You ready for air conditioning
Attention
A few months of air conditioning
It's probably hidden
Before you turn on the air conditioner
We must do this first
Air conditioning. It's far more dirty than i thought
If air conditioners are not cleaned for long periods of time, the filters tend to accumulate large quantities of small particles of dust, dust mites, fungus and micro-organisms such as bacteria and viruses。
Previously, the china society for environmental sciences (cset) indoor environment and health division conducted home-based research on domestic air conditioning in the cities of beijing and shenzhen。
The results showed that 88 per cent of the hac distillation tablets exceeded the total number of bacteria on the table by an average of about 40 times the standard (the standard is 100 bacteria per square centimetre); with the exception of bacteria, 84 per cent of the hac distillation tablets exceeded the total number of fungus on the table。
Keep an eye on legionella hiding air conditioners
Particular attention needs to be paid to the fact that air conditioners are chronically insulated from cleaning, and that their dispersive films and cooling water systems produce a lethal strain — the legionary bacteria. When air conditioners send wind, legionella is distributed into the air in the form of aerosols and is susceptible to inhalation-induced infections。
How dangerous is it that air conditioners are not cleaned
It's causing lung infections
In the event of infection with the legion, it may cause the legion's fungal pneumonia. Early symptoms, such as fever, cough, inactivity, etc., are similar to influenza, common pneumonia, and can be easily ignored or misdiagnosed, but the conditions can progress rapidly, with older and middle-aged people, people suffering from basic diseases and people with low immune capacity developing into acute pneumonia, respiratory failure and even causing multi-organ failure and higher risk of death。
Uncleaned vehicle-borne air conditioners are equally dangerous. In june 2024, mr. Hunanjo was travelling for long periods of time using uncleaned air conditioners to identify the legion of the corps's pneumococcal pneumonia (charted as pre- and post-pulmonary ct images)。
Skin disease
Without long-term cleaning, large quantities of dust mites within air conditioners blow to the human body with wind, stimulating dry and fragile skin tissues and causing allergies or rashes。
Inducing respiratory diseases
If the air conditioner is not cleaned for a long period of time, the internal bacteria that breed may come out of the wind and may lead to bacterial infections, dizziness, lack of strength, pain in the throat, cold, nasal inflammation and allergic respiratory diseases。
Home air conditioning clean-up full plan
If a central air conditioner is used in the home, it is recommended that the windpipes and evaporation units be cleaned and disinfected by professionals every year before they are opened; if the normal home air conditioner is self-cleaned, remember these steps. Zenium
Turn off the power: the air conditioner plug must be removed before cleaning up in order to prevent electrical exposure。
Cleaning of air-conditioning filters: remove filters, wash back (dud) with water and wash lightly, and then dry it naturally in the shade。
Cleaning evaporaters: after the filter is removed, the evaporation dispenser is seen, and home air-conditioning washing agents are selected for spray, but do not spray to the evaporation unit outside to avoid short circuits after opening; dry filters and panels are returned after spraying and about 15 minutes are still available; air-conditioning is activated for 20 to 30 minutes to get sewage out of the drain。
The hot season is coming
Don't forget to wash the air conditioner before it's activated
You need to use the air, not to be greedy
As soon as the air conditioner is turned on and kept on
Which one's more expensive
To save electricity, people turn it on many times a day, it's hot, it's cold and it's fast
According to the senior engineer, li jinxiang, director of science and technology, china institute of refrigeration, frequent switch air conditioners are more expensive than electricity。
Energy consumption during the start-up phase of air conditioning is high. The number of restarts has increased, and the total energy consumption exceeds the energy consumption that the ac has been running. Moreover, the longer air conditioners work, the clearer the comparison。
In addition, frequent switch air conditioners can cause compressor damage, resulting in a shorter useful life. In order to save electricity from air conditioning, it would be more efficient to minimize the heat exchange in and out of the room, complete power cuts when air conditioning is not used, rational use of sleep patterns and the use of variable frequency air conditioning。
