Foreword
In recent years, variable-frequency air conditioners have become the dominant product in the market owing to their apparent energy efficiency and comfort, and many products have entered the maintenance phase, followed by a significant increase in the demand for maintenance services. And there are a large number of new types of air conditioners and new technologies that emerge every year, and the speed at which they are updated is increasing. The incoming maintenance staff are expected to acquire basic skills for the maintenance of the fm air conditioners in the short term, and the existing maintenance staff are required to upgrade maintenance technology, master new methods and new technologies. This series is designed to meet these needs。
The series is divided into three volumes, namely, " ultra-speed in maintenance of full-colour map-moder air conditioners " , " maintenance of electrical control systems of full-colour map-moder air conditioners " , and " elaboration of maintenance examples of full-colour map-moder air conditioners " 。
The series is based on three levels of learning (basic) - electrical control (upgrading) - the example (advanced) - and is progressive, covering the specialized knowledge and skills involved in the maintenance of fm air conditioners, meeting the needs of first-line maintenance personnel and building a complete knowledge system. The authors of the series have more than 10 years of experience in air conditioner maintenance and have worked in several large branded air conditioner post-sales services. The contents of the series are drawn from a summary of their long-standing practical experience, many of which are difficult to find in other similar books and are very valuable. In addition, the series provides free maintenance videos for readers to learn about the practical skills of the variable frequency air conditioner maintenance, which can help readers quickly acquire the relevant skills. Readers can download the video via the micro-intelligence public number e, the mechanical industry publisher。
The maintenance of the electric control system of the full colour imaged flow air conditioner is one of the series, which focuses on maintenance knowledge of the electrical control systems of the fl air conditioner. The main elements include the variable air conditioner metaware, modules and frequency compressors, the frequency air conditioner unit circuit comparison and communication circuits, the exchange of internal and outdoor circuits of the fl air conditioner, the direct fl air conditioner interior and outdoor circuits。
It should be noted that, in order to be consistent with the text symbol of the actual metaware on the circuit board, the text symbol of the selected metaphones in the book has not been modified to national standards. When measuring electrons, this book uses, if not specified, a digital table of all uses。
The book was prepared by and supported by li zhifeng and was prepared by zhou tao, li kayon, li myung-sung, ban yan, liu tsi, liu zheng, jinbun, li jia-jung, kim hwa yong, kim hsiao, li wen cai, gao lingping, xing dynasty, wang song, chen wenzheng and wang zhiqi.
