1, Mitsubishi Heavy Industries
The air-conditioning products sold by Mitsubishi Heavy Industries in China are generally equipped with compressors jointly produced by Mitsubishi Heavy Industries and THACOM in Thailand. Although there are not many bright spots, after all, the technology is mature, the quality is stable and reliable, and the overall performance is good, which can reach the national first-class energy efficiency standard.
Mitsubishi Heavy Industries calls its full DC frequency conversion technology "three-core intelligent control". The triple chip controls the compressor motor, the internal and external motors and the electronic expansion valve in linkage, ensuring the coordination of refrigerant supply and motor speed, and realizing accurate speed control and temperature control. In addition, Mitsubishi Heavy Industries has mastered the PAM+PWM dual-mode frequency conversion technology pioneered by Hitachi, which takes into account rapid cooling and heating and accurate temperature adjustment of 0.5℃.

Midea once earned enough attention in the air-conditioning market because of the slogan of "electricity once a night". Although it was questioned because of the tightness of the test site and other factors, the energy efficiency of its Himalayan model was as high as 7.36. Midea's air-conditioning performance "blowout" is mainly due to Toshiba's technical support. After Toshiba split the air-conditioning business, Midea now has the largest and most complete industrial chain in China's air-conditioning industry, and its core components can be self-sufficient.
Midea's three-level energy-efficient fixed-frequency hanging machine is mainly concentrated in smart arc and power-saving star series, and the price is generally in the early 2000 yuan, while the price of the first-level energy-efficient full DC frequency conversion series hanging machine like I Youth is not expensive, and the price is stable at around 3000 yuan, with excellent cost performance.
3. Gree air conditioning
The power consumption of air conditioner is directly related to the compressor of air conditioner. Pay attention to the power of compressor when purchasing air conditioner. Gree air-conditioning compressor is well done and has strong refrigeration. Generally, two Gree air conditioners have a cooling capacity of 5000W and a heating capacity of 7700W, which can meet the normal needs of people. Moreover, Gree air conditioners are produced by internationally renowned large enterprises, and the quality is guaranteed.
4. Haier air conditioning
Haier air conditioning adopts PMV human comfort system, which can accurately adjust the indoor temperature of human body, achieve the effect of energy saving and electricity saving, and also provide automatic temperature adjustment function for people to enjoy at will. In addition, Haier air conditioning has a history of more than 20 years, and its quality is guaranteed, which is well received by consumers.
5.oak tree
The fuselage adopts fashionable and atmospheric arc design, and the bright white fuselage is clean and natural.