In summer, with air conditioning, there's a power-saving secret
It was stated that air conditioners can also be cooled and used more economically. So, does dehumidisation really save electricity? How can air conditioners be used with cooler and less electricity
Choi choi, an engineer at the faculty of physics and electronics of the university of huatung, shared the departmental secrets of air conditioning during the summer:
The three-volt, hot and damp in the south can open up the dehumidation mode of air conditioners and ensure an indoor humidity of 45% to 65%, enhance the comfort of the body and contribute to human health. If the initial temperature is higher in the room, the cooling mode can be opened and replaced by a wetting mode after the temperature of the room has decreased, which will save electricity and achieve dehumid cooling。
Most cities in the north are hot but not humid in the summer and should choose a refrigeration model. Especially in high temperatures, such as those of close to 40°c, when the dehumidisation mode is activated, instead of saving electricity, it increases the amount of electricity consumed, and slow cooling affects comfort。
I want a healthy air conditioner
The chief of the respiratory and critical medical department at anzhen hospital in beijing, dr. Manzhu, said that to blow air conditioning in a healthy manner, note these eight points:
Regular cleaning of air conditioners
Air conditioners that are not used for long periods of time are best cleaned up in time before they are used, and it is recommended that filters of air conditioners be cleaned every half month in order to obtain clean air, and that long-term filtering of the web cover gather dust, leading to ingestion and ventilation, reduced air conditioning performance and increased power consumption。
2. Avoiding sudden cold and heat
Our body has limited adaptive capacity, such as sudden access to air conditioners from very hot environments, or sudden movement from air conditioning to very hot environments, where the body is prone to immunological disorders and low immune functions。
3. Maintenance of indoor humidity
Proper humidity is useful for the preservation of immune functions such as respiratory mucous membranes, skin, etc., so that some indoor humidity is maintained to avoid cold and dry. Water can be filled with proper drinking water, or a pot of water can be placed below the air-conditioning vent to improve humidity, with an appropriate temperature control of 40 to 60 per cent in the room。
4. Unsuitable temperatures
Air-conditioning temperatures should not be set too low, indoor and outdoor temperature differentials should not be too high. Over and above the general assembly increases the burden on the body-temperature-regulating hub, they can also easily cause discomfort such as dizziness, dry skin, dry tongue, etc., and they also consume electricity, usually at the most suitable temperature of 26°c ~ 28°c。
5. Periodic open window ventilation
Air conditioning can lead to air inactivity and a decline in air quality, which can cause respiratory disorders such as nose plugs, throat drying and sneezing. Therefore, it is important to keep in mind that there is a constant change of air, and it is recommended that windows be opened for about two to three hours, each for about 10 to 15 minutes, to ensure that indoor air is fresh。
6. Avoid blowing up the body
To avoid cold winds blowing through the body, especially where the head, knee, small abdomen, waist, etc. Are more sensitive to the temperature. If the head is blown directly to the neck, the decrease in the temperature of the scalp is likely to cause cerebrovascular constriction and, in the case of older persons with cardiovascular diseases, a stroke can be induced in serious cases。
Winds are cooler up
When cooling with the ac, it is advisable to turn the ac wind up and allow the cold air to circulate from top to bottom. When heat is produced, the air conditioner wind is directed downward. In general, the cold air moves down, while the hot air reverses, thus making full use of its own physical properties and natural exchange。
8. Old people need air conditioning in time
Older people may experience “hidden summer heat” when “not feeling hot”. As the age rises, the sensitivity of the skin temperature sensor for the elderly is lowered, and the feeling of external temperature and humidity becomes less apparent. So even with high room temperature, they may not feel very hot。
Long-term exposure to high-temperature, wet, unventilated indoor environments is prone to dehydration, heat dissipation, electrolytic disorders in the body and therefore to heat. Therefore, air conditioning should be operated in a timely manner and proper indoor ventilation should be maintained。
