to the smell of plastic rubber, it generally doesn't matter, and it will get better after a while; If it smells like burning electrical appliances, it needs to be opened for inspection.
Air conditioning heating is to use the principle of heat pump to move outdoor heat energy indoors. Some air conditioners are supplemented by electric heating.
When air conditioning is used for heating, the temperature of heating devices is relatively high, and the surfaces of these heating devices will inevitably be contaminated with dust, wool and even some bugs, which will produce a burnt smell when heated. Especially for air conditioners that have not been used for a long time in summer, due to the internal humidity during refrigeration, dust can easily form slurry and attach to components, which will have a strong smell when heating for the first time that year. After a period of time, the volatile substances in it will completely evaporate, so it will not continue to produce fragrance.
If the air conditioner doesn't blow for a few minutes after starting, or it smells like burning electrical materials, it may be that the air conditioner is faulty, so please ask a professional to repair it.
It is best to clean the inside of the air conditioner once or twice a year. When it is not used for a long time, it is best to cover the top with cloth or paper to reduce the entry of dust.
As soon as the air conditioner is turned on, there is a strong earthy smell. Some people know how to solve it. Hello, cleaning the water tank of the air-conditioning heater and disinfecting the air-conditioning duct are caused by the growth of bacteria in the duct.
Solution: The air conditioner turns on the warm air. What's the problem with not being hot? Is the thermostat on? Does the thermostat work? Whether the heater motor works. Whether the cooling water pipe leaks.
Gree air conditioner turns on 16 degree refrigeration, but it is warm air. What happened? 1: The refrigeration internal unit does not supply power to the four-way valve of the external unit (if the power supply indicates that there is a problem with the motherboard of the internal unit), just unplug the four-way coil wire.
2. The coil of the four-way valve has no electricity, indicating that the internal machine is normal, the four-way valve has not been reset, and it is still in a heating state. You can tap the capillary on the four-way valve with a small piece of wood (this is usually the problem). When the faucet fails, you can only change it.
Car air conditioners smell earthy. This car has a ventilation system. The air inlet is generally under the windshield, and the air outlet is hidden and generally covered by the rear bumper. When a normal car is running, the outside air enters the air duct through the air inlet, that is, the air duct of the air conditioning system, and enters the car. The air conditioning system has an external circulation switch to control this.
If the air conditioner is turned on, it smells of dust, which may be caused by the bad air outside. Just turn off the external circulation. But it may also be that the air duct of the air conditioner has not been cleaned for many years, and the inside is full of dust, so it needs to be cleaned at this time. Some cars have installed pollen filters on the passage where the outside air enters the car, which can prevent dust from entering, but after a long time, the pollen filters should be replaced, or at least taken out, washed with water and put back.
Ask for help. Recently, warm air smells of dust. It is recommended to check the air-conditioned space for the smell of garbage. It is possible that a lot of flying dust has accumulated in the space. It can be cleaned or replaced, and then decided after inspection.
Why did the heating and air conditioning in Weizi start? Why does the compressor rotate when the heated air is turned on?
Opening mode of cold air conditioner:
1: Turn on the fan switch. 1.2.3.4. Any number of gears can be opened.
2: Turn on an A/C switch under the fan switch, and press it once to display the prompt light.
3: Switch between hot and cold and hit the blue bottom.
Just turn on the fan of the hot air conditioner and turn the hot and cold switch to the red side. Don't turn on the air conditioner switch.
The air conditioner turns on the cold air and the warm air, so the external machine turns to the internal machine. What happened? The external machine does not turn (compressor), that is to say, turning for a while at first is the reason for protection and inspection.
