Midea first manufactured electric fans and air conditioners.

He Xiangjian founded the "Beijie Office Plastic Production Group" with 5,000 yuan in May 1968. In 1980, he entered the home appliance industry to produce electric fans. In 1981, the "Midea" trademark was officially registered. Started manufacturing air conditioners in 1985. So far, He Xiangjian has built Midea into a home appliance giant and a diversified enterprise with multiple business sectors such as real estate.

In 2010, Midea Group's overall sales exceeded 100 billion yuan. In 2011, its overall revenue reached 150 billion yuan, becoming a representative of "Made in China". He Xiangjian built a small business producing fans into a home appliance kingdom, representing the pioneering and innovative spirit of the first generation of entrepreneurs in the Pearl River Delta. The influence not only goes beyond Midea, but also goes beyond the home appliance industry.

Extended information:

1. The difference between fixed frequency and variable frequency

Traditional fixed frequency air conditioners will stop working when the set temperature is reached. It continues to work after the temperature changes. The inverter air conditioner will adjust the operating frequency as the temperature changes. When the temperature decreases, the inverter air conditioner will reduce the cooling speed, and when the temperature increases, the cooling speed will be accelerated to maintain the indoor temperature.

2. Purchasing Tips

When choosing the power of the air conditioner, it should be decided according to the size of the space. The cooling area of ??1 air conditioner is 10 to 20 square meters, and the heating area is 10 square meters. to 18 square meters; the cooling area of ??a 1.5-horse air conditioner is 16 to 28 square meters, and the heating area is 15 to 23 square meters; the cooling area of ??a 2-horse air conditioner is 23 to 30 square meters, and the heating area is 20 to 22 square meters. ; The cooling area of ??a 3-horse air conditioner is 33 to 40 square meters, and the heating area is 27 to 30 square meters.

3. General Principles for Purchasing

Whether to use a famous brand compressor? The compressor is the heart of the air conditioner, and a good heart is of course important. Whether to use high-quality and efficient heat exchangers, such as hydrophilic membrane trapezoidal aluminum sheets, internally threaded copper tubes, etc. Whether the large wind wheel with unequal cross-flow blades and a stepper motor are used to drive the wind swing achieve an ultra-quiet design. Whether it is super forced cooling (heating), quickly reach the set temperature. Whether the appearance of the product is beautiful and whether it is harmonious and unified with the home environment.

The cooling (heat) capacity of the product, select the appropriate cooling (heat) capacity according to the area of ??the room. Whether the product saves electricity? Generally speaking, the higher the cooling (heat) capacity and the lower the input power, the more energy-saving products. Whether microcomputer fuzzy control is used to achieve non-stop operation, and whether it can automatically defrost. Look at the noise specifications of the product. Whether it has low voltage automatic compensation function and wide voltage working range.

In addition, when purchasing an air conditioner, make sure that the fins of the evaporator and condenser are arranged neatly, that the flaps are not damaged, and that the fins and the copper tubes are tightly connected and not loose. Check the operation of the air conditioner, start the air conditioner and see if there is any abnormal noise when the compressor is running; the fan is running normally, there is a clear difference between high, medium and low speeds, and the noise is small; the appearance is smooth and beautiful, and the quality of the plated parts is good.
