The ac axis is a taboo? Thanks to master, i saved thousands of dollars
Just in may, the temperature went up like a wild horse and went down 35 degrees. The weekends are home, heat waves are unbearable and the air conditioning is driven to a strong mode and even intended to operate 24 hours a day. However, the elders of the family were concerned and kept saying, "how can the compressor stand this machine running for 10 hours? What if it burns?" there is a question as to whether this air conditioner should be “co-axis” or “breathing”? With this anxiety in mind, a senior air conditioner maintenance specialist was specially consulted, and the answer was a big drop in the eye: the wrong way to open the machine was the one that caused the air conditioner to end earlier。
I. Closure is not supplemental, and the clush is worthing
Modern air conditioners are fully capable of running on a 24-hour basis, based on engineering principles. With reference to the central air-conditioning systems of hotels, malls and data centres, they tend to last several months in the summer and remain stable. This is thanks to a sophisticated internal temperature control mechanism: when room temperature touches the set threshold, the compression opportunity automatically stops or drops, retaining only fans to maintain the air cycle; the compressor intervenes again after the temperature rises. This is much more resilient than a long-runer, jogging at even speed than intermittent sprinting。
However, continuous operation presupposes a good dissipation environment. Many family air conditioners strike not because of machine quality deficiencies, but because of poor conditions of use. Most typically, it's "dry can". In pursuit of extreme thermogenic effects, doors and windows are closed without any gaps, resulting in the inability of indoor air to convectate and the difficulty of dispersing heat from external aircraft. Under this condition, the air conditioner is like a front load of a mask, which can easily trigger an overheating protection device and force a stop。
Two, three destruction habits, accelerating the end of ac life
In addition to poor ventilation, the experts noted, inter alia, that three common operating habits in the summer were tantamount to a “destructive blow” to air conditioning。
First of all, the filter is dusted into “twilight”, which is still being used by force. A large number of users have never cleaned the filters since their installation, and dust and fur are quickly blocked when high frequency is used in the summer. This layer of “barriers” hinders cold wind output, resulting in a sudden drop in the temperature of the interior, which forces the outer aircraft to operate at full capacity. This not only increases electricity consumption significantly, but also makes it easier to burn wires because compressors overheat. According to statistics, 80 per cent of the cases reported during the summer were reported as having malfunctions due to network congestion。
Second, the voltage remains unstable and is still in force. The summer season coincides with a peak in electricity use, with high voltage fluctuations in the old and small areas. Air conditioning is extremely sensitive to voltage, which is unstable and leads to frequent compressor “twitching” and high current fluctuations. The internal circuit boards are easily punctured and irreversibly damaged at this point in time when the axis is forced to turn。
Besides, it's hot out there
And lack of protection. Many out-of-air air conditioners are installed on the west tan wall, and direct solar radiation brings their temperature closer to 50 degrees at 23 p. M. At this point in time, extra heat discharges are required in high-temperature environments and are undoubtedly “fire oil”. Even a high-end machine type cannot withstand a 24-hour cycle of heavy pressure under such extreme conditions。
3. Frequent switch-off is the hidden "invisible killer"
For 'short time out'
In a dispute over whether to turn off air conditioning, the experts made clear recommendations: if the time of departure is less than one or two hours, do not turn off the air conditioner. There is a general public perception that “human walkers” can save electricity, which is a fatal error. The air conditioner is activated at a time when the compressor requires five to seven times the current required for normal operation. Frequent switches are tantamount to allowing compressors to suffer repeated electric shocks, such as frequent car outbursts and fires, which do not save fuel and cause severe motor damage. The data show that the damage to compressors caused by frequent stoppages accounts for the largest proportion of the total maintenance. Therefore, short trips to maintain the status quo ante are more energy-efficient and better machine protection than restart。
Iv. Guides for scientific use to make air conditioning more durable and human comfortable
In the face of the impending continuing high temperatures, mastery of scientific methods of use is crucial. The experts provided four practical recommendations for this purpose:
First, the temperature differential is reasonably set. Controlling temperatures between 26 and 28 degrees not only meets human comfort needs, but also provides external breathing opportunities. Variable-frequency air conditioners can operate in this zone at low frequencies, while the fixed-frequency air conditioners can stop at the right time and achieve a genuine combination of effort。
Second, implement physical cooling. When the air conditioner is activated during the day, it is important to close the curtains and to block the indoor warming caused by direct sunlight. This will significantly reduce the air conditioner cooling burden and improve refrigeration efficiency。
Third, assistive cycle equipment. For rooms with larger space or more closed space, it is recommended to be used in combination with air cycle fans. The fans evenly stir the cooling air into the house to help air conditioners quickly reach set temperatures and drive compressors into low-capacity conditions。
Fourth, regular cleaning and maintenance. Cleaning of filters at least once a month is the least costly and most efficient means of maintenance. Dismantling filters and drying them back will ensure smooth air conditioning while avoiding bacteria。
Having heard the expert's professional analysis, the previous doubts faded. Air conditioning is not a porcelain valor, but it is only necessary to adapt to its working characteristics and provide a suitable operating environment, and it is well equipped to perform long-term refrigeration tasks. May is only a prelude to the heat, and the high-temperature test of the future will continue. Instead of fixing the time of the switch, we should clean the filters, set the temperature, and give air conditioning a cool summer space. I wonder how long your air conditioning usually works? Has there been a sudden strike? Welcome to sharing your use experience。
