Why does the air conditioner smell of vinegar?

Unless someone deliberately throws vinegar on the air conditioner.

Air conditioner, i.e. air conditioner. It refers to the equipment that uses artificial means to regulate and control the temperature, humidity, flow rate and other parameters of the ambient air in the building or structure.

Generally, it includes cold source heat source equipment, cold and hot medium transmission and distribution system, terminal device and other major parts and other auxiliary equipment. It mainly includes refrigeration hosts, pumps, fans and piping systems. The terminal device is responsible for using the cold and heat from the transmission and distribution to specifically treat the air state and make the air parameters of the target environment meet certain requirements.

Air conditioners are divided into single cooling air conditioners and cold and warm air conditioners, the working principle is the same, and most of the refrigerants used in air conditioners before were freon. The characteristic of Freon is that when it changes from a gaseous state to a liquid state, a large amount of heat is released.

When the liquid state changes from a gaseous state, it absorbs a large amount of heat. (i.e., first absorbing heat and gasification and then liquefiing and heat release) air conditioners are designed according to this principle.

The compressor compresses the gaseous refrigerant into a gaseous refrigerant with high temperature and high pressure, and then sends it to the condenser (outdoor unit) to dissipate heat and becomes a liquid refrigerant at room temperature and high pressure, so the outdoor unit blows hot air.

Then to the capillary, into the evaporator (indoor unit), because the refrigerant from the capillary to the evaporator after the space suddenly increases, the pressure decreases, the liquid refrigerant will vaporize, into a gaseous low-temperature refrigerant, thereby absorbing a lot of heat, the evaporator will become cold, the fan of the indoor unit will blow the indoor air from the evaporator, so the indoor unit blows out of the cold air; When the water vapor in the air meets the cold evaporator, it will condense into water droplets and flow out down the water pipe, which is why the air conditioner will produce water.

There is a component called the four-way valve during heating, so that the flow direction of the refrigerant in the condenser and evaporator is opposite to that of refrigeration, so when heating, the outdoor air blows cold air, and the indoor unit blows hot air.

In fact, it is the principle of expelling heat during liquefaction (changing from a gas to a liquid state) and absorbing heat during vaporization (from a liquid to a gas) that I learned in junior high school physics.

How the eco-friendly air conditioner works:

The water in the water tank is pumped out uninterruptedly with a circulating water pump, and evenly sprayed on the evaporation filter layer through the water distribution system, the outdoor hot air enters the evaporative cooling medium, and the heat exchange is fully carried out with the water in the evaporative cooling medium (honeycomb filter layer of special material, so that the cooling effect is more ideal, Sweden's high-tech patented products), and the cool and clean air cooled by water evaporation and heat absorption is pressurized into the room by the low-noise fan, so that the indoor hot air is discharged to the outside, so as to achieve the purpose of indoor cooling.

The reasons for the peculiar smell of the air conditioner: 1. Because the air conditioner is refrigerated and heated, in many cases, there will be moisture inside the indoor unit, so when the air conditioner is turned off, the air conditioner without dry and mildew prevention function will be shut down immediately, so that the internal moisture has always existed, and mold will be produced in the long run, and the musty smell will naturally occur. 2. After years of use, the indoor filter and copper sheet will squeeze a certain amount of dust, so that after accumulating to a certain amount, a certain odor will be generated, and with the air conditioner turned on, the air conditioning outlet odor will drift into the air.

Solution: 1. When cleaning the filter screen, first cut off the power supply, then open the panel and take out the filter screen. 2. It should also be checked whether the drainage pipe is unblocked, and it should be repaired or replaced in time.

3. After installing the filter, turn on the power and wait for 3 to 5 minutes, set the remote control in refrigeration mode, set the temperature to the lowest, and then turn on the machine. After the air conditioner is running, set the wind speed switch of the remote control to run in different gears to observe whether there is abnormal noise in the internal unit.

After the main air conditioner is refrigerated and heated, in many cases, there will be moisture inside the indoor unit, so when the air conditioner is turned off, the air conditioner without dry and mildew prevention function will be shut down immediately, so that the internal moisture has always existed, and mold will be produced in the long run, and the musty smell will naturally occur.

1) Every time you use the car air conditioner, don't be in a hurry to turn off the engine, and idle it for 3-5 minutes to increase the temperature of the air conditioning pipeline and eliminate the temperature difference with the outside world, (2) Long-term rainy weather has a great impact on the air conditioner. It is best to open the air conditioning ducts after natural wind or warm air drying to avoid mildew on sunny days. (3) If the external environment is very bad, it is best not to turn on the external circulation air conditioning system of the car.

4) Reduce the food in the car, (5) Pay attention to the use of perfume in the car, it is better not to use acidic perfume, this is because acidic perfume is prone to mildew in the evaporation tank.

Hello dear<> the sour smell of acetate blown by the air conditioner may be caused by the following conditions:1There is a problem with the air conditioner filter:

When too much dust or other contaminants accumulate on the air conditioner filter, it will smell like acetic acid, and the air conditioner filter should be cleaned or replaced. 2.There is a problem with the internal parts of the air conditioner:

If the internal parts of the air conditioner are faulty or contaminated, odors can also occur. Odors from components such as air conditioners, compressors, evaporators, etc., are a common problem. 3.

Pollution in air-conditioning ducts: Air-conditioning ducts absorb a lot of dust, bacteria, soot, mold and other pollutants over the years, and if the pipes are not cleaned regularly, they will emit odors. 4.

Poor air quality in the room: If the indoor air quality itself is poor, it will cause the air conditioner to blow out the vinegar sour smell. Indoor air quality can be improved by strengthening indoor ventilation, maintaining hygiene, and other measures.

If you determine that the problem is caused by the Attendant Activation, it is recommended that you contact a professional maintenance personnel for inspection and repair. At the same time, it is also very important to keep the room clean frequently and clean the air conditioner filter regularly to avoid air pollution.

Summary. First, the air conditioner has not been cleaned for a long time, resulting in the internal components of the air conditioner becoming a breeding ground for bacteria to breed and spread.

In this case, the sour smell of the air conditioner is in these bacterial metabolites, because it contains sour substances. The most direct solution is to clean and disinfect the air conditioner regularly to effectively inhibit the growth of bacteria.

The second situation generally occurs in the refrigeration mode of the inverter air conditioner. When the room temperature reaches the set temperature of the air conditioner, the outdoor unit begins to stop operating, and the indoor unit Bihui will be in air supply mode, which will send out a sour smell at this time, which may be caused by the spring album hydrophilic aluminum foil coating material used in the heat exchanger of the air conditioner.

The third type: the cause of the sour smell may also be that the condensate generated during the refrigeration in the air conditioner is not drained clean, which leads to a peculiar smell after a long time. In this case, it is recommended to turn on the dehumidifying function to let the air conditioner drain the condensate as much as possible. Then see if the water pipe in the row wheel section is lower than the pipe mouth.
