Analysis of common problems in slow heating of air conditioning
With the end of rainfall nationwide, the first round of high temperature weather is sweeping across the country. According to data released by the Central Meteorological Observatory, the high temperature was nearly a month earlier than usual. Following May 15th, some provinces and cities in East China, Chongqing, and central and northern Hainan experienced high temperatures above 35 ° C. On the 16th, Jianghan and Eastern South China also joined High temperature battlefield.
"The weather has been getting hotter recently, but it's still like being in a steamer when the air conditioner is turned on." With the gradual arrival of summer, the air conditioner has become an indispensable "summer artifact" for many families, but Ms. Li, who lives in Nanjing, has encountered problem. According to her description, the air conditioner at home has a slow cooling speed, and it often takes a long time to experience a hint of coolness after booting. In fact, the slow temperature increase of air conditioners has been a problem that has plagued users for many years. Its emergence is affected by many factors, and it is necessary to take the right medicine to solve the problem from the root cause.
When the starting capacitor of the compressor is aging due to high temperature, frequent voltage fluctuations and other reasons, it is only possible to restart it under repeated impact of voltage and current for a period of time after the power is turned on. In the process of restarting, the indoor unit air outlet is not cold, and the temperature of the indoor unit outlet air will not decrease until the compressor is started. In this case, a professional air-conditioning technician needs to be brought in for repair and replacement.
Shackles of traditional inverter drive technologyThe traditional variable frequency drive technology used in ordinary air conditioners is limited by technology. The high-frequency operation current ripple of the compressor is large, which is easy to achieve the compressor demagnetization current protection. You can only choose to reduce the high-frequency operation frequency to ensure the reliability of the compressor operation; Out-of-step and abnormal shutdown during compressor start-up usually use a lower rate of frequency increase, resulting in slower temperature changes and poorer experience.
The indoor unit evaporator is too dirty, the filter is too dustyIf the return air filter of the air conditioner indoor unit is too dirty, when the air conditioner is running in the cooling mode, although the air conditioner maintains normal cooling, the air volume of the indoor unit becomes smaller due to the dust blocking, resulting in a slower temperature drop in the room. Generally speaking, the filter is the most frequently polluted part that people clean and the easiest to clean. The old air conditioners in the home must be cleaned at least twice a year.
The number of air conditioners does not match the indoor space, which will not only affect the cooling speed, but also affect the cooling effect. In the long run, the life of the air conditioner will also be affected. According to a large number of tests and the human body's perception of external temperature, one air conditioner is suitable for rooms of about 12 square meters, two air conditioners are suitable for rooms of about 25 square meters, 2.5 air conditioners are suitable for rooms of about 40 square meters, and 3 air conditioners It is suitable for rooms of about 50 square meters, and 4 air conditioners are suitable for rooms of about 70 square meters.
In addition to the above solutions, it is also a good choice to replace the old air conditioners in the house at the right time. On May 23, the commander L.ONE air conditioner made its debut on the official social interaction platform of Haier Group. It is reported that this air conditioner is equipped with frequency hopping drive technology, which accurately hits the pain point of the current air conditioner's slow temperature and speed increase. After testing by the National Daily Electrical Appliance Quality Supervision and Testing Center, after the commander air conditioner starts normal airflow, the maximum temperature change rate of the airflow can exceed 10 seconds and 10 degrees. This is the first time in the industry and has raised the standard of user use in the entire industry.
Many times, the cause of various problems with air conditioners is the inattention in later use. As a whole system of household air conditioners, in addition to the early design and installation, regular inspection and maintenance in the later period is particularly important. Choosing the right air-conditioning products and carrying out regular inspection and maintenance will not only ensure the efficient and stable operation of household air conditioners, but also extend their service life.
Gear Sensor has been widely used in the automotive and industrial field, which is important to the measurement of velocity, angel, angular velocity, direction of rotation.
