What are the toughest topics to talk about these days? That must be the weather
Controlled by sub-tropical pressure or prolonged stabilization, weather has improved in recent days and temperatures are “higher”。
How high? So far, chengdu weather stations have launched high-temperature red warning signals on six consecutive days, all of which have reached record high temperatures at 12 national meteorological stations。
In recent days, a number of citizens have reported to red star news that the air conditioner in their home this year is still very hot. Or is there not enough fluorine
The air conditioner's not cool. The maintenance man's busy
"neighbors, do you know anyone who fixes air conditioning? Most air conditioners don't feel cool..." at 9 a. M. On 16 august, mr. Wang, who lives in chenghua district, sought help from his neighbours in the community, even opening the air conditioner in the morning because of the heat of the day。
Mr. Wang's call for help prompted his neighbour “to nod in large areas”, “yes, me too.” “my family's as well ...”, because, without cooling, mr. Wang's neighbours thought that the air conditioner was broken or fluorinated, and even invited the maintenance master to the door, but were eventually told that the outdoor temperature was too high, which led to the air conditioner “sucking”。
So, does the air conditioner really stop because it's too hot
In recent days, some citizens have received feedback on the issue of air conditioners “unrefrigerated or less irritated than in the previous days” through messages such as social media. According to kmt+ air conditioner maintenance engineers, this was mostly due to high outdoor temperatures。
Recently, chengdu weather has become hot, with temperatures in some districts (municipalities) exceeding 40 degrees, and temperatures on the ground are above 60 degrees c due to long periods of roasting. When the local surface temperature exceeded 60°c, red star journalists were told by the east that the outer air conditioner shell was also very hot and that the air conditioner compressor would initiate “overheating protection” because of the high working temperature to the critical point of its design operation. He's been in business for over a decade, and this has never happened before。
When the ac “overheating protection” is activated, the cooling effect becomes worse and even external opportunities cease to function, “this is why you often reflect the natural internal wind that does not blow.” he explained that this was due to external causes, that it was normal and that it was not necessary for the air conditioner to fail。
What about overheat protection in air conditioning
If the air conditioner is “overheated”, the citizen may change the air conditioner temperature to about 26°c or temporarily turn off the air conditioner for a period of time to give a rest to the continuous operating air conditioner. In addition, air conditioners (acs) have a normal outdoor temperature difference of about 15°c, “in order for compressors to be activated quickly, they can properly water the temperature in the out-of-air air conditioners, or install a sunshield, while citizens must be careful to install the out-of-air air conditioners where they are cool, heat-dispersed and ventilated”。
In addition to excessive external temperatures, what are the reasons for the ac “deficit”
In addition to excessive external temperatures, the non-refrigeration or poor cooling of air conditioners is due to inadequate maintenance。
It has been described that air conditioners need to be regularly cleaned both inside and outside, otherwise problems such as poor cooling may arise. “the insider recommends a 15-day clean-up, if not less than one year.” external aircraft, in turn, require cleaning by professionals, the cycle of which is determined by the environment in which the aircraft is located。
How do you judge whether the air conditioner “deficit” is caused by excessive outdoor temperatures or a fluorine shortage
It was reported to the press that citizens had to debug the air conditioners in the morning or at night, since the outdoor temperatures in both periods were generally the lowest, and if the air conditioners were functioning at that time, the reasons for the fluorine deficiency of the air conditioners could largely be excluded。
If two time-frames of air-conditioning remain unrefrigerated, consideration will be given to fluorine deficiencies and other causes, requiring specialized maintenance staff to visit the house。
In addition to environmental factors and fluorine shortages, recent hot weather conditions, high electricity consumption, stress in electricity supply and unstable voltage can also lead to non-working external and normal internal operation。
How do citizens judge whether air conditioners are fluorinated
The simplest way to observe an air conditioner in the air conditioner and an outer copper pipe connection is to see the external air conditioner, “if the frost is fluorine-deficit, no frost, but water drops are not fluorine”
What are the common irregularities in the use of air conditioning
No filtering。
There are three advantages to cleaning the filters, which can initially maximize the desired cooling effect, which can deteriorate if it is not washed over the long term。
Second, it's more expensive not to clean filters, and the cost of electricity goes up。
Finally, there is a great deal of bacteria and bacteria in the filters, and when air conditioners operate, these fine and bacteria can then spread indoors, endangering the health of individuals. The cleaning of the interior filter is really simple, and adults can operate on the air conditioning instructions。
2. Frequent adjustments to air conditioning operating patterns
When the remote control is in a “refrigeration” mode, the user can move up and down, but not frequently from the “refrigeration” mode to other modes, such as “except wet” “heat-making”, which can also lead to the decommissioning and non-refrigeration of air conditioners。
What is the most efficient and simple maintenance method for air conditioning
Clean the filters, with the conditions to do it。

The temperature must be reasonable
The setting of indoor air-conditioning temperatures at 26°c-28°c is more appropriate in the summer, and many households often set air-conditioning temperatures at 23°c or even lower, and are highly vulnerable to “air-conditioning syndrome” in such environments for long periods of time。
The wind is cooler up
The cold air goes down, the hot air goes up, and when cooling, the air-conditioning wind goes up, so the cold air circulates from the top to the bottom, and the energy is cool。
Use of time and sleep functions in due course
The sleep mode allows air conditioners to raise the temperature according to ambient temperature, with the effect of saving electricity。
Regular cleaning of filters and heat spread snippets
Whether attached or desktop air conditioners are used, they need to be cleaned up once a year. The cleaning cycle is also shortened if the air conditioner is in high-smoking condition。
No frequent switch air conditioning
Reduction in the number of re-starts of compressors and more electricity-efficient continuous operation。
