Causes of explosion of air conditioning compressor in Beijing

Due to the technical difficulty and high threshold of the industry itself, in the early 1990s, the domestic air-conditioning industry was just starting, and in the field of central air-conditioning, it was completely monopolized by foreign brands.

When air conditioning heating, the indoor air is relatively dry, which will hurt people's body fluid and make us feel dry and hot, ears, eyes, nose, throat and other places will become dry and astringent. When this situation occurs, we can timely supplement the body's water loss by drinking more water. At the same time, we can also put a basin of water indoors, which can achieve the effect of replenishing water, and can also prevent the occurrence of air-conditioning diseases.

Universal meter can be used to detect indoor and outdoor machine terminal block: whether there is 0-24 V DC voltage between 2 (n) and 4 (SI), whether there is 220 V AC voltage between 1 and 2, and no above voltage value is output, which indicates that it is an indoor fault. If any, it can be preliminarily determined as outdoor unit failure or communication failure, or directly detect the fault position by observing the fault reported by the outdoor unit fault indicator light.

Fault analysis: if there is air circulation in the system, the exhaust pressure will be too high, the exhaust temperature will be high, the exhaust pipe will be hot, the refrigeration effect will be poor, the compressor will run soon, the exhaust pressure will exceed the normal value, forcing the pressure relay to act.

The lack of fluorine in the air conditioner can not only cause refrigeration, but also cause heating effect. Now most air conditioners are heat pump type or heat pump plus auxiliary electric heating type air conditioner. The working principle of these two kinds of air conditioners is to absorb heat from outdoor air during the evaporation of Freon. If the fluorine is lack, it will not be able to absorb heat and can not work normally.

From the product design point of view, low temperature air source heat pump focuses on heating, that is, heating effect, the focus is on the operation of the equipment can Chongwen District Chunlan air conditioning installation, disassembly and drilling telephone Break through the lower ambient temperature (- 25 ℃ ~ 0 ℃), and reduce the heat aging under the lower ambient temperature, so the energy efficiency should be as high as possible. According to the current standard, the energy efficiency of heating requires heating at - 12 ℃ Installation telephone of Sanyo Air Conditioner in Fengtai District Energy efficiency cop ≥ 2.4 and - 20 ℃ heating efficiency cop ≥ 2.0. Traditional air conditioning is based on refrigeration, with heating function, which can not meet the requirements of this standard.

Strong power is also a key factor to measure a good air conditioning. Yangzi "zero wind sense" series air conditioning adopts Hitachi compressor to ensure power demand; excellent performance of the first level energy saving level, under the premise of the same working conditions and the same heating effect, the first level energy-saving technology enables consumers to use more energy-saving. The advanced numerical simulation control technology is adopted to realize the low noise operation environment; the noise analysis technology is used to effectively reduce the operation noise of the whole machine, Installation telephone of Beijing aux air conditioner Make the indoor / outdoor units completely silent; the unique quiet environment control technology, breaking through the extreme silence of air conditioning, quiet and comfortable.

On March 7, at the spring tea meeting of Vanke Group partners held by the headquarters of Vanke in Shenzhen, Vanke, a leading real estate enterprise in China, announced the list of class a suppliers in 2018, and Hitachi central air conditioning was awarded the title of A-class supplier of materials and equipment again. This also marks that Hitachi central air conditioning has become the only central air conditioning brand in the air-conditioning category that has won the honor for five consecutive times.
