Why does the hotel air conditioner smell like food?

This is a damp smell. It'll be all right in a minute.

This air conditioner has not been cleaned for a long time, and it is very dirty, which is caused by excessive mold reproduction.

1 If the air conditioner runs for a long time, a certain amount of dust will be squeezed inside the filter screen and copper sheet of the air conditioner, and the dust will also accumulate between the fins of the heat exchanger, which will cause blockage after accumulating to a certain amount; Produce a certain smell, and with the opening of the air conditioner, the smell emitted by the air conditioner will drift into the air.

Because the air conditioner is hot after refrigeration, there will be moisture inside the indoor unit in many cases, 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 mold will be produced after a long time, which will naturally produce a musty smell.

3 Air conditioners that have not been used for a long time will also produce odor when they are started, because the condensed water on the heat exchange coil, fins and their peripheral components slowly evaporates, forming a high temperature condition around the coil suitable for microbial reproduction, and a large amount of gas generated during microbial reproduction will be released under the drive of the air conditioning system and become the source of odor.

4 The inefficient filtration system at the air supply outlet of hotel rooms, although the interior decoration is good, filtered fresh air and air conditioning supply, 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. A lot of dust in these places not only carries microorganisms, but also provides indispensable nutritional conditions for the reproduction of microorganisms, which leads to the odor of air conditioners.

If you often smoke, spray perfume and make up in an air-conditioned room, the air conditioner in the room will circulate through the air conditioner evaporator (indoor unit) for a long time and be adsorbed on the evaporator or filter screen. After a long time, the air conditioner will smell strange when it is first turned on, so the air-conditioned room should be kept clean.
