In today's consumption upgrading, accidents caused by household appliances that exceed the age limit are frequent, which also reminds us that we must pay attention to the safety of old household appliances and timely replacement. Especially in the hot summer, air conditioning has become a savior for many people, but the safety hazards of products that exceed the age can not be ignored. How to effectively avoid accidents, you might as well follow Shanghai Home Grid to take a look.
First of all, there are multiple risks in air conditioners that have exceeded their service life, because air conditioners are large-load electrical equipment and have certain requirements for the circuit system. Generally, the service life of air conditioners is 8 to 10 years, beyond which air conditioners will not only pollute indoor air, but also may cause electricity consumption to skyrocket, noise to become louder, and even fire due to aging wiring. In particular, the air conditioner unit hanging outdoors is also easy to fall after the aging of fixed objects, bringing unpredictable dangers. In addition, due to backward technology, old air conditioners have low energy efficiency, and the electricity consumed is much greater than that of high-energy-efficiency air conditioners.
But it's not enough to simply understand the safety of old air conditioners, but also to be cautious about second-hand air conditioners on the market.
In this regard, the advice given by Shanghai Home Grid is not to buy second-hand air conditioners. Because many unscrupulous merchants bleached the old air conditioner with chemical cleaners, making it look like a new machine, but in fact, the body material cannot be changed. There are many hidden dangers in these "refurbished" second-hand air conditioners, such as air ducts, wind wheels and evaporators that have not been professionally disassembled and cleaned, which are easy to breed pathogenic bacteria. In the refurbishment process, the various cleaning agents and yellowing agents used will also bring secondary pollution.
In short, in order to use the air conditioner safely, it is recommended to find professional maintenance personnel for maintenance and repair in time after the air conditioner fails, and replace the old air conditioner regularly; Try not to buy and use second-hand air conditioners; Maintain the air conditioner to avoid potential safety hazards; Avoid frequent switching on and off in a short period of time to increase the service life of the air conditioner; Regularly clean the filter of the indoor unit of the air conditioner and the radiator of the outdoor unit to maintain the cleanliness of the indoor air.
So if there is a need to buy a new air conditioner, it is recommended to pay attention to the following aspects:
1. Energy efficiency ratio + intelligent frequency conversion:
Choosing an air conditioner with a high energy efficiency ratio (APF) can save electricity bills, be more environmentally friendly and efficient, and the inverter air conditioner can also automatically adjust the operating status according to the ambient temperature to reduce energy consumption.
2. Silent Technology:
It is suitable for installation in bedrooms and other spaces that require a quiet environment, providing a comfortable sleeping environment.
3. Air Purification:
It has an air purification function, which can effectively filter out dust and bacteria in the air, and is suitable for users with children or sensitive respiratory tract.
4. Material:
Made of high-quality materials, it is more durable and reduces the frequency of maintenance.
